Abstract

A light-emitting unit, having a substrate; a first light-emitting body formed on the substrate, and having a first longer side and a first shorter side; a second light-emitting body formed on the substrate, and having a second longer side and a second shorter side which is parallel to the first longer side; a third light-emitting body formed on the substrate, having a third longer side and a third shorter side which is parallel to the first longer side, and electrically connected to the first light-emitting body and the second light-emitting body; a first electrode covering the first light-emitting body and the second light-emitting body, and electrically connecting to the first light-emitting body; a second electrode separated from the first electrode, and covering the second light-emitting body without covering the first light-emitting body; and a transparent element enclosing the first light-emitting body, the second light-emitting body, and the third light-emitting body.

Claims (18)

1. A light-emitting unit, comprising:

a substrate;

a first light-emitting body formed on the substrate, and having a first longer side and a first shorter side;

a second light-emitting body formed on the substrate, and having a second longer side and a second shorter side which is parallel to the first longer side;

a third light-emitting body formed on the substrate, having a third longer side and a third shorter side which is parallel to the first longer side, and electrically connected to the first light-emitting body and the second light-emitting body;

a first electrode covering the first light-emitting body and the second light-emitting body, and electrically connecting to the first light-emitting body;

a second electrode separated from the first electrode, and covering the second light-emitting body without covering the first light-emitting body; and

a transparent element enclosing the first light-emitting body, the second light-emitting body, and the third light-emitting body.

2. The light-emitting unit according to claim 1 , wherein the first longer side is larger than the second shorter side.

3. The light-emitting unit according to claim 1 , wherein the second longer side which is parallel to the third longer side.

4. The light-emitting unit according to claim 1 , wherein the first electrode does not cover the third light-emitting body.

5. The light-emitting unit according to claim 1 , wherein the second light-emitting body has a portion not covered by the first electrode.

6. The light-emitting unit according to claim 1 , further comprising a first extension electrode connected to the first electrode and extending beyond the first light-emitting body.

7. The light-emitting unit according to claim 1 , further comprising a second extension electrode connected to the second electrode and extending beyond the second light-emitting body.

8. The light-emitting unit according to claim 6 , wherein the first extension electrode is arranged on the transparent element.

9. The light-emitting unit according to claim 6 , wherein the transparent element has a side surface, the first extension electrode extends to the side surface without extending beyond the side surface.

10. The light-emitting unit according to claim 6 , wherein the first extension electrode has an outer side surface which is not flush with an outer surface of the transparent element.

11. The light-emitting unit according to claim 1 , wherein the transparent element includes epoxy, silicone, or PET.
