Shijiazhuang: Focus on testing and develop comprehensive semiconductor lighting integration technology demonstration

Taking the opportunity of implementing the key technology innovation project “Semiconductor Lighting High-efficiency White LED Technology”, we will integrate the city's backbone units and enterprise resources to jointly build the Shijiazhuang Semiconductor Lighting R&D Center to provide technical support for industrial development. Establish LED color, light and electricity integrated rapid test system and LED accelerated life test system. Focus on testing, testing for semiconductor lighting applications and major demonstration projects to ensure the smooth implementation of demonstration projects. Specially set up LED street light comparison testing topics, organize LED manufacturers, install, track and test in specific sections, comprehensively carry out comparative testing, excellent selection, improve the overall level of LED street lights, and ensure the effect. In terms of applications, we will actively carry out demonstrations of integrated semiconductor lighting integration technologies such as outdoor roads and indoors. There are more than 30 roads for outdoor applications, including 6 trunk roads with a total investment of more than 80 million yuan. The indoor application investment of 9.1 million yuan, with the Shijiazhuang Science and Technology Center Building as a demonstration project, carried out indoor and outdoor comprehensive semiconductor lighting integration technology demonstration.
