A light emitting module is provided to enable RGB(Red, Green and Blue) light emitting chips of the light emitting module to have light emitting areas suitable for a color mixture rate for light-electricity efficiency and white light, thereby improving light usage efficiency of the light emitting module. Plural point light sources(205) include first to third light emitting chips(R1,G1,B1) for emitting first to third color light. In a substrate(207), the plural point light sources are disposed. The substrate applies driving power to the point light sources. Among the first to third light emitting chips, at least one limit light emitting chip unsatisfying the amount of emitted light necessary for obtaining white light by color mixture with the same condition has a light emitting area larger than the other light emitting chips satisfying the necessary amount of emitted light. |
