Detailed Description of Embodiments

[0023] Embodiments of the present disclosure are described in detail below in conjunction with the drawings. The same or similar reference numerals in the drawings indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the drawings are exemplary and are intended merely to explain the present disclosure, and shall not be understood as limitations of the present disclosure.

[0024] Unless otherwise defined, the technical terms or scientific terms used here should be the ordinary meanings understood by those of ordinary skill in the field of the present disclosure. In the description of the present disclosure, it should be understood that an orientation or positional relationship indicated by the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," etc. is an orientation or positional relationship shown based on the accompanying drawings, is only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that a device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present disclosure. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be construed as indicating or implying relative importance.

[0025] The present disclosure provides a lighting assembly, including: an elongated light source panel provided with a plurality of light sources arranged along its longitudinal direction; an elongated reflector spaced apart from and arranged to face the light source panel and including a plurality of reflective structures arranged along its longitudinal direction; and a light diffuser, made of a translucent material, surrounding the light source panel and the reflector laterally, and having an inner surface extending between the light source panel and the reflector and an outer surface opposite to the inner surface.

[0026] In such a lighting assembly, light emitted by the elongated light source panel is uniformly distributed in the longitudinal direction of the lighting assembly through reflection by the reflective structure on the reflector. In addition, the light emitted from the light sources of the light source panel (after being reflected by the reflector) enters the light diffuser from the inner surface of the light diffuser and exits from the outer surface thereof. The translucent material of the light diffuser makes the light emitted by the light sources of the light source panel further uniformly distributed in the longitudinal direction of the lighting assembly.

[0027] According to one or more embodiments of the present disclosure, the plurality of reflective structures include a plurality of first reflective structures, each first reflective structure corresponding to one light source on the light source panel and arranged to face directly the corresponding light source. According to one or more embodiments of the present disclosure, the plurality of reflective structures further include a plurality of second reflective structures, the second reflective structure being arranged between two adjacent first reflective structures. The reflector configured in this way enables light emitted by the elongated light source panel to be further uniformly distributed in the longitudinal direction of the lighting assembly.

[0028] According to one or more embodiments of the present disclosure, the reflector is a formed part coated with a reflective coating. The reflector made in this way has the advantages of simple process, low cost and small thickness, thereby reducing the cost and volume of the lighting assembly.

[0029] The present disclosure provides an electronic device (e.g., a speaker box), including: a housing of the electronic device; a lighting assembly as described above, where the lighting assembly is mounted to the housing of the electronic device, and the housing of the electronic device has a transparent housing portion, with the outer surface of the light diffuser optically coupled to the transparent housing portion of the housing of the electronic device.

[0030] Through the optical coupling between the outer surface of the light diffuser of the lighting assembly and the transparent housing portion of the housing of the electronic device, the light exited from the outer surface of the light diffuser enters the transparent housing portion of the housing of the electronic device through the optical coupling, thereby realizing the lighting effect on the whole transparent housing portion of the housing of the electronic device. This improves the user experience.

[0034] The lighting assembly 100 includes an LED panel 110, a light diffuser 130, a reflector 150, a support ridge 170, and a back cover 190. In the embodiment shown in the figure, the lighting assembly 100 has an elongated shape such that its LED panel 110, light diffuser 130, reflector 150, support ridge 170, and back cover 190 all have an elongated shape.

[0035] The LED panel 110 includes a circuit board 112 and a plurality of LED elements 120 arranged on the circuit board 112. In one or more embodiments according to the present disclosure, the plurality of LED elements 120 of the LED panel 110 are arranged at intervals in the longitudinal direction of the LED panel 110. A plurality of holes 114 are also arranged on the LED panel 110 for fixedly positioning the LED panel 110. The light diffuser 130 includes a light diffuser body 132 and a plurality of holes 134 formed on the light diffuser body 132. The light diffuser 130 also includes a plurality of openings 140 arranged at intervals in the longitudinal direction of the lighting assembly 100. The light diffuser 130 is made of a light-transmissive material, such as a translucent material or a transparent material, for diffusing light ray transmitted therethrough. In some embodiments, dispersed diffusing particles are also formed within the light diffuser 130 for further diffusing the light ray transmitted therethrough. In one or more embodiments, the light diffuser 130 may be made of any material suitable for diffusing or scattering the light ray transmitted therethrough. The reflector 150 includes a reflector body 152, a plurality of holes 154 formed on the reflector body 152, and a plurality of reflective structures 160 formed on the reflector body 152. The support ridge 170 includes a support ridge body 172 and a plurality of holes 174 formed on the support ridge body 172. The back cover 190 includes a back cover body 192.

[0036] As shown in the figures, the plurality of holes 114 of the LED panel 110, the plurality of holes 134 of the light diffuser 130, the plurality of holes 154 of the reflector 150, and the plurality of holes 174 of the support ridge 170 are of the same number and in corresponding positions such that in an assembled position of the speaker box device 10 or the lighting assembly 100, the holes 114, 134, 154 and 174 of the LED panel 110, the light diffuser 130, the reflector 150, and the support ridge 170 are in aligned positions. Fasteners (not shown), such as screws, may pass through the holes 114, 134, 154 and 174 of the LED panel 110, the light diffuser 130, the reflector 150, and the support ridge 170 and are threaded into respective threaded holes 44 of the speaker box housing 20 to fasten the LED panel 110, the light diffuser 130, the reflector 150, and the support ridge 170 to the speaker box housing 20 of the speaker box device 10. Herein, the length direction of the lighting assembly 100 may be referred to as the longitudinal direction thereof. The direction in which the LED panel 110, the light diffuser 130, the reflector 150, the support ridge 170 and the back cover 190 are stacked together, i.e., the direction in which the fasteners extend in the illustrated embodiment, may be referred to as the front-rear direction, where the direction towards the speaker 14 is a forward direction and the direction away from the speaker 14 is a backward direction. The direction perpendicular to both the longitudinal direction and the front-rear direction of the lighting assembly 100 may be referred to as the lateral direction.

[0037] The speaker box housing 20, specifically the rear housing 22 of the sound box housing 20, is formed with an open pore 30 shaped and sized to be adapted to the lighting assembly 100. When the lighting assembly 100 is connected to the speaker box housing 20, the speaker box housing 20 and the lighting assembly 100 form a continuous outer surface, providing an aesthetically pleasing appearance. A recess 178 is formed on the back of the support ridge 170. The recess 178 of the support ridge 170 is shaped and sized to correspond to the back cover 190. When the back cover 190 is connected to the support ridge 170, it can cover screws or the like that connect the lighting assembly 100 to the speaker box housing 20 and forming a continuous outer surface with the support ridge 170, providing an aesthetically pleasing appearance.

[0038] Fig. 4A is a perspective sectional view of a speaker box device 10 according to one or more embodiments of the present disclosure; Fig. 4B is a partial enlarged view of the speaker box device 10 of Fig. 4A; and Fig. 4C is a partial view of the speaker box device 10 of Fig. 4A; where some components of the lighting assembly are in a separated state from each other to more clearly show the internal structure of the lighting assembly 100.

[0039] As shown in the figures, in the lighting assembly 100, the LED element 120 on the LED panel 110 faces the reflective structure 160 on the reflector 150. The LED panel 110 includes a plurality of LED elements 120 arranged at intervals in the longitudinal direction of the lighting assembly 100. The reflector 150 includes a plurality of reflective structures 160 spaced apart in the longitudinal direction of the lighting assembly 100. In the assembled position of the lighting assembly 100, each LED element on the LED panel 110 is aligned with a reflective structure 160 on the reflector 150, as shown in dashed lines in Figs. 4B and 4C. In the embodiment shown in the figure, the reflective structure 160 of the reflector 150 has a V-shaped structure with the vertices of the V-shaped structure facing directly the LED elements on the LED panel 110. Thus, when the LED element 120 emits light, the light emitted by it can be reflected by the reflective structure 160 facing it directly. Such reflection makes the light emitted by the LED elements 120 on the LED panel 110 more uniformly distributed, and in particular makes the light more uniformly distributed in the longitudinal direction of the lighting assembly 100. In one or more embodiments according to the present disclosure, the number of reflective structures 160 on the reflector 150 is greater than the number of LED elements 120 on the LED panel 110, so that some reflective structures 160 on the reflector 150 are not arranged in positions facing the LED elements 120 on the LED panel 110, but are arranged between two adjacent LED elements on the LED panel 110. In one or more embodiments according to the present disclosure, the reflector 150 may include one or two reflective structures 160 arranged at a position between two adjacent LED elements on the LED panel 110. The reflective structure 160 arranged at a position between two adjacent LED elements 120 on the LED panel 110 also serves to reflect light emitted by the LED elements so that the light emitted by the LED elements 120 on the LED panel 110 is more uniformly distributed. This configuration enables the lighting assembly 100 to obtain uniformly distributed light using a smaller number of LED elements 120, reducing its manufacturing and use costs.

[0040] According to one or more embodiments of the present disclosure, the reflector 150 is a formed part coated with a reflective coating. In some embodiment, the reflector 150 is formed by a formed plastic part coated with a reflective coating. In some other embodiments, the reflector 150 is formed by a stamped sheet metal which is preferably coated with a reflective coating. The reflector 150 thus manufactured has the advantages of simple process, low cost, and small thickness. In one or more other embodiments according to the present disclosure, the reflector 150 may be made by any suitable process. In one or more embodiments according to the present disclosure, the reflective structure 160 of the reflector 150 has a V-shaped cross-section for reflecting light emitted from the LED element 120 so that it is more uniformly distributed in the longitudinal direction of the lighting assembly 100. In one or more other embodiments according to the present disclosure, the reflective structure 160 of the reflector 150 may have any suitable structure and shape. In one or more embodiments according to the present disclosure, the reflector 150 includes one or two reflective structures 160 arranged at a position between two adjacent LED elements on the LED panel 110. In one or more other embodiments according to the present disclosure, the reflector 150 includes no reflective structure 160 at a position between two adjacent LED elements on the LED panel 110.

[0041] Fig. 5A is a partial sectional view of the speaker box device 10 taken along the longitudinal direction of the lighting assembly 100; and Fig. 5B is an enlarged view at the dashed box A in Fig. 5A. As shown in the figures, in the assembled position of the lighting assembly 100, the LED elements 120 of the LED panel 110 face directly the corresponding reflective structures 160 on the reflector 150 and are spaced apart from them by a distance. In one or more embodiments according to the present disclosure, the LED elements 120 of the LED panel 110 are located away from the corresponding reflective structures 160 on the reflector 150 by a small distance, e.g., 2mm-5mm, preferably 3-4mm. At such a distance, a great part of the light emitted from the LED elements 120 of the LED panel 110 is reflected by the corresponding reflective structures, so that the light emitted from the LED elements 120 is more uniformly distributed in the longitudinal direction of the lighting assembly 100. At the same time, this configuration allows a small thickness of the lighting assembly 100 in the front-rear direction, reducing the mounting space thereof.

[0042] According to one or more embodiments of the present disclosure, the light diffuser 130 includes a plurality of openings 140 arranged at intervals in the longitudinal direction of the lighting assembly 100 (see Figs. 2A-2B). The light diffuser 130 is arranged such that the light diffuser body 132 surrounds the LED panel 110 and the reflector 150 laterally or on the lateral sides and each opening 140 of the light diffuser 130 is aligned with corresponding one or more LED elements 120 on the LED panel 110, so that the light emitted by the LED element 120 can be incident unimpeded on the reflector 150, such as the reflective structure 160 of the reflector 150, and thus reflected by the reflector 150.

[0043] Fig. 6A is a sectional view of the speaker box device 10 taken along a plane perpendicular to the longitudinal direction of the lighting assembly 100; and Fig. 6B is an enlarged view at the dashed box in Fig. 6A. As shown in the figures, the LED panel 110 of the lighting assembly 100 and its LED elements 120 are spaced apart from the reflector 150, defining a reflection space 128 therebetween. Both sides of the reflection space 128 are surrounded and defined by the light diffuser 130 (the light diffuser body 132).

[0044] In one or more embodiments of the present disclosure, the LED element 120 of the LED panel 110 emits light, such as a divergent or tapered light beam. After the light emitted by the LED element 120 is reflected by the reflector 150 (e.g., the reflective structure 160), a part of the light enters the light diffuser body 132 through the inner surface 142 of the light diffuser body 132 and exits through the outer surfaces 144 and 146 of the light diffuser body 132. According to one or more embodiments of the present disclosure, the light diffuser 130 is made of a light-transmissive material, such as a translucent material or a transparent material, so that light transmitted therethrough can be diffused. In some embodiments, dispersed diffusing particles are also formed within the light diffuser 130 for further diffusing the light transmitted therethrough.

[0045] According to one or more embodiments of the present disclosure, the light diffuser body 132 of the light diffuser 130 forms a shoulder or step portion 142 on an outer side thereof. The shoulder or step portion 142 of the light diffuser 130 is configured to cooperate with a corresponding structure on the rear housing 22 of the speaker box housing 20 of the speaker box device 10, thereby realizing accurate positioning between the light diffuser 130 and the rear housing 22 of the speaker box housing 20. At this time, the outer surface 144 and the outer surface 146 of the light diffuser body 132 of the light diffuser 130 are closely adjacent to and facing the corresponding surfaces on the rear housing 22 of the speaker box housing 20. Thus, the light ray exited through the outer surfaces 144 and 146 of the light diffuser body 132 can enter the rear housing 22 of the speaker box housing 20. According to one or more embodiments of the present disclosure, the rear housing 22 of the speaker box housing 20 is made of a light-transmissive material or a transparent material so that light exiting from the outer surface 144 and the outer surface 146 of the light diffuser 130 and entering the rear housing 22 can be transmitted along the rear housing 22, so that the entire rear housing 22 of the speaker box housing 20 is illuminated, providing an enhanced lighting effect. According to one or more embodiments of the present disclosure, the inner surface of the rear housing 22 of the speaker box housing 20 is textured or rough to enhance the lighting effect of the speaker box device 10. According to one or more embodiments of the present disclosure, the inner surface 142 of the light diffuser 130 is inclined to enable more light to be guided to the rear housing 22 of the speaker box housing 20. According to one or more embodiments of the present disclosure, the support ridge 170 and/or the back cover 190 of the lighting assembly 100 are opaque such that light emitted by the LED elements 120 of the LED panel 110 of the lighting assembly 100 does not exit from the rear side (the support ridge 170 and the back cover 190) of the lighting assembly 100, but only from the outer surfaces 144 and 146 of the light diffuser body 132. Such a configuration further enhances the lighting effect of the speaker box device 10. According to one or more embodiments of the present disclosure, the intensity and color of the light emitted by the LED elements 120 of the LED panel 110 of the lighting assembly 100 vary with music played by the speaker box device 10. This further enhances the lighting effect of the speaker box device 10 and improves the user experience.

[0046] In the lighting assembly 100, the elongated LED panel 110 is provided with a plurality of LED elements 120 arranged along the length direction or the longitudinal direction thereof. The reflector 150 also of an elongated shape is provided with a plurality of reflective structures 160 arranged along the length direction or the longitudinal direction thereof. The light emitted by the LED elements 120 is uniformly distributed in the longitudinal direction of the lighting assembly 100 through reflection by the reflective structures 160 on the reflector 150. The lighting assembly 100 also includes a light diffuser 130, the light diffuser 130 being arranged to laterally surround the space between the LED panel 110 and the reflector 150. The light emitted from the LED elements 120 is reflected by the reflector 150, enters the light diffuser 130 from the inner surface 142 of the light diffuser 130, and exits from the outer surfaces 144 and 146 thereof. In one or more embodiments, the light diffuser 130 may be made of a translucent material such that the light emitted by the LED elements 120 is further uniformly distributed in the longitudinal direction of the lighting assembly 100. Further, the light exited from the outer surfaces 144 and 146 of the light diffuser 130 enters the rear housing 22 via respective surfaces on the rear housing 22 of the speaker box housing 20 optically coupled to the outer surfaces 144 and 146 (e.g., the two are closely adjacent and opposite to each other). The rear housing 22 may be made of a transparent or light-transmissive material such that light entering the rear housing 22 can be transmitted along the rear housing 22 to achieve a lighting effect on the whole rear housing 22. Therefore, the lighting assembly 100 of the present disclosure has a simple structure, low cost, and small footprint, and can achieve a lighting effect on the whole rear housing 22 at the same time, thereby improving user experience.

[0047] In the illustrated embodiment, the lighting assembly 100 includes an LED panel 110, a light diffuser 130, a reflector 150, a support ridge 170, and a back cover 190. The LED panel 110, the light diffuser 130, the reflector 150 and the support ridge 170 are provided with corresponding holes 114, 134, 154 and 174. The fasteners extend through these holes and are fastened to respective threaded holes 44 on the speaker box housing 20 to fasten the lighting assembly 100 to the speaker box housing 20. However, the present disclosure is not limit thereto. In one or more further embodiments according to the present disclosure, the lighting assembly 100 may employ other light sources than the LED elements. In the illustrated embodiment, the support ridge 170 provides the function of supporting and the back cover is primarily aesthetic. In one or more embodiments according to the present disclosure, the lighting assembly 100 may not include the support ridge and/or the back cover. In one or more further embodiments according to the present disclosure, the lighting assembly 100 may not include a separate support ridge and/or back cover, that is, the support ridge and/or back cover of the lighting assembly 100 may be formed integrally with other components, such as the reflector 150. In one or more other embodiments according to the present disclosure, the lighting assembly 100 may be fixed to the speaker box housing 20 via any suitable fastening structure, without using the fastening structure of fastener (e.g., a screw) and hole. In the embodiment shown in the figures, the lighting assembly 100 is used for a speaker box device. However, the present disclosure is not limit thereto. In one or more further embodiments according to the present disclosure, the lighting assembly 100 may be use for other electronic devices, provided that the housing of the electronic device also includes a transparent or light-transmissive material portion and the transparent or light-transmissive material portion thereof is optically coupled to the light diffuser of the lighting assembly 100.
