With the improvement of living standards, the safe environment for production and living has been increasingly valued by people. Explosion-proof lighting is an indispensable tool for people to carry out various operations, and their safety performance is widely recognized by people. Explosion-proof lamps and lanterns, refers to the place used for dust and flammable gas more, the environment is more sensitive to the place, can prevent the lamp in the working process of sparks and flammable materials in contact, so as to achieve the purpose of explosion-proof lamps.

LED explosion-proof lamp is a type of explosion-proof lamp. Its principle is the same as that of explosion-proof lamp except that the light source is LED light source. It is a specific measure taken to prevent the ignition of surrounding explosive mixtures such as explosive gas environment, explosive dust environment, gas gas, etc. Light fixtures.

Technical advantages

As the LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, small heat generation, small power consumption, operating voltage is safe and low voltage, long service life, etc. Therefore, high-power white LED explosion-proof lamps are a very ideal electric light source.

LED explosion-proof light, patent area sealing technology; more in line with national explosion-proof new technology. The utility model relates to an electrical equipment used in a special industry, which mainly solves the lighting problem. The lamp housing includes a lamp shell, a lamp shade arranged at the front end of the lamp shell, a luminous body and a battery arranged inside the lamp shell, and a switch arranged on the surface of the lamp shell. :

The luminous body is a high-power LED module, and a wide voltage input driving circuit is arranged between the luminous body and the battery; the wide voltage input driving circuit includes a constant current chip, the constant current chip and the battery constitute a power module, and the LED module is connected to the constant On the current chip, the power module and the LED module are sealed together; ultrasonic welding is performed between the lamp housing and the lamp housing.

It uses the characteristics of low heat generation LED to achieve intrinsically safe explosion-proof, and the LED light source has a long life; the LED maintains a constant brightness at the end of full charge and discharge; a heat sink is arranged on the lamp housing to achieve effective heat dissipation of the LED module. It ensures the stability of use and is applicable to various industries such as coal mines, petroleum, railways, and flood prevention.

It is applicable to hazardous areas in Zone 1, Zone 2 and Class IIA, IIB, and IIC explosive gas atmospheres.

Use caution

1. Check whether the transparent parts have been affected by the foreign material, whether the protection net has loosened, detached or corroded. If so, use should be stopped and repaired and replaced in time.

2. Regularly eliminate dust and dirt on the explosion-proof lamp housing to improve the efficacy and heat dissipation performance of the lamp. The cleaning method can be based on the protection capability of the lamp housing, using water spray (over the shade on the lamp) or using a damp cloth. When cleaning with water spray, the power should be cut off. Never use a dry cloth to scrub the plastic housing (transparent parts) of the lamp to prevent static electricity.

3. If there is accumulated water in the cavity of the lamp used in the humid environment, it shall be promptly removed and the sealing parts shall be replaced to ensure the protective performance of the enclosure.

4. The light source should be turned off in a timely manner to notify the replacement of the light source so as to prevent the ballast and other electrical components from being in an abnormal state for a long period of time because the light source cannot be started.

5. After opening the cover, check whether the flameproof joint surface is intact, whether the rubber seal is hardened or becomes sticky, whether the wire insulation layer is green and carbonized, and whether the insulation and electrical components are deformed and burned. If these problems are found, they should be promptly repaired and replaced.

6. When you open the lamp cover, you should press the warning card to open the cover after turning off the power.

7. Before applying the cover, apply a damp cloth (not excessively wet) to light the light and transparent parts of the light fixture to increase the efficacy of the light fixture. A layer of 204-1 displacement rust preventive oil should be applied thinly on the flameproof joint surface. When the lid is closed, attention should be paid to whether the sealing ring plays a sealing role in the original position.

8. The sealed part of the lamp should not be frequently disassembled and opened. Patent zone road sealing technology; more in line with national explosion-proof new technology.
