This capability simplifies the design process for bulb manufacturers

Ikon Semiconductor’s executives will debut reference designs at booth #124. They’ll also showcase the IKS2053, the first product in a series of novel, high-performance, single-stage controllers. The solutions easily match the efficiency of comparative two-stage architectures, but with up to 25 percent fewer components. With broad dimmer compatibility and a compact size, Ikon Semiconductor’s IC offers a better fit for LED high bay light retrofits than larger, more complex solutions currently available.

Commenting on the new technology, Conor McAuliffe, Ikon Semiconductor’s CEO said, “Today, lighting accounts for nearly 20 percent of the world’s electricity consumption. Largely driven by global legislation, inefficient legacy bulbs are steadily being replaced by energy-efficient lighting sources.  LED lighting is the dominant replacement technology.  Retrofit momentum is high, which presents a substantial market opportunity for Ikon Semiconductor.  Added to this, our advanced dim-detect engine enables broad dimmer compatibility – an essential feature in a market saturated with disparate dimmer products.  Our digital solutions represent a significant breakthrough for the solid-state lighting market.”

A key advantage of the Ikon Semiconductor solution is that it eliminates the need for opto-couplers and electrolytic capacitors – standard components that add complexity to the module and can hinder reliability.  This is made possible by the proprietary digital control algorithms in Ikon Semiconductor’s single-stage design. Moreover, the solution allows OEMs to decide the optimum trade-off between the amount of PFC (power factor correction) they need and the amount of ripple the design can tolerate. This capability simplifies the design process for bulb manufacturers, and relieves a further cost burden.  

In a sector dominated by companies that produce AC-DC controller ICs for diverse applications in many markets, Ireland-based Ikon Semiconductor stands out for its singular focus on digital controllers for SSL applications.  Staffed by semiconductor industry veterans, the company’s technology debut is the first event on its roadmap toward producing ICs for the global SSL market.  It is this expertise and focus that attracted venture capital investment to the three-year-old company. According to one investor, Orla Rimmington, operations director of Kernel Capital, "The Ikon Semiconductor solution is simpler, smaller and less costly than the competition, while simultaneously helping our environment by reducing the power consumed through replacing old-style lighting."

LED linear luminaires featured throughout the complex.

Partnering with Greenleaf Energy Solutions, Petty’s Garage installed Cree’s industry-leading LED lighting, featuring Cree TrueWhite® Technology. According to Greenleaf Energy Solutions, when compared with the previous fluorescents, the installation reduces lighting energy usage more than 50 percent and decreases the number of light fixtures needed by 10 percent.

“We know that Cree produces the best LED technology in the world,” said Stephen Moffitt, energy consultant, Greenleaf Energy Solutions. “Cree was the clear choice for Petty’s Garage.”

“Cree LED lighting delivers the quality of light we need for the work in our garage, allowing us to focus on our business of redoing cars,” said Petty. “We turned these lights on, and they made our cars and shop look brand new. There’s really only one word to describe Cree’s lights – wow.”

Cree CR24 LED troffers were installed in the main production facility with LR24™ LED troffers and CS18 LED linear luminaires featured throughout the complex. The next stage of the installation will bring Cree Edge security and floodlights and LEDway® streetlights to the property.

The system allows for up to three configurable

The system allows for up to three configurable, material specific growth modules, enabling high system utilization with multiple researchers simultaneously performing unattended growths and calibrations. This combined with Veeco’s world-class source technology are why the MBE community is choosing the GEN10 across a diverse set of compound semiconductor research applications.

Scientists from the University of Strathclyde in Scotland (United Kingdom) have begun to develop a new Light Fidelity (Li-Fi) technology that will use special micron-sized LED lights, such as those that could be used as part of home lighting or TV displays, to form part of a sophisticated wireless communications network (much like Wi-Fi is today).

The principle, which revolves around manipulating the on/off flicker of LED lights to produce a digital network (a bit like Morse Code from a torch), is not new but most of the other teams are focusing on larger Li-Fi LEDs of around 1mm square in size.However micron sized LEDs not only allow you to use more lights (each of which can act as a separate data channel) but they can also flicker on and off around 1,000 times quicker than the larger LEDs.

Our consumer lifestyle business was margin dilutive to the group, so it was time to decide to move away from consumer electronics," said CEO Frans van Houten during the company's earnings presentation.For the past two years, Van Houten has been focusing on streamlining Philip's operations to highlight profitable divisions such as LED lighting and control systems and hospital scanners.

the same time as providing internet communications and the overall room lighting

But rather than developing Li-Fi LEDs around 1mm2 in size, which other researchers around the world are concentrating on, the EPSRC-funded team is developing tiny, micron-sized LEDs which potentially offers a number of major advantages:

Firstly, the tiny LEDs are able to flicker on and off 1,000 times quicker than the larger LEDs this also means they can transmit data more quickly. Secondly, 1,000 micron-sized LEDs would fit into the space occupied by a single larger 1mm2 LED, with each of these tiny LEDs acting as a separate communication channel. A 1mm2 sized array of micron-sized LED high bay light could therefore communicate 1,000 x 1,000 (-i.e. a million) times as much information as one 1mm2 LED.

Moreover, each micron-sized LED would act as a tiny pixel. So one large LED array display (e.g. used to light a living room, a meeting room or the interior of an aircraft), could also be used as a screen displaying information at exactly the same time as providing internet communications and the overall room lighting.

Professor Martin Dawson of the University of Strathclyde, who is leading the initiative, says: "Imagine an LED array beside a motorway helping to light the road, displaying the latest traffic updates and transmitting internet information wirelessly to passengers' laptops, netbooks and smartphones. This is the kind of extraordinary, energy-saving parallelism that we believe our pioneering technology could deliver."

high bay light is directed away from inkjet heads

The range is purpose-designed for inkjet printers drawing on ITL’s unrivalled experience in this sector being exceptionally lightweight and ensuring exhaust air and high bay light is directed away from inkjet heads and other key platform components.

Available in different system specifications, the SubZero LED comes as a turnkey system - including LED high bay light (one or two), power supply and hi-flex cabling - or the lamp heads alone can be supplied, leaving the integrator to complete the necessary cabling, power supply and other components.

Further user benefit is to be found in serviceability: 30mm modules are replaceable in the field, greatly extending system service life compared to alternative products, with routine maintenance parts restricted to air filters, which are also simple to clean or replace.

ITL sees a ready market for the new SubZero LED. “Market adoption of UV LED curing is clearly growing steadily,” says sales director David Johnson, “and this exciting new product makes integration of this technology far simpler for the platform designer, shortening the learning curve and cutting the time to market”.

whilst improving the shopping experience for their customers

YAHAM Lighting’s team were both professional and knowledgeable right from day one of the project. They caused absolutely no disruption to my business as they were able to install the lighting outside of the store’s opening hours.”

YAHAM Lighting’s Managing Director Tom Harrison said: “We are thrilled that Hillsnews Londis chose LED high bay light to renovate its existing lighting scheme.I am proud to say we are helping them to achieve a 63% cut in their lighting energy bills, whilst improving the shopping experience for their customers.

Although smaller retailers are not affected by the government CRC scheme, it is great to see the more savvy retail business owners and franchisees making significant cost reductions, whilst doing their bit for the environment.Other retail stores to recently purchase lighting systems from MHA Lighting include Tout’s Budgens in Somerset, Mace, Cost Cutter, SPAR and various independent stores.

The event was full to capacity with almost 80 participants. Unfortunately, it was not possible to accept all of the attendance requests. The Forum was organized by the initiators Dr. Fred Grunert (CEO at MAZeT GmbH), Dr. Klaus Schindler (CEO at OptoNet e.V.) and Prof. Dietrich Hofmann (Network Manager at SpectroNet & VisQuaNet).

their incorporation of LED into their design of contemporary pendants

An interesting offering, no doubt, but still missing many features from the Panasonic plasma line, and there are no new LED high bay light models to respond to the behemoths offered by the competition.

 Works with Soraa is a program that will thrive with partnership and collaboration from lighting manufacturers and distributors within the industry. Littman Bros has promoted one of Soraa's launch partners Tech Lighting for over 20 years. Most recently Littman advocates their incorporation of LED into their design of contemporary pendants and other fixtures.

Soraa was founded in 2008 by a team of pioneering professors, it is the world’s leading developer of novel LED bulbs that are built from pure gallium nitride substrates, solid-state lighting technology; according to soraa.com, and the company’s lamps are known to have “superior color rendering and beam characteristics compared to lamps using LEDs created from non-native substrates.”

In a press release from Soraa, it was said that the new Works with Soraa fixture program was created to encourage strong alliances between Soraa and fixture manufacturers, “so fixture and lamp combinations can be rapidly validated for mechanical, thermal and electrical compatibility.” This will hopefully resolve the sometimes opposing relationship between LED lamps and fixtures designed for traditional light sources – incandescent, halogen or fluorescent.

Eric Kim, CEO of Soraa said that this fixture validation program was designed to enable customer-ready fixture-lamp solutions for the LED market and that it is truly a valuable program that will have positive results.
