Anti-explosion indicator light

Abstract

The invention provides an anti-explosion indicator light which comprises a casing, an LED lamp source, a battery and a wiring terminal. The LED lamp source, the battery and the wiring terminal are arranged in the casing; the LED lamp source is electrically connected with the battery; the battery is connected with the wiring terminal through a wire; the wiring terminal is connected with external alternating current through a wire; the casing comprises an upper casing body and a lower casing body; the upper casing body and the lower casing body can form an accommodating cavity for accommodating the LED lamp source, the battery and the wiring terminal; the upper casing body and the lower casing body are in contact connection; the connecting position between the upper casing body and the lower casing body is sealed through a sealing stripe; the accommodating cavity becomes a sealed accommodating cavity; and a contact mode between the upper casing body and the sealing stripe and a contact mode between the lower casing body and the sealing stripe are face-to-face contact modes. The anti-explosion indicator lamp can meet the using requirements in the anti-explosion, dustproof and purifying field.

Description

technical field [0001] The invention relates to the structural field of explosion-proof lamps, in particular to an explosion-proof indicator light. Background technique [0002] The fire indicator light, which is suitable for special instructions in fire emergency situations, is the most common tool in fire emergency. For example, the common safety exit indicator light is a kind of lamp that instructs people to go to a safe zone when other emergency states such as fire or power failure. When the AC power fails to supply power normally due to a fault, the indicator light can switch to the emergency state of the standby power supply within <1 second, always making the sign clear and clear, and effectively guiding personnel to evacuate safely. The fire emergency indicator light is suitable for public places such as factories, hotels, schools, and units to prepare for power failures as emergency lighting. [0003] In the prior art, the structure of the fire indicator light ...

Problems solved by technology

[0004] However, the above-mentioned fire indicator lights can only be applied to more conventional fields, but cannot meet the requirements for fields requiring explosion-proof, dust-proof and purified lighting such as chemical industry, medicine, biotechnology, electronics, food, military industry, petroleum, etc.

Because the general fire indicator lights have the risk of electric sparks leaking from the seams of the lamp housing at the moment when the light source is turned on and off, or the dust in the working environment enters the lamp housing from the seams, and then Potential safety hazards such as explosions
