Abstract:
1. A device comprising: a side-emitting, none-lasing light emitting diode (LED) die, the LED die comprising: a solid light guide having a top surface through which light is emitted, the light guide having a cavity, of approximate dimensions as the LED die, in which the side-emitting LED die is positioned, whereby light emitted from the sides of the LED die is optically coupled into the light guide; a reflector layer on a bottom surface of the light guide and covering the cavity; a reflector around side walls of the solid light guide; a submount supporting the LED die; a metal support structure, connected to the submount and the light guide, that acts as a heat sink for the LED die; a driver electrically connected to the first electrode and the second electrode of the LED die for supplying power to the led die to illuminate a subject for recording an image of the subject; and a camera, the LED die and driver being mounted within the camera, wherein the first side of the LED die faces the same direction as the top surface of the light guide, and wherein the submount and the metal support structure are located above the top surface of the light guide.
