Abstract
Solid state lighting (SSL) devices with good color uniformity and methods of manufacturing are disclosed herein. In one embodiment, an SSL device includes a support structure, an SSL die in the support structure, and a converter material at least partially encapsulating the SSL die. The converter material is configured to emit under excitation. The converter material has a surface facing away from the SSL die, and the surface of the converter material has a generally convex shape.
Claims23
A solid state lighting (SSL) device, comprising:
- a support structure;
- an SSL die in the support structure;
- and
- a converter material at least partially encapsulating the SSL die, the converter material having a surface facing away from the SSL die, wherein the surface of the converter material has a shape configured with respect to at least one of a shape and a size of the SSL die such that an angular difference in optical path length in the converter material is below a predetermined threshold.
A solid state lighting (SSL) device, comprising:
- a support structure;
- an SSL die in the support structure;
- and
- a converter material at least partially encapsulating the SSL die, the converter material being configured to emit under photoluminescence, the converter material having a surface facing away from the SSL die, wherein the surface of the converter material has a generally convex shape.
A method for forming a solid state lighting (SSL) assembly, comprising:
- placing an SSL die in a support structure;
- at least partially encapsulating the SSL die with a converter material, the converter material being configured to emit under photoluminescence;
- and
- forming a surface of the converter material based on at least one of a shape and size of the SSL die such that an angular difference in optical path length in the converter material is below a predetermined threshold.
