Problems solved by technology

[0005] In the case where the above-mentioned components are provided with the light guide reflector described in the above-mentioned Patent Document 1, due to the light guide reflector in Patent Document 1, the reflection surface of the light guide reflector faces rearward at the front position of the main reflector. Therefore, it is difficult to release the light guide mirror of Patent Document 1 in the direction of the optical axis of the main light-emitting part.

no. 1 Embodiment approach

[0039] figure 1 It shows the front view of the two-wheeled motorcycle equipped with the headlight illuminator which concerns on 1st Embodiment of this invention.

[0040] The motorcycle 10 has a front cover 11 covering the front of the vehicle body, and a front side cover 12 formed of a pair of left and right sides provided on the front cover 11 and covering the left and right sides of the front of the vehicle body. A single headlight illuminator 21 that illuminates the front of the vehicle body is provided at an intermediate position in the vehicle width direction of the front cover 11 , and turn signal lamp units 13 are provided on the left and right front side covers 12 , respectively.

[0041] The front illuminator 21 has: a front surface lens 22 covering the front surface of the illuminator 21; and a lamp cover 25 located behind the front surface lens 22 and supporting a single bulb 23 formed as a light source on the lamp cover 25. and between the front surface lens 22. ...

no. 2 Embodiment approach

[0099] Figure 5 It is a front view showing the front illuminator 21 and its peripheral structure of the second embodiment. In this figure, with the above figure 2 Likewise, the middle region of the front lens 22 (the region corresponding to the middle region AR1 ) is removed. in addition, Figure 6 means along Figure 5 A cross-sectional view cut along line VI-VI. In addition, in Figure 5 , Figure 6In each figure described below and below, the same structures as those of the first embodiment are denoted by the same symbols, and only the different parts will be described here.

[0100] Such as Figure 5 and Figure 6 As shown, in the second embodiment, the left and right first sub-reflectors 28 are located behind the bulb 23, and are arranged in an area where the light emitted backward by the bulb 23 (filament 23A for low beam) can be irradiated, and form a It is a shape that can be released from the mold in the front-rear direction α, and it faces the opening 27K ...

no. 3 Embodiment approach

[0116] Figure 7 It is a side view showing the front illuminator 21 and its peripheral structure of the third embodiment. In the third embodiment, a case where the first sub-mirror 28 is integrally formed with the movable mirror-type main mirror 27 will be described. In this configuration, the first sub-mirror 28 and the second sub-mirror 29 are integrally provided with the main mirror 27, which is a movable movable mirror capable of adjusting the optical axis.

[0117] The position of the swing axis 27J of the main mirror 27 is set such that the positions of both the first and second sub mirrors 28 and 29 are moved to appropriate positions corresponding to the position change of the main mirror 27 . In this structure, by setting the swing shaft 27J at Figure 7 The position shown (located above the first sub-reflector 28 and behind the main reflector 27), when the main reflector 27 is moved to adjust the optical axis of the main light-emitting part 41, the first sub-reflect...

Abstract

The present invention provides an illuminator capable of easily releasing a sub-reflector in the direction of the optical axis of a main light-emitting part. The direction of the emitted light direction of the part is reflected. The illuminator also has a first secondary reflector (28) that reflects a part of light from the bulb (23) in a direction different from the direction of reflected light from the main reflector (27). The first sub-reflector (28) is arranged behind the bulb (23), and is located in an area where the light irradiated backward can be irradiated, and is formed so as to follow the light of the main light emitting part (41) in this arranged state. A shape that can be released from the mold in the axial direction (front-back direction α).

Description

technical field [0001] The invention relates to a luminaire with a main light emitting part and a secondary light emitting part. Background technique [0002] Two-wheeled motorcycles and the like disclosed in the prior art have a structure that forms an illuminator having a feature of performing spectral processing on light from a light source for a main light emitting unit). This type of illuminator is provided with: a main reflector, which reflects the light of the light source of the main light emitting part forward; a light guide reflector, which is connected to the upper front end of the main reflector; a side reflector, which is connected to the main reflector The lower front end of the reflector. A part of the light emitted from the bulb as the light source for the main light emitting unit is reflected downward by the light guide reflector, and the light is reflected forward by the side reflector (for example, refer to Patent Document 1). [0003] Patent Document 1:...
