At this time, the light-emitting device can illuminate or highlight specific parts at night, improving the recognition and attractiveness of the product.

[0003] In order to prevent external water, oxygen or dust from entering the interior of the light-emitting device, the partially light-transmitting outer shell needs to be designed as a sealed structure. In order to enable the light emitted by the internal LED light source to be emitted from a specific part while the partially light-transmitting outer shell can play a sealing role, the prior art uses a combination of an upper cover, a lower cover and a light-emitting ring to form a partially light-transmitting outer shell. The light-emitting ring is clamped by the upper cover and the lower cover, and serves as a part of the side wall of the partially light-transmitting outer shell. At this time, the upper cover and the lower cover are not light-transmitting, and only the light-emitting ring is partially light-transmitting, thereby allowing light to be emitted from the light-emitting ring to achieve the effect of partial light transmission.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0031] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] Please refer to Figure 1 and Figure 2 , the horizontal direction and the thickness direction are Figure 2 The X direction in the height direction is Figure 2 The Z direction in .

[0033] The embodiment of the present application provides a partially light-transmitting housing 10, which includes a main body 100 and a light-shielding layer 200, and the outer surface of the main body 100 includes a light-shielding area (not marked in the figure) and a light-transmitting area 110;

[0034] The light shielding layer 200 covers the light shielding area to shield the light 300 , and the light transparent area 110 is used to allow the light 300 to penetrate.

[0035] When the LED light source 400 is placed in the partially light-transmitting housing 10, Figure 2As shown, the light source cannot be emitted from the portion of the partially light-transmitting housing 10 having the light-shielding layer 200, so it will be transferred to the light-transmitting area 110 in the case of multiple refractions, and then emitted from the light-transmitting area 110. The present application divides the main body 100 into a light-shielding area and a light-transmitting area 110, and covers the light-shielding area with the light-shielding layer 200, so that only the light-transmitting area 110 of the main body 100 can allow the light 300 to pass through, thereby achieving the partial light-transmitting effect of the partially light-transmitting housing 10 without the need for additional devices, thereby successfully reducing the production cost and assembly efficiency.

[0036] It is understood that the light shielding layer 200 can be integrally formed with the main body 100 or connected to the main body 100. The light shielding layer 200 can have multiple layers, thereby improving the light shielding effectiveness of the partially light-transmitting housing 10. Figure 2 As shown, the main body 100 of the partially light-transmitting shell 10 has a certain thickness, which can be light-transmitting or semi-transmitting, so that the light 300 can propagate in the partially light-transmitting shell 10. For example, when the material of the partially light-transmitting shell 10 is transparent plastic, the area where the light-shielding layer 200 is located is defined as the light-shielding area. The operator can set the light-transmitting area 110 at any place of the partially light-transmitting shell 10 according to actual needs. In some cases, for example, only the upper half of the partially light-transmitting shell 10 is required to be light-transmitting. At this time, the lower half and the upper half of the main body 100 can be separated, and the lower half is made of different light materials, while the upper half is made of semi-transmitting and light-transmitting materials. At this time, the light transmission of the lower half can be better avoided, and the assembly cost of the light-shielding layer 200 of the lower half is omitted.

[0037] For further information, please refer to Figures 1 to 4 The main body 100 includes an upper cover 20 and a lower cover 30, and the upper cover 20 is detachably connected to the lower cover 30;

[0038] The light-transmitting area 110 is located at the connection between the upper cover 20 and the lower cover 30 .

[0039] In the application scenario of the partially light-transmitting housing 10, the main body 100 usually includes an upper cover 20 and a lower cover 30, and the upper cover 20 is detachably connected to the lower cover 30, thereby realizing the function of quickly installing internal devices (such as LED light sources 400). Therefore, based on the requirements of CNC and other processing techniques, in order to reduce the processing cost of the partially light-transmitting housing 10, a light-transmitting area 110 is usually set at the connection between the upper cover 20 and the lower cover 30. Therefore, during the production process, the light-shielding layer 200 is first laid on the surface of the partially light-transmitting housing 10 (including the light-transmitting area 110 and the light-shielding area), and then a part of the light-shielding layer 200 is cut off by CNC and other processes, so that the light-transmitting area 110 is exposed, thereby allowing the light 300 to be emitted from the light-transmitting area 110.

[0040] It is understandable that the light-transmitting area 110 may be located in the upper cover 20 and / or the lower cover 30 , and the specific location is set according to actual process requirements.

[0041] For further information, please refer to Figures 2 to 4 A side wall (not marked in the figure) of one of the upper cover 20 and the lower cover 30 is provided with an annular groove 120, and a side wall of the other is provided with an annular protrusion 111; the annular protrusion 111 is located in the annular groove 120 and is used to clamp the upper cover 20 and the lower cover 30.

[0042] In the actual production process, the upper cover 20 and the lower cover 30 can be connected by threaded connection, magnetic attraction, etc., but the threaded connection of the above method will make the assembly of the partially light-transmitting shell 10 complicated, which is not conducive to the subsequent maintenance of the internal components. The magnetic attraction connection method may cause the upper cover 20 and the lower cover 30 to be easily separated and slipped. Therefore, the present application adopts the connection method of the annular protrusion 111 and the annular groove 120 to achieve the connection between the upper cover 20 and the lower cover 30. When the protrusion of the annular groove 120 is located in the annular groove 120, the upper cover 20 is wrapped by the annular groove 120 in the horizontal direction and cannot move, thereby achieving the connection between the upper cover 20 and the lower cover 30.

[0043] Furthermore, the annular protrusion 111 and the annular groove 120 are interference fit. When the annular protrusion 111 and the annular groove 120 are interference fit, the upper cover 20 and the lower cover 30 can be tightly combined due to the existence of friction, thereby preventing the upper cover 20 from falling off in the vertical direction, and further improving the sealing performance of the partially transparent housing 10, preventing the internal components from being corroded by substances such as water and oxygen. It is understandable that at this time, the annular groove 120 and the part where the annular protrusion 111 is located can have a certain elasticity, and provide a certain pre-tightening force through elastic deformation, thereby preventing the upper cover 20 and the lower cover 30 from deformation and falling off due to long-term interference fit.

[0044] For further information, please refer to Figures 2 to 4 , the light-transmitting area 110 is located between the annular protrusion 111 and the light-shielding area. In the actual processing process, the annular groove 120 and the annular protrusion 111 are usually made by cutting or lathe processing. In order to facilitate processing and improve the production efficiency of the partially light-transmitting shell 10, the light-transmitting area 110 can be set at the connection between the annular protrusion 111 and the light-shielding area. At this time, after the light-shielding layer 200 is laid on the light-transmitting area 110 and the light-shielding area, the light-shielding layer 200 and the annular protrusion 111 can be cut and formed by starting the cutting process once, thereby improving the production efficiency.

[0045] It is understandable that the prior art emits light through a light-emitting ring, so when processing the light-shielding layer 200, the light-shielding layer 200 is usually flush with the lower surface of the upper cover 20 (the side close to the lower cover 30). In this case, because the light-shielding layer 200 is usually prepared by an IML (in-mold insert injection molding) molding process, it is easy to form edge folding, discontinuity and other shapes when the positioning accuracy and injection molding pressure are difficult to control, resulting in uneven edges, affecting the aesthetics of the partially light-transmitting shell 10 and easily causing scratches to the user. In the present application, there is no need to set a light-emitting ring, which uses the light-transmitting area 110 to emit the light 300, and the processing of the light-transmitting area 110 can be achieved by CNC cutting the light-shielding layer 200. During CNC cutting, the edge of the light-shielding layer 200 is equivalent to being processed twice, and it has a flat characteristic. Therefore, the partially light-transmitting shell 10 of this embodiment has high aesthetics and is not easy to scratch the user.

[0046] For further information, please refer to Figures 2 to 4 . The thickness ratio of the light-transmitting area 110 to the annular protrusion 111 is (2-3):1. The annular protrusion 111 can actually be understood as a portion of the light-transmitting area 110 that is cut close to the annular groove 120. It serves to connect the upper cover 20 and the lower cover 30, so it needs to have a certain structural strength. The thinner the light-transmitting area 110 is, the better the light-transmitting effect is. Therefore, when designing the partially light-transmitting housing 10, the thickness ratio of the light-transmitting area 110 and the annular protrusion 111 needs to be considered. In the embodiment of the present application, the thickness ratio of the light-transmitting area 110 and the annular protrusion 111 can be any value of 2:1, 2.1:1, 2.2:1, 2.3:1, 2.4:1, 2.5:1, 2.6:1, 2.7:1, 2.8:1, 2.9:1, and 3:1, or a range formed by any two values. In this case, the partially light-transmitting outer shell 10 has good light-transmitting effect and a stable structure, and the upper cover 20 and the lower cover 30 are not easy to slip off.

[0047] For further information, please refer to Figures 2 to 4 The thickness of the light-transmitting area 110 is 2.99 mm to 3.01 mm; the thickness of the annular protrusion 111 is 1.19 mm to 1.21 mm; the thickness of the light-shielding layer 200 is 0.1 mm. The light-shielding layer 200 is a PET film; and the main body 100 is an elastic member.

[0048] In the actual production process, the thickness of the light-transmitting area 110 can be set to any value of 2.99mm, 3mm, 3.01mm or a range formed by any two values, and the thickness of the annular protrusion 111 can be set to any value of 1.19mm, 1.2mm, 1.21mm or a range formed by any two values, so that the light transmission effect and structural stability of the partially light-transmitting shell 10 meet the actual production standards. The thickness of the light-shielding layer 200 can be 0.1mm, thereby avoiding the shape change of the partially light-transmitting shell 10 due to its excessive thickness, and at the same time enabling it to meet the light-shielding requirements. The material of the PET (polyester) film enables it to be adapted to a main body of a variety of materials, thereby achieving a close connection with the main body 100.

[0049] Accordingly, please refer to Figure 1 to Figure 2 The present application also provides a light-emitting device, which includes the partially light-transmitting housing 10 of any one of the above items.

[0050] When the LED light source 400 is placed in the partially light-transmitting housing 10, Figure 2 As shown, the light source cannot be emitted from the portion of the partially light-transmitting housing 10 having the light-shielding layer 200, so it will be transferred to the light-transmitting area 110 in the case of multiple refractions, and then emitted from the light-transmitting area 110. The present application divides the main body 100 into a light-shielding area and a light-transmitting area 110, and covers the light-shielding area with the light-shielding layer 200, so that only the light-transmitting area 110 of the main body 100 can allow the light 300 to pass through, thereby achieving the partial light-transmitting effect of the partially light-transmitting housing 10 without the need for additional devices, thereby successfully reducing the production cost and assembly efficiency.

[0051] It is understandable that the light-emitting devices include but are not limited to smart phones, tablet computers, e-book readers, desk lamps, chandeliers, lamps, home decorations, control panels of industrial equipment, indicator lights and other devices.

[0052] For further information, please refer to Figure 2 The light emitting device includes an LED light source 400 , and the LED light source 400 is evenly distributed in the partially light-transmissive housing 10 .

[0053] like Figure 2 As shown, a plurality of LED light sources 400 are arranged inside the partially light-transmitting shell 10, and the LED light sources 400 are evenly distributed. At this time, the light emitted by the LED light sources 400 can be evenly transmitted through the upper cover 20 to the light-transmitting area 110 located on the upper cover 20, and pass through the light-transmitting area 110, thereby completing the local emission of the light 300.

[0054] It is understandable that a PCB board and other structures may be provided inside the partially light-transmitting shell 10, and the above-mentioned structure may support the LED light source 400, so that the LED light source 400 can be close to the upper cover 20, thereby avoiding the emission of light 300 and causing a reduction in the light 300 emitted from the partially light-transmitting area 110.
