摘要:An illumination device which is capable of radially radiating light generated from a light emitting element (4) while the efficiency of dissipating heat from the light emitting element (4) is improved and in which the utilization efficiency of the light from the light emitting element (4) can be improved. The illumination device includes a light emitting element (4), and a plurality of radially disposed radiation fins (2b1-2b8) for dissipating heat generated by the light emitting element (4). An aperture (2b1c) for allowing light from the light emitting element (4) to pass therethrough is formed between adjacent ones of the radiation fins (2b1,2b2) and a reflection surface (2b1a) for reflecting light which is blocked by the radiation fins (2b1,2b2) when passing through the aperture (2b1c) is formed on a surface of each of the radiation fins (2b1,2b2).
