Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobiles, and more specifically to a low-beam lens module and a vehicle lamp. Background Art
[0002] With the advancement of lighting technology and the diversification of shapes, ultra-narrow and high-efficiency lens modules are becoming increasingly popular in the automotive market. In the current design, the light from the light source is first collected by the focusing inner lens or reflector to the focus, then a light pattern with a light cutoff line is formed through a shading baffle, and finally the light is projected out by an outer lens (projection module). This design requires at least three parts: a focusing inner lens / reflector, a shading baffle, and an outer lens. However, since the outer lens requires a certain focal length to ensure the brightness of the module and a sufficient size to collect light at the focus, the light efficiency will be significantly reduced when the size of the outer lens is reduced to 12mm or narrower. The optical system of this design form has low light efficiency, which severely limits the flexibility of the lens size and is not conducive to its application in the overall lamp. In addition, a shading baffle is used to block the low-beam light pattern. The shading baffle is prone to deformation and wear after long-term use, and there will be coloring at the light cutoff line.

[0047] The core of the present utility model lies in disclosing a low beam lens module to reduce the size of the low beam lens module while maintaining the light efficiency.
[0048] Another core of the present utility model lies in disclosing a vehicle headlamp including the above-mentioned low beam lens module.
[0049] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not limit the content of the utility model described in the claims in any way. In addition, all the contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the utility model described in the claims. It should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings. Without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.
[0050] Combined with Figures 3 - 12 , the low beam lens module disclosed by the present utility model includes an inner lens 100 and an outer lens 200. The inner lens 100 has a first light incident surface 110, a total reflection surface 120, and a first light-emitting surface 130. The first light incident surface 110 is used to receive the light emitted by the light-emitting component 300. The total reflection surface 120 is used to reflect the light incident from the first light incident surface 110 to the first light-emitting surface 130. The light emitted from the first light-emitting surface 130 forms a low beam light pattern. The first light-emitting surface 130 includes a widened light-emitting surface 131 and a brightness supplement surface 132. The widened light-emitting surface 131 is used to emit light to both ends of the low beam light pattern to ensure the widening of the low beam light pattern. The brightness supplement surfaces 132 are multiple and are symmetrically arranged on both sides of the widened light-emitting surface 131. The brightness supplement surface 132 is used to emit light to the middle position of the low beam light pattern to ensure the brightness at the center position of the low beam light pattern. The foci of the light rays emitted from the widened light-emitting surface 131 and the brightness supplement surface 132 are all on the first focal line. The straight line where the focus of the outer lens 200 is located is defined as the second focal line 201, and the first focal line coincides with the second focal line 201.
[0051] Combined withFigure 12 After the light is emitted from the light-emitting component 300, it enters the inner lens 100 through the first light-incident surface 110, is reflected by the total reflection surface 120, and finally exits through the first light-emitting surface 130. The light exiting through the first light-emitting surface 130 enters the outer lens 200 through the second light-incident surface and exits through the second light-emitting surface 210.
[0052] The outer lens 200 is a line-focusing lens, which only focuses in a single direction. If the focusing direction of the outer lens 200 is defined as up-and-down focusing, then the outer lens 200 does not perform horizontal focusing. Since the foci of the light rays exiting from the widened light-emitting surface 131 and the brightness supplement surface 132 are both on the first focal line, and the first focal line coincides with the second focal line 201, that is, the reverse extension lines of the light rays exiting from the widened light-emitting surface 131 and the brightness supplement surface 132 ( Figure 12 the dotted lines in) converge to form multiple foci that are all on the second focal line 201.
[0053] Combined with Figure 5 and Figure 11 , Figure 11 The arrows in show the main light-emitting directions of the widened light-emitting surface 131 and the brightness supplement surface 132. The widened light-emitting surface 131 is used to emit light to both sides to ensure the widening of the low-beam light pattern. The brightness supplement surfaces 132 are symmetrically arranged on both sides of the widened light-emitting surface 131 and are used to emit light to the middle position of the low-beam light pattern to ensure the brightness at the middle position of the light-emitting light pattern. The widened light-emitting surface 131 is arranged in the middle position of the brightness supplement surface 132, which can effectively reduce the occlusion of the light rays of the inner lens 100 by the boundary of the outer lens 200.
[0054] Combined with Figures 5 - 7 , both the widened light-emitting surface 131 and the brightness supplement surface 132 protrude in the direction of the outer lens 200, so that the light rays emitted from the inner lens 100 are completely converged within the focal line range of the outer lens 200 in the up-and-down direction, that is, the foci of the reverse extension lines of the light rays emitted from the inner lens 100 fall on the second focal line 201, ensuring that all the light rays of the inner lens 100 can pass through the outer lens 200 and exit, avoiding the light efficiency loss caused by the narrowing of the up-and-down dimension of the outer lens 200.
[0055] Compared with the prior art, the low-beam lens module disclosed by the present utility model effectively improves the light energy utilization efficiency when the up-and-down dimension of the light-emitting surface of the low-beam lens module is reduced by making the first focal line coincide with the second focal line 201 and dividing the first light-emitting surface 130 into the widened light-emitting surface 131 and the brightness supplement surface 132 responsible for the widening and central brightness of the low-beam light pattern respectively, while ensuring the low-beam lighting effect and light pattern.
[0056] Combined with Figure 4, in a specific embodiment, the total reflection surface 120 includes a plurality of first reflection surfaces 121 and two second reflection surfaces 122; each first reflection surface 121 corresponds to each brightness compensation surface 132 one by one and reflects light; the two second reflection surfaces 122 correspond to the widened light-emitting surface 131 and are used to reflect light to the widened light-emitting surface 131, and the two second reflection surfaces 122 are used to reflect light to the two ends of the low beam light pattern respectively to ensure the widening of the low beam light pattern.
[0057] Combined with Figure 11 , each first reflection surface 121 is arranged along the first axis, the two second reflection surfaces 122 are respectively arranged along the second axis and the third axis, and the angles between the second axis and the third axis and the first axis are both preset angles α (α can be 8°), and the second axis and the third axis do not coincide.
[0058] Exemplarily, compared with the two second reflection surfaces 122 deflecting a preset angle α in the direction away from each other, the two second reflection surfaces 122 deflecting a preset angle α in the direction close to each other can effectively reduce the occlusion of the light of the inner lens 100 by the boundary of the outer lens 200 and ensure the widening of the low beam light pattern.
[0059] The number of the brightness compensation surfaces 132 is not limited to the four shown in the figure.
[0060] In a specific embodiment disclosed by the present utility model, a cut-off line structure 150 is correspondingly arranged on each first reflection surface 121. The cut-off line structure 150 is used to destroy a part of the surface shape of the first reflection surface 121, and this part of the surface shape corresponds to the light pattern above the cut-off line in the whole low beam light pattern, and thus the cut-off line of the low beam light pattern can be formed. Specifically, combined with Figure 5 and Figure 8 , the cut-off line structure 150 is arranged in the root area of the first reflection surface 121, and the cut-off line structure 150 is blocked by the outer lens 200 on the inner lens 100 and is not visible on the appearance of the module, which can improve the aesthetics of the module. Exemplarily, the cut-off line structure 150 can be arranged at 0.4 mm above the focus of the first reflection surface 121.
[0061] The cut-off line structure 150 and the inner lens 100 can be an integral structure and are integrally formed. The cut-off line structure 150 can specifically be a block structure. By setting the cut-off line structure 150, the cut-off line light pattern can be directly formed without additionally setting a light-shielding baffle, avoiding the occurrence of deformation, wear and coloration of the cut-off line of the light-shielding baffle.
[0062] In the low beam regulations, there is a test point named 50L. This test point has an upper limit value, and the brightness cannot be too high to avoid dazzling the driver of oncoming vehicles when the low beam is on. Therefore, in order to meet the anti-dazzle requirements of 50L, anti-dazzle grooves 140 are correspondingly provided on each of the first reflecting surfaces 121. The anti-dazzle grooves 140 are provided at the edge of the cut-off line structure 150. The anti-dazzle grooves 140 damage part of the surface shape of the first reflecting surface 121, and the light reflected by this part of the surface shape corresponds to the 50L point of the low beam.
[0063] Specifically, in combination with Figure 5 and Figure 8 , the anti-dazzle grooves 140 are provided in the root area of the total reflection surface 120. The anti-dazzle grooves 140 can be a hemispherical groove. Exemplarily, its diameter can be 0.4 mm. The anti-dazzle grooves 140 can also be other shapes.
[0064] In a specific embodiment disclosed by the present utility model, light-transferring protrusions 133 are provided on the brightness supplement surface 132. The light-transferring protrusions 133 are provided at the center position of the brightness supplement surface 132 and are used to refract light to a position above the cut-off line to form a three-zone of the low beam light pattern. Exemplarily, there can be two light-transferring protrusions 133, which are respectively provided on one brightness supplement surface 132.
[0065] Among them, the light-transferring protrusions 133 and the inner lens 100 can be an integral structure and are integrally formed.
[0066] In combination with Figure 3 and Figure 10 , the outer lens 200 has a second light incident surface and a second light exit surface 210. The second light incident surface corresponds to the first light exit surface 130; the second light incident surface protrudes in a direction away from the first light exit surface 130, and the second light exit surface 210 protrudes in a direction away from the first light exit surface 130. The outer surface design of the outer lens 200 is free and can meet different styling requirements.

The lamp board is arranged on the radiator 400 and corresponds to the first light-incident surface 110.

The inner lens 100 is arranged on the radiator 400, and the outer lens 200 is connected to the radiator 400.
[0070] Specifically, the lamp board is attached to the heat-exchanging surface of the radiator 400, combined with Figure 14 and Figure 15 , the heat-exchanging surface of the radiator 400 corresponds to the position of the heat-radiating fins of the radiator 400 to ensure the heat dissipation effect.
