PROBLEM TO BE SOLVED: To provide a light emitting device in which a light source can be placed nearer to a center on a light emitting surface, a structure is simple, and necessary heat radiation can be secured.SOLUTION: A light emitting device includes a plurality of light source units 1 and a unit support plate 2. The plurality of light source units 1 are placed in the way that they surround a shaft of the unit support plate 2. The light source units 1 are provided with a COB light source 5 and a radiator. The radiator is provided with the COB light source 5 on one surface. The radiator is provided on one surface of the unit support plate 2 in the state that the surface is opposite to one surface of the unit support plate 2. Also, the radiator is provided larger in the direction in which it stays away from the shaft from the COB light source 5 than in the direction in which it goes near the shaft from the COB light source 5. |
