Abstract:
1. A lamp, comprising: a translucent cover; a mounting board on which a semiconductor light-emitting element is mounted; a first housing comprising a metal plate and thermally coupled with the mounting board, the first housing including a first un-covered exterior surface, a second un-covered exterior surface and a third un-covered exterior surface; and a second housing including a power receiving unit configured to receive power for causing the semiconductor light-emitting element to emit light, wherein the first housing is disposed closer to an illuminated area than the second housing is, and wherein the second housing has a thermal conductivity that is lower than a thermal conductivity of the first un-covered exterior surface, wherein a metal bended part of the first housing connects the first un-covered exterior surface and the second un-covered exterior surface, and further connects the first un-covered exterior surface to the third un-covered exterior surface, wherein the second un-covered exterior surface and the third un-covered exterior surface extend parallel to the radial symmetrical center axis of the lamp, wherein the first un-covered exterior surface extends perpendicular to the radial symmetrical center axis of the lamp, wherein the translucent cover is retained by the third un-covered exterior surface such that the translucent covered is closer to the mounting board than the first un-covered exterior surface.
