Claim 5:
6. A laser phosphor projection system, comprising:
a) a plate having a first side, a second side opposite the first side, and a hole therethrough;
b) a first plurality of laser diodes arranged on the first side of the plate to generate a first set of blue light rays;
c) a concave reflector having a focal point, the concave reflector positioned to receive the first set of blue light rays emitted from the first plurality of laser diodes and reflect the first set of blue light rays toward the focal point, wherein the focal point is at the hole of the plate;
d) a directing lens located at the hole of the plate through which the first set of blue light rays reflected off of the concave reflector passes to direct the first set of blue light rays as a first beam of blue light;
e) a phosphor target having a first side and a second side, wherein the phosphor target is positioned to receive the first beam of blue light and emit broad band light rays;
f) a collection lens to collect the broad band light rays and direct the collected broad band light rays as a beam of broad band light; and
g) an optical device positioned to reflect the beam of broad band light to into a projector imaging device.
