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 working principle of solar lighting?
Solar energy into electricity, stored in the battery inside. Battery pack to the lamp (usually LED lights)
Q:What are the advantages of solar led street light?
2, LED solar street light installation is simple and convenient, without the need for ordinary street lights as laying a large number of basic projects such as cable, only need to have a base fixed, all the lines and control parts are placed in the lighthouse, forming a whole. 3, LED solar street light operation and maintenance costs low. The entire system is running automatic control, without human intervention, almost no maintenance costs. Solar street light led the shortcomings
Q:Introduction of solar lights is
LED light source, the general use of LED lamp beads, led lamp beads without filament, mercury and other harmful substances, life of up to 50,000 hours.
Q:What are the features and advantages of solar street lights?
Also, because the solar street lamp free electricity, as long as a you can input, no maintenance cost, generally two three years to recover the investment cost and benefit. Third points, compared with the conventional solar street lights, security is relatively strong, because he is ultra low voltage products, so relatively safe. 
Q:What is good for solar lights?
Can share a lamp holder. Dual power supply is required. The backup power supply mode, the simplest way is the use of relay, usually the work coil it connected to the solar inverter output, midpoint conversion contact load, normally open connected solar inverter output, normally closed connected with the power input, when no inverter output voltage, power relay
Q:Solar lights do not always open but charge every day, the battery will be bad
Open circuit voltage of about 4.5V, charge and discharge controller to detect this voltage after the action, the battery discharge to the lamp.
Q:What are the problems of LED solar lights such as high damage rate and low brightness
The utilization of solar energy itself is not high, only 15%-17%. An ordinary 100WLED street lamp cost even if 2000 yuan, then with the wind and solar complementary system is estimated to be ten thousand yuan. 
Q:The development trend of solar lights
The use of solar photovoltaic power generation is the trend of energy use irreversible.
Q:How to charge the solar lights
During the day, even in cloudy days, this solar generator (solar panel) collects and stores the energy needed.
