Solar street lamps do not need to lay cables, do not need AC power supply, and do not generate electricity charges; Adopt DC power supply and control;
It has the advantages of good stability, long service life, high luminous efficiency, simple installation and maintenance, high safety, energy saving, environmental protection, economy and practicality.
Today, the source code has compiled some basic knowledge of solar street lamp
s to take you to understand the development of solar street lamps.
The difference between solar street lamp and commercial street lamp: introduction of solar street lamp :(1)
No cable, no location restriction, easy installation.
When installing the solar street lamp, it is not necessary to set up a complicated line, but only a cement base and a battery pit within 1 m, which can be fixed with galvanized bolts. (2)High security.
Solar street lamp has relatively stable voltage, reliable operation and no potential safety hazard. It is an ideal product for ecological communities and road administration units. (3)
Solar street lamps do not need to pay electricity bills and are not limited by power outages.
Solar street lamps benefit from one-time investment and long-term benefits. Due to the simple circuit, no maintenance costs and no expensive electricity charges are incurred. (4)
Solar street lamps save energy and have no pollution, which is in line with the development direction of today's society. Characteristics of ordinary street lamps :(1)
It is not very suitable for remote and poor areas and the installation cost is high.
The street lamps of the mains are expensive and the lines are complex, requiring long-term uninterrupted maintenance of the lines.
In the case of special voltage instability, the sodium lamp is inevitable, the aging of the line, the maintenance cost is increasing year by year, and the service life is short. (2)
The power supply method is traditional, requires laying cables, and the installation is complicated. There are complicated operation procedures in the construction of Mains street lamps.
First of all, a large number of civil works such as cables, trenching and pipe laying, pipe threading and backfilling should be supplemented, consuming a lot of manpower, material resources and financial resources.
Finally, debugging is needed. Once problems occur, it will cause great consumption. (3)Low security.
Due to the transformation of construction quality and landscape engineering, the aging of materials, abnormal power supply and conflicts between water and electricity pipelines have brought many potential safety hazards.
Light type of solar street lamp: the shape of light hitting the ground.
The conversion rate of photoelectricity is particularly scarce, so light is particularly precious to solar street lamps. In order to make the best use of every inch of light, the source code has been studying the rational use of light types, reduce the waste of light outside the road.
Finally, a patented lens was developed to distribute the light twice, making the light parallel to the road and improving the utilization rate of the light.
Introduction to street lamp lithium battery: the basic principle of solar energy is that the solar battery converts the solar radiation energy into electric energy during the day and the intelligent controller stores it in the storage battery, at night, the intelligent controller controls the battery to discharge the street lamp, and reasonably allocates the lighting time according to the user's requirements. (1)
The development of new energy vehicles has promoted the development and maturity of lithium battery technology. The development of lithium battery technology has gone through three processes. The first stage is colloidal battery, with a cycle life of 300-500 times, complicated installation and serious pollution. (2)
The second stage, ternary lithium battery, cycle life 300-
500 times, the installation is simple, the life is short, and the safety is not high. (3)
The third stage, lithium iron phosphate battery, cycle life of more than 2000, no pollution, small size, high safety, high temperature performance.
