The terminology used is for the purpose of describing the invention only and is not intended to be limiting of the invention since it is the intention of the inventors to specify or imply that the apparatus or component referred to must be constructed and operated in a particular orientation based on the orientation or positional relationship illustrated in the drawings.
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "connected" are to be interpreted broadly, e.g., as either a fixed connection, a removable connection, or an integral connection; either directly or indirectly through intervening media, either internally or in any combination thereof. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
As shown in fig. 1 to 6 and 15 to 20, the present invention provides a headlamp optical assembly, which includes a light collecting element 1 and a lens holder 2 that are integrally formed, wherein the light collecting element 1 includes a collimating unit module having a plurality of collimating units 11 arranged in a left-right direction, a single collimating unit 11 includes a light incident portion 111, a light guide portion 112 and a light emergent portion 113, and one end of the collimating unit module, which is close to the light emergent portion 113, is integrally formed with a widening and expanding structure 13, so that widening of a single-pixel light shape correspondingly formed by the headlamp optical assembly can be increased by the widening and expanding structure 13.
As shown in fig. 1 to 6, a collimating unit module is formed on a light-collecting element 1 of the present invention, the collimating unit module has a plurality of collimating units 11 arranged in a left-right direction, light correspondingly forms a single-pixel light shape through a single collimating unit 11 in a headlamp optical assembly, and a widening and expanding structure 13 is integrally provided on a left side or a right side of the collimating unit 11 in the collimating unit module, so that the widening of the corresponding formed single-pixel light shape is effectively increased after the light passes through the widening and expanding structure 13.
Note that the spread can be understood as the width of the single-pixel light shape in the left-right direction. The light-gathering element 1 comprises a row of collimation unit modules, a single row of collimation unit modules comprises a plurality of collimation units 11 arranged side by side, and the widening expansion structure 13 can be arranged on the left side or the right side of any collimation unit 11 or on the left side and the right side of the same collimation unit 11. In addition, the light condensing element 1 may also be configured as two or more rows of collimating unit modules, and according to the light emitting requirement, the widening and expanding structure 13 may be disposed on any collimating unit 11, so as to meet the widening and expanding requirement of the single-pixel light shape correspondingly formed by the headlamp optical assembly.
In addition, the single-pixel light pattern described in the present invention is formed not by directly projecting the outgoing light of the headlamp optical assembly, but by projecting the outgoing light through the secondary optical element 3.
In a preferred embodiment of the present invention, the light emitting portions 113 are integrally formed as the light emitting portions of the light collecting element 1, a wedge-shaped gap 12 is formed between the light guiding portions 112, and the width of the wedge-shaped gap 12 is gradually reduced along the light emitting direction.
It should be understood that the light-emitting portion 113 of the present invention is integrally formed as the light-emitting portion of the light-condensing element 1, and the light-emitting surface of the light-emitting portion of the light-condensing element 1 may be formed as a smooth plane or a curved surface, or may be formed as light-emitting surfaces independently arranged as shown in fig. 1 to 6.
The wedge-shaped gaps 12 are formed among the light guide parts 112, the width of each wedge-shaped gap 12 in the left-right direction is gradually reduced along the light emitting direction, so that the collimating unit module is formed into a fan shape, the distance between the light entering parts 111 is longer, which is beneficial to heat dissipation of the part, and the light emitting parts 113 are gathered, which can converge more light rays to the next optical element (i.e. the secondary optical element 3 shown in fig. 22 to 24), thereby improving the light emitting efficiency.
As another preferred embodiment of the present invention, the widening expansion structure 13 includes a first widening expansion structure 131, a second widening expansion structure 132, a third widening expansion structure 133, and a fourth widening expansion structure 134, where the first widening expansion structure 131 is disposed on an outer side surface of one of left and right sides of the collimating unit module, the fourth widening expansion structure 134 is disposed on an outer side surface of the other side of the collimating unit module, and the second widening expansion structure 132 and/or the third widening expansion structure 133 are/is disposed on the collimating unit 11 of the collimating unit module except for the collimating units 11 on the left and right sides.
According to the light emitting requirement, the first widening expansion structure 131 and the fourth widening expansion structure 134 are arranged on the left side surface of the collimating unit 11 at the left end part and the right side surface of the collimating unit 11 at the right end part of the collimating unit module, and the first widening expansion structure 131 and the fourth widening expansion structure 134 are not limited to the left side or the right side of the corresponding collimating unit module and are set according to the actual light emitting requirement.
More preferably, at least one of outer side surfaces of the spread spreading structure 13 in the left-right direction is formed as a plane inclined outward from back to front, as shown in a third spread spreading structure 133 in fig. 12.
It should be noted that the outward inclination of the present invention is based on the collimating unit module shown in fig. 6, and the outward inclination can be understood as inclination from the directions of both sides of the rear-to-front collimating unit module in the left-to-right direction of the collimating unit module.
In addition, as an embodiment of the present invention, the widening expansion structure 13 may be formed as a rib protruding outward, such as a first widening expansion structure 131 shown in fig. 7 and a second widening expansion structure 132 shown in fig. 9, or as a curved surface bending forward and outward, and the specific structure thereof is designed according to the actual light shape expansion requirement and illumination requirement, such as a fourth widening expansion structure 134 shown in fig. 6.
As another preferred embodiment of the present invention, as shown in fig. 7 and 8, a first spread structure light exit surface 1311 is formed on the first spread structure 131, and the first spread structure light exit surface 1311 is located in front of or behind the light exit surface of the light exit portion 113. Therefore, the position of the light exit surface 1311 is designed according to different left and right angles and different illumination intensities which need to be expanded by the corresponding single-pixel light shape; as shown in fig. 10 and 12, the light emitting surfaces of the second spread structure 132, the third spread structure 133 and the fourth spread structure 134 are formed as at least a part of the light emitting surface of the light emitting portion 113 of the collimating unit 11 connected to each other.
According to the light emitting requirement, the first widening expansion structure light emitting surface 1311 of the first widening expansion structure 131 and the light emitting surface of the light emitting portion 113 of the collimating unit 11 where the first widening expansion structure is located are separately arranged, the light shape formed by the collimating unit 11 where the first widening expansion structure 131 is located is as shown in fig. 9, the light shape shown in the dashed line frame in the figure is the light shape 131a formed by the first widening expansion structure, and it can be seen that the right widening of the single-pixel light shape formed by the collimating unit 11 is effectively expanded. While the light-exiting surfaces of the second broadening extension structure 132, the third broadening extension structure 133 and the fourth broadening extension structure 134 are formed as at least a part of the light-exiting surface of the light-exiting portion 113 of the respective connected collimating unit 11, preferably, the light-exiting surfaces of the second broadening extension structure 132, the third broadening extension structure 133 and the fourth broadening extension structure 134 share the light-exiting surface of the light-exiting portion 113 of the respective connected collimating unit 11, the light shapes correspondingly formed by the respective connected collimating units 11 are respectively shown in fig. 11, 13 and 14, the light shape correspondingly formed by the second broadening extension structure is shown in the dashed rectangular box in fig. 11 as a light shape 132a which extends the right-side broadening of the corresponding single-pixel light shape, the light shape correspondingly formed by the third broadening extension structure is shown in the dashed rectangular box in fig. 13 as a light shape 133a which extends the left-side broadening of the corresponding single-pixel light shape, the light shape correspondingly formed by the fourth broadening extension structure is shown in the dashed rectangular box in fig. 14 as a light shape 134a, which extends the left-side broadening of the corresponding single-pixel light shape. It can be seen that the placement of the broadening extension structure 13 on the left or right side of the collimating element 11 may influence the broadening extension direction of the correspondingly formed single-pixel light shape of the collimating element 11. Further, since the light emitting effect of the flare extending portion light pattern can be also considered to be affected by the angle at which the outer side surface of the flare extending structure 13 is inclined outward and the length of the outer inclined surface of the flare extending structure 13, it is considered to be within the scope of the present invention to change the flare of the formed single-pixel light pattern by changing the structural shape, the installation position, the outer side surface inclination angle, the front-rear extension length of the outer inclined surface, and the like of the flare extending structure 13. Meanwhile, it is also conceivable that the configuration of each spread-extending structure 13 in the present invention is changed according to the direction and angle in which each single-pixel light shape needs to be extended, and the illuminance of each single-pixel light shape.
As a specific configuration form of the present invention, a cavity adapted to accommodate the light-collecting element 1 is formed on the lens holder 2, an engaging structure adapted to engage with each other is formed in the cavity and the light-collecting element 1, and the light-collecting element 1 is engaged in the cavity through the engaging structure.
Specifically, the fitting structure includes an insertion portion 21 provided on the inner peripheral wall of the cavity and an insertion groove 14 provided at the front end of the light condensing element 1. As can be seen from fig. 21, a cavity capable of accommodating the light condensing element 1 is formed on the lens holder 2, and a fitting structure which is fitted with each other is formed on the periphery of the inner side of the cavity and the periphery of the front end of the light condensing element 1, more specifically, an insertion portion 21 is formed on the lens holder 2, and accordingly, an insertion groove 14 which is fitted with the insertion portion 21 is formed on the light condensing element 1, and the insertion groove 14 is integrally formed on the periphery of the front end of the light condensing element 1, so that not only the mounting requirement can be satisfied, but also the rigidity of the light condensing element 1 can be improved.
More specifically, the insertion portion 21 is formed around the inner circumferential wall of the cavity, and a plurality of through holes 211 penetrating through the insertion portion 21 are formed in the insertion portion 21.
As another specific structure form of the present invention, the insertion groove 14 is a groove body adapted to be inserted by the insertion portion 21, and the insertion groove 14 is integrally formed with the column bodies 15 that can be inserted into the through holes 211 in a one-to-one correspondence.
More specifically, the caulking groove 14 is integrally formed around the light exit portion of the light collecting element 1.
The fitting structure of the present invention is to fit the fitting portion 21 into the fitting groove 14, and also fit the column 15 and the through hole 211 together in order to make the fitting structure more firm and higher in fitting strength, and the fitting structure can firmly fit the light collecting element 1 and the lens holder 2 into a whole. Note that, when the light collecting element 1 and the lens holder 2 are firmly fitted together, they are inseparable from each other, and fig. 15 to 20 show two components only for showing the specific configurations of the two components.
As can be seen from fig. 15 to 20, the light condensing element 1 and the lens holder 2 of the present invention are integrally formed members, which can avoid the installation error between the light condensing element 1 and the lens holder 2 due to multiple positioning, improve the positioning and installation accuracy between the light condensing element 1 and the lens holder 2, simplify the installation structure between the light condensing element 1 and the lens holder, and directly improve the light emitting effect of the headlamp.
