With its excellent energy saving effect, LED lighting products has still become the preferred product in peoples daily lighting, even in the era of energy crisis.
At present, nearly all traditional lighting companies are involved in the field of LED lighting. We did not suspect that the LED’s prospects and market space. Compared to the traditional lighting products, LED lighting products market share is relatively small. Although LED lighting products are talked about as emerging energy-saving products, However, we have to be realize that LED products still exists some difficult problems.
1, Weight: Compared with traditional energy-saving lamps, it is clear that its weight is larger than traditional ones. The screw interface lamps, fluorescent light weight is of only one of the LED lamps. Because of heat sink, the weight of the fluorescent lamp can be negligible, but it will be a very serious test for LED.
2, Life: LED life bottlenecks is in the system driver board. The system drive was broken even the LED wick is not damaged. LED light decay is very serious because most of the existing LED home lighting protection is not easy to do well by size limits, large voltage fluctuations.
3, Efficiency: Why should think about the issue of efficiency? One is PF date, the other is system efficiency. As a large majority of the LED design are lower power, it commonly use of the passive PFC because of the cost pressure. The PF maybe up to 90, far less than the efficiency of active PFC. There will be much pressure for LED to replace the fluorescent lamps which is very close to the luminous efficiency.
4, Sense light: One advantage of the LED is the spectrum of pure, but it is a very serious disadvantage in the visual sense. The human eyes can not observe a single chromatographic light for a long time. ‘
5, Cooling: The LED poor heat resistance will bring much trouble for the wick life. The existing LED lights is very difficult to meet the heat dissipation requirements.
6, Price: LED driver board maybe only have 5 year life in a temperature of 70 degrees which is far from 10 years of LED wick “concept” we expected to be. Therefore, Compared to the same brightness of the fluorescent, even fluorescent lamps is only for one year life, 1W1 fluorescent lamps is much more cost-effective than the 1W10$LED.
We must solve these difficult problems if LED would like to become popular lighting tool.
