Power amplifier-based outdoor intelligent lighting system

Abstract

The invention discloses a power amplifier-based outdoor intelligent lighting system. By the power outdoor intelligent lighting system, the problem that a lighting lamp cannot be automatically turned on and turned off according to an application environment to cause energy waste in the prior art is mainly solved. The power amplifier-based outdoor intelligent lighting system comprises an AC contactor, a rectification circuit, a lighting control circuit and an LED lighting lamp, wherein the AC contactor is externally connected with a sine wave alternating current, the rectification circuit and the lighting control circuit are connected with the AC contactor, the LED lighting lamp is connected with the rectification circuit, and a lighting control circuit comprises a two-input four-and gate chip, a power amplifier A1, a first filtering circuit, a photosensitive diode VD1, a power amplifier A2, a second filtering circuit and a photosensitive diode VD2. By the scheme, the power amplifier-based outdoor intelligent lighting system has the advantages of simple structure, low cost, running stability, energy saving, detection accuracy and the like, and has high practical value and promotion value in the technical field of lighting.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an outdoor intelligent lighting system based on a power amplifier. Background technique [0002] With the continuous development of lighting technology, intelligent lighting technology is becoming more and more mature. LED lighting fixtures have the characteristics of strong brightness, low power consumption, and long service life, providing users with maintenance-free lighting solutions. At present, most outdoor lighting equipment has gradually adopted maintenance-free LED lighting fixtures, which mainly include LED lights, controllers and mounting brackets. In order to realize automatic opening and closing of lighting fixtures, timers are often used to set the turn-on time. and closing time. But, the time of timer setting is fixed, if want to change the time of opening or closing lighting fixture, also must revise regularly. In rainy or cloudy weather with poor visibility, i...
