Problems solved by technology

For the latter method, although the requirements for the luminance meter are relatively low, and the test process may not be carried out in a dark room, it is difficult to automate the whole process of this test method, and the integrity of the test results cannot be guaranteed.
[0003] It can be seen that there are still many defects in the above-mentioned existing long afterglow phosphor luminescent characteristics testing device and testing method thereof, and it needs to be improved.

Abstract

A device and method for automatically testing the luminescent characteristics of long-afterglow fluorescent powder is disclosed. Said device is composed of analog D65 light source, electric shutter, tester, luminometer, illumination monitor, and computer CPU. Its advantages are simple structure, and high correctness.

Description

technical field [0001] The present invention relates to an automatic testing device and testing method for the luminous characteristics of long afterglow phosphors, more precisely the invention of an automatic testing device and a testing method for automatically testing the luminous properties of long afterglow phosphors in the whole process under normal lighting conditions. Background technique [0002] At present, there are two kinds of test devices and test methods that are traditionally used to test the luminous characteristics of long-lasting phosphors: one is to simulate the D 65 The excitation light is projected onto the surface of the sample, and the brightness of the sample is tested with a point-type luminance meter located in the normal direction of the sample. Second, first use the analog D 65 The light source excites the sample, and after the excitation process is completed, the brightness change process of the sample is tested with a contact luminance meter. ...
