LED lighting device and its explosion-proof power supply

Abstract

The invention relates to an LED lighting device which comprises an anti-explosion power supply. The anti-explosion power supply comprises a short-circuit protection circuit, an electromagnetic compatibility and electromagnetic radiation suppression circuit, a high-voltage rectification filter circuit, a high-low voltage isolation module, a constant-current module, a filter circuit and a constant-voltage circuit, wherein the lightning strike protection voltage of the short-circuit protection circuit reaches 4 kilovolts, and the short-circuit protection circuit, the electromagnetic compatibility and electromagnetic radiation suppression circuit, the high-voltage rectification filter circuit, the high-low voltage isolation module, the constant-current module, the filter circuit and the constant-voltage circuit are connected in sequence. An input end of the short-circuit protection circuit is connected with mains supply alternating current. The constant-voltage circuit is provided with a plurality of output ends, and each output end outputs 16.5-volt constant voltage and outputs 320-milliampere constant current. Due to the fact that the LED lighting device is provided with the anti-explosion power supply, the LED lighting device ensures that LED lamp beads work in an environment with stable and safe voltage and stable and safe current, avoids overheating of the LED lamp beads, and further avoids burst of the LED lamp beads, and can be applied to various flammable and combustible industries.

Description

technical field [0001] The invention relates to a power supply module, in particular to an LED lighting device and an explosion-proof power supply thereof. Background technique [0002] LED lighting devices are widely used in various lighting fields. However, the current LED lighting devices generally have the problem of poor heat dissipation and easy overheating and bursting. In some flammable and explosive industries, such as coal mines (underground central substation, mining area substation, winch room, water pump room, main transportation road, fully mechanized mining face, belt machine head and coal discharge point requirements, etc.) , Petroleum, petrochemical (areas: areas with petrochemical installations, indoor equipment areas such as pump rooms, daily maintenance and emergency lighting, etc.), gas stations and other explosive hazardous places in Zone 0, Zone 1 and Zone 2, any tiny sparks will May cause fire or explosion. Contents of the invention [0003] The ...
