Mining flame-proof and intrinsically safe LED emergency lamp powered by lithium battery

Abstract

The invention discloses a mining flame-proof and intrinsically safe LED emergency lamp powered by a lithium battery. The LED emergency lamp comprises a flame-proof shell and a support plate, wherein the support plate is mounted in the flame-proof shell and fixed through perforated fixing blocks, a first flame-proof chamber provided with a built-in electric control board and a second flame-proof chamber provided with one built-in lithium battery are arranged on one side of the support board, the top of the first flame-proof chamber is provided with first flame-proof wire outgoing holes, a second flame-proof wire outgoing hole is arranged in the top of the second flame-proof chamber, and the first flame-proof chamber and the second flame-proof chamber are connected through a chamber-penetrating terminal; a first flame-proof chamber circuit embedded on the electric control board is arranged in the first flame-proof chamber, and a second flame-proof circuit is arranged in the second flame-proof chamber; an LED lamp housing and an LED lamp body inside the LED lamp housing are arranged on the other side of the support plate. The LED emergency lamp is powered by the lithium battery, and is long in emergency lighting time, less in used space, cost saving, compact in structure, small in size and quite convenient to transport and mount.

Description

technical field [0001] The invention relates to an LED emergency light, in particular to a mining explosion-proof and intrinsically safe LED emergency light powered by a lithium battery, which belongs to the technical field of coal mine equipment. Background technique [0002] LED lamp is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. It has been used in various industries. However, the lighting fixtures used in underground coal mine roadways today have a single structure, old, energy-consuming, imperfect functions, and short service life. They do not have emergency backup lighting after power failure in function, which makes large It is very inconvenient after a power outage in the electric room, signal room, etc., and it also poses hidden dangers to safety. [0003] At present, among the various lamps used in underground coal mines in my country, there is no LED emergency lighting p...
