Solar street lights are powered by crystalline silicon solar cells, maintenance-free valve-controlled sealed batteries (colloid batteries) to store electricity, LED lamps as light sources, and controlled by intelligent charge and discharge controllers. They are energy-saving street lights that replace traditional public power lighting. Solar street lights do not require laying cables, AC power supply, or electricity bills; solar street lights are worry-free and can save a lot of manpower and energy. Solar street lights use DC power supply and photosensitive control; they have the advantages of good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, and economical and practical. They can be widely used in urban main and secondary roads, communities, factories, tourist attractions, parking lots and other places. 2. Product component lamp pole structure 1. Steel lamp pole and bracket, surface spraying treatment, and patented anti-theft screws are used for battery panel connection.
The solar street light system can ensure normal operation for more than 8-15 days in rainy weather! Its system consists of (including bracket), LED lamp head, solar lamp controller, battery (including battery insulation box) and lamp pole.
Solar cell modules generally use monocrystalline silicon or polycrystalline silicon solar cell modules; LED lamp heads generally use high-power LED light sources; controllers are generally placed inside the lamp poles, with light control, time control, overcharge and over-discharge protection, and reverse connection protection. More advanced controllers have functions such as adjusting the lighting time in all seasons, half-power function, and intelligent charging and discharging functions; batteries are generally placed underground or have special battery insulation boxes, and can use valve-regulated lead-acid batteries, gel batteries, iron-aluminum batteries, or lithium batteries. Solar lamps work fully automatically and do not require trenching and wiring, but the lamp poles need to be installed on embedded parts (concrete bases).
LED light source
⒈High luminous efficiency, low power consumption, long service life, and low operating temperature.
2. Strong safety and reliability.
⒊Fast response speed, small unit size, and green environmental protection.
⒋ Under the same brightness, the power consumption is one-tenth of incandescent lamps and one-third of fluorescent lamps, while the life span is 50 times that of incandescent lamps and 20 times that of fluorescent lamps. It is the fourth generation of lighting products after incandescent lamps, fluorescent lamps, and gas discharge lamps.
⒌ The advent of single high-power LED is a good product that has crossed the LED application field to high-efficiency lighting sources for market lighting. It will be one of the greatest inventions of mankind after Edison invented the incandescent lamp.
Battery component bracket
1) Inclination design
In order to allow the solar cell components to receive solar radiation throughout the year, the best inclination angle is selected.
There are many discussions on the optimal inclination angle of solar cell components in some academic journals. The area where the street lamp is used this time is Xinyang, Henan Province, and the inclination angle of the solar cell component bracket is selected to be 35°.
2) Wind resistance design
In the solar street lamp system, a structural issue that needs to be paid great attention to is wind resistance design. Wind resistance design is mainly divided into two parts, one is the wind resistance design of the battery component bracket, and the other is the wind resistance design of the lamp pole.
Controller
The main function of the solar charge and discharge controller is to protect the battery. The basic functions must include overcharge protection, over-discharge protection, light control, time control, anti-reverse connection, charging trickle protection, undervoltage protection, waterproof protection, etc.
Working principle
Description of the working principle of solar street lights: During the day, under the control of the intelligent controller, the solar panel absorbs solar light and converts it into electrical energy after being irradiated by sunlight. During the day, the solar cell module charges the battery pack, and at night the battery pack provides power to the LED light source to realize the lighting function. The DC controller can ensure that the battery pack is not damaged due to overcharge or over-discharge, and it also has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection.
