110 TECHNOLOGY / LED
Philips Affinium LED freezer lighting saves 60% in energy costs for Tesco. The fixtures are a ‘peak design’, specifically for freezer lighting applications.
plies drivers and cables, provides detailed technical design-in guides and recommends other component suppliers for items like reflectors and thermal solutions, and say a system warranty for five years for instance, then the luminaire manufacturer has all the means and comfort he needs to launch a great LED fixture portfolio that will stand the test of time.
I am concerned by people who say they are concerned about the module approach. They may think the module approach is about squeezing a new technology into an old format. In fact I think they might be missing the point or have a different agen- da. A modular approach helps to future- proof a design and offer design freedom. We know that LED technology is improving at a fast rate, so if a luminaire is designed to- gether with its LED board and electronics as an inseparable unit, a peak design, then the LED technology inside that luminaire quickly becomes out of date. If the luminaire maker tools up for a modular approach, and the module technology improves every six months, then there is no need to retool the fixture line to upgrade the light source to the next generation. And as the light source
supplier innovates and releases better and better module and system technology, that innovation is passed on to its customers, the luminaire manufacturers, for no extra cost. How good is that?
Kristian Krogh, co-founder of EQ2light, a London-based lighting design company with global clients, comments: “Our customers are becoming increasingly aware of LED and the advantages of LED schemes. Toughening energy legislation and smart salesmen have led them to LED for some years. However, as some of these older installed schemes mature, some have shifted (in colour) and malfunctioned. So whilst many of our customers are still open to LED schemes most are not intending to wed themselves to one manufacturer for the next ‘50,000 hours’. They are therefore keen to have the opportunity to replace the LEDs with an- other manufacturer’s units if this becomes necessary.”
Krogh summarises: “Modularity will start to offer this possibility, whilst we are perhaps not quite there yet, the idea that we can swap units as simply as swapping a Decostar for a Masterline is not only appealing but necessary. This will offer the ‘apples for
apples’ comparison and start to eek out the less factual manufacturers, turning the wild west LED revolution into an understandable and accountable market place for lighting professionals as well as end users.”
STANDARDISATION?
It is clear there is no standard industry method of getting the LED light source into a luminaire, either in existing entrenched form factors or new form factors. Everyone is doing it in their own way. Some manu- facturers take into account that a lighting designer or consultant will have to try and specify his luminaires and his technology, others may not even consider these things. To help with this, some companies like Philips offer a design-in support service, through an application engineering support team. These teams also have expertise and growing experience of other adjacent tech- nologies, like diffuser materials, thermal management and optical designs. Although the manufacturers of the light source technologies can help to a point, the luminaire manufacturers now have to step up to the plate and innovate using LEDs – that means LED lamps, LED modules and in
