Patent ID: 8778003

Claim:
A skin treatment device for personal use, said device comprising: a means for cooling operatively adapted to create air flow within the device; an optical radiation providing module, wherein the optical radiation providing module comprises: a source of optical radiation; a reflector configured to reflect the emitted optical radiation through at least one dielectric coated protective window, wherein the at least one dielectric coated protective window is located adjacent an open longitudinal section of the reflector and forms with the reflector an air-conducting channel bound on one side by the reflector and on the other side by the dielectric coated protective window, wherein the reflector is an elongated tubular or prismatic case having a curved or polygonal cross section, wherein the reflector is configured to have air passage openings that extend longitudinally down the apex of the reflector located about the apex of the reflector and along the longitudinal axis of said reflector and to allow air flow from the cooling means inside the reflector in a direction substantially perpendicular to the source of optical radiation; air exhaust openings located at the open butt ends of the reflector such that air flow from the cooling means into the air-conducting channel of the reflector provides cooling for the source of optical radiation; and at least one additional window positioned substantially parallel to the at least one dielectric coated protective window such that the at least one additional window is substantially thermally isolated from the at least one dielectric coated protective window, wherein air flow from the cooling means directed in between the at least two parallel windows provides additional thermal isolation; and a means for continuously displacing the device across a segment of skin such that the displacement direction is substantially perpendicular to the direction of the optical radiation reflected through the at least two parallel windows of the optical radiation providing module, wherein the means for continuously displacing monitors the rate of displacement of the device and influences the amount of optical radiation emitted by the optical radiation source.
