The third phase of '11th five-year plan' 86 lamps enterprise 'LED tunnel road lighting

In the period of '11th five-year plan' 863 project 'half guide light pole production company lighting project', under the support of major projects of guangdong province 'LED tunnel lights' project successfully completed research and development work, recently through the project acceptance. The subject of tunnel lighting and control module

in the period of '11th five-year plan' 863 project 'semiconductor light pole production company main lighting project' under the support of major projects, 'LED tunnel lighting' project research and development of guangdong province has been successfully completed, and through the project acceptance in the near future. This topic of the tunnel lighting and control model, key technology, mass production process and quality guarantee system has carried on the comprehensive study, and made important progress. Through the tunnel under the special light environment lighting photometry and intermediate visual colorimetric model research, the tunnel is proposed considering the comfort and safety of train different sections of led tunnel light and color rendering index, color temperature interval and lamp system of optical design are completed. Its brightness and evenness indexes accord with the requirement of tunnel lighting standards of the state. 24 hours of continuous work for led tunnel lamp and the characteristics of high heat dissipation requirements, invented a new type of transparent empty light-emitting diode cooling plate, effectively solve the mixtures, such as the tunnel dust, exhaust, lampblack pollution of long-term accumulation of the negative impact of the radiator. In addition, aiming at the particularity of tunnel lighting, this topic has built a 50 meters long 1:1 special test tunnel and a set of complete quality testing and performance testing system, including optical, electrical, performance, safety, reliability, etc. For LED tunnel lighting products technology research and development and performance evaluation of the good conditions. Through practical application project, this topic has obtained the good effect of lighting, longitudinal uniformity over 0. 85, total uniformity over 0. After 62, the use of semiconductor lighting energy saving up to 50%. Successful application of this topic, in order to promote the popularization and application of LED tunnel light in our country and promote the 'ten thousands city lights' semiconductor lighting the pilot demonstration of the important technical support.
