Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to a brightness-adjustable explosion-proof LED lighting lamp for mining. Background Technology

[0002] Explosion-proof LED tunnel induction lights for mining are lighting fixtures specifically designed for hazardous environments such as underground coal mines. When in operation, the microwave induction board emits and receives microwave signals. When a person or object moves within the sensing range, it causes reflection and changes in the microwave signal. After detecting this change, the induction board transmits the signal to the controller. When a person approaches, the power increases and the brightness increases; when the person moves away, the power decreases and the brightness decreases.

[0003] When using LED lighting, the lights are usually hung and installed on both sides of the passageway inside the mine. After installation, the lighting area is usually fixed. When the lights are turned on, there may be some ineffective illumination areas, resulting in low light utilization efficiency and certain limitations. Utility Model Content

[0004] The purpose of this invention is to address the problem that the lighting area of ​​a lighting lamp is usually fixed after installation, and there may be some ineffective illumination areas after the entire lighting lamp is turned on, resulting in low light utilization efficiency and certain limitations when the lighting lamp is used. Therefore, this invention proposes a brightness-adjustable explosion-proof LED lighting lamp for mining.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a brightness-adjustable explosion-proof LED lighting lamp for mining, comprising a housing, a microwave induction plate disposed inside the housing, a substrate disposed inside the housing, a protective frame and explosion-proof glass fixedly connected to one side of the housing, a wiring conduit fixedly connected to one end of the housing, and an auxiliary device disposed on the outer surface of the housing that can reflect the light emitted by the substrate.

[0006] The effects achieved by the above components are as follows: When using the lighting lamp, the power supply line of the lighting lamp is connected to the lighting lamp through the terminal block, and the housing is suspended and fixed on the side wall of the inner channel of the frame. When the lighting lamp is working, the microwave induction board emits and receives microwave signals. When a person or object moves within the sensing range, it will cause the microwave signal to be reflected and changed. After the induction board detects this change, it transmits the signal to the controller, which increases the power of the substrate and emits brighter light. After the person moves away, the power of the substrate decreases and the brightness becomes lower. The inner substrate can be protected by the protective frame and the explosion-proof glass on the outside.

[0007] Preferably, the auxiliary device includes a grooved rod and a sliding rod. The grooved rod is fixed to the top of the housing. An L-shaped groove is formed inside the grooved rod. A first spring and a locking block are provided at the bottom of the inner wall of the sliding rod. The locking block slides at the bottom of the inner wall of the sliding rod. The two ends of the first spring are fixedly connected to one end of the locking block and one side of the inner wall of the sliding rod, respectively. A cylinder is fixedly connected to one end of the sliding rod. A rotating rod is rotatably connected to the inner wall of the cylinder. A round rod is slidably connected to one side of the rotating rod. A pressure block is fixedly connected to one end of the round rod. A second spring is sleeved on the surface of the round rod. The two ends of the second spring are fixedly connected to one side of the rotating rod and one side of the pressure block, respectively (an L-shaped bracket is provided on the surface of the rotating rod, through which the round rod slides. The two ends of the spring are fixedly connected to the L-shaped bracket and the pressure block, respectively). A connecting rod is fixedly connected to the bottom of the rotating rod. A reflective component is provided on the surface of the connecting rod. The reflective assembly includes a reflector, a connecting rod consisting of an arc-shaped block, a spherical block disposed inside the arc-shaped block, and a rod body on one side of the spherical block, with the reflector fixedly connected to the end of the connecting rod away from the round rod.

[0008] The aforementioned components achieve the following effects: When using LED lighting, pressing the locking block at the bottom of the slide rod controls the block to slide along the bottom of the inner wall of the slide rod and compress the first spring, retracting it into the slide rod. Then, the slide rod is inserted vertically downwards into the L-shaped groove of the slotted rod. After the bottom of the slide rod contacts the bottom of the inner wall of the L-shaped groove, the first spring returns to its original state, pushing the locking block outwards, causing the locking block and the bottom of the slide rod to lock inside the L-shaped groove. At this point, pushing the slide rod controls the bottom of the slide rod to slide along the inner wall of the L-shaped groove. Adjusting the horizontal position of the slide rod on the outside of the housing and pulling the round rod controls... The pressure block is moved away from the outer surface of the cylinder. Pushing the rotating rod can control the rotation of the rotating rod inside the cylinder to adjust the angle of the reflector. After adjustment, releasing the second spring of the rod will push the pressure block to move towards the cylinder and press it against the outside of the cylinder to fix the position of the rotating rod inside the cylinder. Finally, the reflector can be rotated by rotating the reflector through the connecting rod to adjust the angle of the reflector on one side of the housing. The reflector can reflect the light emitted by the substrate and reflect the light from the lighting lamp that was directed at the ineffective illumination area to the effective area.

[0009] Preferably, a groove is provided on one side of the bottom end of the slide rod, and a push rod is fixedly connected to one side of the locking block, with the outer surface of the push rod sliding on the inner wall of the groove.

[0010] The effect achieved by the above components is that when it is necessary to remove the slide bar and reflector, the push rod can be pushed on one side of the bottom of the slide bar to control the locking block to move and retract into the slide bar, and then the slide bar can be pulled out upwards.

[0011] Preferably, a positioning block is fixedly connected to one side of the slide rod, and the outer surface of the positioning block is L-shaped.

[0012] The effect achieved by the above components is that after the bottom end of the slide rod is installed inside the groove rod, the L-shaped positioning block will fit against the outer surface of the groove rod. When the slide rod is pushed to move, the positioning block can further limit the angle between the slide rod and the groove rod, and prevent the angle of the slide rod from deviating.

[0013] Preferably, a support rod is fixedly connected to the outer surface of the slide rod, and the two ends of the support rod are respectively fixedly connected to the two ends of the slide rod.

[0014] The effect achieved by the above components is that by setting up support rods, the outer surface shape of the slide rod can be reinforced, thereby improving the structural stability of the outer surface of the slide rod.

[0015] Preferably, one end of the round rod is fixedly connected to a groove block, and the groove block has arc-shaped grooves on both sides.

[0016] The effect achieved by the above components is that by pinching the arc-shaped grooves on both sides of the groove block, it is easier to pull the groove block to control the movement of the round rod and the pressure block.

[0017] Preferably, auxiliary blocks are fixedly connected to both ends of the housing, and the outer surface of the auxiliary blocks is provided with grooves that are the same shape as the L-shaped groove inside the groove rod.

[0018] The effect achieved by the above components is that when installing the slide bar, the bottom end of the slide bar can also be installed on the auxiliary blocks on both sides of the housing to improve the reflection effect of light on the sides of the housing.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, by setting an auxiliary device, a specified number of sliding rods and reflectors are installed on the outside of the housing using grooved rods as needed. By moving the positions of the sliding rods and reflectors and adjusting the angle of the reflectors, the light from the lighting lamp directed at the ineffective lighting area can be reflected by the reflectors, thereby improving the light utilization efficiency and practicality of the lighting lamp.

[0028] Example 1, as Figure 1-2 As shown, a brightness-adjustable explosion-proof LED lighting lamp for mining includes a housing 1. A microwave induction plate and a substrate 5 are disposed inside the housing 1. A protective frame 3 and explosion-proof glass 4 are fixedly connected to one side of the housing 1. A wiring conduit 6 is fixedly connected to one end of the housing 1. An auxiliary device 2 is provided on the outer surface of the housing 1 to reflect the light emitted by the substrate 5. When the lighting lamp is in use, the power supply line of the lighting lamp is connected to the lighting lamp through the wiring conduit 6. The housing 1 is suspended and fixed on the side wall of the inner passage of the frame. When the lighting lamp is working, the microwave induction plate transmits and receives microwave signals. When a person or object moves within the sensing range, it causes reflection and change of the microwave signal. After detecting this change, the induction plate transmits the signal to the controller, increasing the power of the substrate 5 to emit brighter light. When the person moves away, the power of the substrate 5 decreases, and the brightness decreases. The protective frame 3 and the outer explosion-proof glass 4 protect the inner substrate 5.

[0029] Reference Figure 1-6As shown in this embodiment: the auxiliary device 2 includes a grooved rod 21 and a sliding rod 22. The grooved rod 21 is fixed to the top of the housing 1. An L-shaped groove 25 is opened inside the grooved rod 21. A first spring 24 and a locking block 23 are provided at the bottom of the inner wall of the sliding rod 22. The locking block 23 slides at the bottom of the inner wall of the sliding rod 22. The two ends of the first spring 24 are fixedly connected to one end of the locking block 23 and one side of the inner wall of the sliding rod 22, respectively. A cylinder 26 is fixedly connected to one end of the sliding rod 22. The inner wall of the cylinder 26 is rotatably connected to... A rotating rod 27 has a round rod 28 slidably connected to one side of it. A pressure block 29 is fixedly connected to one end of the round rod 28. A second spring 210 is fitted on the surface of the round rod 28. The two ends of the second spring 210 are fixedly connected to one side of the rotating rod 27 and one side of the pressure block 29, respectively. An L-shaped bracket is provided on the surface of the rotating rod, through which the round rod slides. The two ends of the spring are fixed to the pressure block of the L-shaped bracket, respectively. A connecting rod 211 is fixedly connected to the bottom end of the rotating rod 27. A reflective component is provided on the surface of the connecting rod 211. The reflector assembly includes a reflector 212, a connecting rod 211 consisting of an arc-shaped block, a spherical block disposed inside the arc-shaped block, and a rod on one side of the spherical block. The end of the connecting rod 211 away from the round rod 28 is fixedly connected to the reflector 212. By setting the reflector 212, when using LED lighting, the locking block 23 at the bottom of the slide rod 22 can be pressed to control the locking block 23 to slide on the bottom of the inner wall of the slide rod 22 and compress the first spring 24 to retract into the slide rod 22. Then, the slide rod 22 is vertically inserted into the slot rod. Inside the L-shaped groove 25 of 21, after the bottom end of the slide rod 22 contacts the bottom end of the inner wall of the L-shaped groove 25, the first spring 24 returns to its original state and pushes the locking block 23 to move outward, so that the locking block 23 and the bottom end of the slide rod 22 are locked inside the L-shaped groove 25. At this time, pushing the slide rod 22 can control the bottom end of the slide rod 22 to slide on the inner wall of the L-shaped groove 25. Adjusting the horizontal position of the slide rod 22 on the outside of the housing 1, pulling the round rod 28 controls the pressure block 29 to move away from the outer surface of the cylinder 26, and then pushing the rotating rod 27 can control the rotating rod 27 to move away from the outer surface of the cylinder 26. The internal rotation of the cylinder 26 adjusts the angle of the reflector 212. After adjustment, releasing the rod 28 and restoring the second spring 210 to its original state will push the pressure block 29 to move towards the cylinder 26 and press it against the outside of the cylinder 26 to fix the position of the rotating rod 27 inside the cylinder 26. Finally, the reflector 212 can be rotated by the connecting rod 211 to adjust the angle of the reflector 212 on one side of the housing 1. The reflector 212 can reflect the light emitted by the substrate 5, reflecting the light from the lighting lamp to the effective area instead of the ineffective area. By setting the auxiliary device 2, a specified number of sliding rods 22 and reflectors 212 are installed on the outside of the housing 1 with the help of the groove rod 21. By moving the position of the sliding rods 22 and the reflector 212 and adjusting the angle of the reflector 212, the reflector 212 can reflect the light from the lighting lamp to the ineffective area, improving the light utilization efficiency and practicality of the lighting lamp.

[0030] Reference Figure 2-5 As shown in this embodiment: a groove 213 is provided on one side of the bottom end of the slide rod 22, and a push rod 214 is fixedly connected to one side of the locking block 23. The outer surface of the push rod 214 slides on the inner wall of the groove 213. When it is necessary to remove the slide rod 22 and the reflector 212, the push rod 214 can be pushed on one side of the bottom end of the slide rod 22 to control the locking block 23 to move and retract into the slide rod 22, and then the slide rod 22 can be pulled out upwards. A positioning block 215 is fixedly connected to one side of the slide rod 22. The outer surface of the positioning block 215 is L-shaped. After the bottom end of the slide rod 22 is installed inside the groove rod 21, the L-shaped positioning block 215 will fit against the outer surface of the groove rod 21. When the slide rod 22 is pushed to move, the positioning block 215 can further limit the angle between the slide rod 22 and the groove rod 21, so as to prevent the angle of the slide rod 22 from deflecting.

[0031] Reference Figure 2-5 As shown in this embodiment: a support rod 216 is fixedly connected to the outer surface of the slide rod 22, and the two ends of the support rod 216 are fixedly connected to the two ends of the slide rod 22 respectively. By setting the support rod 216, the shape of the outer surface of the slide rod 22 can be reinforced, and the structural stability of the outer surface of the slide rod 22 can be improved. A groove block 217 is fixedly connected to one end of the round rod 28. The two sides of the groove block 217 are provided with arc-shaped grooves. By pinching the groove block 217 on both sides, it is easier to pull the groove block 217 to control the movement position of the round rod 28 and the pressure block 29. An auxiliary block 218 is fixedly connected to both ends of the housing 1 respectively. The outer surface of the auxiliary block 218 is provided with a groove with the same shape as the L-shaped groove 25 inside the groove rod 21. When installing the slide rod 22, the bottom end of the slide rod 22 can also be installed at the auxiliary blocks 218 on both sides of the housing 1 to improve the reflective effect of the bright side of the housing 1.

[0032] Working principle: When using the lighting lamp, connect the power supply line of the lighting lamp to the lighting lamp through the connecting pipe 6. Suspend and fix the housing 1 on the side wall of the inner channel of the frame. Press the locking block 23 at the bottom of the slide rod 22 to control the locking block 23 to slide on the bottom of the inner wall of the slide rod 22 and compress the first spring 24 to retract into the slide rod 22. Then, insert the slide rod 22 vertically downward into the L-shaped groove 25 of the slot rod 21. After the bottom end of the slide rod 22 contacts the bottom end of the inner wall of the L-shaped groove 25, the first spring 24 returns to its original state and pushes the locking block. Move 23 outwards so that the bottom of the locking block 23 and the sliding rod 22 are locked inside the L-shaped groove 25. At this time, pushing the sliding rod 22 can control the bottom of the sliding rod 22 to slide on the inner wall of the L-shaped groove 25. Adjust the horizontal position of the sliding rod 22 on the outside of the housing 1. Pull the round rod 28 to control the pressure block 29 away from the outer surface of the cylinder 26. Then push the rotating rod 27 to control the rotating rod 27 to rotate inside the cylinder 26 to adjust the angle of the reflector 212. After the adjustment is completed, release the round rod 28 and the second spring 210 to restore the original state. The pressure block 29 will be pushed to move towards the cylinder 26 and press against the outside of the cylinder 26 to fix the position of the rotating rod 27 inside the cylinder 26. Finally, the reflector 212 can be rotated by rotating the reflector 212 through the connecting rod 211 to adjust the angle of the reflector 212 on one side of the housing 1. More sliding rods 22 can be installed in the same way, or sliding rods 22 can be installed at the auxiliary blocks 218 at both ends of the housing 1. When the lighting is working, the microwave induction plate emits and receives microwave signals. When a person or object moves within the sensing range, it will cause the microwave signal to be reflected and changed. After the induction plate detects this change, it transmits the signal to the controller, which increases the power of the substrate 5 and emits brighter light. The reflector 212 can reflect the light emitted by the substrate 5 and reflect the light of the lighting lamp that was shone on the ineffective irradiation area to the effective area. After the person moves away, the power of the substrate 5 decreases and the brightness becomes lower. The protective frame 3 and the explosion-proof glass 4 on the outside can protect the substrate 5 inside.
