  • Integrating light source module
    Patent number: 7717599
    Abstract: A light source module is provided comprising an emitter having at least one light emitting surface and an at least partially hollow integrating optic mounted over the emitting surface; where the index of refraction within the hollowed area is less then the index of the subsequent medium along the optical path. The integrating optic has a proximal end facing the emitting surface and a distal end facing away from the emitting surface. The distal end of the integrating optic is flat and has a rectangular aspect ratio which can differ from the aspect ratio of the emitter. One or more optical films and/or an optical component such as a collection lens can be adhered to the distal end of the integrating optic.
