A light source module that is easy to adjust

Abstract

This invention discloses an easily adjustable light source module, including a fixed plate, an adjusting housing, a connecting housing, and an angle adjustment mechanism. Several adjusting housings are evenly distributed along the edge of the fixed plate and are rotatably connected to the fixed plate. A connecting housing is fixed to the top of the fixed plate, and the adjusting housing is connected to the connecting housing via the angle adjustment mechanism. Several LED light strips are disposed inside the adjusting housing. This invention uses a drive mechanism to rotate a threaded rod, which in turn moves a drive block. The drive block pushes or pulls an adjusting seat via an adjusting plate, thereby causing the adjusting housing to rotate up and down. This adjusts the illumination angle of the LED light strips and keeps the angle consistent, allowing objects to exhibit different lighting effects at different angles, improving image quality and thus enhancing image acquisition.

[0002] Machine vision is often used for product quality inspection in mass production processes, especially in dangerous environments and where human vision cannot meet the requirements. The input of a machine vision system is generally an industrial camera, and the lighting system is an important factor that affects the image acquisition of the industrial camera.

[0003] Patent CN102980103A provides a machine vision LED lighting source, including a base, a matrix light source assembly installed on the base, the matrix light source assembly includes two brackets and an LED matrix light source movably installed between the two brackets, the number of matrix light source assemblies is 10, and they are installed on the base in an equilateral decagon, the LED matrix light source is connected to the controller, and a diffusion plate is provided on the irradiation surface of the LED matrix light source. The light is made uniform by the diffusion effect of the diffusion plate. Compared with the existing ring light source, richer brightness and incident angle can be obtained without moving the lampshade, and the light is uniform, so that it can adapt to more applications. However, this technical solution cannot change the angle of the light source and keep the angle consistent, resulting in poor image acquisition effect. Summary of the invention

[0004] The main purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art and to provide a light source module that is easy to adjust.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A light source module that is easy to adjust, comprising a fixing plate, an adjustment shell, a connecting shell and an angle adjustment mechanism;

[0007] A plurality of adjustment shells are evenly distributed on the edge of the fixed plate, and the adjustment shells are rotatably connected to the fixed plate; a connection shell is fixedly arranged on the top of the fixed plate, and the adjustment shells are connected to the connection shells through an angle adjustment mechanism;

[0008] A plurality of LED light strips are arranged inside the adjustment shell.

[0009] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0010] 1. The present invention drives the threaded rod to rotate through a driving mechanism, and the threaded rod drives the driving block to move when rotating. The driving block pushes or pulls the adjustment seat through the adjustment plate, thereby driving the adjustment shell to rotate up and down through the adjustment seat, thereby adjusting the illumination angle of the LED light bar and keeping the angle consistent, so that the object presents different lighting effects at different angles, which can improve the imaging quality and thus improve the image acquisition effect.

[0011] 2. The present invention drives the first winding roller to rotate by rotating the first driving motor, and the rotation of the first winding roller is used to retract and release the color temperature gradient film. By placing areas of different colors on the color temperature gradient film on the front of the LED light strip, the color of the light is changed, and then the color temperature is adjusted. The color temperature sensor is used to monitor the color temperature of the current state in real time, and the controller is connected to the device terminal through the built-in WiFi signal transceiver to display the color temperature data on the remote device in real time. The staff can adjust the color temperature of the device according to the current color temperature information. BRIEF DESCRIPTION OF THE DRAWINGS
