Metal base CCL substrate for high-power LEDs
Standard indicator LEDs (bulb-type LEDs) have been primarily used with resin substrates (glass cloth epoxy substrates) due to their low heat generation. However, power LEDs used for lighting applications generate more heat, making metal-based substrates effective for improving LED performance and reliability against heat, as well as extending their lifespan due to their excellent thermal conductivity and cost performance.
Well's MCCL substrate is based on a ferrous alloy with excellent heat dissipation, designed to keep the temperature rise of high-power LED elements within a certain range.
By utilizing the ferrous alloy base material as a heat sink, it is possible to significantly disperse and dissipate heat generated from the LED, thereby reducing the heat generated by the LED itself and minimizing the decrease in LED lifespan. Additionally, by combining this with Well's heat sink coated with carbon nanotubes, we achieve further improvements in heat dissipation characteristics, leading to an extended lifespan for the LEDs.
