Patent ID: 8518027

Claim:
A phototherapy device comprising: a light source; a light emanation block; an outlet end configured to be placed in contact with a person's skin; and a heat exchanger including: a first heat transfer region operatively coupled to the light source for the dissipation of heat from the light source via the first heat transfer region; and a second heat transfer region operatively coupled to the light emanation block for the dissipation of heat from the light emanation block via the second heat transfer region, wherein both the light source and the light emanation block are arranged on a forward side of the heat exchanger along a direction extending from the light source to the outlet end of the device, such that both the first heat transfer region and the second heat transfer region are provided on the forward side of the heat exchanger, and such that both the light source and the light emanation block are arranged between the heat exchanger and the outlet end of the device; and wherein the first heat transfer region and the second heat transfer region are substantially thermally isolated from each other.
