Description
The technical field is as follows:
the utility model relates to a visual detection light source technical field especially relates to a spotlight type parallel light source.
Background art:
the visual detection means that a machine replaces human eyes to measure and judge, and the visual detection means that a shot target is converted into an image signal through an image shooting device, the image signal is transmitted to a special image processing system, and the image signal is converted into a digital signal according to information such as pixel distribution, brightness, color and the like; the image system performs various operations on the signals to extract the characteristics of the target, and then controls the on-site equipment action according to the judgment result, so that the visual inspection is widely applied to the defect detection of various industrial products. The light source is an important part for visual detection, when the distance between an article to be detected and the detection device is far, the illumination intensity of the existing light source irradiated on the article to be detected is often insufficient, and even if the article irradiated with small size is irradiated, a plurality of light sources are needed to reach the expected illumination intensity.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.
The utility model has the following contents:
an object of the utility model is to provide a spotlight type parallel light source to overcome the defect among the above-mentioned prior art.
In order to realize the above object, the utility model provides a spotlight type parallel light source, including base, sleeve and LED lamp pearl, the base is including connecting outer wall, bottom plate and radiator, one side and the radiator of bottom plate are connected, the opposite side and are connected outer wall connection, the bottom plate is perpendicular with being connected the outer wall, the muffjoint is on connecting the outer wall, LED lamp pearl is connected with the bottom plate, it still is provided with condensing lens one and anti-reflection mirror one to connect the outer wall inboard, condensing lens one overlaps on LED lamp pearl, increase lens one and set up and connecting outer wall oral area, be provided with condensing lens two and anti-reflection mirror two in the sleeve, it sets up in telescopic oral area to increase lens two, the both ends card of condensing lens two is in telescopic inner wall.
The radiator is a grid-shaped radiator.
And a clamping ring is arranged on the outer side of the additional lens and clamps the opening part connected with the outer wall.
Compared with the prior art, the utility model discloses an aspect has following beneficial effect:
the utility model discloses establish condensing lens one at LED lamp pearl overcoat, the illumination that sends LED lamp pearl carries out the spotlight, and illumination after the spotlight is passed out by anti-reflection mirror one, further carries out the spotlight by condensing lens two and assembles into the illumination that is similar to parallel light source through setting up at anti-reflection mirror two of sleeve oral area again and spreads, and illumination is concentrated, intensity is high, and when detection device and determinand distance were far away, the light source still can provide stronger light filling illumination to determinand.
