The first heat dissipation structure and the second heat dissipation structure may be heat dissipation fins or through holes, and an interval between the heat dissipation fins or through holes of the first heat dissipation structure may be smaller than a distance between the heat dissipation fins or the through holes of the second heat dissipation structure.

According to the above-described configuration, the first light emitting module in the center and the second light emitting module in the side where the generation of heat is concentrated may emit light with a uniform luminous flux value.

As described above, those skilled in the art to which the present invention pertains will understand that the present invention may be implemented in other specific forms without changing the technical spirit or essential features.
