Abstract
Official abstract text for this publication.
An illumination light source includes a light emitting module having a light emitting part, a circuit unit, a base, a tube-like first housing member to accommodate the circuit unit, and a second housing member having a plurality of radiation fins. The light emitting module is disposed on one opening-side of the first housing member, while the base is disposed on the other opening-side. The second housing member includes a rotary ring body with a rotation axis agreeing with the center axis of the first housing member, and the plurality of the plate-lake radiation fins. The plurality of the radiation fins is parallel to one virtual plane containing the rotation axis, and disposed at intervals between each other in the direction orthogonal to the virtual plane. The inner wall of the rotary ring body surrounds the outer walls of the first and second housing members to combine the members.
