Problems solved by technology

The measurement principle of the goniophotometer is mainly through the inverse square law of illuminance distance, so the distance between the measured object and the optical detector is required to be long enough, which requires a large space and high cost for the goniophotometer; in addition, to realize lamps and The precise measurement of parameters such as the spatial light intensity distribution of the light source must keep the measured object in a fixed ignition position, so the stability of the goniophotometer is extremely demanding
[0003] There are various types of traditional goniophotometers, among which the goniophotometers with high measurement accuracy include reflective mirror goniophotometers, synchronous reflection goniophotometers, rotating mirror goniophotometers, etc., but the measurement methods of these goniophotometers all exist. Some disadvantages: (1) The measurement range is limited, and the same goniophotometer can only measure one or two of the three measurement systems A-α, B-β, and C-γ; (2) The installation method is fixed and flexible Insufficient, limited test function; (3) Large footprint, high cost; (4) Single test function, small scope of application
However, the current robot goniophotometer still has many limitations in the measurement process. It is only suitable for ordinary lamps and light sources, and the test function is single, which cannot meet the measurement requirements of large-scale surface light sources and some complex light sources. Measurement of characteristics under light, measurement of emission characteristics of secondary light sources, etc.
