Transparent ring LED assembly
View Patent ↗A substrate for an LED assembly can have a plurality of cups formed therein. At least one cup can be formed within another cup. The cups can be co-axial with respect to one another, for example. A machined surface of the substrate can enhance reflectivity of the LED assembly. A transparent and/or non-global solder mask can enhance reflectivity of the LED assembly. A transparent ring can enhance reflectivity of the LED assembly. By enhancing reflectivity of the LED assembly, the brightness of the LED assembly can be increased. Brighter LED assemblies can be used in applications such as flashlights, displays, and general illumination.
1. An LED assembly comprising:
a transparent ring attached to a substrate, wherein the transparent ring facilitates the formation of at least one layer of material upon at least one LED die by containing the material; and
at least one cup formed in the substrate, wherein the transparent ring is attached to the substrate so as to generally surround the at least one cup.
2. The LED assembly as recited in claim 1 , wherein the transparent ring enhances light emission from the LED assembly.
3. The LED assembly as recited in claim 1 , wherein the transparent ring generally encircles at least one LED die.
4. The LED assembly as recited in claim 1 , wherein the transparent ring facilitates the formation of a silicone layer upon at least one LED die by containing the silicone layer.
5. An LED assembly comprising:
a substrate and a transparent ring attached to the substrate, wherein the transparent ring facilitates the formation of a phosphor layer upon at least one LED die by containing the phosphor layer; and
at least one cup formed in the substrate, wherein the transparent ring is attached to the substrate so as to generally surround the at least one cup.
6. A method for fabricating an LED assembly comprising:
attaching a transparent ring to a substrate, wherein the transparent ring facilitates the formation of at least one layer of material upon at least one LED die by containing the material; and
forming at least one cup in the substrate, wherein the transparent ring is attached to the substrate so as to generally surround the at least one cup.
7. A method for fabricating an LED assembly comprising:
attaching a transparent ring to a substrate, wherein the transparent ring facilitates the formation of at least one layer of material upon at least one LED die by containing the material; and
forming a plurality of generally co-axial cups in the substrate, wherein the transparent ring is attached to the substrate so as to generally surround the plurality of generally co-axial cups.
8. A method for fabricating an LED assembly comprising:
attaching a transparent ring to a substrate, wherein the transparent ring facilitates the formation of at least one layer of material upon at least one LED die by containing the material; and
forming a machined surface upon the substrate, wherein the transparent ring is attached to the substrate so as to generally surround the machined surface of the substrate.
9. The LED assembly as recited in claim 1 , wherein the at least one cup further comprises a plurality of generally co-axial cups formed in the substrate, and wherein the transparent ring is attached to the substrate so as to generally surround the plurality of generally co-axial cups.
10. An LED assembly comprising:
a transparent ring attached to a substrate, wherein the transparent ring facilitates the formation of at least one layer of material upon at least one LED die by containing the material, and
a machined surface formed upon the substrate, wherein the transparent ring is attached to the substrate so as to generally surround the machined surface of the substrate.
