Abstract:In this study, composite electroplating technique is used to fabricate the diamond-added copper heat spreader for UV LED applications. Thermal dissipation characteristic and optical performance are improved as the composite diamond-added copper heat spreader adoption. The low thermal resistance of 18.4 K/W with UV LED using diamond-added copper heat spreader was measured. Surface temperature of UV LED using the diamond-added copper heat spreader is 50.42 o C at 500 mA injecting current lower than pure copper h… Show more
