[0047] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0048] As Figure 2 shown, the embodiment of the present utility model discloses a headlight module, including a light source 100 and an optical element 200.
[0049] Among them, the light source 100 is preferably an LED particle, such as Figure 1 and Figure 3 As shown, the optical element 200 is an integral structure, including two light-emitting modules arranged along the first direction. The light-emitting module includes a light-incident unit 210 and a lens unit 220 disposed on the light-emitting side of the light-incident unit 210. The light-incident unit 210 and the lens unit 220 are arranged along the second direction, and the first direction and the second direction are perpendicular. The light-incident unit 210 includes a plurality of condensing structures 211, the lens unit 220 includes light-emitting surfaces 221 corresponding to the condensing structures 211 one by one, and the plurality of light-emitting surfaces 221 are connected in sequence. One of the light-emitting modules is a low-beam light-emitting module 201, and the other is a high-beam light-emitting module 202, that is, both the low-beam light-emitting module 201 and the high-beam light-emitting module 202 include a light-incident unit 210 and a lens unit 220. The light emitted by the light source 100 enters the lens unit 220 through the light-incident unit 210, and forms a corresponding light pattern after being emitted from the light-emitting surface 221 of the lens unit 220.
[0050] It should be noted that the shapes of the condensing structures 211 include various types. The condensing structure 211 preferably has the shape of a condensing cup, and the respective condensing structures 211 are arranged at intervals.
[0051] Such as Figure 8 As shown, the light-incident units 210 of both the low-beam light-emitting module 201 and the high-beam light-emitting module 202 include a plurality of condensing structures 211, and the plurality of condensing structures 211 are arranged at intervals along the first direction. The light-emitting surfaces 221 of the lens unit 220 are arranged along the first direction, so that the optical element 200 as a whole has a narrow strip shape. The first direction can be the vertical direction (here referring to the direction perpendicular to the vehicle body width direction and the vehicle body length direction), or the horizontal direction (here referring to the direction parallel to the vehicle body width direction), and the vertical direction is preferred. The second direction is perpendicular to the first direction. When the first direction is the vertical direction, the second direction refers to the direction parallel to the vehicle body length direction.
[0052] In the headlight module disclosed in the embodiment of the present utility model, the optical element 200 is an integral structure, integrating the low-beam light-emitting module 201 and the high-beam light-emitting module 202 into one. Compared with the prior art, the number of parts is reduced, the assembly difficulty can be reduced, the error caused by part assembly is reduced, and the lighting effect can be improved; the light-incident unit 210 includes a plurality of condensing structures 211, and the plurality of condensing structures 211 are arranged at intervals. Compared with the continuous-surface condensing structure 211 in the prior art, the utilization rate of light can be improved and the light efficiency can be improved; the low-beam light-emitting module 201 and the high-beam light-emitting module 202 are arranged along the first direction, so that the headlight module as a whole is arranged in a narrow strip shape, the size of the headlight module can be reduced, and the occupied space can be reduced.
[0053] In some specific embodiments, the height and width of the optical element 200 are both 25 mm. Compared with the height and width of the headlight module in the prior art, which are both 40 mm, the size of the headlight module is reduced, and the occupied space can be reduced. It should be noted that the headlight module disclosed in the embodiments of the present invention can be arbitrarily added with light units 210 and lens units 220 as needed to meet the design requirements of different brands of vehicles.
[0054] To expand the irradiation range of the low-beam light-emitting module, in some specific embodiments, as Figures 4 - 5 shown, the low-beam light-emitting module 201 includes at least two condensing structures 211. One of the condensing structures 211 is a low-beam broadening condensing structure 2011 to form the broadening of the low-beam light pattern, and the remaining condensing structures 211 are low-beam condensing structures 2012. The low-beam light-emitting module 201 shown in the figure includes two low-beam condensing structures 2012 and one low-beam broadening condensing structure 2011. The arrangement of multiple low-beam condensing structures 2012 can improve the lighting effect and reduce potential safety hazards caused by insufficient light. The number shown in the figure is only an example and does not constitute a limitation. In some specific embodiments, the light source 100 corresponding to the low-beam broadening condensing structure 2011 is a dual-core LED particle, and the light sources 100 corresponding to the remaining low-beam condensing structures 2012 are single-core LED particles.
[0055] Specifically, as Figure 11 and Figure 12 shown, a step structure 2013 is provided on the low-beam broadening condensing structure 2011. Specifically, the step structure 2013 is provided on the reflection part of the low-beam broadening condensing structure 2011. It is arranged along the third direction, which is perpendicular to both the first direction and the second direction, and the third direction is preferably the vehicle body width direction. The step structure 2013 is provided on the low-beam broadening condensing structure 2011 and is symmetrically arranged along the axis of the low-beam broadening condensing structure 2011. The arrangement of the step structure 2013 can expand the irradiation range of the low-beam light-emitting module, obtain the broadening of the low-beam light pattern, increase the lighting range, and improve driving safety.
[0056] In some specific embodiments, at least one groove 222 is provided on the lens unit 220 of the low-beam light-emitting module 201. One groove 222 can be provided, and the extending direction of the groove 222 is the length direction of the optical element 200. The setting of the groove 222 can increase the refracting surface and enable flexible light distribution. The groove 222 is preferably a V-shaped groove and is preferably arranged in a one-to-one correspondence with the condensing structure 211 of the low-beam light-emitting module 201.
[0057] As Figures 5 - 8As shown, in some specific embodiments, the groove 222 includes a plurality of grooves corresponding one-to-one to the condensing structure 211 of the low beam light-emitting module 201. Among them, a cut-off structure 2222 for forming a low beam cut-off line is provided on the groove 222 corresponding to the low beam condensing structure 2012. The shape of the cut-off structure 2222 corresponds to the shape of the low beam cut-off line, and according to actual needs, a 45-degree cut-off line or a 15-degree cut-off line can be formed. As Figure 7 shown, a broadening cut-off line 2221 is provided on the groove 222 corresponding to the low beam broadening condensing structure 2011. Specifically, the broadening cut-off line 2221 is a straight line. This design method can reduce the occurrence of the phenomenon that stray light exceeds the regulatory value. As Figures 16 - 18 shown, the figure shows a schematic diagram of the low beam light pattern generated by the low beam light-emitting module 201, and the figure shows the inflection point of the 45-degree cut-off line. Specifically, as Figure 18 shown, of course, by changing the shape of the cut-off structure 2222, a 15-degree low beam cut-off line can be formed
[0058] As Figures 9 - 10 shown, the figure respectively shows the optical path schematic diagrams of the low beam broadening condensing structure 2011 and the low beam condensing structure 2012. It can be seen from the figure that the light rays emitted by the light source 100 can expand the illumination range through the low beam broadening condensing structure 2011. As Figure 11 and Figure 20 shown, the figure shows a schematic diagram of the light pattern after the light rays emitted by the light source 100 pass through the low beam broadening condensing structure 2011 and the corresponding lens unit 220. Part A in the figure is Figure 11 the light rays b passing through the step structure 2013 converge in the far field or near the non-converging groove 222, and part B is Figure 11 the light rays a passing through the reflection part converge near the groove 222. The light rays a and b have different focal points. Part B in the figure is the converging light rays with high light intensity, and part A is a light spot with a certain width. Part B and the yellow light spot form the broadened low beam light pattern. This method can reduce stray light on the other hand.
[0059] From Figure 19 it can be seen that the area circled by the inner circle in the figure is the area with strong illumination, and the area circled by the outer circle has a width, that is, by setting the low beam broadening condensing structure 2011, the broadening of the low beam light pattern is obtained.
[0060] As Figure 10 and Figure 13As shown, the light-emitting surface 221 includes a low-beam broadening light-emitting surface 2211, which is correspondingly arranged with the low-beam broadening light-condensing structure 2011. The low-beam broadening light-emitting surface 2211 includes a first extension part and a second extension part. The first extension part extends along the first direction, and the second extension part extends along the second direction. The first direction and the second direction are perpendicular. It should be noted that the first direction refers to the vertical direction (perpendicular to the vehicle body width direction and the vehicle body length direction), and the second direction refers to the horizontal direction (parallel to the vehicle body length direction), that is, the low-beam broadening light-emitting surface 2211 has a larger extension range in the first direction and the second direction compared with the light-emitting surfaces 221 of other low-beam light-emitting modules 201.
[0061] As Figure 4 shown, in some specific embodiments, the high-beam light-emitting module 202 includes at least two light-condensing structures 211. One of the light-condensing structures 211 is a high-beam broadening light-condensing structure 2021, and the remaining light-condensing structures 211 are high-beam light-condensing structures 2022. In the figure, there is one high-beam broadening light-condensing structure 2021 and one high-beam light-condensing structure 2022 shown. The figure is only an example and cannot be used as a limitation. The specific number of the high-beam light-condensing structures 2022 can be determined according to actual needs.
[0062] In some specific embodiments, the high-beam broadening light-condensing structure 2021 includes two light-condensers in the shape of a light-condensing cup. The high-beam broadening light-condensing structure 2021 includes a plurality of light-condensing curved surfaces, which can realize the optimized reflection and light-condensing effect of the high beam. Figures 14 - 15 The optical path diagram of the light emitted by the light source 100 passing through the high-beam broadening light-condensing structure 2021 and the high-beam light-condensing structure 2022 is shown. It can be seen from the figure that the setting of the high-beam broadening light-condensing structure 2021 increases the irradiation range and can improve the driving safety. Figures 20 - 23 The high-beam light pattern diagram and the light pattern diagram of the superposition of the low beam and the high beam are shown. It can be seen from the figure that the illumination range is large and the stray light is less.
[0063] As Figure 5 shown, in the headlight module disclosed in the embodiment of the present invention, each light-emitting surface 221 is a convex curved surface, and each light-emitting surface 221 is connected in sequence.
[0064] The headlight module disclosed in the embodiment of the present invention further includes a circuit board and a heat dissipation module. The light source 100 is arranged on the circuit board, and both the circuit board and the optical element 200 are arranged on the heat dissipation module. Specifically, the circuit board can be installed on the heat dissipation module through the limit posts, and the optical element 200 is installed on the heat dissipation module through the limit and screws.
