FAQ

 

1.How is the effect of the PIR motion sensor?

The light will be in the energy saving mode when it is dark automatically, light will be off when it is dawn. With this characteristic, the light can be used as signal light, indicator light and continuous light.

 

2.What to do with the continuous rainy days?

Although solar light is charged by the sun, our product can work when the battery has electric power storage. We have considered the problem and many new products increase battery capacity, which can store enough power when the sunshine inadequate in case if continuous rainy days. The battery can support about 3 nights after fully charged. You don’t need to worry about the safety for there is overcharge protection for the core circuit board.

 

3.What to do with the rainy day?

Solar light is an outdoor lamp with the waterproof level of IP65. You don’t need to worry about the rainy day.

Q:How to handmade a small solar light
Tubular solar water heaters by the water cycle, is divided into natural circulation and pump, the former simple and cheap, but the requirements of the circular water design is very skillful, or can not cycle, a pool of stagnant water. There is no problem with the pump cycle, but to add electricity consumption, but also spend money to buy a pump, the water requirements on the low.
Q:The working principle of solar lamps
The use of photovoltaic effect of the principle of solar solar panels solar solar panels to receive solar radiation and converted into electrical energy output, through the charge and discharge controller stored in the battery, the night when the illumination gradually reduced to 10lux or so, the solar panel open circuit voltage 4.5V
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: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.
Q:What are the components of the solar street light
Solar street light system consists of LED light source (including drive), solar panels, batteries (including battery incubator), solar street light controller, street lamp poles (including basic) and auxiliary materials and other parts of the composition
Q:What are the problems of LED solar lights such as high damage rate and low brightness
At present there are more solar LED lighting solar street lamp battery, the battery itself is not what the problem is, the most important is the unreasonable allocation of the battery capacity is low, the lighting time constant, but the capacity of the battery, battery life cycles to increase very reduced, life expectancy of 3 years may be the standard battery in 1 years later or 2 years later on a big problem.
Q:What are the features and advantages of solar street lights?
with ordinary light, there are indeed many incomparable advantages. First of all, he is not ditching embedding, the engineering quantity is relatively small, as long as the installation of a cement base, with stainless steel screws fixed on the line. 
Q:What is the working principle of solar lighting?
Left and right, charge and discharge controller to detect this voltage after the action, the battery on the lamp discharge! The simplest said: solar panels will absorb solar energy and converted into electricity after the power reserve battery for night use.
Q:How long can a solar street light be used?
The whole series of solar street lamp life of the short board in the battery, in the purchase of solar street lights when the proposed battery to configure the larger, the development of the battery life is his cycle discharge life, the full discharge is about 400 to 700 times, You battery capacity is enough to discharge only a day, then the battery is easy to damage, but the battery capacity is several times a day discharge, it shows a few days to have a cycle, which greatly increased the battery life , And the capacity of the battery is a few times a day discharge, that is, several consecutive rainy days to ensure.
Q:The development trend of solar lights
But the oil energy shortage, the urgency of coal resources makes the existing power generation is far from meeting the demand for electricity consumption, solar power generation promotion is very urgent, the market potential is enormous.
