The invention discloses a light control device for an advertising board, and relates to the technical field of advertising board equipment manufacturing. The light control device comprises a rectifier and filter module, wherein an output end of the rectifier and filter module is connected with a voltage stabilizing module; the output end of the voltage stabilizing module is connected with a power supply terminal of a control chip; a photoelectric sensor, a first resistor and a second resistor are connected with one another in series to form a first series circuit; a sixth pin and a second pin of the control chip are connected with each other and are connected with a connection line of the photoelectric sensor and the first resistor; a third pin of the control chip is connected with one end of a coil of a relay; a fifth pin of the control chip is connected with the other end of the coil of the relay through a second capacitor; and a normally open contact of the relay is connected with a lamp. The light control device for the advertising board can solve the problem of energy waste due to the fact that the lamp is lighted when not needed in an existing advertising board or advertising lamp box.
Description
technical field [0001] The invention relates to the technical field of billboard equipment manufacturing, in particular to a control device for billboard light control. Background technique [0002] In daily life, the lighting control of billboards and advertising light boxes is often controlled manually. If the staff who manage the billboards and advertising light boxes forget to turn off the power of the billboards and advertising light boxes at a certain period of time, it will cause problems. waste of energy. In today's increasingly prosperous cities, in order to attract customers or promote products, high-power lamps, billboards and advertising light boxes with high energy consumption can be seen everywhere. If the lights are turned on when they are not needed, it will cause a lot of waste. . Contents of the invention [0003] The purpose of the present invention is to provide a lighting control device for billboards, which can solve the problem of energy waste caus...
