Description
Technical Field
The invention belongs to the technical field of automobile headlamp assemblies. And more particularly, to an automotive headlamp assembly integrating a high beam lighting device and a low beam lighting device with each other.
Background
In the field of automotive lighting technology, current lighting fixtures generally include high beam lighting and low beam lighting in order to achieve different lighting in different driving environments. The high beam has a wide irradiation range and a long irradiation distance, and can improve a wide visible region for a driver. However, it is also because of the problem of the wide irradiation range and the long irradiation distance that it may have a very adverse effect on the normal running of other vehicles. Therefore, a low beam structure having a small irradiation range and a small irradiation distance is introduced into the lighting device of the vehicle. Therefore, through the switching cooperation use between the high beam and the low beam, the vehicle can be ensured to normally run in the environment with poor lighting conditions.
At present, there is a high beam and low beam integrated automotive headlamp product, which is based on a single light source and is provided with a movable shade inside the automotive lamp, and the switching between high beam illumination and low beam illumination is carried out by controlling the movement of the shade. However, since some of the light emitted from the light source is blocked, light energy loss is caused to some extent, and the light energy utilization rate of the vehicle lamp is reduced.
In addition, in low beam lighting, the area where the light is blocked is projected by the projection lens, and an absolute dark area is formed above the cutoff line of the low beam lighting field, so that the mandatory standard cannot be satisfied. In order to achieve the standard of weak illumination above the cut-off line of the low beam illumination field, some micro-structure processing is usually performed on the projection lens, so that the purpose of projecting part of light to a relevant area is achieved, and therefore, high requirements are placed on the processing precision of the projection lens, and high design and manufacturing costs are brought.
Disclosure of Invention
The invention aims at: aiming at the problems that the light energy utilization rate is not high due to the fact that the switching between high beam illumination and low beam illumination is carried out in a light blocking mode in the existing high beam and low beam integrated automobile headlamp products; and the problem of great difficulty in car lamp processing and manufacturing is caused by carrying out micro-structure treatment on the projection lens, so that the novel high-beam and low-beam integrated car headlamp assembly is provided. The car lamp structure adopts the low beam lighting device and the high beam lighting device which are mutually independent, and the corresponding spectral reflector is introduced into the low beam lighting device, so that the light energy utilization rate of a car lamp light source can be improved, the design freedom degree of the car lamp is increased, the projection distribution of lighting rays can be flexibly controlled, and the requirements of low beam lighting can be met.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
the high beam and low beam integrated automobile headlamp assembly comprises a high beam lighting device and a low beam lighting device which are mutually independent, wherein the low beam lighting device comprises a low beam light source, a low beam reflecting cover matched with the low beam light source and a low beam projection lens; the low beam lighting device further comprises a light splitting reflector, wherein A, B, C optical surfaces are arranged on the light splitting reflector, the A optical surface is a light refraction incident surface, the B optical surface is a light combination surface formed by a reflection area and a refraction exit area, and the C optical surface is a light refraction exit surface; the light splitting reflector is positioned between the low beam light source and the low beam projection lens, the A-type optical surface of the light splitting reflector is positioned at one side of the low beam light source, the C-type optical surface is positioned at one side of the low beam projection lens, and the B-type optical surface is positioned at the upper side;
the light rays emitted by the low-beam light source comprise X, Y, Z three types according to different paths:
x-ray is emitted by a low beam light source, reflected by a low beam reflecting cover, emitted by a low beam projection lens and finally projected below a cut-off line in a low beam illumination field;
the Y-type light rays are emitted by the low beam light source, reflected by the low beam reflector, refracted by the A-type optical surface and enter the spectral reflector, reflected by the reflecting area of the B-type optical surface in the spectral reflector, refracted by the C-type optical surface and emitted by the low beam projection lens, and finally projected into the low beam illumination field;
the Z-type light is emitted by the low beam light source, reflected by the low beam reflector, refracted by the A-type optical surface and enters the spectral reflector, refracted by the refractive exit area of the B-type optical surface and exits the spectral reflector, and finally is projected above the cut-off line in the low beam illumination field through the low beam projection lens.
The scheme adopts a far-beam lighting device and a near-beam lighting device which are mutually independent, and designs the near-beam lighting device by utilizing the spectral reflector, and mainly utilizes three light paths of the near-beam lighting device. One is the main illumination area reflected by the reflector and projected directly under the cutoff line via the projection lens. The other two are, with a spectral reflector, light rays are projected to the main illumination area and the supplementary or secondary illumination area above the cutoff line. 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 requirements of high beam and low beam illumination can be met.
As a preferable mode of the spectral reflector, the reflection area of the B-type optical surface is an optical total reflection surface or a coated reflection surface, so that the light incident on the reflection area of the B-type optical surface is reflected by the reflection area of the B-type optical surface and refracted by the C-type optical surface to form the spectral reflector.
In the reflection area, the light is totally reflected, and no overflowed light exists, so that the path of the light is accurately controlled. The reflection area can lead the light rays incident on the reflection surface to be totally reflected through the relation between the refractive index and the incident angle. In addition, the light can be totally reflected by plating a reflecting film.
As a preferable mode of the spectral reflector, the refractive exit area of the B-type optical surface is a surface shape change area or an atomized surface area, so that the light incident on the refractive exit area of the B-type optical surface is directly refracted from the refractive exit area of the B-type optical surface and overflows the spectral reflector.
In the refractive exit region, the light is refracted out of the spectral reflector for a supplementary illumination area above the cutoff. The refractive exit region may be designed as a surface shape change region with respect to the reflective region by the relation of refractive index to angle of incidence, or as an atomized surface region, to refract light out of the spectral reflector.
As a preferable scheme of the spectral reflector, a semi-reflective and semi-transparent film is plated on the B-type optical surface; the part of light rays incident on the B-type optical surface is directly refracted and overflowed from the B-type optical surface to the spectral reflector; the other part of light is reflected by the B-type optical surface and is refracted by the C-type optical surface to form the spectral reflector.
In the scheme, partial light is reflected by arranging the semi-reflective and semi-transparent film on the B-type optical surface, and the other part of light is refracted out of the spectral reflector. And the energy ratio of the refracted or emergent light rays adopts a semi-reflective semi-transparent film with corresponding energy ratio specification according to the requirement of low beam illumination.
As the preferable scheme of the spectral reflector, the A-type optical surface and the B-type optical surface are intersected, and an intersecting line forms a contour line; the contour line is projected in the low beam illumination field by the low beam 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 A-type optical surface and the B-type optical surface are intersected, an intersection line forms a contour line, and a shading device is arranged at the A-type optical surface; the combined contour line formed by the contour line and the contour line of the shading device is matched with the cut-off line in the low beam lighting requirement of the car lamp through the shape of the low beam projection lens projected in the low beam lighting field.
The shading 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 shading 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 preferred embodiment of the low beam lighting device, the contour line of the spectral reflector is located within ±5mm from the focal plane of the low beam projection lens.
As a preferred embodiment of the low beam lighting device, the low beam projection lens is a non-axisymmetric lens.
As a preferable mode of the low beam lighting device, the low beam light source is an upward single side light source, and the low beam reflection cover is positioned above the low beam light source.
As the preferred scheme of head-light assembly, still including being used for installing the lighting device mounting bracket on former factory's mount, be provided with high beam lighting device mounting bracket and dipped beam lighting device mounting bracket on the lighting device mounting bracket, high beam lighting device and dipped beam lighting device set up respectively on its mounting bracket.
As a preferable mode of the headlamp assembly, a radiator is provided between the high beam lighting device and the low beam lighting device and the mounting frame thereof.
In summary, due to the adoption of the technical scheme, compared with the prior art, the invention has the beneficial effects that: the high beam lighting device and the low beam lighting device which are mutually independent are adopted, and the low beam lighting device is designed by utilizing the spectral reflector, so that the automobile headlamp assembly 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 requirements of high beam and low beam illumination 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 far-near light integrated automobile headlamp assembly, which comprises a far-light lighting device and a near-light lighting device which are independent from each other as shown in figures 1-3. As shown in fig. 15-18, the low beam lighting device comprises a low beam light source, a low beam reflector matched with the low beam light source and a low beam projection lens. As shown in fig. 18, the low beam lighting device further includes a spectral reflector made of a visible light transparent material. As shown in fig. 19-20, the spectral reflector is provided with three types of optical surfaces A, B, C, wherein the type a optical surface is a light refraction incident surface, the type B optical surface is a light combination surface formed by combining a reflection area and a refraction emergent surface, and the type C optical surface is a light refraction emergent surface. As shown in fig. 18, the spectral reflector is located between the low beam light source and the low beam projection lens, the a-type optical surface of the spectral reflector is located on the low beam light source side, the C-type optical surface is located on the low beam projection lens side, and the B-type optical surface is located on the upper side.
As shown in fig. 23, the light rays emitted by the low beam light source include three types X, Y, Z according to the different paths:
x-ray is emitted by a low beam light source, reflected by a low beam reflecting cover, emitted by a low beam projection lens and finally projected below a cut-off line in a low beam illumination field;
the Y-type light rays are emitted by the low beam light source, reflected by the low beam reflector, refracted by the A-type optical surface and enter the spectral reflector, reflected by the reflecting area of the B-type optical surface in the spectral reflector, refracted by the C-type optical surface and emitted by the low beam projection lens, and finally projected into the low beam illumination field;
the Z-type light is emitted by the low beam light source, reflected by the low beam reflector, refracted by the A-type optical surface and enters the spectral reflector, refracted by the refractive exit area of the B-type optical surface and exits the spectral reflector, and finally is projected above the cut-off line in the low beam illumination field through the low beam projection lens.
The present embodiment adopts a preferred scheme to realize the light combining surface. Specifically, as shown in fig. 19-20, the reflective area and the refractive exit area of the B-type optical surface are designed in different areas.
As shown in fig. 19-20, the reflection area of the B-type optical surface is an optical total reflection surface or a coated reflection surface, so that the light incident on the reflection area of the B-type optical surface is reflected by the reflection area of the B-type optical surface, refracted by the C-type optical surface, and finally projected to the low beam illumination field by the projection lens. For how to realize the optical total reflection surface, the embodiment is specifically based on the refractive index of the spectral reflector and realized by adjusting the angle between the reflection surface and the light.
As shown in fig. 19-20, the refractive exit area of the B-type optical surface is a surface shape change area or an atomized surface area corresponding to the reflective area, so that the incident angle of the light is different, and further, a part of the light incident into the spectral reflector does not satisfy the optical total reflection condition on the B-type optical surface, and further, the light incident onto the refractive exit area of the B-type optical surface is directly refracted from the refractive exit area of the B-type optical surface and overflows the spectral reflector, and finally, is projected to the low beam illumination field through the projection lens.
In the low beam lighting device of the present embodiment, the light path can be adjusted only by the led-in spectral reflector. 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. 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 2
In comparison with the embodiment 1 in which the reflection area and the refraction exit area of the B-type optical surface are designed in different areas, the embodiment realizes that the light is a combined surface with reflection and refraction exit functions by plating the B-type optical surface with a semi-reflection semi-transparent film.
As shown in fig. 21, a semi-reflective and semi-permeable film is plated on the B-type optical surface; the part of light rays incident on the B-type optical surface is directly refracted and overflowed from the B-type optical surface to the spectral reflector; the other part of light is reflected by the B-type optical surface and is refracted by the C-type optical surface to form the spectral reflector.
The refraction and emergent light energy ratio of the semi-reflective semi-transparent film in the embodiment adopts the semi-reflective semi-transparent film with corresponding energy ratio specification according to the low beam illumination requirement.
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.
19-20, the class A optical surface intersects the class B optical 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 shape of the contour line projected in the low beam illumination field via the low beam projection lens can be matched to the cut-off line in the low beam illumination requirement of the vehicle 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. 22, the optical surface of a type and the optical surface of B type intersect, and the intersection line forms a contour line, and the contour line is a straight line. And a shading device is arranged at the A-type optical surface, and the lower edge of the shading device is a transition connecting line of a straight line and 45 degrees. The combined contour line formed by the contour line and the contour line of the shading device is matched with the cut-off line in the low beam lighting requirement of the car lamp through the shape of the low beam projection lens projected in the low beam lighting field.
In addition, the upper edge of the shading device in this embodiment is flush with one side of the intersection contour line, so that the shading device does not extend upward, and thus the shading of the light guided above the cutoff line in embodiment 1 or 2, which serves as a supplemental lighting function, can be avoided.
Example 5

The contour line of the spectral reflector is located within + -5 mm from the focal plane of the low beam projection lens. The low beam projection lens is a non-axisymmetric lens. The low beam light source is an upward single-side light-emitting light source, and the low beam reflecting cover is positioned above the low beam light source. The light emitting area of the light source is located inside or below the reflective cover.
