LED灯的驱动器里面都有一个电容，可以把电容理解成一个容量很小的充电电池：当电容内通过电流时，电容会持续充电——充满电以后，电容会一次性将储存的电能全部释放。LED灯闪烁，就属于后一种情况：电容充电的过程中，灯是熄灭的——由于电容内部电流较小，导致充电速度很慢，所以用肉眼是可以看到电灯熄灭的。当电容充满电后，一次性释放电能，会点亮电灯。但是由于储存的电能较少，电灯很快就会熄灭——不停的重复充电、放电，肉眼看到的，就是灯闪烁。

Purpose of HYAT solid insulated filled cable: solid insulated filled cable is suitable for the urban telecommunication line of the local telecommunication network in the town of wuyu, and also for the special network line connecting to the public network. Mainly used for pipeline laying. The inner and outer surfaces of the cable core and the shield layer are filled with oil paste and poured to prevent water intrusion. The mechanical and electrical properties of the cable remain unchanged under conditions of 30~C - 60~C. Structure: wire: annealed bare copper wire, copper wire diameter 0. 32, 0. 40, 0. 50, 0. 60, 0. 70, 0. 80, 0. 90 (mm). Insulating material: high density polypropylene or polypropylene, colour of the insulated wire as indicated by full chromatograph. Pair of insulated wires: twist two different colored insulated wires into pairs at different pitch and use the specified chromatographic combination to identify pairs. Core structure: with 25 pairs as the basic unit, more than 25 pairs of cables are assembled according to the unit, each unit is wired with the unit of specified chromatogram to identify different units. 100 pairs of cables with more than one pair of cables plus 1% of the reserve pair, but not more than 6 pairs. The gap in the core is filled with oil paste. Core tape: wrap with a polygrease film tape. Shielding: metal strip with or without striping, which is longitudinal wrapped outside the core of the cable. Sheath: black low density polymer. Double sheathed cables can also be provided. Identification and marking: cable outer surface sexual identification mark, mark at no more than alternate 1 m intervals, tag contents are: the diameter of wire, line number, cable type, factory name and year of manufacture, marking at no more than alternate 1 m intervals to mark on the surface, but with the tag stagger. Other structures: according to the needs of users, we can provide armored cables HYAT53, HYAT55 and high frequency isolation cables YATG with strengthened mechanical protection layer.
