LuxBox: the incredible shrinking module

As drivers slim down to fit the new, lean LED luminaires, LuxBox announces an emergency lighting module to suit.

Light fixture design has always followed the demands of an intended light source. Regardless of what the fixture looks like, it will always have been designed for a particular kind of light source. For a time, though, it looked as if LED companies had either no confidence in what the LED was capable of, or had simply surrendered to history by making new light sources in all the old lamp shapes.

Happily, we’re seeing that situation change, and a ‘classic’ LED form factor seems to be appearing. It’s flat and shallow – and now it’s time for the electronics that service the luminaires to step up to the crease.

The first ranges of ‘ultra-flat’ drivers are already making their way to market, designed with very small cross-sections to fit into this new generation of LED luminaire. And now it’s time for the emergency lighting sector to come to the party. LuxBox is announcing a new range of emergency modules to work alongside the new drivers.

The new UltraSlim from LuxBox is designed specifically to fit into slimline LED luminaires. Having a depth of only 11mm, it sits comfortably with the new ultra-flat drivers. As would be expected with LuxBox, the new modules have been designed out of the many years of expertise within the company. Wherever possible, components have already been tried and tested in LED driver circuits, particularly exploiting the knowledge that’s been gained in the production of LED retrofit tubes, where similar physical conditions pertain. And, where necessary, components specific to emergency lighting circuits (transformers and inductors) have been designed to fit into the available volumes of the new module – no mean feat in itself.

LuxBox has not shied away from a bit of controversy. The issues that have beset lithium batteries may have been overcome – the latest LiFePO4 (lithium iron phosphate) technology is already available in LuxBox’s other new emergency ranges. But, for the time being at least, LuxBox is sticking with conventional NiCd batteries (AAA cells) for this application.

This is a case of the module manufacturer being ahead of the battery developer. Once the LiFePO4 battery manufacturers catch up and can provide cells with sufficient capacity to ensure constant output over the required duration, there may well be a change – but until then, it’s sensible to stay with the reliable technology.
