Recent U.S. Energy Star is being drafted to discuss the standards of the LED street light bulbs, among the more controversial point is that life on the minimum requirements, the EPA may be consumer lamp life requirements down to a minimum of 10,000 hours from 25,000 hours, because 10,000 hours compared to three hours daily point count has more than nine years of life. The latest EPA’s standard is that you can nominal life, the minimum of 10,000 hours, of course, if the test results, you can also nominal 25,000 hours or more.
The use of 9 years is enough for general home applications, hotels, subway stations, such as places of lighting required for a long time, you can use long-life LED street light bulbs, which indicates that the EPA later no longer LED lamp life across the board, only the minimum life requirements, the lighting of different places you can demand for life lamps, reflecting differences in demand for domestic enterprises is really good, so that small businesses and large enterprises according to their own conditions, to reduce the cost of LED bulbs while different levels, but also to improve the quality of their products, accelerate product updates and promotion.
Deal with material shortages. High brightness LED high bay chips metal indium is based on. The earth’s crust in the content in rows in the 61th, strategic metals in the number two, the development and application of growing, not rich reserves of global growth, the price, the expected future will appear periodic shortages. If LED into the general illumination market, bring problem is abundant raw materials? At present, many foreign countries and institutions and enterprises have begun to explore new chip in material, our country should also pay attention to this problem, to deal with the possibility of future rising prices of raw materials, research and development of new LED material.
