A light guide performance detection device applied to an LED light guide plate

Abstract

The invention provides a light guide performance detection device applied to LED light guide plates, which relates to the field of light guide detection, to solve the problem that the existing light guide performance detection devices of LED light guide plates cannot measure the different positions of the light guide plate from the light source when in use The light guide performance of the LED light guide plate cannot be driven to adjust for detection, including the main body; the main body is a rectangular structure, and the outside of the bottom of the main body is an inclined structure, the inside of the main body is a rectangular structure, and the inner bottom of the main body is installed. For spotlights, a partition is fixedly installed in the middle of the main body. Two LED light guide plates are embedded inside the moving part, so that they can form a contrast during detection. By manually controlling the lever to move downward, the moving part can drive the LED light guide plate into the interior of the main body, and control the luminance meter to test the LED light guide plate. The light guide brightness at the current distance, by quickly pulling the lever and then pressing it, the moving part can drive the LED light guide plate at different distances to measure the light guide through the luminance meter.

Description

technical field [0001] The invention belongs to the technical field of light guide detection, and more specifically relates to a light guide performance detection device applied to an LED light guide plate. Background technique [0002] During the production process of the LED light guide plate, random inspection and sampling are usually required, and a light guide performance detection device is required during the inspection to detect the light guide performance of the LED light guide plate and whether the LED light guide plate is qualified. [0003] For example, the application number: CN201510383987.4 relates to a light guide plate detection device, which includes a mounting base, a detection platform, a side light source device, a camera bracket, and a camera. The upper surface of the mounting base is connected to a fixed detection platform, a side light source device, and a camera bracket. A fixed camera is connected to the camera bracket, and the detection platform in...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a light guide performance detection device applied to LED light guide plates, to solve the problem that when the existing light guide performance detection devices of LED light guide plates are in use, the detection is usually performed in a place with bright light. , the detection accuracy is reduced, it is impossible to perform convenient detection in a dark environment, it is impossible to detect the LED light guide plate in an environment with different brightness, it is impossible to detect the upper and lower ends of the LED light guide plate in different brightness environments, and it is impossible to detect when the light guide plate is in a different brightness environment. Adjust the brightness inside the device, and when the existing light guide performance detection device of the LED light guide plate is in use, it cannot measure the light guide performance of the LED light guide plate at different positions from the light source, cannot drive the LED light guide plate to adjust for detection, and cannot test the LED light guide plate. The problem of automatic strengthening and fixing when the light guide plate is adjusted and detected
