. Internally generated photons emitted to the outside of the chip can not be fully and finally into heat Honghu led electronic display, which is the main part, because this is called an external quantum efficiency of only about 30%, most of them converted to heat up. As previously mentioned, although incandescent light efficiency is very low, only 15lm / W or so, but it almost all the electrical energy into light energy and radiate out, because most of the radiation is infrared, so low light efficiency , but it eliminates the problem of heat dissipation. LED business development opportunities facing First, although China in the upstream LED epitaxial wafers, chip production with the United States, Japan, EU production is technically a gap, but due to demand at home and abroad is a huge market applications led electronic display, and the end-consumer market was diversified decentralized structure, not easy to form a market monopoly Xiaogan led electronic display, LED downstream firms thus giving tremendous opportunities for development, especially for the relatively backward technology enterprises in China, have a greater survival and development space. Yellowstone led electronic display, 金锐光 electricity (certified), led electronic display provided by the Science and Technology Co., Ltd. Yichang 金锐光. Yichang Jinrui Guang Technology Co., Ltd. (www.ycjrgd.com/) Hubei Yichang, electronic, electrical project co-leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . In Jinrui Guang power leadership with the staff warmly welcome all inquiries negotiations to create a better future Jinrui Guang electricity.
