1. What is a ground lamp

The land buried lamps are widely used in the field of technology lighting in my country. Because it is buried on the ground for people's lighting, it is named for land buried lamps. Voltage: 12V-220V, power: 1-36W, protection level: IP6.5, control method: Internal control, external control, DMX512 control can be available; there are two types: ordinary light sources and LED light sources in light sources. The high -power LED light source and small power LED light source are generally monochrome. , LED light sources have seven colors, and the colors are more colorful.Land buried lamps are widely used in squares, restaurants, private villas, gardens, conference rooms, exhibition halls, community environment beautification, stage bars, shopping malls, parking sculptures, tourist attractions and other places.

2. How to install the LED floor lamp

1, Preparation before installation

1) Prepare parts and need tools.

2) The power must be cut off before installation.

3) First dig the embedded hole according to the outer diameter size of the embedded parts, and then fix it with concrete.

4)The main line diameter must be greater than the line diameter of the lamp.

2, installation process

1) After the embedded parts are fixed, connect the input wire of the buried lamp with the external wires, and the phase lines, zero lines, and ground wires are connected and waterproof.

2) Use screws to fix the lamp component with the embedded parts.

3) Use the screw to fix the noodles on the lamp component.

4) After determining that the above operation is correct, connect the power.

3. installation of buried lamps

1. Before the LED buried Lights are installed, the power must be cut off.This is the first step in the installation of all electrical equipment and the basis for safety operations.

2. Before the LED buried lamp installation, various parts of the lamps should be sorted out.The LED buried lamp is a special landscape LED lamps buried in the ground. Once it is installed, it is troublesome to reinstall it.So you should be ready before installation.

3. Before the LED buried Lights are installed, the shape of the embedded parts should be connected to the size of the embedded parts, and then the embedded parts are fixed with concrete.The embedded parts played the role of the main body and the soil of the LED ground lamp, which can ensure the service life of the LED ground buried lamp.

4. Before the LED buried Lights are installed, a wiring device with an IP67 or IP68 should be used to connect the external power input and the power cord connection of the lamp.In addition, the power cord of LED buried Lights is required to use VDE -certified waterproof power lines to ensure the service life of LED ground buried lamps.

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. How far can the high -power Telescope be seen

This is the first time I like to ask a friend who is in contact with the Telescope.The answer is infinite.In fact, the true intention of this question should be the ability to distinguish the Telescope.This involves three factors:1, Observe the environment, including light intensity and direction, contrast, atmospheric stability and transparency, etc.2The quality of the Telescope itself, including specifications, categories, accuracy, etc.3The vision condition after the observer himself, and the degree of use of Telescope proficiently.this3This is basically uncertain. If you only consider the identification ability of the Telescope itself, generally speaking, a Telescope with a larger diameter and a higher multiples is higher.PorroPrism Telescope ratioroofThe prism Telescope has a higher resolution, and the coated mirror has a higher resolution.

It is important to emphasize that the multiple of the Telescope is only one of the many associated factors that affect the resolution. It is not advisable to blindly pursue a large multiple.

Second, the higher the high -power Telescope multiples, the better, the better?

Many people always think that the higher the multiples, the better, and some manufacturers also attract consumers with false high multiple. In fact, the reasonable multiples of a Telescope are related to the caliber and observation method of the Telescope: large caliber, multiples can be higher appropriately higher than higher, which can be appropriately higher than higher.The fixed observation with the triangle can be higher than the handheld observation.

If you choose the two -Tube Telescope with observations,7-10Between times enough, do not exceed the highest12More than, the higher the multiple, the smaller and darker the observation field, and the observation effect will decrease, especially the jitter brought by the high multiplier has greatly increased, making the observation scene unable to stabilize, and it is difficult to observe normally.

The multiple of the Telescope is theoretically inversely proportional to the visual field of the Telescope. The higher the multiple, the smaller the view.Therefore, the multiples of the Telescope are not too large.50mmThe diameter binocular Telescope, if it is here20The double is basically the limit. If the multiple is large, the field of vision is too small.It is basically impossible.

Although there are many Telescopes of the United States and Russia's equipment forces in the world, most of them are6-10Mainly, the Telescope produced by some world -famous brands is also as many as the medium rate. This is because a clear and stable imaging is the most important.

At present, the top Telescope in the world is generally adopted42mmcaliber,8-10The multiplier rate is OK.

So as a Telescope for our daily Outdoor use, it is recommended to choose7-10Times.Exceed10Try not to choose as much as possible.If it exceeds10It is recommended to use the triangle.

Third, Telescope common sense

1. Elimination multiple (angle rate):For example, 10 * 50 Telescope, 10 is a multiples. It is an enlarged corner that enlarges people to see the objects, making you feel that it is close to the object from the sense.Okay, too, the jitter and heartbeat of the hand, the ups and downs of the heartbeat, and the air convection at the same time, so that the image of the object you observe has a floating and unstable feeling, so it is generally not more than 20 times that it is best to be about 10 times.At present, some illegal actors can tell the general Telescope as tens of times or even hundreds of times in order to cater to some customers' pursuit of high multiplication. In fact, as long as they are purchased, they can identify the external goals.In addition, many customers often care about how far the Telescope can see.This view is actually uncertain.The multiple of a Telescope does not indicate how far it can see.Human's naked eye can see endless far, not to mention Telescope.To be precise, the magnification is only how many times the scene is brought closer on the basis of human eye under the condition of visibility.

2. object mirror (inlet hole diameter):For example, 10 * 50,50 is 50mm in the inlet pores.The larger the aperture, the bigger the light.The higher the clarity, the greater the aperture and the larger the volume weight, which not only increases production costs, but also is not convenient to carry.In order to increase the light transmission of light, the observed objects are brighter and clear, and the color is realistic. The coating process is basically used in the production process.From the appearance, it also plays a decorative role. Generally, it is red film and Ranla, especially the red film is loved by consumers.However, the coating Telescope (red film) still belongs to the Telescope used during the day, not what people say: "Far infrared night vision instrument".Can't use it.The price is also more than thousands of yuan, and it is not applied by ordinary customers.

3. Style (structure):It can be divided into two types: Paul and straight.Paul style Telescope is a traditional structural form.It is imaged through prism, with clear images and generous styles.However, due to the prism group, the physical tax is large.Fortunately, the development capabilities manufacturers have developed a small Paul new product with a small size and light weight.Another style is currently a popular straight Telescope.Its biggest advantage is that it is small in size, simple structure, easy to carry, and also reduces production costs. The price makes it easier for consumers to accept.

4, appearance: In addition to the coating of the objective mirror, the foreskin also makes the Telescope form a different grade and style. The foreskin is generally divided into two categories.One is an earlier artificial leather foreskin, and the other is the rubber -plastic (glue) foreskin that has appeared in recent years. The rubber and plastic foreskin not only has a good texture, but also has different colors and patterns.Provide a wider choice for consumers.

5. Quality:A good Telescope not only looks at the appearance, but also the internal quality. The Telescope produced by regular manufacturers uses rigorously tested optical glass, and it is tested after assembly. The image is clear and the structure is tight.At present, there are many inferior Telescopes on the market.Some small manufacturers use some unqualified optical glass.Even assembly of ordinary glass or resin lenses.The product has not undergone rigorous debugging and is a fake product. It attracts customers at a low price and causes customers to be violated.Therefore, when choosing, don't just look at the price, you should pay attention to the inherent quality of the product.

Can fish intestines be buried directly?

1. It can be buried directly, but there is a prerequisite. If it is planting plants and buried the fish intestines into the soil.If it is a potted plant, then if the fish intestines are buried directly, they must be cautious, because the Flower pot space is small and the pot soil is small. If the fish intestines are buried in the Flower pot, it is likely to occur.Plants bring nutrients, but can cause roots.Therefore, ground planting can be buried, potted plants should not be buried, or as little as possible.

2. In addition, since it is said that fish intestines Fertilizer, do not prevent more extension, fish intestine Fertilizer is not a kind of Organic fertilizer, it is just an Organic fertilizer. flowers do not need to myths.It is good. If there is no condition, there is no need to do this.

3. The effect of making Fertilizers for fish intestines is recognized. Not only fish intestines, even other animals internal organs are very helpful for flowers. Although the truth is like this, there are many problems in actual use.Essence

Buried fish intestine time

The best time for buried fish intestines is spring (February-March), or autumn (August-September); you can also choose to choose 1 month before blooming, or 10 days after spending.

Flower intestine Fertilizer is suitable for flowers

Buried fish intestines are suitable for most flowers such as rose, osmanthus, gardenia, camellia, Lingxiao, and Wisteria.

Method method of fish intestine Fertilizer

When the fish intestine Fertilizer is mixed with peel, corn Flour, rice bran, etc. when it is made, and then adds an appropriate amount of water, so that the hand holding the hand to loosen it and spread it as the standard.Also add an appropriate amount of brown sugar and bacterial fluid mixing solution to stir in the container, and finally seal it, put it in a place with good light and high temperature, and open it once a week.If the slight acid or the aroma of the wine appear, it means that it is completed, and it can be used.Note, then use it after dilution.

How to do Nutritional soil in fish intestines

1. Prepare foam boxes and soil

Prepare a foam box, and the fruits are equipped with seafood. They lay a layer of more than 5 cm at the bottom of the foam box. The fertile soil with poor fertility, or the old soil with insufficient fat.

2. Put into the fish intestines

After the soil at the bottom is paved, the thin fish intestines are paved again. It should not be too thick, about 1-2 cm.

3. Put in orange peel

Then prepare some orange peels and chop, sprinkle on the fish intestines to prevent odor.Those who have insecticides at home can also spray points.

4. Cover the soil

Continue to cover the soil on the fish intestines and orange peels. If the flower friends have collected fallen leaves, you can add a layer of fallen leaves but you must not add the flavor of the fish sausage. Finally, the soil is covered.Thick, about 7-8 cm.

5.

After the last layer of soil is covered, water the water, and then cover the foam box and put it on the balcony or the staircase mouth. During the period, you can open the lid and stir to ensure that the fat is uniform. Now it will be rotten in about 3-4 months.

1. How to store camping equipment

Camping is a kind of outdoor activities that are suitable for all ages. Many people like this activity. If you participate in Camping, you must first prepare camping equipment, but there are many camping equipment, especially "moving Camping".A major problem, so how to store camping equipment?

1. Edit list of camping equipment

Before each Camping, we must clarify a list of camping equipment. After all, each Camping location and goals are different. If you find that you do nt bring a camping equipment, it will be troublesome. In fact, the equipment list has another role.For the use of statistical equipment after each Camping, if you find that you bring excess equipment every time, you can remove it next time.

2. camping equipment classification and storage

If the camping equipment is not classified, it will be chaotic, especially when there is a lack of light sources. In the face of emergency situations, you can't find the required equipment.The principle of urgency and miscellaneous classification is classified and placed in the neighboring position when storing.

3. Remember the principle of light and lightness

Many people think that the Camping Backpack must focus on the bottom layer and make the Backpack stand stable. In fact, this concept is very wrong.From the perspective of the structure of the human body, the shoulder can be used to bear weight. If the weight is on the bottom layer of the Backpack, the gravity will pull the person behind; on the contrary, when the weight is on the upper layer of the Backpack, the weight will be pressed on the shoulder of the person, and at the same time, it will be more.Keep close to the back and avoid the trouble of constantly shifting backpacks during long travel.

4. Non -emergency supplies first place

The bottom of the Backpack, sleeping seats, Sleeping bags, warm clothing, etc. are not commonly used; then spread tents, sky curtains, etc., dont worry about it. Most of the current Camping backpacks are set up below.Emergency situations can be taken out of the bottom equipment.

5. Food should be placed on the surface layer.

Unless you can process food such as canned food, the Picnic session is always a great fun of Camping. However, when you go to the wild, it is more difficult to keep fresh ingredients.The ingredients are pressed, and the time to accelerates bad.At the same time, you can also put a survival blanket to clean up the Backpack on the top of the inner layer to strengthen the outer layer to protect the ingredients. The appearance of the Backpack will be more flat and beautiful.

6. Simple peripherals to avoid hooking foreign objects

The outer layer of the Camping Backpack is generally as small as possible, and even the water bottle is not recommended to put it, so as not to hook the plants and stones between the mountains and forests.It is recommended to put the mountain climbing stick on both sides of the Backpack to cope with the far path.

2. What tools do we use for storage and camping equipment

The storage of camping equipment is generally placed in the Camping Backpack. In addition to Camping backpacks, there are many storage artifacts to help storage camping equipment, such as::

1. Box kitchen

Not only is there a whole set of kitchen in the box, it can become a dining table in a few seconds. A box is all storage boxes, stove heads, tables, kitchenware.

2. Box tea room

The tea table is a storage box. Tea tables, tea sets, tea stoves, and teapots are all available. They do not waste a little space and are suitable for camp friends who like to drink tea.

3. Aluminum alloy box

This is a box that can support the atmosphere, and it is also the most suitable equipment for storing the atmosphere: lamps, coffee machines, exquisite cups, tableware, etc. The box can be used as an atmosphere ornament. It is also a very good operating table.

4. folding box

It is also a good thing for the atmosphere. Exquisite Camping is commonly used in storage boxes. It is mainly used for storing hard objects. It can be used with table boards. It can also be used as a table. If it is not used, you can fold it and leave a redundant space for the trunk.

5. Small Tool box

It is specially used to store small and fragmented things, such as rotating joints, extension lines, ignition, spray guns, etc., which is also very suitable for putting some needle wires and other items.

6. Insulation box

It can be used to store ingredients, vegetables, drinks and beverages that need to be cold and fresh. If possible, you can buy a foldable Insulation box.

7, tableware storage bag

It is used to store tableware such as chopsticks, spoons, knives, forks.

8. shoes and Bags

It is also very convenient to use shoe Bags to store clothes such as shirts.

9. Transparent storage package

There are transparent windows, easy to use, and are generally used to storage toiletries, makeup supplies or digital supplies.

10. Camping accessories package

Used for storage accessoriescamping equipment, such as ground nails, wind ropes, etc., although these can be placed with tents, it is recommended not to put it like this. One is to avoid breaking the Tent, and the other is to prevent it from being messy.
