[0014] The following is a description of the embodiments and appendices. Figures 1-5 The technical solution of this utility model will be further described below.

[0015] Example 1 A mine-use explosion-proof LED bracket light includes: a bracket 1, a housing 2, a light source assembly 3, and a power supply assembly 4. One end of the bracket 1 is rotatably connected to one end of the housing 2 via a first pivot 11, and the other end of the housing 2 is rotatably connected to the other end of the housing 2 via a second pivot 12. An angle orientation disk 13 is provided on the second pivot 12, and the angle orientation disk 13 includes two rotatably interlocking convex disks 14. The housing 2 includes an interconnected light source cavity 21 and a power supply cavity 22. The light source assembly 3 is disposed in the light source cavity 21, and the power supply assembly 4 is disposed in the power supply cavity 22 and supplies power to the light source assembly 3.

[0016] like Figures 1-5 As shown, the working principle of this utility model is as follows: The bracket 1 serves as the mounting carrier, with its two ends rotatably connected to the housing 2 via a first rotating shaft 11 and a second rotating shaft 12, forming a rotatable connection structure. The angle-oriented disk 13 on the second rotating shaft 12 consists of two rotatably interlocking convex disks 14, and the relative rotation of the convex disks enables the angle adjustment and positioning of the housing 2 and the bracket 1. The housing 2 has an interconnected light source cavity 21 and a power supply cavity 22. The light source assembly 3 is installed in the light source cavity 21, and the power supply assembly 4 is installed in the power supply cavity 22. The two are electrically connected through the communication structure between the cavities, and the power supply assembly 4 provides a stable power supply to the light source assembly 3.

[0017] During operation, the illumination direction of the light source assembly 3 can be adjusted by rotating the housing 2 around the first rotating shaft 11 and the second rotating shaft 12. The two convex disks 14 of the angle orientation disk 13 interlock with each other and lock in position after rotating to the target angle to ensure stable illumination direction. The area to be illuminated is covered by the light source assembly 3, and the power supply assembly 4 continuously provides power support. The overall structure of the housing 2 forms a closed space, meeting the explosion-proof safety requirements of underground mining.

[0018] With the cooperation of rotating shaft 11, rotating shaft 2 12 and angle orientation plate 13, the lighting fixture can flexibly adjust the illumination angle within the range of 0°-180°, which solves the problem of blind spots caused by the fixed angle of traditional lighting fixtures. It can adapt to complex operation scenarios such as underground tunneling faces and roadway corners, and ensure sufficient lighting in key areas. The light source component 3 and the power supply component 4 are placed in different chambers, and can be repaired in a targeted manner in case of failure. For example, if the light source or power supply module is replaced, the entire lighting fixture does not need to be disassembled, which reduces the difficulty of underground maintenance.

[0019] As a further preferred embodiment, the left pivot 11 is provided with nuts 111 located at both ends of the bracket 1 and the box 2, and the right pivot 12 is provided with nuts 121 located at both ends of the bracket 1 and the box 2. Each set of convex discs 14 is provided with fan-shaped protrusions 141 spaced in an annular pattern, and each set of fan-shaped protrusions 141 is provided with a slot 142 between them.

[0020] Nut 111 of the left rotating shaft 11 and nut 121 of the right rotating shaft 2 12 are located at the two ends of the bracket 1 and the box 2, respectively. Tightening the nuts can enhance the friction between the rotating shaft and the bracket and the box, preventing unauthorized rotation. The fan-shaped protrusions 141 and the slots 142 arranged in a ring on the convex plate 14 of the angle orientation plate 13 can be engaged into the slots of the other convex plate when the two convex plates rotate relative to each other, forming a mechanical positioning.

[0021] As a further preferred embodiment, the housing 2 includes a shell 23, a rear cover 24, and a front cover 25. The light source cavity 21 is located at the front end of the shell 23, and the power supply cavity 22 is located at the rear end of the shell 23. A guide hole 26 connects the light source cavity 21 and the power supply cavity 22. A lower glass plate cavity 211 is provided on the front side of the light source cavity 21. A glass upper cavity 251 with a shape matching the lower glass plate cavity 211 is provided at the lower end of the front cover 25. A sealing strip 252 is provided on the inner edge of the glass upper cavity 251. An annular groove 231 is provided at the rear end of the shell 23. A sealing block 241 is provided on the rear cover 24 and matched to be inserted into the annular groove 231. A second sealing strip 232 is provided inside the annular groove 231. The shell 23, the rear cover 24, and the front cover 25 are all made of cast steel.

[0022] The housing 23, rear cover 24, and front cover 25 are all made of cast steel, whose high strength characteristics can withstand the high pressure and high temperature generated by an accidental internal explosion; the annular groove 231 at the rear end of the housing and the sealing block 241 of the rear cover form a precision mating surface, and the explosion-proof gap of the mating surface meets the explosion-proof standard, which can prevent the flame from spreading to the outside and meet the explosion-proof "d" type requirements.

[0023] The sealing strip 252 of the upper cavity 251 on the glass plate and the sealing strip 232 of the annular groove 231 fill the gaps between the front cover and the housing and the rear cover and the housing, respectively, to prevent dust and moisture from entering the cavity; the light source cavity 21 and the power supply cavity 22 are connected through the guide hole 26, which facilitates wiring and does not damage the overall sealing performance.

[0024] The sealing strip works in conjunction with the enclosed structure to achieve an IP66 protection rating for the enclosure, which can withstand harsh environments such as high dust and water spray in the mine, and prevent internal components from failing due to contamination or moisture.

[0025] As a further preferred embodiment, the light source assembly 3 includes a glass plate 31, a reflector 32, a lens plate 33, and a light source plate 34. The light source plate 34 is fixed to the bottom of the light source cavity 21, the lens plate 33 is fixed to the upper end of the light source plate 34, the outer side of the reflector 32 is fixed to the upper end of the lens plate 33, the lens 331 on the lens plate 33 is located in the hollow area of ​​the reflector 32, and the lower end of the glass plate 31 is installed in the lower cavity 211 of the glass plate.

[0026] The light source plate 34 generates illumination light; the lens 331 on the surface of the lens plate 33 can refract light and control the divergence angle of the light, transforming the point light source of the LED into a surface light source, making the light distribution more uniform and reducing glare; the reflector 32 is located above the lens plate 33, and its multi-faceted reflection structure can reflect the scattered light that is not effectively utilized by the lens to the target area, realizing secondary light distribution and expanding the illumination range; the glass plate 31 is installed in the lower cavity 211 of the glass plate, covering the front end of the light source cavity 21, which not only ensures high light transmittance, but also physically isolates the external environment, protecting the internal lens, reflector and light source plate from dust and mechanical impact.

[0027] As a further preferred embodiment, the light source board 34 is an LED cold light source. LED light sources have low energy consumption, which can reduce the power supply load in the mine; and they do not have the problem of filament damage, have a long service life, and reduce the replacement frequency and maintenance costs.

[0028] As a further preferred embodiment, the driving input voltage of the light source board 34 is AC40V~260V. Because multiple devices are connected simultaneously underground, voltage drops often occur. The wide voltage range of 40V~260V ensures that the lamps can still emit light stably during voltage fluctuations, preventing sudden outages from affecting operations.

[0029] As a further preferred embodiment, the power supply assembly 4 includes a power module 41 and a terminal block 42. The power module 41 is fixed in the power cavity 22 by screws, and the terminal block 42 is fixed on the power module 41. The rear end of the housing 2 is provided with two sets of cable holes that communicate with the power cavity 22, and a cable clamping nut 27 is installed in the cable hole.

[0030] The power module 41 provides a stable voltage to the light source board 34; the terminal block 42 facilitates the quick connection of external cables to the power module and simplifies the wiring process; the cable clamping nut 27 is installed in the cable hole at the rear of the box. By tightening the nut, the rubber sealing ring is deformed and tightly wraps the outer periphery of the cable to achieve a seal between the cable and the hole wall.

[0031] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
