Abstract
A light emitting device includes a support having an interstice and at least one LED located in the interstice and at least one of a waveguide or an optical launch having a transparent material encapsulating the at least one LED located in the interstice.
Claims40
A light emitting device, comprising:
- a light emitting diode (LED) assembly comprising a support having an interstice and at least one LED located in the interstice;
- and
- at least one of a waveguide or an optical launch comprising a transparent material encapsulating the at least one LED located in the interstice.
A method of making a light emitting device, comprising:
- providing a light emitting diode (LED) assembly comprising a support having an interstice and at least one LED located in the interstice;
- and
- encapsulating the at least one LED with a transparent material which forms at least one of a waveguide or an optical launch which at least partially fills the interstice.
An integrated back light unit, comprising:
- a light emitting device assembly comprising a support having an interstice, at least one light emitting device located in the interstice, and an optical launch comprising a transparent material encapsulating the at least one light emitting device located in the interstice;
- and
- a back light waveguide optically coupled to the optical launch, such that the back light waveguide directly contacts the transparent material.
