Heat derivative structure for LED construction, has LED crystals provided on metallic carrier, and base board provided with printed conductor layer, where LED crystals on metallic carrier are connected with conductor layer

摘要

The structure has several LED crystals (4) provided on a metallic carrier, and a base board (1) provided with a printed conductor layer (2), where the LED crystals on the metallic carrier are connected with the conductor layer. A bond wire (41) provides an electrical interconnection with the conductor layer. The base board is made of a composite material with graphite or made of a ceramic composite material, where the LED crystals are provided on the metallic carrier by melting via radio frequency or ultrasound.
