Description
Technical Field
The invention relates to the technical field of car lamp illumination. In particular to a light splitting reflector applied to the low beam illumination of a car lamp, an optical device based on the light splitting reflector and a car headlamp assembly based on the light splitting reflector and the optical device.
Background
In the technical field of car light illumination, in order to meet different illumination conditions under different driving environments, current illumination lamps generally need to include high beam illumination and low beam illumination.
The main principle of the low beam lamp is that the light emitted by the light source is distributed again by the optical component. At present, a common practice is to provide a light blocking member on a light transmission path, so as to form a desired illumination pattern in an illumination area, that is, an illumination area having a desired cutoff line by blocking a part of light.
The above-described manner of blocking light can form a low beam illumination region having a cutoff line that meets illumination requirements. However, some of the light emitted from the light source is blocked, so that light energy loss is caused to a certain extent, and the light energy utilization rate of the vehicle lamp is reduced.
In addition, the area where the light is blocked forms an absolute dark space above the cutoff line of the low beam illumination field by the projection of the projection lens, and thus the forced standard cannot be satisfied. In order to achieve the standard of weak illumination above the cutoff line of the low beam illumination field, some micro-structure treatments are usually performed on the projection lens, so as to achieve the purpose of projecting part of light to a relevant area, which puts a high requirement on the processing precision of the projection lens.
Disclosure of Invention
The invention aims at: the structure is designed to replace the traditional car lamp, and aims at solving the problems that the existing car lamp low beam illumination technology is low in light energy utilization rate due to the fact that illumination distribution of an illumination area is controlled in a light blocking mode, and car lamp machining and manufacturing difficulty is high due to the fact that micro-structure processing is conducted on a projection lens. The light structure of the car light introduces a corresponding light splitting reflector, so that the light energy utilization rate of a light source of the car light can be improved, the design freedom of the car light is increased, the projection distribution of illumination light can be flexibly controlled, and the requirements of low-beam illumination can be met.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
a beam-splitting reflector for low beam illumination of a car lamp, wherein a light incidence surface, a light reflection surface and a light emergent surface are arranged on the beam-splitting reflector; the light is refracted by the light incident surface and enters the light splitting reflector, then the light is reflected by the light reflecting surface in the light splitting reflector, and finally the light is refracted by the light emergent surface to exit the light splitting reflector; the light is projected into the low beam illumination field after being emitted by the projection lens.
Compared with the traditional mode of controlling illumination distribution of an illumination area by blocking light, the scheme does not shade light, and all light can be effectively utilized, so that the light energy utilization rate is improved. Specifically, the light path is guided by the light splitting reflector, so that light can be projected to an illumination area below a cutoff line in a low beam illumination field for main illumination. And the light can be guided and projected to an illumination area above a cut-off line in a low beam illumination field for supplementary illumination, so that the need of carrying out micro structure treatment on a projection lens is eliminated, and the manufacturing and production difficulty of the car lamp is reduced. In general, the light path is adjusted through the beam splitter, so that corresponding problems caused by light blocking components and micro structures of the projection lens can be omitted, and the low beam lighting requirement can be met.
As the preferable scheme of the spectral reflector, the light incident surface is intersected with the light reflecting surface, and the intersection line forms a contour line; the contour line is projected in the low beam illumination field by the projection lens to match the cut-off line in the low beam illumination requirement of the vehicle lamp.
For the traditional car lamp structure, the cut-off line is formed by the outline of the shielding device, so that the light energy utilization efficiency is affected. The scheme does not set a shielding device, and the cut-off line is a contour line formed by the intersection line of the light incident surface and the light reflecting surface. The scheme does not provide additional mechanical devices, and has the advantages of stable product performance and durability.
As the preferable scheme of the spectral reflector, the light incident surface is intersected with the light reflecting surface, the intersection line forms a contour line, and a shielding device is arranged at the light incident surface; the combined contour line formed by the contour line and the contour line of the shielding device is matched with the cut-off line in the requirement of low beam illumination of the car lamp through the shape of the projection lens projected in the low beam illumination field.
The shielding device adopted by the scheme is different from a light blocking component adopted by a traditional car lamp. The conventional light blocking member, the light above the contour line thereof is entirely blocked. The shielding device of this embodiment is only present at the contour line for forming the cutoff line and does not extend up Shen Zhedang light.
As a preferable scheme of the spectral reflector, the light emergent surface is provided with a light first refraction area; the light emitted from the area is projected below the cutoff line in the low beam illumination field after being emitted by the projection lens.
The scheme is that the light is projected to the main illumination area by arranging the first light refraction area on the spectral reflector.
As a preferable scheme of the spectral reflector, a light second refraction area is arranged on the light emergent surface; the light emitted from the area is projected above the cutoff line in the low beam illumination field after being emitted by the projection lens.
The scheme is that the light ray is projected to the secondary illumination area by arranging the light ray second refraction area on the spectral reflector. And the light is projected above the cut-off line without carrying out tiny structural treatment on the projection lens, so that the manufacturing difficulty and the arrangement difficulty of the projection lens are reduced.
As a preferred embodiment of the spectral reflector, the light is totally reflected on the light reflecting surface in the spectral reflector; the light ray reflecting surface is an optical total reflecting surface or a coating reflecting surface.
The light reflection surface is designed to be a total reflection surface, and no overflowed light exists, so that the path of the light is accurately controlled. The light incident on the reflecting surface can be totally reflected by the relation between the refractive index and the incident angle. In addition, the light can be totally reflected by plating a reflecting film.
The low beam lighting optical device for the car lamp comprises a light source, a reflecting cover matched with the light source, a projection lens and the spectral reflector; the light source is arranged on the beam source side, the light emitting surface is arranged on the beam projecting lens side, and the light reflecting surface is arranged on the upper side;
the light emitted by the light source includes X, Y two types according to different paths:
the X-ray is emitted by a light source, reflected by a reflecting cover, emitted by a projection lens and finally projected to a main illumination area below a cut-off line in a low beam illumination field;
the Y-type light is emitted by the light source, reflected by the reflecting cover, refracted by the light incident surface and enters the spectral reflector, reflected by the light reflecting surface in the spectral reflector, refracted by the light emergent surface, emitted by the projection lens and finally projected into the low beam illumination field.
The scheme utilizes the spectral reflector to design a low beam lighting device, and mainly utilizes two light paths of the low beam lighting device. One is reflected by the reflective cover and projected directly through the projection lens to the primary illumination area. Alternatively, the spectral reflector may be used to project light into the primary illumination region and the supplemental or secondary illumination region above the cutoff line.
As a preferred embodiment of the optical device, the contour line of the spectral reflector is located within ±5mm from the focal plane of the projection lens.
As a preferred embodiment of the optical device, the projection lens is a non-axisymmetric lens.
An automobile headlamp assembly comprises the light source, the reflecting cover, the spectral reflector and the projection lens which are matched with each other.
In summary, due to the adoption of the technical scheme, compared with the prior art, the invention has the beneficial effects that: the invention is applied to the beam-splitting reflector for the low beam illumination of the car lamp, the optical device based on the beam-splitting reflector and the car headlamp assembly based on the beam-splitting reflector and the optical device, and has the advantages of high light energy utilization rate and low production and manufacturing difficulty. Specifically, compare in traditional mode through blocking light and controlling illumination area illuminance distribution, this scheme does not shelter from light, and all light can all obtain effective utilization to the light energy utilization ratio has been improved. The light path is guided by the light splitting reflector, so that light can be projected to an illumination area below a cut-off line in a low-beam illumination field for main illumination. In addition, the light can be guided and projected to an illumination area above a cut-off line in a low beam illumination field for supplementary illumination, so that the need of carrying out micro structure treatment on a projection lens is eliminated, and the manufacturing and production difficulty of the car lamp is reduced. In general, the light path is adjusted through the beam splitter, so that corresponding problems caused by light blocking components and micro structures of the projection lens can be omitted, and the low beam lighting requirement can be met.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Example 1
The embodiment discloses a light splitting reflector for low beam illumination of a car lamp, and the light splitting reflector is made of visible light transparent materials as shown in fig. 1-3. The light splitting reflector is provided with a light incident surface, a light reflecting surface and a light emergent surface; the light is refracted by the light incident surface and enters the light splitting reflector, then the light is reflected by the light reflecting surface in the light splitting reflector, and finally the light is refracted by the light emergent surface to exit the light splitting reflector; the light is projected into the low beam illumination field after being emitted by the projection lens.
Specifically, as shown in fig. 2, the light emitting surface is provided with a light first refraction area. As shown in fig. 3, the first refraction area of the light ray in this embodiment is a plane, the angle of which is determined by the incident light ray angle, the refractive index of the spectral reflector, and other factors, and the light ray P exiting from this area is projected below the cutoff line in the low beam illumination field after being emitted through the projection lens by controlling the angle. In fig. 3, the light ray P enters from the left side and exits from the right side.
Specifically, as shown in fig. 2, the light emitting surface is provided with a light second refraction area. As shown in fig. 3, the second refraction area of the light beam in this embodiment is a curved surface, the angle of which is determined by the angle of the incident light beam, the refractive index of the spectral reflector, and other factors, and the light beam Q emitted from the area is projected above the cut-off line in the low beam illumination field after being emitted through the projection lens by controlling the angle. In fig. 3, light Q enters from the left side and exits from the right side.
The spectral reflector controls the distribution of light by a combination of optical refraction and optical reflection to form a primary illumination region below the cutoff in low beam illumination requirements and a secondary or supplemental illumination region above the cutoff. The scheme of forming low beam illumination through the light blocking mode is replaced, and meanwhile the problems of low light energy utilization rate and high manufacturing difficulty of the traditional mode are avoided.
Example 2
Based on the embodiment 1, as shown in fig. 2-3, the embodiment performs an optimal design.
As shown in fig. 3, the light is totally reflected on the light reflecting surface in the spectral reflector. The light reflection surface is an optical total reflection surface, and the embodiment is specifically based on the refractive index of the spectral reflector and is realized by adjusting the angle between the spectral reflector and the light. Or the light reflecting surface adopts a coated reflecting surface so as to achieve the effect of total reflection and accurately control the light path.
As shown in fig. 2, the second refractive region of the light exit surface is abrupt with respect to the first refractive region. As shown in fig. 3, the angles of the light incident on the second refraction area and the first refraction area are different, so that the light has different refraction exit angles, and the purpose of controlling the light path is further achieved. Or the second refraction area is an atomization surface and also has different incidence and refraction angles so as to achieve the purpose that the angles of emergent rays of the second refraction area and the first refraction area are different.
Example 3
On the basis of example 1 or example 2, this example provides an embodiment of forming a cutoff line in a low beam lighting requirement of a vehicle lamp.
As shown in fig. 1-2, the light incident surface intersects the light reflecting surface, and the intersection line forms a contour line. The two ends of the contour line adopted in the embodiment are parallel, and the middle is a 45-degree transition connecting line. The contour line formed is projected in the low beam illumination field by the projection lens, and can be matched with the cut-off line in the low beam illumination requirement of the car lamp.
Example 4
On the basis of example 1 or example 2, this example provides another embodiment of forming a cutoff line in a low beam lighting requirement of a vehicle lamp.
As shown in fig. 4, the light incident surface and the light reflecting surface intersect, and the intersection line forms a contour line, and the contour line is a straight line. And a shielding device is arranged at the light incidence surface, and the lower edge line of the shielding device is a transition connecting line of a straight line and 45 degrees. The combined contour line formed by the intersection contour line and the contour line or the lower edge line of the shielding device is matched with the cut-off line in the requirement of low beam illumination of the car lamp through the shape of the projection lens projected in the low beam illumination field.
In addition, the upper edge of the shielding device in this embodiment is flush with one side of the intersection contour line, so that the shielding device does not extend upward, and thus the shielding of the light guided above the cutoff line in embodiment 2, which serves as a supplemental lighting function, can be avoided.
Example 5
The embodiment discloses a car light dipped beam lighting optical device, as shown in fig. 5-6, comprising a light source, a reflecting cover matched with the light source, a projection lens and the spectral reflector according to any one of embodiments 1-4; the light source is arranged on the beam source side, the light emitting surface is arranged on the beam projecting lens side, and the light reflecting surface is arranged on the upper side;
as shown in fig. 7, the light emitted by the light source includes two types X, Y according to different paths:
the X-ray is emitted by a light source, reflected by a reflecting cover, emitted by a projection lens and finally projected to a main illumination area below a cut-off line in a low beam illumination field;
the Y-type light is emitted by the light source, reflected by the reflecting cover, refracted by the light incident surface and enters the spectral reflector, reflected by the light reflecting surface in the spectral reflector, refracted by the light emergent surface, emitted by the projection lens and finally projected into the low beam illumination field.
As shown in fig. 7, the Y-type light rays include Y1-type light rays and Y2-type light rays according to the projected positions:
the Y1 light is refracted out of the spectral reflector by the first refraction area of the light on the light emergent surface, so that the light emergent from the area is projected below the cut-off line in the low beam illumination field after being emergent from the projection lens. The Y1 ray corresponds to the P ray in example 1.
The Y2 light is refracted out of the spectral reflector by the light second refraction area on the light emergent surface, so that the light emergent from the area is projected above the cut-off line in the low beam illumination field after being emergent from the projection lens. The Y2 ray corresponds to the Q ray in example 1.
The low beam illumination optical device of the present embodiment can adjust the light path only by the introduced spectral reflector, and by light reflection and refraction, the projection of light to the main illumination area below the cutoff line and the supplementary illumination area above the cutoff line are realized.
Of course, the light may be directly incident into the spectral reflector from the light source without being reflected by the reflecting cover, but the effect of the light is poor.
Example 6
On the basis of embodiment 5, the embodiment performs an optimal design, as shown in fig. 5-6, and specifically includes the following aspects.
The contour line of the spectral reflector is located within + -5 mm from the focal plane of the projection lens. The projection lens is a non-axisymmetric lens. The light source is a light source emitting light to the upper single side, and the reflecting cover is positioned above the light source. The light-emitting area of the light source is positioned in or below the reflecting cover; the upward deflection of light is avoided, thereby avoiding the influence on the view of the opposite vehicle.
Example 7
The embodiment discloses an automobile headlamp assembly, which comprises the mutually matched light source, the reflecting cover, the spectral reflector and the projection lens according to any one of embodiments 1-6.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
