Gas stations are flammable and explosive places, and the safety requirements are particularly strict. The selection of lamps and lanterns must meet the standards. At present, the lamps used in gas stations are gradually being replaced by LED gas station lights. So what are its advantages? What is its safety classification? Below, the editor will give you a brief introduction.

Advantages of LED gas station lights:

Because LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, low calorific value, low power consumption, safe and low operating voltage, long service life, etc., and low energy consumption; therefore, high-power white light LEDs are explosion-proof lamps, especially An ideal electric light source for portable explosion-proof lamps.

LED explosion-proof light, patent area road sealing technology: more in line with the national explosion-proof new technology. The utility model belongs to a kind of electrical equipment used in special industries, which mainly solves the lighting problem.

It is characterized in that: the illuminator is a high-power LED module, and a wide voltage input drive circuit is arranged between the illuminator and the battery: the wide voltage input drive circuit includes a constant current chip, the constant current chip and the battery form a power module, and the LED module The group is connected to the constant current chip, and the power module and the LED module are glued together: ultrasonic welding is used between the lampshade and the lamp housing.

It takes advantage of the low calorific value of 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 the battery charge and discharge; a heat dissipation device is installed on the lamp housing to achieve effective heat dissipation of the LED module. , to ensure the stability of use, suitable for lighting in coal mines, petroleum, railways, flood control and other industries.

Safety level classification of LED gas station lights:

1. Class 0 lamps: lamps without ground wire, lamps that rely on basic insulation as protection against electric shock, which means that the accessible conductive parts of the lamps are not connected to the protective conductor in the fixed wiring of the facility. It just depends on the environment.

2. Class I lamps: lamps with ground wires, the protection against electric shock of lamps not only relies on basic insulation, but also includes additional safety measures, that is, connecting accessible conductive parts to the protective grounding conductor in the fixed line of the facility, so that the Accessible conductive parts shall not become live in the event of failure of basic insulation.

3. Class II lamps: lamps without ground wire, the protection against electric shock is not only based on basic insulation, but also has additional safety measures, such as double insulation or reinforcement, but there is no protective grounding measures or depends on installation conditions.

4. Class III lamps: The protection against electric shock depends on the power supply voltage being a safe extra-low voltage, and will not produce lamps with a voltage higher than SELV.

　　The above is the introduction of the editor, I hope it can deepen your impression of .
