<P>PROBLEM TO BE SOLVED: To provide a light-emitting diode light source system that provides a longer service life, that is human- and environmental-friendly, and that can improve luminance. <P>SOLUTION: The light-emitting diode light source system according to the present invention includes a plurality of light-emitting diode modules, a light-mixing unit, a plurality of first lens groups, a secondary lens group, and a condensing lens group. The light-emitting diode modules provide fluxes of light. The light-mixing unit includes a plurality of light incident sides and a light emerging side, the light incident sides respectively allowing the fluxes of light from the light-emitting diode modules to be incident thereon. Those fluxes of light emerge from the light emerging side after being mixed. The first lens groups are disposed between each of the light-emitting diode modules and each of the light incident sides. The second lens group is disposed in correspondence with the light emerging side. The condensing lens group is disposed adjacent to the second lens group. By combining the condensing lens group, the first lens groups and the second lens group with each other, the fluxes of light emitted from the light-emitting diode modules and mixed by the light-mixing unit are uniformly projected onto a light bulb. <P>COPYRIGHT: (C)2008,JPO&INPIT |
