Abstract: A light source module includes first and second light sources. The first light source includes a blue light-emitting body emitting blue light and a red fluorescent material disposed around the blue light-emitting body emitting red light by virtue of being excited by the blue light. The second light source is disposed adjacent to the first light source, and includes a green light-emitting body emitting green light. The blue and green light-emitting materials may include a light-emitting diode (LED) chip including substantially the same material. Accordingly, since a variation of light efficiency of the light source module with respect to temperature is small, a color feedback system may be omitted, and color reproducibility may be high.

Abstract translation: 光源模块包括第一和第二光源。 第一光源包括发射蓝光的蓝色发光体和蓝色发光体周围红色荧光材料，蓝色发光体被蓝色光激发而发出红色光。 第二光源与第一光源相邻设置，并且包括发出绿光的绿色发光体。 蓝色和绿色发光材料可以包括基本上相同材料的发光二极管（LED）芯片。 因此，由于光源模块相对于温度的光效率的变化小，因此可以省略颜色反馈系统，并且颜色再现性可能高。
