Led Luminaries

Lumileds is aiming at horticuture with its SunPlus series, which is binned in photosynthetic photon flux (PPF) – the plant equivalent to Lumens, measured in µmol/s. SunPlus 20 are 2 x 2mm devices aimed at greenhouses farmers wanting to supplement high bay lighting with specific wavelengths – available in in 440-460nm royal blue, 655-675nm deep red, 720-750nm far red, and then two broad ...

Released under Cree’s Essentia brand, the LED Surface Wrap operates at 115 lm/W and comes in two lengths: ~600mm and ~1.2m. It comes with 0-10V dimming to 5%, and has options of emergency back-up and a field-installed occupancy. The aim is to replace traditional fluorescent fixtures in commercial hallways, utility rooms and low ceiling areas. “It sets a new industry standard for ...

A company called Soltech Solutions, from Pennsylvania, is aiming at a niche that I haven’t heard anyone else going for – aesthetically-pleasing grow lamps for offices and homes. Normally, the light from grow lamps looks pretty purple as they emit plenty of red and some blue, but little green. Aspect, as it has been branded, is different. “It uses a ...

Cree is claiming to be making “industry’s brightest side-view leds”, intending them for gaming machines. QLS6A and QLS6B are RGB and deliver “up to 66% higher luminous intensity than other side-view LEDs”, saod Cree. “The side-view packaged LEDs enable clearer image displays for a better gaming experience and higher visual impact in pachinko, slot and other video gaming machines.”   Typical luminous ...

The lighting for the G20 Summit in Hangzhou, China includes leds from Osram. The firm has supplied around 400 of its own Kreios PAR units (pictured), and there are Osram LEDs in luminaires supplied by the Chinese company Roleds for wallwashing, walkway lights and accent lighting. Included amongst the leds are Duris S 5 Color – which come in colours including ...

Spotted on a Fairchild A10 Warthog ground-attack aircraft at an airshow in Wisconsin, and photographed by commentator of this parish Steve K, this landing light is a long way from Ullverston Cumbria, where it was made by Oxley. Designed to replace a PAR46 bulb, it has a 200,000cd 6,000K white mode (+/-11° to 10%), and a 100W/sr 850nm infra-red covert mode ...

Cree’s MHB-B is an led intended to meet DesignLights Consortium 4.0 Premium requirements. The ceramic devices deliver up to 931 lm at 85°C – at 13% higher lm/W than the MHB-A LED, said Cree, from the same 5 x 5mm package. The firm is pitching it against mid-power leds. It has a MHB-B DLC 4.0 Premium high-bay reference that makes 24,000 lm ...

Lumileds is aiming at restaurant and creating ambience, as it adds ‘AtmoSphere Technology’ to its Luxeon Stylist Series of lighting leds. “Halogen lighting had long dominated restaurant, bar and other hospitality lighting due to its ultra warm light capability – even while leds offered a 70-80% energy savings versus halogen,” said the firm. “Standard leds do not offer the optimal ...

Thanks to Erik Milz of Cree for bringing this to my attention. The US Municipal Solid-state Street Lighting Consortium has produced a short but detailed review of the American Medical Association’s comments on LED street lighting. By MSSLC director Bruce Kinzey, of the US government’s Pacific Northwest National Laboratory, the review is backed-up with links to science. The AMA report is good, ...

While broadly supporting led street lighting, the American Medical Association recently raised concerns about the technology, and the US Lighting Research Center then criticised some of the AMA’s conclusions (link). As a reality check, Electronics Weekly spoke to Erik Milz, v-p for marketing outdoor lighting at streetlight maker Cree. Don’t get the wrong idea here, the AMA report is thoughtful ...
