Abstract

The invention discloses an infrared lamp control module on basis of a 555 timer and an infrared camera. The infrared lamp control module on basis of the 555 timer comprises an infrared lamp control module and an infrared lamp module; and the infrared lamp control module is electrically connected with the infrared lamp module. The infrared lamp control module on basis of the 555 timer is characterized by also comprising a fine regulating module and a PWM (Pulse Width Modulation) signal generating module, wherein the fine regulating module is electrically connected with the PWM signal generating module; the PWM signal generating module is electrically connected with the infrared lamp control module; the PWM signal generating module comprises a resistance adjustable unit, an electric power storage unit and the 555 timer; the resistance adjustable unit is respectively and electrically connected with the electric power storage unit and the 555 timer to form a multivibrator; the fine regulating module comprises a knob switch; and the knob switch is electrically connected with the resistance adjustable unit. According to the invention, the brightness of an infrared lamp can be manually regulated according to the variation of the environment, the optimal night vision effect can be obtained, and meanwhile, cost of the infrared camera also can be saved.

Description

Technical field [0001] The invention relates to the technical field of infrared lamp control, in particular to an infrared lamp control module and an infrared camera based on a 555 timer. Background technique [0002] In the early security camera infrared light control scheme, the infrared light usually uses a push switch to cut off or connect the power supply. After the power is turned on, the input voltage provides the power supply of the infrared light at a fixed voltage value. The above scheme makes the infrared light The output power of the lamp is high, which wastes power resources. In the existing security camera infrared lamp control scheme, the control of the infrared lamp power is realized by software, and the power of the infrared lamp can be adjusted through the client provided by the camera manufacturer or other methods. Although it is relatively simple to control the power of the infrared lamp through software, the client or other methods provided by the camera man...
