Abstract
Description
Technical Field
[0001] This application relates to the field of automotive lighting technology, and more particularly to a lighting fixture. Background Technology
[0002] In the field of lighting equipment, interior small lights generally include reading lights, trunk lights, ambient lights, and side ceiling lights, which are widely used in various motor vehicles. With the development of the automotive industry, higher requirements are being placed on the performance, stability, and variety of interior small lights.
[0003] In related technologies, some decorative lights illuminate the decorative area by surrounding lights to enhance the aesthetics of the lights. However, when users view these decorative lights, their eyes are easily stimulated by the emitted light, affecting their viewing experience. Utility Model Content
[0004] This application provides a lighting fixture to improve the problem in related technologies where the user's eyes are easily stimulated by the emitted light when viewing decorative lights, affecting the user's experience.
[0005] This application provides a lamp, including: The lamp housing has a receiving cavity and a light outlet communicating with the receiving cavity, and the inner wall surface of the receiving cavity includes a reflective surface; A decorative element, disposed in the receiving cavity, the decorative element having a decorative surface visible through the light-emitting port; and, A light-emitting element is disposed in the receiving cavity. The reflective surface and the shaped surface are distributed along the light emission path of the light-emitting element. The reflective surface is used to reflect the light emitted by the light-emitting element to the shaped surface to illuminate the shaped surface.
[0006] In the vehicle headlight module of this application embodiment, the light-emitting element is hidden in the receiving cavity. The light needs to be reflected by the reflective surface before reaching the shaped surface. The light is not directly exposed to the light outlet, which reduces the possibility of direct light leakage and makes it difficult to cause glare problems, thereby reducing the stimulation to the human eye. Moreover, after the reflected light is diffused twice by the shaped surface, the visual effect is softer and more stable.
[0007] In some embodiments, the light-emitting element is obscured when viewed from the light-emitting port toward the interior of the lamp housing along the depth direction of the receiving cavity.
[0008] In the above embodiments, after the light-emitting element is blocked by the lamp housing, it is difficult to directly observe the messy structure such as the light-emitting element and circuits inside from the light outlet. The visual appearance is simpler and more unified, and it can also protect the light-emitting element to a certain extent.
[0009] In some embodiments, the light-emitting element includes a plurality of light-emitting lamps, which are distributed at circumferential intervals along the shaped element and located on the outer periphery of the shaped element; The outline of the light outlet has a first orthographic projection on the plane where the shaped surface is located, and the first orthographic projection is located within the shaped surface.
[0010] In the above embodiments, when viewed from the light outlet, only the shaped surface can be seen. There are no extra frame shadows caused by the misalignment between the light outlet edge and the shaped surface, and it is difficult for light leakage or stray light interference to occur. This makes the pattern and texture of the shaped surface the visual focus and ensures the user's visual experience.
[0011] In some embodiments, there is a gap between the shaped component and the lamp housing, at least around the periphery of the shaped component, and the gap communicates with the light outlet. When viewed from the light outlet toward the inside of the lamp housing, the light-emitting element is located in the non-visible area of the gap.
[0012] In the above embodiments, the light-emitting element is located in a non-visible area, completely eliminating the possibility of direct light from the light-emitting element entering the human eye, making it difficult for users to be stimulated by light when viewing the decorative lights, thus ensuring the user's viewing experience.
[0013] In some embodiments, the light-emitting element is located on the side of the shaped surface opposite to the light-emitting port.
[0014] In the above embodiments, the light-emitting element is further away from the light outlet, making it difficult for dust, moisture, and external forces to come into contact with it, thus improving the protection of the light-emitting element and ensuring its stability.
[0015] In some embodiments, the light outlet is circular, the outer periphery of the shaped surface is circular, and the light outlet and the shaped surface are coaxially arranged.
[0016] In the above embodiment, the light outlet and the shaped surface are coaxial and both are circular, which perfectly matches the spherical outline of the moon. The surface of the shaped surface can be set with a moon texture, so the shaped surface visible from the light outlet can present the visual effect of a full moon.
[0017] In some embodiments, the shaped surface includes multiple shaped areas distributed circumferentially, and the lamp includes multiple sets of light-emitting elements, with each set of light-emitting elements corresponding to one of the multiple shaped areas; And / or, the light-emitting element includes a plurality of light-emitting lamps, which are lit in a sequential manner; And / or, the light-emitting element includes a light-emitting lamp capable of emitting at least two different colors of light.
[0018] In the above embodiments, multiple circumferential shaped areas on the shaped surface can correspond to different phases of the moon. Each group of light-emitting elements controls the corresponding area individually, which can accurately light up or turn off specific shaped areas to simulate the real state of local brightness and darkness of the moon phases. It can simulate the natural changes of the lunar phases over time, dynamically restore the lunar cycle, more closely match real astronomical phenomena, and provide a stronger sense of immersion, thus improving the user's viewing experience. Users can intuitively perceive the passage of time by observing the color and direction of the lights, thus enhancing their user experience.
[0019] In some embodiments, the luminaire further includes a circuit board located within the receiving cavity, and the light-emitting element is connected to the circuit board.
[0020] In the above embodiments, the light-emitting element is directly connected to the circuit board, reducing the wiring layout and lowering the risk of short circuits and poor contact.
[0021] In some embodiments, the light-emitting element is located on the outer periphery of the shaped element; The lamp also includes a first light-shielding ring, which is disposed around the circuit board and connected to the circuit board and the shaped component.
[0022] In the above embodiments, the light from the light-emitting element is allowed to propagate along the path of the light guide space as much as possible, avoiding light scattering to ineffective areas such as the back of the circuit board and the inside of the shaped component, and allowing as much light as possible to participate in the reflection of the reflective surface, thereby further improving the light utilization rate and making the moon phase brightness more sufficient without additional power.
[0023] In some embodiments, the lamp housing has an abutment surface facing away from the light outlet in the depth direction of the receiving cavity, and the lamp further includes a second light-shielding ring, which is disposed around the circuit board and located on the outer periphery of the light-emitting element, and connects the circuit board and the abutment surface.
[0024] In the above embodiments, the light emitted by the light-emitting element is forced to be transmitted to the reflective surface only along the channel between the shaped element, the inner surface of the lamp housing, and the circuit board, avoiding light scattering to ineffective areas such as the back of the circuit board and the contact surface of the lamp housing, ensuring that all light participates in the reflection of the reflective surface as much as possible, so that the brightness of the lunar shaped surface can be more sufficient and uniform without increasing the power of the light-emitting element.
[0025] In some embodiments, the lamp housing further forms a mounting opening communicating with the receiving cavity, and the lamp fixture further includes: A bottom cover is located on the side of the receiving cavity opposite to the light outlet and blocks the mounting port. The circuit board is disposed on the bottom cover.
[0026] In the above embodiments, the bottom cover directly seals the mounting opening of the lamp housing, isolating external dust, moisture, and foreign objects, preventing them from entering the core components such as the contact circuit board, light-emitting element, first light-shielding ring, and second light-shielding ring, preventing short circuits, oxidation of the light-emitting lamp pins, and cracking of the shaped parts due to moisture, and ensuring that the light emitted by the light-emitting element can accurately hit the corresponding area of the shaped surface through the reflective surface.
[0027] In some embodiments, the luminaire further includes: A bracket is located within the receiving cavity and connected to the shaped component. A mounting post protrudes from the side of the bracket facing the bottom cover. The mounting post abuts against the circuit board and forms a mounting position. The circuit board and the bottom cover have mounting holes corresponding to the mounting position. A connector, which is installed in the mounting position via the mounting hole.
[0028] In the above embodiments, the installation of mounting posts and connectors creates a rigid connection across the entire chain of components, including the molding, bracket, mounting posts, circuit board, connectors, and bottom cover. This makes the core components a unified whole, effectively resisting displacement risks caused by vibration, handling, or thermal expansion and contraction, ensuring that they remain stable even after long-term use. In some embodiments, the bracket has a protruding post on the side facing the bottom cover, the protruding post passing through the circuit board and abutting against the bottom cover.
[0029] In the above embodiment, the protruding post is located in the middle of multiple mounting posts, passes through the circuit board and directly abuts against the bottom cover, and is fixed with the surrounding mounting posts and screws to form a three-dimensional rigid frame, so that the circuit board, bracket and bottom cover are more tightly connected and resist relative displacement caused by vibration, handling or temperature changes.

[0032] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.
[0033] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
[0034] Please see Figure 1 as well as Figure 2 This application provides a lamp 1, which includes a lamp housing 10, a shaped component 20, and a light-emitting component 30.
[0035] Please see Figures 3 to 5The lamp housing 10 serves as the exterior component of the entire lamp 1, forming a receiving cavity 10a and a light outlet 10b communicating with the receiving cavity 10a. The receiving cavity 10a provides installation space for the shaped component 20 and the light-emitting component 30, and can protect the internal components from damage. The inner wall surface of the receiving cavity 10a includes a reflective surface 10c. Specifically, it can be that a vacuum-coated metal reflective layer is provided on the inner wall surface, or the inner wall surface is sprayed with reflective material or the material itself is reflective, without any limitation.
[0036] The decorative element 20 is located inside the receiving cavity 10a. The decorative element 20 has a decorative surface 21 that is visible through the light outlet 10b. The decorative element 20 is the core of the decorative effect or functional display of the lamp 1. It can be designed into any pattern or shape according to the requirements, such as celestial textures, logos, artistic shapes, etc.
[0037] The decorative element 20 receives the light reflected from the reflective surface 10c, diffuses the light a second time, presents a uniform and soft lighting effect, and highlights the details of the design.
[0038] The material of the sculpting component 20 can be ceramic, resin, plaster, or solid wood. In this embodiment, the preferred material of the sculpting component 20 is ceramic, which makes it easy to reproduce the texture of the sculpting component 20 through carving and molding. It also provides uniform reception of reflected light from the reflective surface 10c and good diffuse reflection. If the sculpting surface 21 is the surface of the moon, it is easy to reproduce the delicate texture of the lunar surface, such as craters, through carving and molding. The texture is warm and smooth. Because it provides uniform reception of reflected light from the reflective surface 10c and good diffuse reflection, the outline of the moon is soft and natural after being lit.
[0039] The light-emitting element 30 is disposed in the receiving cavity 10a. The reflective surface 10c and the shaping surface 21 are distributed along the light emission path of the light-emitting element 30. The reflective surface 10c is used to reflect the light emitted from the light-emitting element 30 to the shaping surface 21 to illuminate the shaping surface 21.
[0040] In this embodiment, the reflective surface is distributed along the light-emitting path of the light-emitting element 30. It can recover and directionally reflect the ineffective light that might otherwise be scattered to the inner wall of the receiving cavity 10a to the shaping surface 21. The shaping surface 21 can be clearly lit without increasing the power of the light-emitting element 30, thus reducing light loss.
[0041] The light-emitting element 30 of this application is hidden in the receiving cavity 10a. The light needs to be reflected by the reflective surface 10c before reaching the shaping surface 21. The light is not directly exposed to the light outlet 10b, which reduces the possibility of direct light leakage and makes it difficult for glare to occur, thereby reducing the stimulation to the human eye.
[0042] In addition, the reflective surface 10c of this application can uniformly reflect the light from the light-emitting element 30 to the shaping surface 21. After the reflected light is diffused twice by the shaping surface 21, the visual effect is softer and more stable.
[0043] To further reduce the direct impact of light emitted from the light-emitting element 30 through the light outlet 10b, in one embodiment of this application, please refer to... Figure 5 When viewed from the light outlet 10b towards the inside of the lamp housing 10 along the depth direction of the receiving cavity 10a, the lamp housing 10 blocks the light-emitting element 30.
[0044] The lamp housing 10 blocks and restricts the direct light emission path of the light-emitting element 30, preventing light from overflowing from the light outlet 10b without being reflected by the reflective surface 10c. This allows all light to first contact the reflective surface 10c and then be directionally reflected to the shaped surface 21, making the light more concentrated on the shaped surface 21. This achieves a clearer lighting effect without increasing the power of the light-emitting element 30, further reducing energy consumption.
[0045] After the light-emitting element 30 is blocked by the lamp housing 10, it is difficult to directly observe the messy structure such as the light-emitting element 30 and the circuit from the light outlet 10b. It is easier to see the shape surface 21 directly, which is more visually simple and unified, and can also protect the light-emitting element 30 to a certain extent.
[0046] Following on from the above, please refer to Figure 2 as well as Figure 4 and Figure 5 The light-emitting component 30 includes multiple light-emitting lamps, which are distributed at intervals along the circumference of the shaped component 20 and located on the outer periphery of the shaped component 20. This forms a full-angle light path coverage with the reflective surface 10c. The light shines from all sides of the shaped component 20 onto the reflective surface 10c on the inner wall of the receiving cavity 10a. After reflection, it can fully cover the shaped surface 21, avoiding local dark areas caused by a single-direction light source and making the brightness of the shaped surface 21 more uniform.
[0047] The outline of the light outlet 10b has a first orthographic projection on the plane where the shaped surface 21 is located. The first orthographic projection is located within the shaped surface 21. In this way, the light-emitting element 30 can be better blocked by the lamp housing 10. Even when viewing the inside of the receiving cavity 10a from the side, it is difficult to observe the light-emitting element 30 inside, further reducing the possibility of light emanating from the light outlet 10b and ensuring the user's visual experience.
[0048] Furthermore, when viewed from the light outlet 10b, only the shape surface 21 is visible. There are no extra frame shadows caused by the misalignment between the edge of the light outlet 10b and the shape surface 21, and it is difficult for light leakage or stray light interference to occur. This makes the pattern and texture of the shape surface 21 the visual focus, ensuring the user's visual experience.
[0049] Furthermore, in some embodiments of this application, there is a gap between the shaped component 20 and the lamp housing 10 at least on the periphery of the shaped component 20. The gap is connected to the light outlet 10b. The light reflected by the reflective surface 10c to the shaped surface 21 can be smoothly displayed through the gap. Since the orthographic projection of the light outlet 10b is located inside the shaped surface 21, the gap will not cause the light to overflow. On the contrary, it allows the reflected light to be diffused more concentratedly through the shaped surface 21 and displayed from the light outlet 10b.
[0050] In addition, the gaps form a natural heat dissipation channel, which can dissipate the heat generated by the light-emitting component 30 during operation in a timely manner, and avoid high temperature affecting the life of the component.
[0051] When viewed from the light outlet 10b towards the inside of the lamp housing 10, please refer to... Figure 5 The light-emitting element 30 is located in the non-visible area 1a of the gap.
[0052] like Figure 5 As shown, Figure 5 The surface shown is a cross-section of the entire lamp 1, which is parallel to the depth direction of the receiving cavity 10a and passes through the center of the shaped surface 21 and the light outlet 10b.
[0053] Specifically, the outer contour line of the light outlet 10b has a first vertex A1 and a second vertex A2 on this cross-section, and the inner contour line of the light outlet 10b has a third vertex A3 and a fourth vertex A4 on this cross-section. Figure 4 The orientation shown is for reference. The first vertex A1 and the third vertex A3 are located on the left, and the second vertex A2 and the fourth vertex A4 are located on the right. The straight line connecting the first vertex A1 and the fourth vertex A4 is L1.
[0054] The edge surface of the shaped component 20 is an arc on this cross section. The arc intersects its tangent at the fifth vertex A5. The line connecting A5 and A4 is L2. Thus, when the user observes through the light outlet 10b, the visible area 1b is within the range between the straight lines L1 and L2, regardless of the viewing angle, while other areas correspond to the non-visible area 1a.
[0055] By placing the light-emitting element 30 in the non-visible zone 1a, the possibility of direct light from the light-emitting element 30 entering the human eye is completely eliminated, making it difficult for users to be stimulated by light when viewing the decorative light, thus ensuring the user's viewing experience.
[0056] The non-visible zone 1a design completely hides the internal structure of the light-emitting component 30, and only the shape surface 21 can be seen from the light outlet 10b. Without any interference from internal components, the pattern and texture of the shape surface 21 become the visual focus, improving the user's viewing experience.
[0057] like Figure 5 As shown, and with Figure 5The indicated orientation is for reference. The light-emitting element 30 can be located at the reflective surface 10c, that is, above the line L1 and the line L2, or below the line L1 and the tangent L2. In order to protect the light-emitting element 30 well and ensure the light emission effect, and to ensure that the light strictly passes through the light-emitting element 30-reflective surface 10c-shaped surface 21, in one embodiment of this application, the light-emitting element 30 is located on the side of the shaped surface 21 away from the light outlet 10b.
[0058] That is, the light-emitting element 30 is further away from the light outlet 10b, making it difficult for dust, moisture and external forces to come into contact with it, thus improving the protection of the light-emitting element 30 and ensuring the stability of the light-emitting element 30.
[0059] The light-emitting element 30 is located on the back of the shaped surface 21 and cannot directly illuminate the shaped surface 21 or the light outlet 10b. The light must pass through the outer gap to the reflective surface 10c and then be reflected to cover the shaped surface 21, thus avoiding ineffective direct illumination. It is difficult for any glaring light to be emitted directly. After the light is reflected by the reflective surface, the light that illuminates the shaped surface 21 is diffused again, making the light emitted from the entire light outlet 10b softer and ensuring the user's viewing experience.
[0060] Please see Figure 2 In one embodiment of this application, the light-emitting port 10b is a circular port, the outer periphery of the shaping surface 21 is a circular side, and the light-emitting port 10b and the shaping surface 21 are coaxially arranged.
[0061] The light outlet 10b and the shaped surface 21 are coaxial and both are circular, which perfectly matches the spherical outline of the moon. The surface of the shaped surface 21 can be set with moon texture, so the shaped surface 21 exposed from the light outlet 10b can present the visual effect of a full moon.
[0062] In addition, the circular light outlet 10b is coaxial with the lunar-shaped surface 21. The orthographic projection of the light outlet 10b falls exactly within the lunar-shaped surface 21, and all the reflected light is focused on the circular-shaped surface 21, with no light leakage at the edges, making the circular outline of the moon clearer and simulating the immersive feeling of a full moon in the night sky.
[0063] Furthermore, the shaped surface 21 includes multiple shaped areas distributed circumferentially, and the lamp 1 includes multiple sets of light-emitting elements 30, which are arranged one-to-one with the multiple shaped areas. Each light-emitting element 30 may include at least one light lamp.
[0064] In this way, the multiple circumferential shaped areas of the shaped surface 21 can correspond to different phases of the moon, such as new moon, first quarter moon, full moon, and last quarter moon. The controller on the vehicle can programmatically control when the moon will be in the shape of a new moon and when it will be in the shape of a full moon, etc., according to the date. Each group of light-emitting elements 30 can control the corresponding area separately, and can accurately light up or turn off specific shaped areas to simulate the real state of local brightness and darkness of the moon phases.
[0065] Alternatively, lighting up several design areas simultaneously can create a crescent moon shape, or lighting up more design areas simultaneously can create a convex moon shape. In addition, the various styling areas have different designs, allowing users to customize their appearance according to their needs, thus providing more options.
[0066] In one embodiment of this application, the light-emitting element 30 includes multiple light-emitting lamps, which are lit in sequence. The controller inside the vehicle sets a timing program based on the lunar revolution law. The light-emitting lamps are lit or turned off gradually in the rhythm of new moon-first quarter moon-full moon-last quarter moon-new moon, simulating the natural change of lunar phases over time, dynamically restoring the lunar phase cycle, which is more in line with real astronomical phenomena, has a stronger sense of immersion, and improves the user's viewing experience.
[0067] It can be linked to real time (such as synchronized with the lunar calendar), allowing lamp 1 to automatically switch the lunar phase according to the real date, increasing the fun and practicality of use and improving the user experience.
[0068] Furthermore, the light source can emit at least two different colors of light. For example, when the light source 30 includes 12 light sources, and the 12 light sources are distributed according to the scale of a clock, for example, at 3 o'clock, the light source at the 12 o'clock position lights up white and the light source at the 3 o'clock position lights up red. At 3:30, the light source at the 3 o'clock position lights up red and the light source at the 6 o'clock position lights up white. Users can intuitively perceive the passage of time by observing the color and position of the light, thus improving the user experience.
[0069] It is understandable that the light source can also emit various colors such as purple and blue, and no restrictions are placed here.
[0070] It is understood that the light-emitting element 30 can be directly disposed on the inner wall surface of the lamp housing 10 and connected together by wires to achieve electrical connection with the outside world. Alternatively, the circuit board 40 can be directly disposed so that the light-emitting element 30 is located on the circuit board 40. In this embodiment, the light-emitting element 30 is located on the circuit board 40 for illustrative purposes.
[0071] Please see Figure 2 as well as Figure 5 The lamp 1 also includes a circuit board 40, which is located in the receiving cavity 10a. The light-emitting element 30 is electrically connected to the circuit board 40. The light-emitting element 30 is directly connected to the circuit board 40, which reduces the wiring layout and lowers the risk of short circuits and poor contact.
[0072] The circuit board 40 integrates signal control and transmission functions, such as controlling the lighting, extinguishing and color switching of the lights. It can also control the lighting of multiple different shaped areas to be associated with the moon. In addition, when the shaped surface 21 is associated with the moon, the circuit board 40 can reserve an interface or integrate a chip to be compatible with extended functions such as time linkage, custom lighting rules, and APP control. Without changing the core structure, it can be upgraded to achieve more intelligent effects such as lunar calendar synchronization and remote control, greatly improving flexibility.
[0073] Please see Figure 5 When the light-emitting element 30 is located on the outer periphery of the shaped element 20, the lamp 1 also includes a first light-shielding ring 50, which is arranged around the circuit board 40 and connects the circuit board 40 and the shaped element 20.
[0074] The material of the first light-shielding ring 50 can be a light-shielding modified plastic, such as glass fiber reinforced polypropylene, or a metal material such as aluminum alloy or stainless steel. Of course, it can also be other light-shielding materials in the prior art, and there are no restrictions here.
[0075] The first light-shielding ring 50 can be glued to the circuit board 40. The first light-shielding ring 50 can block light leakage from the side of the light-emitting element 30 and prevent light from different directions from interfering with each other.
[0076] Furthermore, after the first light-shielding ring 50 is set up, it together with the outer periphery of the shaped component 20 and the circuit board 40 to form an annular light-guiding space, that is, the gap mentioned above, so that the light from the light-emitting component 30 can propagate along the path of the light-guiding space as much as possible, avoiding the light from being scattered to ineffective areas such as the back of the circuit board 40 and the inner side of the shaped component 20, and allowing as much light as possible to participate in the reflection of the reflective surface 10c, further improving the light utilization rate, and making the moon phase brightness more sufficient without additional power.
[0077] Furthermore, please continue reading Figure 5 The lamp housing 10 has an abutting surface 10d facing away from the light outlet 10b in the depth direction of the receiving cavity 10a. The lamp 1 also includes a second light-shielding ring 60, which is arranged around the circuit board 40 and located on the outer periphery of the light-emitting element 30, and connects the circuit board 40 and the abutting surface 10d.
[0078] The material of the first light-shielding ring 50 can be the same as that of the second light-shielding ring 60. The first light-shielding ring 50 is used to block the light emitted inward by the light-emitting element 30, and the second light-shielding ring 60 is used to block the light emitted outward by the light-emitting element 30. The circuit board 40 can also block the light emitted by the light-emitting element 30 away from the light outlet 10b. In this way, the light emitted by the light-emitting element 30 is forced to be transmitted only along the channel between the shaped element 20, the inner surface of the lamp housing 10 and the circuit board 40 to the reflective surface 10c. This avoids the light from being scattered to ineffective areas such as the back of the circuit board 40 and the contact surface 10d of the lamp housing 10, ensuring that all light participates in the reflection of the reflective surface 10c as much as possible. The brightness of the lunar shaped surface 21 can be more sufficient and uniform without increasing the power of the light-emitting element 30.
[0079] Please see Figure 4 In one embodiment of this application, the lamp housing 10 also forms an installation port 10e that connects to the receiving cavity 10a, through which the circuit board 40 and the shaped component 20 and other structures can be conveniently installed.
[0080] The lamp 1 also includes a bottom cover 70, which is located on the side of the receiving cavity 10a away from the light outlet 10b and blocks the mounting port 10e. The circuit board 40 is disposed on the bottom cover 70.
[0081] Specifically, the bottom cover 70 and the lamp housing 10 are detachably connected, such as by a snap-fit connection or a bolt connection. Specifically, the bottom cover 70 and the lamp housing 10 are snap-fit connected. For example, the inner side wall of the lamp housing 10 is provided with a groove, and the peripheral side wall of the bottom cover 70 is provided with a protrusion. When the bottom cover 70 and the lamp housing 10 are installed, the protrusion can be embedded into the groove. Of course, it is understood that it is not limited to this snap-fit connection method, and other snap-fit connection methods in the prior art can also be used, which are not limited here.
[0082] The bottom cover 70 directly seals the mounting port 10e of the lamp housing 10, isolating external dust, moisture, and foreign objects, preventing them from entering the core components such as the contact circuit board 40, the light-emitting element 30, the first light-shielding ring 50, and the second light-shielding ring 60, and preventing short circuits, oxidation of the light-emitting lamp pins, and cracking of the shaped part 20 due to moisture.
[0083] As a dedicated mounting carrier for the circuit board 40, it can be pre-set with screw holes, clips and other fixing structures, so that the circuit board 40 can be quickly and accurately fixed on the bottom cover 70, avoiding the displacement of the circuit board 40 in the receiving cavity 10a, thereby ensuring that the light emitted by the light-emitting element 30 can be accurately projected onto the corresponding area of the shaped surface 21 through the reflective surface.
[0084] It is understandable that the bottom cover 70 is also provided with a wiring hole that communicates with the receiving cavity 10a, so that the circuit board 40 can be electrically connected to external control equipment.
[0085] Furthermore, please refer to Figures 6 to 8The lamp 1 also includes a bracket 80 and a connector 90. The bracket 80 is located in the receiving cavity 10a and connected to the molding part 20. The bracket 80 has a mounting post 81 protruding on the side facing the bottom cover 70. The mounting post 81 abuts against the circuit board 40 and forms a mounting position 81a. The circuit board 40 and the bottom cover 70 have mounting holes 40a corresponding to the mounting position 81a. The connector 90 is installed in the mounting position 81a through the mounting hole 40a.
[0086] The bracket 80 and the molding part 20 can be connected by adhesive bonding to avoid damaging the ceramic molding part 20 with fasteners.
[0087] By setting up the mounting column 81 and the connector 90, a rigid connection is formed across the entire chain of the molding component 20, bracket 80, mounting column 81, circuit board 40, connector 90, and bottom cover 70, making the core components a whole. This effectively resists the risk of displacement caused by vibration, handling, or thermal expansion and contraction, ensuring that it is difficult to loosen during long-term use.
[0088] Multiple mounting posts 81 can be provided and distributed at intervals along the circumference of the bottom cover 70 to enhance the stability of the connection.
[0089] In addition, the bracket 80 supports the weight of the molding part 20, preventing the molding part 20 from directly pressing the circuit board 40. The mounting post 81 evenly abuts against the circuit board 40, dispersing the pressure when the connector 90 is locked, and preventing the circuit board 40 from being locally stressed, which could lead to circuit breakage or solder joint detachment.
[0090] In this case, the connector 90 can be a screw, and the mounting position 81a is a bolt hole. During installation, the shaped part 20 is glued to the bracket 80, the first light-shielding ring 50 is glued to the bottom of the shaped part 20, the circuit board 40 is placed from bottom to top, the bottom cover 70 is installed from the back with screws to press the circuit board 40 and the bracket 80 together, the second light-shielding ring 60 is glued to the edge of the circuit board 40, and finally the lamp housing 10 is installed from top to bottom and snapped to the bottom cover 70.
[0091] Furthermore, such as Figure 4 As shown, a protruding post 82 is provided on the side of the bracket 80 facing the bottom cover 70. The protruding post 82 passes through the circuit board 40 and abuts against the bottom cover 70.
[0092] The protruding post 82 is located in the middle of multiple mounting posts 81. After passing through the circuit board 40, it directly abuts against the bottom cover 70. It forms a three-dimensional rigid frame with the surrounding mounting posts 81 and screws, making the connection between the circuit board 40, the bracket 80 and the bottom cover 70 tighter and resisting relative displacement caused by vibration, handling or temperature changes.
[0093] In addition, the support points of the protruding pillars 82 and the mounting pillars 81 are dispersed and symmetrical, and the pressure is evenly transmitted to the bottom cover 70, which avoids localized stress concentration on the circuit board 40, protects the inner layer circuits and surface precision components, and avoids short circuits or poor contact.
[0094] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application shall still fall within the scope of this application.
