Abstract
A light source that utilizes light emitting diodes that emit white light is disclosed. The diodes are mounted on an elongate member having at least two surfaces upon which the light emitting diodes are mounted. The elongate member is thermally conductive and is utilized to cool the light emitting diodes. In the illustrative embodiment, the elongate member is a tubular member through which a heat transfer medium flows.
Claims23
A light source comprising:
- an elongate thermally conductive member having an outer surface;
- at least one light emitting diodes carried on said elongate member outer surface;
- one or more electrical conductors carried by said elongate thermally conductive member and connected to said at least one light emitting diodes to supply electrical power thereto;
- and
- said elongate thermally conductive member being configured to conduct heat away from said at least one light emitting diode to fluid contained by said elongate thermally conductive member.
2 more elements
A light source comprising:
- an elongate thermally conductive member having an outer surface;
- a plurality of light emitting diodes carried on said elongate member outer surface at least some of said light emitting diodes being disposed in a first plane and others of said light emitting diodes being disposed in a second plane not coextensive with said first plane;
- electrical conductors carried by said elongate thermally conductive member and connected to said plurality of light emitting diodes to supply electrical power thereto;
- and
- said elongate thermally conductive member being configured to conduct heat away from said light emitting diodes to fluid contained by said elongate thermally conductive member.
