    • A light source having first and second phosphor-converted component light sources is disclosed. The first component light source includes a first LED that emits light at a first wavelength and a first luminescent conversion material layer that converts light of the first wavelength to light of a first output wavelength, and the second component light source includes a second LED that emits light at a second wavelength and a second luminescent conversion material layer that converts light of the second wavelength to light of a second output wavelength that is different from the first output wavelength. The first and second LEDs are constructed in the same material system, preferably in the same batch of wafers on the fabrication line. A controller generates a current through each of the first and second LEDs that results in the light source generating light that is perceived to be a predetermined color.
    • 公开了具有第一和第二磷光体转换组件光源的光源。 第一分量光源包括发射第一波长的光的第一LED和将第一波长的光转换成第一输出波长的光的第一发光转换材料层,并且第二分量光源包括发射的第二LED 第二波长的光和将第二波长的光转换成与第一输出波长不同的第二输出波长的光的第二发光转换材料层。 第一和第二LED被构造在相同的材料系统中,优选地在制造线上的同一批晶圆中。 控制器通过导致光源产生感知为预定颜色的光的每个第一和第二LED产生电流。
