It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example one
The present embodiment relates to a light guide for a vehicle lamp, which is designed to overcome the disadvantages of the conventional high-beam and low-beam function installation method.
Specifically, referring to fig. 1 to 3, the light guide of the present embodiment includes a body 1 made of a transparent material, the body 1 is in a strip shape, and a first optical input end 2, a second optical input surface 3, a second optical output surface 4 and a light guide hole 5 are configured on the body 1.
As a general transparent material for the body 1, for example, one of PMMA (acrylic resin), PC (polycarbonate) or ABS (acrylonitrile butadiene styrene) can be used. Of course, besides the above materials, other transparent materials that can be used for manufacturing the light guide medium in the field may be adopted according to design requirements, and the present invention is not limited thereto.
In the present embodiment, as a preferred embodiment, the cross section of the strip-shaped body 1 orthogonal to the length direction thereof is rectangular, so that the light guide body of the present embodiment has three dimensions of length, width and height, like the light guide strip already applied in the art. In the present embodiment, the light guide itself should be understood in the longitudinal direction, the width direction, and the height direction as shown in fig. 1. At the same time, it should be noted that, in addition to the rectangular shape described above, it is of course possible to make the cross section of the body 1 square or other different shapes based on the design. Regardless of the shape of the cross-section of the main body 1, the length, width and height of the main body 1 can be designed according to the actual appearance and lighting requirements while satisfying the functions of the light guide of the present embodiment.
Still referring to fig. 1, the first optical input 2 is located at one end of the body 1, and in conjunction with fig. 5 or 6 to be mentioned below, the side surface 201 at this first optical input 2 is formed to be introduced into the body at a location located at the other end of the body
The light incident surface of the light emitted from the light source at the first optical input end 2 is configured such that at least a portion of the light emitted from the light source at the first optical input end 2 can be quasi-collimated and transmitted in the body 1.
It should be noted that the quasi-collimated propagation has a non-zero divergence smaller than a certain angle, and the specific angle limit is also selected according to the actual design so as to satisfy the optical function. In addition, the first optical input end 2 for realizing light-like collimation and propagation as described in this embodiment has been widely applied to the optical structure of the vehicle lamp with the existing lens structure, so that the first optical input end 2 may be obtained by considering the existing related art, and details thereof will not be repeated herein.
The second optical input surface 3 is located on one side of the body 1 and is a plane extending along the length direction of the body 1, the second optical output surface 4 is located on the other side of the body 1 opposite to the first optical input surface 3, meanwhile, the second optical output surface 4 is also a plane extending along the length direction of the body 1, and the second optical output surface 4 is also parallel to the first optical input surface 3. Wherein the second optical input surface 3 is formed at a light entrance surface for introducing external light from other light sources, and the second optical output surface 4 serves as a common light output surface for light entering through the first optical input end 2 and the second optical input surface 3.
The light guide holes 5 of this embodiment are specifically a plurality of light guide holes arranged at intervals along the length direction of the body 1, and the light guide holes 5 are arranged in a line shape as shown in fig. 1 and fig. 2, and each light guide hole 5 is a narrow rectangular hole which is completely or partially arranged in a penetrating manner along the height direction of the body 1, and the light guide holes 5 in the rectangular shape are all parallel to each other. In the present embodiment, it is described that each light guide hole 5 preferably completely penetrates the main body 1, and the width k of each narrow rectangular light guide hole 5 may be generally between 0.01mm and 5mm, and may be, for example, 0.01mm, 0.02mm, 0.05mm, 0.1mm, 0.5mm, 1.0mm, 1.5mm, or 2mm, 2.5mm, 3mm, 4mm, 5 mm.
In addition, in addition to the above limitation of the width k, the length of the rectangular light guide hole 5 is not limited in this embodiment, and may be selected according to the overall structure size and the optical function requirement in the specific design. As shown in fig. 5, in the overall structure of the light guide, the light guide holes 5 arranged in a line are offset toward the second optical input surface 3 side compared to the first optical input end 2, and the arrangement of the included angle α between the light guide holes 5 and the planar second optical input surface 3 makes the incident inclination angle of the quasi-collimated propagating light entering from the first optical input end 2 at the position of each light guide hole 5 larger than the total reflection critical angle, so as to form the total reflection of the quasi-collimated propagating light toward the second light output surface 4.
It should be noted that, for the specific value of the included angle α, a technician may select the relative position between the first optical input end 2 and each light guide hole 5 by laying, which only needs to satisfy that the incident inclination angle of the light rays of the quasi-collimation propagation in the body 1 at the position of the light guide hole 5 is greater than the total reflection critical angle.
It should be noted that, in addition to the light guide holes 5 being arranged in a straight line, in the present embodiment, as shown in fig. 4, the light guide holes 5 are parallel to each other, and the light guide holes 5 are also arranged alternately left and right along the length direction of the main body 1 of the light guide body. At this time, the other structural configurations of the light guide hole 5 are the same as those described above, and it is also possible to make the incident inclination angle of the quasi-collimated and propagated light in the body 1 at the position of the light guide hole 5 larger than the total reflection critical angle.
In this embodiment, in order to ensure the reflection effect of the light guide hole 5 on the quasi-collimated propagating light, at least two inner surfaces parallel to the length direction, that is, two opposite inner surfaces a, may be preferably polished. The specific application of the light guide of the present embodiment will be explained in the following second embodiment.
Example two
The present embodiment relates to a vehicle lamp structure, as shown in fig. 5 and 6, which integrally includes a light guide body as described in the first embodiment, a first operating light source 6 provided at a first optical input end 2 of the light guide body, and a second operating light source 7 located on an outer side of the light guide body with respect to a first optical input surface 3.
The first operating light source 6 is also the light source at the first optical input end 2 as described in the first embodiment, and the first operating light source 6 forms quasi-collimated propagating light rays in the body 1 by reflection of the side surface 201. In the embodiment, the second working light source 7 and the light guide are disposed in the opposite position, as shown in the figure, so that the incident inclination angle of the light emitted by the second working light source 7 at the position of the first optical input surface 3 is smaller than the total reflection critical angle, and meanwhile, the incident inclination angle of the light emitted by the second working light source 7 entering from the first optical input surface 3 at the position of the light guide hole 5 is also smaller than the total reflection critical angle.
The condition that the incident inclination angle is smaller than the critical angle of total reflection here is satisfied, and it is only necessary to make the included angle between the incident direction of the second working light source 7 and the second optical input surface 3 within a certain range, and the range can be obtained by simple calculation or limited adjustment for those skilled in the art.
In this embodiment, the first working light source 6 may be one of a position light source, a daytime running light source and a turn light source, and the second working light source 7 may be one of a high beam light source module and a low beam light source module. In addition, the present embodiment is also specifically described with the first operating light source 6 as a position light/daytime running light source and the second operating light source 7 as a high-low beam light source module, and the first operating light source 6 is preferably an LED light source, and the second operating light source 7 may also be an optical module using an LED as a light emitting body.
When the vehicle lamp structure of the embodiment is used, as shown in fig. 5, when only the position light or the daytime running light of the vehicle is turned on, the generated quasi-collimated light is transmitted in the light guide body, and after encountering the light guide hole 5, the quasi-collimated light is totally reflected and emitted from the second optical output surface 4 because the incident inclination angle is greater than the total reflection critical angle, so as to form a light beam emitted to the front of the lamp. When far and near light is lighted simultaneously, because the incidence inclination is less than the critical angle of total reflection, unsatisfied total reflection condition, so far and near light is refraction propagation in the light guide, and no matter be light guide or light guide 5 itself, it is the flat board that is parallel to far and near light, therefore can not change the traffic direction of refraction light to this can make far and near light follow second optics output face 4 and jet out to lamps and lanterns the place ahead, can not change far and near light type distribution.
The lamp structure of this embodiment can be behind the daytime running light/position light with far and near light source through the application of light guide structure in embodiment one, also when hiding behind daytime running light/position light, avoids the low beam type to see through daytime running light or position light when, can take place great deflection, especially can lead to the problem that the glare above the cut-off line is too bright.
The vehicle lamp of the embodiment can directly hide the far and near lights to the back of the daytime running light/position light, so that the effect that the far and near lights are completely invisible when not lighted can be achieved. Meanwhile, by the arrangement of the lamp structure, when the low-beam part is independently lightened, the low-beam part is not visible from the upper part of the cut-off line, and when the far-beam part is lightened, the high-beam part cannot be seen directly due to over-lightening, so that the influence of the over-lightening is not considered.
The present embodiment further relates to a vehicle, in which the vehicle lamp structure is applied, and the advantages of the vehicle lamp structure applied are the same as those described above, and are not described herein again.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
