Led Luminaries

XLamp XHP70.3 leds are the third generation of Cree’s ‘extreme high power led series’, with improved optical performance versus the previous generations, with higher intensity through optics than the second generation and with the XHP family’s highest on-axis intensity. They are optimised for outdoor and lighting applications that require large amounts of light output from small luminaires, such as in ...

The first companies have earned ‘Zhaga-NFC’ inter-operability certification for NFC readers intended to be used with suitably-enabled smart LED luminaires. NFC (‘near-field communication’) is one of several techniques being used to read data from, and changing of settings of, LED drivers in the field. Zhaga specifications are divided into ‘Books’. Book 24 and 25 define the programming of NFC-enabled luminaire ...

Three minutes of 670nm exposure in the morning appears to make the eyesight of humans over 40 years old better for a week, according to Imperial College London. The improvement is shown in cone-mediated colour contrast thresholds, tested in people from 37 to 70 years old in this research. Improvements have been seen before, using light at ~40mW/cm2, but this work ...

The Thomas Pocklington Trust has once again updated it guide for lighting spaces in which partially-sighted people live, and has broadened its appeal to beyond its original intended audience. “Lighting makes such a difference for partially sighted people, often enabling them to maintain their independence,” the Trust told Electronics Weekly. Now at issue 3, ‘Lighting in and around the home: A ...

Osram has introduced horticultural lighting leds with a ‘batwing’ output distribution. Implemented in Oslon Square Batwing, the distribution comes purely from a primary lens built into the pacakge. “Current LED fixtures often have a lambertian primary lens and no secondary optic, or a simple glass cover, which lead to hotspots with high concentration of light directly under the luminaire,” according ...

Signify has introduced “the first Philips LED A-class bulbs that meet the more stringent EU Ecodesign and Energy labeling regulations that come into effect on September 1, 2021”, according to Signify. “The new Philips LED bulbs with a longer lifespan.” They will be available in 40W (below) and 60W (above) equivalents and should be producing at lease 210lm/W. “Thanks to this technological ...

LED streetlights harm insect populations more than sodium streetlights, is the finding of the UK Centre for Ecology & Hydrology (UKCEH), which worked with Newcastle University and Butterfly Conservation. “The total abundance of moths in Britain has decreased by one third over the past 50 years. Understanding, and reversing, the causes of this worrying decline is a top priority for us,” ...

Nichia has created an led with the feel of HPS (high-pressure sodium) lighting, it claims. Nichia: HPS lighting can create a nostalgic or elegant atmosphere “Global efforts to phase-out the use of HPS continue to be met with a resistance to using white LED replacements. Due to this lack of a viable and sustainable alternative, HPS have remained exempt from ...

Ledvance is advising lighting wholesalers about compliance with the Single Lighting Regulation (SLR) and Energy Labelling Regulation (ELR). It also points out that the European Product Registry for Energy Labelling (EPREL) now centralises relevant information for all light sources on the market, for the first time. The new regulations redefine products into ‘light sources’ and ‘containing products’. SLR and ELR regulations ...

Osram has developed its own emissive quantum dot technology, and is using it in a range of 90CRI lighting LEDs. “‘Osconiq E 2835 CRI90 (QD)’ pushes efficiency values to new heights, even at high colour rendering indices and warm light colours,” according to the company. “The LED meets the requirements of the Single Lighting Regulation [mandatory in Europe in September ...
