Abstract
A color-adjustable medical headlamp assembly, including a headband assembly and a bezel, which can be worn around a user's head. The bezel contains a light source assembly that is capable of generating light with different colors and intensities, and an optical train that focuses the light generated by the light source assembly. A user input assembly is included to allow for the selection and adjustment of both the color and brightness of the light from the bezel. Also, the rear surface of the bezel has a higher coefficient of thermal conductance compared to the movable portion of the bezel and is an avenue for heat dissipation. Finally, a heat shield is attached to the bezel to cover its rear surface, which can pose a burn hazard after prolonged usage.
