[0045] Please see Figure 1 This application provides an electrical device, which includes a housing 100 and a light-transmitting plate 500, the light-transmitting plate 500 being embedded in the housing 100. Please refer to [link to relevant documentation]. Figure 2 , Figure 2 In order to be in Figure 1 A cross-sectional view at point AA.

[0046] Please see Figure 3 , Figure 3 for Figure 2 In the enlarged view at point B, the electrical equipment includes: such as... Figure 1 The housing 100 shown, as Figure 3 The first LED 200 and reflector 300 shown are included. The housing 100 has a receiving cavity 110 and a light outlet 120 communicating with the receiving cavity 110. The first LED 200 is installed in the receiving cavity 110. The reflector 300 is installed in the receiving cavity 110 and has a curved reflective surface 331. The reflective surface 331 is used to reflect the light emitted by the first LED 200 to the light outlet 120.

[0047] In the aforementioned electrical device, both the first LED 200 and the reflector 300 are housed within the receiving cavity 110 of the housing 100, and a light outlet 120 communicating with the receiving cavity 110 is formed on the housing 100. The reflector 300 has a curved reflective surface 331. The light emitted by the first LED 200 is reflected by the reflective surface 331 of the reflector 300 and then emitted through the light outlet 120. Because the reflective surface 331 is curved, the light emitted by the first LED 200 towards the reflective surface 331 is reflected by the reflective surface 331 and then emitted, thereby producing reflected light in different directions from the incident light in one direction. This makes the light in the indicator light bar continuous and uniform, allowing the indicator light bar of the electrical device to display changes in power in a uniform manner, improving the user experience of using the electrical device.

[0048] In this embodiment, please refer to Figure 3 The first LED 200 is located on the side of the reflective surface 331 near the light outlet 120. By placing the first LED 200 on the side of the reflective surface 331 near the light outlet 120, the light emitted by the first LED 200 is reflected by the reflective surface 331 and then emitted through the light outlet 120.

[0049] Specifically, the light-emitting surface of the first LED 200 faces the reflective surface 331.

[0050] In some embodiments, please refer to Figure 3 The center of the reflective surface 331 is located within the light outlet 120. By restricting the position of the center of the reflective surface 331 so that it is located within the light outlet 120, the light reflected by the reflective surface 331 can be emitted through the light outlet 120, thus ensuring the accuracy of light emission.

[0051] In this embodiment, please refer to Figure 3 The electrical equipment also includes a PCB board 400. A first LED bead 200 is mounted on the PCB board 400. The PCB board 400 has a first through-hole 410 connected to the light outlet 120. Light reflected by the reflective surface 331 passes sequentially through the first through-hole 410 and the light outlet 120. The center of the reflective surface 331 is located within the first through-hole 410. By setting up the PCB board 400, mounting the first LED bead 200 on it, and opening the first through-hole 410, the light emitted by the first LED bead 200 passes sequentially through the reflective surface 331, the first through-hole 410, and the light outlet 120 before being emitted. By ensuring that the center of the reflective surface 331 is located within the first through-hole 410, the light reflected by the reflective surface 331 can pass through the first through-hole 410 and be emitted, thus guaranteeing the accuracy of the light emission.

[0052] Specifically, please refer to Figure 3The size of the light-emitting port 120 is larger than the size of the first through hole 410. By limiting the size of the light-emitting port 120 and the size of the first through hole 410, the size of the light-emitting port 120 is made larger than the size of the first through hole 410, ensuring that the light transmitted from the first through hole 410 can be emitted through the light-emitting port 120.

[0053] In this embodiment, please refer to Figure 3 The reflective surface 331 protrudes to the side away from the first lamp bead 200. The reflective surface 331 is a smooth curved surface and protrudes to the side away from the first lamp bead 200, so that the light emitted by the first lamp bead 200 can undergo diffuse reflection on the reflective surface 331.

[0054] In other embodiments, the reflective surface 331 can be a curved surface of any shape, as long as it can reflect light. For example, the reflective surface 331 can be an S-shaped curved surface.

[0055] In this embodiment, please refer to Figure 5 The first LED chip 200 has multiple chips; please refer to [link / reference]. Figure 4 Multiple reflective surfaces 331 are provided, each corresponding to a single first LED 200, which are arranged at intervals along the same direction. This one-to-one correspondence between the multiple first LEDs 200 and the multiple reflective surfaces 331 ensures that light emitted from each first LED 200 can be directed towards its corresponding reflective surface 331. Furthermore, the arrangement of the multiple first LEDs 200 at intervals along the same direction facilitates observation by the user.

[0056] In this embodiment, the on / off state of the first LED 200 is used to indicate the power level of the electrical device. For example, when the first LED 200 is on, it indicates that the electrical device still has some power. When the first LED 200 is off, it indicates that the electrical device has no power.

[0057] Preferably, in this embodiment, please refer to Figure 5 The device has 10 first LED beads 200. If at least one of the 10 first LED beads 200 is lit, it indicates that the electrical device still has some power; if all 10 first LED beads 200 are off, it indicates that the electrical device has no power. In other embodiments, the number of first LED beads 200 is determined according to the actual operational needs.

[0058] Preferably, the number of lit first LED beads 200 corresponds one-to-one with the power reserve of the indicating device. Each lit first LED bead 200 indicates that the indicating device has 10% power. In this embodiment, if all 10 first LED beads 200 are lit, the indicating device has 100% power; if all 9 first LED beads 200 are lit, the indicating device has 90% power, and so on.

[0059] In other words, when all 10 first LED beads 200 are lit, that is, when the indicator light bar is fully lit, the corresponding indicator shows that the electrical device's power level is 100%. When one first LED bead 200 is turned off and nine first LED beads 200 are lit, that is, when 9 / 10 of the indicator light bar is lit, the corresponding indicator shows that the electrical device's power level is 90%. And so on. When all 10 first LED beads 200 are turned off, that is, when the indicator light bar is fully off, the corresponding indicator shows that the electrical device's power level is 0.

[0060] In this embodiment, please refer to Figure 4 The reflector cup 300 includes a substrate 310, a partition 320, and a plurality of reflective portions 330. The substrate 310 is arranged circumferentially around the partition 320 and the plurality of reflective portions 330. Each reflective portion 330 has a reflective surface 331, and adjacent reflective portions 330 are separated by the partition 320. By circumferentially arranging the substrate 310 around the partition 320 and the plurality of reflective portions 330, and by providing a partition 320 between adjacent reflective portions 330, the light reflected from adjacent reflective portions 330 is separated.

[0061] Specifically, the substrate 310, the partition 320, and the multiple reflective parts 330 are integrally formed.

[0062] Specifically, the partition 320 is configured to extend between two adjacent first LED beads 200. By using the partition 320 to separate two adjacent first LED beads 200, the light emitted by the two adjacent first LED beads 200 is split by the partition 320, thereby making the power level of each segment of the indicator light bar of the electrical device clearer.

[0063] In this embodiment, please refer to Figure 4 An obstacle avoidance groove 311 is provided on the side of the substrate 310 near the first lamp bead 200. The obstacle avoidance groove 311 is provided on the substrate 310 to avoid other electrical components of the PCB board 400 or the receiving cavity 110.

[0064] In this embodiment, the electrical device also includes a locking element; please refer to [link / reference]. Figure 4The reflector cup 300 includes a substrate 310 and a reflective portion 330. The substrate 310 is arranged circumferentially around the reflective portion 330, and the reflective portion 330 has a reflective surface 331. A positioning hole 312 is provided on the substrate 310, and a locking member passes through the positioning hole 312 and is connected to the cavity wall of the receiving cavity 110. By providing the locking member, and with the positioning hole 312 provided on the substrate 310, the locking member passes through the positioning hole 312 and is connected to the cavity wall of the receiving cavity 110, thereby installing the reflector cup 300 inside the receiving cavity 110.

[0065] Specifically, there are multiple positioning holes 312 and multiple locking parts, with each locking part corresponding to one of the multiple positioning holes 312.

[0066] Specifically, please refer to Figure 4 Multiple positioning holes 312 are arranged circumferentially around the substrate 310. By providing multiple positioning holes 312 and arranging them circumferentially around the substrate 310, multiple locking members passing through the positioning holes 312 are arranged circumferentially around the substrate 310. That is, locking members are provided circumferentially around the substrate 310 and connected to the cavity wall of the receiving cavity 110, which improves the connection strength and connection stability between the reflector cup 300 and the cavity wall of the receiving cavity 110.

[0067] In this embodiment, please refer back to the previous section. Figure 1 The electrical equipment also includes a light-transmitting panel 500, which is embedded in, for example... Figure 2 The light outlet 120 is shown. By embedding a light-transmitting plate 500 inside the light outlet 120, the light at the light outlet 120 can not only pass through the light-transmitting plate 500, but the light-transmitting plate 500 also blocks the light outlet 120 to prevent external dust or water droplets from flowing into the receiving cavity 110.

[0068] Further, in this embodiment, please refer to Figure 5 The electrical device also includes a second lamp 600 disposed within the receiving cavity 110. The housing 100 is provided with a light-transmitting groove, and the light-emitting surface of the second lamp 600 faces the light-transmitting groove. By setting the second lamp 600 so that its light-emitting surface faces the light-transmitting groove, the light emitted by the second lamp 600 can be displayed on the housing 100 through the light-transmitting groove.

[0069] Specifically, in this embodiment, multiple first LED beads 200 cooperate to indicate the power capacity of the electrical device, while second LED beads 600 indicate the power status (e.g., whether there is power) or the on / off status of the electrical device.

[0070] In this embodiment, please refer to Figure 5The electrical equipment also includes a PCB board 400. The first LED bead 200 and the second LED bead 600 are both mounted on the same side of the PCB board 400. The PCB board 400 has a first through hole 410 communicating with the light outlet 120 and a second through hole communicating with the light transmission groove. Light reflected by the reflective surface 331 passes sequentially through the first through hole 410 and the light outlet 120. The emitting surface of the second LED bead 600 faces the second through hole. The second through hole on the PCB board 400 allows the emitting surface of the second LED bead 600 to face the second through hole, and the second through hole is connected to the light transmission groove. The light emitted by the second LED bead 600 can pass sequentially through the second through hole and the light transmission groove before being displayed on the housing 100.

[0071] In this embodiment, the light-transmitting groove is a blind hole provided in the housing 100. By setting the light-transmitting groove as a blind hole, the light emitted by the second lamp bead 600 can be displayed on the housing 100 after passing through the second through hole and the light-transmitting groove.

[0072] In other implementations, the light-transmitting groove extends through the outer wall of the housing 100.

[0073] In this embodiment, please refer to Figure 5 The second LED 600 and multiple first LEDs 200 are on the same line. Both the first LEDs 200 and 600 are mounted on the PCB board 400, ensuring they are on the same line, i.e., the second LED 600 and multiple first LEDs 200 are arranged in a row. This collinearity between the first LEDs 200 and 600 facilitates installation of the second LED 600 and multiple first LEDs 200, improving installation convenience and efficiency.

[0074] In other embodiments, the second LED 600 and the plurality of first LEDs 200 are not collinear and can be located at any position on the PCB board 400.

[0075] In this embodiment, the light outlet 120 and the light transmission groove are disposed in the visible area of ​​the housing 100, wherein the visible area is the area on the housing 100 that can be seen by the user. By placing the light outlet 120 and the light transmission groove in the visible area, it is convenient for the user to observe them.

[0076] For details, please refer to the following: Figure 1 The housing 100 of this application has a cuboid structure, and the visible area includes the front, two sides and the top surface of the housing 100.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
