Problems solved by technology
[0003] When the traditional detection method is tested by personnel, it is often due to different judgment standards of personnel, or the influence of environmental factors and other factors, resulting in misjudgment results such as color misjudgment, brightness misjudgment, quantity misjudgment, etc.

Embodiment Construction
[0038] Please refer to figure 1 According to an embodiment of the present disclosure, the light-emitting element detection device 20 is optically connected to at least one light-emitting element 41 of an object under test 4 to detect the light-emitting element 41 . The light-emitting element testing device 20 includes a dark box 2 , a slide rail 21 , a camera device 22 , a light-incoming plate 24 and a processor 1 .
[0039] The slide rail 21 is arranged in the dark box 2 . The camera device 22 is arranged in the dark box 2 and slid on the slide rail 21 . In this embodiment, the dark box 2 is a hollow cuboid, and the slide rail 21 is arranged on the inner bottom surface of the dark box 2 and is parallel to the long axis of the cuboid. The camera device 22 can move along the direction parallel to the long axis of the cuboid inside the dark box 2 through the slide rail 21 .
[0040] The light inlet plate 24 is disposed on one side of the dark box 2 and has at least one hole 2...

The invention discloses a light-emitting element detection device. The light-emitting element detection device is optically connected with at least one light-emitting element of an object to be detected. The light-emitting element detection device comprises a camera obscura, a sliding rail, a camera device, a light inlet plate and a processor. The slide rail and the camera device are arranged in the camera obscura. The camera device is slidably arranged on the sliding rail. The light inlet plate is arranged on one side of the camera obscura and provided with at least one hole optically connected with the light-emitting element. The camera device is aligned with the light inlet plate to extract an image of the light inlet plate. The processor is coupled to the camera device and is used for obtaining an RGB value of the image corresponding to the light-emitting element, converting the RGB value into an HSV value and judging whether the light-emitting element of the object to be detected meets a preset standard or not according to the HSV value. Whether the light-emitting element to be detected meets the preset standard or not is automatically judged through the image shot in the camera obscura, and misjudgment possibly caused by the influence of different judgment standards or environmental factors of operators is greatly reduced.
Description
technical field [0001] The disclosure relates to a light-emitting element detection device, in particular to a light-emitting element detection device that introduces the hue purity of light-emitting diodes and implements an intelligent color-mixing identification system. Background technique [0002] The traditional light-emitting diode (LED) test uses a simple test fixture to connect the product to the power supply and turn it on. The optical fiber in the fixture transmits the light source to the display panel of the fixture, and then the personnel conduct a visual inspection to determine whether the product is normal. . The detection items include the number, color and brightness of LEDs. [0003] In the traditional detection method, when personnel are tested, it is often due to different judgment standards of personnel, or the influence of environmental factors and other factors, resulting in misjudgment results such as color misjudgment, brightness misjudgment, and qua...
