The second main light incident surface 432 has a center portion protruding upwardly in the up-down direction, and has a second focal point (F12) (see
Further referring to
The second light exit lens portion 44 has a second light exit surface 441 having a top end that is connected to the lower portion of the first light exit lens portion 41 and facing forwardly in the front-rear direction, and an inclined reflective surface 442 extending inclinedly and rearwardly in the front-rear direction from a lower end of the second light emit surface 441 that is opposite to the first light exit surface 411.
The second light exit surface 441 extends vertically from the first light exit surface 411 in the up-down direction, faces forwardly in the front-rear direction, and cooperates with the inclined reflective surface 442 to define an angle (A21) ranging from 40 degrees to 50 degrees therebetween. In this embodiment, the angle (A21) is 45 degrees. It should be noted that the angle (A21) may be an integer ranging from 40 to 50.
The inclined reflective surface 442 includes a plurality of reflective surface portions 443 (see
Referring to
As shown in
Another portion of the first light rays (11) that are emitted from the first light emitting module 31 propagate into the first light entry lens portion 42 through the first bordering light incident surface 423. Extension lines of the another portion of the first light rays (11) incident on the first bordering light incident surface 423 extend through a plurality of first imaginary focal points (V11). Each of the first imaginary focal points (V11) and the first focal point (F11) are two focal points of a hyperbola. Since the reflecting property of a hyperbola is that extension lines of light rays that are emitted from one of the focal points of the hyperbola being reflected by a branch of the hyperbola that has the one of the focal points, i.e., a half of the hyperbola, extend through another one of the focal points of the hyperbola, the extension lines of the another portion of the first light rays (11) reflected by the first reflecting surface 424 extend through the first focal point (F11). That is to say, extension lines of the another portion of the first light rays (11) incident on the first bordering light incident surface 423 and reflected by the first reflecting surface 424 extend through the first focal point (F11) and are deemed to be emitted from the first focal point (F11) of the first light exit surface 411, and propagate outwardly of the first light exit lens portion 41 via the first light exit surface 411 as parallel light rays.
Referring to
Another portion of the second light rays (L12) that are emitted from the second light emitting module 32 propagate into the second light entry lens portion 43 through the second bordering light incident surface 433. Extension lines of the another portion of the second light rays (L12) incident on the second bordering light incident surface 433 extend through the focal points (F21). That is to say, extension lines of the another portion of the second light rays (L12) incident on the second bordering light incident surface 433 and reflected by the second reflecting surface 434 are deemed to be emitted from the focal points (F21), travel as parallel light rays in the projecting direction (D11) toward and are reflected by the inclined reflective surface 442, and propagate forwardly and outwardly of the second light exit surface 441.
As a whole, the first light rays (11) sequentially enter the first light entry lens portion 42, travel forwardly toward the first light exit lens portion 41, and project forwardly and outwardly from the first light exit surface 411, and the second light rays (L12) sequentially enter the second light entry lens portion 43, travel downwardly through the first light exit lens portion 41 to the second light exit lens portion 44, are reflected by the inclined reflective surface 442, and project forwardly and outwardly from the second light exit surface 441. The first light entry lens portion 42 is configured such that the first light rays (L11) do not pass by the second light exit lens portion 44 and do not be emitted from the second light exit surface 441. The second light entry lens portion 43 is configured such that the second light rays (L12) do not be emitted from the first light exit surface.
Some features of the embodiment reside in the following. By virtue of the configuration of the optical lens 4, the first light rays (L11) and the second light rays (L12) emitted respectively by the first light emitting module 31 and the second light emitting module 32 in different directions are reflected and project forwardly from the first light exit surface 411 and the second light exit surface 441 in the front-rear direction to be seen by a road user. As such, the first light emitting module 31 and the second light emitting module 32 may respectively provide lights rays having different vehicle lighting functions. For example, the first light rays (L11) may serve as light rays of a headlamp, and the second light rays (L12) may serve as light rays of a daytime running lamp or turn signals. In this way, the embodiment of the present disclosure provides two different vehicle lighting functions.
In addition, since the vehicle light device of the present disclosure includes the plurality of first light emitting modules 31, the plurality of first light entry lens portions 42, and the plurality of first light exit lens portions 41, a portion of the first light rays (11) may be employed to serve as high beams, and another portion of the first light rays (11) may be employed to serve as low beams. Similarly, since the vehicle light device of the present disclosure includes the plurality of second light emitting modules 32, the plurality of second light entry lens portions 43, and the plurality of second light exit lens portions 44, a portion of the second light rays (L12) may be employed to serve as light rays of a daytime running lamp, and another portion of the second light rays (L12) may be employed to serve as turn signals. In this way, the embodiment provides various vehicle lighting functions. Furthermore, the advantage of each inclined reflective surface 442 including a plurality of reflective surface portions 443 resides in that the second light rays (L12) may be distributed evenly by the reflective surface portions 443 so that the second light rays (L12) exited from the second light exit surface 441 comply with regulations.
In summary, the advantages of the vehicle light device according to the present disclosure reside in the following. The first light rays (11) and the second light rays (L12) emitted respectively by the first light emitting module 31 and the second light emitting module 32 exit respectively and forwardly from the first light exit surface 411 and the second light exit surface 441 in the front-rear direction and may be seen by a road user. Thus, the vehicle light device provides lights rays having various vehicle lighting functions such as a headlamp with high beams and low beams, a daytime running lamp, and turn signals.
