Abstract
A planar light-emitting device includes a first reflecting surface, a rectangular support disposed adjacent to the first reflecting surface, light sources each including a light-emitting surface and disposed along, at least one side portion of the rectangular support, and a lens including a light-receiving surface disposed to face the light-emitting surfaces of the light sources, and configured to introduce light emitted from the light sources into a space that is demarcated by at least the first reflecting surface and the rectangular support.
Claims21
A planar light-emitting device comprising:
- a first reflecting surface;
- a rectangular support disposed adjacent to the first reflecting surface;
- light sources each including a light-emitting surface and disposed along, at least one side portion of the rectangular support;
- and
- a lens including a light-receiving surface disposed to face the light-emitting surfaces of the light sources, and configured to introduce light emitted from the light sources into a space that is demarcated by at least the first reflecting surface and the rectangular support,
- the rectangular support including a frame shape with an opening that passes through an upper surface and a lower surface of the rectangular support, and including a cut portion that is disposed at and extends along a lower edge of the at least one side portion of the rectangular support.
