Advantages of solar LED street lights

Solar LED street lights are closely related to everyone's life, along with the acceleration of the urbanization process in China, green, high efficiency, environmental protection, long-life led solar street lights have slowly entered everyone's production and daily life; Then the characteristics of LED street lights let's take a look.
First, the advantages of solar LED street lights
1, the biggest advantage of solar LED street lighting is that it does not need to build power lines or dig trenches, pave cable lines, without full-time personnel management methods and manipulation, and can be easily installed in municipal roads, city squares, ecological parks, underground parking lots and highways and other sites.
2, compared with traditional lighting equipment, led light tube LED lighting lamp source its small size, light weight, good specificity, can withstand a variety of extreme weather conditions, in the functional loss, application life and environmental protection and other levels of other lamp source can not be compared advantages!
3, coupled with the environmental protection, energy saving and high efficiency of solar lighting and installation, maintenance is simple, will eventually promote everyone into a new era of energy-saving lighting.
4, led solar street lights by solar panels, batteries, high brightness lighting, control panel and other components, all normal operation when the fitness components are very few, the foundation is no noise. The control loop in the led solar street lamp control panel, its function is basically the same as that of the general street lamp control panel, all in order to better carry out the actual operation of flashing lights in the dark and turning off lights in the morning, the difference is that there is more than one management method of battery charging and charging and discharging. The common street lamp control board in the world has three kinds of independent light control switch, digital clock control board and Wei type control board, their principle is not the same, all have advantages and disadvantages, is simply described below.
Two, solar LED street light control switch
The independent light control switch uses the light sensor camera, when the black light source is poor, the street lamp is automatically turned on; When the light is exposed, the street light is automatically turned off, which can achieve the effect of automatic control system. The early light-controlled switch used discrete semiconductor material electronic devices, the power circuit is complicated, and the equipment failure rate is high; With the development trend of semiconductor technology, the emergence of time-based integrated circuit chips, so that the optical switch power circuit is simple, and the optical sensor camera is an important electronic device of the optical switch.
Third, LED street lamp digital clock operator
The control board should set the timing switch in advance to make the street light flash on time and turn off the light on time, so as to achieve the goal of automatic control system and energy saving.
Its advantage is that the power switch set in advance is affected by the external light source, in addition to their own common faults, not easy to cause wrong operation, the defect is not according to the seasonal change and unique weather conditions fully automatic conversion timing switch, must set up full-time personnel to adjust the timing switch, such as: winter and spring dark earlier, dawn is later; Autumn and winter dawn is early, dark is late; Late at night, there are fewer cars and passers-by on the back road, so reduce the total number of flashing lights as much as possible, and illuminate them before dawn to facilitate road traffic safety and save electricity.
The timer switch in the digital clock control board is divided into two types of mechanical equipment clock type and electronic device clock type: the first one is dominated by quartz clock, the mechanical watch error is accurate, but because the plastic gear applied in the watch core can deform at high temperature, resulting in the mechanical watch error prohibition and even shutdown; The latter kind of timer switch is common LR6818, LM8650 and other field effect tubes for the electronic clock power circuit of the management center.
In recent years, there has also been a field effect tube that integrates the electronic clock circuit board with the led liquid crystal display screen, which can set six groups of power switch points, and has a worship function, many LED solar street lamp manufacturers compete to produce the product, most of which are now used in the street lamp control panel.
