one major Multi function street 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 Multi function street lamp The use of crystal oscillator time control can make the time control more accurate.

Considering that street lamps are conductors, one way is major Multi function street lamp Combination of external lightning protection and internal lightning protection. As the material of street lamp is conductor, it is equivalent to lightning rod, and downlead and grounding grid need to be installed in the design. These systems constitute the external lightning protection system. After the completion of the external lightning protection system, the fire and personal safety accidents caused by the direct lightning stroke of the street lamp can be avoided. After the completion of external lightning protection, the internal lightning protection system can protect the equipment by grounding and setting voltage protection. major Multi function street lamp The internal lightning protection system is ready to prevent induced lightning and other forms of overvoltage intrusion, which may damage the power supply. This is also beyond the protection of external lightning protection system. Therefore, the built-in internal protection and external protection can complement each other.

There are many types of LED street lights, which can be classified according to the following categories. 1 major Multi function street lamp Height of street lights: high pole street lights, medium pole lights, street lights, garden lights, lawn lights; 2, according to major Multi function street lamp Material of lamp pole: hot-dip galvanized railway lamp, steel street lamp and stainless steel street lamp; 3. Divided by shape: Chinese lamp, antique lamp, landscape lamp, single arm street lamp, double arm street lamp. 4. According to the power supply mode: urban circuit light, solar street light, wind solar complementary street light.

1. Advocate the concept of environmental protection and recycling globally. Traditional lamps contain many harmful substances. If the bulb fails, harmful substances will volatilize into the atmosphere. But, Baoding major Multi function street lamp It does not contain harmful substances at all and can protect the environment. Shandong LED ceiling lamp is recognized as a green lighting product in the 21st century. 2. Shandong LED mining lamp saves energy, has a long service life and saves maintenance costs. The power consumption of LED industrial and mining lamps in Shandong Province is generally less than one third of that of traditional lamps, and their service life is 10 times that of traditional lamps. It can be used for a long time without replacement, thus reducing the labor cost. 3， Baoding major Multi function street lamp It can also protect eyesight. Traditional lamps use AC power, but Shandong LED industrial and mining lamps directly convert AC power to DC power without flickering, which can protect the eyes. 4. Shandong LED mining lamp has high efficiency and luminous efficiency.
