The role of led solar street lights

>

Municipal road lighting is closely related to our manufacturing and daily life. With the acceleration of urbanization in my country, emerald green, high-efficiency, environmental protection, and long-life led solar street lights have gradually entered everyone's production and daily life; the biggest advantage of solar street lighting is that it does not require It can be easily installed on municipal roads, city squares, ecological parks, underground parking lots and expressways for building power lines, digging trenches, and laying cable lines without the need for full-time personnel management methods and manipulations. Compared with traditional lighting equipment, LED light-emitting tube LED lighting lamps have small size, light weight, good specificity, and can withstand a variety of extreme climatic conditions. At the same level, there are incomparable advantages of other light sources, coupled with the environmental protection, energy saving, high efficiency and simple installation and maintenance of solar lighting fixtures, which will eventually push everyone into a new era of energy-saving lighting. The led solar street light is composed of solar panels, batteries, high-brightness lighting fixtures, control panels and other components. When everything is operating normally, there are very few fitness exercise components, and there is no noise at all. The control loop in the LED solar street light control panel is basically the same as that of the general street light control panel. It is all to better perform the actual operation of flashing the lights when it is dark and turning off the lights at dawn. There are many differences. A method for managing the charging and discharging of batteries in a battery. There are three common street light control panels in the world: independent light control switch, digital clock control panel and Jingwei type control panel. Their principles are different, and they all have advantages and disadvantages.

1.1 Independent Optical Switch

The independent light control switch adopts a light-sensing camera. When the light source is dark and the light source is poor, the street lights are automatically turned on; when the fish belly is exposed in the morning, the street lights are automatically turned off, which can achieve the effect of the automatic control system. The early light-controlled switches used discrete semiconductor material electronic devices, the power supply circuit was complicated, and the equipment failure rate was high; with the development trend of semiconductor technology, time-based integrated circuit chips appeared, which made the light-controlled switching power supply circuit simple and light. The sensor camera is an important electronic device of the light control switch.

1.2 Digital Clock Manipulator

The control board should be set with a timer switch in advance, so that the street lights flash on time and turn off the lights on time, so as to achieve the purpose of automatic control system and energy saving. Its advantage is that the pre-set power switch is affected by the external light source. Except for its own common faults, it is not easy to cause wrong operation. Timing switches, for example: it gets dark earlier in winter and spring, and it gets late; in autumn and winter, it gets early and it gets dark later; there are fewer cars and passersby on the road after midnight, so reduce the total number of flashing lights as much as possible, and turn on the lights before dawn. They illuminate for road safety and power saving. The timer switch in the digital clock control board is divided into two types: mechanical equipment clock type and electronic device clock type: the former one is dominated by quartz clocks, and the error of mechanical watches is accurate, but because the plastic gears used in the watch core can not be used at high temperatures. deformation, and then cause the mechanical watch error to be prohibited or even shut down; the latter type of timer switch is commonly used in electronic clock power supply circuits such as LR6818, LM8650 and other field effect transistors as the management center. The FET integrated with the display screen can set six groups of power switch points and has the function of worship. Many LED solar street light manufacturers are competing to produce this product, and most of them are now used in street light control panels.
