Abstract

In a surface light-emitting unit, a wiring board ( 60 ) includes, on its side on which a holding substrate ( 11 ) is located, an external-wire connecting portion ( 40 ). An opening ( 11 h ) is provided in the holding substrate ( 11 ). The wiring board ( 60 ) is disposed to cover the opening ( 11 h ) and allow the external-wire connecting portion ( 40 ) to be exposed, through the opening ( 11 h ), toward a surface of the holding substrate ( 11 ) opposite to the surface thereof on which the wiring board ( 60 ) is held. With an external wire connected to the external-wire connecting portion ( 40 ), a surface of the wiring board ( 60 ) located in the opening ( 11 h ) is sealed by a second sealing member.

Claims (14)

1. A surface light-emitting unit comprising:

a surface light-emitting device;

a holding substrate having a first surface facing a light-emitting surface of the surface light-emitting device, and transmitting light emitted from the surface light-emitting device through a second surface opposite said first surface;

a wiring board located on said first surface of the holding substrate, and electrically connected to the surface light-emitting device;

a first sealing member sealing the surface light-emitting device and the wiring board on the holding substrate;

the wiring board including an external-wire connecting portion on a side of the wiring board on which the holding substrate is located;

an opening formed in the holding substrate;

the wiring board being disposed to cover the opening and allow the external-wire connecting portion to be exposed, through the opening, toward said second surface of the holding substrate;

with an external wire connected to the external-wire connecting portion, a surface of the wiring board that is located in the opening is sealed by a second sealing member, and

wherein the wiring board includes a drive control unit.

2. The surface light-emitting unit according to claim 1 , wherein the wiring board includes a rectifying circuit unit.

3. The surface light-emitting unit according to claim 1 , wherein a flexible material is used for the holding substrate.

4. The surface light-emitting unit according to claim 1 , wherein the surface light-emitting device includes an organic EL device.

5. The surface light-emitting unit according to claim 1 , wherein the surface light-emitting device, the wiring board, and the external-wire connecting portion are all sealed by the holding substrate, the first sealing member, and the second sealing member.
