Zong Peimin, chairman of Zhejiang Huarui Investment Management Co., Ltd., which has invested in several LED companies, believes that there are still several obstacles to overcome in China's LED industry:
First of all, we must improve the luminous efficiency of LEDs. LED lamps want to truly enter the general consumer family, need to increase the luminous efficiency of warm white color LED to 100lm / W (lumen / watt), the cost of lighting can be reduced by 25%, the cost of electricity will be more cost than traditional bulbs Advantage.
Second, we must solve the heat dissipation problem. High-power LEDs have high requirements for heat dissipation technology. When the ambient temperature reaches a certain height, the LED will quickly produce light decay, resulting in a decrease in LED lifetime. Only by solving the heat dissipation problem of high-power LEDs can the application of high-power LEDs be widely promoted.
In addition, to reduce the price of LEDs. Price is a key factor that directly affects the popularity of LED lighting. Although the total cost of LED lamps (including acquisition cost + energy cost + maintenance cost + waste disposal cost) is lower than that of incandescent lamps and fluorescent lamps, consumers still choose the cost of acquisition. Standards are not too concerned about high quality or versatile features.
