Lumileds’ LUXEON Rebels power LED security floodlights

Philips Lumileds of San Jose, CA, USA says that its LUXEON Rebel LEDs are being used by intelligent lighting and sensor fixture manufacturer Steinel of Herzebrock-Clarholz, Germany to power its new XLed range of security floodlights, which use one-third of the energy consumed by conventional floodlights, it is claimed. The XLed is available as the XLed 25 (with 25 LUXEON Rebels for very high luminous flux and total power consumption of about 60W) and the more compact XLed 10 (with 10 LUXEON Rebels and total power consumption of about 25W).

To extend the energy-saving benefits of the LUXEON-based XLed fixtures, Steinel has incorporated a wide-angle motion sensor for use in security applications. An electronic control unit switches the floodlight on instantly at full power when a human body is detected, but turns it off after a period of time or reduces light output to 10% of maximum, as decided by the user.

“The LUXEON Rebel LEDs are very temperature-resistant,” says Steinel’s managing director Thomas Möller. “In product development we tested many different LEDs, and we found that the Philips Lumileds LEDs were the best for our application,” he adds.

Lumileds says that its LUXEON Rebel white LEDs suit Steinel’s XLed, where the requirement is for a bright and compact light source that delivers high efficacy and offers a long operating lifetime, remaining robust even in the most demanding operating conditions. XLed is designed to operate at full power for sustained periods and carries a warranty for an operating lifetime of 50,000 hours (45 years at three hours’ use per day).

LUXEON K2 LEDs used by D-LED for museum lighting

Philips Lumileds also says that its LUXEON LEDs are being used by D-LED Illumination Technologies Ltd of Hod-Hasharon, Israel (a member of the LUXEON Lighting Network) in its D-Spot and Nano long-life LED luminaires embedded into walls, floors and hard-to-reach recessed spaces (where conventional light sources would be impractical) at the new Yitzhak Rabin Museum in Tel Aviv. The aim is to create small, almost invisible light sources that do not detract from the artifacts, as well as minimizing disruption to visitors from unplanned maintenance.

Each luminaire uses LUXEON K2 LEDs driven at 700mA to achieve the required light output and lumen maintenance. The project was enabled by D-LED’s experience with solid-state lighting solutions, coupled with engineering expertise and support from Future Lighting Solutions (Israel).

“By using power LEDs, we were able to make backlighting luminaires that could be accommodated in very small spaces behind displays, and equally to design discreet spotlights - each using three white LUXEON LEDs - that are so small that the eye is not drawn to or distracted by them,” says lighting designer Noa Lev, who implemented the interior lighting of the museum.
