[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be fully described below with reference to the accompanying drawings in the embodiments of this invention, through specific implementation methods. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort fall within the protection scope of this invention.
[0037] Figure 1 A schematic diagram of the structure of an inner lampshade provided in the prior art. Figure 2 for Figure 1 A magnified diagram of region A in the middle, for reference. Figure 1 and Figure 2 As shown, in the prior art, the inner lampshade 10' includes a light-transmitting area 100', and the light-transmitting area 100' includes a light-incident surface 110' and a light-exiting surface 120' arranged opposite to each other. A light-transmitting structure 130' exists between the light-incident surface 110' and the light-exiting surface 120' to ensure that the light emitted by the lamp source 20' passes through the inner lampshade 10'. However, in the prior art, to achieve a better appearance for the inner lampshade 10', a two-color injection molding process is generally used during its fabrication to achieve a two-color appearance. However, to ensure the injection molding strength and processability of the inner lampshade 10', a sealing rib 140' with a "step" structure is present at the light-transmitting area 100'. However, due to the presence of the sealing rib 140', when the light emitted by the lamp source 20' passes through the sealing rib 140' and other areas of the light-transmitting area 100', the light is deflected, resulting in localized overly bright light. (Refer to...) Figure 2 The light rays a1, a2, and a3 in the lamp affect the overall light output effect of the inner lampshade 10'.
[0038] To address the aforementioned technical problems, embodiments of the present invention provide an inner lampshade. This inner lampshade includes a light-transmitting area, comprising a light-incident surface, a light-exiting surface, and at least one light-transmitting structure disposed between them. The light-incident surface and the light-exiting surface are planar or smooth curved surfaces. Incident light rays sequentially pass through the light-incident surface and the light-exiting surface to form outgoing light rays, with the angle between any two outgoing light rays being less than a preset angle. Using the inner lampshade provided by this embodiment, the light-incident surface and the light-exiting surface are planar or smooth curved surfaces, effectively ensuring parallel light emission, avoiding excessively bright local light, ensuring good uniformity of light emitted through the inner lampshade, and improving the luminous effect of the light rays passing through the inner lampshade.
[0039] The above is the core idea of this invention. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0040] Figure 3 This is a schematic diagram of the structure of an inner lampshade provided in an embodiment of the present invention. Figure 4 for Figure 3 Enlarged diagram of region B in the middle. Figure 5 This is a schematic diagram of the structure of an inner lampshade provided in an embodiment of the present invention. Figure 6 for Figure 5 A magnified diagram of region C in the middle, for reference. Figures 3 to 6 As shown, the inner lampshade 10 provided in this embodiment of the invention includes a light-transmitting area 100. The light-transmitting area 100 includes a light-incident surface 110, a light-exiting surface 120, and at least one light-transmitting structure 130 disposed between the light-incident surface 110 and the light-exiting surface 120. The light-incident surface 110 and the light-exiting surface 120 include a plane or a smooth curved surface. The incident light b passes through the light-incident surface 110 and the light-exiting surface 120 in sequence to form an outgoing light c. The included angle between any two outgoing light cs is less than a preset angle.
[0041] The inner lampshade 10 includes a light-transmitting area 100, which is used to guide the light emitted by the lamp source 20 inside the inner lampshade 10 to achieve the effect of emitting light. For example, the lamp source 20 can be a light-emitting element or a light-guiding element; this embodiment of the invention does not specifically limit this. Further, the light-transmitting area 100 includes a light-incident surface 110 and a light-exiting surface 120. The light-incident surface 110 receives the light emitted by the lamp source 20, and the light-exiting surface 120 emits the light received by the inner lampshade 10, ensuring that the lamp source 20 achieves the illumination and other light-emitting effects. (Reference) Figure 3 and Figure 5 As shown, the light source 20 is disposed inside the light incident surface 110 of the inner lampshade 10, that is, the light source 20 is disposed inside the space enclosed by the inner lampshade 10 and the inner lampshade placement area 30. The inner lampshade placement area 30 is only used to determine the positional relationship between the inner lampshade 10 and the light source 20; this embodiment of the invention does not provide a specific description of this. Simultaneously, at least one light-transmitting structure 130 is located between the light incident surface 110 and the light exit surface 120, as shown in the reference... Figure 3 and Figure 4 As shown, taking the light incident surface 110 and the light exit surface 120 as an example, which includes two types of light-transmitting structures 130, refer to... Figure 5 and Figure 6As shown, taking a light-transmitting structure 130 between the light incident surface 110 and the light exit surface 120 as an example, the embodiments of the present invention do not impose specific limitations on this.
[0042] Further reference Figures 3 to 6 As shown, the light incident surface 110 and the light exit surface 120 include planar surfaces or smooth curved surfaces. The figure uses a planar light incident surface 110 and light exit surface 120 as an example. The incident light ray b emitted from the lamp source 20 passes through the planar light incident surface 110 and is then transmitted through the light-transmitting structure 130 to the planar or smooth curved light exit surface 120, forming the exit light ray c. Since both the light incident surface 110 and the light exit surface 120 are planar, when the incident light ray b enters the inner lampshade 10 at a balanced and parallel angle, the output exit light ray c also exits from the inner lampshade 10 at a balanced and parallel angle. That is, the angle between the two exit light rays c is controllable and less than a preset angle. When the light incident surface 110 and the light exit surface 120 are smooth curved surfaces, the exit light ray c formed through the light exit surface 120 also exits at a nearly parallel angle, ensuring that the angle between the two exit light rays c is less than a preset angle. By adjusting the angle between the two emitted light rays c to be less than a preset angle, it is ensured that each emitted light ray c is emitted almost uniformly, thereby avoiding excessively bright local light and ensuring good uniformity of the light emitted after passing through the inner lampshade 10. Compared with the prior art where the light incident surface 110 is not planar or not smooth curved, it cannot be guaranteed that the angle between all emitted light rays c is less than the preset angle. That is, the angle between two emitted light rays c at different positions may be different. In other words, the embodiment of the present invention provides that the angle between any two emitted light rays c of the inner lampshade 10 is less than the preset angle.
[0043] For example, refer to Figure 4 and Figure 6 As shown, the example is an incident ray b that is evenly and parallelly incident on the ray incident surface 110. Further examples are given using any three incident rays b1, b2, and b3. These three incident rays b1, b2, and b3 sequentially pass through the ray incident surface 110 and the ray exit surface 120 to form outgoing rays c1, c2, and c3. The outgoing rays c1, c2, and c3 maintain a parallel or nearly parallel relationship; that is, the angle between two outgoing rays c is less than a preset angle.
[0044] In summary, the inner lampshade provided by the embodiments of the present invention has a light incident surface and a light exit surface that are planar or smooth curved surfaces, so that the angle between the outgoing light rays is less than a preset angle, that is, the light rays are emitted in parallel or nearly parallel, ensuring good uniformity of the light emitted after passing through the inner lampshade and improving the luminous effect of the light rays passing through the inner lampshade.
[0045] Continue to refer to Figure 3 and Figure 4 As shown, the light-transmitting structure 130 includes a first light-transmitting structure 131 and a second light-transmitting structure 132; the first light-transmitting structure 131 includes a first light-transmitting portion 131A and a second light-transmitting portion 131B connected to each other; the first light-transmitting portion 131A is disposed in the area defined by the light incident surface 110 and the light exit surface 120; the second light-transmitting portion 131B and the second light-transmitting structure 132 are sequentially disposed in the area defined by the light incident surface 110 and the light exit surface 120.
[0046] The light-transmitting structure 130 includes a first light-transmitting structure 131 and a second light-transmitting structure 132. By setting multiple light-transmitting structures 130 between the light incident surface 110 and the light exit surface 120 of the inner lamp cover 10, the light transmission effect of the inner lamp cover 10 can be enriched, thereby achieving a richer display of the light emitted by the light source 20.
[0047] Specifically, the first light-transmitting structure 131 includes a first light-transmitting portion 131A and a second light-transmitting portion 131B that are interconnected, as shown in the reference. Figure 4 As shown, the first light-transmitting portion 131A is directly located within the area defined by the light incident surface 110 and the light exit surface 120, while the second light-transmitting portion 131B and the second light-transmitting structure 132 are sequentially arranged within the area defined by the light incident surface 110 and the light exit surface 120. In other words, the first light-transmitting structure 131 surrounds the second light-transmitting structure 132 within the area defined by the light incident surface 110 and the light exit surface 120 through the second light-transmitting portion 131B. That is, the overall thickness of the first light-transmitting structure 131 is greater than that of the second light-transmitting structure 132, thereby ensuring the planar or smooth curved surface design of the light incident surface 110 and the light exit surface 120. This results in the angle between the emitted light rays c being less than a preset angle, achieving parallel light emission and ensuring good uniformity of the light emitted through the inner lampshade, thus improving the luminous effect of the light passing through the inner lampshade.
[0048] Furthermore, the first light-transmitting structure 131 and the second light-transmitting structure 132 have different light-transmitting colors.
[0049] Specifically, the colors of the light-transmitting structure 130 can be enriched to improve the light emission effect of the light source 20 through the inner lampshade 10. A two-color injection molding process is used to achieve two colors of the light-transmitting structure 130 in the inner lampshade 10. This involves adjusting the position of the "stepped" structure to meet injection molding stability and processability requirements. While ensuring that the light incident surface 110 and the light exit surface 120 are flat or smoothly curved surfaces, this ensures that the emitted light rays c are parallel or nearly parallel, resulting in good uniformity of the light emitted from the inner lampshade 10 and improving the luminous effect of the light source passing through the inner lampshade 10.
[0050] Further reference Figure 3 and Figure 4 As shown, the inner lampshade 10 also includes a first edge sealing step 140; the first edge sealing step 140 is located at at least one end of the light incident surface 110.
[0051] For details, please refer to Figure 3 and Figure 4 As shown, when the light emitting surface 120 and the light emitting surface 110 and the light emitting surface 120 include two types of light-transmitting structures 130, the present invention does not specifically limit the number of types of light-transmitting structures 130, and only two types are used as examples for explanation.
[0052] Specifically, when there are two types of light-transmitting structures 130, i.e., different colors of the different types of light-transmitting structures 130, a two-color injection molding process is used when preparing the inner lampshade 10. To ensure the structural stability of the inner lampshade 10 prepared by the two-color injection molding process, a first edge-sealing step 140 is present, i.e., the first edge-sealing step 140 is a sealing rib used to ensure the injection molding strength and processability of the prepared inner lampshade 10, that is, to ensure the structural stability and processability of the inner lampshade 10. When the first edge-sealing step 140 must exist, this embodiment of the invention adjusts the setting of the light-transmitting structure 130 so that the first edge-sealing step 140 is located at at least one end of the light incident surface 110, i.e., to minimize the interference of the first edge-sealing step 140 on the light transmission path through the inner lampshade 10. Thus, while ensuring the structural stability and good processability of the inner lampshade 10, it can also ensure the transmission of light emitted by the inner lampshade 10 to the lamp source 20, ensuring the overall luminous effect.
[0053] Further reference Figure 5 and Figure 6 As shown, the inner lampshade 10 also includes a second edge sealing step 150; the inner lampshade 10 also includes a non-transparent area 200; along the first direction X, the non-transparent area 200 covers the second edge sealing step 150; the first direction X is parallel to the direction from the light incident surface 110 to the light exit surface 120.
[0054] The inner lampshade 10 also includes a non-transparent area 200. Based on the presence of a transparent area 100 and a non-transparent area 200, the inner lampshade 10 can be fabricated using a two-color injection molding process. To ensure the structural stability and manufacturability of the fabricated inner lampshade 10, and to maintain its high plasticity, a second edge-sealing step 150 is present at the boundary of the transparent area 100 of the inner lampshade 10. Specifically, the second edge-sealing step 150 is located at at least one end near the light incident surface 110. (Reference) Figure 5 and Figure 6 As shown, the second edge sealing step 150 is located at both ends near the light incident surface 110.
[0055] Further reference Figure 5 and Figure 6 As shown, along the first direction X, the non-transparent area 200 covers the second sealing step 150. That is, by setting the non-transparent area 200, the second sealing step 150, which will affect the light output effect of the emitted light c of the inner lamp cover 10, can be blocked. This ensures the structural stability of the inner lamp cover 10, while also ensuring the transmission of light emitted by the inner lamp cover 10 to the light source 20, thus ensuring the overall light emission effect.
[0056] Further reference Figure 5 and Figure 6 As shown, the non-transparent area 200 includes a first non-transparent area 210 and a second non-transparent area 220 connected to each other; the first non-transparent area 210 includes a first non-transparent surface 210A and a second non-transparent surface 210B arranged opposite to each other, and the second non-transparent area 220 includes a third non-transparent surface 220A and a fourth non-transparent surface 220B arranged opposite to each other; the surface where the first non-transparent surface 210A is located is the same as the surface where the light incident surface 110 is located, and the third non-transparent surface 220A is located on the side of the light incident surface 110 closer to the light exit surface 120; the surface where the second non-transparent surface 210B is located, the surface where the fourth non-transparent surface 220B is located, and the surface where the light exit surface 120 is located are the same.
[0057] The non-transparent area 200 includes a first non-transparent area 210 and a second non-transparent area 220. By adjusting the positions of the first non-transparent area 210 and the second non-transparent area 220, the non-transparent area 200 covers the second sealing step 150. Specifically, the first non-transparent area 210 includes a first non-transparent surface 210A and a second non-transparent surface 210B. The surface containing the first non-transparent surface 210A is the same as the surface containing the light incident surface 110, and the surface containing the second non-transparent surface 210B is the same as the surface containing the light emitting surface 120. This ensures the regularity of the overall structure of the inner lampshade 10 and facilitates the manufacturing of the inner lampshade 10. Furthermore, the second opaque area 220 includes a third opaque surface 220A and a fourth opaque surface 220B. The third opaque surface 220A is located on the side of the light incident surface 110 that is closer to the light exit surface 120. The surface where the fourth opaque surface 220B is located is the same as the surface where the light exit surface 120 is located. That is, the third opaque surface 220A is closer to the light exit surface 120 than the first opaque surface 210A and the surface where the light incident surface 110 is located. Based on this design, the second opaque area 220 blocks the second edge sealing step 150 along the first direction X, preventing the incident light b from passing through the second edge sealing step 150 to form the outgoing light c. This ensures that any light emitted by the inner lampshade 10 is in a balanced parallel or nearly parallel relationship, thus ensuring the transmission of light emitted by the inner lampshade 10 to the light source 20 and ensuring the overall luminous effect.
[0058] Furthermore, the non-transparent area 200 includes a non-transparent structure.
[0059] The non-transparent area 200 includes a non-transparent structure to prevent light from the light source 20 from escaping from the inner lampshade 10. This can be achieved by using a structure that blocks light from the inner lampshade 10, such as the second edge sealing step 150, to ensure the light transmission effect of the inner lampshade 10. Furthermore, the non-transparent structure is made of opaque material; for example, it can be a black light-blocking structure or a light-absorbing structure. This embodiment of the invention does not impose specific limitations on this.
[0060] Furthermore, the second sealing step 150 is integrally set with the light incident surface 110.
[0061] For details, please refer to Figure 5 and Figure 6 As shown, the second edge sealing step 150 can be integrally set with the light-transmitting structure 130 that forms the light incident surface 110, which can reduce the process cost of the inner lamp cover 10 during manufacturing.
[0062] Figure 7 This is a schematic diagram of the structure of an inner lampshade provided in an embodiment of the present invention. Figure 8 for Figure 7 A magnified diagram of region D in the middle, for reference. Figure 7 and Figure 8 As shown, the inner lampshade 10 also includes a secondary light-transmitting area 300. The secondary light-transmitting area 300 includes a secondary light-incident surface 310, a secondary light-outceasing surface 320, and a third light-transmitting structure 160 disposed between the secondary light-incident surface 310 and the secondary light-outceasing surface 320. The secondary light-incident surface 310 and the secondary light-outceasing surface 320 include planar or smooth curved surfaces. The surface where the secondary light-incident surface 310 is located is the same as the surface where the light-incident surface 110 is located, and the surface where the secondary light-outceasing surface 320 is located is the same as the surface where the light-outceasing surface 120 is located.
[0063] The inner lampshade 10 may also include a secondary light-transmitting area 300, for reference. Figure 7 and Figure 8 As shown, the secondary light-transmitting area 300 includes a secondary light-incident surface 310, a secondary light-outceasing surface 320, and a third light-transmitting structure 160. Both the secondary light-incident surface 310 and the light-incident surface 110 can transmit the light emitted from the lamp source 20. Both the third light-transmitting structure 160 and the light-transmitting structure 130 allow light to pass through the inner lampshade 10, ensuring that the light can exit through the secondary light-outceasing surface 320 and the light-outceasing surface 120. Furthermore, the third light-transmitting structure 160 and the light-transmitting structure 130 can be of different colors, thus enriching the light emission effect of the inner lampshade 10 and enhancing its functionality.
[0064] Furthermore, the surface where the secondary light incident surface 310 is located is the same as the surface where the light incident surface 110 is located, and the surface where the secondary light exiting surface 320 is located is the same as the surface where the light exiting surface 120 is located. This ensures the regularity of the overall structure of the inner lampshade 10, and while maintaining aesthetics, it can also reduce the manufacturing process of the inner lampshade 10, thereby reducing costs.
