The invention discloses an entrance guard illumination driving system based on a driving protection circuit. The entrance guard illumination driving system includes a chip judgment circuit consisting of a chip U1 and a resistor R3 serially connected between a CK pin and a VDD pin, wherein the model of the chip U1 is TT6061. The entrance guard illumination driving system further comprises a driving input circuit and an input triggering circuit respectively connected with the chip judgment circuit, an illumination triggering circuit connected with the input triggering circuit and the driving protection circuit connected with the illumination triggering circuit. The entrance guard illumination driving system based on the driving protection circuit makes an illumination system more sensitive, improves the response speed, makes people get more timely illumination in the entrance guard using process and further improves a product using effect.
Description
technical field [0001] The invention belongs to the field of building access control lighting, in particular to an access control lighting driving system based on a driving protection circuit. Background technique [0002] The access control is a device used to protect the safety of residents. Users need to pass the access control certification before entering the house. This can better improve the safety of the residents' living, and at the same time, it can also prevent criminals and various social personnel from mixing in. Residential area. In order to improve the use effect of access control, especially when the light is insufficient at night, people often use related lighting devices around the access control, but the use effect of the existing lighting devices is not satisfactory, and its sensitivity is low, which is not conducive to timely Even if the lighting is insufficient, it will lead to misoperation of the occupants, ranging from inability to open the access co...
