Patent ID: 8540702

Claim:
A dermatologic treatment device, the device comprising: a light source emitting optical radiation having at least a first set of wavelengths and a second set of wavelengths, the first set of wavelengths being preferred for a dermatologic treatment; a first reflector arranged in a tubular shape, spatially separated from and substantially surrounding the light source, the first reflector reflecting some of the optical radiation exhibiting the second set of wavelengths back to the light source to enhance a brightness of the light source while allowing the optical radiation exhibiting the first set of wavelengths to pass; a thermally conductive material disposed at least between and in thermal communication with the light source and the first reflector, the thermally conductive material facilitating a transfer of heat from the light source to the first reflector; and a contact element in contact with a skin surface, at least some enhanced optical radiation from the-light source being conveyed through the contact element to facilitate the dermatologic treatment; a contact sensor detecting contact between the contact element and the skin surface during the dermatologic treatment, the contact sensor enabling the light source to be energized in response to such detection; and a handheld housing including a removable cartridge, the removable cartridge containing the light source, the thermally conductive material, and the first reflector.
