New SPECTRALUX light engines from OMC able to deliver 130 lumens/watt

OMC have launched new series of light engines which offer very high luminous efficiencies which the company says is up to 30 per cent higher than alternatives currently available. The 220-series SPECTRALUX light engines are able to deliver up to 130lm/W and feature life expectancies of up to 40 years.

In the SPECTRALUX light engine range, highly efficient, tightly-matched LED die material is bonded to a thermally conductive substrate and encapsulated with a precision-applied phosphor coating. OMC is able to achieve the high performance in the 220-series because the company uses a greater LED chip area which has been optimally distributed across the substrate surface to enhance optical efficacy and reduce current density.

In addition, the electronic configuration of the die elements has been arranged to keep drive currents low, thereby reducing the power dissipation further. Not only does this technique result in high luminous efficiency, it also ensures that heat is spread more effectively across the substrate surface resulting in lower junction temperatures and longer life expectancy. In applications where very high efficiency is not the main consideration, the die area can be tailored to reduce power consumption or cost so as to meet the requirements of individual customer applications.

The 220-series devices are compact at only 20mm square, and are simple to use, requiring only a constant-current supply to drive them. Heatsinking the devices is also more simple as the greater efficiency means lower power dissipation for a given light output. Comments William Heath, OMC”s commercial director: “100lm/W has been a benchmark figure for exceptional light engine performance for some time now so to have achieved 130lm/W in our new 220-series devices is very exciting. They are suitable for a very wide range of applications, from lighting fixtures/luminaires to house, caravan, and boat illumination, cabinet and display lighting, industrial machinery, vending machine, chillers, photographic flashes and microscope illumination.”
