LED light under the "defects""

LED lighting products with its excellent effect of energy saving and environmental protection, the energy crisis in the 1990s, behoove becomes the preferred product of daily lighting. Almost all current traditional lighting companies are beginning to get involved in the field of LED lighting. We don't have to doubt LED's prospects and market space. At present, compared with the traditional energy-saving lighting products, LED lighting products market share is relatively small. Although LED as a new energy saving and environmental protection products being talked about, and even worship, but must have a clear understanding that the LED product is not a panacea, currently there are still some problems difficult to solve. Energy saving and environmental protection,: still in want of perfection, weight: compared with the traditional energy-saving lamps, LED light weight obviously big. The lamp screw interface, one of several fluorescent lamps weighs only LED lamps, due to the absence of the heat sink, the weight of the lamp holder for fluorescent lamp is negligible, but the weight of LED is a serious test for the lamp holder. , two life: Life bottleneck of LED system in the drive plate, often LED wick is not damaged, the driving system has been broken. In addition LED attenuation is very serious, most of the existing LED home lighting volume restriction, protection is difficult to do well, the voltage fluctuation interference region. Three, efficiency: why should we consider the problem of efficiency? One is the PF value, one is the system efficiency. Because most of the existing LED design are low power, by the pressure of the cost using passive PFC (valley fill), PF may be up to 90, far less than the active PFC at 99 efficiency for countries using LED to replace the fluorescent lamp luminous efficiency is very close to the pressure. , four light: LED is an advantage of spectrum pure, but it is in the visual above a very serious disadvantage. The human eye is not a long time observation of a single chromatography light source, LED light adjustable, but more trouble, more professional, need theory and a large number of research data, many are light material manufacturers or vendors or suppliers of LED light source is difficult to realize the scheme. : LED five, poor heat radiation will bring the problem of the service life of the wick. The existing design of the LED lamp is often difficult to meet the requirements of heat dissipation, in a very demanding field of heat dissipation, but the use of very poor passive heat dissipation, and mostly air-cooled, and even closed air cooling. Six price: LED driver board at a temperature of 70 degrees may be only 5 years of life (home), far from the LED wick 10 years "concept". So compared to the same brightness of fluorescent lamp, fluorescent lamp, even if only 1 years of life, fluorescent lamp 1W1 yuan than 1W10 LED is much more cost-effective. In particular, the LED lamp is often damaged wick is not bad, but the whole lamp replacement. At the beginning of the market, promote brand building: LED to become a popular tool for lighting, must solve the difficult problem. Of course, any new products have to go through the market and the time test. LED as a global energy saving engine, although faced with the above shortcomings, but still has the advantages of traditional energy-saving lamps can not be beyond. In addition, main problems of brand construction is the current LED lighting industry faces. In the global lighting market, the development of LED lighting industry relatively rapid, although there is no so-called leading enterprises, but there are also many outstanding brands and manufacturers, KingSun lighting, rectangular lighting, neon, such as Lehman is a leader in LED lighting industry. The lighting industry must take the brand route, especially the LED lighting industry, LED lighting products have become more expensive than traditional lighting products, so it needs to establish the credibility of the brand, to win the trust of the consumer generally. According to the ancient town of the relevant parties, the ancient town of LED market began to confusion, brand, shoddy, fuzzy concept of fuzzy grade etc.. At present, the field of LED lack of benchmarking enterprises. Reporter before calling the rectangular lighting sales director to understand, rectangular lighting has recently formally moved to the new industrial park in Pingshan, increased R & D efforts on product LED lamp and brand building efforts. In the next few years, rectangular lighting will shift the focus to the production of finished products, brand building and brand marketing channel system. According to the rectangular lighting LED lighting sales director, although there are a lot of difficult issues, but these are not without a solution, rectangular lighting before the improvement of the utility has increased, to do a real leader in the LED industry.
