How to install road lights? Precautions for road lamp installation
Road lights are lighting facilities that are set on the road to provide necessary visibility to vehicles and pedestrians at night. The installation of road street lights is mainly for the installation of middle pole lights, high pole lights, floodlights and floodlights. Generally, reasonable light distribution is required. The light source should have a long life and be maintenance-free throughout the year. Then how to install the road light? What are the precautions for installing road lights? Don't worry, BENWEI will explain it to you, let's take a look.
Road lights
How to install road lights?
1. Lamp height and lamp elevation angle
(1) Lamp height
1. The installation height of lamps and lanterns in the same street must be the same (the height of the luminous center to the ground). Small curved lights One meter light 5-6 meters ordinary street long arm lights and chandeliers 6.5-7.5 meters fast lane arc lights not less than 8 meters slow lane arc lights not less than 6.5 meters
2. The special lamp type is installed according to the design requirements, and the height of the lamp is equal to the width of the road to be illuminated. When lighting on one side only H≌L when lighting on both sides H≌L/2 where H: lamp installation height (m) L: road width (m)
(2) Elevation angle of lamps and lanterns
1. The elevation angle of the lamp is determined by the street width and the light distribution curve of the lamp. The elevation angle of each street should be the same.
2. When the lamp holder is adjustable, the center line of the light source should fall within the range of L/3-1/2 of the road width.
3. For the long arm lamp (or support arm lamp), after the lamp body is installed, the lamp holder side should be raised 100 mm higher than the pole side.
4. For special lamps, the elevation angle of the lamp should be determined according to the light distribution curve.

12. The lamp tuo and the lamp tube flange must be matched with cracks and scars, the screws must be complete, and the length of the bolt should be able to penetrate the lamp tuo flange.
13. When a lamp is suitable for bulbs of different specifications, the fixed point of the lamp socket should be adjusted to the same position as the capacity of the bulb to obtain the best light distribution curve.
14. There is no serious corrosion, cracks, scars, etc. of all kinds of iron parts. Those who have peeled off the paint should remove rust and paint or galvanize.
15. The lead wire of the lamp cap of the enclosed lamp should be protected by a heat-resistant insulating tube (asbestos tube or porcelain tube).
Three, Lipi line
1. Insulated sheathed wire should be used for vertical sheathed wire, copper core shall not be less than 1.37 mm, and aluminum core shall not be less than 1.76 mm.

3. The method of connecting the vertical line to the power supply side.
4. If the vertical leather wire is more than four meters, it should be fixed with a support in the middle, using no less than 7/1.0 insulated stranded wire, and connected to the single-cross binding method in the standard issued by the bureau.
5. When the trunk line and the vertical line are of different metals, alternate tying wires should be used as the transition joint bow. The longest bow should not exceed 100 mm.
6. The vertical leather wire should have a black tie wire at the insulating support. It is not allowed to wind it with this wire.
7. Plastic pipe should be added to the iron pipe or gray rod hole of the power cord, and the pipe length should not be less than 200 mm.
8. The volley section of the vertical line can have at most one joint, and the joint is wound around 5-7 times on both sides, and covered with rubber cloth. Different specifications cannot be butted.
9. The power cord that penetrates into the iron pipe and rod hole has no joints.
10. Standing lines are not allowed to pass between high-voltage lines.
11. The vertical line of the transformer pole close to the high-voltage lead needs 7/1.0 insulated stranded wire, and the tie wire should be wrapped around 30-50 mm after the back buckle at the connection with the main trunk line.
12. The vertical lines of street lights should be tied tightly, neatly and appropriately, and those with broken skin and bare lines should be replaced.
13. When the vertical line of the street lamp and the household connection line swing at the maximum, the distance between them shall not be less than 50 mm.
14. When the vertical wire is connected to the power supply, the bow should be tightened with pliers during construction and maintenance.
15. At the crimping screws of capacitors and ballasts, up to two thread ends can be pressed. The bending direction of the thread ends should be clockwise and pressed with flat pads.
16. The zero line of the vertical line of the street lamp is forbidden to overlap with the zero line of the user connection line to prevent the power supply from the user table when the zero line is disconnected.
17. The lighting of public toilets shall be implemented in accordance with the standard of household connection line issued by the bureau.
18. After the horizontal line and the vertical line of the long arm lamp (large carrying lamp) are tied back on the same bottle, a transition bow should be left.
Fourth, flying insurance and branch insurance
1. All street lights must be protected by fuse and installed on the live wire.
2. For lamps with ballasts and capacitors, the fuse must be installed on the outside of the ballast and electric fuse.
3. Mercury lamps of 250 watts and below, 5 amp fuse for incandescent lamps. A 250 watt sodium lamp can use a 7.5 ampere fuse. 10 Ampere fuse for 400 watt sodium lamp.
4. The incandescent chandelier should be equipped with two insurances, 10 amperes at the pole and 5 amperes at the lamp holder.
Five, long arm lamp
1. The long arm lamp hoop must wear a double female, which should be firmly fixed to the pole, and it is not allowed to rotate.
2. The lamp body should be straight and the screws should be tightened. The angle between the branch line and the lamp body should not be less than 330°, and the lamp body should be perpendicular to the road.
3. After the body of the long-arm lamp is installed, the front end should be flexed by about 100M/M.
4. The horizontal line of the long arm lamp should be tight and flat.
5. At the junction of the horizontal line and the vertical line of the long arm lamp, there must be a transition bow.
6. Ballasts, capacitors, and lamp insurance must be installed at the lamp holder.
Increasing the illuminance may reduce the error rate. In areas where errors may continue to exist, it is recommended to use a higher illuminance. In areas where errors are prone to errors due to high-speed operation during the production process and their nearby areas, it is recommended to use higher illuminance and color rendering light sources.
In a work area without windows or natural light, lower illuminance can easily make people emotionally depressed. In order to make the staff feel comfortable and happy, it is recommended to use a light source with higher illuminance and high color temperature. (Illumination should not be less than 500lux) For areas where staff need to work at night, it is recommended that the illumination should not be less than 500lux. The brightness contrast between the working surface and the environment must be considered. A good illuminance contrast can reduce errors and reduce fatigue.
Road lights
Precautions for road lamp installation:
1. According to the actual lighting needs of the work site, determine the installation position and method of the lamps and ballasts, and then prepare the corresponding length of three-core cables according to the distance from the lamp to the ballast contact and the distance from the ballast to the 220V power contact Cable (the cable provided with the lamp can be used for a distance of no more than 2 meters).
2. When the distance between the lamp and the ballast contact exceeds 2 meters, the three-core cable needs to be replaced. That is, use an Allen wrench to unscrew the six hexagonal bolts of the lamp shell, pull out the lamp body part, remove the three-core cable that comes with the lamp, and then connect the prepared three-core cable according to the original wiring method.
3. Use a socket wrench to unscrew the fastening bolts on the ballast box cover, remove the box cover, and introduce one end of the three-core cable of the lamp into the ballast cavity through the introduction device of the ballast output port, and put the red wire into the ballast cavity. , The black wire (or blue wire), and the yellow and green wires are respectively connected to the 4, 5, and 6 terminals of the ballast, and then tighten the compression nut.
4. Pass one end of the prepared three-core power cable into the ballast cavity through the introduction device of the ballast input port, and then connect the L wire (live wire), N wire (neutral wire), and ground wire to the ballast respectively Screw the compression nut on the wiring terminals at positions 1, 2, and 3 of the device.
5. Close the ballast box cover and tighten the fastening bolts, and finally connect the other end of the three-core cable to the 220V power supply according to the explosion-proof requirements.
6. When replacing the bulb, first cut off the power supply, check whether the hanging chain is hung properly, and then use an Allen wrench to unscrew the six hexagon socket bolts on the lamp shell, carefully pull down the lamp body part to separate the lamp body from the lamp cap shell. Unscrew the old bulb and replace it with a new one.
