Sericut has introduced a single-sided aluminum PCB as an aid to use efficiently Lumiled power LEDs. Reportedly, by only applying such an aluminum PCB, it is possible to automatically assemble those light-emitting diodes. The challenge: these LEDs can not be exposed to temperatures of over 120°C without being damaged. Thus, wave or convection-forced soldering is not possible, so up to now it has been done manually. With increased operating temperature, the luminous efficiency decreases to a large extent at the same time. The assembly problem has been solved now: aluminum PCB serves as circuit carrier, while an external radiator box warms derivative carriers. According to tests, it was shown that the entire circuit carrier with 12 power LEDs settles down at a temperature of 50°C. Now using these LEDs, it is possible to ensure a perfect heat removal with the use of aluminum plates. From this, the opportunity results that with a limited number of LEDs, capacity is minimized and exceeds a luminous efficiency of up to 1,000 lumens, to date the greatest-known brightness by far.
