Description

Technical Field

[0001] This application relates to the field of lighting fixtures, and particularly to a multi-scenario lampshade and a multi-scenario lighting lamp. Background Art

[0002] Lighting devices play a crucial role in modern life. From household lighting, office lighting to automotive lighting and outdoor lighting, the design and functions of lamps are constantly evolving to meet the lighting needs of different scenarios. Especially in the fields of industry, transportation and safety, efficient and stable lighting devices not only improve work efficiency, but also ensure the safety of personnel and vehicles.

[0003] In lighting devices, high beam and low beam are two common and essential light effect configurations. High beam is mainly used in scenarios that require long-distance lighting, such as highway driving, long-range lighting, etc.; while low beam is used for short-distance lighting to avoid excessive light pollution to the surrounding environment, and is suitable for scenarios such as urban driving, indoor lighting, etc. Since there are significant differences in light intensity, illumination distance and spot shape between high beam and low beam, special consideration needs to be given to how to achieve effective switching and coordination of high beam and low beam when designing lamps.

[0004] Existing lamps usually achieve the switching between high beam and low beam through a single light source combined with a dimming structure. Although this design simplifies the structure of the lamp, it has obvious defects. Limited by the light source power, it cannot provide both high beam and low beam lighting simultaneously, and light attenuation and scattering are prone to occur during the dimming process, affecting the lighting effect. In addition, this design cannot flexibly respond to different lighting requirements in complex lighting environments, restricting the application scenarios and usage effects of the lamps. Therefore, there is an urgent need for a new lamp design that can simultaneously meet the lighting requirements of high beam and low beam and ensure the quality and effect of each light. Summary of the Invention

[0005] To solve the above problems and simultaneously meet the two lighting requirements on the premise of realizing the switching between high beam and low beam, on the first aspect, this application provides a multi-scenario lampshade.

[0006] The multi-scenario lampshade provided by this application adopts the following technical solutions:

[0007] A multi-scenario lampshade includes a cover body, the cover body includes a light incident surface, the light incident surface includes a high beam area and a low beam area, the high beam area is used to receive the light of the high beam lamp, and the low beam area is used to receive the light of the low beam lamp.

[0008] By adopting the above technical solutions, when the lampshade needs to output high beam, the high beam area of the light incident surface can receive the high beam, and when the lampshade needs to output low beam, the low beam area of the light incident surface can receive the low beam.

[0009] Optionally, the cover is provided with a dimming groove, and the high-beam area is arranged in the dimming groove.

[0010] By adopting the above technical solution, the thickness of the cover penetrated by the high beam is small, reducing the divergence of the high beam, making the divergence of the low beam more uniform, making the high beam more convergent and the low beam more divergent.

[0011] Optionally, the cross-sectional shape of the dimming groove is oval.

[0012] By adopting the above technical solution, it is convenient to place multiple high-beam light sources in the dimming groove.

[0013] Optionally, the bottom of the dimming groove is flat.

[0014] By adopting the above technical solution, the high-beam area will not affect the beam angle of the high-beam light source itself.

[0015] Optionally, the multi-scene lamp cover further includes a positioning structure, and the positioning structure is at least two protrusions arranged around the cover.

[0016] By adopting the above technical solution, the lamp cover can provide alignment and support during the assembly process.

[0017] Optionally, the multi-scene lamp cover further includes an anti-fooling structure, and the anti-fooling structure is a protrusion arranged on the side of the cover.

[0018] By adopting the above technical solution, when the installation direction is not aligned, the anti-fooling structure cannot be properly fitted, avoiding the risks caused by human errors.

[0019] Optionally, the positioning structure is a spherical segment type.

[0020] By adopting the above technical solution, the positioning device itself has a certain guiding effect, making the installation smoother.

[0021] Optionally, a Fresnel lens is arranged in the low-beam area of the lamp cover.

[0022] By adopting the above technical solution, the thickness of the low-beam area is reduced, avoiding too large a thickness difference between the low-beam area and the high-beam area.

[0023] In a second aspect, the present application provides a multi-scene lighting lamp.

[0024] The multi-scene lighting lamp provided by the present application adopts the following technical solution:

[0025] A multi-scene lighting lamp includes a lamp cover, a high-beam lamp, and a low-beam lamp, and the lamp cover is the multi-scene lamp cover provided in the first aspect.

[0026] By adopting the above technical solution, since the lamp shade does not need to undertake the function of light dimming, and the switching between high beam and low beam depends on starting different lamps, the high beam and low beam can be output simultaneously.

[0027] Optionally, there are two high beam lamps and two low beam lamps respectively, and the orthographic projections of the high beam lamps and the low beam lamps on the light-emitting surface are alternately arranged on the same circumference.

[0028] By adopting the above technical solution, the light output is more uniform.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] Since the lamp shade no longer undertakes the function of light dimming, and the switching between high beam and low beam of the light does not depend on the change of the shape of the lamp shade, the multi-scene lighting lamp of the present application can output high beam and low beam simultaneously, the lighting effect is more flexible and changeable, and the applicable range is wider.

[0036] The following will further describe the present application in detail Figures 1-4 with reference to the accompanying drawings.

[0037] The embodiment of the present application discloses a multi-scene lamp shade.

[0038] Embodiment 1

[0039] Referring to Figure 1 、 Figure 2 The multi-scene lamp shade includes a housing 1, a positioning structure 2 and an anti-fooling structure 3 provided on the housing 1.

[0040] The housing 1 in this embodiment is a cylinder, including a light-entering surface and a light-emitting surface arranged opposite to the light-entering surface, the light-entering surface is a channel for the optical fiber to enter the lampshade, and the light-emitting surface is a channel for the light to be output. A dimming groove 13 is provided on one side of the light-entering surface of the housing 1, and the cross-sectional shape of the dimming groove 13 can be selected to be rectangular, elliptical or spindle-shaped, etc., and the bottom of the dimming groove 13 is a plane.

[0041] The light incident surface includes a low beam area 11 and a high beam area 12. The low beam area 11 is used to receive light from the low beam lamp, and the high beam area 12 is used to receive light from the high beam lamp. The high beam area 12 is arranged in the dimming groove 13, and the low beam area 11 is arranged in the area of ​​the light incident surface except the dimming groove 13.

[0042] A plurality of positioning structures 2 are arranged around the cover body 1, and the multifunctional lampshade includes at least two positioning structures 2, preferably four. The positioning structure 2 can be optionally a hemispherical, prism-shaped or spherical segment-shaped structure protruding from the side wall of the cover body 1. It should be noted that the volume of the spherical segment should be less than half of the volume of the corresponding sphere, and preferably within the range of one sixth to one quarter of the volume of the corresponding sphere.

[0043] The foolproof structure 3 is arranged on the side of the cover body 1, and is preferably a cube, the edges of which are rounded or straight to facilitate fitting and alignment.

[0044] The implementation principle of Example 1 is:

[0045] The high beam area 12 is arranged in the dimming groove 13. Through the specific shape of the cross section of the dimming groove 13, such as rectangular, elliptical or spindle, the side wall of the dimming groove 13 can effectively gather and guide the light of the high beam. The design of the dimming groove 13 not only enhances the light intensity of the high beam area 12, but also optimizes the directionality of the light through its cross-sectional shape, so that the illumination range of the high beam is wider and farther, meeting the long-distance lighting requirements. This design is particularly important in highway driving or outdoor searchlight applications, because it can provide a farther field of view and improve the safety of the driver or user. At the same time, the bottom of the dimming groove 13 is a plane, which will not destroy the original collimation of the high beam light source, further improving the lighting effect of the high beam, making the light more concentrated and intense.

[0046] The low beam area 11 is set in the area of ​​the light incident surface except the dimming groove 13 to ensure that the light of the low beam can be effectively received and guided. The design of the low beam area 11 allows the light emitting surface to emit more evenly distributed light, avoiding the glare problem caused by excessive light concentration, providing a soft and stable short-distance lighting effect, and is suitable for scenes that need to avoid light pollution. For example, in urban driving or indoor lighting, the design of the low beam area 11 can provide sufficient brightness without interfering with the surrounding environment, making the light both comfortable and safe.

[0047] The reasonable distribution and coordination of the low-beam area 11 and the high-beam area 12 enable the lamp cover to achieve the best effect in various lighting modes.

[0048] The positioning structure 2 is arranged around the cover body 1, effectively ensuring the stability of the multi-scenario lamp cover during installation and use. The positioning structure 2 is preferably hemispherical, frustum-shaped or spherical segment-shaped. These structural shapes not only simplify the manufacturing process but also provide precise alignment and support during assembly, preventing the displacement or loosening of the lamp cover. In particular, the spherical segment-shaped positioning structure 2 has a smooth and inclined surface that helps reduce friction and wear during installation, facilitating installation and extending the service life of the lamp cover. The unique design of the frustum-shaped structure enables the lamp cover and its installation structure to have a good force-bearing and supporting effect. When subjected to external force impacts, it can effectively disperse stress, increasing the stability and reliability of the structure.

[0049] The anti-fooling structure 3 is arranged on the side of the cover body 1 and is preferably a cube with a chamfered or flattened edge line. The design of the anti-fooling structure 3 avoids directional errors during installation, ensuring that the lamp cover can be correctly inserted and aligned, improving the assembly efficiency and reliability. Through its unique shape and positioning, the anti-fooling structure 3 can automatically correct the position during the installation of the lamp cover. If the installation direction is incorrect, it will get stuck, preventing the installation from being completed, reducing the risk of human installation errors, and enhancing the product consistency and user experience. This design simplifies the installation process, ensures the correct installation of the lamp cover in various application scenarios, and further improves the convenience and safety of use.

[0050] In summary, the multi-scenario lamp cover provided in this embodiment can receive both low-beam and high-beam light and output low-beam and high-beam light outward by optimizing the designs of the high-beam area 12, low-beam area 11, dimming slot 13, positioning structure 2, and anti-fooling structure 3. This design breaks through the limitation of traditional lamp cover structures that cannot output two kinds of light simultaneously due to the responsibility of dimming, achieving efficient lighting in multiple scenarios. Whether in industrial lighting, traffic lighting, or outdoor searchlights, it can exert its superior performance, providing users with a reliable lighting solution. Through these innovative structural designs, the present invention not only enhances the functionality of the lamp cover but also greatly extends its service life, reduces maintenance costs, and has broad market prospects.

[0051] Embodiment 2

[0052] Referring to Figure 3 、 Figure 4 The multi-scenario lamp cover includes a cover body 1, a positioning structure 2 and an anti-fooling structure 3 arranged on the cover body 1.

[0053] The cover 1 in this embodiment is a cylinder, including a light incident surface and a light output surface disposed opposite to the light incident surface. The light incident surface is the channel for the optical fiber to enter the lamp cover, and the light output surface is the channel for light to be output. A dimming groove 13 is provided on one side of the light incident surface of the cover 1. The cross-sectional shape of the dimming groove 13 can be selected as a rectangle, an ellipse, a spindle shape, etc., and the bottom of the dimming groove 13 is a plane.

[0054] The light incident surface includes a low beam area 11 and a high beam area 12. The low beam area 11 is used to receive light from the low beam lamp, and the high beam area 12 is used to receive light from the high beam lamp. The high beam area 12 is disposed within the dimming groove 13, and the low beam area 11 is disposed in the area of the light incident surface except the dimming groove 13.

[0055] A plurality of positioning structures 2 are arranged around the cover 1. The multifunctional lamp cover includes at least two positioning structures 2, preferably four. The positioning structure 2 can be selected as a hemispherical, frustum-shaped or spherical segment-shaped structure protruding from the side wall of the cover 1. It should be noted that the volume of the spherical segment should be less than half of the volume of its corresponding sphere, and preferably ranges from one-sixth to one-fourth of the volume of its corresponding sphere.

[0056] The anti-fooling structure 3 is disposed on the side surface of the cover 1, preferably a cube, and the edges of the cube are rounded or flat to facilitate fitting and alignment.

[0057] In particular, a Fresnel lens 4 is provided in the low beam area 11 of this embodiment. The Fresnel lens 4 includes a plurality of concentric ring-shaped convex ribs, and each convex rib includes an outer rib wall and an inner rib wall. Preferably, the outer rib wall is perpendicular to the light incident surface. This design ensures that most of the light intensity is carried by the inner rib wall when the light enters the Fresnel lens 4; the inner rib wall is designed to be concave, forming the effect of a concave lens, so that the light diverges when passing through the inner rib wall, further expanding the irradiation range of the low beam light.

[0058] The height and curvature of each convex rib have been simulated by Zemax, Code V, TracePro, LightTools, etc. in advance to achieve the best optical performance. Generally, the height of the convex rib should be between 0.1 mm and 0.5 mm to ensure that the light can be effectively focused and dispersed; the radius of curvature of the convex rib can be adjusted according to the specific application scenario. The selection of these parameters not only affects the focusing effect of the light, but also determines the overall optical efficiency of the Fresnel lens 4.

[0059] The implementation principle of Embodiment 2 is as follows:

[0060] The Fresnel lens 4 can significantly enhance the light control capability of the low beam area 11. When the low beam light passes through these concentric annular ridges, the light is evenly dispersed to form a uniform and soft light spot, avoiding the glare problem caused by excessive light concentration. This uniform light spot is particularly suitable for scenes that require high-quality lighting and avoid light pollution, such as car low beams and reading lights. In these scenes, the soft light not only provides a comfortable lighting environment, but also effectively reduces light pollution to the surrounding environment.

[0061] In addition, the structural design of the Fresnel lens 4 enables the lampshade to achieve efficient optical performance without increasing the volume and weight. Its thinness not only helps to reduce the overall weight of the lamp, but also increases the design flexibility of the lampshade to meet the design requirements of lamps of different shapes and sizes. In particular, in the multi-scene lampshade of this embodiment, the low beam area 11 is arranged outside the dimming groove 13, which further requires the lens structure of the low beam area 11 to be designed to be thin and light.

[0062] In summary, by arranging the Fresnel lens 4 in the low beam area 11, the multi-scene lampshade of the present invention significantly improves the lighting effect of the low beam lamp, provides more uniform and soft lighting, and maintains the lightness and structural flexibility of the lampshade. This design not only overcomes the shortcomings of traditional heavy lenses, but also provides a more efficient and comfortable optical solution for multi-scene lighting.

[0063] The embodiment of the present application also discloses a multi-scene lighting lamp.

[0064] Example 3

[0065] The multi-scene lighting lamp includes a lampshade, a high beam lamp, and a low beam lamp. The lampshade is the multi-scene lampshade disclosed in Example 1 or Example 2.

[0066] For example, in this embodiment, there are two high beams and two low beams, and the orthographic projections of the high beams and the low beams on the light-emitting surface of the lampshade are cocircular, and the high beams and the low beams are arranged alternately on the circumference. The high beam is directly opposite to the high beam area 12 of the lampshade, and the low beam is directly opposite to the low beam area 11 of the lampshade.

[0067] In the embodiment in which the Fresnel lenses 4 are provided, the number of the Fresnel lenses 4 is the same as the number of the low beam lamps, and the low beam lamps are directly opposite to the center of the Fresnel lenses 4 .

[0068] The implementation principle of Example 3 is:

[0069] The multi-scenario lighting lamp disclosed in this embodiment realizes the effective combination of high beam and low beam, enabling the lighting system to provide high beam and low beam lighting simultaneously. The high beam provides powerful long-distance lighting, suitable for highway driving or outdoor scenarios that require long-distance lighting; while the low beam provides soft short-distance lighting, suitable for urban driving or indoor lighting, avoiding glare to the surrounding environment.

[0070] A significant advantage of this design is that the high beam and low beam can be turned on simultaneously to meet the lighting needs in different scenarios. Users do not need to switch between high beam and low beam by adjusting the lampshade, thus improving the convenience and safety of use. In practical applications, when long-distance and short-distance lighting are required simultaneously, such as in a complex road environment or a large outdoor venue, the multi-scenario lighting lamp of the present invention can provide a more comprehensive and efficient lighting solution.

[0071] In addition, the introduction of the Fresnel lens 4 further enhances the light control ability of the low beam, making the light distribution in the low beam area 11 more uniform and avoiding the problems of uneven light spots and glare in traditional lamps. The design of the Fresnel lens 4 ensures the light dispersion effect, enabling the low beam to provide high-quality illumination and improving the visual comfort and safety of users.

[0072] In summary, by reasonably configuring the high beam and low beam in the lampshade and combining the use of the Fresnel lens 4, the present invention not only improves the overall performance of the lighting lamp but also significantly enhances its ability to adapt to multiple lighting scenarios. This design provides an efficient, flexible and comfortable lighting solution with broad application prospects and market potential.

[0073] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
