by Shane Henson — April 3, 2013—Acuity Brands Inc. recently announced that the company’s Lithonia Lighting D-Series Area LED luminaires are even more powerful and useful with the integration of Sensor Switch motion sensors.
According to the provider of intelligent lighting solutions, its D-Series Area Size 1 and Size 2 light-emitting diode (LED) luminaires utilize motion sensors to increase energy savings in outdoor applications such as parking lots, plazas, campuses and streetscapes, saving approximately 80 percent in energy than comparable fixed output metal halide fixtures.
Created for 15-to 30-foot mounting heights, the luminaire-mounted motion sensor provides a 15-to 20-foot coverage radius and a 300-degree coverage pattern. Innovative presets gradually dim the LED luminaire to a pre-set level when the area becomes unoccupied, achieving energy savings while still providing security lighting. When motion is detected, the luminaires quickly ramp to the full output. The motion sensors feature nine fully programmable attributes, including maximum output, motion time delay, dimmed level, fade down and ramp up times.
“With motion sensing, we are able to further enhance the benefits of LED technology to deliver even more energy savings and increase the lifespan of the luminaire,” said Eric Gibson, value stream manager for Lithonia Lighting, Outdoor. “By integrating the motion sensor and the luminaire, we eliminate the need to specify and install the lighting and controls separately. The sensor comes pre-configured to standards established by the customer.”
