Researchers of Karlsruhe Institute of Technology (KIT) have developed a novel type of LED street light of increased efficiency. Compared to conventional LEDs, power consumption may be reduced by up to 20%. This will also decrease costs and CO2 emission. Conventional high-power diodes are replaced by a special array of LEDs. This enhances efficiency, increases service life and safety, and produces a better light.
Parallel connection of a large number of LEDs is difficult, as failure of a single diode will cause failure of the overall system or section...
