These headlamps can generally be used according to two illumination modes: a "high beam" mode and a "low beam" mode. The "high beam" mode causes the road far in front of the vehicle to be illuminated, risking blinding users approaching in the opposite direction on the road. The "low beam" mode produces more limited illumination of the road, but still provides good visibility without blinding other users of the road. The two illumination modes are complementary. The driver of the vehicle must manually change the mode depending on the lighting conditions and other users of the road. The fact that the mode must be changed manually can make the reliability insufficient and in some cases prove dangerous. Further, the high beam mode sometimes results in insufficient visibility for the vehicle driver.
To improve this situation, current motor vehicles are provided with headlights with an ADB (adaptive high beam) adaptive lighting function aimed at automatically detecting road users susceptible to blinding by the illuminating light beam emitted by the headlights in high beam mode, and to adjust the profile of said illuminating light beam in such a way as to form dark zones at the position of the detected user. To implement such ADB functionality, for example, a lighting module is known that comprises at least two sub-modules, each sub-module comprising at least two light sources, the sub-modules being separated by a partition, enabling the light sources to generate localized light beams, projected through projection optics to form corresponding light emitting sections, and the partition absorbing stray light, with low optical efficiency, and with a large number of modular parts and a complex optical system.

As shown in fig. 1 to 4, the high beam illumination module according to the basic embodiment of the present invention includes a light source 1, a reflective element and an optical lens, wherein the reflective element is arranged to reflect light emitted from the light source 1 into the optical lens, the optical lens includes an incident portion having horizontal unidirectional collimation and an emergent portion 2 having vertical unidirectional collimation, the reflective element includes a plurality of reflectors 3 connected in sequence, the light source 1 and the reflectors 3 are arranged in a one-to-one correspondence, the incident portion includes at least one incident surface 4, and each incident surface 4 is respectively arranged in correspondence to the plurality of reflectors 3.
Referring to fig. 5 to 10, the present invention designs an optical lens, so that the light incident surface 4 has an optical characteristic of collimating divergent light rays in a single direction in a horizontal direction, and the light emergent surface 2 has an optical characteristic of collimating divergent light rays in a single direction in a vertical direction; it should be noted that the "horizontal unidirectional collimation" can be understood as follows: as shown in fig. 13, in a horizontal cross section, a sectional line of the light incident surface 4 in the horizontal direction is a convex curve, which has a convergence effect, has a large deflection degree on light rays, and can have a certain collimation effect on divergent light rays, as shown in fig. 14, in a vertical cross section, a sectional line of the light incident surface 4 in the vertical direction is a straight line or an almost straight line, so that the deflection capability of the light incident surface 4 on the divergent light rays is far inferior to the deflection capability of the light incident surface 4 on the divergent light rays in the horizontal cross section, and has no collimation effect, and the light incident surface 4 has a single-direction collimation effect on the divergent light rays in the horizontal cross section position range, that is, the light incident surface 4 mainly deflects the light rays in the horizontal direction; similarly, the "vertical unidirectional collimation" can be understood as follows: as shown in fig. 14, in a vertical cross section, a sectional line of the light emitting portion 2 in the vertical direction is a convex curve, which has a converging effect, has a large deflection degree on light, and can have a certain collimation effect on divergent light, as shown in fig. 13, in a horizontal cross section, a sectional line of the light emitting portion 2 in the horizontal direction is a straight line or an almost straight line, so that the deflection capability of the light emitting portion 2 on the divergent light is far inferior to the deflection capability of the light emitting portion 2 on the divergent light in the vertical cross section, and has no collimation effect, and the light emitting portion 2 has a single-direction collimation effect on the divergent light in the vertical cross section position range, that is, the light emitting portion 2 mainly deflects light in the vertical direction; according to the structural design of the optical lens, the light incident surface 4 mainly deflects light rays in the horizontal direction, and the light emergent portion 2 mainly deflects light rays in the vertical direction, so that the imaging magnification of the light incident surface 4 to the light source 1 in the horizontal direction is larger than that of the light emergent portion 2 to the light source 1 in the vertical direction, and the light source 1 can form a rectangular illumination light shape through the optical lens, the size of the light emergent portion 2 in the vertical direction is allowed to be designed to be smaller, and the requirement of narrow and long shape is met; moreover, for the common spherical lens in the prior art, because the light incident surface and the light emergent surface have large deflection capability to light rays in each direction, in the light distribution design process, the plane shapes of the two optical surfaces of the light incident surface and the light emergent surface need to be considered simultaneously to enable the emergent light rays of the light emergent surface to be projected to form an expected illumination light shape, the light distribution process needs to repeatedly adjust the two optical surfaces, and the light distribution process is complex. Meanwhile, each light incident surface 4 is arranged corresponding to the plurality of reflectors 3, and the structural design can enable the vehicle lamp to realize an ADB self-adaptive high beam function, for example, when the high beam lighting module is applied to a specific vehicle, when other users on a road in an opposite lane are detected during night driving, the high beam light areas corresponding to the other detected users on the road can form dark areas by controlling the on and off of the light sources 1, so that the possibility of safety accidents caused by dazzling of the other detected users on the road is avoided; because the light sources 1 and the reflectors 3 are arranged in a one-to-one correspondence manner, each light source 1 can be reflected to the corresponding light inlet surface 4 by the corresponding reflector 3, and the light sources 1 and the reflectors 3 are arranged along the left and right directions, because the light inlet surface 4 has a single-direction collimation effect on light within the horizontal section position range, the light is transmitted and irradiated to the light outlet part 2, and the light sources 1, the reflectors 3 and the light inlet surface 4 are matched, so that the waste of the light can be avoided, and the optical efficiency is improved; compared with the prior art, the integrated control system is simple in structure and high in integration level on the whole.
Specifically, the light incident surface 4 can be regarded as a curved surface formed by stretching a sectional line in a horizontal direction thereof along a sectional line in a vertical direction thereof, for example, referring to fig. 6, 8, and 10, the sectional line of the light incident surface 4 in the horizontal direction is a backward convex curve, and the sectional line thereof in the vertical direction is a straight line; similarly, the light emergent portion 2 can be regarded as a curved surface formed by stretching a sectional line in the vertical direction along a sectional line in the horizontal direction, and for example, referring to fig. 5, 8, and 10, the sectional line of the light emergent portion 2 in the vertical direction is a forward convex curve, and the sectional line thereof in the horizontal direction is a straight line.
Further, one of the light incident surface 4 and the light emergent surface 2 is a cylindrical surface, the other is a cylindrical surface, or both are cylindrical surfaces or cylindrical surfaces; referring to fig. 13, in a horizontal cross section, a sectional line of the light incident surface 4 in the horizontal direction is a convex curve, which has a convergence effect, and has a large deflection degree on light rays, and can have a certain collimation effect on divergent light rays, referring to fig. 14, in a vertical cross section, a sectional line of the light incident surface 4 in the vertical direction is a straight line or an almost straight line, so that the deflection capability of the light incident surface 4 on the divergent light rays is far inferior to the deflection capability of the light incident surface 4 on the divergent light rays in a horizontal cross section, and has no collimation effect, and the light incident surface 4 has a single-direction collimation effect on the divergent light rays in a horizontal cross section position range, that is, the light incident surface 4 mainly deflects the light rays in the horizontal direction; however, a sectional line of the cylindrical surface formed by the light incident surface 4 in the horizontal direction is preferably circular arc, and it is needless to say that a sectional line of the light incident surface 4 in the horizontal direction is not necessarily circular arc. Similarly, the present invention is also applicable to the light emitting portion 2; as shown in fig. 14, in a vertical cross section, a sectional line of the light emitting portion 2 in the vertical direction is a convex curve, which has a convergence effect, has a large deflection degree on light, and can have a certain collimation effect on divergent light, as shown in fig. 13, in a horizontal cross section, a sectional line of the light emitting portion 2 in the horizontal direction is a straight line or an almost straight line, so that the deflection capability of the light emitting portion 2 on the divergent light is far inferior to the deflection capability of the light emitting portion 2 on the divergent light in the vertical cross section, and has no collimation effect, and the light emitting portion 2 has a single-direction collimation effect on the divergent light in the vertical cross section position range, that is, the light emitting portion 2 mainly deflects light in the vertical direction; a sectional line of the cylindrical surface formed by the light emergent portion 2 in the vertical direction is preferably circular arc, and a sectional line of the light emergent portion 2 in the vertical direction does not necessarily have to be circular arc. The cylindrical surface-like surface is a curved surface which is close to the cylindrical surface in shape, and has the similar technical effect with the cylindrical surface.
In general, the light emission center of the light source 1 is set in the focal region of the corresponding mirror 3, which is a region near the focal point including the focal point. Specifically, the light emitting center of the light source 1 may be disposed at the focal point of the reflector 3, and the light emitting center of the light source 1 may be deviated from the focal point by a certain distance according to the requirement of light distribution, for example, the distance between the light emitting center of the light source 1 and the focal point of the reflector 3 is less than or equal to 2 mm. The reflector 3 may be a parabolic reflector or a parabolic reflector.
To facilitate an understanding of the technical concepts and advantages of the high beam lighting module of the present invention, a relatively comprehensive set of preferred features of the present invention is described below.
As shown in fig. 1 to 10, the high beam illumination module according to the preferred embodiment of the present invention includes a light source 1, a reflective element and an optical lens, the reflective element includes a plurality of reflectors 3 connected in sequence, the reflectors 3 are preferably parabolic reflectors, the light source 1 and the reflectors 3 are arranged in a one-to-one correspondence, the light source 1 is arranged in a focal region of the corresponding reflector 3, and a distance between a light emitting center of the light source 1 and a focal point of the corresponding reflector 3 is less than or equal to 2mm, preferably, the light emitting center of the light source 1 is arranged at the focal point of the corresponding reflector 3; the optical lens comprises an incident part and an emergent part 2, wherein the incident part has a single-direction collimation effect on light rays within the range of horizontal section positions, the emergent part 2 has a single-direction collimation effect on light rays within the range of vertical section positions, the incident part comprises at least one incident surface 4, the incident surfaces 4 are sequentially connected, similarly, the incident surfaces 4 have a single-direction collimation effect on light rays within the range of horizontal section positions, and each incident surface 4 corresponds to a plurality of reflectors 3; the light emitted from the light source 1 can be reflected by the corresponding reflector 3 to form approximately parallel light beams, and the light beams can be emitted to the corresponding light incident surface 4 and emitted from the light emergent portion 2 to form a high beam shape. One of the light incident surface 4 and the light emergent surface 2 is a cylindrical surface, and the other is a quasi-cylindrical surface, or both the light incident surface 4 and the light emergent surface 2 are cylindrical surfaces or quasi-cylindrical surfaces.
In the above technical solution, the reflectors 3 are arranged in a left-right direction, and the light incident surfaces 4 are also arranged in a left-right direction; by controlling the turning on and off of each light source 1, when all the light sources 1 are in the on state during night driving, a high beam shape as shown in fig. 11 can be formed, and when other users on the road in the opposite lane are detected, as shown in fig. 12, the turning off of each corresponding light source 1 can be controlled, so that a dark area is formed in the high beam shape area at the corresponding position of the detected other users on the road, thereby avoiding dazzling other users on the road and preventing safety accidents. Each light incident surface 4 corresponds to the arrangement mode of the plurality of reflectors 3, each reflector 3 corresponds to the light shape of one region, and the regions corresponding to the reflectors 3 can form dark regions by combining the control of each light source 1, so that the ADB self-adaptive high beam function is realized; moreover, because the light incoming surface 4 mainly deflects the light in the horizontal direction, the light outgoing portion 2 mainly deflects the light in the vertical direction, so that the imaging magnification of the light incoming surface 4 to the light source 1 in the horizontal direction is greater than that of the light outgoing portion 2 to the light source 1 in the vertical direction, and the light source 1 can form a rectangular illumination light shape through the optical lens, meanwhile, compared with the common spherical lens in the prior art, the utility model reduces the upper and lower sizes of the optical lens on the premise of ensuring the same light efficiency, namely, the upper and lower sizes of the light outgoing portion 2 can be allowed to be set to be less than or equal to 20mm, so that a long and narrow far-reaching illumination module can be obtained, and higher optical efficiency can be obtained under the condition that the upper and lower sizes are limited; for example, the optical efficiency can reach 44-50% (including external configuration loss) by designing the vertical dimension of the light-emitting portion 2 to be 15mm, which is equivalent to the optical efficiency of the lens opening of the prior art to be more than 30mm (especially more than 40 mm).
In addition, the high beam lighting module can be applied to a car lamp, the light source 1 is arranged on a circuit board, and the circuit board is connected with a radiator to radiate heat generated by the circuit board; the spare part is less, and on the whole, the structure is simplified.
