A lighting device is provided in which a problem caused by heat generation by an LED is resolved, and further size reduction is achieved. n The lighting device includes: a heat radiating part 2 provided with a cavity that accommodates a part of a plurality of drive circuit components 31, 31, 31,... driving a light source module 1; and a base part 5 provided with a cavity 51 that accommodates another part (e.g., a transistor T) of the drive circuit components 31, 31, 31,.... Then, the drive circuit components 31, 31, 31,... are accommodated in the cavity of the heat radiating part 2 and the cavity 51 of the base part 5. |
