Adaptive exterior lighting products are entering the marketplace at a rapid rate. By coupling features such as occupancy-based lighting controls with efficacious, dimmable sources, these solutions offer 30 – 75% energy savings over traditional systems.
Philips Lighting has released a ceramic metal halide, direct-retrofit lamp that can be used with both probe- and pulse-start ballasts. The Philips Energy Advantage CDM lamp with AllStart Technology saves energy, improves efficacy and color rendering, maintains light levels, and is more affordable than traditional metal halide (MH) lamps. Philips says the lamps “provide true universal operation regardless of orientation without compromising light quality, and make installation and maintenance easier than ever.”
Philips Day-Brite and CLTC partnered on this SPEED-sponsored project to demonstrate a adaptive high intensity discharge (HID) wall pack from Philips Day-Brite’s established NiteBrites product line. The product provides dynamic light levels to surrounding areas based on occupancy using a single HID lamp and fixture-integrated occupancy sensor.
Many of the emerging light sources used for exterior lighting, namely light-emitting diode (LED) and advanced ceramic metal halide (CMH) lamps, provide full-range dimming. Occupancy sensors have provided adaptive lighting controls in exterior parking and area lighting applications, but some applications are not compatible with sensor coverage patterns. In these scenarios, combining dimmable sources with a controller that dims based on time of day can achieve comparable energy savings to utilizing occupancy sensors.
The California Energy Commission sponsors the development and demonstration of energy-efficient, environmentally safe building technologies. It does this, in part, through the State Partnership for Energy Efficient Demonstrations (SPEED), a program that demonstrates innovative lighting and HVAC technologies. The SPEED program is managed by the California Institute for Energy and Environment (CIEE), which is a branch of the University of California. The California Lighting Technology Center (CLTC) is subcontracted by CIEE to develop and implement lighting technology demonstrations.
