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

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

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.

How to troubleshoot if solar street lights are not on
2020 / 10 / 19
Solar street lights use solar energy as energy source, and work outdoors is greatly affected by natural factors. After using for a long time, the battery board is too dusty or covered by snow in winter, the photoelectric conversion rate is reduced, the charging is insufficient, and the battery power is insufficient. Therefore, after installing solar street lights, we should organize personnel to conduct detailed inspections on the battery panels on a regular basis. This is to keep the battery panels running under good working conditions for a long time, to ensure the normal use of the street lights, and to create more economic benefits. Method/step: 1. Check whether the battery board is damaged, find out and replace it in time. 2. Check whether the battery board connection wire and the ground wire are in good contact, and whether there is any falling off. 3. Check whether the battery board bracket is loose or broken. 4. Check whether there is any covering around and on the surface of the battery panel. 5. Check the bird droppings on the surface of the battery panel and clean it if necessary. In addition to the cleaning and protection of the solar panels, there are also solutions for the maintenance of the solar cell array: 1. In the event of strong wind, heavy rain, hail, heavy snow, etc., measures should be taken to protect the solar cell array to avoid damage. 2. The lighting surface of the solar cell array should always be kept clean. If there is dust or other dirt, it should be rinsed with clean water first, and then the water stains should be gently wiped dry with a clean gauze. Do not rinse with hard objects or corrosive solvents. , Exploring. 3. The battery pack matched with the solar cell array should be used in strict accordance with the battery maintenance method. 4. Regularly check the wiring
How does the solar street light controller control the time?
2020 / 10 / 17
The solar street light controller is an important part of the solar street light. It has serial communication data transmission function, manages the charge and discharge of solar street lights and remote intelligent control, and can control the time of solar street lights on and off. But many people don't know how to control the time of solar street lights when using solar controllers. The technician Wang from the solar street light manufacturer below tells everyone this principle. . The solar street light controller can control the two things: the time when the street light is turned on and the duration of keeping the light on. Usually, the solar street light controller does not have a built-in clock, and it does not have a built-in clock. The lighting time is usually triggered by monitoring the current value generated by the solar panel. The current value is usually set to 5ma. Using the solar panel's use time, you can adjust this value accordingly. The new solar street light controller supports multi-time adjustment and control. The lighting power of LED lamps can be set in different time periods and should be adjusted according to actual needs. The adjustment time of each solar street light controller is different. It has an infrared interface, a dedicated data line, and can adjust the network through the network. The best solution is to let the supplier help you before leaving the factory. Complete the operation. Generally, the solar street light controller does not have a built-in clock, and it usually does not operate according to the clock. The lighting time is usually triggered by monitoring the current value generated by the solar panel. The current value is usually set to 5ma. Using the solar panel's use time, you can adjust this value accordingly. The new solar street light controller supports multi-time control. The lighting power of led lamps can be set in different time pe
