Light-emitting device with metallized mounting support structure
View Patent ↗This disclosure discloses a light-emitting device. The light-emitting device has a first outermost sidewall and includes a light-emitting diode and an electrode. The light-emitting diode has a pad and a side surface. The electrode has a segment formed on the pad to extend beyond the side surface, and a first protrusion extending from the segment to the first outermost sidewall.
1. A light-emitting device with a first outermost sidewall and a second outermost sidewall, comprising:
a light-emitting diode, having a side surface and a pad with a bottommost surface in a cross sectional view;
an insulation structure, in the cross sectional view, having an outermost surface and a portion which is directly formed on the bottommost surface; and
an electrode, formed on the portion in a configuration of being electrically connected to the pad, and having a segment, a first protrusion, and a second protrusion,
wherein the segment extends beyond the side surface in the cross sectional view,
wherein in a bottom view, the first protrusion and the second protrusion are formed integrally with the segment, and the first protrusion extended in a first direction from the segment to the first outermost sidewall, and the second protrusion is extended in a second direction from the segment to the second outermost sidewall, and
wherein the segment and the first protrusion are directly formed under the outermost surface.
2. The light-emitting device of claim 1 , wherein the first protrusion is narrower than the segment.
3. The light-emitting device of claim 1 , further comprising a reflective wall overlapping the first protrusion in a direction.
4. The light-emitting device of claim 1 , wherein the pad has an area less than that of the segment.
5. The light-emitting device of claim 1 , wherein the pad is devoid of overlapping the first protrusion.
6. The light-emitting device of claim 1 , wherein the electrode comprises a first layer, and a second layer enclosing the first layer to contact the insulation structure.
7. The light-emitting device of claim 1 , wherein the first protrusion has a width not less than 10 μm.
8. The light-emitting device of claim 1 , wherein the first protrusion and the second protrusion are extended in opposite directions.
9. The light-emitting device of claim 1 , further comprising a wavelength conversion structure enclosing the light-emitting diode.
10. The light-emitting device of claim 9 , wherein the segment overlaps the wavelength conversion structure in a direction.
11. The light-emitting device of claim 1 , wherein the light-emitting diode comprises a plurality of light-emitting bodies electrically connected with each other.
12. The light-emitting device of claim 11 , wherein the light-emitting diode further comprises a trench formed between the plurality of light-emitting bodies.
13. The light-emitting device of claim 1 , wherein the electrode is directly connected to the pad.
14. The light-emitting device of claim 1 , wherein the first protrusion has a surface which is located at a lowermost elevation of the light-emitting device.
15. The light-emitting device of claim 1 , wherein the first protrusion does not extend beyond the first outermost sidewall.
16. The light-emitting device of claim 1 , wherein the first protrusion is made of a metallic material.
17. The light-emitting device of claim 1 , wherein the segment and the first protrusion are formed on a same surface.
18. The light-emitting device of claim 1 , wherein the segment and the first protrusion are made of a same material.
19. The light-emitting device of claim 1 , wherein the second protrusion is formed integrally with the segment and the first protrusion.
