Abstract

This disclosure discloses a light-emitting device. The light-emitting device comprises: a first electrode part; a second electrode part; a third electrode part, spaced apart from the first electrode part and the second electrode part; and a light-emitting unit partially covering the first electrode part and the second electrode part and fully covering the second electrode part, the light-emitting unit having a conductive structure contacting the second electrode part.

Claims (30)

1. A light-emitting device, comprising:

a carrier having a top surface and a bottom surface;

a first electrode having a first part formed on the top surface, and a second part formed on the bottom surface;

a second electrode having a third part formed on the top surface, wherein the first part and the third part are arranged at two opposite sides of the carrier;

a first light-emitting unit disposed on the top surface and electrically connected to the first electrode; and

a transparent body covering the first part, the second part, the third part and the first light-emitting unit.

2. The light-emitting device of claim 1 , wherein the first part overlaps the second part.

3. The light-emitting device of claim 1 , wherein the carrier comprises a transparent material or a non-transparent material.

4. The light-emitting device of claim 1 , wherein the carrier has a side surface and the first part extends beyond the side surface.

5. The light-emitting device of claim 1 , wherein the first part and the third part are electrically separated from each other when the first light-emitting unit is not disposed on the top surface.

6. The light-emitting device of claim 1 , wherein the second electrode has a fourth part formed on the bottom surface and electrically connected to the third part.

7. The light-emitting device of claim 6 , wherein the transparent body covers the third part and fourth part.

8. The light-emitting device of claim 1 , further comprising a connector electrically and physically connected to the first part and the second part.

9. The light-emitting device of claim 8 , wherein the connector covers a side surface of the carrier.

10. The light-emitting device of claim 8 , wherein the connector is shorter than the first part.

11. The light-emitting device of claim 1 , further comprising a second light-emitting unit, wherein the second light-emitting unit and the first electrode are arranged on opposite sides of the first light-emitting unit.

12. The light-emitting device of claim 1 , wherein the carrier is made of a flexible material.

13. The light-emitting device of claim 1 , wherein the first light-emitting unit comprises a plurality of connecting pads, the plurality of connecting pads is formed on a same side of the first light-emitting unit.

14. The light-emitting device of claim 1 , wherein the first electrode fully covers an end portion of the carrier in a top view.

15. The light-emitting device of claim 1 , wherein the transparent body comprises a wavelength conversion layer.

16. The light-emitting device of claim 1 , wherein the carrier has a side surface devoid of the transparent body.

17. The light-emitting device of claim 1 , wherein when the light-emitting device emits light, the light has a first average correlated color temperature over the top surface and a second average correlated color temperature below the bottom surface, the first average correlated color temperature is larger than the second average correlated color temperature.

18. The light-emitting device of claim 17 , wherein the first average correlated color temperature and the second average correlated color temperature have a difference of not smaller than 50K and not greater than 300K.

19. A light-emitting device, comprising:

a carrier having a top surface and a bottom surface;

a first electrode having a first part formed on the top surface and a second part formed on the bottom surface;

a second electrode having a third part formed on the top surface, wherein the first part and the third part are arranged at two opposite sides of the carrier;

a plurality of light-emitting units disposed on the top surface and electrically connected to the first electrode; and

a wavelength conversion layer covering the first part, the second part, the third part and the plurality of light-emitting units.

20. The light-emitting device of claim of 19 , further comprising a connector electrically and physically connected to the first part and the second part.
