ADJUSTABLE CONTROL FOR BI-LEVEL LUMINAIRE DRIVER

摘要

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.

1. An adjustable bi-level lighting control for use in connection with an LED luminaire directed to illuminate an area, the luminaire having an LED, a current control circuit supplying power to the LED, a driver circuit supplying power to the current control circuit, and an AC source supplying power to the driver circuit, the adjustable bi-level lighting control comprising:
a dimmer operatively connected to the current control circuit, the dimmer being adapted to supply a first electrical control signal to the current control circuit so as to control current flow to the LED; an occupancy sensor operatively connected to the dimmer, the occupancy sensor being adapted to supply a second electrical control signal to the dimmer, the occupancy sensor being responsive to an occupant entering the area; and an adjustable control operatively connected to the dimmer, the adjustable control being adapted to selectively adjust the first electrical control signal.
