  • Patent number: 7401945
    Abstract: A light source arrangement includes an electric input adapter for electrically connecting with a power source and a light head including a supporting frame and a luminary unit. The supporting frame has a dissipating end and a peripheral surface provided thereon. The luminary unit includes a circuit board provided on the peripheral surface of the supporting frame and electrically connected with the electric input adapter, and at least a luminary element, having two terminal electrodes, which is supported by the supporting frame and electrically connected to the circuit board for emitting light when the terminal electrodes are electrified. Therefore, the heat generated by the luminary element directly dissipates at the dissipating end of the supporting frame so as to prevent the light head from overheating.

  • Patent number: 6880956
    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.

  • Patent number: 6578998
    Abstract: A light source arrangement includes a cell body having a concave light projecting surface and a semi-spherical reflective cavity surrounded by the light projecting surface, a light source unit including at least two terminal electrodes extended therefrom and at least a luminary element for emitting light when the terminal electrodes are electrified, and a supporting frame having a predetermined width mounted on the cell body to support the light source unit at a focus point of the reflective cavity in such a manner lights emitted from the light source unit are accumulatively collected and reflected by the reflective cavity to outside. Heat is efficiently dissipated by the supporting frame when a larger current is applied to the light source arrangement. Therefore, up to five luminary elements are adapted to be supported in the light source unit for increasing the light intensity of the light source arrangement.
