LEDGON - Goniophotometer for determining spatial radiation patterns

The LEDGON goniophotometer from Instrument Systems determines the spatial radiation pattern of LEDs and small LED modules. Measurement is made over the whole forward hemisphere of an emitting LED. A high angle resolution of 0.1° means exact measurements even for narrow emission angle LEDs. In combination with the CAS 140CT spectroradiometer, additional spectral parameters, such as the angle dependence of color coordinates or color temperature, can also be measured. White LEDs, for example, exhibit a significant angle dependence of the color temperature.

LEDGON Goniophotometer

Exact measurements of luminous flux and total radiant power

The LEDGON goniophotometer can also be used for accurate determination of luminous flux and total radiant power. The measurement errors typical of integrating spheres (due to their geometry) are avoided. Instrument Systems has developed an appropriate add-on for the SpecWin Pro software that fully automates the measurement process.
