Abstract: High-power light-emitting diode (LED) efficiencies are strongly dependent on device type and operating conditions. Electrical and optical power measurements are performed on five commercially available phosphor-white LED types for a number of independently enforced forward currents and junction tem-peratures. The experimental results allow for a comparative evaluation of dominant loss mechanisms and their current and temperature dependences.
