The invention relates to the photoelectric field and the visual positioning optical technical field, in particular to an integrated high-uniformity visual light source which adopts the inner periphery to provide 360 degrees without dead angles, and provides a high-end light source which is suitable for the shape of a product workpiece for a high-precision visual positioning system.
Background
In recent years, automation equipment and intelligent technology are rapidly developed and applied to production and life, many automation equipment needs to adopt a visual positioning and visual detection system, and the visual automatic detection system needs to use a light source with high precision and high uniformity to realize the visual positioning and detection with high precision and high accuracy.
Disclosure of Invention
In order to improve the visual automatic fitting precision of the medium-size and small-size parallax barrier gratings and provide a visual image suitable for fitting the parallax barrier gratings with an LCM or OLED display screen for a visual acquisition system, a set of high-uniformity light source is needed, and the defects of the existing light source product are overcome.
In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a grating laminating is with directional light source of high accuracy integration, including integration ya keli support, the radiating circuit board, LED lamp pearl, install the spotlight strip on the support, photoelectric component such as play plain noodles, the radiating circuit board is installed to the inboard periphery of integration ya keli support, LED lamp pearl dress is pasted on the radiating circuit board, evenly distributed LED lamp pearl encloses into confined light emitting source, install even continuous spotlight strip in front of LED lamp pearl, focus LED lamp pearl into parallel high bright light, the play plain noodles has been installed in spotlight strip in front, let the light of focus evenly send, and can protect spotlight strip scratch and damage, wholly constitute the high luminance high degree of consistency light source.
Preferably, the LED lamp beads which are attached to the heat dissipation circuit board and are uniformly distributed form a square uninterrupted light source, so as to form a continuous uninterrupted square light source which uniformly emits light to the inner side.
Preferably, the light-gathering strip is arranged in front of the LED lamp bead, and surrounds into a square uninterrupted light-gathering strip, so that the LED light source is condensed into a square high-brightness uniform light source.
The beneficial technical effects are as follows: the LED lamp beads are focused into parallel high-brightness light rays through the LED lamp beads which are uniformly distributed and arranged on the periphery of the inner side of the integrated acrylic support to form a closed light source and the continuous light gathering strips arranged in front of the LED lamp beads, so that the high-brightness high-uniformity visual positioning light source is integrally formed.
