How to repair solar street lamp?

Nowadays, solar energy application technology is becoming more and more mature, and the use of solar street lamp is becoming more and more extensive. It is inevitable that there will be faults when using solar street lamp. If there are faults, they should be repaired. Check out how to repair solar street lamp with SRS solar street lamp manufacturers.

One, the solar street lamp maintenance common fault

1. Battery problems. If the light time is short, battery energy storage decline, resulting in rainy weather, light time is short, that is the battery problem, should replace the battery.

2. LED light source problem. Solar street lamp beads are not completely bright, in addition to the quality of LED light source itself, is the welding problem, should to replace the lamp beads in time or weld them firmly or replace the lamp caps more directly.

3. Installation site problem. solar street lamp installation sites, the sun light is insufficient, can not give the battery storage is also a big problem. Should be find out the solar street lamp system suitable for this kind of place to meet the lighting requirements.

4. Line problems. Poor line connection, battery feed, energy storage decline, will cause lights flashing. The wires should be replaced or repaired in time the road touches a bad place.

What would be the problem if the whole light didn’t work? First, check whether the controller is filled with water. If it is not the problem of the controller, measure the electricity whether the pool has voltage, whether the voltage is lower than 10.8v, if not, then check whether the panel has voltage, if there is no voltage, change the battery plate.

Two, the solar street lamp fault solution

The light is not bright possible faulty components: LED light source, solar controller, battery, solar panel.

Solutions:

1. Check whether the wiring terminals of the lamps are loose. 

2. Remove the LED light source and connect it to the battery or DC12v power supply to see if the light works normally do, pay attention to the positive and negative electrode, the light does not light is the LED lamp fault, need to replace the LED lamp, the light on the controller or battery fault. 

3. Measure storage

If the battery power is lower than 11v, it means the controller is in the protective state, and the lamp can be fully charged before use. If it is higher than 11v, it indicates that the controller fails.

The controller needs to be replaced.

Common faults and solutions of LED bulbs

Now, led lights are very popular, slowly replacing incandescent lights. Because of its high brightness, low consumption, many styles and beautiful appearance, it is very popular among consumers. But after using for a period of time, LEDs will become dimmed or the lights will flicker. What’s the matter? Today, we will analyze the common faults of a led light bulb and the corresponding solutions.

There are two popular LED lights on the market, one is constant current and the other is resistance-capacitance. Relatively speaking, the constant current is relatively stable. There is a controller, and the current is stable output. The resistance-capacitance structure is relatively simple, but the voltage reduction process is performed to make the LED lamp bead work within the normal working current.

There are actually many small lamp beads inside the LED lamp. They are usually connected in series, and then combined in series and connected in parallel.

Next, we can look at the explanation on the controller, the input is 220 volts AC, the output is 20-30 volts, and the small LED beads are all DC.

Fault 1: LED does not light up

1. According to the description of the manipulator, first of all we have to check the input end of the manipulator and whether the 220 volt power supply is normal. Then check whether the output of the 20-30 volt DC power supply is normal. When the power supply is normal, let’s check the LED lights.

2. It can be measured with an electric pen. The light bulb is mostly caused by the problem of the controller, so if you check the output end is abnormal, replace the controller, if you can work well, you can also disassemble and find the reason and start to correct it yourself.

Fault 2: LED is dim

The dimming of the LED lamp is usually caused by the failure of some of the lamp beads, so we can check the quality of the lamp beads one by one with a multimeter. Of course, it is also possible that a group of lamp beads is broken. Find out the broken lamp beads and replace them according to the type. This also requires a certain amount of work.

For the diode gear of the multimeter, use the red and black test leads of the multimeter to touch the positive and negative poles of the lamp beads. If the lamp beads are on, it is good, and if the lamp is not on, it is broken.

Fault 3: LED light is dimly bright

Generally, poor-quality LED lights have this situation, and the lights are turned on and off to the zero line without paying attention to the lights at home. LED lights are very sensitive and can light up with weak currents. All households use electronic switches to turn off the lights. No matter what kind of situation causes the dim brightness, we can use a relay to solve it perfectly, because the relay Control the live line and the neutral line at the same time.

What to pay attention to when choosing LED bulbs

The rapid growth and popularity of LED lighting products have gradually replaced traditional light bulbs. What should be paid attention to when choosing led light bulb? Next, Guangli will tell you three aspects of choosing led light bulb.

1. Choose brightness

Luminance is the rate of light energy emitted by the light source or the rate of light activity. Lumen is a unit of measurement to measure the rate of light output. The light output of a 400-lumen led light bulb is equivalent to a 35-watt incandescent bulb. The energy consumption is only 6.3 watts. Generally speaking, if it is a led bulb, it is about 1 flat space requiring 1-3 watt bulbs, and customers can choose according to practical needs.

2. Power consumption

Energy-saving lamps consume much less energy than traditional incandescent bulbs, so you can choose based on light output (lumens) instead of power consumption (watts). Watt is a measurement unit for measuring power consumption.

3. Color temperature

In our eyes, the light emitted by most light sources is commonly referred to as white light. In practice, the white light emitted by different light sources that the naked eye looks like will have different colors depending on the color temperature. The more bluish the light color, the higher the color temperature, and the more reddish the light color, the lower the color temperature. Bulbs with more red spectrum light are more gentle and are ideal for relaxing or general lighting, while cool-toned lights are suitable for work or to gather light.

Good mask, made by Gree;Good solar street light , from SRS

Due to the influence of COVID-19,surgical masks are widely used, BYD, Gree, Foxconn, BYD, SAIC-GM-Wuling, Sinopec, Guangzhou Automobile Group and other companies have entered the mask market. As Dong Mingzhu shouted “good masks, Gree made”, a mask dealer Understanding the notes indicates that the real catfish is here.

In the past, “As long as the dealer relationship is well established, surgical masks are now sold without worry.” MLM thinking is no longer appropriate, because only by taking the brand route can companies have vitality, only brands can become bigger and stronger, and only brands can gain the largest market The degree of recognition then leads to long-term profit. From Gree, the market response of BYD surgical masks is an obvious example. And those traditional mask companies that are still ignoring brands will pay for their brands.

SRSY has been devoted to the research and development of solar energy industry for 21 years, two national standard and seven industrial standard drafting units, two national patent invention gold awards, a number of industry invention patents, and cooperated with CCTV to build a solar brand strategy. Obtain No.1 achievement in solar street light industry now.

The brand of this mask company is limited because, in the highly homogeneous competition, manufacturers do not directly contact consumers, but pass through layers of distributors, which causes mask brand power to disappear and the company has no intention to build a brand moat.

In contrast, the solar lamp industry is just the same. We know that first-class companies write standards and make brands; second-tier companies do production and processing; third-tier companies just do services. In these enterprises, most of their attributes are born out of the gulf. They pursue speculation and quickly make profits. They have no intention or ability to invest resources and efforts in brand building and technology research and development.

As for when they leave the field, it is unknown, they can only say “they have been soaking in warm water for too long”, because we know very well that no matter how good the platform, how gorgeous the wording, how fun the game rules, success Even if it fails, everything will eventually be paid by consumers. Based on this principle, SRS proposed that we must be loyal to our customers, so we have the saying that “we are starting from users, 21 years, we just commit to produce a perfect solar street light that everyone can afford.”

The straw that crushed the mask industry: quality

It is not only large-scale manufacturing companies that see the business opportunities of surgical masks, but also more small businesses and individuals who want to take a piece of it. Business-minded people will consider setting up a mask factory. The policy encourages the approval of related certificates to be very convenient, and it can be done by buying raw materials and machinery. There are not a few small workshop-type mask manufacturers, but their daily production capacity is only tens of thousands. This is the same as the lamp industry market. Looking back at the Chinese lamp city, there are not a few small workshops and group companies, and there are only a handful of products with brand strength. Breaking down into the solar industry, how many brands can you name?

Survival. Even though everyone is willing to drink this bowl of chicken soup, few people can adhere to it. SRS has more than 20 years of technological precipitation in the industry, bringing good reputation with advanced technology + good materials + good craftsmanship, full of social responsibility, creating value for society, and benefiting humanity.

Finally, let’s look around the lighting industry market again, we just want to be frank: you missed Philips, Osram 20 years ago, you missed Oppu and NVC ten years ago, now the photovoltaic era is coming, please do n’t miss SRS Solar Street Light: Save Money-Durable-Good Installation!

“Good mask, made by Gree” —- “Good solar street light, SRS”

Why do some cars only light up one rear fog lamp

I wonder if the car owners have paid attention to the rear fog lights of their cars, are they one or two? I believe that many people’s first reaction is affirmative, of course there are two! In fact, there are indeed two rear fog lights when they are not in use. However, when the rear fog lights of some cars are turned on, only one lights up. What is going on? Is it broken, or is it reduced?

The answer is neither! Car rear fog lamps must be installed according to national regulations, but there is no requirement to install one or two. Therefore, from the legal point of view, only one rear fog lamp is in compliance with the regulations.

Everyone knows that fog lamp for car is mainly turned on during rainy and foggy weather, and the purpose of fog lights is to remind the car in front of the car to avoid rear-end collisions.

The rear fog lights, like the rear width lights and brake lights, are red, but the rear fog lights have stronger penetrating power, which is more dazzling. But the rear fog lights are very close to the rear brake lights. Some models have high-position brake lights, so if there are two, if your fog lights are on, people think you are lighting the brake lights, which may cause misjudgment.

Therefore, in order to clearly distinguish the rear fog lights, so as not to be mistakenly identified as brake lights by the car behind, the design idea of ​​”install only one” is adopted. At least we usually see that the lights on the bottom of the car are in pairs. So if a fog lamp is turned on alone, it is easier to alert the car behind. However, the design of the two rear fog lamps is not without, but basically models with two fog lamps will separate the brake lamps and the fog lamps far away, making it easy to distinguish.

Therefore, if your car has only one rear fog lamp, don’t think too much about it, thinking that the car factory has reduced the equipment, which will affect safety. In fact, only one fog lamp is not a big problem. On the contrary, there may be a little more benefit.

LED Floodlights – A Multipurpose Lighting Solution

LED Floodlights are currently very popular for being an extremely competent, durable, and affordable lighting option. These lights are capable of fulfilling your indoor and outdoor lighting needs. LED Flood lights have the capacity to illuminate a residence, lawn, street and even an enormous sports field. Flood lamps will provide you with the best possible brightness and luminosity as compared to the ordinary halogen bulbs.

LED Flood lamp includes light-emitting diodes that allow maximum coverage with minimal power consumption. This is one of the major reasons why a people prefer LED Flood lamps as compared to other lighting options that are available in the market. Although these lights are very expensive than mercury or halogen bulbs, they do provide several benefits which cannot be ignored. Depending upon your specific indoor/outdoor lighting needs, these lights can be purchased in low/high voltage with or without various technical enhancements.

Since the time that LED lights were first introduced in the early 1960’s, their features have been updated several times. Today, you can find LED Flood bulbs in a number of shapes, sizes, colors and designs respectively. Various commercial landscaping projects get maximum usage out of LED Floodlights by installing them even in the most difficult areas. This feature helps in saving a considerable amount of electricity and environmental preservation, all at the same time. LED Flood lamps can also be used as a temporary lighting solution for special occasions like social events, birthday parties, anniversaries, camping, festive celebrations, etc.

Thus, if you wish to use them in any indoor or outdoor setting, you can save yourself from incurring unwanted expenses of hiring a professional technician. You can easily trace various Do-It-Yourself articles on LED Flood Lamp Installations on the Internet.

What is the difference between fog lights and low beam lights?

Why can’t we use fog lights as daily lights? The difference between fog lights and low beam lights is the angle of illumination, brightness, light source penetration, etc. In these aspects, fog lights are stronger than low beam lights.

The fog lamp for car does not have a hood, and the power of the bulb is high, and the light source has strong penetrability, so it will be particularly dazzling. In order to allow the light to penetrate rain and fog in rain and fog, the fog light source has strong penetrability, and the front fog lamp has no hood structure. The power of the rear fog lamp bulb is relatively large, and the penetrating power is also strong. Don’t turn on the rear fog lights when visibility is high. They are too dazzling and will affect the drivers of vehicles behind them.

The function of the dipped beam is to illuminate a certain distance in front of the vehicle. Its illumination angle is lower than the horizontal line, and the power of the bulb is not large, so it will not cause interference to the drivers of other vehicles. The power of the low beam is not as high as that of the fog lamp, and the illumination angle is not high, so it can clearly illuminate the road in front of the car without causing interference to other drivers.

However, in a foggy day, the low-penetration low-beam lamp is very difficult. At this time, the fog lamp must be used to make up for the defect that the low-beam lamp cannot penetrate heavy rain and dense fog. Therefore, the fog lamp can only be used as an emergency lighting tool under bad weather conditions, and cannot be used as a daily lighting lamp.

How to install LED light bulbs safely

As a necessary lighting appliance in life, led bulbs often need to be replaced. As a life expert, how can you not install bulbs? Now let’s talk about how to install led bulbs. Those who don’t know how to install bulbs themselves should learn quickly.

1. Prepare a led light bulb, the power is 40W for general household use, and confirm the connection method of the light bulb at home. Commonly used are screw and socket. The difference between the screw socket and the socket of the bulb is because the humidity in some places in China is too high, the screw socket is easy to rust and the bulb cannot be screwed off. This is not easy for sockets. Therefore, the use of southern socket bulbs should be more popular.

2. Although the installation of light bulbs is not a major project, the installation process should not be careless, otherwise safety problems are prone to occur. When installing the light bulb, it is absolutely not allowed to “fold a big chair over a small chair”, and the consequences will be disastrous once it falls. It is recommended to use a herringbone ladder, which is safer, and it is better to have a helper to stabilize the ladder to prevent accidents.

3. Find the entry switch at home and open the switch. Because the light bulb switch only turns off one line of electricity (generally 2 sets of electricity at home, live wire and neutral wire), although the light bulb does not light up, it is very likely to be charged. Pulling off the main switch is to ensure safety.

4. There is a red wire on the lamp holder as the live wire and a blue wire as the neutral wire. When connecting the lamp holder, use a test pen to check whether the two wires have electricity. After confirming that there is no electricity, connect the live wire and the lamp holder wire. , And wrap the insulating cloth, then connect the neutral wire to the other wire of the lamp cap, and wrap the insulating cloth.

5. Climb up the ladder to change the bulb, turn on the flashlight, hold the bulb holder with one hand, and the broken bulb with the other, apply a counterclockwise force with the left hand and clockwise with the right hand in advance, the attention can be tentative, because some bulbs Over time, it may be broken if you use strong force, then slowly increase the force, and you can screw it off. Then replace it with a new light bulb and tighten it.

6. Due to energy conservation and environmental protection reasons, the country has banned the sale and production of incandescent lamps. However, this experience sharing does not affect his use, because the connection of incandescent lamps and energy-saving lamps is the same, but it should be noted that do not hold the lamp tube when installing the energy-saving lamp, the lamp tube is easy to break, other steps are the same as incandescent The installation of the lamp is the same.

Precautions for installing the led light bulb

1. Insulation should be done well in humid environment, such as bathroom and kitchen, if insulation is not done well, it is easy to short circuit.

2. The light bulb is made of glass. When installing the hanger, an iron expansion bolt (iron expansion pin) must be used. Do not punch a hole first, and then drive a wooden wedge to tighten the screw. This method is only suitable for The horizontal fixing of the wall is not suitable for the top surface. It is also not recommended to use plastic expansion tubes, because plastic expansion tubes will deteriorate over time.

3. Prepare some No. 6 screw nuts in advance, because you will encounter such a situation when installing the lights: when installing the chassis, because the original screw nut is sealed at one end, it can’t be screwed to a certain extent. In this case, you can screw a No. 6 screw first and increase the force, and then screw the original screw, which is beautiful and prevents the chassis from not being able to completely match the top surface.

Reasons for dimming LED light bulbs

Guangli introduces the reasons for the dimming of LED light bulb.

1. The quality of LED products:

1. The LED chip used is of poor physique and the brightness decays quickly.

2. 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 and the chip failure.

2. One or some LEDs are burnt out.

Many LED lights are grouped in parallel. For example, 60 LED lights are divided into 3 groups, and each group is 20 in series. When a certain LED in a group burns out, all the LEDs in the group are not bright, but the LED lights in other groups are still normal Light up, due to the lack of a certain group of LED lights, the entire LED lights will be significantly dimmed. The principle is similar to the figure below. The figure below shows a parallel connection of 4 LEDs as a group. Burning one group has almost no effect on the other groups.

It is best to disassemble the lampshade of the LED lamp and check if there is any LED lamp bead that is not bright. . In this case, you need to replace the LED, but most people will not have ready-made lighting LED lamp beads, and it is very troublesome to buy. The lamp beads are not very expensive, but the shipping fee is expensive! If you only burn one or two, you can use about 150Ω If a group of more than 20 LED lamp beads are connected in series, it can be directly short-circuited after a certain LED is burned, which has almost no effect.

3. The heat dissipation problem of the product causes,

There are bricks in the production process, and the LED chip heat dissipation is not good. It is derived from the PIN pin, which causes the LED chip temperature to be too high and the chip attenuation increases. LED lighting has been solving the heat dissipation problem since its birth. This is why the product heat dissipation components and shells are used The main original solid of the aluminum village. Solving the problem of soil heat dissipation is the most important way to improve the life of the LED and reduce the light decay, and the effect is the most obvious.

Fourth, the chip

The chip is the luminous body of the LED lamp, so when the chip is damaged, the brightness of the LED lamp will be weakened, which is what we call dimming, which will seriously cause the entire LED lamp to not light up. Minghong uses the original imported COB high-brightness chip to reduce the light decay from the source, and the light is uniform and comfortable, more transparent and bright, with a long service life and a three-year warranty.

Fifth, the capacitance of the capacitive resistance step-down circuit has deteriorated.

The capacitive resistance pressure circuit is composed of a capacitor and a resistor in parallel. The capacitive reactance of the capacitor Xc=1/2πfC, where π is a constant of about 3.14, f is the frequency of alternating current, the frequency of 220v alternating current is 50HZ, and C is the capacity of the capacitor. When the capacitance value of the capacitor becomes smaller, the capacitive reactance becomes larger, which causes the total impedance of the capacitive resistance circuit to become larger, and thus the voltage drop becomes larger, which causes the voltage of the rear-end LED to be lower, which makes the LED dim.

Summary: There are many reasons for the light decay of LED products, and the most critical one is the heat problem. Although many manufacturers do not pay special attention to the problem of heat dissipation in secondary products, the degree of light decay will be more important than those of secondary LED products under long-term use. The heat dissipation of LED products is higher. The thermal resistance of the LED chip itself, the influence of silver glue, the heat dissipation effect of the substrate, and the glue and gold wire are also related to light decay.
