德国研制出一种变色灯具,它由灯头、灯管和灯罩三部分组成,灯头是热源又是光源。玻璃制成的灯管内装一定量的三氟三氯乙烷液体,液体内悬浮着数十片真空镀铝的涤纶薄膜。灯管的底部涂着红绿色彩。通电后,灯管内的液体上下热对流,悬浮在液体内的薄膜随着液体上下翻动,从而把射入液体内的色光折射到半透明的灯罩上,漫射出五彩缤纷、变幻莫测的色光。变色灯既可作装饰,还可作璀璨华丽的大锦 Germany developed a color change lamp, which consists of lamp, lamp and lampshade in three parts, the lamp is the heat source is light. The glass tube made of a certain amount of trifluoro-trichloroethane liquid, liquid suspension of dozens of vacuum aluminized polyester film. The bottom of the lamp is painted red and green. After the power is turned on, the liquid in the lamp tube heat convects up and down. The film suspended in the liquid flipping up and down with the liquid refracts the colored light entering into the liquid onto the translucent lampshade, diffusing a variety of colorful and unpredictable shades.
