How to choose the shell material of LED tri-proof lamp?

As a lighting device suitable for special environments, the selection of shell materials for LED triproof lamps is crucial. The shell is not only related to the appearance of the product, but also the basis for ensuring the stable and safe operation of LED lamps in harsh environments. When selecting the shell material of LED tri-proof lamps, it is necessary to comprehensively consider various factors to ensure that the selected material has outstanding performance.

1. Heat resistance of materials
LED tri-proof lamps usually need to work in high temperature environments, so the heat resistance of shell materials is crucial. 850℃ GWT (glow wire test) is an important method to evaluate the heat resistance of materials. When the glow wire is heated to 850℃, the shell material that meets the 850℃ GWT requirement can extinguish the flame within 30 seconds after the glow wire is removed after contact with the material, and the packaging silk paper under the sample and the sample itself will not ignite. This material can maintain stable performance at high temperatures to prevent the product from deformation, melting or burning.

2. Protective performance of materials
The shell material of LED tri-proof lamps must have good protective performance and be able to resist the invasion of external factors such as water, dust, and corrosion. PC (polycarbonate) is one of the commonly used materials for the outer shell of LED tri-proof lamps. It has the characteristics of good light transmittance, high hardness, impact resistance, stable high and low temperature resistance and chemical corrosion resistance. In addition, materials such as ABS, PMMA, and PVC also have certain protective properties, but the specific selection depends on the use environment and needs.

3. Durability and stability of materials
The service life of LED tri-proof lamps is usually long, so the outer shell material needs to have high durability and stability. When selecting materials, attention should be paid to their anti-aging, anti-ultraviolet, and impact resistance properties to ensure that the product is not easily damaged or deformed during use.

4. Cost and environmental protection of materials
In addition to performance and protection requirements, cost and environmental protection are also factors that need to be considered when selecting the outer shell material of LED tri-proof lamps. On the premise of meeting performance requirements, choosing materials with moderate cost and good environmental protection can help reduce product costs and improve market competitiveness.

The selection of outer shell materials for LED tri-proof lamps needs to comprehensively consider factors such as heat resistance, protection performance, durability and stability, as well as cost and environmental protection. Only by selecting suitable materials can we ensure that LED tri-proof lamps work stably and safely in harsh environments and bring better user experience.
