Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0044] Please see the attached Figure 1 -Attached Figure 4 The first aspect of this embodiment relates to a signal light, comprising a housing 1, a light-emitting assembly 2, a terminal block 3, and a base 4. The light-emitting assembly 2 is disposed within the housing 1 and includes a light-emitting element 21 for generating three colors of light. The terminal block 3 is disposed on the housing 1 and electrically connected to the light-emitting assembly 2. The base 4 covers the terminal block 3 and is detachably connected to the housing 1. A latching protrusion 41 is provided on one of the housing 1 and a latching hole 11 is provided on the other. The latching protrusion 41 can be latched into the latching hole 11.

[0045] In this embodiment, the shell 1 is a circumferentially rotating body, and an installation chamber is provided inside the shell 1, and the light-emitting component 2 is configured in the installation chamber. Among them, the light-emitting component 21 adopts an LED light source. By providing a signal for changing the current and voltage of the LED light source by the user, the brightness and color of the LED light source can be adjusted, so that the LED light source has greater flexibility in lighting indication applications, creating different atmospheres or realizing precise light signal prompts as needed; in addition, the LED light source is a low-voltage driving component, and its operating voltage is generally only a few volts to tens of volts, which is much lower than the operating voltage of traditional lamps. The heat generation of the LED light source is low, which makes the LED light source safer and more reliable during use, less prone to safety accidents such as electric shock, and also has extremely high safety. Therefore, this signal light can realize a multi-color indication function and improve practicality. For example, the light-emitting component 21 can adopt a three-color LED light source.

[0046] The terminal block 3 is electrically connected to the light-emitting element 21 via a guide wire, and is also used to electrically connect to an external circuit (such as a device wire, etc.). At one end of the housing 1, there are two first partitions 16 arranged opposite each other, with a rectangular latching hole 11 provided on the first partition 16. The base 4 is also a circumferentially rotating body, and two opposing latching protrusions 41 are provided near the center of the base 4. When the base 4 and the housing 1 are assembled, the two latching protrusions 41 are respectively latched in the latching holes 11, thereby achieving a latching connection between the base 4 and the housing 1 and preventing the base 4 from falling off the housing 1. In addition, covering the base 4 on the terminal block 3 can prevent the terminal block 3 from being exposed, thereby improving safety.

[0047] It should be noted that the latching holes 11 and latching protrusions 41 of the housing 1 and base 4 can be interchanged. Specifically, the latching protrusion 41 is formed on the housing 1, and the latching holes 11 corresponding to the latching protrusion 41 are formed on the base 4. Those skilled in the art can rationally design and adjust the positions and number of the latching holes 11 and latching protrusions 41 based on the difficulty and cost-effectiveness of the molding process. In other embodiments, the latching holes 11 can be replaced with non-through latching slots, which can still achieve a snap-fit ​​connection with the latching protrusion 41.

[0048] Please see the attached Figure 3 Optionally, the light emitting assembly 2 further includes a plurality of rectifier modules 23 , and the plurality of rectifier modules 23 are electrically connected to different input terminals of the light emitting element 21 respectively.

[0049] Specifically, the light-emitting component 2 includes a circuit board 22 and a plurality of rectifier modules 23. The rectifier modules 23 and the light-emitting element 21 are arranged on the circuit board 22. In this embodiment, the light-emitting element 21 and the rectifier module 23 can be integrated on the circuit board 22 by a chip mounting process or a wafer bonding process. The circuit board 22 is a circular plate to facilitate placement into the installation chamber. The light-emitting element 21 is arranged near the center of the circuit board 22, and three independent rectifier modules 23 are distributed around the circumference of the light-emitting element 21. Furthermore, the light-emitting element 21 can generate three colors of light. The light-emitting element 21 has a common output interface and three independent input interfaces, wherein the three rectifier modules 23 are electrically connected to the light-emitting element 21. The rectifier modules 23 are used to control the light-emitting element 21 to display the corresponding color. When a user's device signal is input, the rectifier module 23 can control the light-emitting element 21 to switch to three different colors of light according to the preset lighting rules.

[0050] Optionally, the light emitting assembly 2 further includes a plurality of step-down elements 24 , one end of each of which is conductively connected to different control interfaces of the light emitting element 21 , and the other end of each of the step-down elements 24 is conductively connected to the terminal 3 .

[0051] Specifically, the entire circuit board 22 is provided with four output welding holes, which are respectively used to weld four voltage-reducing elements 24 . Meanwhile, the other ends of the voltage-reducing elements 24 are electrically connected to the connection terminals 3 .

[0052] The voltage-dropping element 24 ensures that the light-emitting element 21 has a stable and appropriate voltage and current, thereby ensuring normal lighting and color switching. The voltage-dropping element 24 can reduce the input high voltage to the operating voltage of the light-emitting element 21, ensuring stable operation of the light-emitting element 21 and protecting the light-emitting element 21 from overvoltage.

[0053] Please see the attached Figure 6 and attached Figure 8 Optionally, the housing 1 is provided with four fixing portions 12, and the four wiring terminals 3 are respectively provided on the four fixing portions 12. The light-emitting assembly 2 is provided with three pin terminals and a common terminal. The three pin terminals correspond to the three colors of light generated by the light-emitting element 21, and the three pin terminals are respectively electrically connected to the three wiring terminals 3. The common terminal is electrically connected to the wiring terminals 3 that are not connected to the pin terminals. The four fixing portions 12 are arranged around the latch protrusion 41 or the latch hole 11.

[0054] In this embodiment, two opposing second partitions 17 are provided at one end of the housing 1. The first partition 16 and the second partition 17 are in a vertical position, thereby dividing one end of the housing 1 into a "well"-shaped structure, wherein the latch hole 11 is located on the wall surface of the middle grid area of ​​the "well"-shaped structure. The outer grid area surrounding the middle grid area can be used to form a fixing portion 12 to fix the terminal 3, and each terminal 3 is located in an independent outer grid area. The outer grid area makes the multiple terminals 3 independent of each other, avoiding the problem of mutual interference after the multiple terminals 3 are electrically connected, thereby improving safety and stability. Specifically, of the four pin ends on the circuit board 22, three pin ends are electrically connected to three terminals 3 respectively, and the other terminal 3 is electrically connected to the common end. The three pins are used to form a circuit for a three-color signal light to control three colors of light. The four-pin scheme of the circuit board 22 conforms to the circuit layout of the three-color signal light.

[0055] Please continue to refer to the attached Figure 4 Optionally, a lead hole 43 is opened on the side wall of the base 4, and the lead hole 43 is corresponding to the terminal 3.

[0056] The lead hole 43 allows the wires connected to the terminal 3 to be directly inserted into and out of the terminal, thereby facilitating wiring and improving aesthetics.

[0057] Please see the attached Figure 6 and attached Figure 7 Optionally, a lead-out hole 15 is further provided at one end of the housing 1 , and the pin of the voltage-reducing element 24 can pass through the lead-out hole 15 and be welded to the terminal 3 .

[0058] Specifically, the terminal block 3 comprises an L-shaped terminal block 31. A combination screw is screwed onto one of the straight plates of the terminal block 31, while the other straight plate forms a welding surface for welding to the pins of the voltage-reducing element 24. The pins of the voltage-reducing element 24 extend through the lead-out holes 15 and are welded to the terminal block 31. In this embodiment, four terminal blocks 3 are provided for each of the four voltage-reducing elements 24. These four terminal blocks 3 are located in the four outer grid sections of the "well" structure, located at the top, bottom, left, and right sides. The welding locations of the terminal block 31 and the pins of the voltage-reducing element 24 are located in the four outer grid sections of the diagonal lines of the "well" structure. The first and second partitions 16 and 17 provide isolation, ensuring the stability and safety of the electrical connection.

[0059] Please see the attached Figure 2 , Attachment Figure 5 and attached Figure 6 Optionally, a notch 18 is provided on the housing 1 corresponding to each fixing portion 12 .

[0060] Specifically, the notch 18 is formed on the first partition 16 and / or the second partition 17, and the cross-sectional shape of the notch 18 can be trapezoidal or rectangular, wherein the pins of the four voltage-reducing elements 24 are respectively passed through the lead-out holes 15 and welded to the terminal board 31, and the ends of each pin can be extended and bent and placed in the corresponding notch 18, thereby improving the consistency and neatness of the assembly.

[0061] Please see the attached Figure 4 and attached Figure 5 Furthermore, one of the shell 1 and the base 4 is provided with a limiting platform 42, and the other is provided with a limiting groove 13, and the limiting platform 42 is arranged in the limiting groove 13.

[0062] The end surface where the base 4 contacts the housing 1 is provided with a stopper 42. The stopper 42 is in the shape of a rectangular parallelepiped. Correspondingly, a stopper groove 13 is provided on the end surface where the housing 1 contacts the base 4. The stopper groove 13 is a rectangular groove formed on the end surface of the housing 1. When the housing 1 and the base 4 are assembled, the stopper 42 can be inserted into the stopper groove 13, so that the housing 1 and the base 4 can be quickly aligned in the circumferential direction, ensuring smooth and quick connection between the housing 1 and the base 4 during assembly. In addition, the stopper groove 13 or the stopper 42 on the housing 1 can also serve as an indicator of the public interface on the customer's device.

[0063] Of course, in other embodiments, the limiting grooves 13 of the housing 1 and the limiting platforms 42 of the base 4 can also be interchanged, that is, the limiting platforms 42 are formed on the housing 1, and the limiting grooves 13 corresponding to the limiting platforms 42 are formed on the base 4. Those skilled in the art can reasonably design and adjust the positions and numbers of the limiting grooves 13 and limiting platforms 42 based on the difficulty of forming and economic efficiency.

[0064] Please see the attached Figure 5 and attached Figure 9 Optionally, a limiting portion 14 is provided at one end of the shell 1 away from the base 4 and along the circumferential direction. The signal light also includes an inner cover 5, which is covered by the light-emitting component 2 and abuts against the limiting portion 14. The inner cover 5 is made of a light-transmitting material.

[0065] In this embodiment, the limiting portion 14 is an annular end face structure, the inner cover body 5 is pressed against the limiting portion 14 in the axial direction, and the inner cover body 5 is covered on the light-emitting component 2. On the one hand, the entire light-emitting component 2 is enclosed inside the installation chamber to ensure the isolation of internal components, thereby improving the protection performance of internal components. On the other hand, in order to ensure that the light generated by the light-emitting part 21 can be recognized by the user's naked eye, the inner cover body 5 can specifically be made of transparent plastic material or transparent glass material.

[0066] Please see the attached Figure 7 Optionally, an identification structure 141 is provided on the limiting portion 14, and the identification structure 141 is a groove.

[0067] In this embodiment, the end face structure of the limiting portion 14 is recessed inward to form an identification structure 141. The identification structure 141 can be used to indicate the position of the common interface of the circuit board 22. That is, during assembly, the common interface of the circuit board 22 is aligned with the identification structure 141 and installed into the interior of the installation chamber, thereby ensuring the consistency of assembly and the accuracy of the installation direction.

[0068] Please see the attached Figure 10 Optionally, the signal light further includes an outer cover 6 , which is covered on the inner cover 5 and is detachably connected to the housing 1 .

[0069] In this embodiment, the outer wall of the outer cover 6 is directly exposed to the external environment and in direct contact with the external environment. Therefore, the outer cover 6 can be made of wear-resistant and corrosion-resistant materials. The outer cover 6 is also made of a light-transmitting material to ensure that the light generated by the light-emitting element 21 can be recognized by the user. Furthermore, the outer cover 6 is arranged around the outer wall of the housing 1, and can completely surround the inner cover 5. By snapping or screwing the outer cover 6 to the housing 1 and directly pressing the outer cover 6 against the inner cover 5, the inner cover 5 can be further fixed.

[0070] Furthermore, the signal light further includes a sealing gasket 7 and a locking member 8 . The sealing gasket 7 is sleeved on the housing 1 . The locking member 8 is screwed to the outer wall of the housing 1 . The locking member 8 and the outer cover 6 are used to clamp the sealing gasket 7 .

[0071] Specifically, the sealing gasket 7 is an annular plastic part with elasticity. The outer wall of the shell 1 is formed with an external thread. The locking member 8 can adopt a locking nut, which is threadedly engaged with the external thread of the shell 1. When the locking member 8 is screwed, the sealing gasket 7 can be clamped through the combined action of the locking member 8 and the outer cover 6 to prevent dust or moisture from entering the interior of the shell 1 through the locking member 8 and the outer cover 6, thereby improving the waterproof and dustproof performance of the internal components of the signal light and improving the service life of the entire signal light.

[0072] A second aspect of this embodiment also relates to an electrical device, which includes a panel and a signal light thereon, wherein the signal light is detachably connected to the panel.

[0073] Specifically, the signal light can be directly fixed to the panel through screwing, riveting, or clipping, with the light-emitting surface of the signal light exposed on the panel. When the user's device sends a color switching signal, the signal light can promptly change to the set color according to the switching signal, making it easier to obtain device status information in a timely manner. Electrical equipment based on this signal light can realize the multi-color status indication function and switching requirements of the same signal light, improving practicality.

[0074] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
