Wang Guohua is the general manager of Beijing Gaokeeng Optoelectronic Technology Co., Ltd. As an expert in the solar energy industry subsidized by the State Council, he has undertaken 5 national science and technology projects and a national large-scale solar energy project (27 solar power station designs). Research in solar and semiconductor light sources has been around for 10 years. There are 5 patented semiconductor light source technologies and rich practical experience. There are more than 10 professional testing equipment. Install thousands of solar street lights and thousands of small systems. He has represented China for many times at the domestic and international solar industry exhibitions, and won two domestic gold awards and one international silver award.
Wang Guohua as the first inventor developed solar LED street light
This project includes two internationally advanced technologies, solar power generation and semiconductor lighting. The special LED light-emitting tube and driving circuit are selected to produce ultra-high brightness and high-power LED light source, and the power supply adopts solar power generation DC system and battery to form a solar LED street light system. The 20W LED light source is equivalent to the brightness of a 200W incandescent lamp. The light efficiency reaches 27LM/W. The 7-meter-high ground illumination reaches 18-27 LUX for road lighting in small towns and secondary roads. It completely solves the shortcomings of the conventional solar street lamp system that the performance is unreliable due to the use of the inverter, the low temperature start is difficult, and the lamp life is short.
