one major Square lamp Courtyard lamp The charging circuit adopts a dual MOS series control circuit, which can reduce the voltage loss of the circuit by nearly half compared with the use of diodes. The use of PWM energy-saving control greatly increases the power consumption. 2. The load mode adopts pure light control. When the light is dark, the light sensor system will automatically light up. 3. Scientific battery management method. When over discharge occurs, the battery voltage will promote charging. After maintenance and compensation, it can be used normally. Direct charging and floating charging are used to connect rechargeable batteries. 4. All restrictions of all industrial chips and closed components can operate normally in cold, high temperature and humid environments. At the same time, major Square lamp Courtyard lamp The use of crystal oscillator time control can make the time control more accurate.

The bulb shall be firm and upright and shall not be loose or skewed. If the enamel umbrella is corroded or deformed major Square lamp Courtyard lamp It needs to be replaced in time. Before using electric tools, please check whether the wiring, plug, socket, grounding and leakage protection devices are in good condition. Do not use them if they are damaged. Safety slogans, warning signs and safety operation instruction boards shall be set up on the construction site. Materials on the site shall be stacked orderly and stably and handled from top to bottom. When using hand-held electric tools, please wear personal protective equipment and the power cord should be empty. It is forbidden for non operators to use it on site major Square lamp Courtyard lamp Power switches, wires and various mechanical equipment. Outdoor construction is not allowed in rainy season. Outdoor construction should be carried out after the rain is dry. The Quality Safety Department is responsible for preparing labor protection articles to ensure the safety of construction personnel.

1. Be able to monitor the temperature of the light source chip pad of the street lamp itself or the temperature of the lamp shell and conduct fault diagnosis; 2. Remote measurement of electrical parameters such as street lamp current and voltage, remote switching of street lamps, remote viewing of on-site operation of important road sections, etc; 3. According to major Square lamp Courtyard lamp The monitoring data of can timely grasp the abnormal position and reason of street lights, and carry out purposeful maintenance without having to go to the whole city for inspection, which speeds up the speed. 4. It has daylight sensor or on-board sensor dimming, energy saving control, time control and even RTC dimming; 5. In some areas with few people and vehicles, it can be controlled at half bright time in the middle of the night, but when people and cars pass by, major Square lamp Courtyard lamp They will reach the distance ahead and in a few cases restore the original brightness. Seconds. 6. The lighting standard level of the same road will change with time and traffic flow.

1. Strong anti-static capability: LED with strong anti-static capability has a long service life. 2. Brightness: The price of LED varies with its brightness. 3. Wavelength: LEDs with the same wavelength and color are expensive. 4. Luminescence viewpoint: LEDs for different purposes have different luminescence viewpoints. 5. LED chip: major Square lamp Courtyard lamp The illuminant of is a chip, and the price of different chips varies greatly. 7. Colloid: Generally, the colloid of LED is epoxy resin. LEDs with UV resistance and flame retardancy are more expensive. 8. Chip size: the chip size is represented by the side length. Big chip major Square lamp Courtyard lamp Its quality is better than that of small chips. The price is proportional to the chip size. 9. Radiator: The radiator can see the appearance of the lamp. Temperature will affect the life of LED lamp beads. Counting plays a vital role. 10. Power supply: According to the plan requirements of different manufacturers, it can be divided into two types: constant current power supply and constant voltage power supply.

During use, the bulb will be hit by wind and rain, which may cause its angle deviation, thus affecting the lighting effect. If any deviation is found, it must be adjusted in time. Check the bulb surface regularly. If on major Square lamp Courtyard lamp Cracks found on the surface glass of the bulb may cause rainwater to enter the bulb, which will seriously affect the use effect and service life of the bulb. The bulb should be removed immediately and sent to the original factory for repair. Avoid all kinds of serious accidents, such as leakage. Clean the lamp regularly to maintain its brightness. Turn off the lamp before cleaning it major Square lamp Courtyard lamp The power supply of the lamp shall be cleaned with a dry cloth or dry cloth to prevent the lamp from being damp, let alone with chemical or corrosive substances. Otherwise, the bulb will be corroded, which may cause accidents.

The working voltage of a single bulb for LED tunnel lighting is very low, about 3V, so the power consumption of a low-voltage working environment is half of the power required for the same strong light. The tunnel lamp has a long service life and does not need regular maintenance and inspection. After a period of use, the traditional major Square lamp Courtyard lamp The brightness of the tunnel lamp will be greatly reduced, but its attenuation is only 20% of that of the tunnel lamp. Moreover, the tunnel lamp is small in size and can be made into various shapes to adapt to various environments. The shell of the tunnel lamp is of integrated design, which is durable and not easy to be damaged. Each light source inside can be installed and removed separately, which is very convenient in the future maintenance process, and the overall design can ensure good heat dissipation effect. The heat dissipation rack inside the shell, the airflow and the heat emitted by the full contact with the air, effectively reduce the major Square lamp Courtyard lamp And prolongs the service life of the tunnel lamp.
