High quality solar street light
Solar energy is an inexhaustible, clean, non-polluting and renewable green energy source. The use of solar power, unparalleled cleanliness, a high degree of security, the relative breadth and sufficiency of energy, long life and maintenance-free and other conventional energy does not have the advantages of photovoltaic energy is considered the most important new energy in the twenty-first century.
Solar street lights do not need to lay cables, AC power supply, do not produce electricity; DC power supply, control; with good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving, environmental protection, economic and practical advantages.
It can be widely used in urban main and secondary roads, neighborhoods, factories, tourist attractions, parking lots and other places. Product components lamp pole structure: steel lamp pole and bracket, surface spraying treatment, battery panel connection using special anti-theft stainless steel screw system composition.
Solar street light system can guarantee more than 15 days of normal work in rainy weather! Its system composition is composed of LED light source (including drive), solar panels, battery (including battery holding tank), solar street light controller, street light pole (including foundation) and auxiliary materials wire and other parts.
Solar cell components generally use monocrystalline silicon or polycrystalline silicon solar cell components; LED lamp head generally use high-power LED light source; controller is generally placed in the light pole, with light control, time control, overcharge and overdischarge protection and reverse connection protection.
More advanced controller with four seasons to adjust the light time function, half-power function, intelligent charge and discharge function; battery is generally placed in the ground or will have a special The battery insulation box, can be used valve-regulated lead-acid batteries, colloidal batteries, iron and aluminum batteries or lithium batteries, etc. Solar lamps and lanterns work fully automatically and do not require trenching and wiring, but the poles need to be installed on pre-buried parts (concrete base).
LED light source
- High luminous efficiency, low power consumption, long service life and low working temperature.
- High safety and reliability.
- Fast response speed, small unit size, green and environmental protection.
- The same brightness, power consumption is one tenth of the incandescent lamp, one third of the fluorescent lamp, but the life is 50 times the incandescent lamp, 20 times the fluorescent lamp, is the fourth generation of lighting products following the incandescent lamp, fluorescent lamps, gas discharge lamps.
- The introduction of a single high-power ultra-bright LED is the application area of LED across to the high-efficiency lighting source market has become possible, will be one of the greatest inventions of mankind after Edison invented the incandescent lamp.
Battery component holder
1） Tilt angle design
In order to make the solar cell module receive as much solar radiation as possible in a year, we have to choose an optimal tilt angle for the solar cell module.
The discussion on the issue of the best inclination angle for solar modules is used in different areas and is based on different regions.
2) Wind-resistant design
In the solar street light system, the structure of a need to pay great attention to the issue of wind resistance design. Wind resistance design is mainly divided into two major pieces, one is the wind resistance design of the battery module bracket, and the other is the wind resistance design of the light pole.
The main role of solar charge and discharge controller is to protect the battery. The basic function must have overcharge protection, over discharge protection, light control, time control, anti-reverse connection, charge trickle protection, under voltage protection, waterproof protection, etc.
Solar street light working principle description: solar street light in the daytime under the control of intelligent controller, solar panels after the sun’s irradiation, absorb solar light and converted into electricity, solar cell components to the battery pack charging during the day, the battery pack at night to provide power to the LED light source power supply to achieve the lighting function.
The DC controller can ensure that the battery pack is not damaged by overcharging or over discharging, and it also has the functions of light control, time control, temperature compensation and lightning protection, reverse polarity protection, etc.
- Easy to install: Outdoor solar street light installation, no auxiliary complex lines, only a cement base, make a battery pit, with galvanized bolts that can be fixed. Do not need to consume a lot of human, material and financial resources consumption, simple installation, no need to erect lines or “open” digging construction, and there are no power outage or power restrictions concerns.
- Less investment capital: solar street light is an investment, with long-term benefits, due to the line is simple, has no maintenance costs, and no expensive electricity. 6-7 years to recover costs, 3-4 years to save more than 1 million in electricity and maintenance costs. It can save the high electricity cost of utility street lights, complicated lines, and the need for long-term uninterrupted maintenance of the lines. Especially in the case of unstable voltage, sodium lamp is inevitable, and with the extension of the years, the line aging, and maintenance costs are increasing year after year.
- Good safety performance: Outdoor solar street lights are an ideal product for ecological communities and road departments because it uses 12-24V low voltage, stable voltage, reliable operation, and no safety hazards. There are no accidents such as electric shock and fire. Municipal electric street light safety hazards, people’s living environment in the changing circumstances, road renovation, construction of landscape projects, the power supply not being normal, water and gas pipeline cross construction, and many other aspects bring many hidden dangers.
- Energy saving and environmental protection: solar photoelectric conversion to provide electrical energy, inexhaustible. No pollution, no noise, no radiation. Solar street lights can add new selling points for the development and promotion of noble ecological communities; they can sustainably reduce property management costs and reduce the cost of the owner’s public share. In summary, the inherent characteristics of solar lighting such as safety without hidden dangers, energy saving without consumption, green, easy installation, automatic control, and maintenance-free will bring obvious advantages for the sales of properties and municipal projects directly.
- Long life: the life of solar lamps and lanterns is much higher than the life of ordinary electric lamps and lanterns, such as the life of the main components of solar lamps—- solar cell module 25 years; the average life of low-voltage sodium lamp is 18000 hours; the average life of low-voltage high-efficiency trichromatic energy-saving lamps 6000 hours; the average life of super bright LED is more than 50000 hours; the life of solar battery The life span of the battery for solar energy is 2-5 years below 38AH; 3-7 years for 38-150AH. Products with high technological content, control systems, and accessories are international brands, intelligent design, and reliable quality.
