Description

Optical module and car lamp
Technical Field
The invention relates to the technical field of automobile illumination, in particular to an optical module and a car lamp.
Background
The main requirements of the current market for the car lamp module are compact in size and high in efficiency, and the modeling requirements of various car lamps are adapted on the premise of ensuring good optical performance. The high beam and low beam integrated module is a car lamp module integrating the high beam and low beam functions together, meets the market demand of the car lamp module and is widely used.
However, because the high beam and low beam integrated module is more complex than the single functional module, there are some defects, such as large size and weight, and poor high beam and low beam combining effect.
The main current high beam and low beam integrated module scheme in the market is shown in fig. 1, and consists of a convex lens at the front part and a secondary optical system at the rear part. Since the high beam and the low beam need to be imaged at the lens focus simultaneously and the low beam cutoff shape needs to be maintained, the high and low beam systems are typically arranged one above the other and the high and low beams are split with sheet metal or plastic condenser boundaries. As shown in fig. 2 and 3, the high beam pattern and the low beam pattern thus generated do not interfere with each other, and a black gap is easily generated at the joint between the high beam and the low beam, thereby affecting the appearance of the driver. In a system for evaluating the safety of car lights according to the China New Car evaluation protocol (C-NCAP), the brightness of the high beam at a downward angle can be evaluated when the safety of the high beam is checked. Because the high beam light type in the traditional high beam and low beam integrated module can not be overlapped to the low beam region, the score is lower, and the driving safety is influenced.
Because the far light and the near light of the traditional far and near light module commonly use one focus, the positions of the far and near light sources are also very close, the heat dissipation structure design is not facilitated, and the heat attenuation phenomenon of the light sources is easy to generate.
Meanwhile, the traditional design scheme needs to consider the focal length of the front convex lens and the focal length of the rear optical system, so that the overall module is longer in front-back size and heavier in weight.

An optical module 100 according to the first aspect of the present invention, as shown in fig. 4, 5 and 6, includes:
a light source assembly 110 including a low beam light source 111 and a high beam light source 112 configured to provide a low beam illumination light beam 1111 and a high beam illumination light beam 1121, respectively;
a mirror assembly 120 comprising a low beam mirror 121 and a high beam mirror 122 configured to receive and reflect, respectively, the low beam 1111 and the high beam 1121;
an inner lens assembly 130 including a low beam inner lens 131 and a high beam inner lens 132 configured to converge a low beam illumination beam 1111 and a high beam illumination beam 1121, respectively, and output a first low beam illumination beam 1112 and a first high beam illumination beam 1122;
an outer lens 140 configured to receive the first low beam illumination beam 1112 and the first high beam illumination beam 1122 from the low beam inner lens 131 and the high beam inner lens 132 and to converge and output a second low beam illumination beam 1113 and a second high beam illumination beam 1123.
The low beam light beam generated by the low beam light source 111 is emitted to the low beam inner lens 131 through the low beam reflector 121, the low beam inner lens 131 converges the low beam light beam 1111 and outputs the first low beam light beam 1112, and then the first low beam light beam 1112 is converged by the outer lens 140 and converges and outputs the second low beam light beam 1113;
the far-beam illumination beam 1121 generated by the far-beam light source 112 is emitted onto the far-beam inner lens 132 via the far-beam reflector 122, the far-beam illumination beam 1121 is converged by the far-beam inner lens 132 and output a first far-beam illumination beam 1122, and then the first far-beam illumination beam 1122 is converged by the outer lens 140 and output a second far-beam illumination beam 1123;
that is, the low beam and the high beam are divided into two secondary optical systems, which are respectively composed of one secondary lens (i.e., the inner lens assembly 130 and the outer lens 140) and a reflecting mirror; the low beam inner lens 131 and the high beam inner lens 132 form respective focuses, the focuses are respectively converged at the respective reflector roots, and a cut-off line of the low beam is formed by a secondary optical system of the low beam, irrespective of the high beam system.
Because the high beam and the low beam system do not share a focus, the low beam is formed into a cut-off line by a self-reflecting mirror or a condenser, the high beam and the low beam systems are not mutually affected, the high beam can be designed into a complete beam without the cut-off line, and a bright-dark boundary is not generated when the high beam and the low beam are overlapped, so that the driving safety is greatly improved;
when the heat design is carried out, the far and near light systems are independent, the distance between the light sources is far, the heat design is simpler and more convenient, the cost is lower, and the light sources are not easy to generate light attenuation.
It is understood that the composite focus formed by the outer lens 140 and the low beam inner lens 131 is also the position of the low beam light source 111.
In one example of the present invention,
the low beam inner lens 131 has a first light incident surface 1311 and a first light emergent surface 1312, the first light incident surface 1311 has an arc curved surface structure with a plurality of protrusions, and the first light emergent surface 1312 has a planar structure; the curvature of the low beam inner lens controls the focusing in the second direction (left-right direction), so that there is a focus in the second direction (left-right direction), and there is no focus in the first direction (up-down direction), nor is there any focusing effect.
The far-beam inner lens 132 has a second light incident surface 1321 and a second light emergent surface 1322, the second light incident surface 1321 has a planar structure, and the second light emergent surface 1322 has a concave arc-shaped surface structure.
In one example of the present invention, the outer lens 140 has a third light incident surface 141 and a third light emergent surface 142, the third light incident surface 141 is a plane, and the third light emergent surface 142 is a convex arc-shaped curved surface;
that is, the outer lens 140 uses a cylindrical lens arranged at the front lens of the module to diffuse light in a first direction (up and down) and not diffuse and focus light in a second direction (left and right), wherein the first direction and the second direction are perpendicular to each other.
The third light emitting surface 142 of the outer lens 140 controls focusing in the first direction (up-down direction), so there is a focus in the first direction (up-down direction), and there is no focus in the second direction (left-right direction), nor is there a focusing effect.
In one example of the present invention, the outer lens 140 has a gradually-changed wall thickness structure in the up-down direction, and gradually decreases from the middle to the up-down sides, and the outer lens 140 has a uniform wall thickness structure in the left-right direction;
the outer lens 140 is close to a transparent member with equal wall thickness in the left-right direction, so the scheme optimizes the color problem on the light type, and the overall length of the whole module can be greatly shortened compared with the traditional scheme because the lens and the reflecting mirror are free of focuses.
It will be appreciated that in practice the low beam is the first direction (up-down direction) of the outer lens and the second direction (left-right direction) of the inner lens 131 of the low beam together form a focusing effect.
In one example of the present invention, the low beam inner lens 131 and the high beam inner lens 132 are disposed at a side of the outer lens 140 near the third light incident surface 141, and have no overlapping area in a projection in a horizontal direction perpendicular to the outer lens 140;
that is, the projections of the low beam inner lens 131 and the high beam inner lens 132 in the horizontal direction on the outer lens 140 do not overlap, so that the low beam illumination beam 1111 and the high beam illumination beam 1121 generated by the low beam light source 111 and the high beam light source 112 do not affect each other.
In one example of the present invention, the low beam inner lens 131 is horizontally spaced from the outer lens 140 by a greater horizontal distance than the high beam lens is horizontally spaced from the outer lens 140.
In one example of the present invention, the low beam light source 111 coincides with the focal position of the low beam inner lens 131, and the high beam light source 112 coincides with the focal position of the high beam inner lens 132.
In one example of the present invention, the low beam light source 111 and the high beam light source 112 are LED lamps.
By adopting the above technical scheme, the light source assembly 110 determines respective focuses of far and near light by the two-stage lenses of the far and near light, so that the far light can be a complete light type without a cut-off line, and the problem that a dark area exists in the far and near light connection of the far and near light integrated module is solved; the front lens is only responsible for up-down diffusion and is not limited by focal length, so that the whole module is shorter in size and lighter in weight; the optical efficiency is high, the module brightness is high, and the optical performance is strong; the heat dissipation design is facilitated, and the light source is not easy to generate light attenuation.
A vehicle lamp 200 according to the second aspect of the present invention includes:
a lens holder 210 having a beam cavity 211 penetrating through both ends;
an optical module 100 as described above;
wherein the outer lens 140 is disposed at one end of the beam cavity 211, the mirror assembly 120 is disposed at the other end of the beam cavity 211, and the inner lens assembly 130 is disposed in the beam cavity 211;
that is, the low beam and the high beam of the vehicle lamp 200 are respectively two secondary optical systems, and each secondary optical system is composed of a secondary lens (i.e., the inner lens assembly 130 and the outer lens 140) and a reflecting mirror; the low beam inner lens 131 and the high beam inner lens 132 form respective focuses, the focuses are respectively converged at the respective reflector roots, and a cut-off line of the low beam is formed by a secondary optical system of the low beam, irrespective of the high beam system.
Because the high beam and the low beam system do not share the focus, the low beam is formed into a cut-off line by the self-reflecting mirror or the condenser, so that the high beam and the low beam systems are not mutually affected, the high beam can be designed into a complete beam without the cut-off line, and the light and shade boundary is not generated when the high beam and the low beam are overlapped, thereby greatly improving the driving safety.
As shown in fig. 7 and 8, by adopting the above technical solution, the vehicle lamp 200 determines the respective focuses of the far and near light by the secondary lenses of the far and near light, so that the far light can be a complete light type without a cut-off line, and the problem that a dark area exists in the far and near light connection of the far and near light integrated module is solved; the front lens is only responsible for up-down diffusion and is not limited by focal length, so that the whole module is shorter in size and lighter in weight; the optical efficiency is high, the module brightness is high, and the optical performance is strong; the heat dissipation design is facilitated, and the light source is not easy to generate light attenuation.
In one example of the present invention, further comprising: the heat sink 220 is provided with a heat sink,
the lens holder 210 is fixedly connected to one end where the reflector assembly 120 is mounted, and the light source assembly 110 is disposed on the heat sink 220 and configured to dissipate heat from the light source assembly 110;
since the light source assembly 110 generates a large amount of heat when emitting the illumination beam, the heat generated by the light source assembly 110 can be effectively dissipated by providing the heat sink 220, and the light source assembly 110 is not easy to generate light attenuation.
It can be understood that the low beam inner lens 131, the high beam inner lens 132 and the outer lens 140 are fixed on the lens bracket 210 by welding, and the reflector assembly 120 (the low beam reflector 121, the high beam reflector 122), the light source 110 and the radiator 220 are fixedly connected together by fasteners, that is, a plurality of corresponding first positioning holes, second positioning holes and third positioning holes are respectively and sequentially arranged on the reflector assembly 120, the light source 110 and the radiator 220, and the fasteners sequentially penetrate through the first positioning holes, the second positioning holes and the third positioning holes; the heat sink 220 is also fixedly connected with the lens holder 210 by a fastener.
While the exemplary embodiments of the optical module 100 and the lamp 200 according to the present invention have been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made to the specific embodiments described above without departing from the spirit of the invention, and various technical features and structures of the present invention may be combined without departing from the scope of the invention, which is defined in the appended claims.
