| 摘要 |
The invention includes a color projection system. System includes a light source, a first relay lens, disposed on a first optical path, optically coupled to the light source. System also includes a second relay lens, disposed in a second optical path, optically coupled to the first lens, the second optical path being of a predetermined vertical distance above the first optical path. The color projection system also includes a light management device, having a light entrance surface and a light exit surface, the light entrance surface optically coupled to the second lens along the second optical path, the light exit surface located on a third optical path, and the third optical path being substantially parallel to the first and second optical paths and being a predetermined distance below the second optical path. A projection lens may be optically coupled to the light exit surface of the light management device.
