Abstract
An electronic ballast system controls one or more ballasts of HID or fluorescent lamps, which are controlled in an “on/off” manner by a ultra low power controller that is isolated for a primary power circuit or derives its very low switch power from the ballast itself. The on/off control provides a near lossless control system. This system may be applied to electronic ballast for operates at fractional power levels corresponding to different lighting intensities and with conventional occupancy sensors. The system may also be applied to other electronically compatible end-use devices and applications.
Claims6
A remote switch for low-power on/off control of non-ballasted lighting, namely light emitting diodes and halogen lamps, comprising:
- a remote switch connected to at least one non-ballasted lighting unit;
- at least one power supply providing DC power;
- a controller interfacing with said remote switch communicating with said at least one non-ballasted lighting unit;
- said controller including a DC-DC converter to reduce the voltage from a predetermined voltage supplied by said at least one power supply to a second predetermined voltage required by said at least one nonballasted lighting unit.
