在70年代末,我国一些电视台采用过三基色光灯作为电视新闻演播室的照明光源,虽然取得了一定的效果,但是由于灯具体积太大,色温也不一致,色调还原不稳定,工作时有噪音等原因而没有推广起来。 新型三基色柔光灯具是通过改变用于灯内荧光粉物质的配方来控制调整颜色的,它几乎只发出红、绿、兰三基色可见光,而且发出来的光束完全符合电视摄像机所需要的Ra85-95显色指数和3200Lx的照度。
In the late 1970s, some television stations in our country used three primary colors of light as the lighting source for television newsrooms. Although some effects have been achieved, the color of the lamps is too large, the color temperature is inconsistent, the color tone is unstable, and there is noise during work And other reasons not to promote it.
