变色灯是目前正在发展的家用装饰性灯具。它还可以用来美化其它家用电器,使这些产品更为新颖别致,为它们增添光彩。这种灯的变色原理是,利用液体介质和固体介质的比重差,借助光源发出的热量推动液体介质上下循环,从而带动其内的固体介质浮动翻滚。灯光经运动固体介质的反射面反射和液体介质的折射传送出去,形成闪烁的变色光。也有利用两种或多种比重及热容量相当,颜色不同的非共溶性液体,或机械方式变色的。变色灯的基本结构如图1所示。
Discoloration lamp is currently developing home decorative lighting. It can also be used to beautify other household appliances, so that these products are more novel and unique, add luster to them. The principle of discoloration of this kind of lamp is to make use of the difference of the specific gravity of the liquid medium and the solid medium to promote the liquid medium to circulate up and down by means of the heat emitted by the light source so as to drive the solid medium in it to float and float. The light is reflected by the reflecting surface of the moving solid medium and refracted by the liquid medium to form a flickering discoloring light. It is also possible to use two or more non-co-soluble liquids with comparable specific and thermal capacities, different colors, or mechanically discolored. The basic structure of the color change lamp shown in Figure 1.
