LED explosion-proof lamp
LED explosion-proof lamp is a kind of explosion-proof lamp, the principle is the same as that of explosion-proof lamp, except that the light source is LED light source, which refers to various specific measures taken to prevent ignition of surrounding explosive mixture such as explosive gas environment, explosive dust environment, gas gas, etc. Measures for the luminaire. LED explosion-proof lamps are currently the most energy-saving explosion-proof lamps, widely used in oil fields - power plants - chemical plants - oil - troops.

Introduction editor
One of the most important explosion-proof principles of LED explosion-proof luminaires is to limit the temperature of the surface of the casing in contact with explosive gases, explosive dust, the surface of components or the surface of electronic components, and to limit the temperature of the electrical contact surface below its minimum ignition temperature or ignition temperature. . For LED explosion-proof lamps used outdoors, waterproof drives are required. The led explosion-proof lamp used at the gas station needs to be shockproof!
Technical advantage editing
Because LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, low heat generation, low power consumption, safe voltage and low voltage, long service life, etc., and low energy consumption; therefore, high-power white LED is an explosion-proof lamp, especially An ideal electric light source for portable explosion-proof lamps.
LED explosion-proof lamp, patent zone road sealing technology; more in line with national explosion-proof new technology. The utility model relates to an electrical device used in a special industry, which mainly solves the lighting problem, and comprises a lamp housing, a lamp cover disposed at the front end of the lamp housing, an illuminant and a battery disposed inside the lamp housing, and a switch disposed on the surface of the lamp housing, wherein the switch is characterized in that The illuminant is a high-power LED module, and a wide voltage input driving circuit is arranged between the illuminant and the battery; the wide voltage input driving circuit comprises a constant current chip, the constant current chip and the battery form a power module, and the LED module is connected On the constant current chip, the power module and the LED module are glued together; ultrasonic welding is performed between the lamp cover and the lamp housing.
It utilizes the characteristics of low heat generation of LED to achieve intrinsically safe explosion-proof, and the LED light source has a long service life; the battery maintains constant brightness at the end of full charge and discharge; the heat dissipation device is arranged on the lamp housing to achieve effective heat dissipation of the LED module It guarantees the stability of use and is suitable for lighting in various industries such as coal mine, petroleum, railway and flood control.
Applicable to hazardous areas in Zone 1, Zone 2, IIA, IIB, IIC explosive gas environment.
Applicable to hazardous areas in Zone 0 and Zone 21, IA, IB, IC explosive gas environment.
Example
LED explosion-proof platform lights are suitable for fixed lighting in petrochemical plants, oil platforms, gas stations, oil pumping houses, transfer stations, oil fields and other inflammable and explosive places.
Explosion-proof mark: Exd II BT6, Exd II CT4, Gb Protection grade: IP66, IP67.
Performance characteristics:
■The light distribution of the lamp is unique, the illumination range is uniform, and the illumination angle is up to 220 degrees. The light is fully utilized; the light is soft and glare-free, which will not cause eye fatigue of the operator and improve work efficiency.
■The light source adopts the world's brightest LED, and the power consumption is only 40% of the metal halide lamp.
■ All key components of the power supply are selected by the world's top brands, which are efficient and stable.
■Using a unique heat dissipation structure, the heat transfer heat conduction method is used to accelerate the heat conduction, which effectively ensures the efficient heat dissipation of the LED, so that the LED life can reach 100,000 hours.
■ The highest explosion-proof grade of explosion-proof type can be used in flammable and explosive places in various industries.
■ Can be connected in parallel, eliminating the need for junction boxes and installation costs.
■The shell is made of high-tech surface spraying technology, which is wear-resistant, corrosion-resistant, waterproof and dustproof, and is suitable for various harsh environments.
■ When the led explosion-proof lamp is used as a floodlight: add a condenser cover to the surface of the light source to increase the illumination of the floodlight.
■ led explosion-proof lamp used in winery explosion-proof lamp: should use zone road seal design; explosion-proof intrinsic safety type; protection grade IP65, anti-corrosion grade WF1, to achieve waterproof, dustproof, explosion-proof.
■ led explosion-proof lamp for oil field explosion-proof lamp use: should use anti-fall ring design; to achieve vibration of the oil field derrick, in order to prevent the lamp from falling off because of the bolt, but not protected by the fall ring
