Technical Field
[0001] This application belongs to the field of lighting equipment technology, specifically relating to a lamp and an automobile. Background Technology
[0002] In related technologies, to make the light emitted by vehicle indicator lights and other lamps diffuse in a dot matrix pattern, decorative parts are often used to decorate the lamps to achieve this diffusion. However, this method increases the manufacturing cost and assembly process of the lamps due to the need for decorative parts. In addition, the decorative parts also obstruct the light to some extent, hindering the diffusion of the vehicle's light and reducing the visible range of the vehicle's lights, leaving room for improvement. Summary of the Invention
[0003] Based on the above-mentioned technical problems, this application provides a lamp and an automobile to solve to a certain extent the technical problems of increasing the manufacturing cost and assembly process of the lamp caused by adding decorative parts to make the light emitted by the lamp diffuse in a dot matrix, and blocking the diffusion of the car light, resulting in a reduction in the visibility range of the car light.

[0006] The lighting fixture provided in this application, because the light guide is located on the light-emitting side of the light-emitting element, and multiple light guides are sequentially distributed, allows the light beam emitted by the light-emitting element to be guided by multiple light guides. Furthermore, because each light guide has multiple reflectors that reflect the light beam, and the reflected light beam is directed towards the light-emitting surface, the light beam emitted by the light-emitting element can be emitted in a point-like pattern through the light-emitting surface of the lampshade, forming a point-like light that serves as a warning and signal reminder. Since this application uses multiple reflectors to reflect the light beam to form a point-like light, there is no need to add decorative parts, thus reducing the manufacturing cost and assembly process of the lighting fixture. In addition, the absence of decorative parts obstructing the light ensures the visible range of the light, giving it significant practical value.

[0017] In some embodiments, in at least one of the light guides, the plurality of reflectors include a plurality of second reflectors, the plurality of second reflectors are arranged in rows, and at least one row of second reflectors is disposed between two adjacent rows of first reflectors, the second reflectors and the two adjacent rows of first reflectors are staggered.
[0018] In some embodiments, the light guide is provided with an inclined surface that is tilted towards the light-emitting surface, and a plurality of reflectors are disposed on the inclined surface.
[0019] In some implementations, along the first direction, the projection of the reflector onto the lampshade is a second projection; the second projections corresponding to the plurality of reflectors are arranged in a staggered manner.
[0020] In some embodiments, the second projections corresponding to the reflectors of at least two light guides are arranged in a row; or / and, in at least two light guides, the second projections corresponding to multiple reflectors on one light guide and the second projections corresponding to multiple reflectors on the other light guide are located in the same row, and the second projections located in the same row are spaced apart.
[0021] In some embodiments, the reflector is provided with a second reflective surface and a light-transmitting surface. The second reflective surface is inclinedly disposed in the emission direction of the light beam to change the propagation direction of the light beam. The light-transmitting surface is disposed in the reflection direction of the light beam to output the light beam reflected by the second reflective surface to the light-emitting surface of the lampshade through the light-transmitting surface. At least one of the second reflective surface and the light-transmitting surface is provided with texture to adjust the light emission angle of the light beam passing through the light-emitting surface.

[0057] The technical solutions in this application will now be clearly and thoroughly described with reference to the accompanying drawings. Specifically, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0058] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0059] With the rapid development of the road transportation industry, automobiles are becoming increasingly integrated into people's daily lives. As people's living standards improve, they not only pursue high standards in vehicle performance but also have higher demands for personalized and decorative experiences. Vehicle signal lights and other lighting fixtures are important functional components of automobiles, playing a crucial role in indicating direction during driving. On the one hand, they serve as warnings and signals to ensure driving safety; on the other hand, they complement the vehicle's appearance, adding a finishing touch to its design and satisfying customers' desire for personalized and customizable features.
[0060] In related technologies, when a lamp emits a beam of light, the beam is guided directly through the lamp's cover by a light guide. However, due to the thickness of the light guide, molding is difficult, time-consuming, and complex. Furthermore, the emitted beam is monotonous, lacking spatial depth and layering. Therefore, to create a matrix of light, decorative elements are often used to decorate the lamp, making the emitted light diffuse in a matrix pattern. However, this method increases manufacturing costs and assembly processes due to the added decorative elements. Additionally, the decorative elements can obstruct the light to some extent, reducing the visibility range of the vehicle's headlights. Furthermore, increasing the number of LEDs to achieve matrix lighting can lead to poor heat dissipation on the circuit boards electrically connected to the LEDs, further increasing costs.
[0061] To address the aforementioned technical issues, this application provides a lighting fixture and an automobile that uses multiple reflectors to reflect and guide the light beam, thereby changing the direction of the light beam emitted by the light source to form a dot matrix light beam with a sense of space and layering, thus improving the user experience.
[0062] Based on the above design concept, in the first aspect of this application, this application provides a lighting fixture. Figure 1A schematic diagram of the structure of a lamp 10 according to one or more embodiments of this application is shown. Figure 2 It shows Figure 1 Internal diagram, Figure 3 A schematic diagram of the beam propagation is shown. For clarity, Figure 2 Removed Figure 1 The lampshade 110 in the middle and the frame 140 in the following text are combined Figures 1-3 The lamp 10 includes a lampshade 110, a light-emitting element 120, and a light guide 130. The lampshade 110 is provided with a light-emitting surface 111, and the light-emitting element 120 is used to emit a light beam. The light guide 130 is located on the light-emitting side of the light-emitting element 120. The light guide 130 includes a light guide body 132 and a reflector 131. Along a first direction, multiple light guide bodies 132 are sequentially arranged downstream of the light-emitting element 120. Along a second direction, the light-emitting surface 111 is disposed on one side of multiple light guide bodies 132, and the second direction intersects with the first direction. Each light guide body 132 is provided with a reflector 131. Along the first and second directions, the reflectors 131 are staggered. The reflector 131 is used to receive the light beam emitted by the light-emitting element 120 and reflect it to the light-emitting surface 111 for output by the light-emitting surface 111. The second direction intersects with the first direction, and both the first and second directions are located in a first plane, which is parallel to the output light axis of the light-emitting element 120.
[0063] The lamp 10 provided in this application, because the light guide 130 is disposed on the light-emitting side of the light-emitting element 130, and the multiple light guides 132 of the light guide are sequentially distributed along the first direction, can guide the light beam emitted by the light-emitting element 120 through the multiple light guides 132. Furthermore, because each light guide 132 is provided with multiple reflectors 131, which reflect the light beam, the light beam reflected by the multiple reflectors 131 is directed towards the light-emitting surface 111. Therefore, the light beam emitted by the light-emitting element 120 can be emitted in a point shape through the light-emitting surface 111 of the lampshade 110, forming a point light that serves as a warning and signal reminder. Since this application forms a point light by reflecting the light beam through the multiple reflectors 131 inside the lampshade 110, there is no need to add decorative parts, thus reducing the manufacturing cost and assembly process of the lamp 10. In addition, since there are no decorative parts obstructing the light, the visibility range of the light is also guaranteed, making it highly practical.
[0064] Figure 4 It shows Figure 1 A front view diagram. Combined with... Figure 4 For ease of description, we now define Figure 2The directions shown are up-down, left-right, and front-back. That is, both the lampshade 110 and the light guide 130 have height, width, and length directions. The height direction is the up-down direction shown in the figure, the width direction is the left-right direction shown in the figure, and the length direction is the front-back direction shown in the figure. The light-emitting element 120 is located above the light guide 130. In some embodiments, the first direction described in this application is the up-down direction, which is the direction in which the light beam is incident on the reflector 131. The second direction is the left-right direction, which is the direction in which the light beam is reflected by the reflector 131. That is, the first and second directions are perpendicular. The third direction mentioned below is the front-back direction, which is perpendicular to the first plane containing the first and second directions. In other embodiments, the first and second directions can also be other directions, and the angle between the first and second directions can be acute or obtuse. This application does not limit this. The specific details of the lamp 10 will now be further described with reference to the accompanying drawings.
[0065] Figure 5 It shows Figure 1 A schematic diagram of the explosion. Combined with... Figure 5 In some embodiments, the lampshade 110 can be installed on the vehicle body by bolts or / and snap-fit. A receiving cavity 112 is formed within the lampshade 110. The receiving cavity 112 is a sealed cavity, and the light-emitting element 120 and the light guide element 130 are both disposed within the receiving cavity 112 of the lampshade 110 to protect the built-in light-emitting element 120 and light guide element 130. Additionally, the lampshade 110 includes at least two detachably connected individual structures 113 by snap-fit or similar means to facilitate the assembly of the light-emitting element 120 and light guide element 130 within the lampshade 110. The light-emitting surface 111 of the lampshade 110 is disposed on one of the individual structures 113. The light-emitting surface 111 is a planar structure and can be disposed on, for example... Figure 3 As shown on the left, the light-emitting surface 111 is made of a transparent material so that the light beam can pass through the light-emitting surface 111 of the lampshade 110 for output. In other embodiments, the lampshade 110 may be provided with a light-guiding surface or a light-guiding hole, and the light-emitting element 120 is disposed on the outside of the lampshade 110. The light beam emitted by the light-emitting element 120 is guided into the receiving cavity 112 of the lampshade 110 through the light-guiding surface or the light-guiding hole. In addition, the light-emitting surface 111 of the lampshade 110 may be disposed on the right side, the bottom, etc., as shown in the figure. The positions of the reflector and the light guide 130 can be adjusted accordingly, and this application does not impose any restrictions on this.
[0066] Figure 6 A schematic diagram of the light-emitting element 120 is shown. (Combined with...) Figure 6In some embodiments, the light-emitting element 120 includes a circuit board 121, a light-emitting lamp 122, and a focusing element 123. Multiple light-emitting lamps 122 are electrically connected to the other side of the circuit board 121 to connect to the vehicle control system and receive commands from the system to control the opening and closing of the light-emitting lamps 122. When the light-emitting lamps 122 are on, they emit a light beam. The focusing element 123 is disposed in the emission path of the light beam from the light-emitting lamp 122 to collimate the light beam emitted by the lamp 122.
[0067] Figure 7 A schematic diagram of the concentrator 123 is shown. (Combined with...) Figure 6 as well as Figure 7 In a specific implementation, the circuit board 121 is arranged vertically, and multiple light-emitting lamps 122 are connected to one side of its horizontal direction. The light-emitting lamps 122 can be LED lamps. LED lamps have the advantages of energy saving, high efficiency, long service life, and miniaturization. Multiple light-emitting lamps 122 can be arranged in a row along a third direction. The focusing element 123 has multiple light-guiding grooves 1231 on the side facing the light-emitting lamps 122 (the horizontal side of the focusing element 123). The light-guiding grooves 1231 and the light-emitting lamps 122 are arranged one-to-one. The light beam emitted by the light-emitting lamps 122 is introduced into the focusing element 123 through the corresponding light-guiding grooves 1231, and output after being collimated by the focusing element 123. The focusing element 123 can be configured as the output part of the light-emitting element 120.
[0068] Combination Figure 3 In some embodiments, one light-emitting lamp 122 corresponds to at least two light guides 132. The light beam emitted by the light-emitting lamp 122 is reflected by reflectors 131 on the corresponding at least two light guides 132 to the light-emitting surface 111, and then output from the light-emitting surface 111. This arrangement allows the light beam emitted by one light-emitting lamp 122 to be reflected by at least two reflectors 132, thereby reducing the number of light-emitting lamps 122, lowering costs, and improving the heat dissipation of the circuit board 121. For example, the light beam emitted by a light-emitting element 122, after being collimated by a focusing element 123, is reflected by the reflectors 131 on the third and fourth light guides 132, and then output from the light-emitting surface 111.
[0069] Combination Figure 4 , Figure 6 as well as Figure 7In some embodiments, the focusing element 123 is provided with a first reflective surface 1232 to change the direction of the light beam emitted by the light-emitting lamp 122, so that the light beam emitted by the light-emitting lamp 122 is directed toward multiple light guides 130. For example, as shown in the figure, the circuit board 121, the light-emitting lamp 122, and the focusing element 123 are arranged sequentially in the horizontal direction. The light beam emitted by the light-emitting lamp 122 is emitted in a horizontal rightward direction. The thickness of the focusing element 123 can be between 0.5mm and 8mm, for example, between 1.5mm and 3.5mm. The first reflective surface 1232 of the focusing element 123 has a 45° tilt angle, so that the light beam emitted by the light-emitting lamp 122 is reflected and emitted vertically downward. In a specific implementation, the first reflective surface 1232 is provided on the side of the focusing element 123 facing away from the light-emitting lamp 122 (the other side of the focusing element 123 in the horizontal direction).
[0070] In some other embodiments, the focusing element 123 may only guide the light beam emitted by the collimating lamp source, that is, the focusing element 123 does not have a first reflective surface 1232. For example, multiple light-emitting lamps 122 are located above the focusing element 123, and the light beams emitted by the light-emitting lamps 122 are emitted vertically downwards. After being collimated by the focusing element 123, they are output in the direction of the guiding element 130.
[0071] Combination Figure 5 In some embodiments, the luminaire 10 further includes a frame 140, which is assembled inside the lampshade 110, and the light-concentrating element 123 and the light guide element 130 are both vertically stacked and assembled inside the frame 140.
[0072] Figure 8 An assembly diagram of the frame 140 and the focusing element 123 is shown. Figure 9 A structural schematic diagram of frame 140 is shown. (Combined with...) Figure 8 as well as Figure 9 The frame 140 extends vertically, and a mounting groove 141 is formed inside the frame 140. The bottom of the mounting groove 141 faces the circuit board 121. The circuit board 121 can be connected to the bottom of the mounting groove 141 by screws or other connectors. A mounting opening 143 is provided at the top of the bottom of the mounting groove 141. The light-concentrating element 123 is fitted into the mounting opening 143 so that at least a part of the light-concentrating element 123 is located in the mounting groove 141. In addition, the shape of the top of the frame 140 is consistent with the shape of the top of the light-concentrating element 123, which can further reduce the size of the frame 140, and correspondingly reduce the size of the lampshade 110, reducing the space required for mounting the lampshade 110.
[0073] It should be noted that "at least part of the focusing element 123 is located in the mounting groove 141" means that the entire focusing element 123 is located in the mounting groove 141, or that part of the focusing element 123 is located in the mounting groove 141. It is only necessary to ensure that the light beam reflected by the focusing element 123 propagates and is emitted within the mounting groove 141.
[0074] Figure 10 An assembly diagram of the frame 140 and the light guide 130 is shown, in conjunction with... Figure 9 as well as Figure 10 The opening side of the mounting groove 141 faces away from the circuit board 121, that is, the opening side of the mounting groove 141 faces the horizontal right side shown in the figure. The opening side of the mounting groove 141 faces the light-emitting surface 111 of the lampshade 110. The light guide 130 includes a plurality of light guides 132, which are arranged vertically in the mounting groove 141.
[0075] Figure 11 It shows Figure 9 Front view diagram, Figure 12 It shows Figure 9 Another structural diagram from the perspective of Figure 13 A schematic diagram of the light guide 132 is shown. (Combined with...) Figures 9-13 In specific implementation, the bottom of the mounting groove 141 is provided with a positioning groove 144 and a mounting hole 145. Multiple positioning grooves 144 are provided, and the positioning grooves 144 and the light guides 132 are provided one-to-one. Each positioning groove 144 has a mounting hole 145 on both sides (both sides in the front-back direction shown in the figure). Both sides of the frame 140 in the length direction (both sides in the front-back direction shown in the figure) are provided with connecting plates 150. The connecting plates 150 extend towards the circuit board 121. Two connecting plates 150 and one mounting hole 145 are provided one-to-one. The two connecting plates 150 are positioned opposite each other on both sides of the corresponding mounting hole 145 so that the two connecting plates 150 form a mounting channel connected to the mounting hole 145. At least one of the inner walls of the two connecting plates 150 is provided with a snap-fit protrusion 151. The light guide 132 is provided with a positioning part 133. The positioning part 133 of the light guide 132 can be arranged in the horizontal direction and inserted into the corresponding positioning groove 144 so that the light guide 132 is positioned in the frame 140. In addition, both sides of the length direction of the light guide 132 (both sides of the front and back direction in the figure) are provided with insertion parts 134. The insertion parts 134, mounting holes 145 and mounting channels are provided one-to-one. The insertion parts 134 pass through the corresponding mounting holes 145 and are inserted into the corresponding mounting channels. The insertion parts 134 abut against the insertion parts 134 by snap-fit protrusions 151, thereby making the light guide 132 detachably fixedly assembled in the frame 140.
[0076] It should be noted that, in this application, the provision of a snap-fit protrusion 151 on at least one of the opposing inner walls of the two connecting plates 150 means that a snap-fit protrusion 151 is provided on one inner wall of the opposing inner walls of the two connecting plates 150, or that a snap-fit protrusion 151 is provided on both inner walls of the opposing inner walls of the two connecting plates 150. Under the condition that a snap-fit protrusion 151 is provided on both inner walls of the opposing inner walls of the two connecting plates 150, the snap-fit protrusions 151 on the two inner walls can be arranged opposite to each other or staggered. This application does not impose any restrictions on this.
[0077] In this application, each light guide 132 is provided with multiple reflectors 131. Since there are multiple light guides 132, and the multiple light guides 132 are arranged at intervals downstream of the light-emitting element 120 along the incident direction (first direction) of the light beam towards the reflector 131, the light guide 132 with reflectors 131 has a visual sense of spatial suspension and layering, which improves the user experience. Moreover, since the light beam is guided by multiple light guides 132, the light guide 132 can be made thinner and lighter, reducing the molding difficulty and cycle of the light guide 132, simplifying the production process, and has great practical value.
[0078] Figure 14 A front view schematic diagram of the light guide 132 is shown. Combined with... Figure 13 as well as Figure 14 At least a portion of the light guide 132 is inclined on the side facing away from the light focusing element 123 (i.e., the bottom of the light guide 132). Multiple reflectors 131 are connected to the inclined portion at the bottom of the light guide 132, and each reflector 131 has a second reflective surface 1311. The light guide 132 is made of a light-transmitting material. The light beam, collimated by the light focusing element 123, passes through the light guide 132 and is reflected by the second reflective surface 1311 before being output.
[0079] Combination Figure 13 as well as Figure 14 In specific implementation, the light guide 132 and the positioning part 133 are integrally formed. The light guide 132 is inclined to the positioning part 133 so that the side of the light guide 132 facing away from the light focusing member 123 (that is, the bottom of the light guide 132) is inclined. Multiple reflectors 131 are connected to the bottom of the light guide 132.
[0080] Combination Figure 14 The second reflective surface 1311 is inclinedly disposed in the emission direction of the light beam (i.e., the first direction) to change the emission direction of the light beam. By changing the emission direction of the light beam, the light-emitting element 120 emitting the light beam and the light-emitting surface 111 of the lampshade 110 can be arranged in a staggered manner, for example... Figure 3The light-emitting element 120 and the light-emitting surface 111 of the lampshade 110 are located on opposite sides, but the light-emitting element 120 is located above the light-emitting surface 111 of the lampshade 110, so that the user cannot see the light-emitting element 120 through the light-emitting surface 111, thus hiding the light-emitting element 120 and achieving completely hidden light emission, thereby improving the visual experience.
[0081] Figure 15 It shows Figure 14 Enlarged diagram of point A, Figure 16 A partial schematic diagram shows multiple reflectors 131 arranged on a light guide 132. (Combined with...) Figure 15 as well as Figure 16 In some embodiments, the reflector 131 can be a convex ridge structure. The reflector 131 and the light guide 132 are integrally formed, and a reflective layer is coated on a portion of the outer surface of the reflector 131 to form the second reflective surface 1311. At least a portion of the side of the reflector 131 away from the light-emitting surface 111 is the second reflective surface 1311. The tilt angle of the second reflective surface 1311 can be 45°. Of course, the tilt angle of the second reflective surface 1311 can be adjusted according to the incident direction of the light beam, such as 30°, 60°, etc. This application does not limit this.
[0082] In addition, combined Figure 15 as well as Figure 16 The reflector 131 also includes a light-transmitting surface 1312, which is disposed in the reflection direction (second direction) of the light beam so that the light beam reflected by the second reflector 1311 is output to the light-emitting surface 111 of the lampshade 110 through the light-transmitting surface 1312. In addition, at least one of the second reflector 1311 and the light-transmitting surface 1312 is provided with a texture, which can be applied to at least one of the second reflector 1311 and the light-transmitting surface 1312 by coating or engraving processes to adjust the light emission angle of the light beam passing through the light-emitting surface 111 and ensure the uniformity of the light emission effect.
[0083] It should be noted that having a texture on at least one of the second reflective surface 1311 and the light-transmitting surface 1312 means that the second reflective surface 1311 has a texture, or the light-transmitting surface 1312 has a texture, or both the second reflective surface 1311 and the light-transmitting surface 1312 have textures. This application does not impose any restrictions on this.
[0084] Combination Figure 15 as well as Figure 16In some embodiments, the reflectors 131 can be arranged in a trapezoidal shape, such as an isosceles trapezoid. The upper base of the reflector 131 is connected to the bottom of the light guide 132. One waist of the reflector 131 faces away from the light-emitting surface 111 of the lampshade 110, and one waist of the reflector 131 is configured as a second reflective surface 1311. The other waist of the reflector 131 faces the light-emitting surface 111 of the lampshade 110, and the other waist of the reflector 131 is configured as a light-emitting surface 111. In other embodiments, some reflectors 131 can be connected as a single unit to form different reflection effects; or, adjusting the reflection angle, length, shape, and form of the reflectors 131 can create different floating layered three-dimensional effects, which will not be elaborated here.
[0085] Figure 17 A schematic diagram showing the arrangement of multiple reflectors 131 projected onto the luminous surface 111 is illustrated. Combined with... Figure 17 In some embodiments, along the direction of the light beam reflected by the reflector 131, the projections of multiple reflectors 131 on the light-emitting surface 111 are arranged in a dot matrix, so that the light beams reflected by multiple reflectors 131 can be emitted in a dot shape through the light-emitting surface 111 of the lampshade 110 to form dot-shaped lights that serve as warnings and signal reminders, thereby achieving large-area spatial dot matrix lighting, meeting the light intensity requirements of various signal lights, and improving the visual experience.
[0086] Combination Figure 17 In some embodiments, along the direction of light beam reflection by reflector 131, the projection of reflector 131 onto light-emitting surface 111 is a first projection P1. Multiple first projections P1 corresponding to reflectors 131 are arranged in rows, with each row having the same or nearly identical number, spacing, and length of first projections P1, so that the overall light source forms a rectangle. In other embodiments, the first projections P1 corresponding to multiple reflectors 131 can also be in other shapes such as a ring or a fan, so that the overall light source forms other shapes such as a ring or a fan. Specific arrangements can be made according to design requirements, and this application will not elaborate further.
[0087] Combination Figure 17 The first projections P1 of the two adjacent rows are staggered. This arrangement can improve the density of the lights and correspondingly increase the brightness of the lights to meet the light intensity requirements of various signal lights and improve the visual experience.
[0088] In specific implementations, the first projections P1 of the reflectors 131 on the light-emitting surface 111 of at least two light guides 132 corresponding to the light-emitting lamp 122 are arranged in a dot matrix. In some embodiments, the light beam emitted by the light-emitting lamp 122 can be reflected by the reflectors 131 on the two light guides 132, and the first projections P1 of the reflectors 131 on the two light guides 132 incident with the same light beam are arranged in a dot matrix. In other embodiments, if the light beam emitted by the light-emitting lamp 122 has a sufficient width, the light beam emitted by the light-emitting lamp 122 can be reflected by more reflectors 131 on the light guides 132, such as three, four, etc., and the first projections P1 of the more reflectors 131 on the more light guides 132 incident with the same light beam are also arranged in a dot matrix.
[0089] In some embodiments, the number of light guides 132 in this application can be [number missing]. Figure 3 The four layers shown can also be three, five, etc., and this application does not limit this. However, in the output path of the light beam, that is, along the incident direction (first direction) and the reflection direction (second direction) of the light beam, it is necessary to ensure that the reflectors 131 are staggered, that is, arranged without overlap, so as to avoid affecting the propagation of the light beam. In some other embodiments, only one light guide 132 may be provided, but the reflectors 131 of the light guide 132 need to have multiple reflectors.
[0090] Figure 18 It shows Figure 13 Schematic diagram of the structure of the light guide 132 in some embodiments, Figure 19 A schematic diagram of the light guide 132 in other embodiments is shown. (Combined with...) Figure 18 as well as Figure 19 Each light guide 132 has multiple reflectors 131 arranged in a row, and the arrangement direction of the reflectors 131 is along the setting direction of the second reflective surface 1311. Since the second reflective surface 1311 is arranged at an angle, the second projection P2 corresponding to the multiple reflectors 131 of each light guide 132 can be arranged in a row.
[0091] Combination Figure 18 as well as Figure 19 In some embodiments, along the arrangement direction of the reflectors 131, adjacent rows of reflectors 131 in each light guide 132 are staggered, thereby preventing reflectors 131 near the light-emitting surface 111 of the lampshade 110 from blocking the light beam output of reflectors 131 away from the light-emitting surface 111 of the lampshade 110. For example Figure 3 and Figure 4 All four light guides 132 shown are configured in this way. In other embodiments, only some of the light guides 132 may have reflectors 131 configured in this way. This application does not limit this.
[0092] Figure 20 It shows Figure 19 The diagram shows the interaction between the light guide 132 and the light-emitting surface 111. (Combined with...) Figure 19 as well as Figure 20 In some other embodiments, in at least one light guide 132, a plurality of reflectors 131 include a plurality of first reflectors 131a, which are arranged in a rectangular array. Multiple rows of first reflectors 131a are sequentially positioned close to the light-emitting surface 111. Specifically, in two adjacent rows of first reflectors 131a, along the incident direction of the light beam (i.e., the first direction), the row of first reflectors 131a closer to the light-emitting surface 111 protrudes beyond the first reflectors 131a of the other row. That is, in two adjacent rows of first reflectors 131a, the distance from the first reflectors 131a closer to the light-emitting surface 111 to the light-concentrating element 123 is H1, and the distance from the first reflectors 131a of the other row to the light-concentrating element 123 is H2, where H1 < H2. For example, the multi-row first reflector 131a includes a first row of reflectors 131 and a second row of reflectors 131, arranged in a rectangular array. The first row of reflectors 131 is closer to the light-emitting surface 111 of the lampshade 110 than the second row of reflectors 131. The distance H1 between each first reflector 131a in the first row of reflectors 131 and the focusing member 123 is smaller than the distance H2 between each first reflector 131a in the second row of reflectors 131 and the focusing member 123, so that the first reflectors 131a in the first row of reflectors 131 protrude from the first reflectors 131a in the second row of reflectors 131. This arrangement avoids the first row of reflectors 131, which are closer to the light-emitting surface 111, blocking the light output of the second row of reflectors 131, which are farther from the light-emitting surface 111, thus enabling more light-emitting parts and improving the light intensity.
[0093] In some embodiments, since at least a portion of the bottom of the light guide 132 is inclined, the above-mentioned setting can be achieved by adjusting the inclination angle of at least a portion of the bottom of the light guide 132. Specifically, the inclination angle of at least a portion of the bottom of the light guide 132 is 20°. Of course, it can also be set according to the specific height of the reflector 131, such as 30°, 40°, etc., and this application does not impose any limitations on this. In other embodiments, the bottom of the light guide 132 may not have an inclined surface, and the above-mentioned setting can be achieved by changing the length of the reflector 131 near the light-emitting surface 111 of the lampshade 110. This application does not impose any limitations on this.
[0094] Combination Figure 19 as well as Figure 20Furthermore, in some other embodiments, in at least one light guide 132, the plurality of reflectors 131 include a plurality of second reflectors 131b, which are arranged in rows. At least one row of second reflectors 131b is disposed between two adjacent rows of first reflectors 131a, and the second reflectors 131b and the adjacent two rows of first reflectors 131a are staggered. This arrangement can also prevent a row of reflectors 131 near the light-emitting surface 111 from blocking the light output of another row of reflectors 131 away from the light-emitting surface 111, and can realize more light-emitting parts and improve the light emission intensity. For example Figure 3 and Figure 4 The light guide 132 shown is configured in this way, located in the odd-numbered column.
[0095] It should be noted that in the various light guides 132 in this application, some of the light guides 132 have multiple rows of reflectors 131 arranged in a staggered manner, that is, adjacent rows of reflectors 131 are staggered, and two rows of reflectors 131 that are spaced apart are also staggered, so that any two rows of reflectors 131 are staggered, such as Figure 3 and Figure 4 The second and fourth light guides 132 are shown; while some other light guides 132 are provided with multiple rows of reflectors 131, which not only have the first and second rows of reflectors 131, but also have a third row of reflectors 131, which can be disposed between the first and second rows of reflectors 131. Figure 3 The first and third light guides (132 and 132) can also be disposed outside the first and second row reflectors 131. The third row reflector 131 is staggered from the first and second row reflectors 131 to avoid affecting the propagation of the light beam.
[0096] Figure 21 A schematic diagram of the projection of a reflector 131, which is provided for a certain light guide 132, onto the lampshade 110. Figure 22 A schematic diagram showing the projection of the reflectors 131, which are provided by other light guides 132, onto the lampshade 110 is shown. Combined with... Figure 21 as well as Figure 22 In some embodiments, along the incident direction of the light beam toward the reflector 131 (i.e., the first direction), the projection of the reflector 131 onto the lampshade 110 is a second projection P2; the second projections P2 corresponding to multiple reflectors 131 are staggered. This arrangement can prevent the upstream reflector 131 from blocking the propagation of the light beam toward the downstream reflector 131.
[0097] Combination Figure 21 as well as Figure 22In some embodiments, the second projections P2 corresponding to the reflectors 131 of at least two light guides 132 are arranged in a row, for example... Figure 3 The first light guide 132 and the second light guide 132 shown are... Figure 3 The third light guide 132 and the fourth light guide 132 shown in the figure.
[0098] Figure 23 A schematic diagram showing the projection of two light guides 132 onto the lampshade 110 via a reflector 131 is shown. (Combined with...) Figure 23 In other embodiments, in at least two light guides 132, the second projections P2 corresponding to the plurality of reflectors 131 disposed on one light guide 132 and the second projections P2 corresponding to the plurality of reflectors 131 disposed on the other light guide 132 are located in the same row, and the second projections P2 in the same row are spaced apart. For example Figure 3 The first light guide 132 and the third light guide 132 in the middle Figure 3 The second light guide 132 and the fourth light guide 132 in the middle. Figure 23 In the upper row of second projections P2, odd-numbered second projections P2 correspond to the second projections P2 of the reflectors 131 set by the first light guide 132, and even-numbered second projections P2 correspond to the second projections P2 of the reflectors 131 set by the second light guide 132. In the lower row of second projections P2, odd-numbered second projections P2 correspond to the second projections P2 of the reflectors 131 set by the second light guide 132, and even-numbered second projections P2 correspond to the second projections P2 of the reflectors 131 set by the second light guide 132.
[0099] It should be noted that each light guide 132 in this application may only have the structure of the light guide 132 located in the odd-numbered column, or the structure of the light guide 132 located in the even-numbered column may also have the structure of the light guide 132 located in both the odd-numbered and even-numbered columns. This application does not impose any restrictions on this.
[0100] In summary, the lamp 10 provided in this application reflects and guides the light beam through multiple reflectors 131 built into the lampshade 110 to form a dot matrix light beam with a sense of space and layering, thereby improving the user experience. In addition, it can reduce the number of light-emitting lamps 122, reduce costs, and improve the heat dissipation effect of the circuit board 121. Furthermore, by dividing the light guide 130 into multiple independent light guides 132 to guide the light beam, the light guide 132 can be made thinner and lighter, reducing the molding difficulty and cycle of the light guide 132, simplifying the production process, and has great practical value.
