Domestic LED lights to be popular before the life off"

LED chip life of up to hundreds of thousands of hours, the life of the components also have 50 thousand -10 hours, can be made out of the current domestic LED bulbs, life is only 15 thousand -2.5 hours. In yesterday's LED packaging and application products online testing new technology and new equipment exchange meeting, experts believe that LED lights to be popular, the first to live off.

According to reports, in 2011 China's LED lighting output reached 180 million, in 2012 the data is still not out of the statistics, but only the first three quarters, LED lighting exports will grow by more than 40%.

Secretary General of the Fujian optoelectronics industry association long, national semiconductor lighting technology standards working group deputy leader Peng Wanhua said at the meeting, the current domestic LED lighting industry has developed rapidly, but the problems such as low efficiency lighting, short service life and high cost, which have hindered the market penetration of LED lamp.

"To let the LED lights into thousands of households, the price must be low and now the price of energy-saving lamps almost ok. Peng Wanhua said that this is a very difficult goal, but it is not impossible, put the lamp energy efficiency, cost down, the goal can be achieved.

Peng Wanhua said that ordinary people can accept LED lights, first of all to improve the product reliability and stability, and its reliability is the main characterization of lamp life, but now the domestic LED bulb, life can only do 15 thousand -2.5 million hours".

What is the life expectancy of 15 thousand -2.5 hours? Assuming 8 hours a day to turn on the lights, then the life of a LED bulb is about 5-8.5 years. Peng Wanhua believes that compared to the life of LED chips and components, there is still much room for improvement in the life of the LED lamp.

Peng Wanhua also said that the current domestic LED lamp energy efficiency is only 20%-30%, which does not work, we must think of ways to improve the total energy efficiency of more than 50%, so as to further play the advantages of LED lamps in energy conservation and environmental protection.

At the meeting, Peng Wanhua also mentioned the United States SSL program, the program developed a LED component costs to 2015 to reach $2 / thousand lumens, in 2020 to achieve $1 / thousand lumens. The industry, LED lamp by the chip, LED components, radiators and lampshades and other components, which account for the cost of components to the lamp cost of about 1/3. Peng Wanhua believes that the plan of the United States, is currently recognized by the industry cost target, to achieve this goal, LED components of the price in the next 10 years must decline at an annual rate of 20%.
