Abstract

The invention discloses a surge protection-based flickering-prevention table lamp control system. The surge protection-based flickering-prevention table lamp control system is characterized by mainlycomprising a time-based chip U, a bidirectional thyristor VS and a diode D6, wherein a P pole of the diode D6 is connected with ground, and an N pole of the diode D6 is connected with a second positive electrode of the bidirectional thyristor VS via a resistor R14. The surge protection-based flickering-prevention table lamp control system has a reminding function, a lamp can be automatically turned off after a certain time when a person reads with the table lamp, so that the person is reminded of needing a rest, and eyes are protected; and meanwhile, the table lamp control system can give outweak light at night, so that the person is prompted of the position of the table lamp, and the person is convenient to use the table lamp. The table lamp control system has a surge protection functionand can be used for suppressing a surge voltage, so that the table lamp control system is prevented from being damaged by the surge voltage.

Description

technical field [0001] The invention relates to a control system, in particular to an anti-flicker desk lamp control system based on surge protection. Background technique [0002] At present, the desk lamp has become an indispensable lighting tool in people's life. The desk lamp is usually controlled by a control system. However, the traditional control system is not stable in operation, which may easily cause the desk lamp to flicker. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the current desk lamp does not have a reminder function, and provide a surge protection-based anti-flicker desk lamp control system. [0004] The object of the present invention is achieved through the following technical solutions: a kind of anti-flicker desk lamp control system based on surge protection, mainly consists of a time base chip U, a bidirectional thyristor VS, a voltage frequency processing circuit, a P pole is grounded, and ...
