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 City circuit 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 City circuit 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.

The bulb shall be firm and upright and shall not be loose or skewed. If the enamel umbrella is corroded or deformed major City circuit 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 City circuit 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.

The ultraviolet ray of LED energy-saving lamps is not particularly strong. major City circuit lamp It will not appear after using for a period of time. It may feel particularly strong and will not produce ultraviolet light, so it will not fade, will not be disturbed by mosquitoes, and the indoor sanitation can also become clean. major City circuit lamp It can also protect our eyes well. When starting, the time is faster, so it will not flash, so it can protect the eyes. The main advantage is that it can save power and has a longer service life. This is a good and reasonable guarantee. When you use it, you don't have to worry about life problems or abnormalities, nor about the cost of replacing the bulb. Moreover, when you use it, it is relatively robust and does not worry about frequent use. This would be bad.

one major City circuit 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 City circuit lamp The use of crystal oscillator time control can make the time control more accurate.
