What is the height of the street light manhole from the ground

The height of the street lamp manhole from the ground is determined according to the actual situation, generally speaking, the ground clearance of the street lamp manhole should meet the following considerations:

First of all, the height of the streetlight manhole should be convenient for service personnel to carry out access and maintenance work. In general, the height of the streetlight manhole should allow maintenance personnel to easily enter and exit to carry out the necessary repair work. This can improve the efficiency of maintenance and reduce maintenance time.

Secondly, the height of the street lamp manhole should be able to ensure the safety of maintenance personnel. Maintenance personnel need to stand on the manhole to operate when carrying out maintenance work, so the height of the street lamp manhole should be able to ensure the stability and safety of maintenance personnel. Generally speaking, the height of the street lamp manhole should not be less than meters to ensure the safety of maintenance personnel.

In addition, the height of the street lamp manhole also needs to take into account the installation height of the street lamp and the surrounding environment. If the installation height of the street light is high, then the height of the street light manhole should also be adjusted accordingly so that the maintenance personnel can easily carry out the maintenance work. At the same time, if there are some obstacles in the surrounding environment, such as trees, buildings, etc., you also need to consider the impact of these factors on the height of the street lamp manhole.

To sum up, the height of the street lamp manhole from the ground is determined according to the actual situation, and the operation and safety of maintenance personnel, the installation height of the street lamp, and the surrounding environment need to be considered. Generally speaking, the height of the street lamp manhole should not be less than meters, but the specific height needs to be adjusted according to the actual situation.

1. The installation height of the lamps and lanterns must be the same as the installation height of the lamps and lanterns on the same street (the height from the luminous center to the ground). Small bend light: One meter light, 5-6 meters, ordinary street, long arm lights and chandeliers, meters, fast lane arc lights are not less than 8 meters, slow lane arc lights are not less than meters.

2. The special lamp type is installed according to the design requirements, and the height of the lamp is equivalent to the width of the road to be illuminated. When lighting only on one side h l When lighting on both sides h l 2 where, h: luminaire installation height (m) l: road width (m).

Thank you for adopting, please.

Generally, the roads in residential areas and rural areas are not too wide, and it is enough to use 5-6 meters of street light poles, and if it is a township road, it is recommended to use 7-8 meters of street light poles.

Mainly depends on the installation location, different places need different heights, such as both sides of the road, basketball courts, overpasses, etc., each place needs different heights street lights.

Mainly look at the ** installation, in the countryside, generally 6 meters 30 watts are enough, the light time is 5 hours, 1 hour in the morning, 3 days on a rainy day!

What is the height of the road street lights is exclusively provided by Haiyan Lighting.

1.The height of road street lights has always been a problem that plagues procurement customers, too low street lights can not achieve the lighting effect, and large vehicles will touch the lamp head and lamp arm when passing by, resulting in unnecessary loss of personnel and property.

2.Using too high street lights, not only the cost of street lamp poles will rise, the power of the light source will also increase, the power will increase, the cost of the light source will also rise, and the installation of a crane is also needed, even the cost of installation will rise, so it is particularly important to choose the height of the street lamp at the right height.

3.When customers purchase street lights, they should communicate with the customer service of Haiyan Lighting about the location and function of use, so that the customer can configure the appropriate height, so that it will not cause waste of resources and fail to achieve the purpose of lighting. For the specific height, please refer to the --- street lamp height standard on the official website of the street lamp.

What is the height of the road street lights.

This should be determined according to the actual situation, the general urban road is a little narrower 6 7 meters is enough, and the road is wider generally 9 12 meters. If used in the square, the airport will generally choose the high pole lamp for lighting, the common specifications of the high pole lamp are 20 meters, 25 meters, 30 meters, 35 meters, 40 meters can be selected according to the actual situation, but the high pole lamp more than 35 meters to find a special manufacturer to produce, the general small factory production of more than 35 meters of high pole lamp safety factor can not reach the potential safety hazards.

The spacing of street lights is determined according to the nature of the road, such as factory roads, rural roads, urban roads, and the power of street lights is 30W, 60W, 120W, 150W. The width of the road surface, the height of the street lamp pole determines what the street light spacing is, in general, the street light spacing of urban roads is between 25 meters and 50 meters.

If it is a small street lamp such as landscape lights, garden lights, etc., in the case that the light source is not very bright, the spacing can be slightly shortened, and the interval can be about 20 meters.

The brightness is low, expensive, LED fluorescent lamps to buy more than 200 to 300 yuan, and ordinary fluorescent lamps even brackets only cost 20 yuan, and then ten or eight years, maybe the brightness and ** should be better, LED is now used in the display and decorative lighting with more, I am making LED products, if you call me LED lighting products at home, I definitely don't, or the traditional fluorescent lamp, energy-saving lamps are easy to use, economical, and high brightness.

If you say that LED is used in street lights on the road, it is strange not to crash, the weakness of LED is that the range is short, the light is not far, when you look at it closely, you will feel very bright, in fact, it is not. The high pole lights on both sides of the road are generally 5,6 meters high, LED shines on the road surface is already no light, if used in parks and paths, the brightness requirements are not high, the installation of street lights is not very high, it is best to be solar, electricity costs are saved, and you can light it for two or three days when there is no electricity. Or it is a combination of traditional light source and LED method, using traditional light source lighting in the first half of the night, and LED light source lighting in the second half of the night when there are few people.

However, I personally think that there are still no traditional energy-saving lamps for street lamps, halide lamps, nano lamps are economical and easy to use, now the quality of the LED industry is too bad, LED is said to be able to use up to 100,000 hours, if it is made into a lamp, it is not the case with other electronic components, the life of other electronic components is generally tens of thousands of hours, and now many manufacturers are using second-hand electronic components (especially the manufacturers of the ancient town), not to mention the lifespan, plus the environmental impact of outdoor use, *** LED lighting products may have a life of 4-50,000 hours, and 5,000 hours of poor quality are not, which is also the reason why the current LED industry is very different.

The installation distance to the ground and the range are:

500 meters, meters, 50 meters.

Principles of factory road lighting design:

A reference is to refer to and implement the People's Republic of China industry standard CJJ45-91 urban road lighting design standard. This is because the standard reflects the basic requirements for general road lighting and because the company has a close connection with the city. Historically, many cities in China have developed on the basis of one or several large industrial enterprises; In reality, many large corporations are also an important part of the city.

Why only for reference, most of the roads in the factory area are mixed with motor vehicles and pedestrians, and the vehicle speed, flow and traffic volume are far less than the general urban roads. If the factory road lighting is required to fully implement the 5 urban road lighting design standard 6, it is not realistic from the economic aspect, and it is not necessary to consider the function aspect.

One is to adhere to the principle of functionality. The basic purpose of the road lighting in the factory area is to provide a certain bright visual environment for automobile transportation, pedestrians and plant security at night, and eliminate various dangerous situations that may be brought by darkness. Therefore, the evaluation of visual function should be the main focus.

Among them, the average brightness (or illuminance) is used as the key index.

Appropriate consideration, that is, within the scope of economic reasonableness, through the optimization of engineering design, taking into account the indicators of visual function 0 and visual comfort 0, and also taking into account the requirements of decorative performance. Specifically, in the evaluation index, the requirements of brightness (or illumination) uniformity, glare limitation and induction are taken into accountIn the shape selection of lamps and lanterns, the requirements of aesthetics are taken into accountConsidering the night landscape of the enterprise, lighting can also be appropriately taken into account in a few landmark road sections.

In general, the installation distance, ground clearance and range of street lamps in the factory area are: 500 meters, meters, and 50 meters.

At the same time, the design of street lighting on the roads in the factory area should be considered comprehensively in combination with the road grade.

Designers should follow the "Urban Road Lighting Design Standard" CJJ45-91 when designing road lighting.

Lamps are usually half-cut light type, and the height of street light poles is from meters to 9 meters. Lighting fixtures are usually 250W or 400W metal halide lamps (with compensation required).

Street lights with pole heights of between meters and 6 meters are usually used for pedestrian-only roads, and street lights with pole heights of 9 meters are usually used for roads that are only used for vehicles.

Most of the road lighting fixtures in the factory production area use 6-meter light poles, and the Luding spacing is not easy to be greater than 45 meters at this time.

Distance 30 50 meters Height 5 meters.

High-pressure sodium lamps.

There are many specifications, which can be roughly distinguished by the width of the road, and the street lights of the main road (more than eight lanes in both directions) are more than 12m high;The secondary trunk road lights are more than 9m high;Alleys are more than 4m;The intersection has a high pole light of 16m or more.

According to the width of the road, different road widths and different light pole heights, some road sections, but also consider whether there is a green belt in the middle.

Question 1:

Solution 1: If there is no threading well, then the light will not be too high, you can put the light pole down and lead out the cable through the broken wiring.

Solution 2: If it is a light pole of more than 8 meters, there will be a wiring well, then the cable can be pumped back into the wiring well, make a joint in the wiring well and thread a small wire into the light pole.

Problem 2: At least one meter of margin should be left for wiring of embedded cables.

1.After connecting it on the outside (make an intermediate joint), thread it in.

2.At least 50cm, it is most convenient to crimp copper pipes on the ground.

A copper-core cable can be used as a grounding wire to connect the lamp pole and the grounding grid, but because the cable is sheath-insulation, it cannot be used as a grounding body and grounding grid to reduce grounding resistance.

The lighting height of urban roads is generally 9-12 meters, and the lighting of rural roads is about 5-6 meters.
