Abstract

A light-emitting device includes a surface-light-emitting unit, a substrate, a holding sheet, and a sealing sheet. The surface-light-emitting unit has a light-emitting surface and a non-light-emitting surface, and emits light from the light-emitting surface. The substrate has a mounting surface and a non-mounting surface provided to be flush with the light-emitting surface, and has a power source mounted on the mounting surface. The holding sheet is provided to face the non-mounting surface and the light-emitting surface provided to be flush with the non-mounting surface. The sealing sheet is disposed on the side opposite to the holding sheet with respect to the surface-light-emitting unit and the substrate, and provided to cover the surface-light-emitting unit and the power source. The light-emitting device is disposed so that the holding sheet comes to the installation surface side. With such a structure, the light-emitting device that can be stably disposed on the installation surface is provided.

Claims (34)

1. A light-emitting device to be installed on an installation surface, comprising:

a surface-light-emitting unit having a light-emitting surface and a non-light-emitting surface disposed on a back side of the light-emitting surface, and emitting light from the light-emitting surface;

a base member having a first surface and a second surface disposed on a back side of the first surface and provided to be flush with one of the light-emitting surface and the non-light-emitting surface, and having an electronic component mounted on the first surface;

a first sheet provided to face the second surface and one of the light-emitting surface and the non-light-emitting surface that is provided to be flush with the second surface; and

a second sheet disposed on a side opposite to the first sheet with respect to the surface-light-emitting unit and the base member so as to cover the surface-light-emitting unit and the electronic component, wherein the light-emitting device is installed so that the first sheet comes to the installation surface side.

2. The light-emitting device according to claim 1 , wherein the first sheet and the second sheet have flexibility.

3. The light-emitting device according to claim 1 , wherein the surface-light-emitting unit and the base member have flexibility.

4. The light-emitting device according to claim 1 , wherein the electronic component includes at least one of a power source for supplying electric power to the surface-light-emitting unit, a control component for controlling light emission of the surface-light-emitting unit, and a communication component used for external communication.

5. The light-emitting device according to claim 1 , wherein a plurality of the surface-light-emitting units is arrayed in a plane shape between the first sheet and the second sheet.

6. The light-emitting device according to claim 5 , wherein the plurality of surface-light-emitting units includes a first surface-light-emitting unit whose light-emitting surface is flush with the second surface and a second surface-light-emitting unit whose non-light-emitting surface is flush with the second surface.

7. The light-emitting device according to claim 1 , wherein
