Include extension, vertical section and the linkage section between vertical section and extension in light shielding part 5, therefore light shielding part 5 can be complete
Light source 1 arranged up and down and the first light guide section 2 are blocked, so that would not observe that them from outside.
The light beam of the light emitting device for motor vehicles of 2 explanation first embodiments according to the present invention with reference to the accompanying drawing
Propagation path.Firstly, light source 1 emits light beam B towards the first incidence surface 21, light beam B enters the after the refraction of the first incidence surface 21
One light guide section 2 and directive reflecting surface 23, then light beam B is reflected towards the first light-emitting surface 22 by reflecting surface 23, in the first light-emitting surface 22
Upper light beam B is reflected, later the second incidence surface of directive 31 and the second light guide section 3 of entrance, and subsequent light beam B is in the second light-emitting surface
It is projected on 32.
As an example, reflecting surface 23 can have the convex surface of convex, the light beam B of such directive reflecting surface 23 is in reflecting surface
Certain convergent effect can be generated on 23, therefore the light beam of the diverging (non-parallel) emitted by dotted light source 1 can be anti-through this
The reflection for penetrating face 23 becomes collimated light beam.
In the first embodiment, it is provided with optical scattering structure 33 on second light-emitting surface 32, as shown in figure 3, being used for
The light beam being emitted through the second light-emitting surface 32 is diffused.Additionally, which, which also can be set, enters light first
Face 21, the first light-emitting surface 22, reflecting surface 23, on the second incidence surface 31.
Optical scattering structure is set on incidence surface, light-emitting surface, reflecting surface (especially the second light-emitting surface), so that light beam is more equal
Even, the beam intensity that the second light-emitting surface that external observer sees issues is consistent, and observation brightness from different perspectives is also consistent,
Therefore visual effect is more preferable.
For the variation in the section of generation light-guide device, first embodiment is using the first light guide section 2 and the second light guide section 3
In conjunction with scheme, further, light-guide device can also include third light guide section, and third light guide section setting is in the first leaded light
Between portion 2 and the second light guide section 3, and the area of section perpendicular to propagation path of third light guide section is greater than the second leaded light
The area of section perpendicular to propagation path in portion, but it is less than the cutting perpendicular to propagation path of the first light guide section 2
Face area, that is to say, that the variation in the section of light-guide device can be realized by three light guide sections, in this way it is possible to real
Now bigger area of section changes ratio, therefore can obtain richer shape-designing, and the light-emitting surface of light emitting device (i.e.
Second light-emitting surface 32 of the second light guide section 3) at area can be smaller, it might even be possible to form the luminous pattern of linear.Equally
Ground, the third light guide section can have along the section face perpendicular to propagation path that propagation path gradually limits
Product, alternatively, the third light guide section also can have along the reduction of propagation path phase step type perpendicular to propagation path
Area of section.
Further, in the first embodiment of the present invention, and only shell 4 be located at the first light guide section 2 and second
Reflecting layer is set on part between light guide section 3, to avoid light loss, the light beam being emitted in this way through the first light-emitting surface 22 is mapped to shell
Part on body 4 can be reflected on the second incidence surface 31 of the second light guide section 3.
Fig. 4 is the schematic diagram according to the light emitting device for motor vehicles of the second embodiment of the present invention, it illustrates
The technical solution different from the first embodiment of the present invention, the difference is that: first light guide section 2 has the first incidence surface
21 and first light-emitting surface 22 opposite with the first incidence surface 21, the first incidence surface 21 be the concave surface for forming inner fovea part, and it is described
Light source 1 is contained in the inner fovea part or arranges adjacent to the inner fovea part.What the concave surface of the first incidence surface 21 emitted light source 1
Light beam is gathered, and light efficiency is improved.
It further, can also include optical collimator between light source 1 and the first light guide section 2, for emit light source 1
Light beam B collimation.The setting of optical collimator can play the role of expanding the light-emitting area of light source 1, for example, when light source 1 is point light
When source, optical collimator can convert it into area source.Be conducive to light beam in this way into the first light guide section 2, improve light using effect
Rate.As an example, optical collimator 50 can be lens or any suitable device that can be realized optical alignment in the prior art.
Fig. 5 is the schematic diagram according to the light emitting device for motor vehicles of the third embodiment of the present invention.It is shown in Fig. 1
First embodiment in, first light guide section 2 and the second light guide section 3 are configured to element independent of each other.Unlike this, exist
In 3rd embodiment, first light guide section 2 and the second light guide section 3 are configured to the one to link together by interconnecting piece 6
Molding element.Interconnecting piece 6 can be significantly less than along the area of section perpendicular to propagation path to be plate-shaped or strip-shaped
The area of section perpendicular to propagation path of first light guide section 2 and second light guide section 3.In this way, described
Gap is formed between one light guide section 2 and the second light guide section 3, to be formed twice on the first light-emitting surface 22 and the second incidence surface 31
Refraction.
Further, reflecting layer can be set on the upper surface of interconnecting piece 6, in this way, through the first light-emitting surface 22
The part that the light beam of outgoing is mapped on the upper surface of interconnecting piece 6 can be reflected on the second incidence surface 31 of the second light guide section 3,
To avoid light loss.Interconnecting piece 6 is also constructed with multiple through-holes or slot, to mitigate weight.
