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.
Claims18
A method of providing illumination, comprising:
- (a) providing a first substrate mounted with a first set of solid-state light emitters,
- (b) providing a second substrate mounted with a second set of solid-state light emitters,
- (c) spacing said substrates apart by a predetermined gap,
- (d) exposing said substrates to ambient air only via said gap completely along the perimeter of said substrates,
- (e) providing electrical power to drive said light emitters,
- (f) orienting said substrates such that the light emanating from said first light emitters is in substantially opposite direction to the light emanating from said second light emitters, and
- (g) diffusing the light emitted by said first and second sets of light emitters, whereby, said substrates are cooled by ambient cross air circulation in the said gap.

An assembly method of a solid-state lighting apparatus comprising:
- (a) securing a driver PCB inside a first optical chamber that is partially bounded by a first light-transmitting optic,
- (b) securing a first substrate, mounted with a first set of light emitters, on to said first optic,
- (c) securing a support structure to said first substrate,
- (d) securing a second substrate, mounted with a second set of light emitters, on to said support structure such that the first and second substrates are spaced apart by a gap exposed to the ambient air
- (e) securing a second light-transmitting optic to said second substrate,
- (f) securing an electrical supply connector to said first optic, and
- (g) providing means of electrical connections between said connector, said driver PCB and said substrates.

A solid-state lighting unitary assembly comprising:
- a first substrate having an upper surface and a lower surface that is opposite the upper surface, the upper surface configured to mount at least a first solid-state light emitting device thereon;
- a second substrate having an upper surface, and a lower surface that is opposite the upper surface and configured to mount at least a second solid-state light emitting device thereon;
- said substrates spaced apart by a predetermined uniform gap exposed to the ambient air;
- said gap configured to be completely open to the ambient air along the perimeter defined by said substrates;
- and
- mechanical supports that provide electrical connections between said substrates;
- whereby,
- said second substrate supports said first substrate in conjunction with said supports, and the combination of light produced by electrically powering said light-emitting devices makes up all light produced by said assembly.
