Abstract

The invention discloses a low-interference pulse regulation-type photoelectric control lighting and dimming system. The low-interference pulse regulation-type photoelectric control lighting and dimming system is characterized by mainly comprising a signal transmission circuit, a pulse regulation circuit, a unidirectional thyristor D5, a field effect tube MOS, a triode VT2, a triode VT3, a capacitor C7 and the like, wherein the pulse regulation circuit is connected with the signal transmission circuit; and a positive electrode of the capacitor C7 is connected with a drain of the field effect tube MOS and a negative electrode is connected with a collector of the triode VT2. By the low-interference pulse regulation-type photoelectric control lighting and dimming system, amplifying treatment can be carried out on pulse signal voltage, so that the response speed of the low-interference pulse regulation-type photoelectric control lighting and dimming system is improved, and the sensitivity of the photoelectric control lighting and dimming system is higher. The low-interference pulse regulation-type photoelectric control lighting and dimming system has good dimming linearity, and is very uniform and fine in brightness in the dimming process; light flickering and shaking are reduced; and the lighting effect is improved.

Description

technical field [0001] The invention relates to the field of photoelectric control, in particular to a low-interference pulse regulation type photoelectric control lighting dimming system. Background technique [0002] With the development of electronic technology, the control method of lighting equipment is also constantly improving. At present, photoelectric control system is usually used to control lighting equipment. Compared with manual switch control, photoelectric control method is more suitable for frail elderly and disabled Brings great convenience. However, the sensitivity of the existing photoelectric control system is not high and cannot meet people's requirements. Contents of the invention [0003] The object of the present invention is to solve the defect of low sensitivity of the existing photoelectric control system, and provide a low-interference pulse regulation photoelectric control lighting dimming system. [0004] The purpose of the present invention...
