Abstract

The invention discloses a high-stable control system for a table lamp capable of preventing flickering. The system is characterized in that the system is mainly composed of a time base chip U, a two-way thyristor VS, a diode D4 and the like, wherein a P pole of the diode D4 is connected to the ground, and an N pole of the diode D4 is connected with a second positive pole of the two-way thyristor VS through a resistor R11. The high-stable control system has the reminding function, when people adopt the table lamp to read books, the table lamp can be automatically switched off after a period, accordingly, people are reminded of rest, and eyes are protected; meanwhile, the system can give off faint light at night, accordingly, people can be reminded of the position of the table lamp, and people use the table lamp conveniently. According to the high-stable control system, ripple voltage can be well filtered, and accordingly the system works more stably.

Description

technical field [0001] The invention relates to a control system, in particular to a highly stable desk lamp control system capable of preventing flickering. 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 control system of the desk lamp is not stable and easily cause the desk lamp to flicker, and to provide a highly stable desk lamp control system that can prevent flickering. [0004] The purpose of the present invention is achieved through the following technical solutions: a highly stable desk lamp control system that can prevent flickering, mainly consists of a time base chip U, a bidirectional thyristor VS, a voltage ...
