Light engine for standard dimensions from Samsung LED

The light engine is built on the basis of 80x0,5W LED (PCB dimension 259mmx259mm) which was designed for this application with a CRI higher than 80. Four light engines are put into one complete luminaire and achieve a total lumen output of 3800lm (including the losses of the diffuser). Samsung can offer a power supply which was designed for this product as well. The light engine is available in different CCT from 6.500-3.500K and is offering a binning that is smaller than a 3step McAdams ellipse. This is achieved by a technology transfer from the backlighting of TV LCD panel which is requiring a tolerance of the colour point smaller than 0,005 (u’v’ CIE Diagram). The light engine was designed to achieve over 50.000hrs (MTTF 70%) at an ambient temperature of 50°C which is a more likely ambient temperature than the standard reference temperature for MTTF data of 25°C. Other dimensions and light output values of this light engine are available.
