[0002] Explosion-proof vehicles are also called blasting equipment transport vehicles. With the improvement of my country's industrialization, the requirements for safety and environmental protection are getting higher and higher. Explosion-proof vehicles have been separated from the original flatbed transportation and changed to van transportation. The series of blasting equipment transport vehicles developed today are developed and produced according to the specifications of relevant state ministries and commissions for the transportation of blasting equipment and the requirements of users. Various vehicles used in mines containing explosive and dangerous gases and dust (such as methane, coal dust, etc.) must use explosion-proof lighting fixtures. LED lamps are an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then the chip and circuit board are connected with silver wire or gold wire. It is sealed with epoxy resin around to protect the internal core wire, and finally the shell is installed, so the LED lamp has good seismic resistance.
[0003] The various types of explosion-proof vehicle lighting fixtures currently used have defects such as: the lights have no light distribution and the lighting direction cannot be adjusted. Summary of the invention
[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide an explosion-proof vehicle LED low and high beam lighting lamp with adjustable angles.
[0005] The above-mentioned object of the present invention is achieved through the following technical solutions:
[0006] An explosion-proof vehicle LED high-beam and low-beam lighting lamp, comprising a lighting lamp housing, a front cover connected to the front section of the lighting lamp housing by screws, a transparent tempered glass layer provided on the front cover, a light source assembly provided in the lighting lamp housing, the light source assembly facing the tempered glass layer, a middle cover connected to the rear end of the lighting lamp housing by screws, a wiring terminal assembly provided in the middle cover, the wiring terminal assembly being electrically connected to the light source assembly, a rear cover connected to the end of the middle cover away from the lighting lamp housing by screws, a cable introduction device provided on the rear cover;
[0007] The light source assembly includes a vertical plate arranged on the lighting lamp housing, a direction adjustment motor is arranged on the side of the vertical plate facing the tempered glass layer, an aluminum-based circuit board is arranged on the direction adjustment motor, a light distribution lens is arranged on the aluminum-based circuit board, and a high-power SMD LED lamp bead is arranged in the light distribution lens.
[0008] By adopting the above technical solution, the user can adjust the angle of the light distribution lens through the steering motor, and the heat on the light-transmitting glasses can be dissipated through the aluminum-based circuit board, and high-brightness light can be emitted through high-power SMD LED lamp beads.

[0010] By adopting the above technical solution, the high beam lens and the low beam lens can emit low beam and high beam. Because the thickness of the lens is different, the heat emitted is different. The high beam lens and the low beam lens of different temperatures can be heat-conducted through the heat conduction ring, and the heat is dissipated through the heat sink.

When the terminal block becomes loose, the magnetic screw and the lighting lamp housing become loose, and no longer attract the powered adsorption block. The powered adsorption block falls off from the electrical placement groove, so that the user can be informed of the looseness or fall-off of the terminal block through other equipment such as the alarm, thereby increasing the safety of the lighting lamp.
[0015] In a preferred example, the present invention can be further configured as follows: the cable introduction device includes a connector embedded in the back cover, the connector is circumferentially provided with an elastic layer, a first fixing frame is provided between the elastic layer and the back cover, and a sealing ring is provided between the back cover and the first fixing frame.
[0016] By adopting the above technical solution, the gap between the connector and the back cover is filled with the elastic layer, thereby increasing the connection stability between the connector and the back cover. The first fixing frame further increases the firmness of the connection between the connector and the back cover, and the sealing ring increases the sealing of the back cover at the connector, thereby reducing the infiltration of rainwater or other liquids.
[0017] In a preferred example, the present invention can be further configured as follows: an elastic protrusion is provided at one end of the elastic layer inserted into the rear cover.

The adjustment pad can adjust the slight adjustment of the window pressure plate to adjust the angle of the tempered glass layer.
[0021] In a preferred example, the present invention can be further configured as follows: a protection frame is connected to the front cover by bolts.
[0022] By adopting the above technical solution, the front cover can be protected by the protective frame, the damage to the front cover can be reduced, and the anti-collision performance of the lighting lamp can be improved.
[0023] In summary, the present invention includes at least one of the following beneficial technical effects:
[0024] 1. The user can adjust the angle of the light distribution lens through the steering motor, and the heat of the high-power SMD LED lamp beads can be dissipated through the aluminum-based circuit board, and the high-brightness light can be emitted through the high-power SMD LED lamp beads. It is equipped with a high-beam lens and a low-beam lens, which can emit low-beam and high-beam lights. The temperature of the high-beam lens and the low-beam lens with different temperatures can be conducted through the heat conduction ring, and then the heat is transferred to the heat sink to dissipate the heat;
[0025] 2. Compensate for the light beam deviation caused by manufacturing and assembly errors, so that the light can better illuminate the road ahead;
[0026] 3. The magnetic screw can attract the energized adsorption block in the electrical placement slot. The electrical placement slot and the energized adsorption block can form a simple switch and connect other devices such as alarms in series. When the terminal block becomes loose, the magnetic screw and the lighting housing become loose, and no longer attract the energized adsorption block. The energized adsorption block falls off from the electrical placement slot, so that the user can be informed of the looseness or fall-off of the terminal block through other devices such as alarms, thereby increasing the safety of the lighting.
