This part of IEC 60747 specifies the terminology and the measuring methods of various efficiencies of single light emitting diode (LED) chip or package without phosphor. White LEDs for lighting applications are out of the scope of this part of IEC 60747. The efficiencies whose measuring methods are defined in this part are the power efficiency (PE), the external quantum efficiency (EQE), the voltage efficiency (VE), and the light extraction efficiency (LEE). To measure the LEE, one needs the measurement data of the internal quantum efficiency (IQE), whose measuring method is discussed in the other two documents. The injection efficiency (IE) and the radiative efficiency (RE) are described for definitions only.
