The light source 1 is arranged at the focus position of the light inlet end of the lens 2 with the cut-off line structure for emitting the light type of the low beam center bright spot area, and the lens 2 with the cut-off line structure for emitting the light type of the low beam center bright spot area further comprises a primary light distribution surface 3 and a cut-off line structure 5.

The primary light distribution surface 3 is disposed between the light incident surface 201 and the side surface 6 of the lens, and is used for primarily adjusting the light rays 8 emitted from the light source 1 without any blending to reach the light emergent surface of the lens.

As shown in fig. 15, in the prior art, especially in the field of car light modules, a separate lens 4 is generally disposed outside a light distribution lens, and after light passes through the light distribution lens, the emitted light enters the inner surface of a projection lens again and then enters the outer surface of the projection lens through a projection lens body, wherein the inner surface of the projection lens has a light diffusion effect.

The cutoff line structure 5 is provided at and in the vicinity of the focal point of the optical system, the cutoff line structure 5 is provided at a lower-middle position of the lens body 202 as viewed in the vertical direction, and the opening side of the cutoff line structure 5 is downward. The cut-off line structure 5 has a step-like structure, so that the lens system can hit off a cut-off line, and the lens 2 with a cut-off line structure for hitting off a low-beam center bright point area light pattern of the present embodiment is a cut-off line that enables it to hit off a low-beam center bright point area light pattern. As shown in fig. 4, in a preferred embodiment, the step-like structure of the cut-off line structure 5 is configured to have a lower plane, a 45 ° inclined plane inclined upward from the lower left to the right, and an upper plane, wherein the lower plane, the 45 ° inclined plane inclined upward from the lower left to the right, and the ends of the upper plane are sequentially connected, that is, the cut-off line structure of the present embodiment.

When the length in the depth direction is longer, the smaller the angle area presented by the light emitted from the light emitting surface of the lens is, although the area widened to the left and right of the light pattern is small, the light emitting angle is reduced, so that the middle brightness of the light pattern is higher, and the illumination performance is improved. However, the lens 2 of the present embodiment is a central bright spot area of the beam, and has a low demand for broadening, and a higher demand is a central light effect. When the intermediate brightness is desired to be higher, it is realized by flexibly increasing the depth direction length of the lens 2. Another modification of the present embodiment is that when the present embodiment is applied to a low beam basic beam type, it is preferable to reduce the length of the lens 2 in the depth direction, so that the angle of the light emitted from the light exit surface of the lens is increased, and the widening of the beam type is satisfied.

In a preferred embodiment, the material of the lens 2 is selected to increase the light absorption rate and the light effect, so that the brightness of the central area is improved, and if the conventional material can meet the requirement, no special material is required to be further selected.

The side of the lens 2 with the cut-off line structure for emitting the light type of the near light center bright point area has two lens sides 6, and in the preferred embodiment, the lens sides 6 are additionally provided with dermatoglyph which effectively shields stray light and improves the uniformity.

The light rays are emitted from the light source 1, then reach the primary light distribution surface 3, then reach the lens focus 7 after being totally reflected, part of the light rays pass through the upper part of the cut-off line structure 5, then the light rays with cut-off line information are emitted to the light emitting surface of the lens, and part of the light rays are emitted to the lower part of the cut-off line structure 5 to be cut off, so that a dark area above a low beam type is formed, and the driver of an opposite vehicle cannot be dazzled.

The primary light distribution surface 3 and the cut-off line structure 5 are the same in structure and function as those in the lens system in example 2.

As shown in fig. 7, the lens 2 with the cut-off line structure for emitting the high beam central bright spot area light pattern has a lens focus F, the lens focus F is disposed at a midpoint position of an intersection line of a 45 ° inclined plane and a vertical plane of the lens 2 with the cut-off line structure for emitting the high beam central bright spot area light pattern, the emergent light of the light source 1 reaches the primary light distribution surface 3 and then reaches the lens focus F after being totally reflected, and the light is emitted to the light emitting surface of the lens with the cut-off line information.

The length limitation of the depth direction of the lens 2 with the cut-off line structure for emitting the light type of the far-beam central bright spot area light type is not limited by the embodiment, the lens can be adjusted according to the actual project requirement, and the design flexibility is large. The depth direction length is shorter the more, the angle area that the light that goes out the plain noodles from the lens goes out the plain noodles and presents is bigger, the light type is regional can be bigger about widening, visual angle scope about the light type can shine to bigger, the light type that widens about bigger can provide driver self and the car that comes, subtend car, pedestrian's field of vision, effectively avoid because control the light type widen not enough or narrow about that leads to the visual field insufficient and the potential safety hazard that brings, visual field scope can be narrower than conventional condition when crossroad and turn, the visual field is not enough more serious to driver and pedestrian potential safety hazard about if controlling, the regional security that can effectively improve the crossroad about the increase light type, the circumstances such as turn. When the length in the depth direction is longer, the smaller the angle area presented by the light emitted from the light emitting surface of the lens is, although the area widened to the left and right of the light pattern is small, the light emitting angle is reduced, so that the middle brightness of the light pattern is higher, and the illumination performance is improved. However, the lens 2 of the present embodiment is a central bright spot area for focusing distance light, and has a low demand for broadening, and a higher demand is a central light effect. When the intermediate brightness is desired to be higher, it is realized by flexibly increasing the depth direction length of the lens 2. Another modification of this embodiment is that, when the method is applied to a high beam basic light type, it is preferable to reduce the length of the lens 2 in the depth direction, so that the angle of the light emitted from the light emitting surface of the lens is increased, and the light type widening is satisfied.

The material of the lens 2 is preferably selected to increase the light absorption rate and the light effect, so that the brightness of the central area is improved, and if the conventional material can meet the requirement, no special material is required to be further selected.

The side of the lens 2 with the cut-off line structure for emitting the light type of the far-beam central bright spot area is provided with two lens sides 6, and in the preferred embodiment, dermatoglyphs are added on the lens sides 6, so that stray light is effectively shielded, and the uniformity is improved.

As shown in fig. 10, light is emitted from the light source 1, then reaches the primary light distribution surface 3, then is totally reflected, and then reaches the lens focus 7, after a part of the light passes through the lower part of the cut-off line structure 5, the light hits the light emitting surface of the lens with the cut-off line information, and then is emitted, and a part of the light hits the upper part of the cut-off line structure 5 and is cut off, so that a high beam light type with a bright upper part and a dark lower part is formed.

In addition, compared with the lens system in example 2, that is, the lens with the cut-off line structure that emits the low beam center area light pattern and the lens with the cut-off line structure that emits the high beam center area light pattern are different in that the cut-off line structure opening of the lens with the cut-off line structure that emits the low beam center area light pattern is downward as viewed from the top, and the cut-off line structure opening of the lens with the cut-off line structure that emits the high beam center area light pattern is upward as viewed from the top. The reason is that the low beam type requires Fang Liang below the cut-off line, the upper side is dark, the opening is downward, the lower beam is cut off, the upper beam is inverted in the up-down and left-right directions after passing through the light emitting surface of the lens, so that the image is formed below the cut-off line, the high beam type is just opposite in the same way, and the high beam requires that the cut-off line is bright above the cut-off line, so that the opening is upward, and the area above the cut-off line is lightened after the light passes through the light emitting surface of the lens from the lower side and is inverted in the up-down and left-right directions.
