LED headlamps with supplementary traffic safety functions

On an operational front, GE’s LED Iberia solution is estimated to generate savings amounting to nearly US$10,000 per annum in terms of energy usage and maintenance. From an environmental perspective, the energy savings is equivalent to eliminating approximately 53,850kg of carbon dioxide car emissions per year or saving 89.33 acres of trees.These garage and canopy luminaires with integrated lighting control technology provide over 60-percent reduction in operating costs compared to the traditional Agent of floodlight metal halide fixtures. The PixelView Control occupancy sensing system offers fully integrated individual luminaire management with unparalleled coverage.When wildlife is sensitive to lighting and local ordinances require safe night lighting, the Coastal Light is the preferred solution. The Coastal Light is wildlife-friendly with its amber LED source. The amber option is now available on Lighting Science's most popular luminaires—the Prolific LSR and the Road master RMS roadway lighting. The Coastal Lamp is also available for retrofitting a variety of existing fixtures.
The Forefront Series represents a breakthrough in both performance and design. Engineered to maximize the capabilities of the LED source, these luminaires are available in various sizes and performance optical distributions that enable dramatic energy and maintenance savings over traditional HID technologies. Osram is to develop glare-free adaptive headlights, where modulating multiple LED die within a headlight allows the shape of its beam to be varied in response to data from forward-facing cameras in the vehicle.Low-beams that adapt with vehicle speed are another aspect: at high speed the range of the light is automatically increased, while in city traffic the beam is widened to include more of the pavement and road edges.

"The aim of this project is to develop the technical framework for a new class of energy-efficient LED headlamps with supplementary traffic safety functions," said Osram. "This can provide the basis for adaptive forward lighting systems [AFSs] that offer drivers and passengers increased safety.We have brought together major-league players in their respective sectors, assembling a wealth of expertise for this pioneering project around one table," said project coordinator Stefan Grötsch, also responsible for LED applications in automotive lighting at Osram.One of the biggest single factors contributing to the cost of an LED wafer is the volume of chemicals used in the MOCVD process. The novel chamber and gas injector design in the Wholesale Led high bay light result in highly efficient use of gas and pre-cursor chemicals when compared to MOCVD systems currently in the market. The GaN-500 has been field tested in a customer fab for more than one year. Over the course of hundreds of runs, materials performance, gas consumption, and machine reliability have been extensively monitored and validated. We are extremely excited to report that this testing has confirmed that our product can produce wafer uniformities and growth rates that are comparable with established systems, while at the same time consuming up to 40% less gases and chemicals.
