US 2015/0084525 A1 · ADJUSTABLE CONTROL FOR BI-LEVEL LUMINAIRE DRIVER

Abstract

An adjustable bi-level lighting control is for use in connection with LED luminaires having an LED, a current control circuit, a driver circuit and an AC source. The LED luminaire is directed to illuminate an area having intermittent occupancy. The adjustable bi-level lighting control comprises a dimmer supplying a first control signal to the current control circuit, to control current flow to the LED. An occupancy sensor, responsive to an occupant entering the area, supplies a second electrical control signal to the dimmer. An adjustable control connected to the dimmer allows for selective adjustment of the first electrical control signal. Low and high level potentiometers selectively adjust the first electrical control signal to low and high levels, thereby selectively adjusting the LED to low and high levels of intensity, respectively.
