YCB扁电缆

江苏春晨电缆有限公司生产YCB扁电缆,白炽灯的发光原理：白炽灯是利用灯丝电阻电流的热效应（电能转换为热能），使灯丝温度上升到白炽程度而发光（热 能转换为光能）的，由于高温灯丝的蒸发，日久使用后在白炽灯玻璃壳内易产生沉积物而发黑，使其透 光性能降低而影响发光效率，所以白炽灯发光效率较低。


The luminous principle of incandescent lamp: incandescent lamp uses the thermal effect of filament resistance current (electric energy is converted into heat energy) to make the filament temperature rise to incandescent level and emit light (heat energy is converted into light energy). Due to the evaporation of high-temperature filament, it is easy to produce deposits and blacken in the glass shell of incandescent lamp after long-term use, making it transparent The luminous efficiency of incandescent lamp is low because of the low luminous performance.






白炽灯的种类很多，按工作电压分，有6、12、 36、和220伏等四种，其中36伏以下属于低压灯泡，YCB扁电缆用于局部照明和携带照明，在安装白炽灯泡时，要注意灯 泡的工作电压与线路电压必须一致，若误把36伏灯泡接人220伏的线路，由于电压过高，流过灯丝的 电流过大，会使灯丝烧坏，相反，若误将220伏的灯泡接人36伏的线路，则由于电压过低，灯泡就会发 不出光来。


There are many kinds of incandescent lamps. According to the working voltage, there are 6, 12, 36, and 220 v. among them, low-voltage bulbs below 36 V are used for local lighting and portable lighting. When installing incandescent bulbs, it should be noted that the working voltage of the bulb must be consistent with the line voltage. If the 36 V bulb is connected to the 220 V line by mistake, it will flow through the filament because the voltage is too high If the current is too high, the filament will burn out. On the contrary, if the 220 volt bulb is connected to the 36 volt line by mistake, the bulb will not emit light due to the low voltage.
