Subject: AUTO LED Lighting-太陽光Ra(CRI)值是100
2010-02-05



白光的定義是由兩種顏色以上 混光而成.是兩種以上波長組成-當白光-光源照射到物體上能表現出物體的真實顏色稱為這光源的(演色性)---我們人在生活中無時無刻接觸有各種顏色的物 體.LED的白光-光源照射到物體不能完全表現出物體色彩的真實性-LED白光演色性指數Ra(CRI)值是65~90---意思是LED白光少了一部份 可見光的波長.要能補足這少了的波段.演色性就能提高---太陽光Ra(CRI)值是100-含蓋可見光全光譜.現常用的LED白光少了495~505波 長.要是做到LED演色性指數是80~90在日常生活中已可以.現我們以大量用的日光燈演色性指數是65~85.
