On.For this purpose, bracket 2 has corresponding cooperation location structure.Illustratively, location structure and cooperation location structure can be in convex
It rises and location hole, latch portion or other suitable forms.In the illustration of FIG. 1, side is equipped with positioning protrusion to light conducting piece 3 at one end
301, it is inserted into the location hole 201 for the corresponding position that bracket is set, the size of positioning protrusion and location hole matches each other.
In order to realize the firm fixation of long light conducting piece 3, locking plate 304 is set also on the ontology of light conducting piece 3, on bracket 2
It is provided with lock tongue 204, locking plate 304 and the combination of lock tongue 204 form a form of latch portion, and lock by the way that lock tongue to be inserted into
Lock is realized in the hole of piece.Certainly, the correlation of the opposed two sides of light conducting piece 3 can be arranged in latch portion in a manner of other
Position.
Alternatively, opening 203 can be also provided at the wall in the left side of second support section 22.Light conducting piece 3 it is another
End side can be inserted into the opening 203.Here, the size of opening 203 is at least substantially equivalent to the diameter of light conducting piece 3.Pass through
This mode realizes more reliable light guide positioning in combination with the above-mentioned one end of light conducting piece 3 and the positioning of outer body.This
Outside, since the another side of light conducting piece 3 passes through opening, the cradle wall equipped with opening can also be hidden the light issued from end side
Gear, to realize the light-out effect more evenly of light out part relevant to light conducting piece 3 position.
First support section 21 can have the receiving recess 202 for light conducting piece 3.The length for accommodating recess 202 extends
Length extension with light conducting piece 3 matches.The receiving recess 202 shown extends with curved length.In first support area
The cooperation location structure for light conducting piece 3 in section 21 may be provided in two edges of the open side for accommodating recess extremely
At one few.
Second light source sub-component 5 can be in the form of printed circuit board, the printing electricity with light source 51 and installation light source 51
Road plate 52.Four light sources 51 are shown in FIG. 1, they are all Light-emitting diode LED.The color of light source can be according to actual needs
It selects, such as selects White LED, yellow led or red LED.From the point of view of perpendicular to the direction of the map sheet of Fig. 1, second light source
Sub-component 5 is arranged in the back side of the one side wall of second support section 22, thus prevents externally visibly second light source sub-component 5.
For this purpose, second support section 22 is equipped with aperture 225.Distribute to the light source of second light source sub-component 5 in aperture.It can be seen that in Fig. 1,
Respectively it is furnished with a light source 51 in 4 apertures 225.
Herein it should be mentioned that the second light source sub-component 5 herein proposed is particularly suitable for such situation: due to second
The width of bracket section 22 is significantly wider than first support section 21, is difficult to realize become by the way that an individual light conducting piece 3 is arranged
Uniformly light effect in section light out part position.
Shape of the cross section of second support section 22 with approximate V-arrangement and there is recess 220.It can be seen in Fig. 1
Out, second support section 22 has the bottom of triangle.Second light source sub-component 5 is arranged in the left side of second support section 22
At wall.The face 222 towards light source of the wall on the right side of second support section 22 is fully reflecting surface.The light of second light source sub-component
Other than a part is directly emitted towards light out part position, some is reflected through face 222 towards light out part position the light that source issues.
Compared to the second support section of the cross section in concave shape, in the bottom that light source is wherein arranged in second support section, In
This scheme proposed is able to achieve light-out effect more evenly.
The same settable positioning mechanism as mentioned above on second support section 22, to realize that bracket itself is fixed
On position to other holding meanss.
All components mentioned above can be covered by unshowned the cover, and the cover is by transparent or semitransparent material structure
At and form the light out part position.Therefore, the general outline of the cover and the profile of bracket match, the two can by welding,
The modes such as clamping are fixed together.
Fig. 2 shows another schematical diagrams of light emitting device 1.The structure of the light emitting device 1 is substantially similar to hair
The structure of electro-optical device 1 ' can refer to explanation above to this.Hereafter only illustrate the difference of light emitting device 1.
Due to L-shaped brackets 2, occur mutable site A (referring to Fig. 1) between its two bracket sections, such as two branch
Angle α between the principal spread direction of frame section is less than or equal to 90 degree, occurs the transition face of two bracket sections of connection thus
223, to realize desired moulding.The transition face 223 can be the side wall a part to form fully reflecting surface 222.In second light source
When the light emission that the light source of component 5 issues is to fully reflecting surface, it is easy to form shadow at the light out part position for distributing to transition face 223
Line.Specifically, forming shadow line in the corner for forming light out part position.This is unfavorable for uniform light-out effect.
For this purpose, light emitting device 1 also has intermediate light distribution element 7, which is arranged in second light source sub-component 5
Between housing 6, to be diffused to light.The equally at least partly light transmission of intermediate light distribution element 7, and its surface can be set
There are the miniature diffusing structure in array structure form, such as pillow dermatoglyph or striped.Alternatively, it can be added in intermediate light distribution element
There are scattering particles.So that the light from second light source sub-component 5 must initially pass through scattering before the outgoing of light out part position
The intermediate light distribution element 7 of property, at least to weaken shadow line caused by the reflection particularly because of transition face 223.
Intermediate light distribution element 7 can be plate-like, and the aperture 225 of the light source 51 of second light source sub-component 5 is distributed in covering.In
Between light distribution element 7 grab 706 is equipped at its outer rim, which is caught in the through hole being arranged in the wall of second support section
In 206, to realize the fixation of intermediate light distribution element 7.
In another arrangement, transition face 223 can be diffusing reflection face.Transition face 223 can for example be implemented through coarse processing thus
At scraggly face.Certainly, the transition face 223 of the diffusing reflection of other forms is also feasible.
It can be seen that in Fig. 2, the cover 6 is linked together by connecting location structure 601,602 with bracket 2.Connection positioning
The position of structure and quantity are set in scheduled position as needed.
Above-mentioned light emitting device can be used for car light, such as the luminous color of the light source assembly according to selection, and light emitting device can
For back-up lamp, Brake lamp, turn signal etc..
The utility model is not limited to above structure, can also be using other various variants.Although having passed through Finite Number
The embodiment of amount describes the utility model, but benefits from the disclosure, and those skilled in the art, which can be designed that, not to be departed from
The other embodiments of the protection scope of the utility model disclosed herein.Therefore, the protection scope of the utility model should only by
