led mining explosion-proof locomotive lights

Abstract

LED mining explosion-proof locomotive light, including a front cover and a lamp tube, the front cover is threaded to one end of the lamp tube, the other end of the lamp tube is threaded to the rear cover, the front cover transparent net cover assembly, the lamp tube, the rear The cover forms a closed cavity, which is characterized in that: the lamp tube is provided with a first stepped surface and a second stepped surface, and the side of the light source fixing plate facing the front cover is provided with a light source device fixing plate, LED light-emitting diodes, light reflection plate, light-transmitting mirror, circuit aluminum substrate, the wiring board in the inner cavity of the lamp holder and the power drive device are positioned and connected by fixing bolts, one side of the wiring board is against the second step surface, and the other side of the wiring board is against the collar; There is a wire inlet hole at one end of the lamp tube, and the power wire is connected to the wiring board power drive device through the wire inlet hole of the cable clamping introduction device. This invention uses LED as the lighting source, which is safe and reliable, and adopts thread explosion-proof and plane seam explosion-proof design. , After the front cover and the lamp tube are fastened by the explosion-proof thread, the anti-loosening bolts connected by the shell thread explosion-proof are provided as a safety measure. It makes the whole lamp have a good waterproof and dustproof, explosion-proof and shock-proof safety effect.

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
