Taiwan-based Everlight Electronics Co Ltd has launched a version of its low-mid-power 5630 package series that attains what is claimed to be record luminous efficiency of 210-220lm/W (at a color temperature of 5000K), as well as a tight 3SDCM ellipse binning for maximum color consistency, suitable for a broad range of professional, commercial and industrial lighting applications. Samples of the 5630 HE KK7D-ELB (0.2W) are available now (for mass production in second-quarter 2016). The existing versions 5630 HE KK5D (195lm/W at 5000K) and KK6D (205lm/W at 5000K) are already in mass production.
Using thermal plastic materials with high reflection, high lifetime and improved optical structures, the 5630 HE KK7D-ELB LED series has been optimized to obtain high optical efficiency without modifying the circuit and PCB layout compared to previous versions, says Everlight. The number of LEDs needed (or the power used) can hence be greatly reduced to save energy for the whole application. For example, a 2000lm linear fixture designed using the 210-220lm/W 5630 HE KK7D-ELB requires less than 12W of power consumption from the LEDs (a 30-40% energy saving compared with comparable existing LED designs).
