Deshida Zou Shenglun: Key Technology and Development Prospect of Solar LED Street Lights

The “2009 PV&LED Technology and Cooperation Forum” held at the Shenzhen Convention and Exhibition Center on October 14 complied with the requirements of industrial development, and discussed the issues and prospects of solar LED lighting in depth, and achieved fruitful results. The forum was held concurrently with the "6th China International Semiconductor Lighting Exhibition and Forum" and the "5th Delis China International Solar Photovoltaic (Shenzhen) Exhibition", which was held by Gaogong LED, Shenzhen Solar Energy Society and National Semiconductor Lighting. Co-sponsored by the Engineering Research and Development and Industry Alliance, it is the first forum in China with the theme of solar LED lighting.

    According to the organizer, the forum invited famous manufacturers such as Philips, 泓昱 Lighting, Destar Optoelectronics, Xiamen Guanyu as guest speakers, Gaogong LED Industry Research Center, Shenzhen Solar Energy Society, Shenzhen Electronic Product Quality Inspection. Industry organizations such as the Center and Shenzhen Street Lamp Management Office also actively support and participate.

    Solar LED lighting involves photovoltaic, LED, battery, intelligent control and other fields. What is the current status and development direction of various technologies? Zou Shenglun, Director of Technical Business of Destar Optoelectronics Technology (Shenzhen) Co., Ltd. gave the company's opinion. He believes that the current main application products are solar street lights, garden lights, solar black light insecticidal lamps, solar traffic lights, etc. Building integrated photovoltaic products have been favored by more and more people because of their aesthetic value and price advantage.

    The existing solar energy systems include solar outdoor lighting systems, grid-connected power generation systems, wind-solar complementary systems, and solar-powered telecommunications systems. Zou Shenglun lists the characteristics and key technologies of each system. Zou Shenglun believes that the shortening of battery life is due to the corrosion of the grid by sulfuric acid, external corrosion increases the interconnect resistance, excessive gassing will cause electrolyte loss and plate loss.

    For urban solar applications, Zou Shenglun believes that the following applications can be focused on: the plaza landscape grid-connected system provides lighting power, rain-proof grid-connected solar bus stations, and solar parking lots.
