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.
