LED (Light Emitting Diode) mine explosion-proof locomotive lamp

Abstract

The invention relates to an LED (Light Emitting Diode) mine explosion-proof locomotive lamp, which comprises a front cover and a lamp tube. The front cover is connected with one end of the lamp tube through threads. The other end of the lamp tube is connected with a rear cover through threads. A front cover transparent mesh enclosure assembly, the lamp tube and the rear cover form a closed chamber in a surrounding manner. The LED mine explosion-proof locomotive lamp is characterized in that the lamp tube is provided with a first step surface and a second step surface; a light source device fixing plate, LEDs, a light reflecting plate, a light transmitting mirror and a circuit aluminum substrate are arranged on one side surface, facing to the front cover, of a light source fixing plate; a lamp holder inner chamber wiring board is connected with bolts for fixing a power driving device in a positioned manner; one side of the wiring board resists against the second step surface, and other side of the wiring board resists against a clamping ring; a wire incoming hole is formed in one end of the lamp tube, and a power line is connected with the power driving device of the wiring board through a wire incoming hole in a cable clamping and leading-in device. The LED mine explosion-proof locomotive lamp has the advantages that since the LEDs are used as illuminating light sources, the lamp is safe and reliable; since a thread explosion-proof and plane seam allowance explosion-proof design is adopted, and bolts capable of preventing a shell thread explosion-proof connection from getting loose are arranged as safety measures after the front cover and the lamp tube are fastened in an explosion-proof manner through the threads, the entire lamp has the effects of being very good waterproof, dustproof, explosion-proof, anti-seismic and safe.

Description

technical field [0001] The invention relates to an LED explosion-proof locomotive light for mining. Background technique [0002] Underground coal mines may be filled with explosive dust or gas, so the lamps and lanterns used in such explosive hazardous environments must have explosion-proof and explosion-proof effects. The principle of explosion-proof and explosion-proof is to seal the internal wiring, electrical components, and light-emitting elements of the lamps , so that it cannot be in contact with explosive gas or dust. At the same time, even if there is an explosive medium inside the lamp, and the components inside the lamp detonate it, the airtight shell must also ensure that the internal explosion will not be transmitted to the outside world. Currently, the lamps used in underground coal mines Most of them are traditional light sources such as incandescent lamp power supply. This kind of light source is characterized by high heat generation, easy damage, high power...

[0002] Underground coal mines may be filled with explosive dust or gas, so the lamps and lanterns used in such explosive hazardous environments must have explosion-proof and explosion-proof effects. The principle of explosion-proof and explosion-proof is to seal the internal wiring, electrical components, and light-emitting elements of the lamps , so that it cannot be in contact with explosive gas or dust. At the same time, even if there is an explosive medium inside the lamp, and the components inside the lamp detonate it, the airtight shell must also ensure that the internal explosion will not be transmitted to the outside world. Currently, the lamps used in underground coal mines Most of them are traditional light sources such as incandescent lamp power supply. This kind of light source is characterized by high heat generation, easy damage, high power consumption, and unsafe use. Moreover, when the light source is used for a long time, the ambient temperature will be high. It is easy to cause an explosion. At the same time, the traditional light source contains toxic substances such as mercury, which has a short service life and high energy consumption. This lamp is a new type of high-power, wide-circuit design. The light source is mercury-free, non-toxic, and pollution-free. More than 50%, the long-term use temperature is lower than 50°C, which is a safe, environmentally friendly and energy-saving product
