Street lamps refer to lamps that provide lighting functions for roads, and generally refer to lamps within the range of road lighting in traffic lighting. Street lamps are widely used in various places that require lighting.

Lamp height

Height determines the field of view, so choosing a good height determines the lighting field of the street lamp.

1. The installation height of lighting fixtures on the same street must be consistent (from the luminous center to the ground). Small bend light, one meter light, 5-6 meters long arm light and pendant light for ordinary streets, 6.5-7.5 meters fast lane arc light, not less than 8 meters slow lane arc light, not less than 6.5 meters

2. Special lamp types are installed according to design requirements, and the height of the lamp is roughly equivalent to the width of the road that needs to be illuminated. When illuminated on one side only, H Å L When illuminated on both sides, H Å L/2, where H is the installation height of the lamp in meters, L is the road width in meters

Lamp elevation angle

1. The elevation angle of each street should be determined by the width of the street and the light distribution curve of the lighting fixtures, and the elevation angle of each street should be consistent.

2. When the lamp head is adjustable, the centerline of the light source should fall within the range of L/3-1/2 of the road width.

3. After installation, the lamp body of a long arm lamp (or support arm lamp) should be raised 100 millimeters higher on the lamp head side than on the pole side.

4. The elevation angle of special lighting fixtures should be determined based on the light distribution curve.

Street lighting fixtures

1. The lighting fixtures should be firm and upright, and there should be no looseness or skewness.

2. The lampshade should be intact and not broken.

3. Enamel umbrellas rusted and deformed should be replaced.

4. The reflective mirror surface of the lamp is invalid and should be replaced.

5. The reflector of the lighting fixture should not be damaged or deformed during transportation and installation. The lampshade should be equipped with a rubber ring and wiped bright. When the lamp mouth is made of broken porcelain and exposed copper, it should be replaced.

6. Lamps and lamp bodies shall not be bent, and the fixing screws of each part shall be tightened with spring eyeliner. Do not loosen them.

7. The cast iron lamp head has cracks, falls off blocks, and cannot be used. It is not qualified without rubber.

8. The lamp body clamp should be suitable for the electric pole, and the device should not be too long.

9. The transparent cover and reflector of the lamp body should be cleaned and wiped clean during maintenance, and those that cannot be cleaned on site should be replaced.

10. The buckle of the transparent cover should be complete and easy to use, to prevent the cover from falling off. Reliable hooks should be used.

11. The dust proof felt strips of the lighting fixtures should be complete, and any unevenness should be repaired and replaced.

12. The lamp holder and the lamp tube flange must be matched with cracks and scratches, and the screws must be complete. The bolt length should be able to penetrate the lamp holder flange.

13. When a lamp is suitable for bulbs of different specifications, the fixing point of the lamp outlet should be adjusted to the same position as the bulb capacity to obtain the optimal light distribution curve.

14. All types of iron parts should be free from severe rust, cracks, scars, etc. If the paint peels off, rust should be removed, painted or galvanized.

15. The lamp head leads of enclosed lamps should be protected with heat-resistant insulation tubes (asbestos or porcelain tubes).

Process flow

Insulation testing → street lamp installation → electrical equipment installation → testing, pressure testing → self inspection and completion acceptance of the electrical system. According to the civil construction sequence, do a good job in embedding cables and conduits, and also do a good job in preventing blockage of embedded conduits.

Construction methods

1. Insulation test: Use a tramegger to measure the insulation resistance between wires and to ground, check if the cable is intact and there is no leakage. All test values should meet the requirements of the specifications. After the telemetry is completed, the core wire should be discharged to ground. The end of the cable should be sealed with rubber wrap and then wrapped with adhesive tape.

2. Street lamp installation:

(1) The installation height (from the light source to the ground), elevation, and installation direction of street lights at the same location should be consistent.

(2) The longitudinal centerline of the lamp installation and the longitudinal centerline of the lamp arm should be consistent, and the horizontal line of the lamp should be parallel to the ground. After fastening, there should be no deviation visually.

(3) The lamp head is firmly fixed, and the adjustable lamp head should be adjusted to the correct position according to the design. The lamp head wiring should comply with regulations

(4) Various nuts should be tightened with gaskets and spring washers.

1. Efficient and energy-saving: LED Street Light use semiconductor materials to emit light, which has a higher energy conversion efficiency compared to traditional incandescent and fluorescent lamps, with a photoelectric conversion efficiency of over 80%. The energy efficiency of LED lighting fixtures has been improved by 30% to 50% compared to traditional lighting products, which can significantly reduce electricity costs.

2. Long lifespan: LED Street Light have a long lifespan, usually reaching over 50000 hours, far exceeding the lifespan of traditional light sources. The long lifespan of LED Street Light reduces the frequency of lamp replacement, reduces maintenance costs, and reduces work downtime.

3. Good environmental adaptability: LED lighting fixtures generate low heat during operation and do not generate as much heat as traditional light sources, reducing the problem of indoor temperature rise. In addition, LED lighting fixtures do not contain harmful substances such as mercury, making them environmentally friendly.

4. Rich color: LED lighting fixtures can change the emitting color by adjusting the ratio of semiconductor materials and controlling the current, which can achieve various color displays and lighting requirements. The color richness of LED lighting fixtures can meet the needs of different occasions and environments.

5. Good lighting quality: LED lighting fixtures have advantages such as high color temperature and high color rendering index, which can provide lighting effects closer to natural light, making the human eye feel more comfortable, improving work efficiency and protecting vision.

6. Dimmability: LED Street Light can achieve dimming function by adjusting the current or using a dimmer. They can adjust the light intensity according to different needs, meet the lighting needs of different occasions, and provide a more comfortable lighting environment.

7. Quick response: LED Street Light have a short start-up time and can instantly reach maximum brightness without preheating, providing instant lighting. This is very practical for situations that require frequent switching of lighting fixtures.

In summary, LED lighting fixtures have the advantages of high efficiency, energy conservation, long lifespan, good environmental adaptability, rich colors, good lighting quality, dimming ability, and fast response. With the continuous development of LED technology, the application prospects of LED Street Light in the lighting industry will be even broader.

LED street lighting mainly has the following advantages:

The first is energy-saving, which is less than half of the power of ordinary energy-saving lamps, and light sources with the same power consumption are more energy-saving.

Second: Long service life. The worst-case service life of LEDs is usually over 5000h (H). There is no heavy metal manufacturing process, which is environmentally friendly.

Thirdly, the colors of LEDs can be varied, and there is a lighting conference to adjust the color of the lights.

Fourth: Good LED brightness, DC drive, no flicker, eye protection. However, the light is very harsh, and an aperture should be installed to make the light softer.

Fifth: The voltage of LED is DC voltage, which is relatively low and can be installed in the bathroom. At least it won't be damaged by condensation water.
