Abstract
Description
technical field
[0001] The invention relates to a light radiation measuring instrument, which is mainly used for the light intensity distribution or light distribution performance test of various light sources and lamps in various directions, and a synchronous reflection goniophotometer for testing the total luminous flux of light sources and lamps. Background technique
[0002] The distribution of light intensity in all directions in space is an important parameter of light sources and lamps. A goniophotometer is an instrument that accurately measures the distribution of light intensity of light sources and lamps with angles. The existing large mirror goniophotometer usually has two schemes, one is the center rotating mirror goniophotometer, as shown in Figure 1, the optical mirror of this kind of scheme is at the center of rotation during measurement. , while the measured light source moves on the circle around the center of rotation of the optical mirror; the other is a c...
