Paper Abstract
A module of laser-phosphor based light source, wherein phosphor light pumped by laser is combined with blue laser
light to form white light, is used as light source for 3-chip projectors. Arrays of blue laser diodes are concentrated and
aligned by stripes of mirrors and formed into a laser bank. Laser lights of 445nm and 460 nm from two directions and
two half apertures are guided and converged into either red or green phosphors. Red and green lights emerge from two
spots of phosphors are collimated into two directions and reflected into one direction by two dichroic plates. Two
dichroic plates also reflect two directions of 445nm and 460 nm residual blue laser lights into one direction. The
combined red, blue and green lights are guided into one direction and can be used as input light source for 3-chip
projector.
