This also creates very good conditions for its future sustainable workability, which can effectively increase the working characteristics of its products to a certain extent, so that solar LED street lights can be more durable. When installing solar LED street lights, only guarantee LED The high efficiency of solar street lights can ensure the road to achieve good road lighting. Solar LED street lights are now more and more widely used in road energy-saving lighting. Because LED solar street lights are durable and energy-saving, they are relied on by government agencies or large enterprises in various countries, and LED solar street lights are used by street light manufacturers to reduce energy consumption. At the same time, the quality of road lighting is improved to ensure people's travel safety. The working principle of the solar street lamp is very simple, that is, the solar panel made by the photovoltaic special effect principle receives solar radiation energy during the day and converts it into electrical energy output. It is stored in the solar battery through the charge and discharge controller, and the illumination gradually decreases to About 101ux, the open circuit voltage of the solar panel is about 4.5v. After the charge and discharge controller measures this voltage, the solar battery discharges the lamp holder. Generally, the market pr
LED high-power floodlight maintenance
2020 / 11 / 09
Products such as LED high-power floodlights can really shine in the lighting effect, and their own characteristics and practicality can also meet the needs of consumers. So how should the product be maintained when it is not normally used? The first step for maintenance is to turn off the power of the LED high-power floodlight. This is a step that all lamps must be maintained for maintenance. Because doing so can ensure that the entire maintenance process is safe, and will not harm the product's circuit. So turning off the power is a must. Secondly, when cleaning, be sure to wipe it with a dry cloth. Wipes soaked in water will often cause certain damage to lighting fixtures, for example, if water drops into the fixtures, if this happens, it is irreversible for this type of product. Therefore, during the cleaning process, there must be no water stains. It is worth noting that when cleaning, do not use chemical substances to wipe, such as detergent, etc. These chemical substances often have a corrosive effect on the surface of LED high-power floodlights. Therefore, the maintenance work needs to pay attention to many aspects. In fact, the whole work is not difficult. Proper treatment of some details can often make the maintenance work have the corresponding effect.

Integrated street light of solar street light
2020 / 11 / 06
1 Introduction Solar integrated light, also called integrated solar street light, is a combination of high-efficiency solar panels, 8-year long-life lithium batteries, high-efficiency LEDs and intelligent controllers, PIR human body sensing modules, and anti-theft mounting brackets. Integrated solar street lights, also called integrated solar street lights or integrated solar garden lights. Because of its easy installation, integrated solar street lights are very popular in the market. 2. Working principle: The integrated solar street light is converted into electric energy by solar panels, and then the lithium battery in the integrated solar street light is charged. In the daytime, even in cloudy days, this solar generator (solar panel) collects and stores the required energy, and at night automatically supplies power to the LED lights of the integrated solar street light to achieve night lighting. At the same time, the integrated solar street light has PIR human body induction Function, can realize the infrared induction control light work mode of the intelligent human body at night, 100% bright when there are people, and automatically change to 1/3 of the brightness after a certain delay when there is no one, which saves more energy intelligently. At the same time, as a kind of "inexhaustible and inexhaustible" safe and environmentally friendly new energy, solar energy plays an important role in integrated solar street lights. Solar energy (Solar Energy) generally refers to the radiant energy of sunlight, which is generally used to generate electricity in modern times. Since the formation of the earth, organisms have mainly survived by the heat and light provided by the sun. Since ancient times, humans have also understood that the sun can dry objects and use them as a method of preserving food, such as salt production and salted fish. However, with the reduction of f
Comparison of the lighting principle of sodium lamp and LED street lamp
2020 / 11 / 05
At present, my country is creating a resource-saving and environment-friendly society, and the concept of "green lighting" is gradually gaining popularity. With the continuous advancement of science and technology and the rapid development of semiconductor material application technology, low-power LED light sources have been widely used in landscape lighting, and high-power LED street lights have attracted more and more attention from all aspects. The luminous principle of LED lights: LED (Light Emitting Diode), a light-emitting diode, is made of III-IV group compounds. It is a solid-state semiconductor device that can directly convert electricity into light. The heart of the LED is a semiconductor chip. The semiconductor chip consists of three parts, one part is a P-type semiconductor, in which holes dominate, and the other end is an N-type semiconductor. When the current acts on the chip through the wire, the electrons and holes will be pushed into the quantum wells. In the quantum wells, the electrons and holes recombine and then emit energy in the form of photons. This is the principle of LED light emission. The wavelength of light is the color of light, which is determined by the material forming the P-N junction. The luminous principle of high pressure sodium lamp: The high-pressure sodium lamp uses electricity to generate an arc between the electrodes at both ends of the arc tube. Due to the high temperature of the arc, the sodium amalgam in the tube is heated and evaporated into mercury vapor and sodium vapor. The electrons emitted by the cathode impact and discharge during the movement to the anode. The atoms of the substance gain energy to produce ionization or excitation, and then return from the excited state to the ground state; or from the ionized state to the excited state, and then return to the ground state in an infinite loop. At this time, the excess
Moisture-proof and anti-salt spray treatment of LED display
2020 / 11 / 04
For the application in coastal projects, the products can be processed from the following aspects: 1. The choice of LED lamp beads: In the humid environment of coastal areas, small LED lamps are prone to electrode migration, resulting in the so-called "caterpillar" phenomenon. In the project, we will choose a light tube with a larger luminous tube volume as much as possible while ensuring the dot spacing to reduce the "caterpillar phenomenon." 2. Protection of components: For exposed components, in order to reduce the contact with moisture and salt in the air, and to extend the service life of the components as much as possible, the surface of the components on the back of the box can be painted with three-proof paint . 3. Protection of LED lamp beads: LED lamp beads are an important part of the LED display. In order to ensure the service life of the lamp beads in the environment of high salt and high humidity, the surface of the LED lamp beads is coated with nano protective coating. This paint is a colorless, transparent material that forms a nano-protective layer on the surface of electronic components to completely cover the pins of electronic components, effectively preventing electronic product components from wading in water and being corroded by acid and alkali salts. Under the premise of not affecting the LED display effect, the erosion of the LED lamp beads by the external environment is reduced, and the service life of the LED lamp beads is increased.
How to check and repair the solar street light that does not turn on?
2020 / 11 / 03
1. First check whether the controller battery indicator light is on, if not, check whether the connection line between the controller and the battery is off. If the connection line is normal, check the battery voltage with a multimeter. The battery voltage is normal and replace the controller. 2. Check whether the load indicator of the controller is on, and check the output voltage with a multimeter to see if there is a voltage output. If there is no voltage output, replace the controller. 3. Do photovoltaic modules need to face south? It is best to face the photovoltaic module to the south. In order to ensure that the module can receive as much and even as possible light radiation, when designing the module bracket, we have made the best tilt design according to the regional sunshine situation. 4. Is the solar panel fragile? The solar panels are composed of fairly strong toughened glass panels, all of which have passed the hail test. 5. How much electricity can solar street lights produce? Different configurations have different power generation and lighting duration. We will recommend or design a street light configuration that can meet your requirements according to your lighting requirements and local actual conditions. 6. What happens if the solar panels are shaded? Solar panels should be installed in a place where there is no shade and can receive sunlight all day long. Even a small amount of shading will greatly reduce the power output of the system. In the initial site selection for the installation of solar street lights, places with obstructions should be avoided. 7. Should I clean the solar panels frequently? Under normal circumstances, it is not necessary to clean the solar panels frequently. In most areas, there is enough rainfall to clean the panels. If it is in a dusty area, timely cleaning is a must. It can be cleaned with a hose. Be careful not to step on or walk on the sol
Practical investigation of 6m solar LED street light
2020 / 11 / 02
The most widely used street lamps in the construction of new rural areas should be led street lamps or solar street lamps. They are mainly energy-saving and can ensure the lighting effect. They can kill two birds with one stone. Use solar street lamps in remote mountainous areas or areas with relatively low power system coverage. It is the most wise to choose the object, because it has the lowest requirements for the surrounding conditions, it can illuminate as long as there is the sun, the least picky and the easiest to form street light products, and the most cost-effective one is the 6-meter solar street light. With hot sales and high penetration rate, let's talk about the reason and inevitability of it below. The price of conventional rural 30-watt 6-meter solar LED street lights is more than one thousand four yuan and less than one thousand eight yuan, and the corresponding configuration can basically meet all regions of the country. The price range is because of the different places of use and the different lighting time requirements , The quotation is not unique due to different rainy and cloudy conditions, and it needs to be customized. You can contact the manufacturer. Solar street light manufacturers discuss the practicability of 6-meter solar street lights. The first thing to consider when making solar street lights is the height of the light pole. The height of the light pole is determined by the width of the road where it is used. It is said that basically four-way roads with auxiliary roads, so the natural road width must be more than ten meters, then the height of the light pole must be about 8-10 meters, and the auxiliary roads require solar street lights to be made of double arms. The arm is 80-100 watts, and the auxiliary arm is 30 watts, but if the basic road width in rural areas does not exceed 5 meters, this determines that the height of the light
What are the advantages of installing city power complementary solar street lights?
2020 / 11 / 01
With the rapid development of solar photovoltaic power generation technology, solar street lights have quickly been promoted and applied in the vast cities and rural areas, especially in the rural areas without power grids, and have achieved success. At the same time, many electricity has been installed Solar street lights have also begun to be installed on the urban roads of the route, but these roads are different from rural roads. If they are designed in the same way, on the one hand they cannot meet the requirements of urban road lighting, on the other hand, it also causes a waste of resources. Therefore, the utility power complementary solar street lamp can solve this situation well. The utility power complementary solar LED street light is composed of solar panels, solar street light controllers, batteries, lighting fixtures, consoles and power communication lines. Its advantages are very obvious. The following editor will introduce to you what its advantages are: 1. It can greatly reduce the cost of dual power supply for street lights in urban areas, reduce energy consumption, and conform to the concept of green and environmental protection. 2. Turn on the lights 365 days a week. Normal solar street lights are generally unable to keep on for multiple rainy days because of battery capacity and battery panel power design issues. The complementary solar LED street light from the mains can be automatically switched to the power source during rainy days, ensuring that the lights are on every day for 365 days. 3. Improve the service life of solar batteries. Complementary solar street lights with commercial power can reduce the number of cycles of solar batteries to a limited extent, which will inevitably increase the service life of batteries. 4. There is no need to arrange additional communication lines, and the cost is low, the communication error rate
Precautions for choosing installation location and embedded foundation for solar street lights
2020 / 10 / 31
With the continuous development of solar energy technology, solar street light products are becoming more and more popular. Many rural areas have installed solar street lights, but there are many things to pay attention to when installing solar street lights, especially when choosing installation sites and pre-embedded foundations. Will pay attention, so the use of solar street lights is not good, so what should we pay attention to when choosing the installation location and pre-embedded foundation? 1. Choice of installation location The installation site must have sufficient sunlight throughout the day, without any obstructions. Make sure that the installation site is far away from trees, high-rise buildings and other obstacles that will block the sun. There should be no direct light source above the solar panel, otherwise the street light system will not work properly. Solar street lights must be far away from heat sources , Otherwise the battery life will be greatly shortened. The foundation of the solar street light pole must be poured in a sufficiently solid clay layer. If the installation site is atypical soil layers such as sand or frozen soil, please inform us in advance so that we can take specific countermeasures. The solar panels must face south and ensure that the installation site faces south without obstructions. 2. Building the foundation Ensure that the inner test nut is screwed to the end of the thread, and leave enough length for the flange of the solar street light pole to ensure that the four bolts are on the same horizontal line. It is recommended to use a level to test and assemble the upper end of the thread with tape to prevent cement blockage Thread. Three, installation basis Dig the foundation pit according to the basic map provided by the solar street light manufacturer. At the same time, concrete can be prepar

2020 / 10 / 28
The courtyard lamp is an indispensable part of modern residential lighting. It not only has a high degree of viewing, but also harmonizes with the surrounding environment of the residential area. Courtyard lights use different shapes, different light colors and brightness to create scenery. So why does the community need to install courtyard lights? 2. The courtyard lights highlight the main landscape at night and can form a virtual and actual relationship with the surrounding environment of the community, enriching the night view of the community. Fourth, the courtyard light has the function of marking and reminding. The specific light can remind you about which area of the community. As mentioned above, it is necessary to install courtyard lights in the community. Generally, the height of the courtyard lights in the community is 3~4 meters, which is more in line with the night landscape of the community. The courtyard lamp is an indispensable part of modern residential lighting. It not only has a high degree of appreciation, but also harmonizes with the surrounding environment of the residential area. Courtyard lights use different shapes, different light colors and brightness to create scenery. Then, the height of the courtyard lamp is more in line with the night landscape of the community.
How to use traffic sign poles correctly
2020 / 10 / 28
How to use the traffic sign pole correctly? Traffic sign poles are a kind of sign poles, also known as traffic signal poles, highway sign poles, etc. His uprights are specially processed from steel pipes, and are usually hot-dip galvanized. They are often used to indicate traffic routes. Both sides of the highway, although seemingly simple, play a vital role in traffic. There should be corresponding requirements for the use and maintenance of traffic sign poles in regular places. On the one hand, it can ensure the service life of traffic sign poles, and on the other hand, the traffic sign poles can play the greatest role. In this regard, there are roughly the following types of general methods for traffic sign posts: 1. The setting of road traffic signs should be a priority project for road repair. Whether it is a new road or a modification or expansion of the original road, the traffic sign pole must be set up before vehicles can pass, and other traffic in the entire traffic road network The signs shall promptly adjust the corresponding information for the newly-built or modified parts. 2. The information on the sign pole must be displayed with professional signals, and the traffic information should be displayed as concisely as possible, so that people and vehicles passing by can easily and conveniently understand the location and related information. 3. Relevant departments should regularly clean and maintain the sign poles to fully ensure the visibility of new traffic information on them, and ensure that the traffic information on the sign poles can be clearly seen by the commuters celebrating. 4. The shape of the sign post should be selected according to objective requirements.
What factors affect the light decay of street lamps
2020 / 10 / 27
A question most recently reported by many customers is probably whether solar LED street lights will have light decay. The luminous decay of LED street lights means that after a period of time, the light intensity is lower than before. The factors that affect LED light decay are directly related to temperature and are determined by chips, phosphors and packaging technology. The following are two major factors that affect LED street light degradation: 1. The quality of the LED product itself: the LED chip used is not of good physical condition, and the brightness decays quickly; in addition, there are defects in the production process, and the heat dissipation of the LED chip cannot be well derived from the PIN pin, which causes the high temperature of the LED chip to increase the chip attenuation . 2. Use condition problem: LED is driven by constant current, and some LEDs are driven by voltage to make the LED attenuate; the driving current is greater than the rated driving conditions. In fact, among the many factors that affect the light decay of LED street lamp products, the most critical one is the heat problem, because many manufacturers do not pay special attention to the problem of heat dissipation in secondary products, which causes the degree of light decay of LED products to be more LED products that focus on heat dissipation are much higher. In addition, the thermal resistance of the LED chip itself, the influence of silver glue, the heat dissipation effect of the substrate, and the colloid and gold wire are also related to light decay.
Can you just choose the cheapest LED solar street light?
2020 / 10 / 27
In the early stage of street lamp procurement, many customers will ask how much solar street lamps are, whether you are a street lamp manufacturer, such as these questions, customers do not understand the production process of LED street lamps, nor do they understand the structure and principle of street lamps, just choose LED solar street lights are low-priced products. Of course, some customers have to purchase cheap LED street lights because they won the bid at low prices. However, this behavior is not desirable. This will only cause a lot of unnecessary troubles for the maintenance of street lights in the future, including the after-sales of manufacturers, without corresponding profits, how can there be high-quality after-sales service? The reason for the low price of LED solar street lights is probably the use of inferior methods such as cutting corners to reduce product costs. How can there be no problems with such LED lamps in the later application? How can the maintenance cost be low in the later period, and the safety cannot be guaranteed, which may eventually lead to customers repurchasing. This is tantamount to wasting financial resources, material resources and manpower. Therefore, when choosing a suitable price for LED solar street lights, we must choose LED solar street light manufacturers that have passed the qualification certification and product quality system certification. You can also inspect the strength of the manufacturer on the spot, check the welding and polishing of the goods, so that you can find a good manufacturer and buy a reliable LED solar street light!
Introduction to the knowledge of heat dissipation and light distribution of LED street light sources
2020 / 10 / 26
When it comes to LED light sources, the most important thing is heat dissipation and light distribution. In terms of heat dissipation, the main heat dissipation methods of LED street light sources are: heat radiation, heat conduction, heat convection and natural air cooling. Specifically, the heat generated by the LED light source is transferred to the heat dissipation aluminum, and then heat radiation and natural air cooling are performed through the area of the heat dissipation aluminum. When it comes to light distribution, it is mainly a lens and a reflector. Let's talk about the lens first: the lens is actually the secondary light distribution. The lens is divided by material: silicone lens, PMMA, PC lens and glass lens; because the silicone lens has good temperature resistance and small size, the diameter is 3-10mm, so It is directly encapsulated on the LED lamp beads; the lens used by our company is PMMA material, because this material is also very resistant to temperature, it is a large lens, and the quality is the best; while the PC material lens is produced The efficiency is high, but the light transmittance is slightly poor, and the temperature cannot exceed 110°; although the glass lens is resistant to high temperature, it is large in size, heavy in weight, fragile and high in production cost. Lens can be divided into primary lens and secondary lens according to application. The primary lens is directly packaged on the LED chip, but its light distribution angle is up to 180°; the light-emitting angle of the secondary lens can be adjusted arbitrarily. As for the reflector, it does not have a lens to emit light. Although the price is low, the temperature resistance is poor and the light is scattered.
Which light source is better for reading?
2020 / 10 / 25
1. Incandescent lamps, tungsten halogen lamps (note that there is also a metal halide lamp, with different principles and gaps in color rendering), low-quality energy-saving lamps, and low-quality LEDs. The strobe is more obvious (keyword: strobe depth). This information is basically not available on the Internet. If you are interested, you can watch the measurement results of EERE and other institutions. You can also use the photosensitive element to connect to the oscilloscope. If you save the point, use the mobile phone camera very close (within a few centimeters to bypass the mobile phone). Anti-stroboscopic algorithm of the camera) look. In addition, the stroboscopic frequency of incandescent lamps, halogen lamps, and energy-saving lamps is not 50Hz, but 100Hz. Energy-saving lamps with high frequency tens of thousands of flashes per second are actually 100Hz. The brainless propaganda in the market has confused the operating frequency of the switching power supply with the frequency of the output ripple. 2. The color rendering of incandescent lamps and tungsten halogen lamps seems to be perfect, but this is because the color rendering index itself uses black body radiation as the benchmark at low color temperatures. In fact, in recent years, academia has advocated examining the two factors of GAI and CRI as standards, while incandescent and halogen tungsten lamps are not very good in GAI. The specific manifestation is that they have poor color resolution and feel annoying. For serious study and work, it is recommended to choose a higher color temperature light source, such as 4500K-5000K color temperature, which is close to the natural sunlight outdoors, which is more suitable. 3. In theory, LEDs should not flicker, but due to cost and PF (power factor correction) reasons, most of the current drivers will flicker. In short, If you want to be economical and cost-effective, it is recommended to choose a t
How to distinguish the quality of LED street lights
2020 / 10 / 25
Even if the configuration is the same, the price of solar street lights from each manufacturer is different, so how do you judge the quality of led solar street lights? The quality of led solar street lights is not stated by the manufacturer. We have to verify from all aspects whether it is really a high-quality solar street light. First of all, look at whether the battery of led solar street lights is colloidal or lead-acid. Nowadays, lead-acid batteries have almost been eliminated. Secondly, look at whether the solar panels are made of crystalline silicon and which manufacturer is used. Secondly, look at the material and production process of lamp poles and lamp holders. At this stage, the lamp poles of regular manufacturers are all made of hot-dip galvanizing and plastic spraying. The surface of high-quality solar street lamp poles is smooth and shiny without obvious burrs. The lamp holder is of course better made of high-power LED lamp beads, and the quality and price of different lamp beads vary greatly. Some use the American Bridgelux lamp beads, through the secondary lens light distribution, the use of life and improve the efficiency of light. In addition, pay attention to the configuration of solar street lights. If the configuration is too small, it will not meet the lighting requirements. At the same time, the battery is often in a state of loss, which will also affect the service life. After reading the introduction of solar street light manufacturer Jinchuan Lighting, do you think that there is quite a lot of knowledge? Buying led solar street lights not only depends on price but also quality, this is the winner.
