A light source[30, 50, 70, 90, 100, 110] and a display utilizing the same are disclosed. The light source[30, 50, 70, 90, 100, 110] includes a laser, a light pipe[32, 52, 60, 92, 106], and an optical fiber. The light pipe[32, 52, 60, 92, 106] includes a layer of transparent material having a top surface[21], a bottom surface[41], and a first edge[36]. The first optical fiber[35, 104] couples light from the laser to the first edge[36] at a first location. The light is injected into the light pipe[32, 52, 60, 92, 106] such that the light is reflected from the top surface[21] and the light pipe[32, 52, 60, 92, 106] includes a plurality of scattering centers[40] that scatter the light through the top surface[21]. The laser can be in thermal contact with a heat sink[34, 75, 119, 105] placed at a location that is adapted for dissipating heat. The light source[30, 50, 70, 90, 100, 110] can include a plurality of lasers in a color display. The light from the various lasers can be mixed before it reaches the light pipe[32, 52, 60, 92, 106] or in the light pipe[32, 52, 60, 92, 106]. |
