Description

Technical Field

[0001] The utility model belongs to the field of liquid crystal panel detection, and in particular relates to a camera supplementary light source structure. Background Art

[0002] The LCD panel is the material that determines the brightness, contrast, color, and viewing angle of the LCD display. During the panel production process, the color filter and TFT glass will be attached to both sides of the liquid crystal. This process requires precise alignment, so MARK points are made on the upper and lower glasses. The bottom is illuminated by a fill light source at the MARK point, and the upper CCD is used to capture the image to ensure that the upper and lower MARK points are in a coincidence state. However, the luminous surface of a general light source is uneven, and the color of the MARK point is different for different LCDs. If the color of the fill light source is close to the color of the MARK point, the edge of the MARK point will be blurred when taking pictures, making it difficult to locate. Utility Model Content

[0016] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0017] like Figures 1 to 3 As shown, a camera supplementary light source structure of the present invention includes a shell, at least one side of the shell is provided with an opening, a light source circuit board 2 is provided in the shell, and the light source circuit board 2 is provided with an array of LED lights 3 and resistors 4 facing the opening. The LED lights 3 and the resistors 4 are connected in series or in parallel according to different needs. The LED lights 3 can emit at least two light sources, red and blue. By selecting red and blue LEDs, the lens can emit red or blue light to meet the different light source color requirements of the liquid crystal panel production process. The resistor 4 plays a current limiting protection role. A diffuser 5 is provided at the opening, and the light is dispersed through the diffuser 5 to achieve high uniformity without dark areas.

[0018] The shell includes a shell 1 with a concave cross-section and end covers 6 arranged at both ends of the shell 1 in the longitudinal direction. One of the end covers 6 is provided with an outlet hole 7 for the power cord of the light source circuit board to pass through. The outlet hole 7 is used to connect the end cover 6 and the shell 1 by screws. The screw connection structure is stable and easy to disassemble, which is convenient for subsequent maintenance or replacement of accessories.

[0019] Reflectors 8 are provided on both inner side walls in the width direction of the shell 1. The reflectors 8 are connected to the shell 1 by screws. Reflective sheets 9 are attached to the surfaces of the two reflectors 8 facing each other. The reflective sheets 9 have a high reflectivity, reduce light consumption, and improve overall brightness.

[0020] The reflector 8 and the end cover 6 are surrounded by a groove 10 for fixing the diffuser 5. The diffuser 5 is fixed by the groove 10. In addition to fixing the diffuser 5, the horizontality of the diffuser 5 can be ensured, making it less likely for the diffuser 5 to tilt and cause uneven light output.

[0021] A heat conducting plate 11 is provided between the bottom surface of the light source circuit board 2 and the housing 1 to achieve rapid heat dissipation through the heat conducting plate 11, thereby reducing the temperature and avoiding short circuits and open circuits caused by heating due to long-term use.

[0022] The two end covers 6 are each provided with a first card slot 12 on the side facing the light source circuit board 2, and the light source circuit board 2 is positioned by the first card slot 12. The first card is parallel to the groove 10 on the end cover 6, so that the light source circuit board 2 and the diffuser plate 5 remain parallel, and the light distribution is more uniform. The inner side of the bottom of the reflector 8 is provided with a second card slot 13 for pressing the light source circuit board 2, and the light source circuit board 2 is pressed and fixed by the second card slot 13.
