[0006] In one embodiment, the strip groove includes two opposing sidewalls and a groove bottom, the two sidewalls being inclined in a direction away from the brim and facing away from each other, and the two sidewalls being smoothly connected to the groove bottom.

[0007] In one embodiment, the top of the hat has multiple inner protruding strips on the side near the brim. The inner protruding strips are V-shaped protrusions with the tips of the V-shapes facing the brim. The multiple inner protruding strips are arranged parallel to the strip-shaped grooves.

[0008] In one embodiment, at least one inner convex strip is synchronized with the bending point of the strip groove.

[0009] In one implementation, the brim surrounds the perimeter of the hat body.

[0010] In one embodiment, the hat body has concave portions on opposite sides facing the inner convex strip, and the concave direction of the concave portions is perpendicular to the extension direction of the inner convex strip.

[0011] As another aspect of the embodiments of this application, the embodiments of this application provide a lamp, including:

[0012] PCB board, with a light source installed on the PCB board;

[0013] In any of the above embodiments, the light-diffusing cover is disposed above the light source and the brim of the light-diffusing cover is attached to the PCB board.

[0014] In one embodiment, the lamp housing is also included, comprising a bottom shell and a top cover. The inner sidewall of the bottom shell is provided with a boss so that the PCB board is mounted on the boss. The top cover is provided with a through hole, and two opposing protrusions are provided in the through hole. In the light-diffusing cover, the opposite sides of the cap body are respectively provided with concave portions, and the shape of the protrusions is adapted to the concave portions.

[0015] As another aspect of the present application, the present application also provides a vehicle that includes a lamp from any of the above embodiments.

[0016] The light-diffusing cover provided in this embodiment, through its cap-like structure design, allows it to be placed over a point light source, collecting not only the light source directly in front of the point light source but also the light emitted from its surroundings. The strip-shaped groove design on the top of the cover allows the light gathered by the point light source to diffuse in the form of a strip of light, increasing the illumination area of ​​the point light source.

[0017] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of this application will become readily apparent from the accompanying drawings and the following detailed description. Attached Figure Description

[0018] In the accompanying drawings, unless otherwise specified, the same reference numerals throughout the various drawings denote the same or similar parts or elements. These drawings are not necessarily drawn to scale. It should be understood that these drawings depict only some embodiments disclosed in this application and should not be construed as limiting the scope of this application.

[0019] Figures 1 to 4 The diagram shows structural schematics of the light-diffusing cover at different angles according to embodiments of this application.

[0020] Figure 5 A schematic diagram of the structure of a lamp provided according to an embodiment of this application is shown.

[0021] Figure 6 An exploded view of the lighting fixture provided according to an embodiment of this application is shown. Detailed Implementation

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0023] This application first provides a light-diffusing cover. Figures 1 to 4 Schematic diagrams showing the structure of the light-diffusing cover at different angles according to embodiments of this application are provided. For example... Figures 5 to 6 As shown, the light distribution cover 100 is used to cover the point light source 210, which is fixed and electrically connected to the PCB board 200. The light distribution cover 100 includes a body, which is hat-shaped. The body includes a brim 110, a body 120, and a top. The body 120 protrudes from the brim 110 and forms a column. The top covers the side of the body 120 opposite to the brim 110. The top 130 has a groove 131 recessed towards the brim 110 on the side away from the brim 110.

[0024] The light-diffusing cover 100 in this embodiment is made of PC (Polycarbonate) material, which gives the light-diffusing cover 100 a high light transmittance.

[0025] The light-diffusing cover 100 provided in this application embodiment has multiple components with a large number of contacts, and the overall structure is stably connected, and can be integrally molded by injection molding.

[0026] The light-diffusing cover 100 provided in this embodiment of the application, through its hat-like structure design, can be placed over the point light source 210, collecting not only the light source from the front of the point light source 210, but also the light source emitted from its surroundings. The size of the hat body 120 is adapted to the size of the point light source 210, so that the point light source 210 can be fitted inside the hat body 120.

[0027] The design of the strip groove 131 of the top 130 allows the light gathered by the point light source 210 to diffuse in the form of a strip of light, thereby increasing the illumination area of ​​the point light source 210.

[0028] In one embodiment, the strip groove 131 extends through the top of the cap 130 along the radial direction of the top. This makes the strip groove 131 as long as possible, further increasing the illumination area of ​​the point light source 210.

[0029] In one embodiment, the strip-shaped groove 131 includes two opposing sidewalls and a groove bottom. The two sidewalls are inclined in a direction opposite to the brim 110, and the two sidewalls are smoothly connected to the groove bottom. Figures 1 to 4As shown, this design makes the groove a V-shaped groove, and the two side walls can emit light sources in the inclined direction, thereby increasing the illumination area of ​​the formed light strip.

[0030] The two side walls are smoothly connected to the bottom of the groove, which makes the light strip emit uniform brightness and avoids sudden changes in brightness that would affect the visual experience.

[0031] In one embodiment, the cap 130 has a plurality of inner protruding strips 132 on the side near the brim 110. The inner protruding strips 132 are V-shaped protrusions with the tip of the V-shape facing the brim 110. The plurality of inner protruding strips 132 are arranged parallel to the strip grooves 131.

[0032] like Figures 1 to 5 As shown, multiple inner convex strips 132 are arranged adjacently to form a wave shape. The arrangement of the inner convex strips 132 can increase the refraction of light and improve the light transmittance.

[0033] The number of inner protruding strips 132 can be set according to the space of the roof 130 and the width of the inner protruding strips 132. For example, three inner protruding strips 132 can be set. In some other application scenarios, two to eight strips can be set.

[0034] In one embodiment, at least one inner convex strip 132 is synchronized with the bending point of the strip groove 131.

[0035] For example Figures 1 to 4 The centrally located inner protrusion 132 bends synchronously with the strip groove 131, extending synchronously towards the crest and trough. This allows the light from the central inner protrusion 132 to be focused and emitted from the strip groove 131, increasing the brightness at the strip groove 131 and creating a light strip effect.

[0036] The width and depth of the inner convex strip 132 and the width and depth of the strip groove 131 can be set according to the power of the point light source 210 and the size of the cap body 120, so that the light from the point light source 210 is emitted from the strip groove 131 with the maximum light power.

[0037] In one embodiment, the brim 110 surrounds the periphery of the hat body 120. This surrounding of the hat body 120 prevents light from the point light source 210 from escaping through the gap between the PCB board 200 and the brim 110, thus avoiding wasted light power. This further improves the focusing effect of the light source and the ambient lighting effect of the light strip.

[0038] In one embodiment, the cap body 120 has concave portions 121 on opposite sides that are recessed toward the inner convex strip 132, and the recessed direction of the concave portions 121 is perpendicular to the extending direction of the inner convex strip 132.

[0039] In one example, the cap body 120 can be a cylindrical shape that is approximately cylindrical. In positions where the inner convex strip 132 is not required, the cap body 120 can be recessed to avoid wasting space.

[0040] The concave portion 121 can extend through the concave part of the cap body 120, or it can be partially concave, such as the part near the top of the cap 130.

[0041] Other configurations of the uniform light cover 100 in the above embodiments can be adopted from various technical solutions that are now and will be known to those skilled in the art, and will not be described in detail here.

[0042] This application also provides a lamp, such as... Figures 5 to 6 As shown, it includes: a PCB board 200, and a light-diffusing cover 100 in any of the above embodiments.

[0043] A light source is provided on the PCB board 200; a diffuser cover 100 is placed on top of the light source, and the brim 110 of the diffuser cover 100 is set against the PCB board 200. This allows the luminaire to achieve the ambient effect of a light strip by using a point light source 210.

[0044] In one embodiment, the lamp housing is also included. The lamp housing includes a bottom shell 320 and a top cover 310. The inner sidewall of the bottom shell 320 is provided with a boss 321 so that the PCB board 200 is mounted on the boss 321. The top cover 310 is provided with a through hole 311 penetrating the top cover 310. Two opposing protrusions 3111 are provided in the through hole 311. In the light-diffusing cover 100, the opposite sides of the cap body 120 are respectively provided with concave portions 121, and the shape of the protrusions 3111 is adapted to the concave portions 121.

[0045] The protrusion 3111 is engaged in the recess 121, which allows the light distribution cover 100 to be stably set up. The point light source 210 is embedded in the cap body 120, locking the position of the point light source 210. This prevents the point light source 210 from shifting due to vibrations caused by vehicle movement, thus improving the product quality of the lamp.

[0046] In one example, a fixing part 111 may also be provided on the brim 110 to fix the diffuser cover 100 to the PCB board 200 or the lamp housing.

[0047] The lighting fixture may also have a wiring harness 400, one end of which is electrically connected to the PCB board 200, and the other end of which is connected to a power source to power the PCB board 200.

[0048] In one example, the light fixture can be used as ambient lighting on the interior door handle of a vehicle, and the wiring harness 400 can be clipped into the door handle.

[0049] Other configurations of the lighting fixtures in the above embodiments can be derived from various technical solutions now and in the future known to those skilled in the art, and will not be described in detail here.

[0050] This application also provides a vehicle that includes a lamp from any of the above embodiments. This lamp can be installed inside the vehicle, allowing power to the point light source 210 to obtain light with a wider illumination area, improving the interior atmosphere and enhancing the user experience.

[0051] Other components of the vehicle in the above embodiments can be derived from various technical solutions now and in the future known to those skilled in the art, and will not be described in detail here.
