1. An illumination device, comprising:
- a light emitting element;
a plurality of radiation fins located adjacent the light emitting element and configured to dissipate heat generated by the light emitting element, the radiation fins being radially disposed about the light emitting element, whereinan aperture is located between adjacent ones of the radiation fins and is configured to allow light from the light emitting element to pass therethrough, and the radiation fins include a reflection surface configured to reflect light which is incident thereon,the plurality of radiation fins are disposed radially outside of the light emitting element; and
a first bridge structure configured to bridge the plurality of radiation fins, the first bridge structure including a reflection surface configured to reflect light which is incident thereon, the first bridge structure reflecting surface configured to face the plurality of radiation fins.

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.
