Abstract
In a group of associated luminaires, a master luminaire may receive control signals from an external controller, such as over a set (pair) of wires (input leads), and will pass these signals wirelessly (via signaling LEDs and phototransistors) to slave luminaires. Hence, the slave luminaires need not have input leads or control wires extending therefrom. Eliminating wires extending from luminaires may increase the reliability and longevity of the luminaires. Various modulation schemes may be applied to address individual slave luminaires or groups thereof. Method and Apparatus are disclosed.
Claims20
A method of controlling the operation of one or more luminaires comprising LED lighting arrays and driver/control circuitry, the method comprising:
- providing a control signal to one of the luminaires, said luminaire operating as a master luminaire and comprising an optical signal transmitter for transmitting optical control signals to other luminaires;
- and
- providing at least some of the other luminaires with optical signal receivers for receiving the optical control signals;
- wherein the optical control signals control an operating parameter of the LED lighting array.
A luminaire comprising:
- an LED lighting array disposed on a printed circuit board (PCB);
- driver and control circuitry;
- and
- at least one of an optical signal transmitter and optical signal receiver.
