Abstract:
1. A lighting device comprising: a light emitting device; a reflective sidewall extending away from the light emitting device; a thermally conductive housing spaced apart from the reflective sidewall, wherein a cavity is defined between the reflective sidewall and the thermally conductive housing; a heat dissipating element that extends into the cavity between the reflective sidewall and the thermally conductive housing, wherein portions of the heat dissipating element are spaced apart from both the reflective sidewall and the thermally conductive housing; and a substrate adjacent the reflective sidewall, wherein the light emitting device is on a surface of the substrate adjacent the reflective sidewall, wherein the heat dissipating element extends into the cavity away from the substrate, and wherein a width of the heat dissipating element increases with increasing distance from the substrate.
