In order to make the LED drive power supply waterproof, we generally seal the electronic components by filling glue. The glued material is generally made of silica gel and epoxy resin. Silicone is cheap, has good air tightness, strong adhesion and high hardness. But it is easy to turn yellow and not tolerate temperature. Epoxy resin is resistant to high temperature, can be reflowed, is not easy to yellow, and has stable performance. However, it has strong water permeability, low hardness and high price. We should choose different materials for different types of customers.

With the rapid development of road traffic construction in China, the construction scale and quantity of highway tunnels are also getting larger and larger. Tunnel lighting has also emerged as problems such as energy conservation and safety. With the maturity of LED light source technology, domestic The lighting industry has also carried out the research and application practice of LED in highway tunnel lighting. Therefore, combining advanced control methods in tunnel lighting, using a new generation of light source with high luminous efficiency, good stability and long life will become a demand. And trends

This article details the issues that may arise after applying the drive power to landscape lighting.
