Abstract
A solid state lighting (SSL) with a solid state emitter (SSE) having thermally conductive projections extending into an air channel, and methods of making and using such SSLs. The thermally conductive projections can be fins, posts, or other structures configured to transfer heat into a fluid medium, such as air. The projections can be electrical contacts between the SSE and a power source. The air channel can be oriented generally vertically such that air in the channel warmed by the SSE flows upward through the channel.
Claims16
A solid state lighting (SSL) device, comprising:
- a reflective surface angled relative to a primary direction of the SSL device by a non-zero first angle Φ, wherein the reflective surface has a forward portion located further in the primary direction than a remainder of the reflective surface;
- and
- a solid state emitter (SSE) angled relative to the primary direction by a non-zero second angle θ,
- wherein the first angle Φ and the second angle θ are configured so that light emitted from the SSE is reflected by the reflective surface in the primary direction of the SSL device, and
- wherein light emitted from a first peripheral region of the SSE is directed towards the forward portion of the reflector.

A solid state lighting (SSL) device, comprising:
- a reflector having a first reflective surface and a second reflective surface, each of the first and second reflective surfaces angled relative to a primary direction of the SSL device by a non-zero first angle Φ, each of the first and second reflective surfaces having a forward portion further in the primary direction than a remainder of the corresponding reflective surface;
- and
- first and second solid state emitters (SSEs), each angled relative to the primary direction by a non-zero second angle θ, wherein the first angle Φ and the second angle θ are configured so that light emitted from the first and second SSEs is reflected by the first and second reflective surfaces, respectively, in the primary direction of the SSL device,
- wherein light emitted from a first peripheral region of the first SSE is directed towards the forward portion of the corresponding first reflective surface, and
- wherein light emitted from a first peripheral region of the second SSE is directed towards the forward portion of the corresponding second reflective surface.
