Description
Technical Field
[0001] The utility model belongs to the field of lighting, and particularly relates to a high beam lens module and an automotive high beam lamp. Background Art
[0002] A high beam lens is an optical element applied to an automotive high beam lamp system, mainly used for refracting and focusing the light emitted by a light source to achieve a better lighting effect.
[0003] The existing high beam lens can only conduct parallel guiding on the light generated by the light source, making the projected light too focused and without gradient. This will not only cause strong interference to oncoming vehicles, but also the overly focused light has a limited illumination range, which is not conducive to the driver's recognition of the road conditions. Summary of the Utility Model
[0004] The purpose of the embodiment of the utility model is to provide a high beam lens module and an automotive high beam lamp, aiming to solve the problem that the light projected by the existing automotive high beam lamp is too focused.
[0005] The embodiment of the utility model is implemented as follows. A high beam lens module is provided, and the high beam lens module includes:
[0006] A light source;
[0007] A first lens disposed behind the light source;
[0008] A second lens located behind the exit surface of the first lens. A light deflection structure is provided on the second lens. After the light emitted by the light source is refracted by the first lens, a part of the light falls on the entrance surface of the second lens and exits from the exit surface of the second lens, and another part of the light falls on the light deflection structure and exits from the exit surface of the second lens, causing the optical paths of the two parts of light to deviate, so as to form a brightness gradient in the light projection area.
[0009] Preferably, the entrance surface of the second lens is bent to form a bending line, dividing the second lens into two half lenses;
[0010] The light deflection structure is an arc-shaped groove provided on the entrance surface of the second lens. The arc-shaped groove passes through the bending line, and the bending line divides the arc-shaped groove into two half grooves, and each half groove is located on the entrance surface of a half lens.
[0011] Preferably, there are two light sources and two first lenses; each light source corresponds to a first lens and a half lens. The light generated by the light source is projected onto the corresponding half lens through the corresponding first lens. The shape of the first lens enables a part of the light of the light source to irradiate the half groove of the corresponding half lens, and another part of the light to irradiate the entrance surface of the corresponding half lens.
[0012] Preferably, it further includes a mounting plate; two light sources are spacedly mounted on the mounting plate, and the first lens corresponding to each light source is obliquely mounted on the mounting plate, and the light source is located in front of the incident surface of the first lens.
[0013] Preferably, when the light rays of each light source are projected onto the corresponding half-lens, the light rays incident through the semi-groove are divergently emitted from the exit surface of the second lens; the light rays incident through the incident surface outside the semi-groove are convergently emitted from the exit surface of the second lens.
[0014] Preferably, the converged light rays of the half-lens are projected into a central region on the projection surface, and the diverged light rays of the half-lens are projected into an edge region on the projection surface; the central region and the edge region are rectangular; there are 2 edge regions, which are respectively connected to the two short sides of the central region.
[0015] Preferably, in each half-lens, the area inside the semi-groove is smaller than the area of the incident surface outside the semi-groove, and the amount of converged light rays is greater than the amount of diverged light rays, so that the light intensity in the central region is greater than the light intensity in the edge region, thereby forming a brightness gradient.
[0016] Another aspect of the embodiment of the present invention provides a high beam headlight for an automobile, and the high beam headlight for an automobile includes:
[0017] a lamp housing; and
[0018] a high beam headlight lens module mounted in the lamp housing.
[0019] A high beam headlight lens module provided by an embodiment of the present invention includes a light source; a first lens disposed behind the light source; a second lens located behind the exit surface of the first lens, and a light ray deflection structure is provided on the second lens. After the light rays emitted by the light source are refracted by the first lens, a part of the light rays fall on the incident surface of the second lens and are emitted from the exit surface of the second lens, and another part of the light rays fall on the light ray deflection structure and are emitted from the exit surface of the second lens, so that the optical paths of the two parts of the light rays deviate, thereby forming a brightness gradient in the light projection area; in this embodiment, by providing a light ray deflection structure on the second lens, a part of the light rays of the light source can be divergently emitted, and another part of the light rays can be convergently emitted, thereby forming a brightness gradient in the projection area, thus avoiding the over-concentration of light rays, reducing the impact on oncoming vehicles, and due to the deviation of the light rays, improving the divergence of the light rays, increasing the overall projection area, and being more conducive to the driver to identify the road conditions and ensuring driving safety.

[0027] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0028] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.
[0029] As Figure 1 - Figure 2 shown, a high beam lens module provided by an embodiment of the present invention, the high beam lens module includes:
[0030] Light source 1;
[0031] The first lens 2, arranged behind the light source 1;
[0032] The second lens 3, located behind the exit surface of the first lens 2, a light ray deflection structure 33 is provided on the second lens 3, after the light rays emitted by the light source 1 are refracted by the first lens 2, a part of the light rays fall on the incident surface of the second lens 3 and are emitted from the exit surface of the second lens 3, and another part of the light rays fall on the light ray deflection structure 33 and are emitted from the exit surface of the second lens 3, so that the paths of the two parts of light rays deviate, thereby forming a brightness gradient in the light projection area.
[0033] In this embodiment, the light source 1 can be an LED lamp, a xenon lamp, or other types of light sources 1; the light source 1 is disposed adjacent to the incident surface of the first lens 2, so that the first lens 2 can fully collect the light of the light source 1 and direct the light in a set direction. The first lens 2 and the second lens 3 are spaced apart, and the relative positions of the two lenses are such that the light directed by the first lens 2 all falls within the range of the incident surface of the second lens 3 and does not exceed the range of the second lens 3;
[0034] In the present application, by providing a light deflection structure 33 on the second lens 3, a part of the light of the light source 1 can be divergently emitted, and another part of the light can be convergently emitted, thereby forming a brightness gradient in the projection area, thus avoiding the over-concentration of light, reducing the impact on oncoming vehicles, and increasing the divergence of the light due to the deviation of the light, increasing the overall projection area, which is more conducive to the driver to identify the road conditions and ensure driving safety.
[0035] As Figure 3 shown, as a preferred embodiment, the incident surface of the second lens 3 is bent to form a bending line 31, so that the second lens 3 is divided into two half-lenses 32;
[0036] The light deflection structure 33 is an arc-shaped groove opened on the incident surface of the second lens 3. The arc-shaped groove passes through the bending line 31, and the bending line 31 divides the arc-shaped groove into two half-grooves 331, and each half-groove 331 is located on the incident surface of a half-lens 32.
[0037] There are two light sources 1 and two first lenses 2; each light source 1 corresponds to a first lens 2 and a half-lens 32. The light generated by the light source 1 is projected onto the corresponding half-lens 32 through the corresponding first lens 2. The shape of the first lens 2 is such that a part of the light of the light source 1 irradiates the half-groove 331 of the corresponding half-lens 32, and another part of the light irradiates the incident surface of the corresponding half-lens 32.
[0038] It further includes a mounting plate; the two light sources 1 are spaced apart and mounted on the mounting plate, and the first lens 2 corresponding to each light source 1 is inclined and mounted on the mounting plate, and the light source 1 is located in front of the incident surface of the first lens 2.
[0039] In this embodiment, the symmetry plane of the second lens 3 passes through the bending line 31, that is, the second lens 3 is divided into two connected half-lenses 32 by the symmetry plane passing through the bending line 31;
[0040] The spacing distance between the first lens 2 and the second lens 3 is a set distance (such as 10 cm); as Figure 4As shown, from the top-down perspective (the two first lenses are arranged side by side in the first direction, where the first direction is the extension direction of the line connecting the geometric centers of the two first lenses), the incident surface of the first lens 2 is concave, thus semi-surrounding the light source 1, and further enabling sufficient collection of the light emitted by the light source 1; the exit surface of the first lens 2 is a partially convex surface, that is, its convex position is biased towards the incident surface of the corresponding semi-lens 32 (since the semi-lens 32 is formed by being bent, the incident surface of the semi-lens 32 is correspondingly deflected), so that the light passing through the first lens 2 can be directed towards the direction of the incident surface of the corresponding semi-lens 32, and the thickness at each position of the first lens 2 is set such that the divergence degree of the light just enables the light to fall within the range of the incident surface of the corresponding semi-lens 32, and a part of the light falls into the semi-groove 331, that is, falls into the light deflection structure 33.
[0041] As a preferred embodiment, as Figure 5 shown, from the perspective along the first direction (since the two first lenses are arranged side by side in the first direction, only one first lens and the corresponding light source can be seen from this perspective, and Figure 5 the second lens in
[0042] is cut along the symmetric plane of the second lens passing through the fold line to present the deviation of the light path passing through the light deflection structure and the light path not passing through the light deflection structure), when the light of each light source 1 is projected onto the corresponding semi-lens 32, the light incident through the semi-groove 331 diverges and exits from the exit surface of the second lens 3; the light incident through the incident surface outside the semi-groove 331 converges and exits from the exit surface of the second lens 3.
[0043] After the converging light of the semi-lens 32 is collected, it is projected into a central region on the projection surface, and the diverging light of the semi-lens 32 is projected into an edge region on the projection surface; the central region and the edge region are rectangular; there are 2 edge regions, which are respectively connected to the two short sides of the central region.
[0044] In this embodiment, as Figure 6 shown, the long sides of the central region and the edge region of each semi-lens 32 are vertical, the short sides are horizontal, and the short sides of the edge region are connected to the short sides of the central region; the central regions formed by the two semi-lenses 32 are connected at the long sides, and the edge regions are also connected at the long sides, thereby merging the projection regions of the two semi-lenses 32 and ensuring the continuity of the projection regions.
[0045] A motor vehicle high beam lamp provided by an embodiment of the present utility model, the motor vehicle high beam lamp includes:
[0046] Lamp housing; and
[0047] The high beam lens module installed in the lamp housing.
[0048] In this embodiment, the high beam lens module in the automotive high beam lamp can make a part of the light rays of the light source 1 diverge and another part of the light rays converge by arranging a light deflection structure 33 on the second lens 3, thereby forming a brightness gradient in the projection area, avoiding the over-concentration of light rays, reducing the impact on oncoming vehicles, and improving the divergence of light rays due to the deviation of light rays, increasing the overall projection area, which is more conducive to the driver to identify the road conditions and ensure driving safety.
[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
