Abstract:
A heat dissipation structure for a light emitting device comprising:a metallic substrate having a top surface and a bottom surface, the top surface configured with a cup-shaped portion for the light emitting device being mounted therein and the bottom surface opposite to the top surface including a metallic solder layer deposited thereon, wherein the cup-shaped portion has an upper surface, an inner surface, and an outer surface, an electrically insulating layer deposited on the upper surface and on the outer surface, an electrically conductive electrode layer deposited on the electrically insulating layer and on the inner surface of the cup-shaped portion, and the electrically conductive electrode layer includes two divided electrodes, the one electrode formed on the inner surface of the cup-shaped portion and the other electrode formed on the upper surface and the outer surface thereof; an electrically insulating fluidic coolant filled in the cup-shaped portion; and a light transparent housing hermetically attached to the metallic substrate to seal the electrically insulating fluidic coolant filled in the cup-shaped portion, the light transparent housing having an inner surface configured with a convex portion opposite to the light emitting device.
