We bring quality to light. Product highlights Accurate determination of the luminous intensity distribution and luminous flux at LEDs and small LED modules Angular-resolved analysis of spectral and colorimetric quantities Type C configuration with motorized phi and theta axis Compatible with all spectro- meters manufactured by Instrument Systems Data export in IES and EULUMDAT format The compact LEDGON Goniophotometer was specially developed for analysis of angle-dependent spatial radiation patterns from individual LEDs and small LED modules. The entire hemisphere can be measured in the forward direction of the LED. The angular resolution of 0.1° means that exact measured values can be obtained even for narrow-angled LEDs with a high level of reproducibility. Combined with a spectroradiometer from Instrument Systems, all spectral parameters, for example color coordinates or color temperature can be measured as a function of angle. Particularly in the case of white LEDs, these parameters can undergo significant change depending on the observation angle. Knowledge of this characteristic property is extremely important for using white LEDs in illumination technology. light measurement

We bring quality to light. Equipment setup: light-tight without dark room The unit comprises a flat optical bench and a goniometer unit with two angular axes that is mounted at one end of the bench. One of the rotation stages has a hollow shaft where an LED test socket (any socket except LED-850) from Instrument Systems can be mounted. An optical probe is positioned at the other end of the optical bench allowing the distance to the LED to be set at between 5 and 50 cm. Two baffles can be variably positioned at any point to eliminate stray light. 360° in the mechanical axis of the test...

We bring quality to light. Optical probes with diffusers (LEDGON-120 and LEDGON-121), and an optical probe optimized for modules (LEDGON-125) can be supplied for measuring light radiation. The latter is based on a small integrating sphere that allows accurate measurements to be obtained also for test specimens radiating light from an extended surface. Accurate measurements of luminous flux and radiant power The LEDGON 100 Goniophotometer is also ideal for precise measurement of radiant power and luminous flux. Potential measuring errors that can be caused by the geometry of integrating...
