Abstract:
1. A light-emitting diode light source system, comprising: a plurality of light-emitting diode modules for providing light beams; a light-combining unit including a plurality of light incident sides and a light emerging side, the light beams from said light-emitting diode modules entering said light-combining unit via said light incident sides, respectively, and emerging out of said light-combining unit via said light emerging side; a plurality of primary lens units disposed between said light-emitting diode modules and said light incident sides, respectively; a secondary lens unit disposed to confront said light emerging side; and a focusing lens unit disposed adjacent to said secondary lens unit, said secondary lens unit being disposed between said light-combining unit and said focusing lens unit, the light beams from said light-emitting diode modules passing through said primary lens units, said light-combining unit, said secondary lens unit and said focusing lens unit to be projected onto a light valve, wherein each of said light-emitting diode modules includes an array of light-emitting diodes, and a plurality of diode lens caps coupled to said light-emitting diodes, respectively, wherein said array of light-emitting diodes includes a number (n) of light-emitting diodes aligned in a diagonal direction, each of said light-emitting diodes has a diagonal length of (d
