A low beam primary lens or a high beam primary lens is provided with a concave structure at a structure of the primary optical lens near the condensing portion.
(1) The primary lens assembly is a single low beam primary lens.
The lamp module system includes a single low beam primary lens, a low beam collimator, a low beam light source, and a projection lens, the single low beam primary lens being disposed above a lens optical axis of the projection lens.
There are two situations for low beam primary lenses: a. a single primary lens for striking a low beam base pattern; b. the single primary lens of the low beam cutoff light type has a cutoff line structure below the low beam primary lens, and the cutoff line structure is arranged concave upwards.
(2) The primary lens assembly is a single high beam primary lens.
The lamp module system includes a single high beam primary lens, a high beam collimator, a high beam source, and a projection lens, the single high beam primary lens being disposed below a lens optical axis of the projection lens.
(3) The primary lens assembly is a low beam primary lens + a high beam primary lens.
Two main categories are known: ① The low beam primary lens and the high beam primary lens are matched up and down for use; ② The low beam primary lens and the high beam primary lens are used together.
① The low beam primary lens and the high beam primary lens are matched up and down for use:
The structure department that is close to spotlight part of primary lens is provided with a concave structure, and concave structure is in order to make concave structure optical adjustment face can realize the effect of adjusting luminance, makes the light angle and the width of reemitting from concave structure's optical adjustment face through concave structure's design can adjust, more easily satisfies car light regulation requirement, and concave structure's optical adjustment face can have the radian, more easily adjusts the width and the angle of light type, no matter width and angle's adjustment all include upper and lower and left and right directions. The deeper the concave structure is concave, the better.
The upper and lower fitting of the low beam primary lens and the high beam primary lens comprises: a. the low beam primary lens arranged above comprises a concave structure, and the high beam primary lens arranged below comprises a concave structure; b. the low beam primary lens arranged above comprises a concave structure, and the high beam primary lens arranged below does not comprise the concave structure. Wherein, there are two kinds of cases in the primary lens of passing light: a primary lens for striking a low beam base light pattern and a primary lens for striking a low beam cut-off light pattern.
The overall combination form comprises the following four types:
a. The upper part is a primary lens for striking a low beam base light type comprising a concave structure, and the lower part is a high beam primary lens comprising a concave structure, wherein both lenses do not need to be structured for striking a cut-off line;
b. The upper part is a primary lens of a light cut-off line type of the light with a concave structure, the lower part is a high beam primary lens of the light with a concave structure, wherein both lenses are required to have structures for cutting off lines, the cut-off line structure of the primary lens of the light cut-off line type of the light is positioned below the lens, the cut-off line is arranged to be concave upwards, the cut-off line structure of the high beam primary lens is positioned above the lens, and the cut-off line is arranged to be convex upwards;
c. the upper part is a primary lens for striking a low beam base light type comprising a concave structure, and the lower part is a high beam primary lens not comprising a concave structure, wherein both lenses do not need to be structured for striking a cut-off line;
d. The upper side is the primary lens of the light type of beating the low beam cut-off line that includes the concave structure, and the below is the high beam primary lens that does not include the concave structure, and wherein two lenses all need to have the structure of doing for beating out the cut-off line, and the cut-off line structure of the primary lens of beating the light cut-off line type is in the below of lens, and the cut-off line setting is upwards concave, and the cut-off line structure of high beam primary lens is in the top of lens, and the cut-off line setting is upwards protruding.
The high beam primary lens does not need a concave structure because the high beam rule itself has low requirements on the up-down angle and the left-right angle, and therefore, the concave structure is not needed.
When the high beam primary lens needs a cut-off line, the primary lens of the light type with the concave structure for making the high beam cut-off line above and the primary lens of the high beam below can be infinitely close, and the optimal approach is infinite, but the primary lens cannot be completely overlapped or made into one piece, and the complete overlapping or one piece can cause the cut-off line not to be made.
② The low beam primary lens and the high beam primary lens are matched up and down for use:
Left and right are a low beam primary lens and a high beam primary lens, respectively. There are two cases of low beam primary lenses, a primary lens that strikes a low beam base pattern and a primary lens that strikes a low beam cut-off pattern.
The low beam primary lens comprises a concave structure, and the high beam primary lens may or may not comprise a concave structure.
The left and right matching use belongs to the narrow opening on the whole appearance of a single module.
From a multiple module perspective, a plurality of modules is meant to include a plurality of individual modules as described above. For example, the plurality of modules include a module 1 (single low beam primary lens+low beam collimator+low beam light source+projection lens), a module 2 (single high beam primary lens+high beam collimator+high beam light source+projection lens), a module 3 (one module for use with low beam primary lens and high beam primary lens up and down), and a module 4 (one module for use with low beam primary lens and high beam primary lens left and right), and the combination is not limited.
The combination positions of a plurality of modules, the quantity and the mode of arranging are specifically set according to specific projects, whether the modules are arranged in a straight line or in an oblique line, are arranged up and down or are arranged left and right, and the modules in front of which are arranged at the back of which are arranged can be designed according to actual conditions of the projects. Even though the modules are arranged in a combined way, the modules are in a narrow opening shape seen from the appearance shape angle, and the narrow opening shape is a model pattern which is preferred and popular in the present and future by a host factory and a vehicle purchasing user.
The size of the single module of the embodiment is small, and a plurality of optical systems meeting the optical regulation requirements can be combined by the modules. Compared with the prior art that one module is adopted to realize all functions, the multiple small-size modules are more flexible in position arrangement and design scheme, the size of a single module is smaller, particularly the size of an opening, and the problem of space limitation can be solved for the gradually-narrowing car lamp space. The module of this embodiment is no matter singly or upper and lower combination, and the size all belongs to narrowly, and upper and lower combination module opening size can accomplish upper and lower 15mm, belongs to the small-size.
The projection lens of the module of this embodiment is thin. In order to meet the requirement of visual angle, the projection lens needs to be designed thicker, if the module lens is thin, the large visual angle cannot meet the requirement of optical regulations, but the embodiment realizes the optical effect and meets the requirement of visual angle of optical regulations by using a plurality of module combinations and flexible arrangement modes, and meets the visual angle by superposing a plurality of partition combinations, so that the projection lens of a single module can be thinner. The thinness of the projection lens of the single module reduces cost and, because of the lighter weight, the mounting means can be more varied, such as riveting, eliminating the need for snaps or screws.
The optical primary lens-to-projection lens distance of the present embodiment becomes smaller. The outer surface of the projection lens is preferably gentle, at this time, the curvature of the inner surface of the projection lens can be made larger, so that the distance between the focus and the projection lens is reduced, the focal length is shortened, the design of the cut-off line structure of the module system can be closer to the lens direction, the design of the cut-off line structure of the embodiment is arranged at the front end of the optical primary lens, the distance from the optical primary lens to the projection lens is reduced, and further the module depth space is small, the design is more flexible, and the space limitation is small.
The lenses of each module may be arranged differently. For example, the light exit surface of the lens for realizing the low beam base light type function is designed to have a smaller curvature, the light entrance surface is preferably designed to be concave (which is defined as concave when viewed from the outside sunlight direction), and the module has no sunlight focusing problem because sunlight is incident on the lens surface and diverged and then emitted, and the sunlight focusing problem can be avoided by light divergence, so that sunlight is incident on the inner surface of the lens and no focusing problem exists. The outer surface of the lens for realizing the low beam cutoff function is designed to be gentle, and the inner surface is preferably designed to be convex (defined as convex from the outside sunlight direction view), and the unit has a sunlight focusing problem. In the prior art, a module, namely a lens, is adopted, the design of the lens is that the outer surface is concave (the concave is defined as concave from the view angle of the outside sunlight direction), the inner surface is gentle, and the sunlight irradiates the lens and is easy to be focused, so that the problem of sunlight focusing exists wholly.
Compared with the prior art, the module of the embodiment can effectively avoid sunlight focusing by the lenses of the low beam base light type, even though the lenses of the low beam cut-off line still have the possibility of sunlight focusing, the possibility of sunlight focusing problem is reduced, and compared with the design scheme of one lens in the prior art, the application adopts the combination form of a plurality of module units, so that the design adjustment and change space is larger and more flexible. In this embodiment, the lens for driving the light beam cutoff and the lens for driving the light beam base light can use a plurality of combinations, and can be configured such that the brightness values of the light sources are different, and the brightness of the light sources can be adjusted according to different design requirements.
Along with individuation of car light function, the use of dynamic effect and high energy light source is more frequent, and car light space is more narrow in addition, and the heat problem is more serious and difficult to solve, prior art often only can add fan, radiator to accelerate the heat dissipation, but can not thoroughly solve the heat problem of car light, if adopt a plurality of fans and radiator, can increase the manufacturing cost of car light again. The embodiment uses at least one module unit to realize modeling and car light regulation requirements, the cut-off line position of a single module unit can be arranged towards the direction close to a projection lens, the cut-off line of each module unit, especially the lens unit for cutting off the light cut-off line, can be closer to the projection lens, namely the lens for cutting off the light cut-off line and the lens for cutting off the light basic light type can be differently arranged on the length, so that the light source position of the lens unit for cutting off the light cut-off line is arranged on different planes in a separated mode than the light source position of the lens unit for cutting off the light basic light type, heat concentration can be avoided, and heat dissipation is more facilitated.
