With the advantages of long lifetime, high lighting effect and non-pollution, LED lighting has taken a leading role in the lighting sector. LED street and tunnel lights have no unified product interface, so the products of different enterprises cannot interchange with each other, restraining the development of the whole industry due to the large-scale production problem. The alliance standard CSA 016-2013 has been approved as a national standard project, paving the way for the orderly development of LED industry. Interpreting the CSA 016 standard, the paper expounds on the technical requirements for interchangeable interface in the optical, mechanical, electrical and thermal aspects. 相似文献

The initial growth conditions of a 100 nm thick GaN layer and Mg-surfactant on the quality of the GaN epilayer grown on a 6H-SiC substrate by metal-organic vapor phase epitaxy have been investigated in this research. Experimental results have shown that a high Ⅴ/Ⅲ ratio and the initially low growth rate of the GaN layer are favorable for two-dimension growth and surface morphology of GaN and the formation of a smoother growth surface. Mg-surfactant occurring during GaN growth can reduce the dislocations density of the GaN epilayer but increase the surface RMS, which are attributed to the change of growth mode. 相似文献
