The large number of LED street lights in the current society has played a decisive role in the progress of lighting engineering. In particular, the energy saving and low carbon aspects of LED street lights have made important contributions to the society. Below we talk about LEDs in daily use. 10 things that Led street lights Manufacturers(CLASSICLEDLIGHT) recommend should be noted.

1. LED street light power must be constant current

The characteristics of the lighting material of the LED street light determine its environmental impact. For example, if the temperature changes, the current of the LED will increase. In addition, the voltage of the LED will increase. If the long-term operation exceeds the rated current, the service life of the LED light bead will be greatly shortened. The constant current of the LED is also the value of the current that ensures its operation when the environmental factors such as temperature and voltage change.

2. LED street light power supply constant current accuracy

The constant current accuracy of some power supplies on the market is poor, the error may reach ±8%, and the constant current error is too large. The general requirement is ±3%. According to the 3% design. The production power supply should be fine-tuned to achieve ±3% error.

3. LED street light power supply operating voltage

The recommended operating voltage of general LED is 3.0-3.5V. After testing, most of the work is at 3.2V, so it is reasonable to calculate according to 3.2V. Total voltage of N light beads in series = 3.2*N

4. What is the most suitable working current for LED street light?

For example, the rated working current of LED is 350 mAh. Some factories use it at the beginning and design 350 mA. In fact, the working heat is very serious at this current. After many comparison tests, it is ideal to design 320 mA. . Minimize heat and turn more electrical energy into visible light.

5. How wide is the series and parallel connection of the LED street light power supply board and the wide voltage?

In order to make the LED street light power supply work in the wide range of input voltage range AC85-265V, the LED series-parallel connection of the light board is very important. Try not to use a wide voltage, can be divided into AC220V, AC110V as much as possible to classify, in order to ensure power supply reliability.

6. Isolated / non-isolated

Generally, if the isolated power supply is made of 15W, it is placed in the LED street light power supply tube. The transformer is large in size and difficult to put in. Mainly depends on the specific structure of the space, the isolation can only be achieved 15W, less than 15W, and the price is very expensive.

7. How can LED street light power supply match the light bead?

In fact, choose the best string parallel connection method, the voltage and current applied to each LED are the same, and the power supply can achieve the best performance. The best way is to first communicate with the power supply manufacturer and tailor it. Or self-produced power.

8. LED street light power efficiency

This parameter is especially important for input power minus output power. The higher the value, the lower the efficiency. This means that a large part of the input power is converted into heat. If it is installed in the light, it will produce a very high temperature. Together with the heat generated by one of our LEDs, it will superimpose to produce a higher temperature.

9. LED street light source cooling

The main factor of the heat dissipation scheme is that the LED street light bead can be used for extended life under the hot condition, and the aluminum alloy is generally used, which is more convenient for heat dissipation. That is, the LED street light power bead is attached to the aluminum substrate, and the external heat dissipation area is maximized.

10. LED street light power supply cooling

The main factor of heat dissipation is that LED street light power beads can greatly extend the life when used under hot conditions. Generally, aluminum alloy heat sinks are used to make heat dissipation easier. That is, the LED street light power bead is attached to the aluminum substrate, and the external heat dissipation area is maximized.

The above ten major issues for us to analyze the attention points of LED street lights in detail, reasonable use will improve the service life of LED street lights, reduce production costs, I believe that anyone will be very interested.

There are still some shortcomings in the use of street light. Among them, there are still some shortcomings in the use of Solar led street light(CLASSICLEDLIGHT), and what problems we need to pay attention to during the use.

There is no uniform standard for street light, and the production enterprises are shoddy and messy, which seriously affects the new energy and service life of solar LED street light. Many newly installed solar LED street lights are damaged after less than one year of use. There are no mandatory requirements for the installation unit and there are a lot of loopholes. Therefore, during the construction process, the workmanship is reduced, and the problem is not solved after the problem occurs so that no one cares about the street light after the damage. One of the problems in the use of street lights is the problem of electricity storage and weather. Solar LED street lights are no exception. For some areas where sunlight is not seen all the year-round, solar LED street lights cannot be used at all. It affects the use of street lights, so these areas can only use traditional electric lighting.

First of all, we need to determine the appropriate light source for the street light power. In the process of road construction, the light source of different power is different in configuration and production. Only by carefully determining the configuration of the street light power meter can the quality of the street light be guaranteed; Need to do the street light system setting, different roads, different needs for lighting time is not the same, the general street lighting time is set at 4-8 hours, to ensure continuous lighting for 3-5 rainy days; Provide good installation and after-sales service, the most important thing to install solar LED street lights is to achieve a good photoelectric conversion of the system to ensure stable operation of the system.

With the acceleration of urbanization, LED street lights have already entered people's field of vision. Today, LED street lights are everywhere in the streets and streets of big cities. It is dotted with the night sky of the city. However, it still does not get the fullest use, because it has its own limitations. In order to ensure that LED street lights can play more roles in our lives, Led street lights Manufacturers(CLASSICLEDLIGHT) should solve these problems in future research, production and promotion.

First: the shape and structure of the luminaire. The shape of traditional street light luminaires is basically the same, which is generally divided into two parts: light source and electric appliance. However, due to the speciality of LED light source and the different light distribution methods, the shape of LED street light luminaires can be described as numerous. Many of them cannot be shaped. To meet operational requirements, even some companies apply indoor streetlights to indoor streetlights.

Second: there is a problem with the connection between the LED light and the light post. At present, almost all LED street lights are fixed by screws, and few hoop bolts are fixed. Thus, there is a great hidden danger to the safe operation of the luminaire.

Third: the issue of replaceability of the luminaire components. LED street light components generally have LED chips, power supplies (drivers), and light housings. The vulnerable parts are mainly power supplies and chips. In general, the LED light chip is an electronic heatsink that cannot be replaced, and the power source (driver) can be replaced. However, many products are not convenient enough to replace the power source (driver), and replacement is time consuming.

As we all know, the life of LED lights can reach 30,000 to 50,000 hours. If the LED chip cannot be replaced, it means that replacing the entire fixture will also result in waste.

The fourth is the life of the power supply (driver). The power supply (driver) is a very critical component of current LED luminaires. But currently the market generally only guarantees the quality of the LED chip, and the life of the power supply (driver) is another matter. The general manufacturer promises to guarantee 2 years is not bad. This is ultimately because the development of LED street lights has encountered a new bottleneck - the quality of the power supply (driver) is not guaranteed, it restricts the development of LED street lights.

The power saving effect of LED street lights. In theory, power saving, but the actual application of LED street lights is not more energy-saving than high-pressure sodium lights. Under the premise of lighting quality standards, the high-efficiency sodium light high-power light (250~400W) has a luminous efficiency of 130~140 1m/W. The high-power LED street light uses 1W LED tube. In theory, its light efficiency is similar to that of high-pressure sodium light. However, considering the three factors of ballast loss, light efficiency and track utilization, considering the current energy efficiency of LED than high-pressure sodium light Lower. The low-power LED street light (≤150W) is 10% more energy efficient than the high-pressure sodium light.

The components of the Solar led street light(CLASSICLEDLIGHT) mainly include batteries, light poles, control inverters, and street light power supplies. What are the functions of these parts? Below we introduce Hengyuan Lighting, about the components of an LED street light. Related introduction.

Solar panels provide energy for solar LED streetlights. Their function is to convert the solar light energy into electrical energy and store it in a battery. It is the most valuable component of solar LED streetlights. The working principle of this part is the solar photon and the radiant heat of the P-N junction hole and electron movement in the solar cell. This is also known as the principle of the photovoltaic effect. The battery is the energy storage of the solar LED street light, and the collected power is supplied to the street light to realize the illumination. Since the input energy of the solar photovoltaic power generation system is extremely unstable, it is generally required to configure the battery system to work. Let us give you an example of these two parts. Let's take a look at the quality standards of each part.

Description of quality standards for various components of solar LED street light:

1. LED luminaire: The thickness of the outer casing determines the quality of the product. The thickness of the aluminum substrate or aluminum plate should reach 1.5mm, the heat dissipation should reach the standard, and the light bead adopts the chips of international brands such as wafer or Puri.

2. Battery: Is it a special battery for energy storage? At present, some unscrupulous companies use the most energy-storing battery to start the power supply, which greatly reduces the life of the street light.

3. Panels: In addition to the use of polycrystalline panels in foggy areas such as Sichuan and Chongqing, monocrystalline panels are recommended in other regions because of the higher conversion rate of single crystals than polycrystals.

4. Light pole: Whether hot-dip galvanizing, hot-dip galvanizing still has galvanized layer in the incision part, cold-galvanized has no galvanized layer in the incision. The upper port diameter is generally 60mm, the bracket diameter is generally 76mm. The light pole has 11 --12 taper ratio.

With the development of the market, led street lights have gradually entered everyone's field of vision. However, if you want led street lights to completely replace other products in the same industry, there are still some problems. What are the specific problems? Here are some questions about the development of Led street lights Manufacturers(CLASSICLEDLIGHT).

One of the problems in the development of led street lights: professional production technology in the industry is an inevitable problem. led street lights have higher luminous efficiency than high-pressure sodium light, which is only due to the technical level. In the market, the led street light industry is currently at an early stage of development.

Furthermore, with the continuous accelerated development of the led era, enterprises gradually realize the importance of product quality and continue to develop towards high quality. The quality of products circulating in the overall market will be improved. The traditional high-pressure sodium light is simply composed of three parts: a bulb, a ballast, and a light shell. The bulb is one of the most easily broken parts, with a life of about 1-2 years. Even if it is broken, it is very convenient to replace, because it is a standardized product and can be replaced by any manufacturer's bulb.

The specifications of led street lights manufacturers are different from one manufacturer to another, and the same manufacturer needs to be found for later replacement or maintenance of products. From an indirect perspective, led street lights have become monopoly-bound products by enterprises. The nonstandard products are the biggest bottleneck in the road of LED street lights. The establishment of standardized standards has become an urgent need for industrial development.。

If the led street light solves the above problems, the high-pressure sodium light street light can fade out of the market. In theory, led street lights should be popularized faster than indoor lighting on roads. However, due to the inertia of road lighting popularization in the market and the above standardization problems, its popularization effect has not been as scheduled.

What is the working principle of led street light? Regarding the use of led street light, what are the precautions that we need to understand? Below, regarding the working principle of led street light and the related instructions, the Led street lights Manufacturers(CLASSICLEDLIGHT) will arrange for you.

First of all, let's understand the working principle of an LED street light. LED street light uses the principle of the photovoltaic effect of solar cells. During the day, solar cells absorb solar photon energy to generate electricity, which is stored in the battery through the controller, when night falls or the brightness around the lights. When the value is low, the controller will perform the discharge operation to turn on the street light to start lighting. Therefore, when buying LED street lights in different regions, we must pay special attention to whether the design ideas and points of the system are in line with the local actual situation. Don't just pursue the low price for saving investment, nor can we blindly pursue high performance and waste resources.

1. The led street light device should be installed on a sunny day. If it is on a rainy day, it will only consume electricity and not charge after lighting. It will not meet the drawing requirements. The LED street light device should not be lit on the day.

2. The viewpoint of the LED street light panel is usually drawn by the manufacturer at a 45-degree angle. This is to ensure a good charge in winter.

3. The connection between the led street light controller. Waterproof controllers should be used as much as possible to ensure that the long-term stability is maintained together, and the user can be prevented from changing the lighting time at will. If a controller that is not waterproof is used, the wiring is bent into a U-shape with the terminal block facing down, which prevents water from dripping from the line into the controller.

Many people know that Solar led street light(CLASSICLEDLIGHT) is attributed to new products and environmental protection products. Both sides of large highways are more convenient for everyone to travel. Originally, the trend of solar LED street light was continuously recognized by everyone, so many units began to test the use of such street lights. The most representative one was during the Olympic Games, when most of our parks adopted such street lights, which included signal lights, landscape lights, lawn lights, etc., adding color to the scenery of the parks and showing the extensive use of high-tech commodities in China.

Many people think that solar LED street light is only a manifestation of scientific and technological strength. Originally, there is no doubt about this sentence. The widespread use of solar LED street light really shows China's strength in using high-tech commodities. But what is more noteworthy is that we use solar LED street light because this power is attributed to clean power. It will not pollute the surrounding environment and will not cause any damage to the living environment of human beings. Therefore, it is widely recognized and implemented by everyone.

Another factor for large-scale units to choose this kind of street light is that it saves a lot of money compared with other street lights. Although it is a high-spirited commodity in terms of installation and commodity cost, it does not need to consume external electric energy in the later period of use. It only needs heat energy to convert it into the electric energy it needs, thus saving a great deal of electric power cost. In addition, the later period of repair will be less compared. This kind of street light is really beneficial to the country and the people and has done many generations of work.

With the development of LED street lights, what is the current status of LED street lights? What kind of use characteristics of led street light distribution, the following Led street lights Manufacturers(CLASSICLEDLIGHT) for you to sort out the status and characteristics of light distribution of led street lights.

The illumination of the road surface is relatively uniform, and people or things on both sides of the road can also be seen, and the sudden situation can be known. The lighting of the street light meets the above requirements, and it's light distribution must be reasonable. Therefore, although the LED street light has the advantages of good light color, long life and dimming function, its light distribution level is still crucial. At present, LED street lights have just started and need to be constantly improved. Whether it is the optical structure design of street light or the heat dissipation technology, they are still being improved.

At present, the biggest feature of LED street lights for lighting is the function of directional emission of light, because currently, power led street lights are almost equipped with reflectors, and the efficiency of such reflectors is significantly higher than that of ordinary light reflectors. In addition, the efficiency of the self-reflector has been included in the LED road light effect detection. Road luminaires using led street lights should utilize the directional emission characteristics of LEDs as much as possible, so that each LED in the road luminaire directly directs the light to each area of the illuminated road surface, and then uses the luminaire reflector to assist the light distribution. Very reasonable road lighting integrated with light.

The above is the description of the light distribution status and related features of led street lights. If you have any questions, please feel free to contact us. We will continue to update more related content for you. You can follow our website for more instructions.

People are gradually beginning to feel the energy crisis. In view of this situation, the development of renewable energy has entered a new period, especially the development of solar energy and wind energy, which has attracted more attention. In the urban road lighting system, the traditional street light is converted into Solar led street light(CLASSIC) when they are upgraded. However, the solar LED street lights should be carefully maintained when in use, and then the correct maintenance method will be told:

1. Solar panels

For solar LED street light, the solar panel is the most important technology. In this case, in order to ensure the normal use of solar LED street light for a long time, it should be maintained. In the maintenance process of the solar street light, the maintenance of the solar panel is the key work. During maintenance, the key is to clean the dust on the top. The main purpose of this is to clean the dust on the panel because the existence of dust will affect the absorption of solar energy.

2. Wiring

During the maintenance of solar LED street light, the wiring is also very important, because, after a period of use, the wiring is prone to aging, which is likely to lead to unsmooth wiring connection. Therefore, during the maintenance of solar LED street light, attention must be paid to checking the wiring, the connection problems should be handled in a timely manner, and the aging wiring should be replaced in a timely manner, so as to ensure the normal operation of the street light for a long time.

3. Light

Maintenance of light and lanterns is also very important because lights and lanterns will carry a layer of dust after being used for a period of time, which will have an important impact on the light intensity of street lights. In order to improve the brightness of street lights, dust should be cleaned in time, and the brightness of lights and lanterns will also decrease after being used for a long period of time. Damaged lights and lanterns with very weak illumination must be replaced in time, otherwise, the light intensity at night will not be sufficient for passers-by to see the road conditions clearly.

During the maintenance of solar LED street light, the above-mentioned aspects must be done well, especially the maintenance of solar panels. This is also the difference between solar LED street light and traditional street lights. In this case, regular inspection and maintenance should be carried out to ensure the normal use of solar LED street lights, and regular maintenance can also prolong their service life.
