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.
Led Public lighting(CLASSICLEDLIGHT) products have many features, we have summarized the following points to help you determine what is the best LED public lighting for your reference.
1. The best LED public lighting uses higher power LED chips.
Today, in order to reduce costs, some LED public lighting manufacturers use a large number of small energy LED 0.5W LED chips. However, this small energy LED has a very bad light decay, and its light decay and 80% lifetime are only 1000 hours. LED public lighting absolutely does not allow the use of such small energy LEDs due to long-term use. Higher power LED chips and well-known brands of LED chips are the best choice to avoid fast light decay.
2. The best LED public lighting has good heat dissipation.
For LEDs used in semiconductor components, the wafer is affected by temperature and, if the temperature is high, it will be reduced to 30% of the initial luminous flux. The service life of high-power LED public lighting theoretically has a lifetime of 30,000 to 50,000 hours, provided that it has good heat resistance. It is worth mentioning that the country has adopted the world's top producer of needle cooling technology.
3. The best LED public lighting is a lighter light.
LED public lighting Due to the high technical content of complex materials, composition, and other reasons, some higher energy lamp holders will weigh far more than ordinary high-stress sodium lamps, so support for your corresponding material specifications is higher. Despite this, some LED public lighting manufacturers have reduced the weight of LED lamp holders as much as possible, from the original single lamp holder to about 10 kg, dropping more than 50 kg, reducing weight and further decline. Lighter weight street lights require more cost and they are more likely to be the best street lights.
4. The best LED public lighting is an effective light with higher brightness.
LED lamp technology has become a mature high-power LED driver that can meet the luminous flux of general street lamps as needed. The commonly used high-power LEDs are 90 to 120 lm / W, and the best-LED chips and lenses can reach 180 lm / W. The higher the luminous efficiency, the better the energy-saving effect. This is one of the most important indicators for identifying high-quality LED public lighting. However, LEDs is not clearly defined in the routine, so it should be carefully verified when purchasing LED public lighting.
5. The best LED public lighting is easy to maintain.
LED public lighting is always installed on the top of the long pole, up to 3-10m or even higher. Reinstallation or maintenance will be difficult and cumbersome. Modular LED public lighting includes modular technology. Once one of the modules reaches its end of life limit, we don't need to place the entire lamp on the ground, just replace the damaged module. Therefore, this may be the trend of LED public lighting development.
The public lighting(CLASSICLEDLIGHT) is widely used in our lives. It can be seen everywhere on the road and in the community. Public lighting brings light to our night.
With the continuous consumption of energy and the scarcity of resources, the greenhouse effect is becoming more and more harmful to human beings. The pollution of the atmosphere of the earth is becoming more and more serious. The international demand for energy conservation and consumption reduction is getting higher and higher. The top priority of the work. China started the green lighting project as early as 1996 and proposed that outdoor lighting projects should save resources, prevent pollution, and benefit future generations. Over the years, through the joint efforts of all walks of life, as the fourth generation of light source semiconductor lighting products has made rapid development, and achieved remarkable achievements in energy conservation.
China's outdoor lighting accounts for about 30% of the total lighting power consumption, which is closely related to people's production and life. Street lights as an important application of public lighting, its superiority:
The long life of high-power street lights: the focus of this issue is very much, as the 50,000-100,000 hours described by many domestic and foreign experts and company product brochures, and optimistic, in fact, the life of high-power street lights depends on the following points:
(1) Chip quality and light attenuation value of the street light source.
(2) Package quality of street lights. Consistency and reliability.
(3) The street light acts as a cold light source, but the semiconductor itself generates heat. The heat dissipation of the street lights ensures good working conditions of the street lights.
(4) Life quality assurance of power supply and constant current drive.
An important parameter to measure the quality of led street light products is the qualified rate of led street lights. How to improve the qualified rate of led street lights is a problem that manufacturers pay close attention to. The following Led street lights Manufacturers(CLASSICLEDLIGHT) to explain to you the relevant instructions for improving the qualified rate of LED street light production.
In order to improve the qualified rate of LED street lights, we need to supervise the production process. In the whole production process, special personnel must supervise and manage to ensure everything goes smoothly from raw material procurement to a specific production. There is no problem in the process of linking up all links, which is the premise to ensure the qualified rate of products.
In addition, a good inspection of products is another important measure to ensure the qualified rate of light products. In other words, after the product is produced, it should pass professional inspection to ensure that the product is qualified, and then enter the market. In this way, when customers buy, they will have better quality products, and then we can ensure better use in the future. Of course, we can also get favorable comments from more customers.
Through the correct method, to improve the qualified rate of LED street light manufacturers' products, at this time we need to do a good job in the supervision of the production process, each step can not be careless. In the whole process of production, we must do a good job in the inspection of the products to ensure that the products are qualified before entering the market, so as to truly improve the qualified rate of the products.
Most of the public lighting in our life is Led Public lighting(CLASSICLEDLIGHT), because LED public lighting is different from traditional common lighting, LED public lighting is more energy-saving and convenient and different from common lighting, LED public lighting has a longer service life, and the most important thing is that it will not cause environmental pollution.
There are a lot of lights and lanterns around us that bring us more lighting, and we should know more information on the process of choosing to buy, for example, no matter what kind of lights and lanterns, their prices are different. LED public lighting will become the best choice for energy-saving renovation. Its power consumption is low, lighting efficiency is high, and its service life is long. Public lighting is the most important component of all our cities. Traditional lighting often uses some high-voltage lighting. The biggest drawback is a waste of energy. However, our global environment is deteriorating day by day, and all countries are developing some clean energy.
There is a serious shortage of power supply for LED public lighting. Energy conservation is the most important problem we need to solve. Therefore, it is of great significance to develop some new-type LED public lighting with high efficiency and energy saving life and high color rendering index for urban lighting energy saving. Road lighting is closely related to our life. With the acceleration of our urbanization process, the choice of lighting with low power consumption has better driving characteristics, faster response speed, higher anti-seismic capability, and longer practical life. These advantages of green and environmental protection cannot be taken advantage of.
The difference between LED public lighting and conventional lighting is that it is light source adopts some low-voltage DC power supply, which has high efficiency and safety, energy-saving and environmental protection, long service life, and fast response speed. The manufacturing temperature of the outer cover is 130 degrees, reaching minus 45 degrees. However, it has the characteristics of the unidirectionality of light, no diffusion of light to ensure the lighting efficiency. Even it has a unique secondary optical design. The lighting of LED public lighting is incident on the illuminated area to further improve, and the lighting efficiency achieves the purpose of saving energy.
Under the current market conditions, what is the current status of Led Public lighting(CLASSICLEDLIGHT)? What are the drawbacks of the LED public lighting distribution method currently used? The following is a description of the relevant instructions for LED public lighting.
There are two types of led public lighting in the current market. The first one is to use a traditional road lighting enclosure, but in the luminaire, a matrix is mounted on an almost flat mounting surface (also a reflective surface). LED, the second method is to concentrate multiple LEDs in a circular area (area diameter 30~40mm), so that the light output density of this small area is close to that of high-intensity gas discharge lamps, and then use the luminaire reflector Perform light distribution. Among them, the light quality of the LED public illumination designed by the first method is not very good, and the second method has the problem of poor heat dissipation, which leads to the reduction of the luminous efficiency and use of the LED public illumination. The problem of reduced life.
An LED with a reflector and a reasonable beam output angle has a good primary light distribution. In the luminaire, the installation position of the LED common illumination and the direction of the emitted light can be designed according to the height of the street lamp and the width of the road surface, so that a good secondary light distribution function can be realized. Reflectors in such luminaires are only used as an auxiliary three-time light distribution to ensure better road illumination uniformity.
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.
The public lighting(CLASSICLEDLIGHT) is closely related to our lives. In addition to ordinary street lights, more and more public lighting has entered our lives. We must pay attention to some details in the installation of public lighting. Selection of disassembly and assembly locations for public lighting. The disassembly location should be near the installation site to facilitate post-assembly transportation and avoid working on rainy days.
Inventory the luminaire according to the shipping list. Disassemble and refer to the packing list to check each part and check for damage such as bumps, abrasion, deformation, and scratches. The pole assembly and wear-resistant accessories (such as solar modules, lamp holders, etc.) must be placed with a soft mat that is soft to avoid unnecessary damage such as scratches during installation. When the lower pole assembly is placed, an iron frame support is required at the upper end to facilitate the installation of the pole assembly. Street lamps are closely related to our lives. In addition to ordinary street lamps, more and more public lighting has entered our lives. We must pay attention to some details in the installation of public lighting. Selection of disassembly and assembly locations for public lighting. The disassembly location should be near the installation location to facilitate post-assembly transportation. Try to avoid working in the rain.

Through practical application, it is demonstrated that the high-power public lighting has the advantages of energy-saving, environmental protection, long life, adjustable brightness and color temperature, and high color rendering. With the maturity of LED technology and the continuous improvement of efficiency, LED solid-state lighting is the trend and the best solution for energy saving. The energy-saving features of public lighting systems are primarily determined by LED chips and power supplies. However, the LED chip and the power module are integrated, and the space is generally small, and the heat dissipation is poor. The LED chip and the power source are both heating elements so that the ambient temperature is high. Therefore, this paper reduces the ambient temperature by improving the heat dissipation conditions of the public lighting system, improving the luminous efficiency of the LED and the efficiency of the power supply, so that the LED power source and the life of the LED chip are matched to achieve true energy saving, environmental protection, and long life.

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.
