description | Backlighting systems are disclosed, which include a lightguide with at least one light source optically connected to an edge of the lightguide for supplying light into its interior and a reflective cavity with at least one light source optically connected to the reflective cavity for supplying light into its interior. The reflective cavity may include a first reflector and a second reflector and at least one source may be disposed at an edge of the reflective cavity. Alternatively, the reflective cavity may include a back reflector portion and light sources may be disposed at the back reflector portion. |
