1. A lighting system comprisinga plurality of suspended ceiling rails;
- a ceiling panel configured to be supported by said rails, said panel defining a first surface having cone-shaped recesses and a first edge;
a plurality of light elements, each light element including at least one light-emitting diode (LED), and being at least partially embedded in said recesses, each recess being configured to receive a corresponding light element and one or more of said recesses including a reflector configured to reflect light emitted by the light element therein primarily away from said first surface, and an electrical power delivery system coupled to said light elements, said delivery system including a conductive strip extending along said panel and being terminated by a connector disposed at said first edge, said strip including one or more wires connecting said LEDs in series, and said rails including at least one receptacle configured for mating engagement with said connector for transmitting electrical power from said rails to said strip.

Abstract
An overhead lighting system is formed by embedding a plurality of light elements within a support structure, such as a ceiling panel of a suspended ceiling. The light elements are preferably ultra-bright light emitting diodes (LEDs). The LEDs are mounted in the ceiling panel so that the light emitted from each LED projects from a first surface of the ceiling panel and down into a respective space.

4. A lighting system comprising
a suspended ceiling panel having opposite first and second surfaces and a peripheral edge; -
a plurality of light elements at least partially recessed into said first surface so that when lit, the light elements direct light primarily away from said first surface;
a conductive strip on said second surface, said strip including at least one conductive path electrically connecting said light elements with a panel connector disposed at said edge so that when power is applied to the panel connector, the light elements are lit, and electrical power delivery means for supplying power to said light elements, said delivery means including a plurality of suspended ceiling rails supporting said panel at said edge, a rail connector on one of said rails said rail connector being positioned on said one rail so as to engage and electrically contact the panel connector of said panel, and power conducting means for conducting power to said rail connector. - View Dependent Claims (5, 6, 7)
said conductive strip includes a plurality of different conductive paths separately connecting different groups of said light elements with said panel connector, and control means for separately controlling the power delivered to each group of light elements. -
6. The lighting system defined in claim 4 wherein the power conducting means include one or more conductors extending from said rail connector along one or more of said rails, said conductors being adapted for connection to a power source.
-
7. The lighting system defined in claim 4 wherein each light element includes at least one LED.

8. A lighting system comprising
a conductive strip supporting a plurality of LEDs, a panel connector and one or more conductive paths interconnecting said LEDs with said panel connector, and a panel having opposite first and second surfaces, a corresponding plurality of through holes extending between said surfaces and a peripheral edge, said holes being positioned on the panel so that when said strip is placed flush against the second surface of the panel, the LEDs project through said holes toward said first surface and the panel connector is disposed at said edge.

14. A method of illuminating a room having a suspended ceiling composed of rails and panels, said method comprising the steps of
forming a plurality of perforate panels each with opposite surfaces, a periphery and an arrangement of through holes extending between said surfaces; -
forming conductive strips each of which supports and interconnects a corresponding arrangement of LEDs with a panel connector;
securing said strips to the second surfaces of the perforate panels so that the LEDs project through the holes therein toward the first surfaces thereof with the connectors being disposed at the peripheries thereof;
placing the perforate panels on the rails of the suspended ceiling instead of the panels so that the panel connectors are disposed adjacent to the rails;
securing rail connectors to the rails of the suspended ceiling at locations thereon opposite the panel connections so that the opposing pairs of panel and rail connectors interconnect, and providing power to said rail connectors via conductors extending along selected ones of the rails.
