Description
Technical Field
[0001] This invention relates to the field of explosion-proof LED lighting technology, specifically to an explosion-proof LED light with a dimming structure and a dimming method. Background Technology
[0002] LED explosion-proof lights are a type of explosion-proof light designed to prevent the ignition of surrounding explosive mixtures, such as explosive gas atmospheres, explosive dust atmospheres, and methane atmospheres. One type of LED explosion-proof light allows direct adjustment of the LED light intensity via a dimming unit module, increasing the illuminated area. In demanding environments such as paint shops, mines, and quarries, it is often necessary to install one LED explosion-proof light at intervals to meet nighttime lighting needs.
[0003] However, LED explosion-proof lights generally illuminate the surroundings evenly, but the actual area that needs to be illuminated only occupies a small portion of the LED explosion-proof light's illumination range. The light shining outside the area that needs to be illuminated is essentially wasted. Existing LED explosion-proof lights cannot concentrate the light on the area that needs to be illuminated, and instead rely on increasing the brightness of the entire range to ensure the light intensity of the area that needs to be illuminated, thus resulting in a large waste of electricity.

[0029] Please see Figure 1-7 This invention provides a technical solution: an explosion-proof LED lamp with a dimming structure, comprising a housing 1, with a circuit base 2 and a partition 3 fixedly connected to the upper and lower sides of the housing 1 respectively. A conduit 4 is fixedly connected to the lower end of the circuit base 2, and the lower end of the conduit 4 extends to the lower part of the partition 3 and is fixedly connected to a lamp base 5. LED lamp cores 6 are densely distributed on the outer wall of the lamp base 5. An adjustable reflector mechanism is provided on the outer side of the lamp base 5. The adjustable reflector mechanism includes a central reflector 7 located on one side of the lamp base 5. An angle flip rod 8 is rotatably connected to each of the four corners of the side of the central reflector 7 facing the lamp base 5. Side reflectors 9 are hinged to each of the four sides of the side of the central reflector 7 facing the lamp base 5. The axis of rotation of the angle flip rod 8 and the axis of rotation of the hinge are both located in the same plane. Above, the angle between the axis of rotation of the corner flip rod 8 and the axis of rotation of the adjacent hinge is 45 degrees. The side reflector 9 is movably connected to the two sides of the two corner flip rods 8 on the same side. The arc reflector 10 is hinged to the adjacent corner flip rod 8. The side of the center reflector 7, the side reflector 9 and the arc reflector 10 near the LED lamp core 6 is provided with a reflective coating. An expansion and contraction adjustment mechanism is provided between the corner flip rod 8 and the center reflector 7. The expansion and contraction adjustment mechanism can adjust the four corner flip rods 8 to expand outward or contract inward synchronously. An angle adjustment mechanism is provided between the center reflector 7 and the partition 3. The angle adjustment mechanism can drive the center reflector 7 to rotate 360 degrees around the lamp base 5 in both directions and can drive the center reflector 7 to flip up and down.
[0030] When the above solution is put into practical use, the explosion-proof LED light is installed and powered on. The LED chip 6 illuminates and begins to provide light. The explosion-proof LED light can be adjusted by simultaneously rotating the four corner flip rods 8 towards the lamp base 5 via the telescopic adjustment mechanism. The corner flip rods 8 drive the side reflectors 9 towards the lamp base 5 via the arc-shaped reflector 10. At the same time, the two sides of the side reflectors 9 gradually retract into the arc-shaped slots of the arc-shaped reflector 10, thereby reducing the retraction of the adjustable reflector mechanism and increasing the brightness of the explosion-proof light until the distant area that needs to be illuminated is clearly lit. The explosion-proof LED light can be adjusted by... The four corner flipping rods 8 are simultaneously flipped away from the lamp base 5 by the extension and retraction adjustment mechanism. The corner flipping rods 8 drive the side reflectors 9 to flip away from the lamp base 5 through the arc-shaped reflector 10. At the same time, the two sides of the side reflectors 9 gradually extend out of the arc-shaped slots of the arc-shaped reflector 10, thereby expanding the adjustable reflector mechanism outward and increasing the illumination range of the explosion-proof lamp until the illumination range completely covers the surrounding area that needs to be illuminated. This explosion-proof LED lamp can drive the center reflector 7, corner flipping rods 8, side reflectors 9 and arc-shaped reflectors 10 to surround the lamp base 5 in a 360-degree arc. The explosion-proof LED light can be adjusted by rotating it clockwise and counterclockwise to change its horizontal illumination angle. The angle adjustment mechanism allows the central reflector 7, corner flip rod 8, side reflector 9, and curved reflector 10 to rotate upwards or downwards, thus adjusting the vertical illumination angle. Furthermore, the expansion and contraction mechanism allows the angle flip rod 8, side reflector 9, and curved reflector 10 to be adjusted, with the expansion increasing the lighting range. The retraction of the corner flip rod 8, the side reflector 9, and the arc-shaped reflector 10 can improve the brightness and effective range of the explosion-proof LED light, concentrate the beam to illuminate the area to be illuminated, and reduce the energy consumption required for lighting while ensuring that the area to be illuminated is illuminated. The explosion-proof LED light can rotate the irradiation beam 360 degrees forward and backward and flip it up and down through the angle adjustment mechanism, and can illuminate the areas to be illuminated around the explosion-proof LED light with the cooperation of the expansion and contraction adjustment mechanism, thereby reducing the arrangement density of fixed explosion-proof lights and reducing the number of times mobile explosion-proof lights are moved.
[0031] As a further embodiment of the present invention, the expansion and contraction adjustment mechanism includes an annular bevel gear 11, which is located outside the central reflector 7 and rotatably connected to the central reflector 7. The annular bevel gear 11 meshes with four first bevel gears 12 located at the four corners of the central reflector 7. Each of the first bevel gears 12 is rotatably connected to the central reflector 7. Each of the first bevel gears 12 meshes with a second bevel gear 13, which is rotatably connected to the central reflector 7. The rotation shaft of the second bevel gear 13 is fixedly connected to a first gear 14. The first gear 14 meshes with a rack 15. The rack 15 is slidably connected to a U-shaped sleeve 16, which is rotatably connected to the rotation shaft of the second bevel gear 13. One end of the rack 15 away from the first gear 14 is hinged to a corner flipping rod 8. A first driving mechanism for driving the annular bevel gear 11 to rotate is provided between the annular bevel gear 11 and the central reflector 7.
[0032] When the above scheme is put into actual use, the first drive mechanism drives the ring bevel gear 11 to rotate clockwise or counterclockwise, the ring bevel gear 11 drives the first bevel gear 12 to rotate, the first bevel gear 12 drives the second bevel gear 13 and the first gear 14 to rotate, and the first gear 14 drives the rack 15 to slide along the U-shaped sliding sleeve 16. When the rack 15 slides away from the lamp base 5, the angle flipping rod 8 flips away from the lamp base 5 under the drive of the rack 15, thereby causing the angle flipping rod 8, the side reflector 9 and the arc reflector 10 to expand outward. When the rack 15 slides towards the lamp base 5, the angle flipping rod 8 flips towards the lamp base 5 under the drive of the rack 15, thereby causing the angle flipping rod 8, the side reflector 9 and the arc reflector 10 to retract inward.
[0033] As a further embodiment of the present invention, the angle adjustment mechanism includes a ring gear 17, which is located at the bottom of the partition 3 and rotatably connected to the partition 3. The ring gear 17 is concentrically arranged with the through pipe 4. Two connecting rods 18 are fixedly connected to the lower side of the ring gear 17, which are respectively located on both sides of the central reflector 7. The lower ends of the connecting rods 18 are rotatably connected to the central reflector 7. An electric telescopic rod 19 is hinged to the lower side of the ring gear 17. The end of the electric telescopic rod 19 away from the ring gear 17 is hinged to the central reflector 7. A second driving mechanism for driving the ring gear 17 to rotate is provided between the ring gear 17 and the partition 3.
[0034] When the above scheme is put into actual use, the second drive mechanism drives the ring gear 17 to rotate clockwise or counterclockwise. The ring gear 17 drives the center reflector 7 to rotate through the connecting rod 18, thereby enabling the center reflector 7, the corner flip rod 8, the side reflector 9, and the arc reflector 10 to rotate 360 degrees around the lamp base 5 in both directions. At the same time, the extension and retraction of the electric telescopic rod 19 can drive the center reflector 7 to flip up or down, thereby enabling the overall orientation of the center reflector 7, the corner flip rod 8, the side reflector 9, and the arc reflector 10 to be adjusted in terms of vertical angle.
[0035] As a further embodiment of the present invention, the first driving mechanism includes a first motor 20, which is fixedly connected to the central reflector 7. The output shaft of the first motor 20 is fixedly connected to a third bevel gear 21, which meshes with an annular bevel gear 11. During operation, when the first motor 20 is started, it can drive the third bevel gear 21 to rotate in both directions through its output shaft. The third bevel gear 21 drives the annular bevel gear 11 to rotate, thereby enabling the expansion and contraction adjustment mechanism to adjust the diagonal flipping rod 8, the side reflector 9, and the arc-shaped reflector 10.
[0036] As a further embodiment of the present invention, the second driving mechanism includes a second motor 22, which is fixed to the upper surface of the partition 3. The output shaft of the second motor 22 extends to the lower side of the partition 3 and is fixedly connected to a second gear 23. The second gear 23 meshes with the ring gear 17. During operation, the second motor 22 starts and drives the second gear 23 to rotate in both directions through its output shaft. The second gear 23 drives the ring gear 17 to rotate, thereby realizing the adjustment of the center reflector 7, the corner flip rod 8, the side reflector 9 and the arc reflector 10 to rotate 360 degrees around the lamp base 5.
[0037] As a further embodiment of the present invention, a rectangular groove 24 is provided in the middle of the upper side reflector 9 corresponding to the through pipe 4. A rectangular sleeve 25 is rotatably connected to the outside of the through pipe 4. The front and rear sides of the rectangular sleeve 25 are respectively in contact with the front and rear sides of the rectangular groove 24. A first sliding plate 26 and a second sliding plate 27 are slidably connected to the inside of the rectangular groove 24. The first sliding plate 26 and the second sliding plate 27 are respectively located on the side of the rectangular sleeve 25 away from the central reflector 7 and the side of the rectangular sleeve 25 close to the central reflector 7. A first spring 28 and a second spring 29 are respectively fixedly connected between the side of the upper surface of the first sliding plate 26 and the side reflector 9 on the upper side. A reflective coating is provided on the side of the first sliding plate 26 and the side of the second sliding plate 27 close to the lamp base 5.
[0038] When the above solution is put into actual use, when the upper side reflector 9 is flipped relative to the conduit 4, the angle and relative position between the upper side reflector 9 and the rectangular sleeve 25 change accordingly. The first sliding plate 26 and the second sliding plate 27 can slide along the rectangular groove 24 under the elastic force of the first spring 28 and the second spring 29 respectively and always stick to the outer wall of the rectangular sleeve 25. When the upper side reflector 9 rotates around the conduit 4, the rectangular sleeve 25 rotates together with the upper side reflector 9 under the limiting action of the first sliding plate 26, the second sliding plate 27 and the rectangular groove 24, thereby avoiding gaps between the upper side reflector 9 and the conduit 4 due to flipping or rotating, thus preventing light leakage during illumination and ensuring the intensity of illumination.
[0039] As a further embodiment of the present invention, a light-transmitting sealing cover 30 located outside the lamp base 5 and the adjustable reflector mechanism is fixedly connected to the lower end of the outer shell 1. A protective cover 31 is fitted on the outside of the light-transmitting sealing cover 30, and the protective cover 31 is fixedly connected to the outer shell 1. During operation, the light-transmitting sealing cover 30 serves to protect and transmit light, while the protective cover 31 serves to further enhance protection.
[0040] A dimming method for an explosion-proof LED light with a dimming structure, the method comprising the following steps:
[0041] Step 1: Install and fix the explosion-proof LED light and turn it on for illumination;
[0042] Step 2: The angle adjustment mechanism operates and the orientation of the adjustable reflector is adjusted to face the area that needs to be illuminated;
[0043] Step 3: The expansion and contraction adjustment mechanism operates, causing the corner flip rod 8, the side reflector 9, and the arc reflector 10 to expand or contract synchronously until the lighting brightness reaches the set value and the lighting range can cover the area that needs to be illuminated.
[0044] Working Principle: When the explosion-proof LED light is installed and powered on, the LED chip 6 illuminates. The explosion-proof LED light can be adjusted by simultaneously rotating the four corner flip rods 8 towards the lamp base 5 via the extension and retraction mechanism. The corner flip rods 8, through the arc-shaped reflector 10, drive the side reflectors 9 towards the lamp base 5. Simultaneously, the two sides of the side reflectors 9 gradually retract into the arc-shaped slots of the arc-shaped reflector 10, thereby retracting the adjustable reflector mechanism and increasing the brightness of the explosion-proof light until the distant area requiring illumination is clearly lit. This explosion-proof LED light can be adjusted via the extension and retraction mechanism... The mechanism simultaneously rotates the four corner flip rods 8 away from the lamp base 5. The corner flip rods 8, via the arc-shaped reflector 10, drive the side reflectors 9 to rotate away from the lamp base 5. Simultaneously, the two sides of the side reflectors 9 gradually extend outward from the arc-shaped slots of the arc-shaped reflector 10, thereby expanding the adjustable reflector mechanism outward and increasing the illumination range of the explosion-proof lamp until the illumination range completely covers the surrounding area requiring illumination. This explosion-proof LED lamp can be adjusted by the angle adjustment mechanism to cause the center reflector 7, corner flip rods 8, side reflectors 9, and arc-shaped reflectors 10 to rotate 360 degrees clockwise and counterclockwise around the lamp base 5. The angle adjustment mechanism allows for adjustment of the horizontal illumination angle of the explosion-proof LED light. The mechanism also enables the center reflector 7, corner flip rod 8, side reflector 9, and curved reflector 10 to rotate upwards or downwards, thus adjusting the vertical illumination angle. Furthermore, the expansion and contraction mechanism allows for adjustment of the angle flip rod 8, side reflector 9, and curved reflector 10. The expansion of these components increases the illumination range of the explosion-proof LED light. The retraction of the flip rod 8, the side reflector 9, and the arc-shaped reflector 10 can improve the brightness and effective range of the explosion-proof LED light, concentrate the beam to illuminate the area to be illuminated, and reduce the energy consumption required for lighting while ensuring that the area to be illuminated is illuminated. The explosion-proof LED light can rotate the irradiation beam 360 degrees forward and backward and flip it up and down through the angle adjustment mechanism, and can illuminate the area to be illuminated around the explosion-proof LED light with the cooperation of the expansion and contraction adjustment mechanism, thereby reducing the arrangement density of fixed explosion-proof lights and reducing the number of times mobile explosion-proof lights are moved.
