[0039] Embodiment one
[0040] In combination Figures 1 to 5 The present application provides a light guide 10, the light guide 10 is long strip-shaped, the light guide 10 includes a light entrance surface 101 and a light guide cross section 210, the light entrance surface 101 is located at one end of the light guide 10 in the length direction X, and the light guide cross section 210 is perpendicular to the length direction X, and the light guide cross section 210 includes a reflection curved surface 220 and a light exit curved surface 230, and the light exit curved surface 230 is arranged around the reflection curved surface 220 and is spaced apart.
[0041] Wherein, the light rays enter the light guide 10 through the light entrance surface 101, are dispersed and reflected to the light exit curved surface 230 through the reflection curved surface 220, and are finally dispersed and emitted through the light exit curved surface 230. In other words, the light rays enter the inside of the light guide 10 through the light entrance surface 101, the irradiation area is enlarged through the dispersion of the reflection curved surface 220, and the light rays are further dispersed and emitted through the light exit curved surface 230. The double dispersion mechanism makes the light rays no longer limited to a small emission area, and a wider irradiation area is realized. The reflection curved surface 220 has a large surface area compared with a plane, which is beneficial to reflecting the light rays in all directions. The light exit curved surface 230 wraps the reflection curved surface 220, can receive reflected light rays from all directions, and further enlarges the emission area. In addition, due to the multiple dispersion of the light rays on the reflection curved surface 220 and the light exit curved surface 230, the emitted light rays are more uniform.
[0042] In this embodiment, the light guide 10 can be used in combination, and a plurality of light guides 10 are spaced apart along the width direction Y. The irradiation areas of the plurality of light guides 10 are spliced along the width direction Y, further enlarging the irradiation area and improving the uniform light emission.
[0043] In the present application, the light exit curved surface 230 extends along the length direction X. The curvature of the light exit curved surface 230 can be designed to adjust the refraction angle of the light rays, which is beneficial to controlling the boundary of the irradiation area. Specifically, by adjusting the curvature and position of the light exit curved surface 230, the boundary position, irradiation size and shape of the irradiation area can be flexibly adjusted to meet different lighting needs.
[0044] The irradiation width of a general light guide 10 is only the irradiation width as large as the light guide 10. In combination Figure 8 The light guide cross section 210 of the light guide 10 provided by the present application has a width of 20 mm, and the irradiation width is greater than 80 mm, which is more than four times the width of the light guide. Of course, in combination Figure 4 and Figure 5 The light exit curved surface 230 can also be adjusted and controlled to change the refraction angle and control the direction of the light rays, so that the light rays can be uniformly irradiated to a certain area, further enlarging the irradiation width.
[0045] In some embodiments, in combination Figure 1、 Figure 4 and Figure 5 The light-out curve surface 230 includes a first convex curve surface 231 and a second convex curve surface 232 connected in sequence along the width direction Y, and the first convex curve surface 231 and the second convex curve surface 232 are located on opposite sides of the reflection curve surface 220 in the width direction Y. Compared with a plane or a concave surface, the first convex curve surface 231 and the second convex curve surface 232 can better disperse light. When the light is reflected from the reflection curve surface 220 to the light-out curve surface 230, the shape of the first convex curve surface 231 and the second convex curve surface 232 causes the light to scatter at a wider angle, thereby further enhancing the dispersion effect of the light and achieving a wider illumination area and a more uniform lighting effect.
[0046] In addition, the design of the convex curve surface can more effectively utilize the light reflected by the reflection curve surface 220, reducing the loss and waste of light. Compared with a plane or a concave surface design, the convex curve surface can better guide the light to the area that needs to be illuminated, thereby improving the lighting efficiency.
[0047] Specifically, by adjusting the curvature and position of the first convex curve surface 231 and the second convex curve surface 232, the refraction angle and direction of the light can be flexibly controlled, and the design of the light-out curve surface 230 can be customized according to specific lighting requirements, such as the boundary position, size and shape of the illumination area, to achieve the best lighting effect.
[0048] In one embodiment, in combination with Figure 4 and Figure 5 The first convex curve surface 231 and the second convex curve surface 232 are symmetrically distributed about the length direction X, and the refraction direction of the light by the first convex curve surface 231 and the second convex curve surface 232 is consistent, thereby avoiding the situation that the light is excessively concentrated or weakened on one side, achieving more uniform light distribution, and ensuring that the light is uniformly dispersed in the width direction Y of the light guide body 10.
[0049] In one embodiment, in combination with Figure 4 and Figure 5 The curvature of the first convex curve surface 231 gradually decreases towards the second convex curve surface 232, i.e. the surface of the first convex curve surface 231 gradually flattens towards the second convex curve surface 232, which facilitates a relatively gentle transition of the surface between the first convex curve surface 231 and the second convex curve surface 232. Correspondingly, the exit angle of the outgoing light gradually transitions from the first convex curve surface 231 to the second convex curve surface 232, improving the uniformity of the outgoing light and avoiding over-brightness or over-darkness in the area between the first convex curve surface 231 and the second convex curve surface 232.
[0050] In addition, since the curvature of the first convex surface 231 gradually decreases, the light rays will be more uniformly dispersed in various directions when exiting through the first convex surface 231, which helps to reduce the excessive concentration or weakening of light rays in a certain area, thereby achieving a more uniform lighting effect.
[0051] In one of the embodiments, in combination with Figure 4 and Figure 5 , the curvature of the second convex surface 232 gradually decreases towards the direction close to the first convex surface 231, i.e., the surface of the second convex surface 232 gradually flattens towards the direction close to the first convex surface 231, which facilitates a more gradual transition of the surface between the first convex surface 231 and the second convex surface 232. Correspondingly, the exit angle of the exiting light rays from the second convex surface 232 to the first convex surface 231 transitions smoothly, which improves the uniformity of the exiting light rays and avoids excessive brightness or darkness in the area between the first convex surface 231 and the second convex surface 232.
[0052] In addition, since the curvature of the second convex surface 232 gradually decreases, the light rays will be more uniformly dispersed in various directions when exiting through the second convex surface 232, which helps to reduce the excessive concentration or weakening of light rays in a certain area, thereby achieving a more uniform lighting effect.
[0053] In some embodiments, in combination with Figure 2 , Figure 6 and Figure 7 , the reflective surface 220 includes a plurality of circular-arc convex surfaces distributed along the length direction X. The circular-arc convex surfaces are convexly arranged towards the light-exit surface 230 and can receive the light rays incident from the light-incident surface 101, and then reflect the light rays to the light-exit surface 230, effectively controlling the light path. The plurality of circular-arc convex surfaces are distributed along the length direction X, so that the circular-arc convex surfaces at different length positions reflect the light rays to the light-exit surface 230 at different length positions, so that the light-exit surface 230 receives the light rays reflected by the circular-arc convex surfaces and disperses the light rays in the length direction X.
[0054] In addition, the circular-arc convex surfaces have consistent curvature, which can uniformly reflect the light rays in various radial directions, improving the uniformity of light reflection. Optionally, the circular-arc convex surfaces have an angle of 180°.
[0055] In this embodiment, by adjusting the number, position, size and curvature of the reflective surface 220, the boundary and shape of the illumination area can be flexibly controlled. This flexibility enables the light guide body 10 to adapt to more diversified lighting needs, such as different sizes, shapes and positions of the illumination area.
[0056] In one of the embodiments, in combination with Figure 2 , Figure 3 and Figure 7The two sides of the arc convex surface in the length direction X are provided with transition fillets, which reduces the abrupt change of light at the edge of the reflection curved surface 220, so that the light reflected by the reflection curved surface 220 is more uniform and soft in the length direction X, and then the light reflected to the light-out curved surface 230 is uniformly distributed in the length direction X. Moreover, the transition fillets help to reduce light loss and improve light transmission efficiency.
[0057] In some embodiments, in combination with Figure 6 and Figure 7 , the side of the light guide body 10 away from the light-out curved surface 230 is provided with a cylindrical groove 221, and the groove bottom of the cylindrical groove 221 is provided with a plurality of arc grooves 222. The cylindrical groove 221 and the arc grooves 222 are both taken the length direction X as the rotation axis, and the groove bottom of the arc grooves 222 forms an arc convex surface, that is, from the outside of the light guide body 10, the groove bottom of the arc grooves 222 is concave, but from the inside of the light guide body 10, the concave groove bottom outside is convex to the light-out curved surface 230, forming an arc convex surface. Based on this, the cylindrical groove 221 and the arc grooves 222 are processed by removing materials, and then a plurality of arc convex surfaces are formed which are distributed along the length direction X, which simplifies the manufacturing process, helps to reduce manufacturing cost, improves production efficiency, and makes the light guide body 10 more easily integrated and installed.
[0058] In one of the embodiments, in combination with Figure 5 and Figure 6 , the light guide cross section 210 includes a first connecting plane 241 and a second connecting plane 242, and the first connecting plane 241, the reflection curved surface 220, the second connecting plane 242 and the light-out curved surface 230 are sequentially connected end to end. The reflection curved surface 220 and the light-out curved surface 230 are connected by planes, which simplifies the optical design and reduces the design difficulty and manufacturing difficulty.
[0059] In one of the embodiments, in combination with Figure 4 and Figure 5 , the projection of the light-out curved surface 230 on the thickness direction Z covers the projections of the reflection curved surface 220, the first connecting plane 241 and the second connecting plane 242 on the thickness direction Z, that is, the light reflected by the reflection curved surface 220, the first connecting plane 241 (if any) and the second connecting plane 242 (if any) can be effectively received and emitted by the light-out curved surface 230, which ensures that the light inside the light guide body 10 is used to the maximum extent and reduces light loss.
[0060] In one of the embodiments, in combination with Figure 4 and Figure 5 , the first connecting plane 241 and the second connecting plane 242 are located on the same horizontal plane and are distributed along the width direction Y. The first connecting plane 241 and the second connecting plane 242 are located on the same horizontal plane, which helps to improve the assembly stability of the light guide body 10.
[0061] In one of the embodiments, the light guide body 10 comprises a light mixing section 100 and a light output section 200 connected in sequence along the length direction X, the light output section 200 has a light guide cross section 210, the light mixing section 100 has an incident surface 101 at the end away from the light output section 200, and the remaining side surface of the light mixing section 100 is used to guide the light to the reflection curved surface 220, ensuring that the light can propagate along the predetermined path inside the light guide body 10, and then the reflection curved surface 220 reflects the light to the light output curved surface 230, achieving effective control of the light path. The area of the remaining side surface of the light mixing section 100 is large, which wraps the incident surface 101, so that all the incident light is basically guided to the reflection curved surface 220, improving the utilization rate of the light.
[0062] In some embodiments, in combination with Figure 1 , the incident surface 101 is a plane, which simplifies the light introduction, reduces the scattering and reflection of the light, and enables more light to be effectively guided into the light guide body 10.
[0063] In some embodiments, in the projection along the length direction X, the projection of the incident surface 101 is located within the projection of the light guide cross section 210, reducing the deviation and scattering of the light at the entrance, and ensuring that the light can propagate along the predetermined path inside the light guide body 10.
[0064] In one of the embodiments, the outer diameter of the light mixing section 100 is less than or equal to the outer diameter of the light output section 200, and the outer diameter of the light mixing section 100 gradually increases along the direction close to the light output section 200, which can more effectively capture and collect the light from the incident surface 101 and guide it to the reflection curved surface 220, improving the light collection efficiency. The gradual increase of the outer diameter helps to reduce the loss of light during transmission. With the increase of the cross-sectional area, the number of reflections and the degree of scattering of the light inside the light guide body 10 are reduced, thereby reducing the attenuation of the light.
[0065] Embodiment two
[0066] In combination with Figure 3 , the present application provides an automobile atmosphere lamp, which comprises a lamp bead 20 and the light guide body 10 of any one of the above embodiments, and the lamp bead 20 is arranged at one end of the light guide body 10 having the incident surface 101.
[0067] The light emitted by the lamp bead 20 is incident into the inside of the light guide body 10 through the light inlet surface 101, is dispersed and expanded to enlarge the irradiation area by the reflection curved surface 220, and is further dispersed and emitted by the light outlet curved surface 230, so that the light is no longer limited to a small emission area by the double dispersion mechanism, and a wider irradiation area is achieved. The reflection curved surface 220 has a large surface area compared with a plane, and is beneficial to reflecting the light in all directions. The light outlet curved surface 230 wraps the reflection curved surface 220, can receive the reflected light from all directions, and further expands the emission area. In addition, the emitted light is more uniform due to the multiple dispersion of the light on the reflection curved surface 220 and the light outlet curved surface 230.
[0068] In one embodiment, the automobile atmosphere lamp further comprises a light homogenizing plate located on the side of the light guide body 10 away from the reflection curved surface 220, to uniformly emit the light emitted by the light outlet curved surface 230. The light homogenizing plate can further eliminate the non-uniformity of the light, and ensure that the light is more uniformly distributed in the entire irradiation area. The light homogenizing plate can reduce bright spots and dark spots in the light, thereby effectively reducing the generation of glare and improving the comfort and safety of the driver.
[0069] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
