Building a Simple Led Circuit

The simple way is to use a constant current power supply and drive up to 16 LEDs in serial. No resistors needed. Additionally you can dim the LEDs with a PWM signal, a single resistor 10K to 100K = 10% to 100%, or a dc voltage (1-10Volts = 10% to 100%.A top end power supply would be a Meanwell HLG-40H (40 Watt) sell for about $30. Great power supply, 90% efficiency, 7 year warranty, no fan (even their 400W does not need a fan).Meanwell also makes a LDD series for about $6-7 from 300mA up to over an AMP.Mouser sells them

2. which is better LED or PLASMA tv?

they are all reliable television's, it is your very own very own utilization which will dictate what is extra valuable. flow to a retail keep and demo the product and spend at much less quarter-hour each on one and all and write the professional's and con's. right here's some information, Pioneer Elite plasma is the terrific television contained available in the industry, however the fee for a 50" is interior the $5,000 variety. liquid crystal show and LED suffers from action blurnes on rapid action activities, one hundred twenty HZ and 240 HZ does decrease the situation yet additionally comes at an stronger cost. LED cost is larger than the liquid crystal show. liquid crystal show and LED does consume much less capability yet no longer substantial in case you do no longer watch television better than 5 hours an afternoon. television's displayed at retail keep are adjusted to the max for extra valuable image because of the quantity of sunshine interior the keep. flow on line to abode Theater magazine and study comments on Plasma, liquid crystal show and quickly LED.

Blue Ray disc video clips are the only source of 1080P contained available in the industry now. in case you watch alot of flicks (dvd or Blue ray) and watch activities the Plasma television is extra valuable, liquid crystal show is extra valuable in case you utilize it to play video games out of your workstation or video games console. your very own eyes are the terrific choose

3. Baby led weaning and baby food?

to me, there's 2 parts to BLW. one: allowing your baby to self feed. two: feeding table foods that they can pick up and chew on easily. a baby who can self feed will not choke on food if the food is appropriate (e.g. soft or cut into appropriate sized pieces). I feel like the self-feeding is the biggest part -- if a baby can self-feed, they wo not overeat; it's like breast feeding only with foods, if that makes sense. you can not really self feed purees unless they are on a spoon (you can but your baby will make a mess and get more on his bib than in his mouth). you could try showing him how to stick his hands in the puree and put them in his mouth but I think that would be more work than it's worth. why do not you do pureed foods if you are more comfortable with that for a bit until he gets used to eating and then introduce soft solids?

4. Are blue LED lights on front headlights in UK legal?

Neon Vs LED Displays and Their Environmental Impact
On the Las Vegas strip itself, the one place in the world most famous for its neon lights, many are switching over to LED displays over neon. In fact, the neon signs that are being replaced with their LED counterparts can now be found being preserved in neon museums.LED is much more efficient than neon in many ways. First, and most obviously, it uses less energy than neon. LED signs use only 10 watts of electricity, while neon signs can use up to ten times that amount. In addition, neon signs need to have their gas replaced after about a decade, which can be expensive along with other maintenance costs. On the other hand, LEDs are known to last much longer than other forms of lighting.For neon signs, key ingredients such as argon and mercury are toxic in themselves. Any damage to the signs can cause these poisonous gases to leak into the environment and the companies that own these signs may even be held responsible for the damage that they cause.Finally, in today's fast-paced hustle and bustle, LED displays are vastly more practical than neon signs. Instead of having to change the sign manually with every new advertisement while producing more waste materials in the process, LED signs can be programmed to change on the go. They can even make use of scheduling software to display different advertisements which cater to the different crowds that pass by at different times of day, or different days of the week.There's no contest when it comes to LED vs. neon where the environment is concerned. LED is the way to go.
How Can I Wire Flashing LED Lights into a Car?
you can hook a low voltage l.e.d. into the speaker wire to get a pulse effect with the bass.. they dont draw much power at all1. CAN REGULAR LED LIGHTS GROW WEED.?yes but not that well2. TEST YOUR CHEMISTRY KNOWLEDGE! What is...?Ha Ha. "Lighten up". I get it. AlGaAs is used in LED lights, which are far more efficient and consume less energy than standard incandescent light bulbs.3. How To Choose The Best LED Vanity Mirror In 2021Makeup application is serious business. In the age of makeup YouTubers and tutorials, there are more techniques and products available than ever to suit your style and complexion. However, one often overlooked part of applying makeup is the lighting. You can have all the expensive cosmetics in the world, but without the best LED vanity mirror to show your face in detail during application you could be making mistakes and not even noticing. Let's see how to choose the best one as well as four different LED vanity mirrors we found for you. If you are in a rush, take a quick glance at the products we will talk about here and which one we consider the best. If it is your first time purchasing a vanity mirror with LED lighting, you may not know exactly what to look for, and which features make a suitable mirror. There are a few important criteria to consider to ensure you make the right choice. Which size you opt for will depend on a few factors including whether you plan to transport your mirror around (there are some small portable LED vanity mirrors if so). The space in which you are installing your mirror is likely to dictate the size of mirror. If you have a large vanity table you may wish to install a large desktop mirror, or if you have a space reserved in your bedroom or bathroom a big, wall-mounted vanity mirror can look impressive as well as being functional. You might think that LED lights are LED lights, but actually there are some subtle and nuanced differences to help you to make your decision. Something I definitely recommend as a feature of LED vanity mirrors is dimmers. Some of these lights will just let you switch them on or off, with no extra controls. The advantage of a dimmer is that the light can be set to your preference and the environment, plus altered according to the natural light available. If you are applying makeup in broad daylight, recommends using natural light as much as possible, with a warm, bright light such as LED lighting to compliment this as required. LED lighting tends to be quite an economical way to light up a space, but ensuring you purchase an energy efficient LED vanity mirror can save you a lot of money in the long haul. report a 50% increase in the efficiency of this technology since 2012. This saving is especially evident if your mirror is not just for personal use but for business use. These products are popular among makeup artists and fashion professionals and in these scenarios they can be on all day, the difference made can be huge.. LED vanity mirrors are extremely useful, but that does not mean they can not look great. LED mirrors can provide some brilliant ambient lighting and an impressive statement piece in either bedroom, dressing room or bathroom. They add a real touch of class and can fit either modern or classic designs. even reports that subtle, ambient lighting can help give a glamorous look to a bathroom. One controversial topic, and decision to be made, is whether to purchase the LED mirror with lights built in, or whether to purchase a separate LED lighting kit. Though this article is focusing mainly on mirrors with lights included, it is definitely worth mentioning the lighting kits. If you already have a vanity mirror which is fixed to a wall or hard to remove, it might be worth considering a lighting kit to add the LED lights on to an existing mirror. If you are purchasing a new mirror, there is really no benefit to one of these bolt-on light kits. It is extra hassle that can be avoided just by buying a great LED vanity mirror. With plenty of lights available, and other forms of lamp made specifically for makeup and illuminating faces, what are the benefits of LED? The color temperature and tint does not give a biased view of your face or provide a tint that might give you a warped view of the makeup you have applied and your coloring. Tungsten or 'yellow' lights may give you a less accurate view. Energy efficiency. As already alluded to, LED lighting is one of the most energy efficient sources of light and will save energy due to their intelligent design. They are long lasting. LED lights rarely need replacing meaning less maintenance and annoying upkeep. Heat. LED lights do not tend to overheat, as many bulbs can. This avoids any risk of burns, especially useful if you are using your vanity mirror in a public space or somewhere children are. Let's take a look at, probably, the best products on the market. Here's the comparison table of the best LED vanity mirrors from our point of view. Below the table, you can find the detailed description of each product. The Chende vanity mirror is an elegant tabletop design of vanity mirror. It is available in multiple designs, one of which is bound to suit your space. Though advertised as a tabletop mirror, it also has the option of being wall mounted should you wish. Available with or without inbuilt makeup drawer. None Dimmable lights to adjust to your preference. None Available in black, white and frameless designs. None Available in round or rectangular designs. None This mirror has been put through would rop tests' to check the quality and durability. None Metal hooks included at the back for wall mounting if this is preferred. None Has a power outlet included for straighteners, hair dryers or other appliances. Power outlet can draw power from the bulbs. None The control knob for the dimmer is not the sturdiest and you need to be delicate with it. This is another type of LED vanity mirror built with bathroom design in mind. The LEDs come in the form of a 40mm stripe around the outer edge of the mirror. The bulbs within are designed to have an incredible 50,000 hour lifespan. The intelligent and modern design is backed up by the 'touch' function, allowing you to turn it on in the center at the bottom with a touch sensitive command, much like an iPhone. None Touch controls for a modern look and feel. None Available in two different sizes, King and Queen, to suit the space you have available. None Comes with everything you need to affix to the wall. A relatively simple process. The lights could be brighter and need to be twinned with an ambient room light. None The 'nightlight' illuminating the touch controls has no option to be turned off. If you are looking for an impressive look for your bathroom as well as a functional and flexible mirror, this could be the answer for you. The LED lights are in the form of a strip all around the outside of the rectangle. Though this does not have to be used in a bathroom, it is certainly designed with this use in mind. Available in four different sizes, 2028, 3628, 5528 and 5536. None Moisture proof stripe around the outside so no issues with bathroom moisture will arise Has to be wall mounted with no option for free standing. None No dimmer setting for choosing your light level. None Can be confusing to mount and install if you are not overly DIY savvy. The second Chende LED vanity mirror we've mentioned in our list. This Chende mirror is similar in many ways to its smaller sibling. The 'Hollywood' design clearly looks like it would fit perfectly in a film set dressing room. The gorgeous looks of the exposed bulbs make this a popular choice for those who are going for a less modern look. Dimmable lights which are easy to adjust. None Available in black, white or frameless designs. None Metal hooks included to allow for wall mounting. Power outlet can take power away from the bulbs and cause dimming. None The control knob for the dimmer is not the sturdiest. None Occasional reports of flaws and chips from the shipping process, always a risk with large, delicate items. What Is The Best LED Vanity Mirror? In terms of which LED mirror I recommend, Chende definitely stand out as the best brand, with the smaller, 'portrait' shaped design implemented in being my recommendation out of these. It gives a great blend of quality, looks and value for money, and is big enough for most uses. It can be placed on top of a vanity dresser or similar, or it can be wall mounted. One of the few models to offer this choice. Both Chende models are great, but we recommend the portrait model for not just great looks and features, but value for money. Different users are looking for different things from their mirror. If you are looking for something a little different such as a bathroom vanity mirror or a portable mirror, rest assured that there are options worth looking at.

Can i hook up my led lights to the remote wire on my amp for a constant glow?Probably not. The amp remote wire is extremely low current, typically less than 1A. If the amp turn-on circuit and the LED's combined draw more current than the remote wire can deliver, it will likely damage head unit. Why do you want to connect the LED's to the amp remote? Why not connect them to a switched 12V source at the vehicle fusebox or perhaps even to a constant (nonswitched) source and add a toggle switch to turn them on/off?7.

Add 50% and round to the nearest standard fuse rating. But this may not be enough - if the fuse is slow, it wo not be effective in protecting the downstream part of the circuit, including LEDs.
Whats the Difference Between LED Lights and Regular Lights?
What’s the Difference Between LED Lights and Regular Lights?What is the Difference Between LED Lights and Regular Lights? If you are considering upgrading your lighting system to LED light fixtures, you are making a great choice. You will be making huge strides forward in your commercial business's energy usage, as well as doing the environment a favor. We here at LED Wholesale Supply, as vendors of commercial lighting, promise that you are making a decision you wo not regret. However, you still might be curious about what makes all LED brands different from other types of lighting-and, therefore, so great for your company. Maybe you even wonder, on a structural level, how LED lights work, as opposed to their counterparts. Learn all the details below from a supplier of wholesale LED lights. What Exactly Are LED Lights? To know how LED lights are different from other lighting types, it's necessary to know what LED lights even are. Even though this technology has been around for years (it's the same thing that lights up some digital clocks and newer traffic lights), not a lot of people know exactly how they work. LED is an acronym; the name stands for "light-emitting diode," which is a nod to how LEDs work on a structural level (diodes are specific types of electricity-transferring structures that are not exclusive to LEDs). An LED creates light by moving electrons-small, negatively-charged particles-through a tiny piece of matter called a semiconductor, which is a process that excites these particles and creates light. In contrast, other types of lighting do not rely on solid matter to create light, but rather gas in a chamber or a vacuum. It is due to the functionality of the diode that LEDs do not need mercury to work, as opposed to fluorescent lights, which rely on the elements' changing form from a liquid to a gas to produce light. Therefore, LEDs render themselves relatively environmentally sound, as their lack of mercury means that the toxic substance cannot leak into the environment. As a side note, this is also the reason why fluorescent lights should be recycled during retrofitting and similar procedures. Yes, the amount of mercury contained in a fluorescent light is small, but on a larger scale, careless disposal can have a severe environmental impact. In conclusion, LEDs create light by exciting electrons inside solid semiconductors. They differ from fluorescents in both their structure and the elemental substances they use to create light. What Does This Difference Mean For Your Business? The unique design of LEDs makes them an ideal choice for commercial businesses everywhere. They truly are the lighting choice of the future, and there's a reason you will find them being used in forward-thinking businesses across the globe. What things do LEDs bring to the table that other types of lighting (fluorescent included) can not ? What unique benefits can you expect from your LED installation that you would never expect from different types of lighting? ● Great savings. Yes, when compared to other types of lighting, the initial costs of LED fixtures can be slightly higher (though recent innovations have made the technology much more affordable than in previous years). However, you truly get what you pay for; LEDs can last for years-decades, even. This means that in the long run, you are less likely to invest in fixture replacement or new LED light bulbs, which puts more money in your pocket. Furthermore, LED lighting is strikingly more energy-efficient than many other types of lighting, meaning that your energy bills could also be significantly lower than they would otherwise when you use LEDs. As a bonus, because LEDs emit little heat, they could also mean a cut to your AC bills in the warmer months. ● Respect for the environment. As stated above, LEDs last for a very long time; you could reduce the number of light fixtures you will need to replace, which can reduce your firm's overall waste. Moreover, LEDs use energy more efficiently than incandescent lights, which means less stress on the environment, as your firm's energy demands could be smaller. Relatively small heat emissions from LEDs also contribute to a possible reduction in your business's carbon footprint. ● Respect for your facilities. Anything that consumes electricity also generates some degree of heat. However, due to LEDs' energy efficiency, they emit far less heat than many other traditional bulb types. This could mean less damage to your facility's walls and infrastructure. After all, many wallpaper and trim types are not designed to withstand being roasted under fluorescents or incandescents day in and day out. We are more than just a light bulb supplier and more than just a wholesaler. We pride ourselves in selling the very best in LED fixtures and lamps, and we would be happy to answer any of your lighting questions. Give our office a call today at 952-392-9117.

Minerals in Boiled Water (or Food) Reacting with Aluminum Sauce Pan -- Would a Person Be Ingesting A
Minerals in boiled water (or food) reacting with aluminum sauce pan -- would a person be ingesting aluminum?The acid in fruits and vinegar will leach some aluminum. That is what makes the ring. The amount is probably too small to worry about— — — — — —URGENT! Boiled water help needed?Stop FASTING— — — — — —What do you think bout muh promblem?I recommend not cleaning it with anything BUT sea salt mixed with warm water. I used it for all of my piercings and all this other rubbish people are giving their customers annoys me to no end. Aftercare: 1/4 teaspoon of non-iodized sea salt mixed with 8 ounces of boiled water [left to cool down a bit so you do not burn yourself!] 2-3 times a day. [Morning, midday, night] Infection= bloody/yellow/green smelly pus, a lump, painful, red and hot to the touch. Try to keep your hair out of your face, maybe clip it all back when you are sleeping as when you are awake you can just brush it out of your face. Do not play with it and take extra care when putting clothes on etc. Prop yourself up with lots of pillows when you are sleeping.— — — — — —Is it true that boiled water is better than bottled water?Yes it is true. When you boil water it boils away anything harmful that was in it. Plus now with bottled water the chemicals from the bottles can leak into the water and harm you.— — — — — —Why is ice made from boiled water clear?The short answer: Cloudy ice is caused by gases (mainly nitrogen and oxygen) dissolved in the water that come out of solution when the water freezes. The small bubbles trapped in the ice cause the white appearance. Boiling the water removes the air dissolved in it, producing clear ice as a result. Assuming that other impurities do not produce the same cloudy effect.The long answer: Impurities present in water:Gases: Water at 20°C normally contains about 15 ppm dissolved gases, which is the equivalent of 1 volume of air per 50 volumes of water. These are the same gases present in air, but not in the same proportions since some are more soluble than others: it's about 63% nitrogen, 34% oxygen, 1.5% argon and 1.5% carbon dioxide.minerals: Tap water contains dissolved minerals, mainly Ca and Mg. They can be present in the form of bicarbonates: $Ca^2(HCO_3^-)_2$ and $Mg^2(HCO_3^-)_2$ (these only exist in solution, not as solid substances), and as calcium and magnesium sulphate. If the water passed through a water softener, the Ca and Mg ions may have been replaced by (twice as many) sodium or potassium ions.The effects of heating the water:removing dissolved gases: higher temperature favors endothermic reactions (Le Chatelier's principle). For the gases present in water, dissolution (at room temperature) is an exothermic process, so their solubility decreases when the water is heated. The solubility of gases does not reach zero at boiling point, nor does it necessarily decrease over the whole temperature range. For nitrogen in water, the enthalpy of dissolution becomes positive around 75°, and its solubility increases above that temperature. At 100°C, solubility of air as a whole is $0.93 * 10^-5$, about half the solubility at 10°C, $1.82 * 10^-5$. removing dissolved minerals: Heating the water promotes the conversion of soluble Ca and Mg bicarbonates to insoluble carbonates ($2 HCO_3^-$ → $CO_3^2- H_2O CO_2$) which will come out of solution (as limescale). The sulphates (sometimes referred to as "permanent hardness"), and the sodium or potassium (bi)carbonates stay in solution. The effect of boiling:How do gases make ice "milky/cloudy"?— — — — — —Does anyone know of an easy home remedie for mouth ulcers?Definitely the warm salty water, I would use boiled water that has been let cool down. Then, if they are hurting badly, try some teething type gel from the shop/pharmacy so you can sleep at night— — — — — —i have a cold!?!?! PLEASE! help me! READ THIS! food to help..?Lemon drink - lemon juice, water and honey and a dash of red pepper - sweating the impurities out. eat fresh leafy vegetables with lemon juice and olive oil Soups are good - a nice light vegetable broth with vegies and ramen noodles would be good - a vegie juice if you have a juicer I found these - they might help Shoga-yu (Hot Ginger Drink) Ginger is said to be an excellent remedy for the early stages of a cold since it keeps the body warm and stimulates perspiration. Use fresh ginger. Ingredients:(1 serving) 2 tsp grated fresh ginger 1 tsp sugar or honey 1 cup boiled water Put ginger and sugar in a cup. Pour boiled water in the cup and mix well. 3. O-kayu (rice porridge) O-kayu is the most common "sick food" in Japan. O-kayu is cooked very soft, so it's easy to digest and is easy to eat. A plain o-kayu does not include other ingredients than rice, but you can add vegetables or meat, depending on your appetite. Green onion is commonly used for home remedy for cold in Japan, so it's good to sprinkle some chopped green onion if you would like. Ginger-Cinnamon Tea (Ginger is also purported to soothe an upset stomach.) 1/2 cup thinly sliced fresh ginger 6 cups water 2 cinnamon sticks 2 tablespoons honey or brown sugar lemon wedges for garnish if desired In a saucepan, simmer ginger, cinnamon, and water 20 minutes, or more for stronger tea. Add honey or sugar and strain tea through a sieve. Hot Lemonade (Great for a sore throat.) 4 lemons several slices of ginger root honey to taste Juice several lemons, then scrub the peel well. Slice it thinly, and add to the juice. Cover all with plenty of boiling water, cover, and steep until cool. For added benefit, add several slices of ginger root before covering with water. Strain off the liquid, add honey and additional water to taste. Drink hot. Mixed Greens and Fennel with Ginger Dressing (Ginger is purported to be great for a cold. So is fennel.) 1 bag of fresh spinach or mixed salad greens 2 fennel bulbs (cleaned, cut in half lengthwise, and sliced thinly crosswise) For thedressing: 2 scallions, finely chopped 1 garlic clove, minced 2 tablespoons oriental sesame oil 2 tablespoons soy sauce 2 tablespoons rice vinegar 1 tablespoon chopped, peeled fresh ginger 1 tablespoon honey 1/4 cup canola oil Blend first seven dressing ingredients in food processor. With machine running, gradually add oil and process until well blended. (Can be prepared 1 day ahead. Cover and refrigerate. Let stand 30 minutes at room temperature before using.) Toss fennel and greens with dressing. Enjoy! Hope you get better soon also my mother swears by this treatment - get a cup of warm water and add a 1/2 teaspoon of salt and go to the bathroom and inhale the salty water through your nose and spit it out of your mouth- its really disgusting buts its very very good for a sore nose and also good for people with infections. You will find you will be able to breathe better. i know its awful but I have used it when I have been desperate.

The cost reduction was passed to consumers, making LED and energy efficient appliances an affordable for all. Average prices of LED bulbs under UJALA vary between Rs.60-70 (subject to various state taxes) with a 1-year warranty. The UJALA scheme, which started with distribution of LED bulbs has now expanded to include variety of energy efficient products like fans, tube-light and air conditioners, etc. With a network across India, EESL distributed more than 36.26 crore energy efficient LED bulbs, saving over 47,000 mn KWh, 3.8 crore tonnes of CO2 emissions and Rs 18,800 Crore per year. This also reduced peak demand by 9,400 MW. EESL plans to replace 77 crore inefficient bulbs by LED bulbs by March 2019. This would reduce load in the country by 20,000 MW and save of 10,000 crore kWh per year. Consumers would save Rs. 40,000 crore every year, after an average tariff of Rs. 4 per kWh. EESL procurements conform to BIS specification IS 16102 Part 1 and Part 2: 2012 for self-ballast lamps. Further, these bulbs carry a 3-year free replacement warranty against technical defects. At the bidding stage, the prospective bidders are required to provide, along with their bid documents, the test reports from National Accreditation Board of Laboratories (NABL) accredited labs. At the distribution stage, EESL picks up samples of LED bulbs at each place where the distribution is taking place and from the manufacturing facility in a random manner and gets it tested— — — — — —Main fuse blows when light bulb blows?This is entirely normal behaviour for filament bulbs. When the filament breaks, one or other loose end can short against the other terminal. Neither CFL nor LED bulbs have this problem (the rectifier diodes in a CFL can theoretically fail short-circuit, but it's extremely rare in practice).— — — — — —How much electricity does a strand of 300I am assuming of course led lights.? If so, an led bulb uses approx. .05 watts and considering you using 2400 led bulbs, that would amount to 120 watts. With that you probably use more power out of your bathroom light fixture . You will be fine if you use led bulbs— — — — — —Are you proud to live in a country where we will be allowed to choose what lightbulbs we can use?This is a good question I am sure that you mean incandescent bulbs with filaments which you may prefer to use. Those experts can be tunnel visoned sometimes. They are focused on the illumination value of the bulb whiile ignoring the heat value of the incandescent bulb. . In wintertime, it is more benefical to use incandescent bulbs as they are hotter and keep your home warmer than CFL bulbs. I dont know about LED bulbs as they are still too expensive and not as widespread yet. But for summertime, incandescent bulbs makes your home too hot and force your air conditioner to kick up a notch . . Basically, I would ignore anybody who use incandescent bulbs during wintertime as it is really neutral as far as energy conservation goes. No matter what you feel or think about energy conservation, it is here to stay. We have to be more careful wtih the solutions . For example, I suspect that rooftop solar installations dont help at all because it cast shadows on the roof that makes the attic colder than before . It cancels out the gain we get in electricity from the sun with the loss in heat we get from the Sun in the attic. It is a cruel hoax. that. Nobody cares if you can afford $10 gasoline or $500 oil barrels. You have to conserve energy, period. Same thing goes to firewood which endangers our heatlh and drive up health costs. I have no proof because the experts is not interested yet. . I am sure that they will before too long. The world is burning way too much firewood and cowbricks
3 Reasons You Need Parking Lot Flood Lights

Five Magic Weapons to Help the LED Lighting Industry Break Through the Siege
The domestic LED industry is turbulent, and a new round of reshuffle is about to or is being staged. As the latest application of LED, the LED lighting industry urgently needs practical and effective solutions in order to be less cold in the cold winter of the industry. Five key breakthroughs are listed below. We look forward to effective results!1. Local protectionism in supporting policiesSome local governments have issued policies to cultivate local LED lighting enterprises and give priority to local municipal landscape lighting and traffic lighting, which makes the LED lighting downstream enterprises have to focus on participating in the bidding of government projects. In addition, LED lighting standards have not been formulated in China, and the application standards are different in different regions, which leads to great resistance when enterprises explore the market across regions, and also limits the overall development of LED lighting industry.2. Lack of brand awarenessA large number of led enterprises, mixed with good and evil people, uneven product participation and no independent brand have led to the theft of some patents and frequent infringement events.3. Civil functions urgently need policy supportBecause the price of LED lighting lamps (LED bulb lamps, LED projection lamps, etc.) is more expensive than traditional sodium lamps and the one-time investment is large, local governments dare not invest boldly, resulting in the promotion and application speed of LED lighting lamps in China far behind that in western countries. At present, lighting associations in various provinces and cities are responding to government policies, such as Shanghai Lighting Association, Guangzhou Lighting Association, etc. lamps in various provinces and cities are sales hotspots. At the same time, the vast majority of LED lighting in China is still used in public facilities, and its daily function needs the support of relevant policies.Many bottlenecks still restrict the development of LED industry and can not be popularized like energy-saving lamps. However, it is gratifying that in recent years, more and more led enterprises have focused on the market, looking for channels suitable for their products and paying attention to the differential advantages of market competition; Gradually strengthen the publicity and training of their own brands; Pay attention to the overall regional environment and begin to standardize the market competition order.4. Technology and equipment bottlenecksIn terms of LED substrate material technology and epitaxial wafer production equipment, there are obvious bottlenecks in the domestic LED lighting industry. The independent innovation and patents in the LED field of Chinese enterprises are mainly concentrated in the packaging stage. In the most critical aspects, such as white light, heat balance of high-power LED lighting lamps (LED bulb lamps, LED projection lamps, etc.), durable and efficient phosphors, technical patents have been monopolized by enterprises in Europe, the United States, Japan and other countries. There is still a big gap between domestic LED lighting products and international products in terms of brightness, luminous efficiency, anti-static ability, anti leakage ability and quality control level.5. Lack of product pricing powerThe scale of domestic led enterprises is small and industrial resources are scattered. Core chips, especially high-power LED chips, mainly rely on imports from abroad. A single small and medium-sized manufacturer can only import expensive chips from abroad, resulting in low bargaining power and high costs.
