Abstract

An LED explosion-proof emergency lamp for ship is an emergency illumination lamp which is used for various environments with explosive gas. A mechanical structure of the LED explosion-proof emergency lamp comprises two parts, namely a box body assembly and a head holder. In the explosion-proof structure, the structures such as encapsulation type explosion-proofing structure, planar explosion-proofing structure and screw thread explosion-proofing structure are adopted for ensuring the personnel safety of the person in the explosive gas operation environment. A frosting form is adopted at the periphery of a center of the protective glass of an optical system so the distribution of the light illumination is uniform and reasonable. A circuit system is composed of the following components: an LED, a switching power supply, a battery pack, a state display circuit, a power shutdown detection circuit, an emergency switching circuit, a discharging terminating circuit, a driving circuit, etc., thereby realizing four operation states of the emergency lamp, namely a charging state, a discharging state, a switched-off state and a displaying state. As the LED light source is adopted, the LED explosion-proof emergency lamp for ship has the following advantages: settling the problems of large energy consumption, inferior shock resistance, short emergency illumination time, and short service life of the bulb in an incandescent lamp of the prior-art explosion-proof emergency lamp; complying with time currents of energy saving and emission reduction and obtaining excellent social benefit.
