Rationally look at the current problems faced by LED lighting products

From March 2006, high-power LEDs showed their heads and the LED fire was ignited. In the country, it was originally expected that LEDs would replace most home lighting in 2008. In 2010, it reached a large popularity. Looking back, the domestic forecast is not realized. In contrast, foreign progress is more rigorous, and design planning is relatively long-term. Looking at the manufacturers who are now doing LEDs, the big ones will focus on the light source and the chip part, and the whole lamp will not hurt. It can be understood that the whole lamp structure of the LED is still in a gestation period. It is impossible to quickly popularize. Not only the price problem, how to deal with heat dissipation, whether the shape can achieve the heat dissipation effect, whether the external energy can be accepted by the public after the purpose of heat dissipation, sum up the following points to be confirmed:

1 The current market is mixed with dragons and snakes. Every family boasted about Haikou, saying how good their products are, how to live longer, and even worse, taking 80W LED street lights and 250W sodium lamps to save energy. Take 40W fluorescent lamps and 20W LED fluorescent lamps for energy saving and brightness. Anyone with a little optical common sense knows that there is no comparability between the two, and the current LED light efficiency, and the luminous efficiency of sodium and fluorescent lamps are not a grade. If you want to talk about the angle of illumination, add a reflector to the fluorescent lamp to try to make the LED energy-saving.

Of course, technology is developing, and LED progress is obvious to everyone. I am not an LED opposition group, but it is not a fanatic group. From another angle, LEDs are all technical personnel or sales personnel associated with the factory. It has practical significance. It is the ultimate goal to make money. Can it be batched, whether it will make money, not determined by that person, it is decided by the consumer, as an engineering technician, rigor is very important, blindly put an immature The large-scale production of products is directed to production. As a business, regardless of the facts, it is extremely irresponsible for individuals and society.

Whether 2LED can be applied in all occasions, the light source not only pays attention to luminous efficiency, but also has the problems of color rendering index and color tolerance. According to the concept of LED lighting fanatic group, LED is the size of all. It can be used in any occasion, whether indoors or outdoors, stadiums, large docks, and some people claim that LED light bulbs are used as projection light on the projector. Its posture makes people think about him. A product with a color rendering index of less than 80 can be used as a projection bulb! ! !

No product can be perfect, and it can be used in the place that suits him to make the best use of its value. The LED concept has long life and good anti-vibration performance. It is very good for use in cars. LED low voltage is used under water. Very safe, LED energy-saving, used in long-term lighting, but in contrast to the obvious color index requirements are not too high, can be competent. Not recommended for large books and classrooms, the color rendering index, glare, has a great impact on long-term reading, worrying about hurting students' vision. LEDs can be used on streetlights where lighting requirements are not high, but are not suitable for use on highways (if the luminous efficiency of the color rendering index increases and is different). LED can not be used in large sports

Listing these is just to illustrate a reality. Don't expect a product to replace all products. The use is different and the requirements are different. Just like we travel every day, sometimes we need to take a car, sometimes we drive ourselves, sometimes we are more willing to walk, but sometimes we have to fly. Everyone knows that the plane is the fastest. But if you are not 20 kilometers away, you have to fly. Everyone knows that walking is the most economical and fitness. But if anyone wants to walk from Guangdong to Beijing, if they calculate the cost, they will know that walking is more expensive.

Personally, LED light that solves the problem of LED light decay and designed to grow life is suitable for occasions where long-term lighting is used. In places where lighting requirements are not too high, there are actually many places in these places, large warehouses (some are 24-hour lighting), government Building, public security building. Toll stations, gas stations, large supermarkets, etc. Home lighting has higher requirements on the shape, and the requirements for color rendering index are not low. At present, it can be used, but it is not very useful.

3 cost performance and energy and environmental issues, now the use of aluminum is mostly used for heat dissipation. Not only expensive (6W LED as the standard almost doubles the price of the whole lamp), although there is so-called high thermal conductivity ceramic heat dissipation, but there is no actual finished product flowing in the market. Whether the use of aluminum in large quantities is irresponsible to society, not only consumes energy, irrational control and recycling, but also causes environmental pollution. Aluminum is an element that is very harmful to the human body. Excessive involvement in the human body can lead to multiple diseases

Compared with traditional lighting, LED lighting has its unique advantages and development prospects. However, LEDs are not suitable for use in all places. The positioning of LED lighting should be cautious, and blindness will only bring negative effects. The early LED resistance and resistance lamp cups, the hot straw hat LED fluorescent tube in the previous two years, is the best proof.
