Abstract
There is provided an illuminating device. The illuminating device includes a light source unit including a substrate and one or more light emitting devices mounted on the substrate, and a heat radiating unit including a sealed inner space into which a working fluid is injected, the working fluid being evaporated and condensed within the inner space due to heat of the light source unit, and emitting the heat of the light source unit to the outside through repeated phase changes according to evaporation and condensation of the working fluid.
Claims11
An illuminating device, comprising:
- a light source unit including a substrate and one or more light emitting devices disposed on the substrate;
- and
- a heat radiating unit including a sealed inner space into which a working fluid is injected, the sealed inner space having a center hole penetrating the sealed inner space, the working fluid being evaporated and condensed within the inner space due to heat of the light source unit, such that the heat radiating unit emits the heat of the light source unit to the outside through repeated phase changes according to evaporation and condensation of the working fluid.
An illuminating device, comprising:
- a light source unit including a substrate and one or more light emitting devices disposed on the substrate;
- and
- a heat radiating unit including a sealed inner space into which a working fluid is injected, the working fluid being evaporated and condensed within the inner space due to heat of the light source unit, and emitting the heat of the light source unit to the outside through repeated phase changes according to evaporation and condensation of the working fluid, wherein:
- the heat radiating unit further includes:
- a heat absorbing surface having the light source unit disposed thereon;
- an inner side surface having one end connected to the heat absorbing surface and the other end extending upwardly from the heat absorbing surface;
- and
- a heat radiating surface connecting the other end of the inner side surface with an outer circumference of the heat absorbing surface, and
- the heat radiating unit is a structure which has a triangular cross sectional shape in which the heat radiating surface forms an inclined plane, based on the heat absorbing surface used as a bottom surface.
