[0002] Mobile phone light strips are typically installed on the back of mobile phones, primarily for call notifications, message alerts, game interaction, charging status indication, music synchronization, and personalized decoration. Current mainstream mobile phone light strips mainly use a distributed arrangement of multiple LEDs, combined with a single circular or long strip of transparent light guide lens with a frosted finish to transmit light. However, this method suffers from uneven brightness and glare when the LEDs are lit. Furthermore, the dispersed placement of the LEDs requires excessive structural space within the phone, hindering the overall slim and lightweight design. Utility Model Content

[0008] Optionally, a light-shielding film is also included, disposed on the side of the light guide plate near the light-transmitting element, and corresponding to the position of the light-emitting component.

[0017] Optionally, the light-transmitting element is the battery cover or camera lens of the electronic device.
[0018] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:
[0019] As can be seen from the above embodiments, the LED strip module disclosed herein places the light-emitting component on one side of the light guide plate. Through the optical cavity structure in the light guide plate, the light emitted by the light-emitting component is refracted toward the light-transmitting component and emitted from the light-transmitting hole of the light-transmitting component. This solves the problem in the prior art where the LED beads are placed in a dispersed manner, resulting in a large amount of structural space being occupied.
[0020] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description
[0021] The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments consistent with this disclosure and, together with the description, serve to explain the principles of this disclosure.
[0022] Figure 1 This is a side sectional view of a light strip module according to an exemplary embodiment.
[0023] Figure 2 This is a top view of a light strip module according to an exemplary embodiment. Detailed Implementation
[0024] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0025] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.
[0026] To facilitate understanding of the technical solutions of this disclosure, the LED strip module and electronic equipment of this disclosure will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features in the following embodiments and implementations are interchangeable.
[0027] See Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides a light strip module that can be used in electronic devices, including: a light-emitting component 10, a light guide component 20, and a light-transmitting component 30.
[0028] The light-transmitting element 30 is provided with a light-transmitting hole 31. The light-guiding assembly 20 includes a light-guiding plate 21 and an optical cavity structure 22. The light-emitting element 10 is disposed on one side of the light-guiding plate 21. The light-transmitting element 30 is disposed on the other side of the light-guiding plate 21. The optical cavity structure 22 is disposed within the light-guiding plate 21 and is used to refract the light emitted by the light-emitting element 10 towards the light-transmitting element 30. Optionally, the optical cavity structure 22 can be a prism, such as a triangular prism, the surface of which can be textured to better refract light. It can also be other optical structures capable of achieving light refraction.
[0029] When the light strip assembly is applied to an electronic device, the light-transmitting element 30 can be a battery cover or camera lens on the back of the electronic device. That is, the light-transmitting element 30 can be understood as being located on the outside of the light guide plate 21, and the light-emitting component 10 can be understood as being located on the inside of the light guide plate 21. The light-emitting component 10 can be soldered onto the flexible circuit board of the electronic device. The light-emitting component 10 emits light through the power supply of the electronic device. The light-emitting component 10 can emit light of different colors. After being refracted within the light guide plate 21 by the optical cavity structure 22 of the light guide component 20, the light is emitted from the light-transmitting hole 31 of the light-transmitting element 30. The path of the light is as follows... Figure 1 As shown by the middle arrow, this forms a light strip on the surface of the electronic device, which can be used for functions such as call notifications, message reminders, game interaction, charging status indication, music rhythm synchronization, and personalized decoration. This solves the problem of the dispersed placement of the LED beads in existing technologies, which results in a large space occupation.
[0030] In some optional embodiments, the LED strip module may further include a light-diffusing film 40 disposed on the side of the light guide plate 21 near the light-transmitting element 30. The light-diffusing film 40 is used to uniformly guide the light passing through the surface of the light guide plate 21 near the light-transmitting element 30 toward the light-transmitting element 30. Optionally, the light-diffusing film 40 is attached to the surface of the light guide plate 21. It is understood that the light emitted by the light-emitting component 10, after being refracted by the light guide component 20, can be uniformly directed toward the light-transmitting element 30, improving the uniformity of the light emitted from the light-transmitting hole 31 of the light-transmitting element 30, as well as the softness of the light, solving the problem of dispersed LED positions and glaring, harsh light in the prior art.
[0031] In some optional embodiments, the LED strip module may also include a reflective film 50 disposed on the side of the light guide plate 21 near the light-emitting component 10. The reflective film 50 is used to reflect light passing through the surface of the light guide plate 21 near the light-emitting component 10 towards the surface of the light guide plate 21 near the light-transmitting element 30. Optionally, the reflective film 50 is attached to the surface of the light guide plate 21. It is understood that inside the light guide plate 21, some light rays, after being refracted by the optical cavity structure 22, are directed towards the light-transmitting element 30. Another portion of the light rays, after being refracted by the optical cavity structure 22, may not be directed towards the light-transmitting element 30, but rather away from it. By providing a reflective film 50 on the side of the light guide plate 21 near the light-emitting component 10, this portion of light rays that is not directly refracted towards the light-transmitting element 30 can be reflected and refracted back towards the light-transmitting element 30 after being reflected by the reflective film 50.
[0032] It should be noted that the light guide plate 21 is covered with a reflective film 50. The surface of the light guide plate 21 faces the light-emitting component 10, and a notch can be provided corresponding to the position of the light-emitting component 10 to allow light emitted from the light-emitting component 10 to pass through.
[0033] In some optional embodiments, the LED strip module may further include a light-shielding film 60 disposed on the side of the light guide plate 21 near the light-transmitting element 30 and corresponding to the position of the light-emitting component 10. This prevents excessive brightness on the surface of the light guide plate 21 near the light-transmitting element 30 at the position corresponding to the light-emitting component 10, thus achieving higher uniformity. Optionally, the light-shielding film 60 may be a black light-shielding reflective film attached to the surface of the light guide plate 21.
[0034] In some optional embodiments, the light-transmitting element 30 has an opaque ink layer at the position where the light-transmitting hole 31 is not located, and a hidden ink layer is located at the position corresponding to the light-transmitting hole 31. Optionally, the large surface of the light-transmitting element 30 with the light-transmitting hole 31 can be screen-printed with opaque ink, and the opening position of the light-transmitting hole 31 can be screen-printed with hidden ink, i.e., semi-transparent ink. In this way, when the light-emitting component 10 is not lit, the user cannot see the internal light strip structure of the electronic device, achieving visual consistency of the electronic device. When the light-emitting component 10 is lit, the light is emitted uniformly from the light-transmitting hole 31, achieving the effect of notification or interaction. Optionally, the opaque ink layer and the hidden ink layer can be located on the surface of the light-transmitting element 30 near the light guide plate 21.
[0035] Optionally, the optical cavity structure 22 is located in the middle of the light guide plate 21, and the light-emitting component 10 is disposed corresponding to the optical cavity structure 22. It can be understood that since the optical cavity structure 22 is located in the middle of the light guide plate 21, the light-emitting component 10 corresponds to the middle position of the light guide plate 21, and the light-shielding film 60 corresponds to the middle position of the surface of the light-emitting component 10 attached to the light guide plate 21.
[0036] In some alternative implementations, combined with Figure 2 As shown, the projection of the light guide plate 21 onto the light-transmitting component 30 covers the light-transmitting hole 31. This ensures that the light emitted by the light-emitting component 10, after refraction by the light guide component 20, can exit through the light-transmitting hole 31 of the light-transmitting component 30. Optionally, the light-transmitting hole 31 is an annular hole. In this embodiment, there are two light-transmitting holes 31, symmetrically arranged on both sides of the light-emitting component 10. The light emitted by the light-emitting component 10, after refraction by the light guide component 20, can exit evenly from the two light-transmitting holes 31. It should be noted that when the light-transmitting component 30 is the lens of a camera on the back of an electronic device... Figure 2 The light-transmitting hole 31 is an annular hole, and the circular area 70 inside the annular hole 31 can be used to install a camera.
[0037] In some alternative implementations, combined with Figure 1 and Figure 2 As shown, the light-emitting component 10 includes a plurality of LED beads 11, the plurality of LED beads 11 corresponding to the optical cavity structure 22 along a first direction ( Figure 2 (As shown in the diagram, the lamp beads are arranged side by side in a longitudinal direction.) Optionally, the lamp beads 11 can be LED lamp beads. By setting an optical cavity structure 22 within the light guide plate 21, all the lamp beads 11 can be arranged close together on the same side of the light guide plate 21, resulting in a concentrated position and a small structural space occupation. The light emitted by each lamp bead 11 can be refracted by the optical cavity structure 22 and emitted from the light transmission hole 31 of the light transmission element 30.
[0038] Optionally, there are multiple light-transmitting holes 31, arranged along the second direction ( Figure 2 The lamp beads (shown as horizontally spaced) are arranged in a second direction perpendicular to the first direction. Although the positions of the lamp beads 11 and the light-transmitting holes 31 are not corresponding, this disclosure allows all the lamp beads 11 to be arranged close together on the same side of the light guide plate 21 by setting an optical cavity structure 22 inside the light guide plate 21. The light emitted by each lamp bead 11 can be refracted by the optical cavity structure 22 and emitted from the light-transmitting hole 31 of the light-transmitting element 30.
[0039] The disclosed LED strip module allows light emitted by the light-emitting component to be refracted within the light guide plate after passing through the optical cavity structure of the light guide component, and then emitted through the light-transmitting hole of the light-transmitting component. Multiple LEDs of the light-emitting component can be placed close together on the same side of the light guide plate. Through optical designs such as attaching a light-shielding film, a reflective film, and a light-diffusing film to the light guide plate, and screen-printing opaque ink and concealing ink (semi-transparent ink) on the light-transmitting component, the module achieves uniform brightness, small footprint, soft light, and a semi-concealed LED strip effect. This solves the problems of uneven brightness, large structural space occupation due to dispersed LED positions, and glaring, harsh light in existing LED strips used in mobile phones and other electronic devices.
[0040] This disclosure also provides an electronic device, including a light strip module as described in the above embodiments and implementations. Optionally, the light-transmitting element 30 of the light strip module can be a battery cover or a camera lens of the electronic device. The electronic device can be an electronic product such as a mobile phone, tablet computer, or wearable device.
[0041] In the electronic device disclosed herein, the light-emitting component 10 can emit light of different colors. After being refracted within the light guide plate 21 by the optical cavity structure 22 of the light guide component 20, the light is emitted from the light-transmitting hole 31 of the light-transmitting component 30. The path of the light is as follows: Figure 1 As shown by the middle arrow, this forms a light strip on the surface of the electronic device, which can be used for functions such as call notifications, message reminders, game interaction, charging status indication, music rhythm synchronization, and personalized decoration. This solves the problem of the dispersed placement of the LED beads in existing technologies, which results in a large space occupation.
[0042] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
