电视机的外壳一般做成黑色,人们对此产生种种的猜想,其实,电视是物理学发展的产物,外壳的着色也存在着物理的学问。电视机工作时,机内温度升高,影响电视机的工作性能,由于黑色的物体对热的辐射本领强,因此黑色的外壳有利于电视机散热。黑色的物体能把所有的色光都吸收,所以外壳做成黑色,可减小外壳反射光对视觉的干扰达到最佳的收视效果。电视机工作电压高,有触电危险,黑色是冷色,不容易引起人们(尤其小孩)的兴趣,可减少人们触摸和
The outer shell of the TV is generally made of black. People have all kinds of conjectures. In fact, television is the product of the development of physics, and the coloring of the outer shell also has a physical knowledge. When the television is working, the temperature inside the camera increases, affecting the working performance of the television. Since the black object has strong radiation power to the heat, the black housing is favorable for the heat dissipation of the television. The black object can absorb all the colored light, so the shell is made of black, which can reduce the visual interference of the reflected light from the shell to achieve the best viewing effect. TVs have high operating voltages and are at risk of electric shock. Black is cool and it is not easy for people (especially children) to be interested in them.
