Abstract

The invention discloses a rotary part position recognition device and an optical filter switching device. The rotary part position recognition device comprises a mounting seat, a rotating part and N optoelectronic switches, wherein N is a positive integer which is not smaller than 2; the rotating part is arranged on the mounting seat through a rotating shaft; M groups of light transmitting parts are arranged on the rotating part along the rotating shaft; the M groups of light transmitting parts are different from each other; the M groups of light transmitting parts correspond to the M rotatingpositions of the rotating part respectively; M is a positive integer which is not smaller than 2; the N photoelectric switches are arranged on the mounting seat; the N photoelectric switches jointlyrecognize any group of light transmitting parts; and M is smaller than 2 to the power of N.

Description

technical field [0001] The invention relates to a rotating part position identifying device and an optical filter switching device. Background technique [0002] For the light parameter test of LED, different LED grains need different light attenuation rate parameters, so that the light parameter value of the test is within the reasonable range of test comparison; for this reason, for a LED test equipment, in order to meet the needs of various LED Die testing requirements require a device capable of switching filters. [0003] For multiple filters installed on the rotating part, in order to accurately and timely understand the current use of preset filters, it is necessary to know the position of the rotating part after rotation; corresponding filter. In short, after adjusting the rotating part, the user needs to obtain the currently used filter parameters. At present, there is a manual adjustment of the rotating disk, and the information of the currently used filter can ...
