This new range represents a major breakthrough in LED lighting

The new LED Reflectors are available as direct replacements for GU10, Par 16, Par 20, Par 30 and AR111 type halogen lamps ranging from 35W to 75W, and offer significant savings in installed electrical load as well as energy consumption. Initially they will be available with GU10, SES, and E27 fitting arrangements, with additional new formats to follow shortly.With a rated life of 20,000 hours there are also considerable savings possible in replacement costs. Megaman claim that the average cost of ownership shows a payback in under 4000 hours operation, making a change from traditional halogen spotlights to LED Reflectors now very affordable and sensible for the environment.The Technicalities.

The clever design of these lamps is based around an innovative vertical array of LEDs mounted back to back to generate as much of a point source as possible within the reflector, thus increasing efficiency and light output. So these lamps are very bright, and offer a colour tolerance of just 100K shift in colour temperature – compared to an average of 800K for most other LED based lamps.Another common problem with existing LED-based lamps – heat generation – has been overcome by incorporating a patented heat sink arrangement (called TCH - or Thermal Conductive Highway). They therefore achieve outstanding heat dissipation – in fact the LED chip can be touched by an unprotected finger during operation without danger of burning. The very light weight of the heat sink arrangement also means that the lamp will not tilt when installed in track spots. MD of Megaman’s UK operation believes that the company’s new LED Reflector Range will meet a huge international requirement for very low energy lamps.

“This new range represents a major breakthrough in LED lighting, as it solves a number of key issues that have so far limited the take-up of these light sources in consumer applications. The result is that we have minimised energy consumption and heat generation, while maximising operational life and delivering three times more light output than other LEDs for the same wattage. We think they are going to be very popular replacements for halogen bulbs.The newly launched models can drive up to four LEDs for displays on portable applications with only one LED driver and MAP1042 has a stronger power control function with dual LDO built in than the other model. In the wake of its first launch of LED drivers for portable applications this time, Magnachip plans to reinforce its presence in the power semiconductor market by further expanding to the LED driver markets for notebooks and TVs down the road.
