On the one hand, the choice of lights on the lighting and LED lighting, is more people will choose, mainly durable!

传统射灯多采用卤素灯，发光效率较低、比较耗电、被照射环境温度上升、使用寿命短。

Halogen spotlights to use more traditional, lower light, more power, increased by exposure to ambient temperature, short life.

So if we think about the work function for zinc, and the work function for zinc is 6.9 times 10 to the -19 joules, do we expect that when we shine our UV light on the zinc, we'll be able to eject electrons?

如果我们考虑锌的功函数,它是6，9乘以10的-19次方焦耳，我们是否可以预测当,用紫外灯照射锌时，我们可以射出电子呢？
