Abstract
In described examples, a projector (100) includes a light source (108) to produce first light (106) of a first color. The projector (100) also includes a phosphor (112) to selectively receive the first light (106) and produce second light (102) of a second color in response to the first light (106). The projector (100) also includes a dichroic mirror (153) to pass a portion of the second light (102) to produce a third light (164) of a third color. The dichroic mirror (153) reflects a portion of the second light (102) as fourth light (154) of a fourth color.
