LED street lamp energy-saving illuminating system and method

Abstract

The invention discloses an LED street lamp energy-saving illuminating system and method. The system includes an embedded processing unit which is connected with an LED module, an image acquisition module, a brightness adjustment module, a brightness detection module, a wireless transmission module and a solar cell module separately; the image acquisition module is back to a driving direction and is used for acquiring pedestrian and vehicle image information and transmitting data to the embedded processing unit; and the embedded processing unit receives brightness information of the brightnessadjustment module and controls a street lamp switch and brightness according to the acquired pedestrian and vehicle image information. Illuminating resource waste is reduced and traffic and security administration are assisted, and intelligent control of street lamps is realized.

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 the scale of cities, great achievements have been made in the lighting construction of various cities. With continuous development and continuous consumption of resources, energy conservation has become an important topic 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 lamps consumes more than 20 million kilowatt-hours of electricity per year on street lighting alone. Traditional road lighting technology has been playing 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 ...

AI Technical Summary

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
