ABSTRACT:
The present invention is directed to a light emitting head for use with an electronic camera. The light emitting head is preferably formed as an array of red, green, and blue light emitting diodes (LEDs) provided on the sides of a light guide member, preferably a polygonal prism. A reflecting mirror is arranged on the bottom of the prism, and reflecting elements are provided on the sides of the prism that are not in contact with the LEDs such that, in operation, light from the LEDs is emitted through the top of the prism and prevented from leaking through the sides. A diffusion plate is provided on the emission surface, and the number of green LEDs is larger than the number of red and blue LEDs to produce a white light. In other embodiments, the light guide member is a cylinder or formed entirely as a diffusion plate.
