Abstract

A light-emitting device ( 100 ) includes a housing ( 20 ) including a light-transmitting section ( 25 ), a surface light-emitting element ( 10 ) including a rectangular light-emitting section (R 10 ) facing the light-transmitting section ( 25 ) and a non-light-emitting section formed outside the light-emitting section (R 10 ), and an electronic device ( 31 ). The non-light-emitting section includes a flexible outer edge section (R 13 ) provided with an electrode on a surface. The outer edge section (R 13 ) is bent in a direction away from a light-emitting surface (S 1 ) of the light-emitting section (R 10 ) together with the electrode. The electrode electrically connects the light-emitting section (R 10 ) and the electronic device ( 31 ).

Claims (42)

1. A light-emitting device comprising:

a housing including a light-transmitting section;

a surface light-emitting element arranged in the housing, and including a rectangular light-emitting section facing the light-transmitting section, and a non-light-emitting section formed outside the light-emitting section; and

an electronic device arranged in the housing, wherein

the non-light-emitting section includes a flexible outer edge section provided with an electrode on a surface,

the outer edge section is bent in a direction away from a light-emitting surface of the light-emitting section together with the electrode, and

the electrode electrically connects the light-emitting section and the electronic device,

wherein the electrode includes at least either one of an anode electrode and a cathode electrode.

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

the light-emitting section has flexibility, and is bent along a shape of an inner peripheral surface of the light-transmitting section.

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

the outer edge section includes a first outer edge section provided with the anode electrode, and a second outer edge section provided with the cathode electrode.

4. The light-emitting device according to claim 3 , wherein

another cathode electrode is further provided on the first outer edge section, and

another anode electrode is further provided on the second outer edge section.

5. The light-emitting device according to claim 3 , wherein

the first outer edge section and the second outer edge section are positioned at mutually opposite sides across the light-emitting section.

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

the outer edge section includes at least one first fixing section in a portion where the electrode is not provided, the portion being of the surface of the outer edge section, and

the outer edge section is fixed to the housing through the first fixing section.

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

the outer edge section includes at least one second fixing section in a portion where the electrode is provided, the portion being of the surface of the outer edge section, and

the electrode is electrically connected to the electronic device, by the outer edge section being fixed to the electronic device through the second fixing section.

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

the outer edge section is formed integrated with the surface light-emitting element.

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

the surface light-emitting element includes a transparent substrate, and the outer edge section is a part of the transparent substrate.

10. A surface light-emitting element comprising:

a rectangular light-emitting section; and

a non-light-emitting section formed outside the light-emitting section, wherein

the non-light-emitting section includes a flexible outer edge section, and

an electrode that electrically connects the light-emitting section and an electronic device is provided on a surface of the outer edge section in a state of being bent in a direction away from a light-emitting surface of the light-emitting section together with the outer edge section,

wherein

the electrode includes at least either one of an anode electrode and a cathode electrode.

11. The surface light-emitting element according to claim 10 , wherein

the outer edge section includes a first outer edge section provided with the anode electrode, and a second outer edge section provided with the cathode electrode.

12. The surface light-emitting element according to claim 11 , wherein

another cathode electrode is further provided on the first outer edge section, and

another anode electrode is further provided on the second outer edge section.

13. The surface light-emitting element according to claim 11 , wherein the first outer edge section and the second outer edge section are positioned at mutually opposite sides across the light-emitting section.

14. The surface light-emitting element according to claim 10 , wherein

the surface light-emitting element includes a transparent substrate, and the outer edge section is a part of the transparent substrate.
