Abstract
An illumination device includes a light emitting element, and a plurality of radially disposed radiation fins for dissipating heat generated by the light emitting element. An aperture may be formed between adjacent ones of the radiation fins for allowing light from the light emitting element to pass therethrough. The radiation fins may further include a reflection surface for reflecting light which is blocked by the radiation fins when passing through the aperture.
