According to IESNA-LM-79 standard, Goniophotometer is used for light intensity distribution and flux test. Accordingly, Lisun Group introduced several different types Goniophotometer, the following introduces its characteristics and application.
Lisun LSG-5000 LM-79 Goniophotometer with Rotating Mirror is an automatic light distribution intensity 3D curve testing system. It can realize C-γ, A-α and B-β measurement solution. The measuring distance is from 5m to 30m. It can measure all types of lighting sources, LED or HID luminaries such as indoor and outdoor luminaries, roadway luminaries, street lamps, flood lights and other kinds of luminaries.
Lisun LSG-1950/LSG-1950S Goniophotometer for Automotive and Signal Lamps is mainly used to measure transportation industry luminaries such as traffic signal lamp, public transport, train and space ship luminaries. The photometer head keeps static and faces to the teat sample while the test samples rotates around both horizontal axis and vertical axis, so the luminous intensity and illuminance of the tested lamp or luminaires can be tested.
Lisun LSG-1800B/LSG-1700B/LSG-1600B High Precision Rotation Luminaries Goniophotometer carries out measuring methods of fixed location and rotating luminaries. It can work by double pillars structure and single pillar structure to realize C-γ, A-αand B-βmeasurement solution, it fully meets CIE, IEC, LM-79, GB etc standards. LSG-1800B adopts Japanese Mitsubishi Motor and German Angle encoder System to keep the test accuracy to 0.0017degree. It is widely used in optical industry laboratory. It is used to test for LED street luminaries, indoor luminaries and mining luminaries’ photoelectric parameters.
Lisun LSG-1800BCCD/LSG-1700BCCD/LSG-1600BCCD High Precision Rotation Luminaries Goniospectroradiometer except used in industry laboratory to test LED street luminaries, indoor luminaries and mining luminaries’ photometry parameters such as space light intensity distribution curve, Luminous intensity data, zonal luminous flux, luminaries efficiency, luminance limitation curves and electric parameters such as voltage, current, power, power factor and frequency. It combines a CCD spectroradiometer to test spatial spectral color parameters. The test data can be saved as IES, LDT, CIE etc file document. This kind of format files can be transferred by other illumination and luminaire design software such as DiaLux.
Lisun LSG-1200A Compact Goniophotometer has included a 1m dark room; it is used to measure the luminous intensity distribution curve, intensity data, spread angle and other parameters for Chip LED, LED Module, LED Bulb, LED spotlight and CFL Lamp. LSG-1200A can measure the maximum size 180mm lamps.
