Abstract
A light source includes a light head and a heat transfer arrangement. The light head includes a tubular supporting frame, which has an interior space, and a luminary unit provided on the supporting frame. The heat transfer arrangement, for dissipating heat generated from the light head, includes a heat sink and a heat conductor having a sealed chamber, which has a first portion in the supporting frame and a second portion extended to the heat sink, and a cooling agent contained in the sealed chamber of the heat conductor, wherein the cooling agent is capable of being vaporized by the heat of the luminary unit and condensed by said heat sink so as to substantially enable the heat to flow from the luminary unit towards the heat sink.
Claims20
A light source, comprising:
- a heat transfer arrangement, which comprises a tubular heat conductor having a sealed chamber and a peripheral surface, a heat sink thermally communicating with said heat conductor and a liquid cooling agent contained in said sealed chamber of said heat conductor;
- and
- a light head which comprises a circuit provided on said peripheral surface of said heat conductor and one or more diodes provided on said peripheral surface of said heat conductor to electrically connect with said circuit for emitting light in an outwardly radial direction of said light head, wherein said heat transfer arrangement is adapted for dissipating heat generated from said light head that said cooling agent is capable of transferring said heat away from said diode to said heat sink so as to maintain a predetermined temperature of said light head during operation.
