Description

Technical Field

[0001] The utility model relates to the technical field of indicator lights, in particular to an ultra-wide voltage compact indicator light. Background Art

[0002] In the early days of electronic technology, voltage indicator lights were primarily based on simple circuit principles and typically operated only within a specific, narrow voltage range. When the voltage exceeded their design range, they could exhibit problems such as insufficient brightness, flickering, or even damage, failing to meet the voltage adaptability requirements of some special applications. Ultra-wide voltage indicator lights, on the other hand, feature a wide voltage input range and operate stably within this range, making them suitable for a variety of applications requiring indication and display. Utilizing advanced LED technology, these indicators provide high brightness, making them clearly visible even in dimly lit environments. However, their larger structure limits their applicable scenarios and scope. Ultra-wide voltage compact indicator lights feature a wide voltage input range, a compact structure, and powerful functionality. They operate stably within a wide voltage range while maintaining a small size and high brightness, making them suitable for a variety of applications requiring indication and display. However, existing ultra-wide voltage compact indicator lights still suffer from complex circuit designs that affect the voltage range, long lamp housings that interfere with the user's cabinet panel, a narrow range of plywood thicknesses that limit their compatibility with a limited range of application scenarios, and small wiring windows that make installation and maintenance inconvenient. Utility Model Content

[0003] In order to solve at least one of the problems existing in the above-mentioned background technology, the present invention provides an ultra-wide voltage compact indicator light, which is a compact indicator light with the shortest lamp shell. At the same time, the circuit of the LED lamp board is optimized using screw wiring, so that it has an ultra-wide voltage design feature.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an ultra-wide voltage compact indicator light, comprising a lampshade and a short shell, the top end of the short shell is fixedly connected to a light-distributing cover, an O-ring is sleeved on the outer side of the top end of the short shell, the upper end of the short shell is snap-connected to the lampshade, a threaded ring is threadedly connected to the middle part of the surface of the short shell, a sealing gasket is provided at the upper end of the threaded ring, a lamp board assembly and a wire-pressing screw assembly connected to the lamp board assembly are fixedly installed in the inner cavity of the short shell; the bottom end of the short shell is fixedly connected to a rear end cover.

[0005] The indicator light is connected to the short shell through the snap-fit ​​connection of the lampshade and the cooperation of the threaded ring and sealing gasket, making the assembly and disassembly of the indicator light easier, while ensuring the compactness and sealing of the structure. This design not only facilitates maintenance and replacement, but also improves the reliability and service life of the indicator light. By adopting a short shell design, the overall size of the indicator light is effectively reduced, making it more compact.

[0006] Furthermore, a plurality of evenly distributed support strips are provided in the middle of the inner cavity of the short shell, and a limit plate is provided below the support strip, and both ends of the limit plate are fixedly connected to the inner cavity of the short shell, and through holes are provided at both ends of the surface of the limit plate, and the bottom end of the limit plate is fixedly connected to a partition frame, and the two ends of the partition frame are fixedly connected to the bottom of the inner cavity of the short shell, and wiring windows are provided on both sides of the lower end of the short shell; the uniform distribution of the support strips provides stable support for the LED light board, and prevents deformation or damage of the light board due to vibration or external force. At the same time, the cooperation of the support strips, the limit plates and the partition frame further enhances the structural strength of the interior of the short shell and improves the overall stability of the indicator light. The setting of the partition frame divides the interior of the short shell into different areas, separates the two wire-pressing screw assemblies, prevents the occurrence of electrical interference and short circuit problems, and improves the electrical performance and safety of the indicator light. The wiring windows opened on both sides of the lower end of the short shell not only facilitate the access and disassembly of the wires, but also improves the flexibility and convenience of installation.

[0007] Furthermore, the light panel assembly includes an LED light panel with two through-holes formed on its surface. Both through-holes are movably connected to a wire-pressing screw assembly. A through-hole formed on the surface of the retaining plate provides a mounting location for the wire-pressing screw assembly, allowing wires to neatly pass through the through-holes and securely connect to the LED light panel. This design not only simplifies wire management but also reduces safety hazards caused by cluttered wires.

[0008] Furthermore, the wire-pressing screw assembly includes a short screw and a gasket, and the gasket is threadedly connected to the middle part of the short screw surface, one side of the gasket is fixedly connected with an extension piece, the top of the extension piece passes through the through hole of the lamp board and extends to the top of the through hole of the lamp board, the lower end of the short screw surface is threadedly connected to the wire-pressing piece, the upper end of the short screw surface is threadedly connected to the wire-pressing block, and a short clamping column is provided in the middle part of the upper surface of the wire-pressing block, and the surface of the short clamping column abuts against the inner surface of the through hole; the wire-pressing screw assembly realizes reliable clamping of the wires through the combination of the short screw, gasket, extension piece, wire-pressing piece and wire-pressing block. Fixed, the extension piece passes through the through hole of the lamp panel and extends to the top, cooperating with the wire pressing block to firmly clamp the wire between the wire pressing piece and the extension piece, preventing the wire from loosening or falling off due to vibration or external force. The design of the short clamping column not only increases the firmness of the connection, but also prevents the connection from loosening or disconnecting due to vibration or external force, thereby ensuring the electrical performance stability of the indicator light. The compact design of the wire pressing screw assembly reduces the occupancy of the internal space, allowing heat to be more effectively dissipated through the short shell and the light-distributing cover. The modular design makes it more convenient and quick when it needs to be repaired or replaced.

[0009] Furthermore, the surface of the rear end cover is provided with two end cover bottom holes, and both sides of the two end cover bottom holes are provided with limit strips, and the bottom ends of the two limit strips are fixedly connected to the upper surface of the rear end cover, and both sides of the upper surface of the rear end cover are provided with arc-shaped convex plates, and the height of the arc-shaped convex plates matches the height of the wiring window; the top of the rear end cover is fixedly connected to the bottom end of the short shell, ensuring the stability of the internal structure of the indicator light, and the arc-shaped convex plate matches the height of the wiring window, so that heat can be more effectively dissipated through the rear end cover. The design of the rear end cover makes the installation and maintenance process of the indicator light more convenient, and maintenance personnel can easily access, fix and inspect the wires through the rear end cover without disassembling the entire indicator light or destroying its structure.

[0010] Preferably, the size of the wiring window is 3.3*8mm, and the diameter of the bottom hole of the end cover is 6.2mm; the size design of the wiring window and the bottom hole of the end cover makes it more convenient and quick to repair or replace parts of the indicator light.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] This ultra-wide voltage compact indicator light optimizes the circuit of the LED light board through the use of screw wiring to achieve upgrade and cost reduction. It is a compact indicator light with the shortest lamp shell, which minimizes the interference with the user's cabinet panel while ensuring the thickness of the plywood.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] Please refer to this Figure 1-9 The utility model provides an ultra-wide voltage compact indicator light, including a lampshade 1 and a short shell 7. The top of the short shell 7 is fixedly connected to the light-distributing cover 2, and the outer side of the top of the short shell 7 is sleeved with an O-ring 3. The upper end of the short shell 7 is snap-fitted with the lampshade 1, and the middle part of the surface of the short shell 7 is threadedly connected with a threaded ring 23. The upper end of the threaded ring 23 is provided with a sealing gasket 4. The bottom end of the short shell 7 is fixedly connected to the rear end cover 19, and the top of the inner cavity of the short shell 7 is fixedly installed with a lamp board assembly.

[0025] When in use, the lampshade 1 protects the internal light source, the light emitting cover 2 provides a suitable light source scattering effect, the O-ring 3 prevents dust and moisture from entering the interior of the indicator light, the threaded ring 23 and the sealing gasket 4 ensure a tight connection between the various parts, and the rear end cover 19 closes the bottom of the short shell 7, protects the internal components, and provides a wire lead-out hole or other interface.

[0026] A number of evenly distributed support bars 8 are provided in the middle of the inner cavity of the short shell 7, and a limit plate 9 is provided below the support bar 8. Both ends of the limit plate 9 are fixedly connected to the inner cavity of the short shell 7. Through holes 10 are provided at both ends of the surface of the limit plate 9. The bottom end of the limit plate 9 is fixedly connected to a partition frame 11, and both ends of the partition frame 11 are fixedly connected to the bottom of the inner cavity of the short shell 7. Wiring windows 12 are provided on both sides of the lower end of the short shell 7.

[0027] When in use, the support bar 8 is evenly distributed in the middle of the inner cavity of the short shell 7, ensuring that the LED light board 5 is stably installed in the short shell 7. The partition frame 11 separates different areas in the short shell 7, providing space for two screw wiring components, making the internal layout of the indicator light more reasonable, and reducing interference and mutual influence between components. The limit plate 9 not only provides additional structural support, but also passes wires or other connectors through the through holes 10 on its surface to achieve electrical connection between internal components and external power supplies or other devices, so that the wires can be neatly arranged under the limit plate 9.

[0028] The light board assembly includes an LED light board 5. Two light board through holes 6 are provided on the surface of the LED light board 5. The surfaces of the two light board through holes 6 are movably connected with wire pressing screw assemblies.

[0029] When in use, the wire pressing screw assembly fixes the wires inside the lamp body while providing power to the LED lamp board 5, ensuring stable lighting of the LED lamp board 5 and improving the reliability and service life of the indicator light.

[0030] The wire pressing screw assembly includes a short screw 13 and a gasket 15, and the gasket 15 is threadedly connected to the middle part of the surface of the short screw 13. An extension piece 16 is fixedly connected to one side of the gasket 15. The top of the extension piece 16 passes through the lamp board through hole 6 and extends to the top of the lamp board through hole 6. The lower end of the short screw 13 is threadedly connected to the wire pressing piece 14, and the upper end of the short screw 13 is threadedly connected to the wire pressing block 17. A short clamping column 18 is provided in the middle of the upper surface of the wire pressing block 17, and the surface of the short clamping column 18 abuts against the inner surface of the through hole 10.

[0031] When in use, the surface of the short clamping column 18 is in close contact with the inner surface of the through hole 10 and produces an abutment effect, ensuring that the entire wire pressing screw assembly can be firmly installed in the required position. Rotating the short screw 13 causes the wire pressing piece 14 and the wire pressing block 17 to move downward or upward at the same time, generating appropriate clamping force on the circuit or component. At the same time, the abutment of the short clamping column 18 with the through hole 10 further increases the stability of the entire assembly, preventing it from loosening or falling off during operation.

[0032] Two end cover bottom holes 20 are opened on the surface of the rear end cover 19, and limiting clips 21 are provided on both sides of the two end cover bottom holes 20. The bottom ends of the two limiting clips 21 are fixedly connected to the upper surface of the rear end cover 19. Arc-shaped convex plates 22 are provided on both sides of the upper surface of the rear end cover 19, and the height of the arc-shaped convex plates 22 matches the height of the wiring window 12.

[0033] When in use, the top of the rear end cover 19 and the bottom end of the short shell 7 are fixedly connected to protect the electronic components and circuits inside the indicator light. The two end cover bottom holes 20 opened on the surface of the rear end cover 19 provide a channel for the lead-out of the wires. The limiting strips 21 on both sides of the end cover bottom holes 20 are fixedly connected to the upper surface of the rear end cover 19 to form a stable support structure. When the wires are led out from the end cover bottom holes 20, the limiting strips 21 can effectively prevent the wires from shaking or falling off when subjected to external force, thereby ensuring the firmness and reliability of the wire connection.

[0034] The size of the wiring window 12 is 3.3*8 mm, and the diameter of the bottom hole 20 of the end cover is 6.2 mm.

[0035] When in use, users can easily disassemble and replace damaged parts during installation or maintenance, such as Figure 9 As shown, the circuit module of the indicator light includes a feedback control unit, a protection unit, a current detection unit, a drive signal management unit, a power management unit and a start-up unit. The simple circuit design meets the requirements of 3C design, has anti-induction function, and the induction voltage is adjustable. The two voltage levels cover DC6V--DC140V and AC70V--AC400V, and have the applicability of ultra-wide voltage.

[0036] When the embodiment of the present application is in use: first, the lampshade 1 acts as an external protective layer to protect the internal light source LED lamp board 5, and the light-distributing cover 2 allows the light emitted by the LED lamp board 5 to be evenly scattered. The addition of the O-ring 3 at the snap-fit ​​connection between the short shell 7 and the lampshade 1 ensures a tight seal between the two to prevent the intrusion of dust and moisture. The threaded ring 23 and the sealing gasket 4 at its upper end further enhance the connection tightness between the various parts of the indicator light. The uniform distribution of the support bar 8 provides stable support for the LED lamp board 5 and ensures its correct position in the short shell 7. The through hole 10 on the surface of the limit plate 9 passes through the wires or other connectors to realize the electrical connection between the internal components and the external power supply or other equipment. The addition of the partition frame 11 separates different areas in the short shell 7 and provides sufficient space for two screw wiring assemblies. Rotating the short screw 13 causes the wire pressing piece 14 and the wire pressing block 17 to move downward or upward at the same time, generating appropriate pressing force on the circuit or component. The wiring window 12 and the bottom hole 20 of the end cover provide users with convenient wire access and lead-out channels.
