LEDs Under the Thumb

Dr Giles Humpston, Applications Manager
Cambridge Nanotherm 

LEDs do two things really well. They emit light and heat, in roughly equal measures. The light is generally useful, the heat less so. Heat and LEDs do not make good bedfellows so when designing a solidstate light source, as much care needs to be taken in removing the heat as managing the photons. Continue reading

The Lighting Industry Today, Tomorrow and Beyond, an Interview with LIA President, Peter Scott

What would be your prediction for lighting in 10 years’ time?
Majority of commercial members won’t be supplying commodity type luminaires but in order to prosper will need to adapt to the need for more specialist products or add value through other features. Only recently we had a dinner for Past Presidents of the association and we discussed LiFi, data driving the industry, smart cities, leaving the EU and a new dawn in global politics. Many of the companies such as Google did not even exist when some of the past presidents were in office and it was a conversation only five years ago we would we never have expected to be holding.

How Many Engineers Does it Take to Change a Lightbulb?

Kelly Blount, Marketing Associate
Mintek Corp.

The question is silly yes, but it could help determine if your facility is spending too many man hours on an asset that doesn’t need to be attended to as often as it could be in turn saving your facility on labor costs year over year. Continue reading

Coupled Thermal-Electrical Simulations Shed Light on LED Performance

Pier Angelo Favarolo and Lukas Osl – Zumtobel Group
Sabine Goodwin and Ruben Bons – Siemens PLM Software

Light Emitting Diode (LED) manufacturers sort their products into “bins” based on forward voltage, with the purpose of delivering the most consistent light possible. Despite the tight grouping of forward voltages in these bins, manufacturing tolerances continue to lead to significant variations in both current draw and temperatures inside the LEDs, resulting in a range of colors, even within the same batch.

Retailers Light up the Holidays with LEDs

Jay Black, VP of Development & Communications
Revolution Lighting Technologies

‘Tis the season for festive lighting, longer store hours and everyone’s favorite, costly energy bills. Retailers know this struggle all too well as the combination of extra lighting displays and energy needed to keep stores open longer often results in added energy costs building up between the months of November and January. The holidays can put a damper on energy expenses but it is possible for retail facility managers to cut costs while keeping stores ‘merry and bright’ with the help of solid-state LED lighting solutions. We’ve seen LEDs take over the holiday light sections with strands of colorful LED lights giving off a brighter glow, but where the real energy savings come from is a store’s overhead lighting, and LEDs offer the best solution for reducing energy costs.

Big Will not be Bad, but Will be Necessary in IoT

David L. Bay, LC
OSRAM Americas

Intelligent energy is all about managing energy more efficiently than ever before. Demand for energy keeps growing worldwide, and the use of it must become more sustainable. At the same time there is a growing need for an expansion and modernization of the existing energy infrastructure. This will require a systematic optimization of the energy system, and today’s power grids will gradually transform into interactive, transparent and environment-friendly smart grids, often interconnecting regions, countries or even continents.”  Continue reading

Six Biggest LED Lighting Myths

Arthur Smith, LEDwatcher.com

Light emitting diodes or LEDs for short are quickly gaining popularity, because right now many companies are offering huge variety of LED products. But just like with any new product, LED lighting also has to deal with judgment and concerns from the consumers, who don’t believe, that these lights could be as efficient as their manufacturers claim them to be. So let’s look as some of these worries and find out, why they are just myths. Continue reading
