Abstract
A light-emitting diode (LED) luminaire control system comprising a control circuit is adopted to provide remote control signals to operate an external luminaire that comprises LED arrays and a power supply. The LED luminaire control system further comprises a relay switch, a remote controller, and a transceiver circuit. When the remote control signals are initiated by the remote controller with phase-shift keying (PSK) signals transmitted, the transceiver circuit can demodulate such PSK signals and subsequently send decoded commands to the LED luminaire control system to control the luminaire by turning on and off and dimming up and down the external luminaire.
Claims19
A light-emitting diode (LED) luminaire control system, comprising:
- a power supply converter circuit configured to be coupled to alternate-current (AC) mains to convert a line voltage from the AC mains into a first direct-current (DC) voltage;
- a first voltage converter circuit configured to convert the first DC voltage into a second DC voltage less than the first DC voltage;
- a control circuit comprising a relay switch, wherein the relay switch comprises a power sensing coil with a set voltage and a reset voltage and is configured to couple the line voltage from the AC mains to an external power supply unit to operate thereof when enabled, subsequently powering up external one or more LED arrays coupled with the external power supply unit;
- and
- a transceiver circuit comprising a receiver and a decoder and controller, the transceiver circuit coupled to the control circuit and configured to receive and demodulate various phase-shift keying (PSK) band-pass signals and to output either a first pulse signal or a second pulse signal,
- wherein:
- the relay switch further comprises a first input electrical terminal and a pair of input electrical terminals;
- the first input electrical terminal is configured to couple to a hot wire of the line voltage from the AC mains;
- and
- the pair of input electrical terminals are coupled to the power sensing coil and configured to receive either the set voltage or the reset voltage and to respectively set up an on-state or an off-state of the relay switch.
