Energy-saving lighting system and method for LED street lamp

Abstract

The invention discloses an energy-saving lighting system and method for an LED street lamp, which includes an embedded processing unit connected to an LED module, an image acquisition module, a brightness adjustment module and a brightness detection module respectively; the image acquisition module is opposite to the driving direction , used to collect pedestrian and vehicle image information, and transmit the data to the embedded processing unit; the embedded processing unit receives the brightness information of the brightness adjustment module and controls the street light switch and brightness according to the collected pedestrian and vehicle image information; reduces lighting resources Waste and assist traffic and public security management, realize the intelligent control of street lights.

Description

technical field [0001] The invention relates to the field of LED lamp lighting, in particular to an energy-saving lighting system and method for LED street lamps. Background technique [0002] Since the reform and opening up, with the continuous development of my country's economy and the continuous expansion of urban scale, great achievements have been made in lighting construction in various cities. With continuous development and continuous consumption of resources, energy saving has become an important issue in urban lighting. According to statistics, urban street lights Lighting accounts for about 30% of my country's lighting power consumption. A city with 10,000 street lights consumes more than 20 million kilowatt-hours of electricity every year just for street lighting. Traditional road lighting technologies have played a leading role in road lighting for a long time, such as high pressure sodium lamps (HPS) and some metal halide lamps (MH). However, due to the lack o...

Problems solved by technology

However, due to the lack of directionality of the traditional light source, it is difficult to control the light distribution of the light source, resulting in some problems in traditional street lighting, such as: glare, uneven light intensity distribution, reflection to the sky, light pollution, and waste of light energy, etc.

In recent years, LED lighting technology has developed rapidly. LED has been widely used in urban road lighting due to its advantages of long life, shock resistance, high efficiency, and good control of light sources. However, there are still problems of lighting waste, public security management, and night traffic safety hazards. question
