Abstract:
1. A cooling system for a light emitting device including a light emitting body, comprising: a hermetically sealed space in which air is contained and the light emitting device is housed, the hermetically sealed space defined by a heat dissipation member and a cover film having a double-layered structure fixed to the heat dissipation member; a cooling element disposed in contact with the heat dissipation member in the hermetically sealed space, the cooling element having a heat absorbing surface for absorbing heat from the light emitting device and a heat dissipating surface that is in contact with the heat dissipation member to dissipate the heat absorbed by the heat absorbing surface through the heat dissipation member; and a metal plate disposed between the light emitting device and the cooling element, one surface of which is in contact with the heat absorbing surface of the cooling element and the other surface of which is in contact with the light emitting device, wherein the cover film comprises a transparent resin film located outside the hermetically sealed space, and a metal film located inside the hermetically sealed space and including an opening for exposing a light exit surface of the light emitting body to the outside through the resin film.
