What Should You Pay Attention to When Using LED Explosion-Proof Lights

After purchasing from LED explosion-proof light manufacturers, there are several operational considerations to ensure safety and stability during use.

1. Temperature:

Be mindful of temperature increases, as a rise in external ambient temperature can decrease the internal resistance of the LED light source. If powered by a voltage-stabilized source, this can cause an increase in working current. If it exceeds the rated working current, it can affect the lifespan of the LED explosion-proof light, and in severe cases, “burn out” the light source. Therefore, it’s best to use a constant current source to ensure that the working current of the LED explosion-proof light is not affected by external temperatures.

2. DC Power Supply:

LED explosion-proof lights should be powered by a direct current source. Unlike explosion-proof searchlights and flashlights, some manufacturers use a “resistance-capacitance reduction” method to power LED products to reduce costs, which can directly impact the lifespan of the LED product. Using a dedicated switching power supply (preferably a constant current source) will not affect the product’s lifespan, though the cost may be relatively higher.

3. Sealing:

If LED explosion-proof lights are used outdoors, they face challenges with waterproof and moisture-proof sealing. Poor handling can directly impact the product’s lifespan. Some high-quality manufacturers use traditional epoxy resin “potting” methods to seal LED products. While effective, this method can be cumbersome for larger LED products, unsuitable for some applications, and may increase the product’s weight.

4. Anti-static Measures:

During the manufacturing process of LED explosion-proof lights, the same processing methods as explosion-proof flashlights should be used to implement anti-static measures. For instance, workbenches should be grounded, workers should wear anti-static clothing, rings, and gloves, and if possible, install anti-static ion fans. Additionally, maintaining workshop humidity around 65% is essential to prevent static electricity, especially since green LEDs are more susceptible to static electricity, electric fields, and currents, which are physical quantities produced by the presence or movement of electrical charges.
