Solar road study, also known as solar cast aluminum road lamp, reflective mark, LED road spike lamp, etc., uses solar panels to charge, store energy in the battery, and automatically light up when the light is insufficient at night and in rainy and foggy weather, which can well guide the vehicle to the correct direction and effectively ensure traffic safety.
What we want to talk about is highway spike (the nature of railway spike is completely different from this) which is also called raised road sign. The spike is also divided into many kinds, such as reflective spike, plastic spike, cat’s eye spike, etc., which have different names according to different functional materials.
Solar Road Stud Application:
The road section with more than four lanes back and forth, but no isolation belt in the middle and insufficient light at night;

Solar traffic lights are powered by solar panels and are quick to install and easy to move. It is suitable for newly built intersections with large traffic flow and urgent need for new traffic signal command and can meet the needs of emergency power failure, power restriction, and other emergencies. Here’s how solar-powered traffic lights work.
How do solar traffic lights work?
Solar panels, powered by the sun to generate electricity, and charge battery through the controller, the controller has overload, over-discharge and short circuit protection function, automatic identification during the day and night, automatic storage battery voltage protection, easy installation, no pollution, etc. The battery discharges the signal machine, transmitter, receiver, and signal lamps through the controller. After the signal machine adjusting the preset mode, the signal will be generated and sent to the transmitter. The wireless signal generated by the transmitter will be transmitted intermittently. The transmitting frequency and intensity of the wireless signal are in line with the relevant regulations of the National Radio Regulatory Commission and will not interfere with the wired and wireless electrical appliances around the use environment. At the same time, ensure that the transmission signal has a strong ability to resist strong magnetic field (high voltage transmission line, automotive electric spark) interference. After receiving the wireless transmission signal, the receiver controls the light source of the signal lamp and realizes that the red, yellow, and green lights work in the preset mode. When the wireless transmission signal is abnormal, the function of the yellow flash can be realized.

Many workers also report that battery equipment is being damaged or removed and stolen, it is really a challenge to replace and repair. Not only is the cost of the battery itself high but also if stolen, replacements are costly and can create safety concerns on private and public roadways that hold the street lights, this will cost a lot of money and working hours to replace.
In order to reduce the theft of solar street lamps, the safety of the equipment can be strengthened from the following aspects：
The cost of solar street lamps is higher than conventional street lamps, and the anti-theft and stability measures are not matured as research continues on the technology. Users should continue to monitor the security of the solar street lamps where they are easily stolen. They can set up a monitoring system or install an alarm system in order to be informed of thieves stealing equipment in a timely manner. At the same time, customers should also enhance their sense of responsibility and increase some awareness of theft.
The selection of a standard and/or qualified control box, and other solar street light materials are very important in the installation process to ensure that the firmware meets the requirements, as well as to ensure the strength of the solar street light. This, to a certain extent, can also play the role of anti-theft deterrence. If we make a quality battery and bury our batteries underground, we can continue progress in the role of anti-theft prevention. Cover the battery in soil/sod to enhance its concealment to pedestrians.
LUXMAN integrated solar street lamp (also known as solar integrated street lamp/solar garden light) The integrated design of our solar street lamp, with anti-theft solar street light screw design, can reduce the risk of stolen batteries and components of solar street lamps. Some customers even equip the light pole with anti-theft wire.
The split-type solar street light battery is easily stolen because it is found on the side of the road. It is common for solar batteries to get stolen, so everyone should be more aware to prevent theft. There are anti-theft packages available to support loss prevention, one of the best ways is to build a land cage and embed the solar street lamps. You can use an upper threading pipe secured 300 mm in the ground, casting a surface finishing level, in the case of lamps and lanterns. Anti-thief Solar street lamps have more expensive colloids and a maintenance-free battery is stored in the battery box, then put about one meter into the ground or cement pool, so after reinforcement, the battery will be safe from environmental hazards and dangers due to theft.
So how can we improve on our anti-theft measures in solar street lamp equipment? We can mainly begin from the following three options.
The choice of the battery itself
Accumulators generally have three places to install: Underground, light poles, and solar panels on the back. The basement is the most convenient to steal from, so we suggest the best installation from the light pole or solar panels on the back.
We commonly use two kinds of batteries: Lead-Acid batteries also known as colloidal batteries, and lithium-ion phosphate batteries. The Lead-Acid batteries are larger than the lithium-ion phosphate batteries, both in volume and in weight. It increases the load of solar street lights, so it is more efficient to choose a lithium-ion phosphate battery that is lightweight, smaller in size, and holds a high efficiency.
It is best to choose an integrated solar street lamp because integrated solar panels, batteries, LED light sources, and controllers together are highly efficient, simpler to install, and safer to maintain.
If the user wants to install the battery on the ground, it should not be without anti-theft solutions. The best way is to use the cage encapsulation because the battery is placed in a special moisture-proof box, and then put into the ground about 1.2m into the cement pool. The net height of the cement pool should be about 0.5 meters.
After the reinforcement treatment, cover with a 5cm thick prefabricated cement board cover, and then weld the cement plate steel and light pole base steel together, as well as the landfill and tamp can. In addition, solar street lights should also be installed in a safer place, if too remote, the risk of being stolen is greater.
3.battery preventive measures
If you want to further confirm the safety of the battery, you can also install additional security or an alarm system. This will allow you to pay attention to the use of solar street lights in real time, if someone tries to steal the equipment, the alarm system automatically alarms. With preventative security deterrence, it can be more convenient to manage solar street lights and prevent theft.
The Solar street light pole is usually made of steel, which is characterized by beautiful, durable, solid, easy to make various shapes, simple processing technology, and high mechanical strength.
At present, more and more farms, courtyards, rural roads, and urban communities have been installed with solar street lights. Because the solar street lamps are exposed outdoors for a long time, the performance of the lamp pole itself must pass the customs, otherwise, it is likely to be rusted in the sun and rain, which will not only affect the aesthetics but also increase its risk. Below are some basic requirements for supporting the poles commonly used to support solar street lamps?
The cross-sectional shapes of commonly used tapered light poles are round and hexagonal, and some also use octagonal shapes. The taper is mostly 1:90 and 1: 100. and the wall thickness is generally 3-5mm according to the stress of the lamp pole.
The working environment of the solar street lamp is outdoor, so the requirements for supporting the lamp post are better. To prevent the lamp post from rusting and corroding and reducing the structural strength, the lamp post must be anti-corrosive.
The anti-corrosion method is mainly to take some preventive measures against the cause of rust. The anti-corrosion method should avoid or slow down the effects of humidity, oxidation, high temperature, chloride, and other factors. The common methods are as follows:
Plastic spraying treatment: spray plastic treatment after hot-dip galvanizing. The plastic spraying powder should be selected for outdoor use, and the coating should not be peeled or cracked. Spray plastic treatment can improve the corrosion resistance of the steel pole, and greatly improve the beauty and decoration of the lamp pole. The color can also be a variety of choices.
Hot-dip galvanizing: The process and method of immersing the pre-processed parts in the molten zinc solution to form a zinc and zinc-iron alloy coating on the surface. The thickness of the zinc layer is 65-90um. The zinc layer of the galvanized parts should be uniform, smooth, free of burrs, drippings, and excess agglomeration. The zinc layer should be firmly combined with the steel rod, and the zinc layer should not peel off or bulge.
Due to the solar street light controller and other electrical parts are installed in the lamp pole (some battery is installed inside a light pole), so you also must pay attention to a waterproof light pole and anti-theft performance, prevent the rain into the lamp post cause electrical failure, maintenance to avoid the use of conventional tools can open (e.g., hex socket bolts, pliers, etc.), prevent theft or damage.
The arrival of the cold wave is undoubtedly “adding insult to injury” to many solar street lamps. Recently, many solar street lamp users have reflected on the network platform that street lamps will have different degrees of problems such as shortened endurance, slower charging speed, and inability to charge in low temperatures in winter.
Why is LiFePO4 battery life attenuation more serious than ternary lithium battery at low temperature? In fact, this is due to the structural differences of LiFePO4. The ternary material is Ni-Co Mn, which is arranged in a layered structure, but LiFePO4 adopts an octahedral olivine structure, so the LiFePO4 battery has better stability performance and more controllable capacity attenuation.
However, the structural differences also lead to the lower capacity of the LiFePO4 battery. The ions migrate easily in the hierarchical structure of ternary lithium, but the octahedron has greater resistance and lower activity during the migration process, and its power is more easily affected by the external temperature environment.
The capacity retention rate of LiFePO4 batteries is about 60-70% at 0 ℃. It decays to 40-55% at – 10 ℃ below zero, and only 20-40% at – 20 ℃. The ternary lithium battery can still maintain the normal battery capacity of about 70% – 80% at – 20 ℃, which is the reason why the solar streetlights equipped with LiFePO4 battery have a more serious life loss in winter.
Finally: in a short period of time, the problem of winter solar light endurance attenuation in winter is still “no solution”. It is undeniable that at present, solar streetlights have many advantages, such as power saving, easy installation, high intelligence and so on. But can users accept the shortboard with reduced endurance in winter? Perhaps manufacturers should point out the problem of low-temperature lighting to users when they publicize street lamps, instead of waiting until winter to complain that the lamps they buy are only on in the middle of the night or not at all. Of course, after spring, the winter solar light will return to its original state. er so
In recent years, due to the advantages of green energy, easy installation, and wide application, which can be installed in remote areas without connecting power grid, solar street lights are waiting for more and more installation and use. How to choose the right solar light battery for your project? LUXMAN summarizes many years of experience and makes the following analysis for you:
suitable for split solar street lights. The earlier split solar street lights are mainly composed of solar panels + GEL batteries + LED lamps. Among them, the solar panel needs to be equipped with a fixed bracket, and the GEL battery needs to be packed in the battery box and buried underground or hung on a light pole. The configured LED lamps generally require a certain length of wiring. It is inconvenient to install, and the product cost and labor cost are high.
At present, more split solar street lights use lithium battery box technology, that is, pack a lithium battery pack and controller into a box, usually placed on the back of the solar panel, and some are placed on the bottom of the LED lamp, using an intelligent control system.
Lithium battery pack, there are currently three commonly used lithium batteries of 18650, 26650, and 32650. Relatively speaking, 18650 is usually a ternary lithium battery, no matter the service life and cost performance are not high. Currently, the commonly used LiFePO4 battery specifications are 26650 and 32650. 26650 means diameter D=26mm, length L=65mm; 32650 means diameter D=32mm, length L=65mm. Due to cell size limitations, the battery capacity of the 26650 is not as high as that of the 32650, and the number of batteries using the 32650 to achieve the same configuration is less than that of the 26650.
For example, an 80W integrated solar street light needs a 12.8V 72AH LIFEPO4 battery. The 26650 cell capacity is 4000mah, and the 32650 cell capacity is 6000mah. If 26650 is used for 12.8V 72AH battery pack, 4S18P 72pcs cells are needed, and 32650 is 4S12P 48pcs cells. With the same configuration, the number of batteries using 32650 will be 24pcs less than that of 26650. In terms of price, the current price of 26650 battery 1AH is about RMB 20.00, and the price of 32650 battery 1AH is about RMB 14.00. In this case, if a 26650 battery is used, the battery composition costs 72*20=RMB1440.00, and the cost of using a 32650 battery 72*14=RMB1008.00, the cost gap is obvious. Therefore, the 32650 is cost-effective.
The use of LiFePO4 large-capacity batteries is a trend. The cost of solar street lights will be lower and lower, but the quality depends on the factory’s production technology and the ability to control raw materials.
For products with the same appearance, the lower the price, the more you need to be cautious, because regular manufacturers use high-quality raw materials, and the price of high-quality raw materials will not be too cheap. LUXMAN solar street lights use high-quality raw materials, and our quality has been affirmed by customers in the past few years.
In a short period of time, the problem of attenuation of the battery life of solar street light in winter is still “unsolvable”. It is undeniable that the current solar street lights have many advantages such as power saving, easy installation, and high intelligence.
Perhaps the manufacturer should indicate to the user the problem of low-temperature lighting when advertising the winter solar street light, instead of waiting until the winter to complain that the lights they bought only light up in the middle of the night or do not light up at all. Of course, when the spring flowers bloom, the lights will return to their original state.
Solution 1A: Manually remove snow and ice in time.
In high-latitude countries, heavy snow and extremely cold weather in winter can easily cause solar panels to be covered by heavy snow, resulting in low charging efficiency or inability to charge. It is necessary to clean the surface of solar panels in time, remove snow and ice, and try to replenish electricity.
Solution 1B: Automatic snow removal and deicing.
In addition to manual snow removal, ice removal, and dust removal, solar street lights with automatic cleaning tools can also be effective.
Solution 2: Increase solar panel power and battery capacity.
This scheme is relatively simple. The increase in battery capacity and the corresponding solar panel also increase, which can provide additional power for street lights and extend the number of lighting days.
It is feasible to increase the solar panel alone without increasing the battery. Objectively, it can charge more batteries in a shorter period of time, which is particularly important in winter.
It doesn’t make sense to increase the battery alone without increasing the matching solar panel. Because the charging efficiency of the original solar panels is fixed, if the charging is insufficient every day, the added battery AH is wasted.
Solution 3: Shorten the lighting time.
Shorten the lighting time of solar street lights every night through remote control settings. For example, the standard working time is 12 hours per night, adjusted to 6 hours. That is, the lights are turned on in the first half of the night, and the lights are not turned on in the second half of the night. This reduces battery energy consumption and extends the number of lighting days. But at the same time, there is a problem, that is, the nighttime in winter is longer, so shortening the lighting time is not very scientific.
Solution 4: Set up the battery insulation package.
Design a heat preservation plan for the battery pack. When the temperature is lower than a certain value, the system can automatically heat up and automatically shut down when it reaches a certain temperature value. This can ensure that the battery pack works within a temperature range to achieve optimal use. The technical difficulty is a bit high, and only a few companies can do it.
Solution 5: Increase wind power generation.
From pure solar panel power generation, it becomes both solar power generation and wind power generation. Adding a channel for supplementing electricity greatly improves the charging efficiency of the battery. At the same time, we must pay attention to adding wind turbines, the cost will be higher.
Solution 6: The mains power complements each other.
Add an AC power adapter, which will be replenished by the mains when the battery is short. Controlled by the main controller, priority is given to using solar power, and when the battery power is insufficient, it will automatically switch to mains power. At present, this program is mature. It is the first product to be launched in the Nordic countries, and it has been successfully installed. Can fully meet the lighting needs.
In summary, as an outstanding leader in the solar street light industry, LUXMAN has developed products that are not only rich in variety and excellent in appearance, but more importantly, we rely on more than ten years of product production experience, customer feedback, and stricter environmental protection. skills requirement.
In recent years, all-in-one solar street lights have been used in many projects, and they are favored by many engineering companies because of easy installation.
We would like to share some mistakes that consumers would make during purchasing.
Mistake 1: The same configuration, choose the lowest price.
Solar street lights cannot simply look at the appearance and configuration. For products with the same appearance, the shell and battery are different, which has a great impact on the price. The same aluminum or ABS material, the shell thickness is different, the cost difference is obvious. There are differences between brand new and second-hand batteries, and the prices of battery products from different manufacturers are also different. Therefore, cooperation with powerful companies is far better than low-priced products. During our warranty period, for any product in question, we will send parts for free, and remotely video guide the operation, including shipping costs. In this way, customers can not only accumulate reputation and orders but also avoid the troubles caused by bad products.
Mistake 2: Count the number of lamp LEDs to determine the LED power.
The more the number of LEDs, the brighter or the greater the power. Customers who have no physical foundation or some common sense of electronic products simply think that the more the number of LED beads in a lamp, the greater the power, and the simplest method of calculating the lamp beads are used to determine the power. But in fact, this method is unscientific and falls into the trap of the seller, because it is the voltage and current output by the controller that determines the power of the street lamp. Although the LED lamp module itself has more lamp beads, the higher the power can be made, but it is not appropriate. The voltage and current of the LED module can’t reach the nominal power, it’s just self-deception.
Mistake 3: The higher the power of solar street lights, the better.
There are roughly two ways to express the power of solar street lights: one is to express the power of the street lamp in the name of lamp Leds; the other is a product based on the voltage and current output by the battery controller, and the actual 100% full power is on. The power of the lamp is the actual maximum power. The first way of expression is more common in the market. This is a routine of sellers. The second way of expression is more scientific, the light power is written according to the actual, and there is no sense of deception. We only recommend the second way of solar street lights. According to the actual power of solar street lights, is the higher the power, the better? Obviously not, the suitable street lamp is the best. Because street lights of different power have different requirements for the installation height, such as 30W solar street lights, the recommended installation height is 6-7 meters. If a 60W street light is installed, there will be several impacts: 1 cost increase, 2 consider the side length of the lamp body If it is blocked, the installation will also affect. 3 Some customers have complained that the light is too bright and affects sleep. Therefore, the best choice is a solar street light with a suitable height and suitable power.
France Dassault: A beautiful plane must be a good plane. In the same way, the product design of the new integrated solar street light we designed is based on the shortcomings of the previous generation products, and we have also consulted many customers’ feedback and requirements. Both the appearance and the built-in are first-class products. The appearance adopts a streamlined design, the top is bird-proof, and the integrated waterproof design does not require glue during production and meets the waterproof requirements, which can shorten the working hours and be more environmentally friendly. The whole lamp has passed IP66 certification. The internal design is modular, including LED modules, controller modules, and battery modules, all of which can be replaced quickly, making maintenance easier and more convenient.

HPS lamp (high-pressure sodium lamp) has been a confident leader in grow lighting system market for decades, and the rapid development of LED and Solar technology is likely to change its position. In this article, we will carefully study the differences between different types of lights and try to comment on their expectations
So what is HPS Grow Light, LED Grow Light, Solar Grow Light?
HPS Grow Lamps
HPS lamps emit light by passing high-pressure pulsed energy through a sealed quartz tube filled with sodium vapor and other elements such as xenon and mercury. When heated, the gas starts to glow. Sodium gives off a strong orange, yellowish light. Xenon and mercury can be used to change the spectrum, which emits in the blue range of the visible spectrum, making the light whiter.
LED Grow Light
A light-emitting diode (LED) grow lights are semiconductors that allow current to pass almost unimpeded in one direction, but provide very strong resistance in the other direction (through the “PN junction”). On one side of the junction, the material is processed in such a way as to receive additional electrons; on the other side, on the contrary, the material with not enough electrons is processed. By applying a voltage, we force electrons to move through the junction to fill the “gap” on the other side. This results in luminescence, the color of which depends on the material used. Phosphates and nitrides of gallium, aluminum, zinc and silicon are most commonly used.
Solar Grow Light
Solar Grow light powered by solar panels, is a way that can allow saving the amount of energy consumed by the traditional grow lights for both their indoor and outdoor applications, Outdoor Solar Grow light is not influenced by the power grid as it is a stand-alone lighting system powered by the sun. This solar grows lighting system provides clean energy, effective, convenient.
The efficiency of an indoor plant lamp can be expressed by a simple formula: the total amount of light energy (lumens) of the lamp is divided by its total energy consumption (watts). The minimum power of the DNAT is 90 lm/W, although for some brands this figure reaches 150 lm/W or more. Increasingly, growth lamps are also evaluated in units of photosynthetically active radiation (PAR), which is measured in mol/s(photons per second per 1m2 of plant surface).
µmol / s is an increasingly popular metric for plant lights because it measures the amount of light reaching the plant rather than what the human eye sees.
For plant light, LM/W is considered to have less ‘discourse power’ than PAR. This is because the LM/W of red and blue lamps is typically much lower, as they produce the most important frequency for photosynthesis, and the production of “inefficient” light is minimized.
However, newer led grow lights use multiple frequencies to create a richer, more efficient, and more complete spectrum, which is believed to be beneficial for plant growth, and usually include discrete white LEDs as well as red and purple. These newer panels sometimes express efficiency in LM / W. Well-known manufacturers should at least instruct par. For example, but master’s 410W full spectrum panel (bandmaster II 675 God) indicates par values at different distances from the lamp (the longer the distance, the lower the par, because fewer photons will hit the plant surface). At 31cm, the par of the lamp is just over 2000 μ mol / s.
Although advances have not prevented the development of HPS technology, it is believed that these lamps only have a faint appearance of natural sunlight compared to more modern lighting systems. If xenon and mercury are not added, the sodium itself glows red and yellow. However, there are new full spectrum led grow lights that actually have two arcs, i.e., they are a mix of DNAT and DRI. So, for example, the Hortilux Super Blue HPS/MH combines 600W HPS and 400W DRI to provide an initial 110,000 lumens and simulate the spectrum as close to nature as possible.
It is our goal to provide products with stable quality for customers.
