Patent ID: 7850336

Claim:
A light emitting module comprising: a plurality of point light sources having a first light emitting chip emitting first light, a second light emitting chip emitting second light, and a third light emitting chip emitting third light; and a substrate having the point light sources disposed on the substrate, the substrate applying a driving power to the point light sources, wherein at least one restriction light emitting chip among the first, second and third light emitting chips has a larger light emitting area than a remainder of the light emitting chips, wherein the first, second and third light emitting chips have light emitting intensities of L 1 , L 2 and L 3 per unit power consumption and unit light emitting area, respectively, and the restriction light emitting chip has a largest value among x/L 1 , y/L 2 and z/L 3 , when the first light, the second light and the third light are mixed with a ratio of x:y:z to form white light, and wherein x is a light intensity of the first light with respect to the white light, y is a light intensity of the second light with respect to the white light, and z is a light intensity of the third light with respect to the white light.
