Description

[0002] During the production process of camera light sources, it is necessary to conduct illumination tests on the factory light sources, including testing the illumination uniformity, maximum illumination value, irradiation range and other parameters of the light source. Since the illumination uniformity needs to be tested, multi-point measurements of the light spot are required. Most existing illuminance meters are handheld illuminance meters that require manual operation and measurement. If the measurement angle is inaccurate, the result of the measured illumination value will also change. The measurement error is large and the error control is difficult. Data entry feedback also requires manual input, which has a low degree of intelligence and is time-consuming.
[0003] At the same time, the traditional handheld illuminance meter testing method has the following shortcomings:
[0004] (1) When testing high-power light source lamps, you need to wear goggles to test each point of the light spot one by one, and it will cause a certain degree of damage to the human eye;
[0005] (2) There are reading errors. In an environment with high light intensity, the naked eye cannot accurately locate the center of the light spot, which places high demands on the accuracy of the test fixture and easily leads to measurement errors.
[0006] (3) It is necessary to record and count the data of each test point, which is a cumbersome, time-consuming and labor-intensive process, and it is difficult to measure and record the light spot as a whole;
[0007] (4) During manual measurement, the measurement data will be affected by the color of the tester's clothing. Utility Model Content
