The characteristics of the LED street light itself - unidirectional light, no light diffusion, to ensure light efficiency.

2. With a unique secondary optical design, the light of the LED street light is irradiated to the area required to be illuminated, which further improves the illumination efficiency and achieves the purpose of energy saving.

3. The light decay is small, the light decay in one year is less than 3%, and the illuminance requirements for road use are still met after 10 years of use.

4. The LED street light has an automatic control energy-saving device, which can reduce the power to the greatest extent possible and save electricity while meeting the lighting requirements of different periods.

5. The LED street light is a voltage device, the voltage to drive a single LED is a safe voltage, and the power of a single LED of the series products is 1 watt, so it is a safer power supply than using a high-voltage power supply, especially suitable for public places.

6. Long life: can be used for more than 50,000 hours.

7. High luminous efficiency: lamp beads with lumen value ≥100LM are used.

8. Simple installation: no need to bury cables and rectifiers and other devices, directly install the LED street lamp head on the lamp pole or connect the light source to the original lamp housing.

9. Reliable quality: All circuit power supplies are made of high-quality components, each with individual overcurrent protection, so there is no need to worry about damage.

High-pole lighting is a large-scale lighting facility, which has the advantages of wide illumination range, good lighting effect and convenient maintenance. In order to ensure normal and safe operation, the approval of newly installed high-pole lighting facilities should be carried out according to the regulations of the Ministry of Construction, and the maintenance content should be clarified: lights Rods, lamps, metal anti-rust paint, clean lubricating oil filtration mechanism and fasteners inspection and replacement of damaged light source electrical appliances and circuits, etc., maintenance personnel should obey the unified command of the person in charge of the site, and take corresponding safety measures.

Although the functions of smart street lights are much more than that of ordinary solar street lights, their cost is not much higher than that of ordinary solar street lights. There are two reasons: it is due to the light control, voice control and other technologies used in smart solar street lights. The cost is negligible compared with the main components of the solar energy, and mainly depends on the design of its software. The street lamp manufacturer with the function of the late-night power saving mode is equivalent to saving the time of continuous lighting, so that it can rely on the shorter continuous lighting. Time to reselect lower power batteries and solar panels, saving the cost of buying hardware.

Lamp maintenance and replacement.

Carry out a comprehensive overhaul according to the maintenance plan of the high-pole lighting equipment, carefully check the operation of the lamps, cables of the light source and other equipment, and use the temporary power cord to connect the lamps for electrical maintenance. , the following problems exist in routine maintenance.

(1) During the process of retracting and unwinding the wire rope, on the one hand, check the appearance of the wire rope, and on the other hand, pay attention to whether the wire rope is overlapped, the wire rope is entangled, corroded, broken strands and serious stress phenomena, and check whether the sliding parts are flexible and reliable.

(2) Replace the damaged light source electrical appliances, cables, etc., and check whether all the fixing bolts are loose, safe and reliable, whether the positioning pins and automatic hooks are flexible and reliable, etc., and those with serious corrosion must be replaced.

(3) Fixed on the bottom motor, gearbox and transmission mechanism of the light pole, there should be a closed cover to prevent the coil from being damaged by insulation due to moisture. Check whether the gearbox oil is sufficient, whether the oil is black or has impurities, and move the motor. The drive mechanism should be placed in a dry place, and the insulation resistance test should be carried out before use (not less than 1MΩ) before it can be used.

(4) The AC contactor, thermal relay, travel switch, and control device of the command controller in the control circuit of the high pole lamp should be carefully checked before operation. The electrical components found in the inspection should be replaced as soon as possible. Ill run.

(5) For the grounding protection device of high pole lighting facilities, the lightning protection device must be checked every year during the rainy season, and the grounding resistance should be tested, and the grounding resistance value should not be less than 10Ω.

(6) The above maintenance contents must be recorded in a ledger.

After the maintenance of the road lights is completed, the electrical parts of the high-pole lighting facilities and the lifting transmission mechanism should be fully checked again. After confirming that they are correct, the lamp panel can be lifted and directly hooked and unloaded before leaving the scene.
