Background light source for color sorter

Abstract

The invention discloses a background light source for a color sorter. The background light source comprises a dimming circuit board, an LED drive and a light emitting body; the light emitting body consists of an LED lamp core for emitting red light, an LED lamp core for emitting green light and an LED lamp core for emitting blue light; the light emitting body is mounted on a circuit board; and the LED drive is respectively connected with the dimming circuit board and the circuit board. The background light source for the color sorter has the following beneficial effects: (1) a reflecting plate is simple in installation, can be debugged in the most proper position by a special engineer before discharging from a factory, has no need to adjust the color, and has no need to mount and adjust by consumers, so that the use by the consumers is more convenient; and (2) the LED lamp core for emitting red light, the LED lamp core for emitting green light and the LED lamp core for emitting blue light emit three colors of light; and through light intensity matching of the three colors of light, any colors can be shown, so that the use is convenient.

Description

technical field [0001] The invention belongs to the technical field of color sorters, in particular to a background light source for color sorters. Background technique [0002] With the continuous technical development of color sorters, the color linear array CCD color sorter system has been used in many industries, such as rice, wheat, corn, plastics, etc., but with the increasing use of industries, color sorters need to choose There will be more and more other types, and more and more colors need to be distinguished. Then, it will be more troublesome to realize it only by the accuracy or algorithm of the CCD of the color sorter. One algorithm for one material is not easy to measure. Therefore, the "background" will play a very good role. It can make the abnormal color of the material more obvious in front of the lens of the CCD camera, making it easier for the algorithm to identify and more convenient for the operator. [0003] However, the background of the current colo...

[0002] With the continuous technical development of color sorters, the color linear array CCD color sorter system has been used in many industries, such as rice, wheat, corn, plastics, etc., but with the increasing use of industries, color sorters need to choose There will be more and more other types, and more and more colors need to be distinguished. Then, it will be more troublesome to realize it only by the accuracy or algorithm of the CCD of the color sorter. One algorithm for one material is not easy to measure. Therefore, the "background" will play a very good role. It can make the abnormal color of the material more obvious in front of the lens of the CCD camera, making it easier to identify the algorithm and more convenient for the operator

[0003] However, the background of the current color sorter mainly has two forms, one is to use a single light source, which is adjusted by changing the color of the background light-emitting board, and the other is to set the background light-emitting board to only have four colors. More limited
