Abstract:
An optical fixing device includes light source fixing parts for fixing a plurality of solid state light sources, a second light combination element fixing part for fixing at least one second light combination element, a condenser lens fixing part for fixing a condenser lens, and second reflecting mirror fixing parts arranged in accordance with at least part of the plurality of solid state light sources for fixing second reflecting mirrors. The second light combination elements are used for transmitting some light emitted from the solid state light sources and is not reflected and/or are used for reflecting light reflected by the second reflecting mirrors. The condenser lens is used for converging the light passing through the second light combination elements. The optical fixing device is compact in size and shape with low production cost, providing high accuracy for the relative positioning of the optical elements.
