With its excellent energy-saving and environmental protection effects, LED lighting products have become the first choice for people's daily lighting in this era of energy crisis.
Almost all traditional lighting companies are now involved in the field of LED lighting. We do not have to doubt the prospects and market space of LEDs. For the time being, compared with traditional energy-saving lighting products, the market share of LED lighting products is actually relatively small. Although LED has been talked about as an emerging energy-saving and environmentally friendly product, and even worshipped it, it must be clearly realized that LED products are not omnipotent, and there are still some problems that are difficult to solve.
Energy saving and environmental protection, still in the ointment
I. Weight: Compared with traditional energy-saving lamps, the weight of LED lighting is obviously larger. In the spiral type of luminaire, the weight of the fluorescent lamp is only a fraction of that of the LED luminaire. Since there is no problem with the heat sink, the weight of the fluorescent lamp is negligible for the lamp holder, but the weight of the LED is a serious problem for the lamp holder. The test.
Second, life: LED life bottleneck in the system driver board, often LED wick is not damaged, the system driver has been broken. In addition, the light decay of LED is very serious. Most of the existing LED household lighting is limited by volume, and it is difficult to do very well in terms of protection, in areas with large voltage fluctuations and serious interference.
Third, efficiency: Why should we consider the issue of efficiency? One is the PF value and the other is the system efficiency. Since most of the existing LED designs are low-power, the passive PFC (filled valley) is used for the cost pressure. The PF may be up to 90, which is much smaller than the efficiency of the active PFC, and the LED is replaced by LED for the country. Fluorescent lamps that are very close in efficiency are a stress.
Fourth, the light sense: One advantage of LED is the pure spectrum, but this is a very serious disadvantage in the visual. The human eye can't observe a single-chromat light source for a long time. The LED is dimmable, but it is more troublesome, more professional, and needs theoretical and a large amount of research data support. It is a lot of homogenizing material manufacturers or LED light source manufacturers or solution providers. Hard to achieve.
5. Heat Dissipation: The poor heat resistance of the LED will bring about the problem of the life of the wick. The design of existing LED lamps is often difficult to achieve heat dissipation. In a field where heat dissipation is very demanding, it uses very inferior passive heat dissipation methods, and most of them are air-cooled or even closed air-cooled.
Sixth, the price : LED driver board may only last 5 years (home) at 70 degrees temperature, far less than the "concept" of LED wick for 10 years. Therefore, even for fluorescent lamps of the same brightness, even fluorescent lamps are only 1 year old. Lifespan, 1W1 yuan fluorescent lamp is far more cost-effective than 1W10 yuan LED. Especially when the LED lamp is damaged, the wick is not broken, but the whole lamp is replaced.
At the beginning of the market, advocate brand building
In order to become a popular lighting tool, LEDs must solve the above-mentioned difficult problems. Of course, any new product must go through the market's running-in and time inspection. As a global energy-saving engine, LED faces the above-mentioned shortcomings, but it still has the advantage that traditional energy-saving lamps cannot surpass.
In addition, branding is also a major problem facing the current LED lighting industry. Throughout the global lighting market, the LED lighting industry has developed rapidly. Although there are no so-called leading companies, there are also many excellent brands and manufacturers. Diligent lighting, rectangular lighting , Zhen Mingli, Lehman, etc. The leader in the LED lighting industry. The lighting industry must take the branding route, especially in the LED lighting industry. The price of LED lighting products is much more expensive than traditional lighting products, so it needs brand to establish credibility to win the general trust of consumption. According to the relevant personages of Guzhen, the LED market in Guzhen is beginning to be chaotic, the brand is blurred, shoddy, and the concept of grade is blurred. At present, there is a lack of benchmarking companies in the LED field.
It is learned that Changfang Lighting has officially moved to Pingshan New District in recent days, and has increased the research and development of finished LED lamps and brand building in the new industrial park. In the next few years, Changfang Lighting will shift its focus to the production of finished lamps, brand building and brand marketing channel system construction. According to the introduction of the sales director of Changfang Lighting, although there are many difficult problems in LED lighting, there is no way to solve these problems. The rectangular lighting has recently improved the practicality and made the real boss in the LED industry.
