如何确定变压器的参数：Fluorescent lamps have applications in most areas
of lighting, where they give longer lifetime and lower
power consumption for equivalent light output
compared to filament bulbs, with the disadvantage
of higher initial cost. In operation, a voltage is applied
across the ends of a sealed glass tube containing
mercury vapour, causing the vapour to be ionised.
This ionised vapour radiates light in the ultra violet
part of the spectrum, which is converted to visible
light by a fluorescent coating on the inside of the tube.， 大小：6.82 MB
