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.
In the summer of 2010 the California Lighting Technology Center (CLTC) and Philips Hadco produced an adaptive solution that combined a dimmable LED source and a mounting collar equipped with occupancy sensors. The collar provides 360-degree occupancy sensor coverage. This demonstration involved whole-head replacement of the existing luminaires, but results could also be achieved with a retrofit kit. The new luminaires feature good color quality, improved efficiency and a longer lifespan.
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.
The PIER Program sponsored development of the adaptive LED bollard, an innovative technology designed to combat the energy wasted on overlighting unoccupied urban spaces. To successfully reduce energy consumption and provide dynamic light levels to the surrounding environment, project partners selected long-life light emitting diodes (LED) and fixture-integrated occupancy sensors to create a unique adaptive bollard. This combination delivers long life, low-energy consumption, and dynamic light output based on occupancy.
Lighting California's Future – Lighting controls systems are readily available in the market that turn lights off when spaces are unoccupied or when sufficient daylight is available. However, installing these systems involves new wiring or rewiring and can be an expensive proposition to retrofit existing buildings. Adura Technologies, in partnership with the California Lighting Technology Center, developed a wireless integrated photosensor and motion sensor system that communicates wirelessly through radio frequency to circumvent this issue.
The UC Davis Smart Lighting Initiative was established in 2010 to improve the quality and efficiency of both indoor and outdoor lighting on campus. The initiative's primary goal is to reduce UC Davis's electricity use for lighting by 60 percent, based on 2007 levels of energy use. The effort was inspired by the California Public Utilities Commission (CPUC) and its call to reduce statewide electricity consumption for lighting by 60 percent or more by 2020.
The New York Times – Parking garages are the third most frequent place for crime in the U.S. Security professionals agree that parking garage design influences the level of crime significantly. The easiest way to deter criminal activity in preexisting structures is by installing bright, white lights, coupled with occupancy sensor controls.
LD+A – The University of California, Davis, unveiled one of the most advanced outdoor lighting systems in the country this past June. Dubbed the Adaptive Campus Control System, it integrates over 1,600 individually addressed, dimmable LED luminaires with various applications – streetlights, wall packs, area lights, and post tops – into an advanced, wireless lighting controls network.
High Performing Buildings – The drive for building efficiency is creating innovative technologies that are finding their way into marketplace. This new feature in HPB magazine showcases the applications and capabilities of technologies in real projects, and also recognizes the providers of some of the innovative products.
