Excited by the current, the mercury atoms emit ultraviolet light, which bombards the phosphor coating on the inside of the tube.
被电流激活后，汞原子发出紫外光，轰击被覆在电子管内部的磷。
2
The phosphor absorbs some of the blue light and is "pumped" into an excited state.
磷光层吸收某些蓝色光线之后，就能被“启动”进入一种兴奋状态。
3
The phosphor is excited by the lights emitted from the semiconductor devices to emit light having a wavelength different from those of the lights emitted from the semiconductor devices.
