Solar street lights are an important part of the urban environment. They provide electricity to lighting and communication systems in the city. It is important to keep them up-to-date and provide clean energy to the people, who need it most.
How to choose a suitable and good solar street light - Blog
1. Firstly you need know detail condition of the road will be installed by solar street light. The basic details including road width, road type .Then you can according these parameters to choose how much watts lights you need refer to below figure 1. This figure is just for your reference. Actually you can send above base information to your supplier ,they can make a road lighting simulation by Dialux tool. By this way, You will also can distinguish your supplier is professional or not. 2. Secondly, Choose a good light source with type â ¢(Bat Wing) lighting distribution curve as figure 2. (Tips:this type is special for roadway.) This figure is from our Vega series all-in-two solar street light. If you want to more details of this product , you can click the web link: If your solar light is not for roadway, such as for walkway,pathway ans side walks, you can choose typeâ ; if for wide walkways, on ramps and entrance roadways, you can choose type â ¡. More type information, you can log into our website:www.jsdsolar.com to down load the PDF files named "LED Distribution Type". A good light distribution type will be with a wider lighting area to realize better lighting effect. 3. Thirdly, after above two steps, you already know how much installation height and how much watts light you will need. Now you can make a calculation for pole to pole space distance according these data. Normally, we recommend the installation space is 23 times of the installation height. Take an example, if installation height is 10m,we recommend space distance is about 30m. 4. Fourthly, after above 3 steps , you already can choose a how much watts lights and how much height installation, how much meters space distance. But you still not know these lights are mostly suitable to your location or not? Because this is a solar street light, so means it has relationship with local weather especially the sunshine.Therefore, you need query the last 5 years annual average sunshine hours, if possible, 10 years is more better. Take an example, if your query data is 4 hours sunshine per day, so the solar panel power is equal to the battery capacity(unit in Wh) divide 4. This is the recommended solar panel power, you can compare it with the supplier solar light technical specification on solar panel item. In addition, you will ask how to calculate the solar light battery capacity. It is related with lamp power, work time, work mode and backup time. Normally the supplier will give you some work mode options by setting a small remote control or mobile app control. Then compare them with your detail requirement to find a best solution.
What is the role of solar street light controllers | Socreat Electronics Technology Limited
The solar street light controller adopts an intelligent power reduction algorithm based on the remaining battery power to ensure that the battery works in the best condition. This will greatly prolong the lifespan of the battery. At the same time, the controller also has high-precision temperature compensation function. The solar street light controller controls the output voltage from the output terminal. Regarding 24V system, if the battery voltage does not reach the 36V, required voltage for normal lighting ON, the controller will raise the output voltage to achieve the lighting requirement. This function must be realized by the solar street light controller. The LED needs constant current or current limiting by technical means to perform normal work. Usually the LED lights are powered by an external drive power for constant current of the LED. A single night can be split into three-stages. Each section lights for several hours, generally 3 hours 3 hours 2 hours configuration, a total of 8 hours. Of course, you can also set it to only light for 6 hours. Road Smart, as solar controller industry-leading team, they have rich experience on intelligent solar street light development.
