Abstract
A planar illumination device according to an embodiment comprises a substrate, a plurality of light sources in a first group, and one or more light sources in a second group. Prescribed electrical wiring is applied to the substrate. The plurality of light sources in the first group are disposed across substantially the entire surface of the substrate. The one or more light sources in the second group are disposed adjacent to the plurality of light sources in the first group within a prescribed region on the substrate.
Claims10
A planar illumination device comprising:
- a substrate;
- a plurality of first light sources disposed in a first region of the substrate;
- and
- one or more second light sources disposed at a position different from the first light sources in a second region within the first region.
A planar illumination device comprising:
- a substrate;
- a plurality of light sources of a first group disposed across substantially an entire surface of the substrate;
- one or more light sources of a second group disposed adjacent to the plurality of light sources of the first group in a predetermined region of the substrate;
- and
- a reflector including reflecting walls surrounding each of the plurality of light sources of the first group, wherein
- the plurality of light sources of the first group are disposed in a grid form across substantially the entire surface of the substrate,
- a light source of the second group is disposed at a center of four of the light sources of the first group vertically and horizontally adjacent to each other, and
- at least part of four of the reflecting walls between the four light sources of the first group, with the light source of the second group disposed at the center, is removed.
