Detailed Implementation

[0018] This utility model provides an indicator light and its power switch. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] In the description of this utility model, it should be understood that the terms "middle," "inner side," "outer side," etc., indicate the orientation or positional relationship of this utility model based on the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0020] Please see Figures 1 to 7This utility model provides an indicator light, including a bottom shell 1, a mounting cavity with an upward opening inside the bottom shell 1, a driving assembly 2 inside the mounting cavity, an upper shell 3 located at the slot of the mounting cavity on the bottom shell 1, at least one light guide cover 31 inside the upper shell 3, a light-emitting unit 4 located at the lower opening of the light guide cover 31 on the driving assembly 2, and the light-emitting unit 4 being electrically connected to the driving assembly 2; the light-emitting unit 4 is powered by the driving assembly 2 and illuminated, the light is vertically upward and enters the lower opening of the light guide cover 31, the light guide cover 31 makes the light diffuse evenly inside the cover, avoiding bright spots and dark areas; an indicator light sheet 5 is located at the upper opening of the light guide cover 31, the indicator light sheet 5 is detachably connected to the light guide cover 31, and an indicator groove 51 is provided on the side of the indicator light sheet 5 facing the light-emitting unit 4; when the light reaches the lower surface of the indicator light sheet 5, it first enters the indicator groove 51. The sidewalls of the groove form a light trap, where some light is reflected or scattered, thus creating a brighter pattern on the upper surface of the indicator light piece 5 that matches the shape of the groove. The indicator light piece 5 is detachably connected to the upper end of the light guide cover 31 via a snap, magnet, or slide rail; users can simply remove the old piece and insert the new one to change the indicator style, improving the user experience.

[0021] In practical use, the light guide cover 31 is used to convert the point light source into a surface light source, so that the light emitted by the light-emitting unit 4 can be evenly projected onto the indicator light sheet 5. The indicator light sheet 5 uses the indicator groove 51 to form a light trap, so that the pattern and the background have high contrast and are still clearly visible at long distances and wide viewing angles, thereby improving the user experience. In addition, the indicator light sheet 5 and the light guide cover 31 are detachably connected, which makes it easy for users to quickly assemble and disassemble the indicator light sheet 5 to meet the personalized use needs of users. Users can print or 3D print personalized indicator light sheets 5 in batches for different scenarios, reducing inventory and customization costs.

[0022] It should be noted that the light-emitting unit 4 can be an existing LED lamp core or a mini LED lamp core, and the driving component 2 is an existing LED driver. The specific structure and working principle are existing technologies and will not be described in detail here.

[0023] like Figures 1 to 7 As shown, further, the upper opening of the light guide cover 31 is provided with a slot 32 that is adapted to the indicator light piece 5; the indicator light piece 5 is inserted into the slot 32 at the upper opening of the light guide cover 31 from top to bottom, and the four sides of the slot 32 first radially position the indicator light piece 5 to ensure that the indicator light piece 5 is coaxial with the light guide cover 31.

[0024] Specifically, the bottom of the slot 32 is provided with at least one first latching groove 33, and the bottom of the indicator light piece 5 is provided with a first latching member 52 that engages with the first latching groove 33. The first latching member 52 at the bottom of the indicator light piece 5, such as an elastic barb or an elastic cantilever, undergoes elastic deformation and engages in the slot 32 when it encounters the first latching groove 33 at the bottom of the slot 32, forming an axial lock. At this time, the lower surface of the indicator light piece 5 and the light-emitting surface of the light guide cover 31 maintain a close fit gap, which ensures the continuity of the light path and avoids stress cracking caused by excessive tightness. When it is necessary to disassemble the indicator light piece 5, the user can use a thin tool to insert into the gap between the slot 32 and the indicator light piece 5 and pry the indicator light piece 5 to disengage the first latching member 52 from the first latching groove 33, and then pull the indicator light piece 5 upward to complete the quick replacement of the indicator light piece 5.

[0025] like Figures 1 to 7 As shown, the light guide hood 31 is further flared, with its lower opening gradually widening towards its upper opening. The light-emitting unit 4 is located at the lower opening of the light guide hood 31 with the smallest diameter. The light emitted by the approximate point light source first enters the narrow end of the flared light guide hood 31 at a relatively large solid angle. The inner wall of the flared opening is a continuous and smooth conical surface. The light undergoes continuous total internal reflection on the conical surface and is gradually flattened into a direction with a smaller angle to the axis of the light guide hood 31, eventually forming an approximately collimated uniform beam inside the hood. When the light reaches the upper opening of the flared opening, the beam diameter has been magnified to be the same as the effective area of ​​the indicator light piece 5. At this time, the light density decreases and the angle range is concentrated in the upper half of the region. Then, it is scattered or locally absorbed by the indicator groove 51 on the lower surface of the indicator light piece 5, forming a high-contrast indicator pattern without bright spots.

[0026] like Figures 1 to 7 As shown, the driving assembly 2 further includes a light source driving board 21, a power input board 22, and a terminal block 23. The terminal block 23 is disposed on the power input board 22 and is electrically connected to the power input board 22. The light source driving board 21 is disposed on the top of the power input board 22 and is electrically connected to the power input board 22. The light-emitting unit 4 is disposed on the light source driving board 21 and is electrically connected to the light source driving board 21. The power input board 22 is detachably connected to the mounting cavity. During installation, the power input board 22 is engaged with the guide groove on the side wall of the mounting cavity of the bottom shell 1 via spring tabs or slide rails on both sides. The light source driving board 21 is vertically inserted and removed from the power input board 22 using pins or a plate-to-plate socket, allowing the user to remove the light source driving board 21 first and then remove the power input board 22 during maintenance without disassembling the entire switch.

[0027] In use, the terminal block 23 is used to connect to the mains power terminal of the external power switch. When the power input board 22 receives the mains power, it will rectify and filter the mains power and convert it into low-voltage DC to meet the input requirements of the light source driver board 21. Then, the light source driver board 21 will step down or maintain constant current to drive the light-emitting unit 4 to work.

[0028] like Figures 1 to 7 As shown, further, one side of the mounting cavity is provided with a groove 11 along its height direction that matches the edge of the power input plate 22. On the other side of the mounting cavity, a retaining plate 12 is provided that abuts against the power input plate 22. During assembly, the left edge of the power input plate 22 is first aligned with the groove 11 along the height direction of the mounting cavity. The depth of the groove 11 and the thickness of the power input plate 22 form an interference fit, completely limiting the power input plate 22 in the left-right direction. As the power input plate 22 continues to slide downwards into the groove 11, its other edge will touch the retaining plate 12 on the other side of the mounting cavity. The front end of the retaining plate 12 has an inlet ramp. The edge of the power input plate 22 is pressed downwards along the ramp, allowing the retaining plate 12 to abut against the surface of the power input plate 22, thereby completing the installation of the power input plate 22.

[0029] In this embodiment, the upper opening of the slide groove 11 is flared. By setting the upper opening of the slide groove 11 to a flared shape, it is easier to insert the power input board 22 into the slide groove 11, avoiding the need for the user to repeatedly align the power input board 22 and the slide groove 11 during assembly.

[0030] like Figures 1 to 7 As shown, further, a support strip 13 is provided on the inner wall of the mounting cavity, which abuts against the bottom of the light source driving plate 21; the support strip 13 can effectively provide support for the light source driving plate 21, and avoid the problem of deformation of the light source driving plate 21 under the influence of gravity.

[0031] like Figures 1 to 7 As shown, further, the top of the power input plate 22 is provided with at least one positioning block 24, and the light source driving plate 21 is provided with a positioning hole 25 that cooperates with the positioning block 24. Before the light source driving plate 21 is vertically inserted into the power input plate 22, the positioning hole 25 on the light source driving plate 21 is aligned with the positioning block 24 protruding from the top of the power input plate 22. The front end of the positioning block 24 may be chamfered, which can automatically guide within the radial error range to ensure precise alignment with the positioning hole 25. When the light source driving plate 21 continues to press down, after the positioning block 24 is fully inserted into the positioning hole 25, the positioning connection between the light source driving plate 21 and the power input plate 22 is completed.

[0032] like Figures 1 to 7As shown, further, the outer wall of the bottom shell 1 is provided with a plurality of second fastening elements 14, and the upper shell 3 is provided with a plurality of second fastening grooves 34 that cooperate and connect with the second fastening elements 14. The upper shell 3 is roughly aligned with the second fastening elements 14 on the outer wall of the bottom shell 1 with its opening facing downwards. The inner sidewall of the upper shell 3 first contacts the second fastening element 14, guiding it to slightly deform outwards elastically. When the second fastening element 14 reaches the second fastening groove 34 on the sidewall of the upper shell 3, it elastically recovers, and the barb engages with the second fastening groove 34, completing axial and radial double locking. During disassembly, the user only needs to press the second fastening element 14 to disengage it from the second fastening groove 34, thus removing the upper shell 3 without damage, achieving tool-free maintenance.

[0033] like Figures 1 to 7 As shown, the outer wall of the upper shell 3 is further provided with a third fastener 35 for connecting with an external power switch; correspondingly, the power switch is provided with a fastening groove for connecting with the third fastener 35, and the third fastener 35 is used to realize the detachable connection between the upper shell 3 and the power switch.

[0034] This utility model also provides a power switch, including the indicator light described above.

[0035] In summary, the light guide cover 31 transforms the point light source into a surface light source, enabling the emitted light from the light-emitting unit 4 to be evenly projected onto the indicator light sheet 5. The indicator light sheet 5, through the indicator groove 51, constructs a light trap, resulting in high contrast between the pattern and the background, ensuring clear visibility even at long distances and wide viewing angles, thus enhancing the user experience. Furthermore, the indicator light sheet 5 and the light guide cover 31 are detachably connected, facilitating quick disassembly and installation by the user to meet personalized usage needs. Users can mass-produce indicator light sheets 5 for different scenarios, thereby reducing inventory and customization costs.
