First, we first understand that the design structure of laneway lamp power driver board, it adopt the structure principle of non electrolytic capacitor and high-power integrated LED, utilization of high material, so as to avoid the the electrolytic capacitor achieve the dry electrolyte and excursion of temperature in high temperature。To creating favorable conditions for improving the reliability of products。
Then we’ll know the compensation design of laneway lamp power driver board, it is using the design of high power factor active compensation, active compensation is more reasonable than the explosion-proof headlight design more comprehensive, complete machine power factor in the use of voltage range, rated according to the requirement of field environment, not less than 80%, not more than 95%, in a plurality of lamp body work together can effectively reduce the internal grid work pressure.
Third. To understand the application technology of laneway lamp power driver board, it is used a wide voltage application technology, which will be the overall power in addition to the rated voltage (90 ~ 140VAC), to determine the installation method and position of lamps on the lower limit。
voltage of electricity grid can keep the laneway lamp does not fully loaded in the 30VAC output, still show certain illumination, in the grid voltage reaches 265VAC, laneway lamp can keep a full load output in a short time, network wide voltage adaptive disturbance, type design can effectively resist the fluctuation of power grid。
Fourth, understand the laneway lamp power driver board according to the mine locale power fluctuations, interference of big situation, by using multistage interference protection measures, more, making better use of the characteristics of laneway lamp, miner’s lamp is much bigger than the advantage, the input point of the power adopts two grade common mode rejection, two grade differential mode rejection, one grade micro gap discharge surge absorption device and multistage design of anti-interference capacitor, prepared the corresponding length diameter Φ8 ~ 10mm three core cable sheathing line, can effectively restrain the power grid of coal mine driving at laneway cause of voltage is too large。anyway it is can shielded the interfere form high power pump and fan machine fast startup。
Fifth，To understand the isolation room design of lamp power driver board and connected to the grid line, effectively reduce the contact chance of spark and explosive gases, multistage seal is also beneficial in the isolation of external gas and electrical part。
Sixth，To understand the laneway lamp lighting optical design structure, light distribution more reasonable. first You must cut off the power supply，the effective distance of Rate power is 2 times that of the traditional laneway lamp。High quality lamp power driver board to produce high-quality laneway lamp in The selection。
