Description

Technical Field

[0001] The present invention relates to a constituent device of a vehicle, and particularly to a headlight device. Background Art

[0002] Referring to Figure 1 , an existing headlight device includes a first light-emitting unit 111 capable of projecting light forward, and a first lens unit 112 disposed in front of the first light-emitting unit 111. After the light projected by the first light-emitting unit 111 enters the first lens unit 112, it will be emitted forward from the front end of the first lens unit 112. That is to say, in such a headlight device, the projection direction of the light of the first light-emitting unit 111 and the emission direction of the light emitted from the first lens unit 112 are the same.

[0003] Referring to Figure 2 , another existing headlight device includes two second light-emitting units 121 spaced apart vertically, and a second lens unit 122 located between the upper and lower second light-emitting units 121. Each of the second light-emitting units 121 can project light from top to bottom or from bottom to top. After the light projected by each of the second light-emitting units 121 enters the second lens unit 122, it will be emitted forward from the front end of the second lens unit 122. That is to say, in such a headlight device, the projection direction of the light of each of the second light-emitting units 121 and the emission direction of the light emitted from the second lens unit 122 are perpendicular to each other.

[0004] Although there are already designs where the projection direction and the emission direction are the same and where the projection direction and the emission direction are perpendicular, the light projection direction is still only one kind, and there is a need to provide a product superior to these two designs to promote the healthy competition and development of the industry. Summary of the Invention

[0005] The object of the present invention is to: improve at least one shortcoming of the prior art.

[0006] The headlight device of the present invention includes an optical lens and a light-emitting unit. The optical lens includes a first light-emitting lens portion and a first light-incident lens portion connected front and back.

[0010] In the headlight device of the present invention, the extended lines of the first light rays incident on the first main light-incident surface intersect at the first focal point, and the extended lines of the first light rays incident on the first side light-incident surface intersect to form a plurality of first virtual focal points. Each of the first virtual focal points and the first focal point are the two focal points of the two curves of a hyperbola.

[0011] In the headlight device of the present invention, the first reflecting surface includes two first surface segments spaced vertically and extending forward from the first end, two second surface segments spaced horizontally and extending forward from the first end, and a plurality of third surface segments extending forward from the first end and located between the first surface segments and the second surface segments. Each of the third surface segments is discontinuous with the adjacent first surface segments and second surface segments.

[0012] In the headlight device of the present invention, the second light incident lens part includes a second end and forms a second light collecting space recessed from the second end towards the first light emitting lens part. The second light collecting space is for the second light rays to enter. The second light incident lens part further includes a second main light incident surface located between the second light collecting space and the first light emitting lens part, a second side light incident surface surrounding the second main light incident surface and cooperating with the second main light incident surface to define the second light collecting space, and a second reflecting surface extending from the second end and connecting to the first light emitting lens part and surrounding the second light collecting space.

[0013] In the headlight device of the present invention, the second light rays incident through the second main light incident surface travel towards the inclined reflecting surface along a projection direction transverse to the front-rear direction. The light rays incident through the second side light incident surface and reflected by the second reflecting surface travel towards the inclined reflecting surface along the projection direction.

[0014] In the headlight device of the present invention, the second main light incident surface defines a second focal point. The second light emitting module is located at the second focal point. The second reflecting surface is formed by winding a section of a parabola around the second optical axis and defines several parabolic focal points. The extension lines of the light rays incident through the second side light incident surface intersect at the parabolic focal points.

[0015] In the headlight device of the present invention, the first light rays do not enter the second light emitting lens part and are not emitted from the second light emitting surface, and the second light rays are not emitted from the first light emitting surface.

Therefore, the present invention has the characteristics of being able to emit different first light rays and second light rays and having two of the functions of high and low beam lights / turn signal lights / driving lights and other headlight functions.

[0027] Referring to Figure 3 、 4 、5, an embodiment of the vehicle lamp device of the present invention includes a lamp housing 21 (see Figure 3 ), a heat sink 22 assembled on the lamp housing 21, a first circuit board 23 mounted on the heat sink 22, a second circuit board 24 with a normal vector perpendicular to the normal vector of the first circuit board 23, a light emitting unit 3 mounted on the first circuit board 23 and the second circuit board 24, and an optical lens 4 mounted on the heat sink 22 and the first circuit board 23.

[0028] The lamp housing 21 is generally rectangular ring-shaped. The heat sink 22 is a fin-type heat sink. The first circuit board 23 extends vertically up and down and faces the front and rear. The second circuit board 24 extends horizontally left and right and faces the top and bottom.

[0029] Referring to Figure 4 、 5, 6, the light emitting unit 3 includes five first light emitting modules 31 disposed at the front end of the first circuit board 23, and seven second light emitting modules 32 disposed at the bottom end of the second circuit board 24. Since the first light emitting modules 31 are identical to each other, and the second light emitting modules 32 are identical to each other, in the following description, one of the first light emitting modules 31 and one of the second light emitting modules 32 will be taken as representatives for description.

[0030] The first light emitting module 31 and the second light emitting module 32 can respectively project several first light rays L11 (see Figure 8 ) and several second light rays L12 (see Figure 9 ) forward or downward toward the optical lens 4. Among them, both the first light emitting module 31 and the second light emitting module 32 emit light using LED chips. As for the traveling modes of the first light rays L11 and the second light rays L12 respectively generated by the first light emitting module 31 and the second light emitting module 32, they will be described after the optical lens 4 is completely described.

[0031] The optical lens 4 includes five first light output lens parts 41 integrally connected to each other left and right, a plurality of first light input lens parts 42 corresponding to the number of the first light output lens parts 41 and respectively integrally connected to the rear ends of the first light output lens parts 41, seven second light input lens parts 43 connected to the top ends of the first light output lens parts 41, and a plurality of second light output lens parts 44 corresponding to the number of the second light input lens parts 43 and connected to the bottom ends of the first light output lens parts 41.

[0032] Since the first light output lens parts 41 are identical to each other, the first light input lens parts 42 are identical to each other, the second light input lens parts 43 are identical to each other, and the second light output lens parts 44 are identical to each other, in the following description, one of the first light output lens parts 41, one of the first light input lens parts 42, one of the second light input lens parts 43, and one of the second light output lens parts 44 will be mainly taken as representatives. In addition, since the positions of the third first light input lens part 42 and the fourth second light input lens part 43 are aligned, Figure 6 , 8 , 9 are cross-sectional views through the third first light input lens part 42 and the fourth second light input lens part 43.

[0033] The first light output lens part 41 includes a first light output surface 411 located at the front end and facing forward. The first light output surface 411 protrudes forward from the rear and defines a first focal point F11 (see Figure 8 ) located behind the first light emitting module 31.

[0034] The number of the first light-incident lens parts 42 of the optical lens 4 corresponds to the number of the first light-emitting modules 31 of the light-emitting unit 3. Continuing to take one of the first light-incident lens parts 42 as an example for illustration, and mainly referring to Figure 6 : The first light-incident lens part 42 includes a first end 421 located at the rearmost position, and a first light-gathering space S1 is formed by recessing forward from the first end 421. The first light-gathering space S1 is used for the first light ray L11 (see Figure 8 ) generated by the first light-emitting module 31 to enter the first light-incident lens part 42.

[0035] The first light-incident lens part 42 further includes a first main light-incident surface 422 located in front of the first light-gathering space S1, a first side light-incident surface 423 surrounding the first main light-incident surface 422 and cooperating with the first main light-incident surface 422 to define the first light-gathering space S1, and a first reflecting surface 424 extending forward from the first end 421 to connect to the first light-emitting lens part 41 and surrounding the first light-gathering space S1.

[0036] The first main light-incident surface 422 protrudes from front to back. The first side light-incident surface 423 is annular. The first reflecting surface 424 expands outward from back to front. The first reflecting surface 424 is formed by a part of a line segment of one of the two curves of a hyperbola around a first optical axis A11 (see Figure 6 ), and defines a plurality of first virtual foci V11 arranged in a circle around (see Figure 8 , because Figure 8 is a cross-sectional view, so only two of the first virtual foci V11 located on the cross-section are marked).

[0037] Refer to Figure 5 、 6 、7, each of two of the first reflecting surface 424 includes two first surface segments 424a spaced up and down and extending forward from the first end 421, two second surface segments 424b spaced left and right and extending forward from the first end 421, and a plurality of third surface segments 424c extending forward from the first end 421 and located between the first surface segments 424a and the second surface segments 424b. Each of the third surface segments 424c is discontinuous with the adjacent first surface segments 424a and the second surface segments 424b.

[0038] Refer to Figure 4 、 5 、6, the number of the second light-incident lens parts 43 of the optical lens 4 corresponds to the number of the second light-emitting modules 32 of the light-emitting unit 3. Continuing to take one of the second light-incident lens parts 43 as an example for illustration, and mainly referring to Figure 6The second light-entering lens portion 43 includes a second end 431 located at the top, and forms a second light-collecting space S2 extending downward from the second end 431 toward the first light-emitting lens portion 41. The second light-collecting space S2 is used to receive the second light L12 (see FIG. Figure 9 ) is incident on the second light-entering lens portion 43.

[0039] The second light-entering lens portion 43 also includes a second main light-entering surface 432 located between the second light-collecting space S2 and the first light-emitting lens portion 41 above and below, a second side light-entering surface 433 surrounding the second main light-entering surface 432 and cooperating with the second main light-entering surface 432 to define the second light-collecting space S2, and a second reflecting surface 434 extending from the second end 431 to connect to the first light-emitting lens portion 41 and surrounding the outside of the second light-collecting space S2.

[0040] 6 and 9 , the second main light incident surface 432 is convex from bottom to top and defines a second focus F12 . The second focus F12 overlaps with the second light emitting module 32 , or in other words, the second light emitting module 32 is located on the second focus F12 .

[0041] The second reflective surface 434 expands from top to bottom and is formed by a segment of a parabola around a second optical axis A12. The second reflective surface 434 defines a plurality of parabolic foci F21 arranged in a circle (due to Figure 9 Since it is a cross-sectional view, only two parabola foci F21 located on the cross-sectional surface are indicated.

[0042] The second light emitting lens portion 44 includes a second light emitting surface 441 with a top connected to the bottom of the first light emitting surface 411 and facing forward, and an inclined reflecting surface 442 extending upward and backward from the bottom of the second light emitting surface 441 .

[0043] The second light-emitting surface 441 extends vertically downward from the first light-emitting surface 411 and faces forward. The second light-emitting surface 441 defines an angle A21 of 45 degrees with the inclined reflective surface 442. In other embodiments of the present invention, the angle A21 can also be x degrees, where x is an integer between 40 and 50 degrees.

[0044] The inclined reflective surface 442 includes a plurality of reflective surface portions 443 (see Figure 5)。The multiple reflecting faces 443 are grouped in sets arranged left and right. The reflecting faces 443 of each set are arranged vertically. Each of the reflecting faces 443 is a part of a cylindrical surface. However, since the radius of curvature of the corresponding cylindrical surface is quite large, the curvature of each of the reflecting faces 443 is quite small, so it is difficult to show in the drawings. Among them, the axial direction of each of the cylindrical surfaces is the same as the inclined extending direction of the inclined reflecting surface 442.

[0045] Refer to Figure 6 、 8 、9, then, the traveling modes of the first light ray L11 and the second light ray L12 will be described. Among them, the light traces of the light rays in the air are represented by solid lines, the light traces of the light rays in the lens are represented by dashed lines, and the extended lines after the light rays are refracted / reflected are represented by dotted lines.

[0046] Among the first light rays L11 generated by the first light-emitting module 31, a part of them will enter the first light-incoupling lens part 42 from the first main light-incoupling surface 422 as Figure 8 shown. The extended lines of the first light rays L11 incident on the first main light-incoupling surface 422 intersect at the first focal point F11. That is to say, this part of the first light rays L11 is as if emitted from the first focal point F11 of the first light-emitting surface 411. Therefore, after this part of the first light rays L11 are emitted from the first light-emitting surface 411, they will be substantially parallel to each other.

[0047] Another part of the first light rays L11 generated by the first light-emitting module 31 will enter the first light-incoupling lens part 42 from the first side light-incoupling surface 423. The extended lines of the first light rays L11 incident on the first side light-incoupling surface 423 intersect to form several first virtual focal points V11. Each of the first virtual focal points V11 and the first focal point F11 are the two focal points of the two curves of a hyperbola. Since the optical property of a hyperbola is that the light rays emitted from one of the focal points, after being reflected by the corresponding curve, the extended lines intersect at the focal point of the other curve. Therefore, after this part of the first light rays L11 are reflected by the first reflecting surface 424, the extended lines will intersect at the first focal point F11. That is to say, after this part of the first light rays L11 are refracted by the first side light-incoupling surface 423 and reflected by the first reflecting surface 424, they are also as if emitted from the first focal point F11. Therefore, after this part of the first light rays L11 are emitted from the first light-emitting surface 411, they are also substantially parallel to each other.

[0048] A part of the second light rays L12 generated by the second light-emitting module 32 will enter the second light-incoupling lens part 43 through the second main light-incoupling surface 432. The second light rays L12 incident on the second main light-incoupling surface 432 travel toward the inclined reflecting surface 442 along a projection direction D11 that intersects the front-rear direction horizontally. Since the second light-emitting module 32 is located at the second focal point F12 of the second main light-incoupling surface 432, after a part of the second light rays L12 enter through the second main light-incoupling surface 432, they will be projected downward toward the inclined reflecting surface 442 substantially parallel to each other. That is, in this embodiment, the projection direction D11 is the up-down direction, specifically the up-down direction perpendicular to the front-rear direction. Finally, this part of the second light rays L12, after being reflected by the inclined reflecting surface 442, are emitted forward through the second light-emitting surface 441.

[0049] Another part of the second light rays L12 generated by the second light-emitting module 32 will enter the second light-incoupling lens part 43 through the second side light-incoupling surface 433. The extension lines of the light rays incident on the second side light-incoupling surface 433 intersect at the parabolic focal point F21. That is, after this part of the second light rays L12 are refracted by the second side light-incoupling surface 433, they are as if emitted from the parabolic focal point F21. Therefore, after this part of the second light rays L12 are reflected by the second reflecting surface 434, they will also be projected downward toward the inclined reflecting surface 442 substantially parallel to each other along the projection direction D11, and finally are reflected by the inclined reflecting surface 442 and emitted forward through the second light-emitting surface 441.

[0050] Generally speaking, after the first light rays L11 enter the first light-incoupling lens part 42, they travel forward toward the first light-emitting lens part 41 and are emitted forward through the first light-emitting surface 411. After the second light rays L12 enter the second light-incoupling lens part 43, they travel straight downward through the first light-emitting lens part 41 toward the second light-emitting lens part 44, and after being reflected forward by the inclined reflecting surface 442, they are emitted forward through the second light-emitting surface 441. Moreover, the first light rays L11 do not enter the second light-emitting lens part 44 and are not emitted through the second light-emitting surface 441, and the second light rays L12 are not emitted through the first light-emitting surface 411.

[0051] The characteristics of this embodiment lie in that the first light rays L11 and the second light rays L12 in different directions generated by the first light-emitting module 31 and the second light-emitting module 32 can be respectively emitted forward by the first light-emitting surface 411 and the second light-emitting surface 441 and thus be observed by passers-by. Therefore, the first light-emitting module 31 and the second light-emitting module 32 can be respectively used to provide light rays for different vehicle lamp functions. For example, the first light rays L11 can be used as the light rays of the main lamp, and the second light rays L12 can be used as the light rays of the running lamp or the turn signal lamp, so that this embodiment has at least two different vehicle lamp functions at the same time.

[0052] Furthermore, since this embodiment actually includes a plurality of first light-emitting modules 31, a plurality of first light-incident lens parts 42, and a plurality of first light-emitting lens parts 41, a part of the first light rays L11 can be designed to generate light rays for the high beam, and another part of the first light rays L11 can be designed to generate light rays for the low beam. Similarly, since this embodiment actually includes a plurality of second light-emitting modules 32, a plurality of second light-incident lens parts 43, and a plurality of second light-emitting lens parts 44, a part of the second light rays L12 can be designed to generate light rays for the running lamp, and another part of the second light rays L12 can be designed to generate light rays for the turn signal lamp. Therefore, this embodiment can even have more than four different vehicle lamp functions. Among them, the advantage of each of the inclined reflecting surfaces 442 including a plurality of reflecting parts 443 is that the light rays can be diverged during reflection, so that the second light rays L12 can meet the regulatory requirements after divergence.

[0053] In summary, the beneficial effect of the vehicle lamp device of the present invention is that the first light-emitting module 31 and the second light-emitting module 32 can project the first light rays L11 and the second light rays L12, and the first light rays L11 and the second light rays L12 can finally be emitted forward by the first light-emitting surface 411 and the second light-emitting surface 441 that face forward and have different positions and thus be observed by passers-by. Therefore, the present invention has the characteristic of having at least two of a variety of vehicle lamp functions such as high beam / low beam / turn signal lamp / running lamp by using the first light rays L11 and the second light rays L12.

[0054] The above is only the specific implementation manner of the present invention and cannot be used to limit the scope of the claims of the present invention. Moreover, equivalent change patterns made according to the recorded content of the claims and the description of the present invention should also be covered by the scope of the claims of the present invention.
