Signal amplification type voltage-stabilized source energy-saving passageway illumination system

Abstract

The invention discloses a signal amplification type voltage-stabilized source energy-saving passageway illumination system. The system is characterized by being mainly composed of a central control unit, a power input protection circuit, an illumination driving circuit, a fidelity two-level amplifying circuit, an analog-to-digital conversion chip, an infrared sensor, a light sensor and an illumination lamp, wherein the power input protection circuit, the illumination driving circuit and the fidelity two-level amplifying circuit are connected with the central control unit, the analog-to-digital conversion chip is connected with the fidelity two-level amplifying circuit, the infrared sensor and the light sensor are connected with the analog-to-digital conversion chip, and the illumination lamp is connected with the illumination driving circuit. The fidelity two-level amplifying circuit is arranged, signals output by the infrared sensor and the light sensor are weak, the fidelity two-level amplifying circuit can amplify the signals without distortion, and therefore the sensitivity of the system is improved. The arranged power input protection circuit can ensure that the system has a stable working voltage, and therefore it is avoided that alternating current fluctuation affects normal work of the system.

Description

technical field [0001] The invention relates to the field of energy saving, in particular to an energy-saving lighting system for corridors with a signal amplifying voltage stabilized source. Background technique [0002] At present, the traditional corridor lighting system is controlled by switches. Each corridor light corresponds to a manual switch, which is controlled by pedestrians going up and down the stairs. There is a big defect in this way, that is, pedestrians need to manually turn on the switch; in an open and dark corridor environment, it is not easy for pedestrians entering the building to find the position of the switch for the first time, causing great trouble to pedestrians. At the same time, from the perspective of energy saving, this control method requires pedestrians to turn on and off each corridor light they pass in turn. Frequent operations will easily make people give up the operation of turning off the lights, so that the corridor lights are in a lon...
