Abstract
An illuminating device can comprise two substrates each having two surfaces, one of each can be configured to mount solid-state lighting devices wherein the two substrates are separated by a defined gap. The two substrates are electrically and mechanically connected and can support or be supported with an enclosure such as an optic. This configuration provides thermal decoupling and uniform illumination when assembled as per the embodiments explained.
Claims20
A solid-state lighting apparatus comprising:
- a first substrate having an upper surface and a lower surface that is opposite the upper surface, the upper surface configured to mount a plurality of first solid state light emitting devices thereon to provide first emitted light from the solid-state lighting apparatus;
- a second substrate, uniformly spaced apart from the first substrate by a predetermined gap, the second substrate having an upper surface and a lower surface that is opposite the upper surface, the lower surface of the second substrate facing away from the first substrate and configured to mount a plurality of second solid-state light emitting devices thereon to provide second emitted light from the solid-state lighting apparatus, wherein a combination of the first and second emitted light provides all light emitted by the solid-state lighting apparatus;
- and
- said first and second substrates being exposed to ambient air only by the predetermined gap to cool said first and second substrates.

An illuminating device comprising:
- a first substrate with one or more first light emitters mounted thereupon;
- a second substrate with one or more second light emitters mounted thereupon;
- said first and said second substrates uniformly spaced apart by a predetermined gap across a width of said first and said second substrates, wherein, only said gap exposes said substrates to ambient air;
- a first optical chamber enclosed by said first substrate and a first optic;
- and
- a second optical chamber enclosed by said second substrate and a second optic,
- wherein a combination of the light emitted from said first and second light emitters provides all light emitted by the illuminating device.
