What are the configurations of LED solar street lights, and what are they used for?

LED solar street light is a type of street light that uses solar energy to generate electricity and uses LED bulbs as a light source. It has the advantages of energy saving and environmental protection, long life, high brightness, etc., and is widely used in urban roads, rural roads, parks, squares and other places. Here are a few common configurations of LED solar street lights and their uses::

1.Solar panels: Solar panels are the core components of LED solar street lights, which are used to convert solar energy into electricity for street lights. Solar panels are usually made of polycrystalline silicon or monocrystalline silicon materials, which have the characteristics of efficient conversion and durability.

2.LED bulb: LED bulb is the light source of LED solar street light, which has the characteristics of high brightness, low energy consumption and long life.

The color of LED bulbs can be selected according to your needs, and the common ones are white light, yellow light, etc. The power and number of LED bulbs can be configured according to the needs of the street lights to achieve the proper lighting effect.

3.Battery: A battery is used to store the electricity emitted by solar panels to supply LED bulbs at night or on cloudy days. The battery usually uses lead-acid battery or lithium-ion battery, which has high power storage capacity and cycle life.

4.Controller: The controller is used to control the working mode of LED solar street lights, including switch, brightness adjustment, light control and other functions.

The controller can automatically adjust the brightness of the LED bulb according to the ambient light intensity to achieve energy saving. At the same time, the controller can also monitor the battery level, and automatically switch to energy-saving mode when the power is low, extending the use time of the street lights.

5.Brackets and light poles: Brackets and light poles are used to install LED solar street lights so that they can be firmly fixed on the ground. Brackets and light poles are usually made of corrosion-resistant, weather-resistant materials to ensure the stability and durability of street lights.

6.Light Control Sensor: The light control sensor is used to sense the ambient light intensity and automatically adjust the brightness of the LED bulb according to the change in light intensity. The light-controlled sensor can be adjusted according to different needs to achieve a balance between energy saving and lighting effects.

In a word, the configuration of LED solar street lights includes solar panels, LED bulbs, batteries, controllers, brackets and light poles, light control sensors, etc. The function of these configurations is to convert solar energy into electrical energy for LED bulbs, and realize the switching, brightness adjustment and energy-saving control of the bulbs through the controller, so as to achieve energy-saving and environmentally friendly, long-life, high-brightness lighting effects.

Solar street lights are composed of the following parts: solar panels, batteries, solar street light controllers, LED light sources (there are also other light sources that are too cost-effective), light poles, and some accessories. Friends in need can consult below**, our company specializes in the production of solar LED street lights, which are widely used in urban and rural areas in the northern region.

Solar LED street lights are mainly composed of solar cell module parts (including brackets), LED lamp heads, and control boxes.

It is composed of several parts: controller, battery) and light pole; The solar panel has a luminous efficiency of 127Wp m2, which is highly efficient, which is very beneficial to the wind-resistant design of the system. The LED lamp head light source adopts a single high-power LED (30W 100W) as the light source, using a unique multi-chip integrated single-module light source design, and using imported high-brightness chips.

1. Time control function setting. According to the daily lighting time designed in the design scheme, set the time control point according to the instructions of the controller manual, and the lighting time per night should not be higher than the design value, equal to or less than the design value. 2. Light control function collapses old cherry blossom simulation.

If it is in the daytime, after wiring, you can completely block the light side of the solar cell array with opaque (or remove the wiring of the battery pack containing sensitive parts on the controller), and see whether the lamp can be automatically lit after the corresponding cluster time according to the delay time mentioned in the controller manual (generally 5min). If it can be lit, it means that the light switch function is normal, and if it cannot be lit, it means that the light switch function is invalid, and the controller settings need to be checked again.

The choice of the controller is often a problem ignored by the engineering company, the quality of the controller is uneven, the 12V 10A controller market is 100-200 yuan, although it is the smallest part of the value of the entire street lamp system, but it is a very important link. The quality of the controller directly affects the component life of the solar street light system and the procurement cost of the whole system.

One: should choose a controller with low power consumption, the controller works 24 hours a day, if its own power consumption is large, it will consume part of the power, it is best to choose a controller with a power consumption of less than 1 milliampere (ma).

2: To choose a controller with high charging efficiency, the controller with MCT charging mode can automatically track the maximum current of the battery board, especially in winter or insufficient light period, MCT charging mode is about 20 times more efficient than others.

Three: should choose a controller with two-way power regulation, the controller with power regulation has been widely promoted, in the night pedestrian sparse period can automatically turn off one or two lights to save electricity, but also for LED lights power adjustment. In addition to the above power-saving functions, we should also pay attention to the protection function of the controller for the battery and other components, such as the controller with trickle charging mode can protect the battery well, increase the life of the battery, and set the controller under-voltage protection value, try to adjust the under-voltage protection value to prevent the battery from over-discharge.

Solar panels are the core part of solar street lights, and they are also the part with the highest application value in solar street lights. Its function is to convert the sun's radiant energy into electricity, or send it to a storage battery for storage. Among most solar cells, there are three types of solar cells: monocrystalline silicon solar cells, polycrystalline silicon solar cells, and amorphous silicon solar cells.

In the eastern and western regions with sufficient sunlight and good sunshine, it is better to use polycrystalline silicon solar cells, because the production process of polycrystalline silicon solar cells is relatively simple, and ** is lower than monocrystalline silicon solar cells. In the southern region, where there are more rainy days and less sunshine, it is better to use monocrystalline silicon solar cells, because the performance parameters of monocrystalline silicon solar cells are relatively stable. Amorphous silicon solar cells are better in the case of insufficient sunlight outdoors, because amorphous silicon solar cells have lower requirements for sunlight conditions.

In addition, the development of the second generation of solar cells is about to make breakthroughs, and its core component is a bondable thin film, that is, thin-film solar cell materials.

With the increasing shortage of traditional energy sources, the application of solar energy will become more and more extensive, especially in the field of solar power generation, which has developed into a mature sunrise industry in just a few years.

At present, one of the most important links restricting the application of solar power generation is **, taking a two-way solar street lamp as an example, the load of the two roads is 60 watts, (with the effective light day in the middle and lower reaches of the Yangtze River, discharging 7 hours per night, and increasing the battery panel 20 reservations) The battery panel needs to be about 160W, calculated at 30 yuan per watt, the cost of the battery panel is 4800 yuan, plus the battery pack cost of about 180Ah is also about 1800, The one-time input cost of the whole street lamp is much higher than that of the city circuit lamp, which causes the main bottleneck in the application field of solar street lamp.

The service life of the battery should also be considered in the application of the entire street lamp system, the general battery warranty is three or five years, but the general battery will appear in one year, or even half a year later, the charging is not satisfied, and some of the actual charging rate may drop to about 50, which will inevitably affect the normal lighting at night during the continuous rainy days, so it is particularly important to choose a better battery.

Some engineers often choose LED lamps as the lighting of solar street lights, but the quality of LED lamps is uneven, and the LED with serious light decay may attenuate 50 illuminance in half a year. Therefore, be sure to choose LED lamps with slow light decay, or choose induction lamps, low-pressure sodium lamps, etc.

In the practical application of many solar street lights, the solar street lights in many places can not meet the normal lighting needs, especially in rainy days are more prominent, in addition to the use of poor quality related components, another main reason is to blindly reduce the cost of components, not according to the needs of the design configuration, reduce the use of panels and batteries standards, so the street lights can not provide lighting in rainy days.

Solar street lighting is mainly set up for the controller.

Now the controllers are all intelligent controllers, and some of them have buttons directly on the controller, and you can set the parameters by pressing them according to the manual.

Some of them are set up on a computer or with a remote control.

The setting parameters are all the same, mainly including:

1. Light control voltage: generally about 5V, that is, the lights will automatically turn on when it is dark, and the lights will be turned off when the lights are braked at dawn. The higher it is, the sooner the light will be turned on or the later it will be turned off.

2. Under-voltage protection voltage: generally 12V battery voltage is set. That is, when the battery voltage is lower than this number, the light should be turned off.

3. Overvoltage protection voltage: This value does not need to be set normally, and it has been set inside the controller. If you need to set it, the 12V battery is usually set.

This is set according to the actual lighting time, for example, at night the lighting starts for 3 hours, the brightness is 100%, then the brightness is 50% for 3 hours, and then the lights can be turned off for 2-3 hours, and then the lights are on for 1-2 hours, and the brightness is set by yourself.

This is mainly done to extend the lighting time.

Yangzhou Guozhen Lighting Appliance will answer for you: first.

1. Luminous efficiency.

The luminous efficiency of LED is one of the higher light sources on the market, and it only needs to consume very little electricity, and it is also an energy-saving product on the market, so it is also very consistent with our solar energy.

Clause. Second, the service life is long.

That is, its service life is very long, and the adaptability to the operating temperature of the life is also very strong, which can meet the use of our street lamps in the outdoor environment. And it can also have a better safety and reliability, so often when used outdoors, to ensure a better safety effect, especially street lights and other public facilities, is very important.

Clause. 3. Low energy consumption.

Under the same brightness, the electrical energy consumed by LED light sources is often one-ninth of that of incandescent lamps, and it is also one-third of other light sources, but it can exceed a lot in terms of life. Therefore, it has very obvious advantages in practical application, and the application in solar street lamps is naturally common.

There are many factors to consider when configuring solar street lights, the most important of which is the local climate. For example, in the southwest region, there is more rain and less sunshine, so there are photovoltaic panels.

The configuration of the battery should be larger, and vice versa is true in places with plenty of sunshine.

The second thing to consider is the duration of the lights, which is also a factor that determines the photovoltaic panels and batteries. There is also a need to consider the height of the light pole to choose the right light source, the light pole is high, the light source is small, then you know that it will not appear bright. General configuration in general.

6m light pole. Accumulator 80ah

Photovoltaic panels 90W

Sufa lighting answers that if you want a high-configuration and trouble-free solar street lamp, you need to understand the light coefficient of this area, the width of the road surface and the height of the street lamp, etc., the height of the lamp pole and the brightness of the lamp head should be suitable, the power of each time period and the general rainy days in this area should be suitable for the capacity of the battery, and the power of the solar panel should be suitable for the storage capacity of the maintenance-free battery.

1.The size of the PV modules used in solar street lights depends on the power of the light source and the sunshine conditions of the place where they are used.

2.The total amount of solar energy in an area depends mainly on the latitude and longitude and the height of the sea waves.

3.The calculation of the battery is mainly determined according to the time of day of the rainy day.

Solar street lights are mainly composed of the following parts:

street light source; solar photovoltaic modules; Accumulator; solar controllers; Street lamps, light poles and other accessories.
