Abstract: An illumination device that can obtain high withstanding voltage performance while making heat transfer to a casing from a light-emitting element favorable is provided. In a sports illumination device including a COB type LED as a light source in a casing, a base plate that has the COB type LED mounted thereon and is formed from a high thermoconductive material, to which heat of the COB type LED is transferred, is included, the casing is provided with an engaging hole with which the base plate is engaged in a state in which a part of the base plate is exposed outside the casing, and an insulation packing is provided at a site of contact of the base plate and the engaging hole in the casing.

Abstract: A lamp achieves high output power like an HID lamp by using a light emitting element(s) as a light source. A mount board having LED mounted thereon is provided on the surface of a base member, and there are provided plural flat plate type light source units arranged around an axial line while the back surfaces thereof faces inwards, and a support member provided on the axial line. The plural light source units are supported on the support member, and a space through which air flows is provided at the back surface side of each base member.
