Communication system

Nowadays when communication has been widely popularized, communication devices may be available on remote high mountains and deserted islands. Besides, there is a growing demand for telecommunication equipment to have more stable performance. But what is the stability of these devices as they are more exposed to natural environments? According to previous practice, hostile environment such as ice, snow, rainstorm, and haze will cause serious damage to telecommunication devices. But why will such damage occur? That is because a large amount of heat is generated when the devices are in operation. To protect the sophisticated electronic components in the device...

Lighting industry

Lighting fixtures are available all over the world. Some are on the humid equator, in the scorching Sahara Desert and the freezing Siberia. Others are in the wind and sand, and the rainstorm. How to enable lighting fixtures to bear the test of the atrocious weather proves to be a great test before the designers. The biggest problem in the past was the water and dust absorbed in the lighting resulting from temperature change-incurred negative pressure. Designers used to believe that such problem was caused by fragile casing and insecure installation. Therefore, more airtight lighting was adopted as a way of coping with the problem...
