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 conducto r having a sealed chamber, which has a first portion in the supporting frame and a seco nd portion extended to the heat sink, and a cooling agent contained in the sealed chamb er of the heat conductor, wherein the cooling agent is capable of being vaporized by the he at 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. |
