Description

Technical Field

[0001] The present invention relates to the technical field of non-portable lighting devices, and in particular to a voltage-regulated night vision dual-color LED indicator light. Background Art

[0002] At night or in low-light environments, the visibility and applicability of device indicator lights become key requirements. For example, in scenarios such as security monitoring equipment, vehicle-mounted control systems, and industrial instruments, indicator lights are required to clearly convey working status information (such as operation, standby, fault, etc.) in the dark, while also preventing strong light from irritating the human eye or interfering with nighttime visual perception. At the same time, in order to improve the efficiency of information transmission, dual-color display functions have gradually become a mainstream demand. By switching or combining two different colors (such as red and green), the various working modes of the device can be intuitively distinguished, reducing the user's misjudgment of single-color indicator lights. The core principle of voltage-regulated LED signal lights is to dynamically monitor input voltage fluctuations and adjust the output current in real time in combination with a circuit feedback mechanism to ensure that the LED emits stable light within a wide voltage range while avoiding damage to components caused by overvoltage and undervoltage. For signal lights used outdoors or in harsh environments, dustproofing and other protective properties are crucial to prevent short circuits or component damage caused by dust ingress. Existing LED indicator lights are mostly dustproofed with sealants or one-piece molded housings, making it difficult to repair and replace parts, resulting in high repair and replacement costs. Furthermore, to ensure the clarity of the signal lights, operators must sweep and blow away dust from the light surface and installation gaps. In view of the above technical defects, a solution is now proposed. Summary of the Invention

[0008] Furthermore, a track is fixed to one end of the mounting plate close to the connecting shell, and the embedded plate, the mounting plate and the track are all elliptical in shape, and the inner diameter of the track is between the outer diameter of the mounting plate and the outer diameter of the embedded plate.

[0009] Furthermore, two compound rotating pairs are distributed on the upper and lower ends of the mounting frame, and the four fixed ends of the compound rotating pairs are fixedly connected to the mounting frame.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] like Figure 1-Figure 3 As shown, the voltage-regulated night-vision two-color LED indicator light of this embodiment includes a two-color lamp element 1 fixedly mounted in a lampshade 3. The outer wall of the lampshade 3 is interference-fitted with a connecting shell 202 via a sealing ring 8. A protective shell 201 is integrally formed on the end of the connecting shell 202 away from the lampshade 3. The connecting shell 202 is provided with a cleaning mechanism for reinforcing the installation of the lampshade 3 and removing dust, as well as a convenient disassembly mechanism for detachably mounting the LED indicator light on the working machine and cleaning the connection gap. The bi-color lamp element 1 includes a bi-color LED chip, electrodes, a current-limiting resistor, pins, a voltage detection module based on a voltage sensor, a voltage regulation execution unit based on a switching power supply, a feedback circuit for output voltage information feedback, a microcontroller, and a drive circuit. The above structures are all fixed in the lampshade 3 by a bracket of matching specifications. The bracket and lampshade 3 are fixed by screws. The above specific structure and working principle are all existing technologies and will not be repeated here. The lampshade 3 is made of transparent acrylic. During installation, the sealing ring 8 is fixed tightly against the inner wall of the connecting shell 202. The outer wall of the lampshade 3 is chamfered near one end of the connecting shell 202. The chamfer is aligned with the inner ring of the sealing ring 8 and pressed in. The sealing ring 8 is interference fit between the lampshade 3 and the connecting shell 202 to achieve fixed installation.

[0017] like Figure 3-Figure 4 As shown, the dust cleaning mechanism includes a fixed plate 4 fixed to the top of the protective shell 201, and the fixing plate 4 is fixed with an electric push rod 5 mounting end by screws at one end close to the lampshade 3, and the movable end of the electric push rod 5 is fixed with one end of a fixed tee 6 by screws, and the inner walls of the other two ends of the fixed tee 6 penetrate and are fixed with a mounting frame 7, and the sealing ring 8 is in contact with a push plate 9 at one end away from the protective shell 201, and two connecting rods 10 are fixed to the end of the push plate 9 away from the sealing ring 8. The two connecting rods 10 are fixedly connected to both sides of the mounting frame 7, and a dust net 11 is fixed to the inner wall of the connecting shell 202 away from the protective shell 201. 1 is in contact with the lampshade 3, and two circular holes for the two connecting rods 10 are provided on the dustproof net 11. The connecting rods 10 contact and slide in the circular holes. A water-absorbing cotton 16 is provided between the dustproof net 11 and the push plate 9. The connecting rods 10 are fixed with a fixed end of a rebound shaft 12 at one end away from the push plate 9, and a square hoop 13 is fixed to the mounting end of the rebound shaft 12. The square hoop 13 is rotatably connected to the end away from the rebound shaft 12 with a rotating drum 14. A dust-removing cloth 15 is fixed to the outer wall of the rotating drum 14. The square hoop 13 and the dust-removing cloth 15 are both in contact with the outer surface of the lampshade 3. The total length of the two square hoops 13 is the same as the distance between the two connecting rods 10.

[0018] The dust-proof net 11 is a stainless steel net. There is no gap between the connecting rod 10 and the circular hole on the dust-proof net 11, and the absorbent cotton 16 is made of polyester fiber. There are many pores and channels of uniform size distributed therein. When squeezed from one end in the channel, the air in the channel is output to the other end. The rebound shaft 12 is an I-shaped shaft with a spring sleeved on it. The I-shaped shaft is provided with discs on the upper and lower parts of the shaft. The upper disc is welded and fixed to the shaft, and the lower disc is rotatably connected to the shaft. One end of the spring is fixed to the upper disc to form a fixed end of the rebound shaft 12, and the other end of the spring is fixed to the lower disc to form a mounting of the rebound shaft 12. The spring restoring force in the rebound shaft 12 drives the square hoop 13 to rotate toward the center of the lampshade 3. The dust-removing cloth 15 is an electrostatic cloth, which is made of Velcro with double-sided tape at both ends and is put on the rotating drum 14 through the adhesive of the Velcro. The Velcro can be disassembled and replaced. The rotating drum 14 and the square hoop 13 are rotatably connected by a bearing. The inner ring of the bearing is interference fit with the square hoop 13, and the outer ring of the bearing is interference fit with the rotating drum 14. The bearing is a ball bearing, which is composed of an inner ring, an outer ring and a ball. The electric push rod 5 is a micro electric push rod, and the model is preferably BST-YF-MN2; When installing the lampshade 3, the operator holds the rotating drum 14 with both hands, applies force in opposite directions to pull the square hoop 13 in the opposite direction of the restoring force of the rebound shaft 12. At this time, the lampshade 3 is pressed to the inner ring of the sealing ring 8 to achieve fixation. When the lampshade 3 is pressed to the bottom, the square hoop 13 is released, and the restoring force of the rebound shaft 12 drives the square hoop 13 to rotate in the direction of the lampshade 3, and always squeezes the lampshade 3 in the direction of the connecting shell 202 to achieve reinforcement; when cleaning the lampshade 3 and the mesh surface of the dust-proof net 11, put the dust-removing cloth 15 on the rotating drum 14, and adhere the Velcro on the dust-removing cloth 15 to install the dust-removing cloth 15, run the electric push rod 5, the electric push rod 5 extends, the mounting frame 7 moves with the electric push rod 5 through the fixed tee 6, the connecting rod 10 moves with the mounting frame 7, and the push plate 9 moves with the connecting rod 10 moves, and the push plate 9 squeezes the absorbent cotton 16 during the movement. The absorbent cotton 16 is squeezed between the dust-proof net 11 and the push plate 9, and the air and a small amount of moisture in the pore channel of the absorbent cotton 16 are squeezed toward the dust-proof net 11, thereby achieving dust blowing and dust removal on the surface of the dust-proof net 11; while the connecting rod 10 moves, the rebound shaft 12 moves with the connecting rod 10, and the restoring force of the rebound shaft 12 drives the angle between the plane where the square hoop 13 is located and the plane where the front end of the lampshade 3 is located to gradually reduce, and the rotating drum 14 moves with the square hoop 13 on the plane where the front end of the lampshade 3 is located, and the dust-removing cloth 15 rotates with the rotating drum 14 on the front end plane of the lampshade 3, adsorbing dust on its surface, thereby achieving surface cleaning of the front end of the lampshade 3 and improving the luminous efficiency of the LED indicator.

[0019] like Figure 5 As shown, the easy-to-disassemble mechanism includes an embedded plate 31 fixed to the outer wall of the connecting shell 202 near one end of the protective shell 201. The embedded plate 31 is made of stainless steel and coated with a silicone rubber layer. The outer wall of the embedded plate 31 is interference-fitted with the mounting plate 17. The outer wall of the mounting plate 17 has ear plates evenly distributed and fixedly connected. The mounting plate 17 is fixed to one end of the connecting shell 202 with a track 18. The embedded plate 31, the mounting plate 17, and the track 18 are all elliptical in shape, and the inner diameter of the track 18 is between the outer diameter of the mounting plate 17 and the outer diameter of the embedded plate 31. The surface of the end of the embedded plate 31 close to the mounting plate 17 is chamfered to facilitate the positioning and installation of the embedded plate 31 and the mounting plate 17. The track 18 is composed of two elliptical ring bodies, the middle part of the rear end of which is connected and fixed to the mounting plate 17 by a fixing block. The thickness of the fixing block is the distance between the track 18 and the mounting plate 17. After the operator presses the mounting plate 17 to the appropriate position on the surface of the device where the LED indicator light needs to be installed, the operator passes the screws through the ear plate and tightens them to achieve the fixed installation of the mounting plate 17. Then, the operator aligns the embedded plate 31 with the inner wall of the mounting plate 17 and presses the embedded plate 31 into the embedded plate 31. The silicone rubber layer on the surface of the embedded plate 31 generates a strong friction force through extrusion deformation, and the friction force acts between the embedded plate 31 and the mounting plate 17 to achieve the preliminary fixed installation of the embedded plate 31 and the mounting plate 17.

[0020] like Figure 6-Figure 7As shown, two compound rotating pairs 19 are distributed at the upper and lower ends of the mounting frame 7. The fixed ends of the four compound rotating pairs 19 are fixedly connected to the mounting frame 7. A long rod 20 is fixed to the movable end of the compound rotating pair 19. An inner ball 21 is fixed to the end of the long rod 20 away from the compound rotating pair 19. An outer ball 22 is movably connected to the outer surface of the inner ball 21. A ball groove with an inner diameter the same as the outer diameter of the inner ball 21 is provided at the bottom of the outer ball 22. The inner ball 21 is embedded and movable in the ball groove. A movable spacing is provided between the edge of the ball groove and the long rod 20. A first curved rod 23 is fixed to the top of the outer ball 22. The first curved rod 23 is away from the outer ball 22. One end is detachably connected to a limiting column 28 through a detachable component. The limiting column 28 is clamped and slides in the track 18. A second bent rod 29 is fixed to the end of the limiting column 28 away from the track 18. A cleaning brush 30 is fixed to the end of the second bent rod 29 away from the limiting column 28. The second bent rod 29 and the cleaning brush 30 are both located between the track 18 and the embedded plate 31. The cleaning brushes 30 are in contact with the embedded plate 31 and the mounting plate 17. The cleaning brush 30 is arc-shaped, and the cleaning brushes 30 distributed up and down are fixedly connected to the second bent rod 29 near the opposite side at one end away from the embedded plate 31.

[0021] The compound revolving pair 19, i.e., two revolving pairs with perpendicular rotation directions, are installed in sequence to achieve flexible rotation between the long rod 20 and the mounting frame 7 in the front, back, left, and right directions. Solid lubricant is squeezed between the inner ball 21 and the outer ball 22, so that the inner ball 21 can flexibly rotate in the ball groove of the outer ball 22. The limit column 28 is a structure with a limit plate fixed at the end of the column. The limit plate is clamped at both ends of the track 18, and the column slides on the inner wall of the track 18. The cleaning brush 30 is a structure with nylon bristles installed on a curved brush plate; When the electric push rod 5 is extended, the long rod 20 rotates with the electric push rod 5. As the electric push rod 5 is extended, the length of the long rod 20 is not enough to adapt to the distance between the compound rotating pair 19 and the connection point between the cleaning brush 30 and the limit column 28. The limit column 28 slides spontaneously toward the short side of the ellipse where the track 18 is located. During the sliding process, the compound rotating pair 19 rotates to adapt to the rotation direction, and the inner ball 21 rolls in the ball groove of the outer ball 22 to adapt to the rotation. When the electric push rod 5 is extended to its longest length, the limit column 28 is closest to the short side of the ellipse, and the arcs of the corresponding cleaning brushes 30 above and below are opposite. Approaching the end, the ends of the cleaning brush 30 all contact the fixed blocks of the track 18, so that during the extension and retraction of the electric push rod 5, the bristles of the cleaning brush 30 all move on the gap between the mounting plate 17 and the embedded plate 31, thereby removing dust from the gap. In addition, the elliptical shape not only utilizes the different distances between the edge of the ellipse and the center of the circle to enable the long rod 20 to drive the limit column 28 to move along the track of the track 18, but also makes the installation directions between the embedded plate 31 and the mounting plate 17 only two, and the two wicks of the two-color LED lamp can be kept horizontal, which is convenient for positioning and improves the viewing efficiency of the indicator light.

[0022] like Figure 8As shown, the detachable component includes a connecting column 24 fixed to the end of the first curved rod 23 away from the outer ball 22, and the opposite ends of the side walls of the connecting column 24 are provided with mounting grooves, and a spring 25 and a resistance block 26 are provided in the mounting groove. One end of the spring 25 is fixedly connected to the connecting column 24, and the other end of the spring 25 is fixedly connected to the resistance block 26. The outer surface of the connecting column 24 abuts against a connecting tube 27, and the inner wall of the connecting tube 27 is provided with a chamfer near the end of the first curved rod 23. The side wall of the connecting tube 27 is provided with two resistance openings, and the two resistance blocks 26 are both provided in the two resistance openings, and the outer wall of the resistance block 26 is slidably connected and abutted with the resistance opening. The top of the resistance block 26 is provided with a chamfer, and the end of the connecting tube 27 away from the first curved rod 23 is fixedly connected to the limit column 28; The connecting column 24 is indirectly fixedly mounted on the connecting shell 202, and the connecting cylinder 27 is indirectly fixedly mounted on the mounting plate 17; After the embedded plate 31 is pressed into the mounting plate 17, the position of the interference block 26 of the connecting column 24 and the interference port on the connecting tube 27 are aligned, and the connecting column 24 is pressed into the inner wall of the connecting tube 27. The chamfered corner of the interference block 26 contacts the connecting tube 27 to squeeze the spring 25. After the spring 25 is squeezed, the interference block 26 slides into the mounting groove of the connecting column 24. As the connecting column 24 is completely pressed into the connecting tube 27, the interference block 26 and the interference port are on the same vertical line, the interference block 26 slides out of the mounting groove, and the interference block 26 is embedded in the interference port, limiting the movement of the connecting column 24, thereby realizing the detachable fixed installation of the connecting column 24 and the connecting tube 27. When disassembling, press the interference blocks 26 on the same connecting column 24 in opposite directions to pull the connecting column 24 out of the connecting tube 27.

[0023] Working Principle: After the operator presses the mounting plate 17 to the appropriate position on the surface of the device where the LED indicator light is to be installed, the operator passes the screws through the ear plate and tightens them to achieve the fixed installation of the mounting plate 17. Then, the operator aligns the embedded plate 31 with the inner wall of the mounting plate 17 and presses the embedded plate 31 into the embedded plate 31. The silicone rubber layer on the surface of the embedded plate 31 generates a strong friction force through extrusion deformation, and this friction force acts between the embedded plate 31 and the mounting plate 17, achieving the initial fixed installation of the embedded plate 31 and the mounting plate 17. The operator holds the rotating drum 14 with both hands and applies force in opposite directions to pull the square hoop 13 in the opposite direction of the restoring force of the rebound shaft 12, aligns the chamfer of the lampshade 3 with the inner ring of the sealing ring 8 and presses it in. The sealing ring 8 is interference-fitted between the lampshade 3 and the connecting shell 202 to achieve fixed installation. When the lampshade 3 is pressed to the bottom, the square hoop 13 is released. The restoring force of the rebound shaft 12 drives the square hoop 13 to rotate toward the lampshade 3, and the lampshade 3 is always pressed toward the connecting shell 202 to achieve reinforcement. After the embedded plate 31 is pressed into the mounting plate 17, the position of the interference block 26 of the connecting column 24 and the interference port on the connecting tube 27 are aligned, and the connecting column 24 is pressed into the inner wall of the connecting tube 27. The chamfered corner of the interference block 26 contacts the connecting tube 27 to squeeze the spring 25. After the spring 25 is squeezed, the interference block 26 slides into the mounting groove of the connecting column 24. As the connecting column 24 is completely pressed into the connecting tube 27, the interference block 26 and the interference port are on the same vertical line. The interference block 26 slides out of the mounting groove and is embedded in the interference port, limiting the movement of the connecting column 24, thereby realizing the detachable fixed installation of the connecting column 24 and the connecting tube 27. When disassembling, the interference block 26 on the same connecting column 24 is pressed in opposite directions, and the connecting column 24 can be pulled out from the connecting tube 27. When cleaning the lampshade 3 and the surface of the dust-proof net 11, put the dust-removing cloth 15 on the rotating drum 14, and adhere the Velcro on the dust-removing cloth 15 to install the dust-removing cloth 15, run the electric push rod 5, the electric push rod 5 extends, the mounting frame 7 moves with the electric push rod 5 through the fixed tee 6, the connecting rod 10 moves with the mounting frame 7, and the push plate 9 moves with the connecting rod 10. During the movement of the push plate 9, the absorbent cotton 16 is squeezed, and the absorbent cotton 16 is squeezed between the dust-proof net 11 and the push plate 9, and the pore channel of the absorbent cotton 16 is opened. The air and a small amount of moisture in the dustproof net 11 are squeezed toward the dustproof net 11, so as to achieve dust blowing and dust removal on the surface of the dustproof net 11; when the connecting rod 10 moves, the rebound shaft 12 moves with the connecting rod 10, and the restoring force of the rebound shaft 12 drives the angle between the plane where the square hoop 13 is located and the plane where the front end of the lampshade 3 is located to gradually reduce, and the rotating drum 14 moves with the square hoop 13 on the plane where the front end of the lampshade 3 is located, and the dust-removing cloth 15 rotates with the rotating drum 14 on the plane where the front end of the lampshade 3 is located to absorb dust on its surface; When the electric push rod 5 is extended, the long rod 20 rotates with the electric push rod 5. As the electric push rod 5 is extended, the length of the long rod 20 is not enough to adapt to the distance between the compound rotating pair 19 and the connection point of the cleaning brush 30 and the limit column 28. The limit column 28 spontaneously slides toward the short side of the ellipse where the track 18 is located. During the sliding process, the compound rotating pair 19 rotates to adapt to the rotation direction, and the inner ball 21 rolls in the ball groove of the outer ball 22 to adapt to the rotation.
