Number of LED lighting design standards

　　According to reports, about lighting design standards are another update on LED lighting terms. In addition to "architectural lighting design standards" (GB50034-2013), the "city road lighting design standards" (CJJ45), "stadium lighting design and testing standards" (JGJ153) is revising them, "LED indoor lighting applications technical requirements" , "LED city road lighting applications technical requirements" have been completed for review. Zhao Jianping frankly, the reason for the previous lighting designers dare "bold" use LED lamps, because there is no standard.

　　Thus, along with a number of lighting design criteria for the introduction of standardized LED products, LED lighting applications in various places will be fully rolled out.

　　Zhao Jianping said the new "architectural lighting design standards" (GB50034-2013) in the evaluation include: number four lighting, lighting quality, energy-saving lighting, the principle is to make the lighting product safety, comfort, energy saving and environmental protection.

　　Zhao Jianping emphasis on the new mandatory standard GB50034 standard, some performance requirements even higher than in Europe and America.

　　It is noteworthy that, in addition to optical efficiency problems the industry has been concerned about the new standards emphasize a few of the important indicators of lighting comfort. For example, the choice of color tolerance between similar sources should be less than 5SDCM; CRI of not less than 80, R9 should be greater than 0. Especially in long-term or staying room or place, the color temperature is not higher than 4000K; bias LED chromaticity coordinates and the original values ??should be more than the lifetime of 0.007; LED lamps deviation in the chromaticity coordinates of not more than 0.004 different directions and so on.
