Abstract

Solid state lighting (SSL) devices including a plurality of SSL emitters and methods for manufacturing SSL devices are disclosed. Several embodiments of SSL devices in accordance with the technology include a support having a first lead and a second lead, a plurality of individual SSL emitters attached to the support, and a plurality of lenses. Each SSL emitter has a first contact electrically coupled to the first lead of the support and a second contact electrically coupled to the second lead of the support such that the SSL emitters are commonly connected. Each lens has a curved surface and is aligned with a single corresponding SSL emitter.

Claims (24)

1. A solid state lighting (SSL) device, comprising:

a support having a first lead and a second lead;

a plurality of individual SSL emitters attached to the support, wherein each SSL emitter has a first contact electrically coupled to the first lead of the support and a second contact electrically coupled to the second lead of the support such that the SSL emitters are commonly connected;

a plurality of lenses having a transparent material and a converter material distributed in the transparent material, wherein each lens has a curved surface and is aligned with a single corresponding SSL emitter; and

wherein the lenses are arranged such that each lens contacts an adjacent lens.

2. The SSL device of claim 1 , wherein:

the support has a plurality of mounting sites and each mounting site has an anodic contact electrically coupled to the first lead and a cathodic contact electrically coupled to the second lead;

the SSL emitters are light emitting diodes (LEDs) that emit light at substantially the same wavelength; and

each lens has a center aligned with a center of a corresponding LED.

3. The SSL device of claim 1 , wherein the converter material comprises a phosphor selected to emit a desired color of light such that light from the SSL emitters and the light from the phosphor combine to create a desired color.

4. The SSL device of claim 1 , wherein the support comprises a substrate including a plurality of depressions, and wherein each SSL emitter is positioned in a corresponding depression.

5. The SSL device of claim 4 , wherein the substrate comprises a metal substrate and the SSL emitters have contacts surface mounted to the metal substrate.

6. A solid state lighting (SSL) device, comprising:

a support;

a plurality of SSL emitters attached to the support, wherein the SSL emitters act as point sources that each emit a point light at a first frequency;

a plurality of lenses arranged relative to the SSL emitters such that each lens is aligned with a single one of the SSL emitters in a lens-emitter pair, wherein each lens has a curved surface, and wherein each lens and corresponding SSL emitter of a lens-emitter pair are configured such that all point light from the SSL emitter passes through the curved surface of the corresponding lens; and

wherein each lens contains a transparent material and a converter material distributed in the transparent material, wherein the converter material emits light at a second frequency different than the first frequency; and

wherein the lenses are arranged such that each lens contacts an adjacent lens.

7. The SSL device of claim 6 , wherein:

the support has a first lead configured to be coupled to a first potential of a power supply and a second lead configured to be coupled to a second potential of the power supply; and

the SSL emitters each have a first contact electrically coupled to the first lead and a second contact electrically coupled to the second lead such that all of the SSL emitters are configured to be commonly connected to the power supply.

8. The SSL device of claim 6 , wherein the SSL emitters comprise LEDs.

9. The SSL device of claim 6 , wherein the support comprises a metal support having depressions, each depression is sized and shaped to receive one of the SSL emitters, and each SSL emitter is received in a depression.

10. The SSL device of claim 6 , wherein the lenses are arranged such that each lens overlaps an adjacent lens.
