LED Lighting

Crocus, the magnetically enhanced IC specialist, has prototyped a bendable display using flexible sensors and is looking for applications and customers for it.

In a long-needed move, LED standards body Zhaga has picked up the baton and started work on a specification for chip-on-board (CoB) LED arrays. A Zhaga Book will specify a family of six rectangular or square LED modules with different dimensions. The rest of the content is still being discussed (see below). CoBs are becoming the standard LED light source ...

Michael Jaeger, patent attorney at leading UK patent and trade mark attorneys Withers & Rogers LLP, writes: GB Patent Number: GB2497767 Granted to:  TWM Traffic Control Systems Ltd   This month’s patent caught my eye for a number of reasons. First, it is a nice follow-on to my article last month, since the invention is surprisingly simple and superficially straightforward (but as ...

Sharp has combined three LED lighting components – a chip-on-board (CoB) emitter, holder and thermal interface – in one solderless assembly. The result is a more straight-forward way to build a high brightness LED assembly by attaching the module to its heat sink by two screws and push-fit electrical connections. According to Silica, which is selling the Intermo module, device’s ...

In this article, I would like to talk a little bit about LEDs, including why they will become the lighting source of choice, how to power them and also, how to protect them from the hazards they face within their respective implementations. These include high bay lighting, architectural lighting, outdoor street lighting and even 75W incandescent bulb replacement. However, before ...

Making it easy to switch street lamps over to LEDs, is the way West Yorkshire’s Harvard Engineering aims to sell LED lighting to councils. It has created the Retro LED family of ‘gear-trays’ which replace the original discharge lamp assembly – be it low-pressure sodium (SOX), high-pressure sodium (SON) or fluorescent. Each assembly is aimed at a particular make and ...

IKEA is investing in Design LED Products, the Scotland-based printable LED lighting firm. IKEA will switch its entire lighting range to the technology by September 2015. The investment by IKEA GreenTech is intended to support Design LED’s development of products that can be used in lighting designs for the home. Based in Livingston near Edinburgh, Design LED creates “light tiles” which are LEDs ...

Last month it was the Sistine Chapel, and now the UK’s National Gallery has LED lighting. “A combination of efficient LEDs and a digital control system has achieved 85% energy savings on lighting. The system’s ability to respond to the changing environment allows the Gallery to make use of available daylight and adjust lighting levels around visiting hours,” said Open ...

Plessey has adopted chip scale packages and wafer level packaging enabling an application specific LED – the AS-LED.

The Sistine Chapel is now lit by LEDs, spectrally matched to excite the pigments used by Michelangelo, Botticelli and other artists working 500 hundred years ago. Since the 1980s, the chapel has been lit from outside through its 12 windows by a mixture of 150W spotlights and 1kW halogen projectors – 66kW in total, according to Osram which supplied the ...
