The invention provides a driving light source adjustment and control circuit for an image detection system. A charging circuit and a boosted circuit are connected between a direct-current power supplyand an adjustable constant-current circuit, the charging voltage input end of the charging circuit is connected with the direct-current power supply, and the battery connecting end of the charging circuit is connected with a battery; the to-be-boosted voltage input end of the boosted circuit is connected with the battery in parallel, the boosted voltage output end of the boosted circuit is connected with the reference voltage input end of the adjustable constant-current circuit in parallel, and the adjusting voltage output end of the adjustable constant-current circuit is connected with a light-emitting diode. The charging circuit reduces the voltage of the direct-current power supply to charge the battery, and the output voltage of the battery is boosted by the boosted circuit to supplypower to the adjustable constant-current circuit and supply power to the light-emitting diode in the image detection system. The adjustable constant-current circuit is connected with a direct-currentpower supply indoors to supply power to work, and, the battery is charged; and when the direct-current power supply is disconnected, the circuit can work by virtue of the battery, thereby improving the convenience of the image detection system and improving the working efficiency.
Description
technical field [0001] The invention relates to the technical field of lighting circuit design for an image detection system, in particular to a driving light source adjustment and control circuit for an image detection system. Background technique [0002] Since the 1960s, there have been many research results in image detection, and the image detection technology for specific problems and applications has gradually developed towards the establishment of general theories. Image detection is closely related to image processing, computer graphics and other research contents, and they overlap each other. However, image processing mainly studies image transmission, storage, enhancement and restoration; computer graphics mainly studies the representation methods of points, lines, surfaces and volumes, and the display methods of visual information; image detection focuses on the description methods of constructing images, and more It is to use symbols to represent various images...
