Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to lighting devices and vehicles. Background Technology

[0002] As a crucial device for ensuring driving safety, vehicle lights require sufficient light to ensure brightness, and also need to be equipped with lamp covers to protect the light source inside the lights in order to ensure driving safety.

[0003] Prior art 1 provides a vehicle headlight optical module consisting of a decorative frame and a light guide plate. The decorative frame has a light emission window and a decorative back panel with a first reflective pattern. The light guide plate has a light incident end and two reflective surfaces, one of which is located at the light emission window and has a second reflective pattern. The second reflective pattern overlaps with the first reflective pattern. After light enters from the light incident end, it is reflected by the two reflective patterns and finally exits from the light emission window.

[0004] In existing technologies, when light shines through the lamp cover, some of the light is reflected by the lamp cover and cannot be emitted from it, resulting in wasted light resources and affecting the lighting effect of the vehicle lights. Utility Model Content

[0005] The purpose of this invention is to solve the problem of how to improve the effect of vehicle lights.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This application provides a lighting device, including: a light-emitting element, a housing, a light-transmitting cover, and a reflective component; the light-emitting element is used to emit light; the housing has a receiving cavity and a light-emitting port communicating with the receiving cavity, the light-emitting element is disposed in the receiving cavity, and the light emitted by the light-emitting element can be emitted from the light-emitting port; the light-transmitting cover is connected to the housing and covers the light-emitting port; the reflective component is disposed in the receiving cavity, and the reflective component is located on the light-emitting side of the light-emitting element, and the reflective component is provided with a first reflective surface, the first reflective surface facing the light-transmitting cover.

[0008] According to the above technical features, when the light-emitting element emits light, the light is emitted into the light-transmitting cover within the receiving cavity. The vast majority of the light is the first portion, which exits from the light-transmitting cover to achieve the illumination function. A small portion of the light becomes the second portion. Because the incident angle of this second portion is greater than the critical angle for total internal reflection of the light-transmitting cover, it undergoes total internal reflection. This causes the second portion of light to be reflected into the housing and cannot be transmitted outside. Since the first reflective surface of the reflective component faces the light-transmitting cover, the second portion of light, after total internal reflection, can illuminate the first reflective surface. The first reflective surface then reflects the second portion of light a second time, causing it to be reflected back into the light-transmitting cover and transmitted to the outside of the housing. This arrangement effectively avoids the waste of light resources caused by total internal reflection by the light-transmitting cover, thus improving the lighting effect of the lighting device.

[0009] In some embodiments, the reflective component includes a vacuum-plated aluminum layer, the surface of which faces the light-transmitting cover as a first reflective surface.

[0010] Based on the above technical characteristics, the vacuum-plated aluminum layer has a high reflectivity, which can reach over 90%. The vacuum-plated aluminum layer can effectively improve the reflectivity of the total internal reflection of the light-transmitting cover, thereby increasing the light utilization rate of the lighting device.

[0011] In some embodiments, the reflective component includes: a body and a plurality of reflective protrusions; a first reflective surface is disposed on the body; and the plurality of reflective protrusions are disposed on the first reflective surface.

[0012] Based on the above technical features, setting multiple reflective protrusions on the first reflective surface can significantly improve the optical performance and practicality of the first reflective surface.

[0013] In some embodiments, the reflective bumps include raised dots, and a plurality of raised dots form a frosted texture structure.

[0014] Based on the above technical features, the frosted texture structure formed by multiple protrusions enables the light reflected by the light-transmitting cover to be scattered at multiple angles, effectively reducing the reflection intensity of the first reflective surface, reducing the glare caused by direct strong light, avoiding affecting the vision of pedestrians outside the vehicle, and improving pedestrian comfort and safety.

[0015] In some embodiments, the reflective protrusion has a second reflective surface that is inclined relative to the first reflective surface.

[0016] Based on the above technical features, the second reflective surface can adjust the light reflected by the total reflection of the light-transmitting cover onto the reflective component, so that the total reflected light can illuminate the specific position required by the user.

[0017] In some embodiments, the housing includes: a bottom wall, a first side wall, and a second side wall; a light-emitting element is connected to the bottom wall, the first side wall and the second side wall are connected to the side of the bottom wall facing the light-emitting element, and the ends of the first side wall and the second side wall away from the bottom wall define a light-emitting port; the first side wall has a mounting portion, and along the direction from the first side wall to the second side wall, the projection of the mounting portion is located outside the projection of the second side wall, and a reflective element is disposed on the mounting portion.

[0018] Based on the above technical features, by making the first reflective surface of the reflective component face the light-transmitting cover while the light-transmitting cover also faces the reflective component, more of the light reflected by the light-transmitting cover can be concentrated on the reflective component.

[0019] In some embodiments, the light-transmitting cover has an arc-shaped structure and is recessed in the direction away from the receiving cavity.

[0020] Based on the above technical features, the arc-shaped structure has good optical performance. Its curved surface can naturally refract and reflect the light emitted by the internal light source, achieve a more uniform light field distribution, reduce glare and uneven brightness, and improve the lighting or display effect.

[0021] In some embodiments, the reflective component further includes a blocking portion disposed on the periphery of the first reflective surface and protruding from the first reflective surface.

[0022] Based on the above technical features, the blocking part can block light that cannot be effectively reflected to the position that needs illumination due to a special incident angle, so as to avoid light spreading to the position that does not need illumination and causing light pollution, and effectively improve the anti-glare capability of the reflective component.

[0023] In some embodiments, the lighting device further includes: a rotating bracket connected between the reflective component and the housing, wherein the rotating bracket is rotatable relative to the housing and / or the reflective component is rotatable relative to the rotating bracket.

[0024] Based on the above technical features, the angle of the reflective component can be adjusted by rotation so that the reflective component can reflect the light totally reflected by the light-transmitting cover to the specific position required.

[0025] This application also provides a vehicle equipped with the lighting device provided in this application. Attached Figure Description

[0035] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0037] This application provides a vehicle, which may be, for example, a sedan, a truck, or a special vehicle. The vehicle includes a body and a lighting device mounted on the body. In some possible embodiments, the lighting device may be located at the front of the vehicle to function as a low beam or high beam, etc. In another possible embodiment, the lighting device may be located at the rear of the vehicle to function as a brake light or a warning light, etc. This application does not limit the specific structure of the lighting device; it can be selected according to the actual situation.

[0038] In other embodiments, the lighting device can also be used on other equipment, such as ships, aircraft, machinery, etc. This application does not specifically limit this application.

[0039] like Figure 1 and Figure 2As shown, in some possible embodiments, the lighting device may include a light-emitting element 1. Exemplarily, the light-emitting element 1 may be a light-emitting diode module or a halogen lamp, and the selection of the light-emitting element 1 can be based on actual factors such as brightness and power requirements. In some embodiments, the light-emitting element 1 may be a composite structure of a lens module and a light-emitting diode to achieve efficient light distribution and focusing. Simultaneously, the integration of the lens module and the light-emitting diode into a single, compact module facilitates installation in space-constrained devices, reducing the need for external reflectors or complex optical components.

[0040] The lighting device may also include a housing 2. In some possible embodiments, the housing 2 may be provided with a receiving cavity 6 and a light-emitting port, with the light-emitting port communicating with the receiving cavity 6 so that the receiving cavity 6 can communicate with the external environment. A light-emitting element 1 may be disposed within the receiving cavity 6. Exemplarily, the light-emitting element 1 may be bolted to the inner wall of the housing 2, or it may be riveted to the inner wall of the housing 2. This application does not limit the specific connection method between the light-emitting element 1 and the housing 2; the specific method can be selected based on actual factors such as cost and manufacturing process. The light-emitting side of the light-emitting element 1 may face the light-emitting port so that the light emitted by the light-emitting element 1 can be emitted from the light-emitting port.

[0041] The lighting device may also include a light-transmitting cover 3. In some possible embodiments, the light-transmitting cover 3 may be provided with a locking block, and the light outlet of the housing 2 may be provided with a locking groove. The light-transmitting cover 3 is held in the locking groove by the locking block to connect the light-transmitting cover 3 to the housing 2. In other possible embodiments, the light-transmitting cover 3 and the housing 2 may also be connected by bolts. The light-transmitting cover 3 covers the light outlet, which can be understood as the light-transmitting cover 3 completely covering the light outlet, so that the light-transmitting cover 3 can provide protection for the light-emitting element 1 and the internal structure of the lighting device. During the operation of the lighting device, the light emitted by the light-emitting element 1 can shine onto the light-transmitting cover 3 and then be transmitted to the outside from the light-transmitting cover 3. For example, the material of the light-transmitting cover may be polycarbonate, or it may be acrylic resin. This application does not specifically limit the material of the light-transmitting cover, and it can be selected according to actual needs such as cost and process.

[0042] The lighting device may further include a reflective component 4. In some possible embodiments, the reflective component 4 may be disposed within the receiving cavity 6 and located on the light-emitting side of the light-emitting element 1. This can be understood as the reflective component 4 being located near the light-emitting position of the light-emitting element 1. Exemplarily, the reflective component 4 may be connected to the inner wall of the housing 2 via a slot, or it may be connected to the inner wall of the housing 2 via rivets. This application does not limit the connection method between the reflective component 4 and the housing 2; the method can be selected based on the size of the receiving cavity 6 and actual factors such as manufacturing process. The reflective component 4 is provided with a first reflective surface 401, which faces the light-transmitting cover 3. Exemplarily, the first reflective surface 401 may be a plane capable of reflecting light or a curved surface capable of reflecting light. The reflective component 4 may be a block structure with the first reflective surface 401, or it may be a plate structure, with the plate surface of the reflective component 4 serving as the first reflective surface 401.

[0043] It should be noted that when the first reflective surface 401 of the reflective component 4 reflects the light that has been totally reflected by the light-transmitting cover 3, the angle of the reflective component 4 can be adjusted so that the incident angle of the light reflected from the first reflective surface 401 to the light-transmitting cover 3 is less than the critical angle of total internal reflection of the light-transmitting cover 3, so as to avoid the light reflected from the first reflective surface 401 to the light-transmitting cover 3 being totally internally reflected again on the light-transmitting cover 3.

[0044] When the light-emitting element 1 emits light, the light is emitted into the light-transmitting cover 3 within the receiving cavity 6. The vast majority of the light is the first portion, which exits from the light-transmitting cover 3 to achieve the illumination function. A small portion of the light is the second portion. Because the incident angle of this second portion is greater than the critical angle for total internal reflection of the light-transmitting cover 3, it undergoes total internal reflection on the cover 3, causing it to be reflected into the housing 2 instead of transmitting through. Since the first reflective surface 401 of the reflective element 4 faces the light-transmitting cover 3, the second portion of light, after total internal reflection, can reach the first reflective surface 401. The first reflective surface 401 then reflects the second portion of light a second time, causing it to be reflected back onto the light-transmitting cover 3 and transmitted to the outside of the housing 2. This arrangement effectively avoids the waste of light resources caused by total internal reflection by the light-transmitting cover 3, thus improving the illumination effect of the lighting device.

[0045] like Figure 1As shown, in some possible embodiments, the reflective component 4 may include a vacuum-plated aluminum layer, the surface of which faces the light-transmitting cover 3 as a first reflective surface 401. The vacuum-plated aluminum layer is formed by heating and evaporating aluminum under high vacuum conditions using physical vapor deposition (PVD) technology, causing it to condense on the surface of a substrate to form a dense and uniform thin film of metallic aluminum. In the optical field, the vacuum-plated aluminum layer has high reflectivity (especially in the visible and near-infrared bands), with a reflectivity reaching over 90%. It also exhibits good ultraviolet light reflection capability and excellent stability. Furthermore, the aluminum layer can serve as a base for optical thin films, further enhancing reflectivity or achieving specific spectral responses in conjunction with dielectric films. It offers advantages such as low cost, mature technology, and good adhesion.

[0046] In some possible embodiments, the reflective component 4 may include a plate, on the surface of which a vacuum-plated aluminum layer may be provided, such that the surface of the plate with the vacuum-plated aluminum layer faces the light-transmitting cover 3, and the vacuum-plated aluminum layer has a good reflectivity, so that the vacuum-plated aluminum layer can reflect the light that is totally reflected by the light-transmitting cover 3 back to the light-transmitting cover 3 with a better reflection effect, and then transmit it to the external environment of the housing 2 through the light-transmitting cover 3, further reducing the waste of light resources.

[0047] like Figure 2 As shown, in some embodiments, the reflective component 4 includes a body 402 and a plurality of reflective protrusions 403, and a first reflective surface 401 is provided on the body 402. For example, the body 402 may be a plate-like structure, and one surface of the plate-like structure serves as the first reflective surface 401. The body 402 may also be an arc-shaped plate, and the arc-shaped surface of the arc-shaped plate may serve as the first reflective surface 401. This application does not limit the specific structure of the body 402, and the body 402 may be selected according to the reflection requirements and actual conditions such as the manufacturing process.

[0048] Multiple reflective protrusions 403 are disposed on the first reflective surface 401. In some possible embodiments, the reflective protrusions 403 may be arranged in an array. In other possible embodiments, the reflective protrusions 403 may be randomly distributed. Exemplarily, the multiple reflective protrusions 403 may be formed on the first reflective surface 401 by etching or by engraving. This application does not limit the specific forming method of the multiple reflective protrusions 403, and the forming method of the reflective protrusions 403 can be selected according to the reflection requirements and actual conditions such as the process. In some possible embodiments, a vacuum-plated aluminum layer may be disposed on the body 402, and then multiple reflective protrusions 403 may be disposed on the surface of the vacuum-plated aluminum layer facing the light-transmitting cover 3.

[0049] The placement of multiple reflective protrusions 403 on the first reflective surface 401 significantly enhances its optical performance and practicality. These protrusions 403 effectively disrupt the regular reflection path of incident light, dispersing concentrated, intense light into diffuse reflections in multiple directions. This reduces glare, prevents light pollution, and improves visual comfort. It also prevents light reflected from the reflective component 4 from passing through the light-transmitting cover 3 and obstructing the view of pedestrians outside the vehicle. Furthermore, a specific arrangement of the protrusions 403 (such as microprisms or a hemispherical array) enhances the retroreflection performance, significantly improving retroreflection efficiency and giving the reflective component 4 a better reflective effect, further increasing light utilization. In addition, the protrusions 403 increase the surface roughness of the first reflective surface 401, helping to maintain its long-term effectiveness. Therefore, the placement of multiple reflective protrusions 403 on the first reflective surface 401 optimizes the optics of the reflective component 4, significantly improving its functionality and safety.

[0050] In some possible embodiments, the reflective protrusion 403 includes bumps, and multiple bumps form a frosted texture structure. Exemplarily, the bumps can be hemispherical, frustum-shaped, ellipsoidal, or polyhedral in shape. In some possible embodiments, the height of the bumps can be 1-100 micrometers, and the spacing between adjacent bumps can be 2-200 micrometers. This application does not specifically limit the height of the bumps or the thickness of adjacent bumps; the spacing and height of adjacent bumps can be selected according to process requirements and cost.

[0051] For example, the bumps can be formed by spraying fine particles (such as alumina, glass beads or quartz sand) onto the material surface under high pressure, using physical impact to create a micron-level uneven structure on the surface, forming a uniform frosted texture. This setup is inexpensive and simple. When the cost is reasonable and the process requirements are low, the above process can be used to form bumps on the first reflective surface 401.

[0052] For example, bumps can also be formed by a controlled chemical reaction between an acidic or alkaline etching solution and the substrate, selectively dissolving surface areas to create a micro-rough structure. By adjusting the composition, concentration, temperature, and time of the etching solution, the depth and uniformity of the frosted texture can be precisely controlled. The above process achieves high precision in forming bumps on the first reflective surface 401 without generating mechanical stress or material deformation, avoiding problems such as burrs and cracks that may occur in traditional processing. Furthermore, this process provides good uniformity in modifying the material surface, allowing for precise control of etching depth and roughness, thereby obtaining a consistent frosted effect.

[0053] The frosted texture structure formed by multiple protrusions enables the light from the total reflection of the light-transmitting cover 3 to the reflective component 4 to be scattered at multiple angles, effectively reducing the reflection intensity of the first reflective surface 401, reducing the glare caused by direct strong light, avoiding affecting the vision of pedestrians outside the vehicle, and improving the comfort and safety of pedestrians.

[0054] like Figure 2 As shown, in some other possible embodiments, the reflective protrusion 403 has a second reflective surface 4031, which is inclined relative to the first reflective surface 401. Specifically, the first reflective surface 401 may be provided with a patterned structure capable of reflecting the path, the patterned structure protruding from the first reflective surface 401, and the second reflective surface 4031 formed on the patterned structure. Exemplarily, the patterned structure can be prepared on a metal mold using electron beam writing or photolithography, and then transferred onto the body 402 by hot pressing or ultraviolet curing, so that the first reflective surface 401 of the body 402 forms a reflective protrusion 403 with the second reflective surface 4031. Alternatively, the reflective protrusion 403 can be directly engraved on the reflective component 4 using a laser to form the patterned structure.

[0055] For example, the reflective protrusion 403 can be in the shape of a triangular prism. The first side of the reflective protrusion 403 is attached to the first reflective surface 401, and the second side of the reflective protrusion 403 is inclined relative to the first side. When the first side of the reflective protrusion 403 is attached to the first reflective surface 401, the first reflective surface 401 and the second side can be inclined, at which point the second side can serve as the second reflective surface 4031. The reflective protrusion 403 can also be a frustum, having two mutually inclined planes. One plane is attached to the first reflective surface 401, and the other plane is inclined relative to the first reflective surface 401. This application does not limit the specific shape of the reflective protrusion 403; it can be selected according to actual process requirements and reflection angle requirements. For example, the inclination angle between the first reflective surface 401 and the second reflective surface 4031 can be an acute angle, such as 30°, 45°, or 50°, which can be adjusted according to the angle requirements of the light.

[0056] Because the second reflective surface 4031 is tilted relative to the first reflective surface 401, the second reflective surface 4031 can reflect the light that is totally reflected by the light cover 3 to the position where the user needs to be illuminated. For example, by adjusting the angle between the second reflective surface 4031 and the first reflective surface 401 and the orientation of the second reflective surface 4031, the light that is totally reflected by the light guide can be reflected to the ground 5-15 meters in front of the vehicle, or the totally reflected light can be reflected outside the housing 2 so that the highest point of the light is 0.8-1 meters above the ground, so as to prevent the light from making pedestrians feel uncomfortable, thereby increasing the safety of vehicle driving.

[0057] like Figure 3 As shown, in some possible embodiments, the reflective component 4 may further include a blocking portion 404, which is disposed on the periphery of the first reflective surface 401 and protrudes from the first reflective surface 401. For example, the blocking portion 404 may be a blocking block, which is bonded to the periphery of the first reflective surface 401 by means of adhesive bonding. The blocking portion 404 may also be integrally formed with the body 402.

[0058] As a physical light-shielding structure, the blocking part 404 can effectively block stray light from non-working areas, preventing uncontrolled specular reflection or scattered light from ambient light or strong light sources (such as oncoming vehicle headlights at night) from entering the first reflective surface 401 from the side, thereby reducing glare. This avoids temporary visual impairment or attention interference for pedestrians caused by strong light reflection. At the same time, the blocking part 404 can actively limit the effective reflection angle range of the first reflective surface 401 to control the reflection angle of the total internally reflected light from the light-transmitting cover 3 on the first reflective surface 401. The first reflective surface 401 reflects most of the total internally reflected light to the position that needs illumination, while the blocking part 404 can block light that cannot be effectively reflected to the position that needs illumination due to a special incident angle, thus preventing light from spreading to the position that does not need illumination and causing light pollution, effectively improving the anti-glare capability of the reflective component 4.

[0059] like Figure 1 and Figure 2 As shown, in some possible embodiments, the lighting device may further include a rotating bracket 5, which is connected between the reflective component 4 and the housing 2, and the rotating bracket 5 is rotatable relative to the housing 2 and / or the reflective component 4 is rotatable relative to the rotating bracket 5. The reflective component 4 is connected to the inside of the housing 2 via the rotating bracket 5, and the rotating bracket 5 enables the reflective component 4 to rotate relative to the housing 2.

[0060] This configuration allows the reflective component 4 to rotate via the rotating bracket 5, adjusting the reflection angle of the reflective component 4 on the light reflected by the light-transmitting cover 3. This enables the operator to direct the light reflected by the light-transmitting cover 3 to the desired location. For example, the operator can adjust the angle of the reflective component 4 to converge the light reflected by the light-transmitting cover 3 with the main light emitted by the light-emitting element 1, which can directly transmit outside the light-transmitting cover 3, thereby increasing the illumination brightness of the lighting device. Alternatively, the operator can adjust the angle of the reflective component 4 to reflect the light reflected by the light-transmitting cover 3 to one side of the main light source, thereby increasing the illuminated area of ​​the lighting device.

[0061] In some possible embodiments, the connecting bracket can be a ball-joint structure, with a ball-joint structure connected to the back of the reflective component 4. This ball-joint structure can be embedded in a ball socket provided on the inner wall of the housing 2, and, in conjunction with an elastic compression spring or damping ring, allows the reflective component 4 to tilt and rotate freely within a certain angle range. The rotational damping can be controlled by adjusting the clamping force. In other possible embodiments, the connecting bracket can also be a composite bracket with a gear transmission mechanism. A small gear is installed on the back of the reflective component 4, meshing with a drive gear inside the housing 2. The gear is driven to rotate by a motor, thereby precisely controlling the rotation angle of the reflective component 4. This structure allows for fine-tuning and positioning locking. A controller can also be installed inside the vehicle to control the motor, allowing the operator to adjust the reflective component 4 from inside the vehicle.

[0062] like Figure 1 As shown, in some possible embodiments, the housing 2 may include: a bottom wall 201, a first side wall 202, and a second side wall 203; the light-emitting element 1 is connected to the bottom wall 201, and the first side wall 202 and the second side wall 203 are connected to the side of the bottom wall 201 facing the light-emitting element 1, with the ends of the first side wall 202 and the second side wall 203 away from the bottom wall 201 defining a light outlet; for example, the first side wall 202 and the second side wall 203 may be two arc-shaped side walls, and by joining the two arc-shaped side walls and the bottom wall 201, a cylindrical housing 2 with an opening on one side is formed. The first side wall 202, the second side wall 203, and the bottom wall 201, when joined together, may also be a square tube with an opening on one side. The first sidewall 202 and the second sidewall 203 can be connected by a slot and a block. The first sidewall 202 can also be integrally formed with the second sidewall 203. This application does not limit the specific structure and connection method of the first sidewall 202, the second sidewall 203 and the bottom wall 201. They can be selected according to actual needs such as process and cost.

[0063] The first sidewall 202 has a mounting portion 2021. Along the direction from the first sidewall 202 to the second sidewall 203, the projection of the mounting portion 2021 is outside the projection of the second sidewall 203. This can be understood as follows: when the housing 2 is placed vertically, the bottom wall 201 is at the lowest point of the housing 2, while both the first sidewall 202 and the second sidewall 203 extend upwards. Based on the bottom wall 201, the height of the first sidewall 202 is higher than the height of the second sidewall 203; the first sidewall 202 is higher than the second sidewall. Part 203 can serve as mounting part 2021, allowing the plane defining the light outlet at the ends of the first sidewall 202 and the second sidewall 203 away from the bottom wall 201 to be inclined to the bottom wall 201 of the housing 2. A light-transmitting cover 3 is placed over the light outlet, so that the light-transmitting cover 3 is tilted relative to the bottom wall 201, ensuring that the first reflective surface 401 of the reflecting component 4 faces the light-transmitting cover 3, while the light-transmitting cover 3 also faces the reflecting component 4. This allows the light totally reflected by the light-transmitting cover 3 to reach the reflecting component 4. It is important to note that when setting the reflecting component 4, it is crucial to avoid obstructing the light emitted by the light-emitting element 1.

[0064] In some possible embodiments, the total internal reflection light path of the light-transmitting cover 3 can be simulated using optical simulation software, and the installation position of the reflective component 4 can be determined based on the simulation results. In other embodiments, the specific position of the reflective component 4 can be obtained through multiple experiments.

[0065] like Figure 1 and Figure 2 As shown, in some possible embodiments, the light-transmitting cover 3 has an arc-shaped structure, and the light-transmitting cover 3 is recessed away from the receiving cavity 6. First, the arc-shaped structure has good optical performance; its curved surface can naturally refract and reflect the light emitted by the internal light source, achieving a more uniform light field distribution, reducing glare and uneven brightness, and improving the lighting or display effect. Second, the arc-shaped cover has high structural strength and compressive strength, effectively dispersing external impacts and improving wind pressure resistance, impact resistance, and shock resistance, making it suitable for outdoor or harsh environments. In addition, the light-transmitting cover 3 is recessed away from the receiving cavity 6, which helps to prevent rainwater or dust from accumulating on the outside of the light-transmitting cover 3, thus preventing the light from the lighting device from being blocked. In other possible embodiments, the light-transmitting cover 3 can also be a flat structure. This application does not limit the specific shape of the light-transmitting cover 3, and it can be selected according to actual needs such as process and cost.
