Introduction The near-field goniophotometers of the series RIGO 801 measure luminous intensity distributions, ray data, luminance distributions and spectral data of LEDs up to large luminaires. The measurements are enabled through a camera-based measuring technique in the case of which a luminance measuring camera is moved around the object to be measured, with the measuring distance being small. Thus, particularly compact measuring systems can be realized. The luminance images recorded by the measuring camera are transformed into ray data widely used in optical simulation. The ray data are...

For measuring photometric data, various goniophotometer systems are used. Fundamentally, a distinction is made between farfield and near-field goniophotometers. In the case of far-field goniophotometers, the photometric receiver/s is/are positioned at a large measuring distance beyond the photometric limiting distance. Near-field goniophotometers like the RIGO 801 series use a measuring camera positioned at a short measuring distance. They measure ray data and luminous intensity distributions (far-field data). Concerning the structure of the goniometer units, the standards (CIE 121-1996,...

Luminaire and lamp measurement For measuring large luminaires, the series of our type-C luminaire goniophotometers have been designed. Different standard systems for measuring DUT with diameters of 1400 mm, 1500 mm, 1800 mm and 2000 mm are available. All common types of luminaires, lamps and LEDs can be measured. Measurement of luminous intensity distributions and luminous flux of small lamps/LEDs up to large luminaires in one goniophotometer User-friendly alignment by means of the measuring camera Short measuring times and high angular resolutions (typical measuring times and angular...

Ray data describe the complete radiation characteristic of a light source and are often used for simulating optical components. In many cases, ray data derived from mathematical / physical models describe the real light sources insufficiently, which makes measured ray data indispensable for the realistic simulation of optical components. For measuring the ray data of LEDs and lamps, the smaller goniophotometer models have been designed. The result data can be output in all common ray data formats by means of a conversion program free of charge. Alignment of the objects to be measured by...

Measurements according to the Zhaga standard TechnoTeam Bildverarbeitung GmbH is The Zhaga consortium develops specifications for the mechanical, photometric, thermal and electrical compatibility of interchangeable LED modules and ballasts. The photometric specifications also require the evaluation of imageresolved luminances. Thus, it can be said that the RIGO 801 near-field goniophotometers are ideally suited for this purpose. Measurement of the luminous intensity distribution and of the luminous flux of Zhaga modules Evaluation of the luminous intensity distribution Evaluation of the...

Spectral ray data For the physically correct simulation of dispersion effects, ray data must be spectrally resolved. As it is not possible to acquire image-resolved spectral data at reasonable expense (hyperspectral camera), the whole spectral range is split up into some few ranges by means of suitable spectral filters. For these ranges, ray data are measured separately, and spectral ray functions are assigned. This approach has proved to be successful particularly in the case of white LEDs. RIGO 801 goniophotometers can be equipped with a filter wheel camera (equipment with color filter...

RIGO 801 LED Type C goniophotometer for LEDs and modules of a diameter up to 200 mm The smallest goniophotomter of our product range is a compact desktop unit designed especially for measuring the ray data of small light sources, in particular of LEDs and LED modules of a diameter up to 200 mm. The object to be measured is mounted on a vertical rotary axis (phi). The camera and the other sensors, which are mounted on an arm, move around the measurement object on a circular arc (theta axis). The light source is positioned by an x/y/z translation stage which displaces the upper rotary axis....

RIGO 801 300 Type C goniophotometer for LEDs, lamps and small luminaires of a diameter up to 300 mm This free-standing type C goniophotometer has a maximum measuring volume of a diameter of 300 mm, and is well suited for measurement objects ranging from LEDs up to small luminaires. The measuring camera and the other sensors being mounted on two axes linked with each other are moved on a spherical surface around the stationary object to be measured. The goniometer is mounted in an external frame in an entirely pivotable manner so that vertical just as horizontal burning positions can be set....

RIGO 801 600 Type C goniophotometer for LEDs, lamps and small luminaires of a diameter up to 600 mm This free-standing type C goniophotometer has a maximum measuring volume of a diameter of 600 mm and is well suited for measurement objects ranging from LEDs to small luminaires. The measuring camera and the other sensors mounted on two axes linked with each other are moved on a spherical surface around the stationary object to be measured. The high accuracy of the ray data measured (< 0.1 mm) allows the ray data measurement of light sources of a size from a power LED on (chip surface area...

RIGO 801 luminaires Type C goniophotometer series for measurement objects of a diameter up to 2000 mm The large goniophotometers can be employed for measuring LEDs up to large luminaires. They are available in different designs. The currently available standard designs (diameter of measuring volume) are 1400 mm, 1500 mm, 1800 mm and 2000 mm. The kind of device to be chosen mainly depends on the product range to be measured and on the size of the available laboratory room. Customized designs are possible at corresponding additional costs. The goniometer mechanics includes an external,...
