Integral light guide 3.
Fig. 2 is the schematic diagram of the light-emitting device for motor vehicles according to another embodiment of the present utility model, Fig. 2
The difference of shown embodiment and the embodiment shown in Fig. 1 is essentially consisted in：In Fig. 2, transposition section and straightway out of plumb.
In figure, the axis of the transposition section points to the direction of secondary light source component 2 and points to the first light source group with the axis of the straightway
First jiao of A is formed between the direction of part 1, the dichroic coating 35 is arranged on the infall of straightway and transposition section, the dichroic coating
Plane where 35 and second jiao of B is formed between the plane of the axis of straightway, and first jiao of A half and the
Two jiaos of B sums are equal to 90 degree.Remain able to ensure by this set to come from the first light source group transmitted through the dichroic coating 35
The light of part 1 and the parallel light from secondary light source component 2 reflected through the dichroic coating 35, so that the two can be mixed.Due to
Two kinds of functional modules are integrated in a light-emitting device, the light-emitting device of vehicle obtains less volume, when foregoing first
When angle is acute angle, straightway and transposition section are more pressed close to, thus the overall volume of light-emitting device is smaller.Preferably, first jiao of A is small
In 30 degree.
Further, under design of the present utility model, light-emitting device of the present utility model can include more than two
Light source assembly, correspondingly, light guide include more than one transposition section, more than two dichroic coating and more than two collimation
Device.For example including three light source assemblies, light guide includes a straightway and two transposition sections, and two transposition sections are respectively in straight line
Section diverse location intersect from straightway (can with different angular cross, but remain first jiao of A half and second jiao
B sums be equal to 90 degree), and infall arrange different qualities dichroic coating, three light source assemblies correspond respectively to straightway with
Two transposition section arrangements.The dichroic coating of the different qualities can be the light of different colours to occur transmission, reflection effect difference,
For example increase dichroic coating on the basis of Fig. 1 and 2 embodiment, it has transmission to white light (champac mixes) and gold-tinted
Property, and there is reflectivity to red light (now, the 3rd light source assembly is configured to launch red light).In this case, phase
For Fig. 1 and 2 embodiment, light-emitting device can also launch pink colour light (mixing of white light and red light), the pink colour light example
Such as play role in decoration, therefore enrich the function of light-emitting device, also enrich design for aesthetic.
Position lamp and steering indicating light may be constructed such that according to light-emitting device 100 of the present utility model, or are configured to down
Car light and steering indicating light.I.e. when in vehicle light-emitting device used above, it is used as position lamp and steering indicating light, works as transmitting
Use, used during transmitting white light as position lamp as steering indicating light during yellow fluorescent lamp, similarly, filled when being lighted in vehicle back using this
When putting, it is used as back-up lamp and steering indicating light, is used when launching yellow fluorescent lamp as steering indicating light, as during transmitting white light
Car light is used.
According to other side of the present utility model, it is possible to use the composite construction illuminating module of light-emitting device, such as Fig. 4-6
Shown illuminating module 200 includes multiple light-emitting devices 100 for being previously described for motor vehicles, and multiple light-emitting devices 100 are arranged
Circularize.Thus, it is possible to be lit and control lighting for light-emitting device 100 by the light-emitting device for controlling regional area 100
Sequentially, what generation was different lights effect.It should be noted that the hair of the construction of the embodiment different from Fig. 4-6 can also be constructed
Optical mode group.
For to further improvement of the utility model, collimater 31 may be constructed such that including two auricles, at two
Opening is formed between auricle, and preferably, the first light source assembly and secondary light source component can be arranged in the opening of collimater
In, so, space on the one hand can be saved, and on the other hand, compared to the collimater of the curved surface structure collimater with higher
Light collection efficiency.For example, with reference to accompanying drawing 7a-8e, for the collimater of curved surface structure, the angle of the light of collimater can be entered
Degree is limited, and for including the collimater of two auricles and opening, a part of light is emitted directly toward the centre between two auricles
Part, a part of light is injected from a face of auricle and reflected on the other surface, so, can to realize collimation
It can be injected with the light for predicting greater angle scope in collimater, thus with higher light collection efficiency, particularly in light
In the case that source component is arranged in the opening of collimater.
Further, two auricles of collimater are flexible, can clamp the first light source assembly or secondary light source component,
So as to remove the fixing device of light source assembly from, and the fast assembling-disassembling and more of light source assembly can be realized by gripping
Change.As an alternate embodiment, two collimaters 31 in the light guide 3 of light-emitting device 100 may be constructed such that one, and
Light shield layer is set to avoid interfering for light between them.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that to be changed these embodiments in the case where not departing from principle of the present utility model and spirit.This practicality
The new scope of application is defined by the appended claims and the equivalents thereof.
