Abstract
Ceiling illumination is a method by which indirect lighting can be achieved in a space to replace a recessed downlight and to provide better light utilization and application efficiency. A solid-state lighting apparatus is invented which includes a support structure and a substrate for mounting LEDs and configured to emit light in a direction such that, when installed as per the invented method, can illuminate a ceiling and subsequently the space below it.
Claims20
A solid-state indirect lighting apparatus comprising:
- means for electrical power transfer;
- a substrate with at least an aperture and configured to mount a plurality of solid-state light emitters on one side thereof;
- and
- a tubular opaque support structure configured to support said substrate;
- whereby, a portion of the light emitted by said solid-state light emitters directly passes through said aperture upon reflection from surfaces in proximity of said apparatus.
A system of electrically powered indirect illumination comprising:
- a space with a ceiling having a ceiling portion;
- and
- a solid-state lighting apparatus further comprising:
- an opaque tubular structure configured to house driver circuitry and support a substrate;
- and
- an aperture configured to pass direct reflected light from said ceiling portion through;
- said apparatus situated in a predetermined close proximity of said ceiling portion and further configured to cast majority of its light on to said ceiling portion;
- whereby, said space is illuminated by the reflection of said light from said ceiling.
A method to illuminate a space comprising the steps of:
- (a) installing a solid-state indirect lighting apparatus, in its entirety, below and within ten inches of a ceiling of said space;
- (b) providing electrical power to said apparatus;
- (c) ensuring that a majority of light emitted by said apparatus is incident on said ceiling;
- (d) ensuring that a majority of said incident light is reflected towards said space;
- and
- (e) ensuring that a portion of said reflected light passes through said apparatus;
- whereby, said space is uniformly illuminated while reducing glare and increasing application efficiency.
