LED carrier and LED package having the same
A LED carrier includes a substrate, a conductive layer, an adhesive layer, and a reflector. The conductive layer is disposed on the substrate, and has a bonding portion and an extending portion. The bonding portion has a top surface higher than a top surface of the extending portion. The adhesive layer covers the extending portion of the conductive layer and exposes the bonding portion of the conductive layer. The reflector is disposed over the adhesive layer. The adhesive layer has a hook portion in contact with a corner of the reflector.
1. A LED carrier, comprising:
a substrate;
a conductive layer disposed on the substrate, the conductive layer having a bonding portion, the bonding portion having a top surface that is higher than a top surface of an extending portion of the conductive layer;
an adhesive layer covering the extending portion of the conductive layer and exposing the bonding portion of the conductive layer; and
a reflector disposed over the adhesive layer, wherein the adhesive layer has a hook portion in contact with a corner of the reflector;
wherein the corner of the reflector defines an opening, and the bonding portion passes through the opening, wherein the reflector has an inclined inner surface surrounding the opening, and the hook portion extends through the opening and contacts the inner surface.
2. The LED carrier of claim 1 , wherein the reflector has a bottom surface surrounding the opening, and the hook portion is in contact with the bottom surface.
3. The LED carrier of claim 1 , wherein the hook portion wraps the corner of the reflector.
4. The LED carrier of claim 3 , wherein the reflector has a block located at the corner.
5. The LED carrier of claim 3 , wherein the corner has a side surface perpendicular to a bottom surface of the reflector.
6. The LED carrier of claim 3 , wherein the corner of the reflector has a rounded shape.
7. The LED carrier of claim 1 , wherein the hook portion is formed with an angle matching an angle of the corner.
8. The LED carrier of claim 1 , wherein the hook portion fills a gap between the bonding portion and the reflector.
9. A LED package, comprising:
the LED carrier of claim 1 ; and
a LED chip disposed on the bonding portion and electrically coupled to the bonding portion.
10. The LED package of claim 9 , wherein the bonding portion is geometrically similar to the LED chip.
11. The LED package of claim 9 , further comprising a bonding wire, wherein the LED chip is electrically coupled to the bonding portion by the bonding wire.
12. The LED package of claim 9 , wherein the bonding portion has a greater area than the LED chip in a top viewpoint.
