Smarter LED Street Lighting Applications

Jonathan Catchpole, System Architect/Principal Engineer
TE Connectivity

LED Street Lighting is a technology and infrastructure with evolving demands. It is not only about bringing light to an area anymore, it is about anticipating tomorrow’s needs for value added services. Until recently, designers have mostly only been able to select ANSI/NEMA standard product lines, simply because no specific alternative – or even European – standard existed. Now, working with leading industry partners, TE Connectivity has developed a new connectivity solution for LED street lighting, while at the same time creating a standard for European outdoor luminaires.

Why Bluetooth Low Energy Could be the Key to a Smart Lighting Boom

Saara Guastella, Product Marketing Manager
Casambi

Bluetooth Low Energy is a protocol optimized for controlling smart lighting. It overcomes the drawbacks of communication protocols such as ZigBee and Wi-Fi and can be combined with other technologies to make smart lighting even smarter.  Continue reading

2 oz, or Not 2 oz: That is the Question?

Dr Giles Humpston, Applications Manager
Cambridge Nanotherm 

A variation of this question vexed Prince Hamlet while the modern version unsettles many a LED PCB designer. It’s all about copper thickness. When designing a PCB for LEDs, what weight of copper should be specified? Continue reading

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. Continue reading
