1. What is the reason why road Lights flash and flash

When you walk on the road at night, sometimes you find that the street lights on the road flash and flash. Usually, human eyes can perceive the light of 70 Hz. If it is lower than 70Hz, the human eye will feel flickering.It will stimulate the eyes, and it will also affect the lighting effect. This is generally LED street lights. The reason why LED street lights flash may be the following:

1. Drive power problem

The driver of LED street lights generally uses a constant current power supply. The basic working mode of the constant current power supply is to continuously adjust the output voltage to ensure that the current is constant when the internal resistance change of LED lamp beads, but this adjustment has a certain limit. There is a certain limit.The Hengli power supply has a range of output voltage. Once the breakthroughs are made, the power supply will enter the protection state. The expression form is that the lamp starts to flash.

2. LED lamp bead problem

LED lamp beads and LED drivers are not matched with flashing phenomena. Normal single-footed 1W lamp beads bear the current of 80-300mA and a voltage of 3.0-3.4V.In the phenomenon, the current is too high, and the lamp beads cannot bear it.

3. The lamp is broken

The phenomenon of frequent lighting in outdoor lamps may be that the lamp is not done well, which causes the water to water. The damage to the damage of the lamp and the driving power supply will cause the flash and need to be repaired in time.

2. LED street light flashing failure solution

The LED street lights have been flickering. The maintenance personnel must first check whether the problem where the problem is driven or LED lamp beads. You can check the faulty parts by replacing the drive power and lamp beads separately.Essence

Sometimes there will still be a flickering failure after the street light is turned off. This must be considered whether it is the problem of the line. It may be a problem with the zero line controlled by the switch. This needs to be dealt with in time to avoid accidents.If you find a problem, it is likely that the LED street light itself generates a self -sensing current. The connection of the coil and the electric lamp with relays can solve the problem with relay.

Third, the street lights are broken to what department to respond to

What should I do if I see the street lights broken?When the street lights are flashing or not bright, ordinary citizens should feedback the situation to the relevant departments, so what part of them should be reflected?This should be determined based on the nature of the street light:

The street light management in my country is divided into two types. One is the social street lights that occupy most of the ratio. This street light is broken. It should be reported to the municipal department or the city's power bureau street light management office where the city's power bureau is located.If it is a street lamp purchased and installed by communities, communities, and villages, it is usually applied for maintenance to the property and village committee.There is also a landscape landscape of the scenic area or Park. If this street light is broken, you can go to the tourist center of the Park or scenic spot to reflect the problem.

1. What is the Solar landscape lamp

Solar Landscape lights use Solar power generation as electrical energy supply, providing night road lighting, high -light lighting light source design, light control over time control, with high brightness, easy installation, stable work, no cables, no conventional energy, life spanThe advantages such as longness belong to the green energy products that are strongly advocated in today's society.It is mainly used in urban roads, community roads, industrial parks, parks, roofs, night scene lighting and landscape lighting in places such as green belts, squares, pedestrian streets, fitness and leisure squares.

Second, Solar Landscape light work principle

The Solar Landscape light is to convert solar energy into electrical energy to achieve lighting. The top part of the landscape lamp is a Solar panel, which is also known as photovoltaic components.Convert solar energy into electrical energy in the battery,At night, the battery pack provides electricity to power the LED light source to achieve the lighting function.becauseSolar Landscape lightPower generation through solar energy, so there is no cable, no leakage and other accidents occur.The DC controller can ensure that the battery pack is not damaged due to over -charging or excessive release. At the same time, it has functions such as light control, time control, temperature compensation and lightning protection, and anti -polar protection.

1. What is Outdoor light box advertisement

What is the Outdoor light box advertisement?Light box advertisements are also known as "light box posters" or "night promotional painting".For Outdoor light box advertising, its application places are distributed on both sides of the road and the streets, as well as public places such as shadow (drama), exhibition (sales), commercial downtown, stations, airports, docks, parks and other public places.It is called "semi -permanent" street art.The new flexible light box changes the traditional light box during the daytime, and there is no shortage of images and text -shaped, with its realistic images.The rich glyphs show the unique decorative effect with gorgeous colors and strong texture regardless of day and night.The production technology and materials and processes of flexible light boxes can not only make the giant light box covering the entire wall and the building, but also make it into physical models.Flame retardant.It is widely used in banks, supermarkets, fast food restaurants, gas stations, etc., and has become a new form of facade decoration of the store.

two,Outdoor light box advertisementWhat are the characteristics

What are the advantages of Outdoor light box advertising?Due to the huge display screen and fixed display venue, the following characteristics:

1. Wide content

In terms of public transportation, transportation, safety, welfare, savings, insurance, taxation, etc.; in terms of commercial products, enterprises, tourism, services, etc., in terms of culture, education, and art in culture and education, they can be widely extensive in terms of culture, education, and art.Play.

2. Great picture

Many graphic advertising media are conveyed indoors or small -scale, and the area is small.The Outdoor light box advertisement shows the advertisement content in the form of the door, the notice (publicity) column, and the rod light box.It is larger than other flat advertising illustrations and fonts, which is very eye -catching.

3. Together

There are many forms of display, with both text and color functions. From product trademarks, names, physical photos, color, color, corporate intention to culture, economy, customs, beliefs, and concepts.By conceiving and unique ideas, we must grasp the "ring" of inducing consumers to buy the desire to buy, and to achieve the purpose of advertising with the heterogeneity conveyed by visual communication.

4. Strong vision

The function of Outdoor light box advertising is to convey information to Outdoor people and long -distance people through two forms: natural light (day) and auxiliary light (night).The endowment effect of advertising works is strong, which is beneficial to the fast pace, efficiency, and rushing people in modern society.

5. Fixedness

No matter what form of Outdoor light box advertisements, there is a requirement of a certain range and location.As a semi -permanent display device, its basic structure is more complicated than other advertising forms.Including frameworks, compound materials, pattern printing layers, windproof, rainproof and snow -proof structure, and lighting facilities for lighting at night, the cost of copying its single piece is higher than other types of advertisements.

three,Outdoor light box advertisementComposition

1. Framework

The main components of large light boxes are steel and plastic structures. The base and borders are welded with steel or stainless steel structures. The outer cover of the pattern is glass plate, organic glass plate, light box cloth, etc.The main components of small door heads, rods, and suspension light boxes are steel or injection frames. Most of the outer masks of the pattern use glass, organic glass or transparent plastic board.

2. Carrier

The printing carrier of the light box can use synthetic paper, inkjet film, self -viscous glue film, light box canvas and other materials according to its structure and production process.

3.

The auxiliary light (commonly known as light) of the light box is based on the structure of the pattern picture, and the printing materials, the thickness of the ink layer, and the pattern surface are used for lighting design.In the past, ordinary fluorescent lamps were mostly used. With the application of new lamps, the auxiliary light of the light box also developed from a single light to multiple types of light.The resulting picture quality and uniformity and softness have been greatly improved.

1. Strong light probe Lights do not light up for maintenance method

Detective Lights are a very easy -to -use Tool when traveling outdoors. It can be manipulated or worn on the head to provide long -range lighting effects. However, sometimes due to the quality of the detection Lights or improper use, the probation Lights fail.In the case, how can I repair the strong light probe?

The structure of the probe lamp is relatively simple, including a switch, the battery placement position and the lamp head of the back of the rear. During maintenance, we can use a small cross screw knife to check the fault one by one and repair:

1. First of all, see if it is a switch or where the contact is poor. If the switch is pressed repeatedly, there is no shiny trace of the lamp beads, which means that it is not a problem of poor contact.

2. Open the battery placement in the back, change the battery, see if it is the problem of the battery or there is no charging.

3. After excluding the above reasons, the rest is the failure caused by the internal line. This needs to be removed and repaired. The specific method is to hold the light head in the right hand, rotate the lamp head in the counterThe connection point of the circuit and the circuit board of the light line and the light head, if it is intact, exclude the possibility of some lines of the lamp head; if there is a problem, connect the line, and the specific method isCome down, expose a long section of metal wire, and wrap the metal wire to the disconnected battery base metal piece, and tighten it.

4. Then put the lamp head back, insert the cross screw knife to the place where the lamp head and the rear part are connected, hold the other end of the screw, rotate the cross screw knife against the right hand, you can twist the screws.Part of the stuck place separate, and then use a screwdriver to remove the two screws of the battery installation position. See if the line between the metal sheet of the battery base and the lamp head is broken. If it is broken, the maintenance method is the same as the step 3.

Tips:When disassembling the battery base, gently separate to prevent too much force from the wire head and the wire between the battery directly. After the line is connected, do not rush to load it back. Try the fault to eliminate it.

2. What are the precautions for the use of the viewing light?

The use of the exploration Lights is limited. In order to facilitate use and avoid failure, we must pay attention to maintaining and maintained strong light probe Lights during use:

1. In the case of long -term use, it must be charged once every three months to keep the internal current Running.

2. Although the probe light has certain protection performance, after all, it is an electronic product. Usually use it away from the water source to prevent short circuit circuit.

3. Do not frequently press the switch when using the probe light to prevent the lamp beads from being broken.

4. Do not wait until the electricity is completed after the electricity is used to avoid loss.
