High-precision photochromic electrical automatic tester

Abstract

The invention belongs to the technical field of light source testing, in particular to a high-precision photochromic electrical automatic tester comprising an instrument measuring system and an integrating sphere connected by a signal line, wherein the top of the integrating sphere is provided with a driving rod, mounting seats are respectively disposed on the top of the integrating sphere, on thebottom of the integrating sphere and on the driving rod, the mounting seats are internally provided with unlocking discs, two driving blocks are provided on the surface of the unlocking discs, two first storage slots are defined in the wall thicknesses of the top of the integrating sphere, and first springs are provided in the first storage slots. The high-precision photochromic electrical automatic tester, by setting three mounting seats, can make one of them in a testing state, one of them in a cooling state and one of them in an installation state of a new light source, and can maximize the use of period of time of the lamp source cooling after the test and improve the test efficiency. At the same time, disassembling the lamp source after cooling can avoid the leakage accident caused by the breakage of the lamp source when the lamp source is disassembled.

Description

technical field [0001] The invention belongs to the technical field of lamp source testing, in particular to a high-precision automatic tester for light, color and electricity. Background technique [0002] Integrating sphere is a hollow sphere whose inner wall is coated with white diffuse reflection material, also known as photometric sphere, optical flux sphere, etc. One or several windows are opened on the wall of the ball, which are used as light inlet holes and receiving holes for placing light receiving devices. The inner wall of the integrating sphere should be a good spherical surface, and it is generally required that its deviation relative to the ideal spherical surface should not be greater than 0.2% of the inner diameter. The inner wall of the ball is coated with an ideal diffuse reflective material, that is, a material with a diffuse reflectance close to 1. The commonly used material is magnesium oxide or barium sulfate, which is mixed with colloidal adhesive ...

AI Technical Summary

Problems solved by technology

[0003] When testing the light source, it is necessary to open the integrating sphere, then install the light source inside the integrating sphere, then turn off the integrating sphere, after testing the light source, open the integrating sphere to take out the light source, and install according to the same action The efficiency of the new light source is low for the next test. At the same time, due to long-term use, the internal temperature of the integrating sphere is high. When people take the light source with high temperature, it is easy to cause danger. In view of this, the present invention provides a A high-precision photochromic and electrical automatic tester, which can greatly improve the test efficiency, and at the same time can well reduce the impact of high temperature on testers
