Specific embodiment

Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.? In specification, identical drawing reference numeral indicates component functionally identical or similar.Reality of following reference attached drawings to the utility model The explanation for applying mode is intended to explain the overall utility model design of the utility model, and is not construed as practical to this A kind of novel limitation.

In addition, in the following detailed description, to elaborate many concrete details to provide to present disclosure convenient for explaining The comprehensive understanding of embodiment.It should be apparent, however, that one or more embodiments without these specific details may be used To be carried out.

Fig. 1 and Fig. 2 schematically shows a kind of optical module 100 for car light.As shown in Fig. 2, the optical module 100 Including：Light source module 1 and transparent light guide block 2.The light source module 1 is used to issue incident beam 3 to transparent light guide block 2.This is transparent Guide-lighting block 2 includes light incident surface 10, light-emitting face 20, the first lateral reflection face 31 and second side reflecting surface 32.First lateral reflection face 31 and second side reflecting surface 32 it is positioned opposite to each other, and extend between light incident surface 10 and light-emitting face 20.The light is incident The arrangement of face 10 is for receiving the incident beam 3 issued from the light source module 1.The light-emitting face 20 is arranged in incident with the light The opposite side in face 10, for exporting outgoing beam 4.And the first lateral reflection face 31 and second side reflecting surface 32 be then arranged to by from The incident incident beam 3 of light incident surface 10 is conducted in a manner of total reflection to light-emitting face 20.In basis as illustrated in fig. 1 and 2 In the optical module 100 of the embodiments of the present invention, light incident surface 10, light-emitting face 20, the first lateral reflection face 31 and second Lateral reflection face 32 can be smooth surface.

In the prior art, the adjustment of the range of exposures of the outgoing beam of car light and light distribution is usually each by being laid with The light distribution surface of convex-concave structure is planted to realize.But this light distribution surface often makes the outgoing beam of car light give numerous and disorderly visual impression By.And the optical module of embodiment according to the present utility model uses the smooth transparent light guide block in surface, can meet out That car light is improved in the case where the range of exposures and light distribution of irradiating light beam lights effect.

Fig. 3 to Fig. 6 shows the beam portion being emitted in different directions in optical module according to the present utility model The example divided.The beam section being emitted in optical module 100 towards front is shown in FIG. 3, and this segment beam is for example It may come from the beam section perpendicular to light incident surface 10 issued from light source module.Optical module 100 is shown in FIG. 4 In towards the beam sections for deflecting 20 degree of outgoing to the right relative to front, and this segment beam for example may come from from light source The beam section of the side wall for the directive transparent light guide block that module issues.Be shown in FIG. 5 in optical module 100 towards relative to Front deflects to the right the beam section of 40 degree of outgoing, and this segment beam for example may come from and penetrate from what light source module issued To the beam section of the side wall of transparent light guide block.It can be seen that by comparison diagram 4 and Fig. 5 for example shown in Fig. 5, from At the more top position of the side wall for the light beam directive transparent light guide block that light source module issues.Optical module is shown in FIG. 6 In 100 towards deflected to the right relative to front 60 degree outgoing beam sections, and this segment beam for example can be from The beam section of the side wall of the directive transparent light guide block issued from light source module, but the example of Fig. 5 is compared, it is sent out from light source module At the more top position of the side wall of light beam directive transparent light guide block out.In the example shown in fig. 4 to fig. 6, transparent light guide The side wall of block can at least partly be totally reflected incident beam, so that light beam be enable to be emitted from biggish range.

For clarity of illustration, in Fig. 3 into Fig. 6, light beam is represented by the dotted line, and for the light beam of different exit directions Part is shown respectively, and illustrate only reflex of the side wall for light beam of transparent light guide block, and in practice, These beam sections are included in outgoing beam, and at least two side walls (31 He of such as the first lateral reflection face of transparent light guide block Second side reflecting surface 32) all there is similar reflex to light beam.Therefore, the outgoing beam of transparent light guide block can cover compared with Big outgoing range, for example, at least 120 degree of range.At the same time, due to using smooth saturating in surface in the optical module 100 Bright leaded light block realizes the exit direction of adjustment to(for) light beam, therefore, even if observer can also also see in beam exit To exquisitely carved display effect as " ice cube ".Since the side of transparent light guide block carries out anti-light beam substantially in the form of total reflection Penetrate, therefore, from the side of transparent light guide block go out light can be fewer, it might even be possible to ignore.Then, observer can clearly thoroughly See the object blocked by transparent light guide block in the side for crossing transparent light guide block.

As an example, normal (the dotted line in such as Fig. 2 of the first lateral reflection face 31 and second side reflecting surface 32 and light incident surface 10 It is shown) angle α be more than or equal to 0 degree and less than or equal to 10 degree.This is conducive to that the first lateral reflection face 31 and second is better achieved Guiding function of the lateral reflection face 32 for incident beam.

As an example, the first lateral reflection face 31 and second side reflecting surface 32 can be vertical with light incident surface 10, it can also phase The normal of the light incident surface 10 is tilted in opposite direction, as shown in Figure 2.It is anti-in the first lateral reflection face 31 and second side In the case where penetrating normal slope of the face 32 relative to the light incident surface 10, for example, the first lateral reflection face 31 and the second lateral reflection The angle α of the normal of face 32 and light incident surface 10 is no more than 10 degree.

In the embodiments of the present invention, all outer surfaces of transparent light guide block 2 can be smooth surface.Although Transparent light guide block 2 is described by taking the first lateral reflection face 31 and second side reflecting surface 32 as an example in above-mentioned example, still, In the embodiments of the present invention, the number in the lateral reflection face of transparent light guide block 2 is not limited to two, such as can be four, six It is a or more.Correspondingly, transparent light guide block 2 can have cross section of various shapes, such as quadrangle, hexagon.
