Existing solutions require light from LEDs to pass through a series of devices before being emitted from the light-emitting surface to achieve a more uniform lighting effect.

[0003] In traditional projects, known solutions require a large number of LEDs, which are inefficient, increase the cost of LED raw materials, and also complicate circuit design and increase thermal risks. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to solve the technical problem of low light guiding efficiency of thick-walled parts in the prior art, the present invention provides a thick-walled part structure and a vehicle lamp with uniform lighting.

[0005] In a first aspect, the present application discloses a thick-walled component structure with uniform lighting.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a thick-walled component structure with uniform lighting, including a thick-walled component, on which a light input portion and a light output portion are provided; a light collating total reflection portion, the light collating total reflection portion is provided on the thick-walled component, the light collating total reflection portion totally reflects the incident light entering from the light input portion and emits it from the light output portion; the guide line of the light collating total reflection portion is a parabola, so as to organize the incident light entering from the light input portion into parallel light and emit it from the light output portion.

[0007] The thick-walled component structure with uniform lighting of the present invention has incident light entering from the light incident portion, and the incident light is rectified into parallel light by the light aligning total reflection portion and then emitted from the light emitting portion, thereby improving the uniformity and luminous range of the light emitted from the light emitting portion.

[0008] Furthermore, the light incident portion adopts a rotating focusing groove.

[0009] Furthermore, a direction-adjusting total reflection portion is provided on the thick-walled member, and the light incident from the light incident portion is incident on the direction-adjusting total reflection portion and is totally reflected by the direction-adjusting total reflection portion to the light-arranging total reflection portion.

[0010] Furthermore, the direction-adjusting total reflection portion includes a first total reflection surface and a second total reflection surface, the light-arranging total reflection portion includes a third total reflection surface and a fourth total reflection surface, and the incident light of the light input portion is reflected on the first total reflection surface, the second total reflection surface, the third total reflection surface and the fourth total reflection surface in sequence, and is emitted from the light output portion.

[0011] Furthermore, the thick-walled member includes a light incident plate and a light exit plate connected to each other, the first and second total reflection surfaces being disposed opposite each other on the light incident plate, and the third and fourth total reflection surfaces being disposed opposite each other on the light exit plate. A guide line formed at the intersection of the first and second total reflection surfaces is arc-shaped; the angle between the first and second total reflection surfaces is 80 to 100 degrees, and the angle with the incident light is 40 to 50 degrees.

[0012] Furthermore, the first total reflection surface and the second total reflection surface include a plurality of reflection segments arranged along their circumferences, and the diameters of the plurality of reflection segments are unequal or partially equal.

[0013] Furthermore, the guide line formed at the junction of the third total reflection surface and the fourth total reflection surface is a parabola.

[0014] Furthermore, the reverse extension lines of the light rays at the same height and incident on the third total reflection surface converge at a convergence point, and multiple convergence points at different heights are on the same convergence line; the angle between the third total reflection surface and the fourth total reflection surface is 80 to 100 degrees.

[0015] Furthermore, the light incident portion is arranged on a surface of the light incident plate away from the light output plate, and a fifth total reflection surface is provided on the light incident plate. The incident light enters from the light incident portion and hits the fifth total reflection surface, and then is reflected in sequence on the first total reflection surface, the second total reflection surface, the third total reflection surface and the fourth total reflection surface, and finally is emitted from the light output portion.

[0016] In a second aspect, the present application discloses a vehicle lamp.

[0017] The following technical solutions are adopted:

As a result, fewer LED light sources can be used, reducing costs and the heat risk caused by too many LED light sources;

[0024] 2. By setting up multiple reflective segments, the structure can be changed according to the actual application scenario while ensuring clear light, saving space as much as possible and increasing the versatility of the solution;

[0025] 3. The light input part adopts the setting of rotating focusing groove, which can make more light enter from the light input part, thereby increasing the uniformity and brightness of the light emitted from the light output part;

[0026] 4. By setting the reverse extension line of the light entering the third total reflection surface to converge at the convergence point of the third total reflection surface, breaking through the inherent application mode, the reverse extension line of the incident light is used to converge at the virtual focus. The light entering from the second total reflection surface in a convergent state can be organized into parallel light rays, thereby improving the uniformity of the light. The setting of the guide line of the second total reflection surface as an arc line can obtain more incident light, and then cooperate with the third total reflection surface to obtain higher brightness.

DETAILED DESCRIPTION

[0043] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0044] Example 1

[0045] In a first aspect, the present invention discloses a thick-walled structure with uniform lighting.

[0046] Reference Figures 1 to 2A thick-walled component structure with uniform lighting comprises a thick-walled component, wherein the thick-walled component comprises a light input plate 1 and a light output plate 2 connected to each other, wherein the light input plate 1 is provided with a light input portion 11, and the light output plate 2 is provided with a light output portion 23. A total reflection system is provided between the light input plate 1 and the light output plate 2, and the total reflection system comprises a direction-adjusting total reflection portion and a light-collimating total reflection portion. During operation, the incident light enters from the light input portion 11, and the incident light entering the light input portion 11 first hits the direction-adjusting total reflection portion, then is totally reflected to the light-collimating total reflection portion, and finally is emitted from the light output portion 23, thereby improving the uniformity of the light emitted from the light output portion 23 and increasing the luminous range.

[0047] Reference Figure 1 and Figure 3 The light input portion 11 adopts a rotating focusing groove, which can be the shape of two frustum grooves spliced ​​together, or it can be spherical, elliptical, etc., or it can be the shape of a Fresnel lens, so that more light can enter the light input plate 1, thereby improving the lighting effect of the light emitted by the light output portion 23.

[0048] The direction-adjusting total reflection portion includes a first total reflection surface 12 and a second total reflection surface 13, and the light-collimating total reflection portion includes a third total reflection surface 21 and a fourth total reflection surface 22. The first total reflection surface 12 and the second total reflection surface 13 are relatively inclinedly arranged on the light incident plate 1, and the third total reflection surface 21 and the fourth total reflection surface 22 are relatively inclinedly arranged on the light output plate 2. Light from the light incident portion 11 is sequentially reflected by the first total reflection surface 12, the second total reflection surface 13, the third total reflection surface 21, and the fourth total reflection surface 22, and is emitted from the light output portion 23. The provision of multiple total reflection surfaces can increase light mixing and improve the brightness and uniformity of the output light.

[0049] Reference Figure 4 The guide line formed at the intersection of the first total reflection surface 12 and the second total reflection surface 13 is an arc-shaped guide line. That is, the projection of the first total reflection surface 12 and the second total reflection surface 13 is an arc-shaped surface, so as to receive more incident light. The included angle with the incident light is 40 to 50 degrees, preferably 45 degrees.

[0050] Reference Figures 4 to 6The guide line formed at the intersection of the third total reflection surface 21 and the fourth total reflection surface 22 is a parabola. That is, the overall projection of the third total reflection surface 21 and the fourth total reflection surface 22 is a parabola, and the opening of the parabola is arranged away from the second total reflection surface 12. When the light reflected by the second total reflection surface 13 falls on the third total reflection surface 21, it is aligned into parallel light and reflected onto the fourth total reflection surface 22, and finally emitted from the light exit portion 23. The reverse extension lines of the light rays entering the third total reflection surface 21 at the same height converge at a convergence point 211, and the convergence points 211 at different heights ultimately fall on the same convergence line 212. Therefore, the principle of parabolic light reflection can be used to organize the light reflected from the second total reflection surface 13 into parallel light rays for emission, thereby improving the uniformity of the light and the lighting effect.

[0051] Reference Figure 7 and Figure 8 Light from the light-entering portion 11 is reflected by the first total reflection surface 12 and the second total reflection surface 13, then rotated 180 degrees and emitted in the opposite direction, thereby adjusting the direction of the incident light. The angle between the first total reflection surface 12 and the second total reflection surface 13 is 80 to 100 degrees, that is, the angle a in the figure, preferably 90 degrees. The angle between the third total reflection surface 21 and the fourth total reflection surface 22 is 80 to 100 degrees, that is, the angle a in the figure, preferably 90 degrees.

[0052] The light emitting portion 23 can be provided with leather grain or pattern, etc., and the LED light source provided is not limited in color and can be single color, such as red, white, yellow, etc., or a mixture of multiple colors. The thick wall part can be made of transparent material such as PMMA or PC.

[0053] In a second aspect, the present application discloses a vehicle lamp.

[0054] A vehicle lamp comprises the thick-walled component structure with uniform lighting.

[0055] Reference Figure 9 and Figure 10 There are multiple thick-walled parts arrayed along the thickness direction of the light incident plate 1, and the light incident plates 1 of adjacent thick-walled parts abut against each other, so that multiple light-emitting portions 23 are arranged in an array along the thickness direction of the light incident plate 1, and adjacent light-emitting portions 23 abut against each other, thereby making the light-emitting range larger.

[0056] Example 2

[0057] Reference Figure 11 The difference from the first embodiment is that the first total reflection surface 12 and the second total reflection surface 13 include a plurality of reflection segments 131 arranged along their own circumferences. The diameters of the various reflection segments 131 may be unequal or partially equal. The specific settings can be set according to the installation space to save installation space as much as possible and improve the versatility of the overall solution.

[0058] Example 3

[0059] Reference Figure 12 , which differs from Example 1 in that light entrance portion 11 is disposed on the side of light entrance plate 1 away from light exit plate 2, and light entrance plate 1 is provided with a fifth total reflection surface 14. Incident light enters through light entrance portion 11 and strikes fifth total reflection surface 14, then sequentially reflects off first total reflection surface 12, second total reflection surface 13, third total reflection surface 21, and fourth total reflection surface 22, ultimately exiting through light exit portion 23. The addition of fifth total reflection surface 14 not only changes the direction of incident light to accommodate different installation scenarios, but also further improves light uniformity.

[0060] Example 4

[0061] Reference Figure 13 The difference from the first embodiment lies in that multiple thick-walled members are arranged in an array along the thickness direction of the light incident plate 1, and the thick-walled light incident plate 1 abuts the light exit plate 2 of the adjacent thick-walled member structure, so that the multiple light exit portions 23 are arranged in an array along the thickness direction of the light incident plate 1. The lengths of the multiple light exit portions 23 can gradually decrease along the thickness direction of the light incident plate 1 to create a gradient lighting effect. The lengths of the multiple light exit portions 23 can also vary, depending on the desired lighting effect.

[0062] Example 5

[0063] Reference Figure 14 The difference from the first embodiment is that two thick-walled parts are provided opposite to each other along the thickness direction of the light incident plate 1, and the light output plates 2 of the two thick-walled parts are abutted against each other and fixedly connected to improve the luminous range and brightness.

[0064] The above are some application examples. In practice, thick-walled components can be combined to suit the desired output pattern. The light-inlet and light-outlet panels can be cut to fit the installation space, retaining only the center portion to achieve the desired effect.

[0065] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
