  • Publication number: 20050047140
    Abstract: A lighting device composed of a thin LED module has an LED module, a heat sink and a thermally conductive layer clamped between the LED module and the heat sink. The LED module is composed of multiple LED chips densely arranged on a conductive layer in an array without any substrate. By removing the substrate, the lighting device is thin. Additionally, the heat sink is composed of a sealed chamber, vaporable liquid inside the chamber and multiple fins attached to the chamber. Since vaporable liquid transfers heat rapidly and evenly in a gaseous state and the fins increase outside surface areas of the heat sink, the heat sink operates more efficiently, and the lighting device is not easily damaged from accumulated heat.
