在建筑照明领域,选用LED灯应符合下列条件:显色指数Ra不应低于80,同类光源的色容差不应超过5 SDCM,特殊显色指数R9>0,色温不宜高于4 000 K,寿命期内的色偏差不应超过0.007,不同方向的色偏差不应超过0.004;灯具宜有漫射罩,灯的谐波应符合国标GB 17625.1—2012的规定,灯的功率因数不宜小于0.9,灯的使用寿命和光通维持率应符合GB/T 24908—2014的规定。最后,对设计标准GB 50034—2013和产品标准GB/T 24908—2014中关于LED灯的技术要求进行了比较。
In the field of architectural lighting, the selection of LED lamps should meet the following conditions: color rendering index Ra should not be less than 80, the same color light source color tolerance should not exceed 5 SDCM, special color rendering index R9> 0, the color temperature should not be higher than 4 000 K , The color deviation during the life should not exceed 0.007, the color deviation in different directions should not exceed 0.004; lamps should diffuse cover, lamp harmonics should be consistent with the provisions of GB GB 17625.1-2012, the lamp power factor should not be less than 0.9 , Lamp life and lumen maintenance should be consistent with the provisions of GB / T 24908-2014. Finally, the design requirements of the standard GB 50034-2013 and product standards GB / T 24908-2014 LED lamp on the technical requirements were compared.
