DLC PCB For High Brightness LED's
HeaThru-LED is a revolutionary PCB technology based on DLC (diamond-like carbon) films; ADS's innovative thermal product is designed for next generation high-brightness LED products. DLC is a highly thermal conductive material that has much higher heat dissipation performance than conventional MCPCB substrates which rely on an insulation layer (epoxy/fillers) that is thermally insulating as well. The most significant performance advantages of HeaThru-LED is superior thermal spreading and thermal conductivity, which at 475 W/mk is 100-times higher than conventional MCPCB fillers. This results in significant improvements on the lifetime, reliability, stability, and light intensity achievable for LED lighting products. You can find our brochure here: ADS English HBN Brochure.


Below find a graph showing achievable chip temperatures of our prototype DLC PCB compared to traditional MCPCB packaging. Our newest samples, just produced, offer up to 4X the thermal conductivity of the test below.



Note that the amount of light intensity achievable increases dramatically with our DLC product; some colors achieve even higher results. Again, our latest samples can reach much higher lumens.
