Light engines deliver 130 lumens per Watt

3 April 2013 Opto-Electronics

OMC has launched new light engines which offer very high luminous efficiencies of 130 lm/W and feature life expectancies of up to 40 years.

In the SPECTRALUX 220-series, 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 such high performance 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 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 20 mm square, and are simple to use, requiring only a constant-current supply to drive them. They are suitable for a 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.
