[0028] Please see Figures 1 to 4 This application provides a light-emitting component 40, including a light-transmitting element 41 and a plurality of dot-emitting elements 42 arranged sequentially at intervals. The light-transmitting element 41 has an incident surface 412a, a first reflecting surface 412b, a second reflecting surface 411b, and an exiting surface 411a. (See also...) Figure 4 The light-emitting surface 42a of the point light-emitting element 42 faces the incident surface 412a. Both the first reflecting surface 412b and the second reflecting surface 411b are chamfered surfaces. The incident surface 412a and the first reflecting surface 412b are arranged facing each other along a first direction A1, and the first reflecting surface 412b and the second reflecting surface 411b are arranged facing each other along a second direction A2. The second reflecting surface 411b and the light-emitting surface 42a are distributed along the first direction A1, and the first direction A1 and the second direction A2 form a predetermined angle. Light-diffusing powder is distributed within the light-transmitting element 41. Figure 5 The light emitted by the multiple point light-emitting elements 42 is incident on the incident surface 412a, and after being reflected by the first reflecting surface 412b and the second reflecting surface 411b in sequence, it is emitted out of the exit surface 411a.

[0029] The multiple point light-emitting elements 42 can be arranged sequentially at intervals along arcs, rings, straight lines, etc. The ring can be a circle, ellipse, rectangle, rounded rectangle, etc.

[0030] The chamfered surfaces (first reflecting surface 412b and second reflecting surface 411b) can be the side of a frustum or an inclined surface (plane).

[0031] The light-transmitting element 41 contains light-diffusing powder. When light shines on the light-diffusing powder, it will be refracted and scattered to diffuse the light in different directions, making the brightness of the light source more uniform and maintaining good light transmittance of the light-transmitting element 41.

[0032] The light-emitting component 40 provided in this application embodiment has a folded light path in the light-transmitting element 41, achieving a longer light transmission distance in a limited space. The incident surface 412a and the first reflecting surface 412b of the light-transmitting element 41 face each other along the first direction A1, and the first reflecting surface 412b and the second reflecting surface 411b face each other along the second direction A2. The second reflecting surface 411b and the light-emitting surface 42a are distributed along the first direction A1. Both the first reflecting surface 412b and the second reflecting surface 411b are chamfered surfaces. The point light-emitting element 42 emits a point light source within a certain angle range and is incident on the incident surface 412a. The light is reflected by the first reflecting surface 412b and the second reflecting surface 411b, which can extend the light path distance in a small space. Combined with the light-diffusing powder in the light-transmitting element 41, the light is diffused evenly, increasing the light diffusion effect and transforming the point light source of the point light-emitting element 42 into a surface light source emitted from the light-emitting surface 411a. The emitted light portions formed by two adjacent point light emitters 42 on the emission surface 411a overlap, thereby achieving uniform light emission from the emission surface 411a.

[0033] In some embodiments, please refer to Figure 1 , Figure 2 The light-emitting element 42 can be an LED lamp bead, which can be set on the circuit board 43 to facilitate the assembly and control of multiple LED lamp beads.

[0034] In some embodiments, please refer to Figure 1 , Figure 2 The light-transmitting component 41 can be an optical resin component, such as polycarbonate (PC) or epoxy resin. When manufacturing the light-transmitting component 41, light-diffusing powder is added to the material of the light-transmitting component 41, and the light-transmitting component 41 with internally distributed light-diffusing powder is obtained through injection molding.

[0035] For example, the light-transmitting element 41 is made of white translucent optical resin and light-diffusing powder.

[0036] In some embodiments, please refer to Figure 4The point light-emitting element 42 and the emitting surface 411a are distributed along the second direction A2. This makes the overall structure of the light-emitting assembly 40 compact and occupies less space. This allows the light-emitting assembly 40 to be used in space-constrained scenarios, such as small electronic devices.

[0037] In some embodiments, please refer to Figures 1 to 4 The light-transmitting element 41 is annular, with the first direction A1 being the radial direction of the light-transmitting element 41 and the second direction A2 being parallel to the axial direction of the light-transmitting element 41; the emission surface 411a extends along the annular shape; the incident surface 412a and the first reflecting surface 412b are arranged sequentially outward along the radial direction of the light-transmitting element 41; the emission surface 411a and the second reflecting surface 411b are arranged sequentially outward along the radial direction of the light-transmitting element 41; a plurality of point light-emitting elements 42 are distributed in annular shape, and the light-emitting surface 42a of the point light-emitting elements 42 is arranged outward along the radial direction of the light-transmitting element 41.

[0038] Here, "radially outward along the light-transmitting element 41" means the direction away from the center of the light-transmitting element 41 along its radial direction.

[0039] The annular light-transmitting element 41, combined with multiple annularly arranged point-emitting elements 42, enables uniform light emission from the annular exit surface 411a. Light emitted from the point-emitting elements 42 enters through the incident surface 412a, is reflected by the first reflecting surface 412b and the second reflecting surface 411b, and, combined with the refraction and scattering of light by the light-diffusing powder within the light-transmitting element 41, is uniformly emitted from the exit surface 411a. The emitted light from two adjacent point-emitting elements 42 partially overlaps on the exit surface 411a, reducing the dark area between the emitted light from adjacent point-emitting elements 42, thus achieving uniform light emission throughout the entire annularly extended exit surface 411a.

[0040] For example, the point light-emitting element 42 is an LED lamp bead. There are 10 point light-emitting elements 42 arranged in a circle or rounded rectangle, and each point light-emitting element 42 emits light from the side. The thickness of the light-transmitting element 41 in the second direction A2 is 6 mm. The combination of multiple point light-emitting elements 42 with the light-transmitting element 41 containing light-diffusing powder enables uniform light emission from the entire circumference of the light-transmitting element 41's emission surface 411a.

[0041] In some embodiments, please refer to Figures 1 to 4 The light-transmitting element 41 includes an annular portion 411 and a plurality of reflective portions 412, which are arranged in a ring and connected to the annular portion 411. A second reflective surface 411b and an exit surface 411a are formed on the surface of the annular portion 411. Each reflective portion 412 forms an incident surface 412a and a first reflective surface 412b. The light-emitting surfaces 42a of the plurality of point light-emitting elements 42 are arranged facing the incident surfaces 412a of the plurality of reflective portions 412 respectively.

[0042] The shape of the annular portion 411, the arrangement of the multiple reflective portions 412, and the arrangement of the multiple point light-emitting elements 42 are adapted to each other. The annular portion can be circular, elliptical, rectangular, rounded rectangle, or other shapes.

[0043] The light-transmitting element 41, employing a ring-shaped portion 411 and multiple reflective portions 412, occupies less space and has a compact structure. Figure 5 The point light source emitted by the point light-emitting element 42 enters the incident surface 412a of the corresponding reflector 412. When the light passes through the light-diffusing powder inside the light-transmitting element 41, it is refracted and scattered, thus diffusing the light in different directions. It is reflected at the first reflective surface 412b of the reflector 412, then reflected at the second reflective surface 411b of the annular portion 411, and then uniformly emitted at the exit surface 411a.

[0044] In some embodiments, please refer to Figures 1 to 4 The incident surface 412a and the first reflecting surface 412b are both planar, and the second reflecting surface 411b extends along a ring. This makes the light-transmitting element 41 easy to process. The light emitted by the point light-emitting element 42 is reflected on the first reflecting surface 412b after passing through the incident surface 412a, and then reflected by the ring-shaped second reflecting surface 411b before finally exiting at the exit surface 411a.

[0045] In some embodiments, please refer to Figures 1 to 4 It also includes a circuit board 43, on which multiple point light-emitting elements 42 are disposed and electrically connected to the circuit board 43. This facilitates the assembly and control of the multiple point light-emitting elements 42.

[0046] In some embodiments, please refer to Figures 1 to 4 The circuit board 43 is ring-shaped, and multiple point light-emitting elements 42 distributed in the ring can be mounted on the ring-shaped circuit board 43. Pre-defined components (such as speakers) can be arranged in the inner holes of the circuit board 43, improving space utilization. The shape of the circuit board 43 is adapted to the shape of the light-transmitting element 41, for example, both can be ring-shaped or rounded rectangles.

[0047] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 The emitting surface 411a includes a first sub-emitting surface 411a1 and a second sub-emitting surface 411a2. The first sub-emitting surface 411a1 and the second reflecting surface 411b are arranged facing each other along the first direction A1. The second sub-emitting surface 411a2 is connected between the second reflecting surface 411b and the first sub-emitting surface 411a1. Light rays are emitted through the first sub-emitting surface 411a1 and the second sub-emitting surface 411a2, giving the light emitting assembly 40 a better light emission effect.

[0048] In some embodiments, please refer to Figure 4In the second direction A2, the thickness of the light-transmitting element 41 ranges from 5 mm to 10 mm. By setting the light-transmitting element 41 to a relatively small thickness, the point light-emitting element 42, combined with the light-transmitting element 41 containing light-diffusing powder, can convert the point light source of the point light-emitting element 42 into a surface light source output from the light-transmitting element 41. The overall structure is very thin and can be applied in scenarios with limited space.

[0049] In other embodiments, the light-transmitting element extends in a straight line and has a length direction, a width direction, and a height direction. The first direction can be the width direction of the light-transmitting element, and the second direction can be the height direction of the light-transmitting element; the emitting surface extends along the length direction of the light-transmitting element; the incident surface and the first reflecting surface are arranged along the width direction of the light-transmitting element; the emitting surface and the second reflecting surface are arranged along the width direction of the light-transmitting element; multiple point light-emitting elements are linearly distributed, and the light-emitting surface of the point light-emitting elements is arranged along the width direction of the light-transmitting element.

[0050] A linearly extending light-transmitting element combined with multiple linearly arranged point-emitting elements enables uniform light emission from a linearly extending exit surface. Light emitted from the point-emitting elements enters through the incident surface, is reflected by the first and second reflecting surfaces, and, combined with the refraction and scattering of light by the light-diffusing powder within the light-transmitting element, ensures uniform light emission from the exit surface. The emitted light from two adjacent point-emitting elements partially overlaps, reducing the dark areas between the emitted light from adjacent point-emitting elements and achieving uniform light emission from the linearly extending exit surface.

[0051] In other embodiments, the light-transmitting element extends in a straight line, and multiple point-emitting elements are arranged sequentially at intervals along the straight line. The light-transmitting element includes a straight section and multiple reflective sections, which are linearly distributed and connected to the straight section. The surface of the straight section forms a second reflective surface and an emission surface, and each reflective section forms an incident surface and a first reflective surface. The emission surfaces of the multiple point-emitting elements are arranged one-to-one facing the incident surfaces of the multiple reflective sections. The incident surface, the first reflective surface, and the second reflective surface are planar.

[0052] This light-transmitting component, employing a straight section and multiple reflective sections, occupies a small space and has a compact structure. A point light source emitted by the point light-emitting component enters the incident surface of the corresponding reflective section. As the light passes through the light-diffusing powder inside the light-transmitting component, it undergoes refraction and scattering, achieving light diffusion in different directions. The light is reflected at the first reflective surface of the reflective section, then at the second reflective surface of the straight section, and finally emitted uniformly at the exit surface.

[0053] This application provides an electronic device including the light-emitting component 40 described above. Since this electronic device employs all the technical solutions of all the above embodiments, it also possesses all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.

[0054] In some embodiments, the electronic device can be a wearable speaker, which is small in size and multifunctional. The wearable speaker can be a Bluetooth speaker capable of high-volume playback; it can have a walkie-talkie communication module for group chat; it can have a flashlight for illumination; and it can have a built-in storage chip for storing audio files. Wearable speakers are suitable for outdoor scenarios such as hiking and cycling.

[0055] In some embodiments, the electronic device includes a housing, within which a speaker is housed. A plurality of point light-emitting elements 42 in the light-emitting assembly 40 are disposed on a circuit board 43, and the circuit board 43 and a light-transmitting element 41 are disposed in the housing. The circuit board 43 is annular, and the speaker is located at the inner hole of the circuit board 43. Sound is output to the outside from the speaker, and light is emitted to the outside from the light-emitting assembly 40, resulting in a compact overall structure.

[0056] In some embodiments, the light-emitting component 40 can serve as an ambient light for an electronic device, providing the user with a predetermined lighting effect.

[0057] The above are only preferred embodiments of the present application and are not intended to limit the present application.
