Abstract
A light emitting device and method for fabricating the device utilizes an adhesive layer of siloxane material to enhance the adhesion of an encapsulant to a light source, one or more leadframes and/or a reflector cup surface. The siloxane layer can be used in different types of light emitting devices, such as lead frame-mounted light emitting diodes (LEDs) and surface mount LEDs with or without reflector cups.
Claims20
A light emitting device comprising:
- a mounting structure having a surface;
- a light source coupled to said surface of said mounting structure;
- an adhesive layer of siloxane material over said light source;
- and
- an encapsulant coupled to said light source via said adhesive layer of siloxane material, said adhesive layer of siloxane material providing adhesion between said encapsulant and said light source.
2 more elements
A method for fabricating a light emitting device with an encapsulant, said method comprising:
- attaching a light source to a surface of a mounting structure;
- forming an adhesive layer of siloxane material over said light source;
- and
- forming said encapsulant over said adhesive layer of siloxane material, said adhesive layer of siloxane material providing adhesion between said encapsulant and said light source.
1 more element
A light emitting device comprising:
- a leadframe having a surface;
- a light emitting diode die attached to said surface of said leadframe;
- an adhesive layer of siloxane material on said light emitting diode die;
- and
- an encapsulant coupled to said light source via said layer of siloxane material, said adhesive layer of siloxane material providing adhesion between said encapsulant and said light emitting diode die.
