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.
Claims28
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;
- and
- a plurality of lenses, wherein each lens has a curved surface and is aligned with a single corresponding SSL emitter.
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
- a converter material over the SSL emitters, wherein the converter material emits light at a second frequency different than the first frequency.
A method of manufacturing a solid state lighting (SSL) device, comprising:
- attaching a plurality of SSL emitters to a support such that the SSL emitters are connected to a common anode and common cathode;
- and
- positioning a plurality of lenses relative to the SSL emitters such that each SSL emitter is aligned with a single one of the lenses, and wherein each lens has a curved surface.
