This is surging.Certainly can also avoid the assembling operation of front lamp device 46 becomes the complicated and increased situation of process number.
In the case where light shielding part 112 shows color, also with above-mentioned like that as the headlamp dress that design is superior
Advantage as putting 46.
On the other hand, for example in night running around in the absence of in the case of pedestrian, opposite car and front truck, it is desirable to carry
High visibility.Therefore, in this case, passenger operation is cut for switch, by the control of the control unit by distance light LED104
Light and extinguish dipped beam LED106.That is, distance light is irradiated by front lamp device 46.
Now, as shown in figure 4, distance light with the direct light in the emergent light of LED104, being directly toward distance light through portion 132 and
Reflected light after being reflected by distance light reflecting part 122 is reduced or directly constitutes distance light in the case of blocking not being blocked portion 112.
As shown in Figures 4 and 5, in front lamp device 46, dipped beam through portion 134 is arranged to be leaned on than distance light through portion 132
Rear.In addition, in space 116, it is straight with being accompanied between LED104 and distance light reflecting part 122 and dipped beam through portion 134 in distance light
The substrate 118 of wire portion 136 and light-proofness.Therefore, it is possible to prevent the direct light and distance light reflecting part 122 of distance light LED104
The situation that reflected light is irradiated towards dipped beam through portion 134.
Therefore, it is possible to not reducing or being utilized in the case of blocking distance light with the emergent light of LED104.That is, can
Effectively utilize distance light and obtained with the emergent light of LED104 the distance light of enough luminous intensities.
As previously discussed, in front lamp device 46, by reduce or block in night running with opposite car or walking
Person staggers and the direct light of the out-of-date dipped beam lighted LED106, thus, it is possible to effectively prevent dizzy puzzled situation.It is another
Aspect, requires that the distance light of strong luminous intensity is not reduced with the emergent light of LED104 or blocked and direct compared with dipped beam
Utilize such that it is able to obtain the distance light of enough luminous intensities.
That is, in front lamp device 46, it is possible to increase dipped beam LED106 and the respective emergent lights of distance light LED104
Utilization ratio, simultaneously effective prevents from making opposite car or pedestrian produce dizzy puzzled situation.
In addition, in front lamp device 46, the direct of dipped beam LED106 can be reduced by light shielding part 112 or blocked
