Summary The full technical content of this recommended technical specification is recommended. The purpose of this recommended technical specification is to guide the design, production and use of LED tunnel lights, to standardize and guide the application and development of LED tunnel lighting technology. This recommended technical specification can be used in the “Ten Cities and Ten Thousand†pilot demonstration project. This recommended technical specification is an interim draft. The evaluation items and technical indicators involved are the most basic and have good assessment and operability. For the time being, they do not pursue comprehensiveness and integrity, and will follow the LED tunnel lighting product technology. The level of continuous improvement and the corresponding level of technical standardization continue to improve, for further revision. This recommended technical specification was proposed by the National Semiconductor Lighting Engineering R&D and Industry Alliance. This recommended technical specification is mainly drafted by: Fudan University, Shanghai Yangtze River Tunnel Construction Development Co., Ltd., Beijing Semiconductor Lighting Technology Promotion Center, National Lighting Quality Supervision and Inspection Center, National Electric Light Source Quality Supervision and Inspection Center (Beijing), National Electric Light Source Quality Supervision and Inspection Center (Shanghai), Zhejiang University, Hangzhou Yuanfang Optoelectronic Information Co., Ltd., Shanghai Tunnel Engineering Rail Transit Design and Research Institute, Chongqing Transportation Research and Design Institute, Guangdong Zhonglong Transportation Technology Co., Ltd., Dongguan Qinshang Optoelectronics Co., Ltd., Nanjing Henderson Technology Co., Ltd., Jiangsu Shifu Photoelectric Technology Co., Ltd., Shenzhen Bangbeier Electronics Co., Ltd., Shanghai Sansi Technology Development Co., Ltd.
