LED Luminaires Power Supply
First Claim
1. A power supply comprising:
- a first connector to receive line power;
a plurality of supply and control circuits to individually convert the line power to power necessary to drive associated LED luminaires; and
a plurality of second connectors to provide the necessary power to the associated LED luminaires.

Abstract
An LED luminaires power supply that isolates dangerous line power from the LED luminaires. The power supply'"'"'s footprint may enable retrofitting in existing lighting fixtures (e.g., replace ballast in florescent tube troffer). The power supply may individually power a plurality of LED luminaires based on power requirements of the individual LED luminaires. The power supply may receive and interpret TRIAC dimmer signals and/or other lighting protocol commands and provide dimming and/or other lighting scenarios to the LED luminaires. The power supply may include identification readers to read identification and/or power requirements for the LED luminaires being powered thereby (stored in luminaires or in adapters connected to luminaires). The LED luminaires driven by the power supply may include individual lighting fixtures (e.g., LED tubes, LED bulbs), a plurality of LED light arrays in a single light fixture (e.g., LED street lights, LED high hats), or some combination thereof.

14. A power supply comprising:
-
a first connector to receive line power; a supply and control circuit to convert the line power to a power profile for an LED luminaire to be powered by the power supply; a second connector to provide the power profile to the LED luminaire; and an identification reader to read the power profile for the LED luminaire from the LED luminaire and provide the power profile to the supply and control circuit. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A power supply comprising:
-
a first connector to receive line power via a TRIAC dimmer; circuitry to imitate to the TRIAC dimmer that it is connected to a resistive load; a plurality of supply and control circuits to individually provide power to LED luminaires connected thereto that are operational, wherein each supply and control circuit is to convert the line power to a power profile for an associated LED luminaire, wherein each supply and control circuit includes a driver to convert the line power into small slices where frequency of the small slices is based on the power profile for the associated LED luminaire and the frequency determines current that will flow through the associated LED luminaire, wherein each driver receives feedback related to the current flowing through the associated LED luminaire and makes necessary adjustments, and wherein at least one driver receives dimming signals from the TRIAC dimmer, interprets the TRIAC dimming signals and makes necessary adjustments to provide dimming; a plurality of second connectors to provide the power profile to the associated LED luminaires; and a plurality of identification readers to read the power profile for the associated LED luminaires from the associated LED luminaires and provide the power profile to the associated driver. - View Dependent Claims (25, 26, 27)
