1. Explosion proof sign and basic sign: including product name, model, manufacturer name, registered trademark, manufacturing date, etc.

LED explosion-proof lamp

2. The quantity of explosion-proof certificate proves that the product has passed the formal test of explosion-proof testing station. Some products have an "x" symbol behind the explosion-proof certificate number, indicating that the product can only be used under certain special safe conditions. The specified conditions shall be clearly stated in the lamp shade or product manual.

3. Performance safety signs: including rated voltage, current, rated frequency, power supply and quantity, allowable ambient temperature and specific applicable environmental signs.

Key design points include:

1. The chip selection must first use a high lumen, dedicated low-power chip. The most mature chips are IW and 3W chips; The second package is better to use the common process, which can be done well

2. Light distribution design has great influence on lighting performance. LEDs are directional light sources. Professional optical grading design must be adopted to meet the standards and requirements of site lighting. Recommended reading: How to use LED explosion-proof floodlight

3. Thermal conductivity design is very important. The overall professional thermal conductivity of LED lamps must be designed to meet the operating temperature requirements of LED chips.
