Product Description:

 Working Principle of solar street light
The solar energy is converted into electricity which is stored in the battery through the solar
panel during the day time. The solar panel voltage will decrease gradually with the reduction of
solar radiation. When the solar panel voltage is lower than stipulated voltage, the battery will
supply electricity to load automatically through the controller; When the dawn comes, the solar
panel voltage increase gradually. After the voltage is larger than stipulated voltage, the
controller will cut off the electricity from battery and switch the energy supply to solar panel.

advance of Solar Led Street Light:


LED is the fourth generation of light source after incandescent lamp, fluorescent lamp and HID. Compared with
traditional light source, LED light source has following advantages
High lighting efficiency.
Incandescent lamp: 12-24LM/W. Fluorescent lamp: 50-70LM/W. Sodium lamp: 90-140LM/W. LED lamp:
Low power consumption.
The power consumption of LED lamp is 40%-60% of traditional lamps.
Long life span.
Life service life of LED lamp is 5 to 10 years.
Safe and reliable.
Low heat, no thermal radiation, tangible, cold light, free from glare, no toxic element like Mercury and Sodium
Shock proof, recyclable, no pollution, less lubricious attractive to insects, no bad impact on ecological

Q:What are the parts of the solar lamp
Regardless of the size of the solar fixture, a well-behaved charge-discharge controller is essential. In order to extend the battery life, it must be its charge and discharge conditions to be limited to prevent the battery overcharge and deep charge. In the larger temperature difference, the qualified controller should also have the temperature compensation function. At the same time solar controller should have both street lamp control function, with light control, time control function, and should have a night automatically cut off the load function, to facilitate rainy days to extend the street lamp working hours.
Q:What is the meaning of the solar controller battery indicator light
On the other hand, the opposite is full. The general voltage is greater than 12V
Q:Can a solar-charged watch be filled with a fluorescent lamp?
In the incandescent lamp, the output current will be much better, the sun the best.
Q:What are the advantages of solar led street light?
Dispersion: reach the Earth's surface of the total amount of solar radiation despite the large, but the energy density is very low. On average, near the Tropic of Cancer, in the case of sunny weather in summer, the irradiance of solar radiation at noon is the largest, and the average solar energy received in the area of ​​1 square meter perpendicular to the sun is about 1,000W. Year and night average, only about 200W.
Q:What is good for solar lights?
Under normal circumstances is south by west point, because it can get more sufficient sunshine, of course, also has a relationship with the angle, so according to the specific installation location to configure the.
Q:What are the problems of LED solar lights such as high damage rate and low brightness
 Even if 10000 yuan, the difference is the middle of the $8000, and this can be given to the light of the number of points for 8000 minutes? You can count it, personally feel that solar energy is not practical, can only stay in the water heater industry,
Q:The development trend of solar lights
For the market, accelerate the development of the solar cell industry will be promising.
Q:How long can a solar street light be used?
Solar street lamp life is also necessary maintenance, in the early installation, we must strictly in accordance with the construction standards to do, in the configuration as much as possible reasonable configuration, increase the capacity of the battery, thereby extending the life of solar lights.
Q:How to charge the solar lights
Solar panels open circuit voltage of about 4.5V, charge and discharge controller to detect the voltage after the action, the battery discharge to the lamp.
Q:How to determine the power of solar panels solar panels that the number of w
The power of the solar street light depends on the width of the road and the surrounding environment, depending on the width of the road, the line distance depends on the power of the light source and the secondary light distribution of the lamp. With the growing shortage of traditional energy, solar energy applications will be more and more widely, especially in the field of solar power in a few years time has developed industry.
