Portable light with light source module and light source module

摘要

A portable light may comprise: a light body having a light source module disposable in an external opening having a given cross-sectional shape and size for receiving the light source module therein. The light source module may comprise: a light source, a reflector and a heat sink thermally coupled to the light source. The light source module may include a circuit board between the reflector and the heat sink for supporting the light source and being thermally coupled to the heat sink.

1. A portable light comprising:
a light body having a first cavity having a given cross-sectional shape and size and having a second cavity for receiving a source of electrical power therein, the first cavity having an external opening for receiving a light source module therein; an actuator on said light body for controlling energizing a light source for selectively producing light when a source of electrical power is in the second cavity, and a light source module having an exterior of the given cross-sectional shape and size for being placed into the first cavity of said light body, said light source module comprising:
a light source for producing light when energized;a reflector for receiving light from said light source and having a surface for reflecting the light produced by said light source towards an open end of said reflector, wherein said reflector is electrically conductive and provides a first electrical connection to said light source; anda heat sink attached to said reflector and thermally coupled to said light source, wherein said heat sink is electrically conductive and provides a second electrical connection to said light source,wherein said light source, said reflector and said heat sink form an integral module that is insertable into and securable in the first cavity of said light body; and further comprising: a lens covering the open end of said reflector; a lens ring holding said lens adjacent the open end of said reflector; and a pair of electrical contacts on said light body for receiving electrical power from a source of electrical power when a source of electrical power is in the second cavity of said light body, wherein a first of said pair of electrical contacts makes contact with said reflector and a second of said pair of electrical contacts makes contact with said heat sink.
