Explosion proof LED lamp is a kind of electrical equipment used in special industries. It mainly solves the lighting problem. The utility model comprises a lamp housing, a luminous device and a battery arranged in the lamp housing, and a switch arranged on the surface of the lamp housing. A high-power LED module, and a wide voltage input circuit is arranged between the illuminant and the battery; The wide voltage input circuit includes a chip constant current, a chip constant current and a battery power module. The LED module is connected to the [0x4e20 chip, and the power module is sealed with an LED module. Ultrasonic welding is performed between the lampshade and the lamp shell.

One of the most important explosion-proof principles of LED explosion-proof is to limit the temperature of the cabinet surface in contact with the explosion-proof gas, which contains dust, element surface or electronic element surface, and limit the temperature of the electrical contact surface to its minimum ignition temperature or below the ignition temperature. Explosion proof LED lamps for outdoor use need waterproof devices. The explosion-proof LED lamp used in the service station must be shockproof!

Many people believe that explosion-proof LED can be explosion-proof, because its shell can prevent the explosion of dangerous gas inside. Its sealing performance is very good, so it can prevent rainwater from entering. It must be installed outdoors without problems. In fact, this is wrong, which completely confused the two concepts of explosion-proof LED lamps and the protection grade of the housing.

Explosion proof LED lamps are divided into different explosion-proof types according to different explosion-proof principles. Explosion proof LED lamp has explosion pressure, which can withstand the internal gas mixture and prevent the internal flammability around the explosive phase shell of the mixture. Explosion proof LED lamp housing. Obviously, its explosion-proof performance has nothing to do with the protection grade of the shell. The national standards have no special requirements on the degree of protection. While meeting the protection level of the enclosure, the material and impact resistance of the enclosure shall be strictly controlled.

The safest explosion-proof LED lamps are manufactured in accordance with normal operating standards. High temperature arcs, flames or LED explosion-proof lamps that ignite flammable mixtures are not acceptable. Effectively improve the safety level to avoid normal and approved loading standards. These problems exist in electrical equipment. Intrinsically safe explosion-proof LED lamp is a kind of LED explosion-proof lamp. Due to sparks and thermal effects generated under specified fault conditions, all power circuits will not illuminate the specified flammable mixture. These two types of explosion-proof LED lamps will not produce flame or high temperature, or the resulting flame and thermal effects are insufficient to ignite flammable mixtures. Obviously, its explosion-proof performance has nothing to do with the protection grade of the enclosure, so the national standard does not protect the enclosure. Special requirements.
