Abstract
In described examples, a projector includes a light source to produce first light of a first color. The projector also includes a phosphor to selectively receive the first light and produce second light of a second color in response to the first light. The projector also includes a dichroic mirror to pass a portion of the second light to produce a third light of a third color. The dichroic mirror reflects a portion of the second light as fourth light of a fourth color.
