LED lighting development is unstoppable1

The standard issue is one of the topics that LED lighting industry is concerned about. In Tsinghua University Architectural Design and Research Institute Co. , Ltd. , Zhao Jianping, vice president of the Institute of Building environment and energy conservation of the China Academy of Building Sciences and director of the CSA Application Promotion Committee, interpreted the new version of 'building lighting design standards' (GB50034-2013)Provisions on LED lighting in. According to reports, the current standards for lighting design are constantly updating the terms of LED lighting. In addition to 'architectural lighting design standards' (GB50034-2013)In addition, 'urban road lighting design standards' (CJJ45) , 'Stadium lighting design and testing standards' (JGJ153) Under revision, 'technical requirements for LED Indoor lighting application' and 'technical requirements for LED urban road lighting application' have been reviewed. Zhao Jianping said frankly that the reason why the previous lighting designers did not dare to use LED lamps was because there was no standard. It can be seen that with the introduction of a number of lighting design standards for LED products, the application of LED lighting in various places will be fully rolled out. Zhao Jianping said that the new version of 'architectural lighting design standards' (GB50034-2013) The evaluation indexes in include: lighting quantity, lighting quality and lighting energy saving. Its principle is to make lighting products safe, comfortable, energy-saving and environment-friendly. Zhao Jianping emphasized the mandatory standards in the new GB50034 standard, some of which are even higher than those in Europe and America. It is worth noting that in addition to the light efficiency issues that the industry has been paying attention to, the new version of the standard emphasizes several important indicators of lighting comfort. For example, the color tolerance between the selected similar light sources should be less than 5 SDCM; The color rendering index shall not be less than 80, and R9 shall be greater than 0. Especially in a room or place where you work or stay for a long time, the color temperature should not be higher than 4000 K; The deviation between the color coordinate of LED and the initial value during the life period should exceed 0. 007; The color coordinate deviation of LED lamps in different directions should not exceed 0. 004, etc. As a bridge between the project and the owner and between the project and the product, the standard that the designer follows in the lighting design determines the selection of lamps, which is also the concern of LED lamp suppliers. What kind of lamps will the designer choose? Zhao Jianping stressed that LED lighting companies often only provide light efficiency and light distribution curves, while ignoring the mandatory standards specified in the new standard. Designers cannot calculate without the above indicators. In addition to the incomplete product parameters provided by the enterprise, LED lighting products have not yet been standardized, and the classification of products is not conducive to the choice of designers. problems such as uneven product quality still restrict the process of LED lighting penetrating into the room. Although designers are still very cautious about the use of LED lighting in indoor lighting, Zhao Jianping still believes that LED products will spread all over the lighting, and semiconductor lighting is unstoppable in the lighting field. semiconductor Lighting has great potential for energy conservation and emission reduction.
