When the installation of the components in the dipped headlight is completed, most of the light reflected by the reflector 12 is incident on the first light incident surface 131 of the inner lens 13, but it is difficult to avoid that a small amount of light irradiates the position of the extension 152; meanwhile, the light emitted from the light outlet point of the light source also irradiates the position of the extension portion 152, so as to avoid that the light irradiated to the extension portion 152 is reflected, stray light is formed inside the dipped headlight, the uniformity of the light outlet of the dipped headlight is affected, the surface of the extension portion 152 can be set to be a rough surface, and the rough surface enables the light irradiated to the position to be absorbed, thereby avoiding the occurrence of the above situation.

The surface shape of each cylindrical surface can be specifically set according to the light shape requirement of the dipped headlight. Each cylindrical surface may be the same or different.

In addition, as shown in fig. 13 and 14, the first light-emitting surface 132 has a second included angle with the axis of the cylindrical surface, so that the first light-emitting surface 132 is inclined, and when the first light-emitting surface 132 is inclined, the light path of the light can be changed. For example, the light path of the light beam above the cut-off line formed by the light shape of the dipped headlight may be changed to bend the light beam below the cut-off line, so as to achieve the effect of eliminating the virtual light above the cut-off line, as shown in fig. 15 and 16, wherein fig. 15 is a light shape diagram of the dipped headlight when the first light emitting surface 132 is inclined, and fig. 16 is a light shape diagram when the first light emitting surface 132 is not inclined, as is apparent from fig. 15 and 16, the virtual light above the cut-off line can be effectively improved when the first light emitting surface 132 is inclined.

In one implementation manner of the embodiment of the present utility model, as shown in fig. 7, 8, 9 and 10, the outer lens 14 has a second light incident surface 141 and a second light emergent surface 142 along the light path direction, the second light incident surface 141 is provided with a three-area illumination structure 143, and the three-area illumination structure 143 is a plurality of curved surfaces sequentially connected along a third direction.

According to the utility model, the three-region lighting structure 143 can be arranged on one side of the second light incident surface 141, and compared with the three-region lighting structure 143 arranged on the side surface of the lens in the prior art, the three-region lighting structure 143 can be arranged in the dipped headlight, when the dipped headlight is arranged on the frame, the three-region lighting structure 143 can be hidden in the lamp body appearance design (such as a large lamp decoration ring), on one hand, the consistency and the aesthetic property of the lamp appearance are facilitated, and on the other hand, because the three-region lighting structure 143 is arranged on the second light incident surface 141 of the outer lens 14 and is positioned in the dipped headlight, thereby avoiding the influence of foreign matters such as external particles on the three-region lighting structure 143.

Specifically, the three-area illumination structure 143 may be disposed at any end of the second light incident surface 141 along the second direction (the direction C in fig. 2), which is not limited by the present utility model.

The three-area lighting structure 143 is formed by connecting a plurality of curved surfaces along a third direction, and light emitted from the light source can be emitted into the outer lens 14 from the three-area lighting structure 143 and emitted along the light emitting surface of the outer lens 14, so as to form a three-area light shape part of a low beam light shape.

Alternatively, as shown in fig. 10, the tangential planes of the curved surfaces of the three-area illumination structure 143 define a second plane, and the second plane has a third included angle with the second light incident surface 141.

Specifically, the tangential planes of the curved surfaces of the three-area illumination structure 143 define a second plane, and the second plane and the second light incident surface 141 have a third included angle, as shown in two embodiments in fig. 17 and 18, and fig. 19 and 20, respectively. Through the size of adjusting the third contained angle, can be accurate set up the three district light form parts of low beam light form. For example, the light shape of the three areas can be moved upwards as a whole by adjusting the size of the third included angle, so that the low beam meets the requirement of no glare in the test of the new vehicle evaluation rule under the condition of meeting the rule. Specifically, as shown in fig. 11 and fig. 12, when the second plane forms a third included angle with the second light incident surface 141, the light shape range of the three regions in fig. 11 is about 1 ° to 6 ° above and below the cut-off line of the low beam light shape, and the light shapes of the three regions are not connected with the main light shape of the low beam. When the tangential planes of the curved surfaces are parallel to the second plane, the light shape range of the three regions in fig. 12 is about 0-2 degrees up and down, the light shape of the three regions is connected with the light shape of the main body of the low beam, and therefore, only the angle of the three-region illumination structure is changed, the up and down ranges of the light shape of the three regions can be changed, so that part of three-region test points are avoided, and better light shape performance is obtained while the regulations are met.

In one implementation of the embodiment of the present utility model, the outer lens 14 of the primary low beam module and the outer lens 14 of the auxiliary low beam module have the same structure. In one possible implementation of this embodiment, the heat sink 15 of the primary low beam module and the heat sink 15 of the secondary low beam module are identical in structure. In one possible implementation of this embodiment, the outer lens 14 of the primary low beam module and the outer lens 14 of the secondary low beam module are identical in structure to the heat sink 15.

Since the primary and secondary low beam modules do not have the same effect in illumination (primary and secondary low beam modules are responsible for the brightness of the low beam and secondary low beam modules are responsible for the broadening of the low beam), the specific settings of the light sources of the primary and secondary low beam modules, the reflectors 12 corresponding to the light sources, and the inner lenses 13 corresponding to the light sources are different. The outer lenses 14 and the heat radiator 15 are the same in the main low beam module and the auxiliary low beam module, and at this time, the structures of the outer lenses 14 of the main low beam module and the auxiliary low beam module can be set the same, and the structures of the heat radiator 15 of the main low beam module and the heat radiator 15 of the auxiliary low beam module are set the same, so that the outer lenses 14 of the main low beam module and the auxiliary low beam module are universal, the heat radiator 15 of the main low beam module and the heat radiator 15 of the auxiliary low beam module are universal, and the preparation of the outer lenses 14 and the heat radiator 15 is convenient.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
