710788SafeledClosedGRD Proof of ConceptInnovate UKWhilst AC LEDs are common in homes and offices, heavy industry and specialist commercial organisations use DC LEDS. DC LEDs are heavy because of their drivers and these drivers are often prone to failure resulting in a reduced LED lifespan and/or increased maintenance scheduling and costs. This is often aggravated due to the height, remoteness or hazardous location of the lights. Since 2013, we have supplied high gantry lights for container cranes and hoists in ports and oil and gas platforms in the UK and USA. We carried out market research with the quarrying and below ground mineral extraction industries i.e mines and tunnelling and found that organisations already using DC LEDs expressed a need for lighter LEDs with greater reliability and less complexity for easier installation and maintenance; easier to move and manhandle in confined spaces with more focus on safety, particularly damage from debris and reduced risk of fire and explosion. Many of these industries use traditional metal halide and SON lights but are often resist LEDs because of their higher initial cost, even though their Sons and MH regularly fail because of vibration issues. Therefore, Constellation lighting is keen to prove the concept of a modular AC powered LED (no driver required) with an integrated hardwired PCB. This would significantly reduce the weight and complexity, and hence improve installation time and ‘in service’ life. A sealed explosion proof lens would enable the LED to be used in hazardous and confined spaces. We aim to produce a module weighing ~1.5Kg producing ~60W, that can be joined to other modules to create a range of ‘bespoke’ lighting solutions. We aim for a competitive manufacturing price, which would result in a very competitive sales price when compared to traditional and other LED lighting systems. The system would be called SafeLED.
