对于黑暗,人类有一种与生俱来的恐惧。当我们远离城市,在长途跋涉后的夜晚,照明自然是件头等大事汽灯VS电灯发光需要能量,能量从何而来?这是我们面对的第一个问题,那无非两种方法:一种是通过热来发光,另一种方法是通过电来发光。由此,户外照明用具大致上先分两派,一是依靠燃烧来照明的汽灯,二是通过电池来发光的电灯。能量来源的不同决定了两种发光效果的不同。
For the dark, human beings have a born fear. When we are away from the city, in the night after a long journey, lighting is a top priority Gas lamp VS Electric light requires energy, energy come from? This is the first question we face, that is nothing more than two ways: a It’s glowing by heat, and the other way is by electricity. As a result, outdoor lighting appliances roughly divided into two camps, one by burning to light the gas lamps, the second is through the battery to light the lamp. The difference in the source of energy determines the difference between the two luminescence effects.
