Verbatim used LuxLive in London to launch anti-glare AR111 retrofit LED bulbs and demonstrate a new range of linear LED products. Low glare is the big marketing point. “To avoid the uncomfortable glare, the lamps mimic the lighting effect of a traditional halogen lamp by emitting light indirectly via the reflector,” said the firm, which is claiming CRI >90 for the ...
Cree has created a 3,000K version of its IG Series of luminaires for vehicle parking, and has added 0-10V dimming as a standard feature. The light use waveguides to spread where it is wanted, which Cree brands WaveMax. for low glare, little light is emitted outside +/-50 downwards – see the data sheet. “Parking structure operators are under constant pressure ...
Shining 670nm red light on bees could ameliorate damage caused by neonicotinoid insecticides, according University College London and the strangely named university City, University of London. “The researchers found that when shining a specific wavelength of red light (670nm) it significantly reduced bee death rates and improved cell energy levels, mobility and visual function in animals exposed to neonicotinoid pesticides such ...
New research by scientists from the University of Bristol has revealed that domestic LED lights are much less attractive to nuisance insects such as biting midges than traditional filament lamps. The study, funded by the Natural Environment Research Council and UK lighting manufacturer Integral LED, used customised illuminated insect traps at 18 field test sites across south-west England, lit by ...
Plessey will exhibit the first standard LED module based on its Stellar beam forming technology at electronica . According to prelimiary data, the Orion PLWS3000 module is only 5.6mm thick but achieves a beam angle of +/-12.5°. The module is 82mm in diameter and has a hermal resistance of 1°C/W. “The greatly reduced form factor eliminates design constraints providing lighting designers with ...
Harvard Technology, which manufactures in the UK, will be exhibiting its latest range of products at LUX Live on stand K2. It will unveil programmable LED drivers, the latest addition to its CoolLED range, and be showing the recently launched Gen III Elite, Pro and Classic light engines. Also on display will be the newly updated EyeNut Combined Emergency Driver. A ...
St. Peter’s Square in Rome is now consuming ~70% less energy following a conversion to LED lighitng, by Osram. The project was conceived concept by the Direzione dei Servizi Tecnici del Governatorato dello Stato della Città del Vaticano, the same organisation that with Osram converted the Sistine Chapel to leds whose spectrum was deigned to get the correct apparent colour ...
Osram Opto Semi will show products at Electronica in Munich including a new surface mountable Oslon Black Flat S multi-chip led for pixelated headlights, and a laser diode specifically for lidar. Also, “results from current research projects will provide insights into the future of light,” said the firm. See it at booth 107 hall A3 at the Munich Exhibition Center ...
Built in the middle ages, the St. Jean granary in Angers France has had a led lighting make-over, and now offers different lighting scenarios depending on how it is being used. “The new lighting for this prestigious community hall blends discreetly in the original architecture with its beams, slate walls and round arches,” said Tridonic, which provided leds and controls. ...
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 ...
