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.

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.

Main pole of high pole lamp: major City circuit lamp When the height of the main pole exceeds 20m, the steel plate with a wall thickness of 5.6mm is usually used as the main material. After the overall welding of the high pole lamp, the internal and external surface layers need to be hot-dip galvanized and qualified galvanized. This process can ensure that the main pole will not rust for 15 years. Lifting system: the lifting system is regarded as the core part of the high pole lamp. The landing action of the light panel depends entirely on the landing system. The landing system of high pole lamp is mainly hoist and wire rope. First, install the elevator on the main rod. Weathering and rain will not cause line aging. Secondly, the hoist seldom starts. If major City circuit lamp If the light source has not been damaged in ten years, it will not need to be touched in ten years. Lamp cap: Whether it is LED lamp cap or low pressure sodium lamp, the light source is the main symbol of the whole set of high pole lamp. If the light source is broken and the high pole lamp is broken, the selection of light source quality is particularly important.

First, we need to observe major City circuit lamp The workmanship of the mask and its luminous effect. This depends on how much light the bulb lamp shade emits to the light source. When viewing the mask, you can view its shape, whether the light transmittance and thickness of the bulb are the same, and check the approximate blur of the mask. We need to see if the material of the bulb is suitable for heat conduction. You can test in the field. After working for several minutes, observe whether there is odor above the bulb when the temperature rises. After that, we will also check the lamp body temperature after the power is turned off. The lower the temperature, the better. ordinary major City circuit lamp It will change due to the change of ambient temperature. When selecting bulb lamp, you need to check its color temperature. Generally speaking, the color temperature should not be too high or too low as long as it can meet the normal household lighting needs.
