The techniques employed might also help to improve LEDs that produce white light by mixing red, green and blue emitters.
混合的应该是emitters,而不是光线。 其中运用到的技术,可能有助于通过混合红、绿、蓝光源改进发白光的LED。
But in the last decade, researchers have successfully developed LEDs that produce white light comparable or superior to incandescents.
但是在近十年里,研究员们成功研发出的二极管灯,能产生跟白炽灯光一样强或者比白炽灯光更强的白光。
