On the other hand, the mirror cells 20 constituting the vertical first mirror cell group 10AH and the horizontal first mirror cell group 10AW do not have to swing, for example, but in this embodiment, the mirror cells 20 that can constitute the second mirror cell group 10B Similarly, it can be swung.

Hereinafter, an example of a specific configuration of the mirror cell 20 will be described.
For example, as shown in FIGS. 4 and 5, the mirror cell 20 is supported so as to be swingable with respect to the base portion 21, and a mirror plate 22 that reflects light from the light source portion 4 in a predetermined direction. Is provided.
The mirror plate 22 has a flat reflecting surface 22A. The mirror plate 22 can swing in any direction with respect to the base portion 21. The mirror plate 22 may be formed in an arbitrary plan view shape, but in the present embodiment, it is formed in a rectangular shape in plan view.

The configuration of the base portion 21 may be arbitrary, but the base portion 21 of the present embodiment is provided on a plate-like base main body 23 and a main surface 23A of the base main body 23, and the mirror plate 22 is attached to the base main body 23. And a support portion 24 that supports the main surface 23A so as to be swingable at a position spaced above the main surface 23A.
The base body 23 is an insulating material formed in a substrate or plate shape, for example. The support portion 24 is provided so as to protrude from the main surface 23 </ b> A of the base body 23, and includes a frame portion 25 surrounding the mirror plate 22 and a plurality of beam portions 26 extending from the peripheral edge portion of the mirror plate 22 to the frame portion 25.

The frame portion 25 is formed in a plan view shape corresponding to the mirror plate 22, that is, in the present embodiment, it is formed in a rectangular shape in plan view.
The plurality of beam portions 26 are arranged at intervals in the circumferential direction of the frame portion 25. Each beam portion 26 is formed to be elastically deformable, for example. In this embodiment, each beam part 26 connects the corner | angular part of the mirror board 22 and the corner | angular part of the frame part 25 facing this.
The mirror plate 22, the frame portion 25, and the beam portion 26 can be configured by, for example, a soft magnetic material such as iron or nickel, or a substrate made of a semiconductor. The reflection surface 22A of the mirror plate 22 can be formed by evaporating a metal thin film such as gold or aluminum on the substrate, for example.

  Further, the mirror cell 20 of the present embodiment includes a plurality of electrodes 27 arranged on the main surface 23A of the base body 23 as a configuration for displacing the mirror plate 22 to a desired inclination angle. The plurality of electrodes 27 are arranged at intervals in the circumferential direction of the frame portion 25 in a region facing the mirror plate 22 on the main surface 23 </ b> A of the base body 23. In the present embodiment, the electrodes 27 are arranged at each corner of the mirror plate 22.

In this configuration, when the mirror plate 22 is tilted, for example, a driving potential is applied to some selected electrodes 27 among the plurality of electrodes 27. Further, a ground potential is applied to the mirror plate 22. As a result, an electrostatic attractive force (Coulomb force) is generated between the applied electrode 27 and the portion of the mirror plate 22 positioned immediately above the applied electrode 27. The mirror plate 22 is tilted when the portion of the mirror plate 22 approaches the base body 23 by this electrostatic attraction. Further, by adjusting the magnitude of the drive potential applied to the selected electrode 27, the tilt angle of the mirror plate 22 can be changed, and the mirror plate 22 can be set to a desired tilt angle. Further, the mirror plate 22 can be swung by changing the electrode 27 to which the driving potential is applied.
The change in the tilt angle of the mirror plate 22 in this embodiment (that is, the tilt angle of the mirror cell 20) is controlled by the mirror array control unit 17 described later.

As shown in FIG. 7, the light distribution control unit 5 of the present embodiment includes the above-described mirror array 10 and a mirror array control unit 17 that controls the operation of the mirror array 10.
The mirror array control unit 17 of the present embodiment controls the operation of the mirror array 10 based on the detection result of the state detection unit 18 that detects the state of the vehicle V. The state detection unit 18 includes a switch detection unit 18A that detects at least the state of the blinker switch of the vehicle V and an attitude detection unit 18B that detects the attitude of the vehicle V.

  The switch detection unit 18A detects whether the blinker switch is arranged at a position where the blinker unit 3 blinks or a position where the blinker unit 3 is turned off. There are two positions for blinking the blinker unit 3, left and right, and the switch detection unit 18 </ b> A also distinguishes between these two positions.

Further, the switch detection unit 18A detects whether the lighting switch is arranged at a position where the lighting unit 2 is turned on or a position where the lighting unit 2 is turned off.
In the present embodiment, since the lighting unit 2 includes the first lighting unit 2A and the second lighting unit 2B, the lighting switch includes a main lighting switch for lighting the first lighting unit 2A of the lighting unit 2, and a lighting unit. 2, a sub-light switch for turning on the second light part 2 </ b> B. These main light switch and sub light switch may be integrated, for example, or may be separate, for example. When the main lamp switch and the sub lamp switch are separate, the switch detector 18A detects the positions of the main lamp switch and the sub lamp switch.
A signal indicating the position of the blinker switch or the light switch detected by the switch detection unit 18A is sent to the mirror array control unit 17.

  The posture detection unit 18B of the present embodiment includes a vehicle speed sensor, a handle angle sensor, and a vehicle tilt sensor. The vehicle speed sensor detects the vehicle speed of the vehicle V. The handle angle sensor detects a rotation angle (handle angle) of the steering wheel to the left and right with reference to a state in which the steering wheel (front wheel tire in the present embodiment) faces in the front-rear direction of the vehicle V. The vehicle tilt sensor is, for example, a gyro sensor, and detects a tilt angle (hereinafter referred to as a lean angle) of the vehicle V based on a state where the vehicle V stands upright (see FIGS. 1 and 8). Signals indicating the vehicle speed, the handle angle, and the lean angle detected by the vehicle speed sensor, the handle angle sensor, and the vehicle tilt sensor are sent to the mirror array control unit 17.

The mirror array control unit 17 appropriately changes the inclination angles of the plurality of mirror cells 20 of the mirror array 10 based on the detection result of the state detection unit 18 described above.
The mirror array control unit 17 appropriately changes the tilt angles of the plurality of mirror cells 20 of the mirror array 10 based on, for example, the positions of the blinker switch and the light switch detected by the switch detection unit 18A. Further, the mirror array control unit 17 appropriately changes the tilt angles of the plurality of mirror cells 20 of the mirror array 10 based on, for example, the lean angle detected by the posture detection unit 18B.

  Further, the mirror array control unit 17 may obtain the cornering radius of the vehicle V based on the vehicle speed and the lean angle, for example. In this case, the mirror array control unit 17 predicts the traveling state (turning state) of the vehicle V based on the cornering radius, and appropriately changes the inclination angles of the plurality of mirror cells 20 of the mirror array 10 based on the prediction. The update of the steering wheel angle and lean angle data detected by the steering wheel angle sensor and the vehicle tilt sensor is faster than the update of the vehicle speed data detected by the vehicle speed sensor. For this reason, for example, the traveling state of the vehicle V may be predicted by detecting the displacement of the steering wheel angle and the lean angle at a predetermined vehicle speed and obtaining the above cornering radius.

  The mirror array controller 17 changes the tilt angle of the mirror cell 20 by selectively applying a driving potential to the plurality of electrodes 27 (see FIGS. 4 and 5) of each mirror cell 20. For example, the mirror array control unit 17 may have a function of holding a drive potential applied to the electrode 27, that is, a function of holding the mirror cell 20 at a predetermined inclination angle. The mirror array control unit 17 can control the plurality of mirror cells 20 independently.

Further, the blinker-equipped lighting device 1 of the present embodiment includes a light source control unit 30 that controls the operation of the light source unit 4. The light source control unit 30 controls the operation of the light source unit 4 based on the detection result of the switch detection unit 18A described above. For this reason, in the present embodiment, a signal indicating the position of the blinker switch or the light switch detected by the switch detection unit 18 </ b> A is also sent to the light source control unit 30.
The light source control unit 30 lights the light source unit 4 in a state where the blinker switch is arranged at a position where the blinker unit 3 blinks, and in a state where the lighting switch is arranged at a position where the lighting unit 2 lights up. In addition, the light source control unit 30 turns off the light source unit 4 in a state where the blinker switch is arranged at a position where the blinker unit 3 is turned off and the lighting switch is arranged at a position where the lighting unit 2 is turned off.
For example, the light source control unit 30 may change the light amount of the light source unit 4 based on the detection result of the state detection unit 18.

  Next, the operation when the blinker-equipped lighting device 1 configured as described above is provided in the vehicle V will be described. Here, operation | movement of the lighting apparatus 1 with a blinker accompanying the state change of the vehicle V is demonstrated. The change in the state of the vehicle V in the present embodiment includes a change in the state of the blinker switch and the light switch of the vehicle V and a change in the posture of the vehicle V.

[When the lighting section is lit and the vehicle does not tilt]
First, referring to FIGS. 8 and 9, the blinker-equipped lighting device 1 in the case where the lighting unit 2 is lit in accordance with the operation of the lighting switch and the vehicle V travels without being inclined in the vehicle width direction. The operation will be described.
As shown in FIG. 8, when the vehicle V travels in a state where the vehicle V does not tilt in the vehicle width direction (for example, the lean angle is 0 degree or a minute angle), specifically, on a straight road or a straight road. Consider a case where the vehicle travels on a curve with a large radius of curvature, or a vehicle turns at a sufficiently low speed even with a curve with a small radius of curvature. The traveling of the curve described above includes not only traveling on a curved road but also traveling when turning an intersection.

  When the vehicle V travels without tilting in the vehicle width direction, that is, when the lean angle obtained based on the signal from the attitude detection unit 18B is 0 degree or very small, the lighting unit of the blinker-equipped lighting device 1 2 light irradiates the area | region ahead of the vehicle V (the back side (front side) of the advancing direction D) of the road. This irradiation area is a first irradiation area LA1 in the center of the vehicle V in the vehicle width direction and a second irradiation area LA2 located on both sides in the vehicle width direction with respect to the first irradiation area LA1.

In this way, in order to emit light from the blinker-equipped lighting device 1, as shown in FIG. 9B, the light source unit 4 emits the light in the vertical first mirror cell group 10AH and the vertical second mirror cell group 10BH. All of the mirror array control unit 17 causes the light reflected by the mirror cell 20 (that is, all mirror cells 20 of the mirror array 10) to be configured to be projected onto the first reflection area 14A1 and the second reflection area 14A2 of the reflection mirror 14. The inclination angle of the mirror cell 20 is set.
In the present embodiment, the mirror array control unit is configured so that the light reflected by the horizontal first mirror cell group 10AW in the mirror array 10 is projected to the first reflection region 14A1 (first lighting unit 2A) of the reflecting mirror 14. 17 sets the inclination angle of the mirror cell 20 of the horizontal first mirror cell group 10AW. Thereby, the light reflected in the first reflection area 14A1 of the reflecting mirror 14 passes through the first passage area 15A of the lens cover 15 and irradiates the first irradiation area LA1 (see FIG. 8).

  On the other hand, the light reflected by the two horizontal second mirror cell groups 10BW is reflected on the second reflection regions 14A2 (each second lighting part 2B) on the side corresponding to the horizontal second mirror cell group 10BW in the reflecting mirror 14. The mirror array control unit 17 sets the inclination angle of the mirror cell 20 of the lateral second mirror cell group 10BW so as to be projected. For example, the mirror array control unit 17 projects the right second lateral direction so that the light reflected by the right lateral second mirror cell group 10BW is projected to the right second reflection region 14A2 (second lighting unit 2B). The inclination angle of the mirror cell group 10BW is set. Thereby, the light reflected in each second reflection area 14A2 of the reflecting mirror 14 passes through each second passage area 15B of the lens cover 15 and irradiates each second irradiation area LA2 (see FIG. 8).

  In this state, when the blinker switch is operated to blink the blinker unit 3, the mirror array control unit 17 causes the mirror cell 20 constituting the vertical second mirror cell group 10BH to have the light source as shown in FIG. The mirror cell 20 of the vertical second mirror cell group 10BH is set to the first tilt angle so that the light from the unit 4 is reflected and projected onto the third reflection region 14A3 of the reflecting mirror 14. Thereby, the light reflected in the third reflection region 14A3 of the reflecting mirror 14 passes through the third passage region 15C of the lens cover 15 (see FIG. 8), that is, the blinker portion 3 is turned on (temporarily turned on).

Further, as shown in FIG. 9B, the mirror array control unit 17 causes the mirror cell 20 constituting the vertical second mirror cell group 10 </ b> BH to reflect the light from the light source unit 4 and to perform the first reflection of the reflecting mirror 14. The mirror cells 20 of the vertical second mirror cell group 10BH are set to a second tilt angle different from the first tilt angle so as to project onto the region 14A1 and the second reflective region 14A2. Thereby, light does not reach the third reflection area 14A3 of the reflecting mirror 14 and the third passage area 15C of the lens cover 15, that is, the blinker portion 3 is turned off (temporarily turned off).
From the above, the mirror array control unit 17 causes the vertical second mirror cell group so that the mirror cells 20 of the vertical second mirror cell group 10BH swing between the first tilt angle and the second tilt angle. By controlling the operation of the 10BH mirror cell 20, the blinker unit 3 blinks.

In the blinking operation of the blinker unit 3 described above, when the blinker unit 3 is temporarily lit as shown in FIG. 9A, the mirror cells 20 constituting the vertical first mirror cell group 10 </ b> AH receive light from the light source unit 4. The mirror array control unit 17 sets the tilt angle of the mirror cell 20 of the vertical first mirror cell group 10AH so that it is reflected and projected onto the first reflection area 14A1 and the second reflection area 14A2 of the reflection mirror 14. Specifically, among the vertical first mirror cell group 10AH, the mirror cells 20 constituting the horizontal first mirror cell group 10AW reflect the light from the light source unit 4 and project it onto the entire first reflection region 14A1 of the reflecting mirror 14. . In addition, among the vertical first mirror cell group 10AH, the mirror cells 20 constituting each horizontal second mirror cell group 10BW reflect the light from the light source unit 4 and project it onto the entire second reflection region 14A2 of the reflecting mirror 14. . That is, even when the blinker unit 3 is temporarily turned on, the lighting state of the lighting unit 2 is ensured.
On the other hand, in the blinking operation of the blinker unit 3, when the blinker unit 3 is temporarily turned off as shown in FIG. 9B, all the mirror cells 20 of the mirror array 10 are the same as when the blinker unit 3 is not blinked. The mirror array control unit 17 sets the inclination angles of all the mirror cells 20 so that the light reflected at is projected onto the first reflection area 14A1 and the second reflection area 14A2 of the reflection mirror 14.

  Further, in the blinking operation of the blinker unit 3 described above, the light source control is performed in the state where the blinker unit 3 is temporarily turned on as shown in FIG. 9A compared with the state where the blinker unit 3 is temporarily turned off. The unit 30 increases the light amount of the light source unit 4. Thereby, the brightness of the lighting part 2 when the blinker part 3 is temporarily turned on (the brightness of the irradiation areas LA1 and LA2 irradiated by the light of the lighting part 2) is the same as that of the lighting part 2 when the blinker part 3 is temporarily turned off. It can be prevented from becoming darker than the brightness.

[When the lighting section is lit and the vehicle is tilted]
Next, referring to FIGS. 10 and 11, the vehicle V is in a state where the lighting unit 2 is turned on in response to the operation of the lighting switch and the vehicle V can travel a curve while maintaining a predetermined vehicle speed. The operation of the blinker-equipped lighting device 1 when traveling while tilting in the vehicle width direction will be described.

As shown in FIG. 10, when the vehicle V travels in an inclined state, that is, when the lean angle θ obtained based on the signal from the attitude detection unit 18B is equal to or larger than a predetermined angle, the mirror array control unit 17 If nothing is controlled, one second irradiation area LA2R located outside the curve is positioned on the far side in the traveling direction D of the vehicle V from the first irradiation area LA1. On the other hand, the direction in which the driver of the vehicle V wants to see positively when the vehicle V travels on the curve is the inside of the curve.
For this reason, when the vehicle V travels on a curve, one second irradiation area LA2R located outside the curve moves to a position adjacent to the other second irradiation area LA2L located inside the curve. In addition, the mirror array control unit 17 changes the tilt angle of the mirror cell 20 of one lateral second mirror cell group 10BW corresponding to one second irradiation region LA2R.

In order to emit light from the blinker-equipped lighting device 1 in this way, as shown in FIG. 11B, the light reflected by one lateral second mirror cell group 10 </ b> BW is reflected by the other side of the reflecting mirror 14. The tilt angle of the mirror cell 20 of one lateral second mirror cell group 10BW may be set so as to reflect in the second reflection region 14A2 corresponding to the second mirror cell group 10BW and its vicinity. The inclination angle of the mirror cell 20 of the other second horizontal mirror cell group 10BW may be set in the same manner as when the vehicle V travels without being inclined in the vehicle width direction.
Then, the light reflected in the left and right second reflecting areas 14A2 and the vicinity thereof in the reflecting mirror 14 passes through the left and right second passing areas 15B in the lens cover 15, as shown in FIG. The second irradiation area LA2 is irradiated. Thereby, two 2nd irradiation area | regions LA2 can be distribute | arranged inside the curve with respect to 1st irradiation area | region LA1.

In this state, the operation of the mirror cell 20 when the blinker switch is operated to blink the blinker unit 3 is the same as the case where the vehicle V does not tilt.
That is, in the mirror array control unit 17, as shown in FIG. 11A, the mirror cell 20 constituting the vertical second mirror cell group 10BH reflects the light from the light source unit 4 and the third reflection of the reflection mirror 14. The mirror cell 20 of the vertical second mirror cell group 10BH is set to the first tilt angle so as to project onto the region 14A3. Thereby, the blinker part 3 lights up temporarily.
In addition, as shown in FIG. 11B, the mirror array control unit 17 reflects the light from the light source unit 4 so that the mirror cell 20 constituting the vertical second mirror cell group 10BH reflects the first reflection of the reflecting mirror 14. The mirror cell 20 of the vertical second mirror cell group 10BH is set to the second tilt angle so as to project onto the region 14A1 and the second reflection region 14A2. Thereby, the blinker part 3 is temporarily turned off.

[When the lighting is off]
Next, with reference to FIG. 12, operation | movement of the lighting apparatus 1 with a blinker in the state which the lighting part 2 turned off according to operation of a lighting switch is demonstrated. The description here does not matter whether or not the vehicle V is traveling.
When the blinker unit 3 is blinked by operating the blinker switch in the state in which the lighting unit 2 is turned off, the mirror array control unit 17 causes all the mirror cells 20 of the mirror array 10 to have the light source unit 4 as shown in FIG. The tilt angles of all the mirror cells 20 are set so that the light from the reflected light is reflected and projected onto the third reflecting region 14A3 of the reflecting mirror 14. Then, the light source control unit 30 causes the light source unit 4 to blink, whereby the blinker unit 3 blinks.

  As described above, according to the blinker-equipped lighting device 1 of the present embodiment, the mirror cells 20 constituting all of the vertical second mirror cell groups 10BH in the mirror array 10 or all the mirror cells in accordance with the operation of the blinker switch. The light distribution between the light projected from the light source unit 4 to the lighting unit 2 and the light projected from the light source unit 4 to the blinker unit 3 is switched by changing the inclination angle of 20. For this reason, it is possible to turn on the lighting unit 2 and blink the blinker unit 3 using the same light source unit 4. Thereby, size reduction of the lighting apparatus 1 with a blinker can be achieved easily.

  Further, according to the lighting device with blinker 1 of the present embodiment, when the lighting unit 2 is turned on according to the operation of the lighting switch, the mirror cell 20 of the vertical second mirror cell group 10BH has the first tilt angle and the first tilt angle. By swinging between two tilt angles, the blinker unit 3 can be blinked. That is, the blinker unit 3 can be turned on and off temporarily. Further, in the state where the blinker unit 3 is temporarily turned off during the blinking operation of the blinker unit 3, the light reflected by the mirror cells 20 of the vertical second mirror cell group 10 </ b> BH is also projected onto the lamp unit 2. Light can be used effectively.

  Further, according to the lighting device with blinker 1 of the present embodiment, since the blinker unit 3 includes the color filter 16, the light projected on the blinker unit 3 is colored light (orange light) colored in the color filter 16. Can do. On the other hand, since the light projected to the lighting unit 2 does not pass through the color filter 16, the light of the lighting unit 2 is the same color light (for example, white light) as the light source unit 4, and the light color of the blinker unit 3 Different. Since the color of the light is different between the lighting part 2 and the winker part 3, the light of the lighting part 2 and the light of the winker part 3 can be easily distinguished. In particular, in the present embodiment, in the lens cover 15, the first and second passage areas 15 </ b> B that form the lighting part 2 and the third passage area 15 </ b> C that forms the winker part 3 are adjacent to each other. It is effective to make the color of light different from the part 3.

  Further, according to the lighting device with blinker 1 of the present embodiment, since the color filter 16 is provided in the third reflection region 14A3 (a part of the reflection mirror 14) of the reflection mirror 14, the third passage of the lens cover 15 is performed. The size of the color filter 16 can be set smaller than that provided in the region 15C.

In the lighting device with blinker 1 of the first embodiment, for example, only the first lighting part 2A of the lighting part 2 is lit, and the second lighting part 2B may not be lit. That is, the sub headlight does not always have to function.
When only the first lighting unit 2A is lit, for example, as shown in FIG. 13B, the light emitted from the light source unit 4 and reflected by all the mirror cells 20 constituting the mirror array 10 is reflected by the reflecting mirror 14. The mirror array control unit 17 may set the inclination angles of all the mirror cells 20 so as to be projected onto the first reflection region 14A1. Thereby, compared with the case where the light emitted from the light source unit 4 is projected onto both the first reflection region 14A1 and the second reflection region 14A2 of the reflecting mirror 14, the light amount of the light source unit 4 is reduced, that is, Even if the power consumption is reduced, the brightness of the first lighting part 2A can be ensured.

  Further, in the state where only the first lighting part 2A is lit as described above, when the blinker part 3 is blinked by operating the blinker switch, as in the case of the first embodiment, for example, The first tilt angle at which the mirror cell 20 constituting the two mirror cell group 10BH reflects the light from the light source unit 4 and projects it onto the third reflection region 14A3 of the reflecting mirror 14, and reflects and reflects the light from the light source unit 4. You may rock | fluctuate between 2nd inclination angles projected on 14 A1 1st reflective area | region of the mirror 14. FIG.

When only the first lighting part 2A is lit as described above, when the blinker switch is operated to blink the blinker part 3, for example, as shown in FIG. 13, the first horizontal mirror cell group Two horizontal second mirror cell groups 10BW on both the left and right sides of 10AW are made to correspond to the blinker portions 3 on both left and right sides, respectively, and the left and right lateral mirror cell groups 10BW are used for blinking of the left and right blinker portions 3 respectively. Also good.
More specifically, when blinking one of the left and right winker units 3 as shown in FIG. 13, the mirror cells 20 constituting one lateral second mirror cell group 10 </ b> BW corresponding to the one winker unit 3. As shown in FIG. 13 (a), a first inclination angle that reflects light from the light source unit 4 and projects it onto one third reflection region 14A3 that forms one winker unit 3 of the reflecting mirror 14, and As shown in FIG. 13B, the light may be swung between a second inclination angle at which light from the light source unit 4 is reflected and projected onto the first reflection region 14A1 of the reflecting mirror 14.

Further, in the lighting device with blinker 1 of the first embodiment, for example, as shown in FIG. 14, at least a part of the mirror cells 20 out of the plurality of mirror cells 20 is emitted from the light source unit 4 according to the operation of the blinker switch. The light may be the spot light SL projected on a part of the winker unit 3 and may be swung so that the spot light SL moves in the winker unit 3.
Specifically, the spot light SL is light reflected by a plurality of mirror cells 20 and projected onto a part of the third reflection area 14A3 of the reflecting mirror 14 and a part of the third passage area 15C of the lens cover 15. is there.

The spot light SL moves in the winker unit 3 (in the third reflection region 14A3 of the reflecting mirror 14 in FIG. 14) by the plurality of mirror cells 20 that make up the spot light swinging in cooperation. The spot light SL moves in the winker unit 3 at such a speed that an afterimage effect can be obtained. Thereby, the light reflected in the several mirror cell 20 can be projected on the whole blinker part 3 (3rd reflective area | region 14 A3).
The creation and movement of the spot light SL is performed only when the blinker unit 3 is temporarily turned on. For this reason, for example, when the blinker unit 3 is blinked while the lighting unit 2 is lit, the mirror cell 20 used for the blinker unit 3 is an afterimage with reference to the first tilt angle of the mirror cell 20 corresponding to when the blinker unit 3 is temporarily lit. The rocking may be performed at such a speed as to obtain an effect.

For example, a single spot light SL may be created by all the mirror cells 20 used in the winker unit 3, but a plurality of spot lights SL are created in the example shown in FIG. Hereinafter, the spot light SL will be described more specifically.
A part (five in FIG. 14) of mirror cells 20 used in the winker unit 3 is one cell unit 10U, and one spot light SL is produced by one cell unit 10U. The plurality of mirror cells 20 constituting the same cell unit 10U may be arranged in the left-right direction as shown in FIG. 14, but may be arbitrarily arranged.
The spot light projection area SLA of each spot light SL projected toward the winker section 3 moves in a partial area (spot light movement area SMA) of the winker section 3.

The spot light movement area SMA has a strip shape, and the spot light projection area SLA moves in the longitudinal direction of the spot light movement area SMA. For this reason, the dimension in the short direction of the spot light moving area SMA is equivalent to the dimension of the spot light projection area SLA corresponding thereto.
In FIG. 14, the dimension in the longitudinal direction of the spot light moving area SMA is set to five times the dimension of the spot light projection area SLA corresponding thereto, but is not limited thereto. Further, the strip-shaped spot light movement area SMA may be formed in a straight line without being folded as shown in FIG. 14, for example, or may be formed so as to be folded in the middle. Further, the longitudinal direction of the spot light moving area SMA may extend in the left-right direction as shown in FIG. 14, for example, but is not limited thereto.

The plurality of spot light movement regions SMA are not limited to be arranged vertically and horizontally as illustrated in FIG. 14, but may be arranged to be adjacent to each other at least.
The operation of the mirror cell 20 for creating or moving the spot light SL can be controlled by the mirror array control unit 17 (see FIG. 7).

  In the case of adopting the above configuration, the blinker unit 3 can be illuminated brightly by moving the spot light SL at a speed at which the afterimage effect can be obtained in the blinker unit 3. For this reason, even if the number of mirror cells 20 used for the winker unit 3 is small, the brightness of the winker unit 3 can be ensured. Moreover, it becomes possible to use more mirror cells 20 for the lighting part 2, and the brightness of the lighting part 2 can be ensured easily. Therefore, the brightness of the blinker unit 3 and the lighting unit 2 can be ensured without increasing the light amount of the light source unit 4, that is, without increasing the power consumption.

  The above-described spot light SL and a method for moving the spot light SL may be applied to, for example, light projected on the lighting unit 2. In this case, the light quantity of the light source unit 4 is increased even when the number of mirror cells 20 used for the lighting unit 2 when the winker unit 3 is temporarily turned on is smaller than the number when the winker unit 3 is temporarily turned off. And the brightness of the lighting part 2 can be ensured.

When the light projected onto the winker unit 3 is the spot light SL as described above, for example, as shown in FIG. 15, the spot light moving region SMA (spot light moving region) in the winker unit 3 has a predetermined shape. May be made.
Each of the shapes illustrated in FIGS. 15A and 15B is created using a plurality of spot light moving areas SMA. The shape illustrated in FIG. 15A is a quadrangular shape, and can be obtained by arranging a plurality of linearly extending spot light moving regions SMA adjacent to each other in the width direction (vertical direction in FIG. 15A). It is done. The shape illustrated in FIG. 15B is a triangular shape having one of the left and right sides (the right side in FIG. 15B) as a vertex, and is vertically above and below the first spot light moving region SMA1 extending in a straight line. It can be obtained by arranging, on both sides, a belt-like second spot light movement region SMA2 that is folded back halfway.

The relative movement direction of the spot light projection area SLA in the plurality of spot light movement areas SMA may be set so as to look like a predetermined shape by the afterimage effect. Specifically, the two spot light projection areas SLA may be set so as not to move in the same direction while being adjacent to each other.
For example, when a plurality of spot light movement areas SMA are arranged as shown in FIG. 15A, the movement directions of the spot light projection areas SLA are opposite to each other between two adjacent spot light movement areas SMA. It should be set.

  For example, when a plurality of spot light movement areas SMA are arranged as shown in FIG. 15B, the movement start positions of the spot light projection areas SLA are the first spot light movement area SMA1 and the second spot light movement area. It may be located away from the SMA 2. Furthermore, the movement direction of the spot light projection area SLA moving in the area adjacent to the first spot light movement area SMA1 in the second spot light movement area SMA2 is the movement of the spot light projection area SLA in the first spot light movement area SMA1. It is good to set it in the opposite direction.

When the spot light movement area SMA in the blinker portion 3 has a predetermined shape, the direction in which the vehicle V is bent can be clearly shown. In particular, when the predetermined shape is a triangular shape having one of the left and right as the apexes, the direction in which the vehicle V bends is indicated by an arrow, so that the direction in which the vehicle V bends can be shown more clearly.
The predetermined shape is not limited to a triangular shape or a quadrangular shape, and may be an arbitrary shape such as a circular shape. The predetermined shape may be a shape representing, for example, letters, numbers, or symbols.

  Further, the predetermined shape of the winker unit 3 formed by the spot light moving area SMA may change every time the winker unit 3 blinks, as shown in FIG. In this case, the direction in which the vehicle V bends can be shown more clearly.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS.
The second embodiment differs from the first embodiment only in the configuration of the blinker part, and the other configurations are the same. Moreover, the same code | symbol is attached | subjected to the same structure as 1st embodiment, and detailed description is abbreviate | omitted.

As shown in FIG. 17, the blinker portion 3N of the lighting device with blinker according to the present embodiment blinks by the operation of the blinker switch provided in the vehicle V, similarly to the first embodiment. The third reflection area 14A3 and the third passage area 15C of the lens cover 15 (see FIG. 1).
In addition, as shown in FIGS. 17 and 18, the winker unit 3 </ b> N according to the present embodiment includes a diffusing unit 50 provided corresponding to a region where the light L from the light source unit 4 is projected. The diffusing unit 50 diffuses the light L projected on the winker unit 3N. The diffusion unit 50 may be, for example, a Fresnel lens or a prism, but the diffusion unit 50 of the present embodiment is a convex lens.

The diffusing unit 50 may be provided at least in the optical path from the mirror array 10 to the lens cover 15. For example, the diffusion unit 50 may be provided in the third passage region 15C of the lens cover 15, but in the present embodiment, the diffusion unit 50 is provided in the third reflection region 14A3 of the reflecting mirror 14.
In addition, a plurality of diffusion units 50 according to the present embodiment are arranged at intervals. In the present embodiment, the plurality of diffusing portions 50 include a first diffusing portion 50A located at the center of the third reflecting region 14A3 of the reflecting mirror 14 and a vertical direction at each end in the left-right direction of the third reflecting region 14A3. And two second diffusion parts 50B arranged at intervals. Each second diffusion portion 50B is positioned so as to be shifted upward or downward with respect to the first diffusion portion 50A.

Furthermore, the winker unit 3N of the present embodiment may include a color filter 16N similar to that of the first embodiment. The color filter 16N may be disposed so as to transmit the light L diffused by the diffusion unit 50, for example, or may be disposed such that the color light transmitted through the color filter 16N is diffused by the diffusion unit 50, for example.
In this embodiment, as illustrated in FIG. 8, the color filter 16 </ b> N and the diffusing unit 50 are arranged in order on the reflecting surface 14 </ b> A of the reflecting mirror 14. For this reason, the light L projected onto the winker unit 3N passes through the color filter 16N to become colored light, and is then diffused by the diffusion unit 50.
For example, the color filter 16N may be provided in the entire third reflection region 14A3 of the reflecting mirror 14, but in the present embodiment, the color filter 16N is provided only in a portion of the third reflection region 14A3 that overlaps the diffusion unit 50.

The operation when the blinker-equipped lighting device of the present embodiment is provided in the vehicle V is the same as that of the first embodiment.
However, in the present embodiment, when blinking the blinker unit 3N, specifically, when temporarily turning on the blinker unit 3N, the light L projected on the blinker unit 3N is projected only on the diffusion unit 50. The mirror array control unit 17 may appropriately set the inclination angle of the mirror cells 20 constituting the vertical second mirror cell group 10BH and the horizontal second mirror cell group 10BW.

In order to project the light L projected on the winker unit 3N only on the diffusing unit 50, for example, the light L projected on the winker unit 3N is used as the spot light SL (see FIG. 14), and this spot light SL is used as the diffusing unit. What is necessary is just to project to 50.
In the present embodiment, since the winker unit 3N includes the plurality of diffusion units 50, when the winker unit 3N is temporarily turned on, for example, a plurality of spot lights SL are transmitted to all the diffusion units 50 or selected diffusion units. 50 may be respectively projected.

Since the light L projected on the diffusion unit 50 is diffused by the diffusion unit 50, the optical path section PS of the light L after passing through the diffusion unit 50 is separated from the diffusion unit 50 as shown in FIG. Therefore, it becomes large. In the present embodiment, since the light L that has passed through the diffusing unit 50 is projected onto the third passage region 15C of the lens cover 15, the optical path cross section PS increases as it approaches the third passage region 15C of the lens cover 15. In FIG. 19, the optical path cross section PS of the light L in the third passage region 15C of the lens cover 15 is shown.
Further, when the spot lights SL are respectively projected onto the mutually adjacent diffusing portions 50, a part of the adjacent optical path sections PS can be overlapped with each other in the third passage region 15 </ b> C of the lens cover 15.

As described above, the blinker-equipped lighting device of the present embodiment has the same effects as those of the first embodiment.
Moreover, according to the lighting device with a blinker of the present embodiment, the light L projected on the blinker unit 3N is diffused by the diffusion unit 50. For this reason, even if the area | region where the light L is projected in the blinker part 3N is small, the blinking area | region of the blinker part 3N visible from the outer side of the vehicle V can be enlarged. Therefore, the blinker portion 3N can be configured in a compact manner, and the lighting device with blinker can be downsized. In particular, in the present embodiment, since the third reflecting region 14A3 constituting the winker portion 3N of the reflecting mirror 14 can be set small, the lighting device with a winker can be downsized.

  In addition, according to the lighting device with turn signal according to the present embodiment, the color filter 16N and the diffusion unit 50 forming the turn signal portion 3N are distributed and arranged in the third reflection region 14A3. For this reason, for example, when the light L from the light source unit 4 is projected on the entire third reflection region 14A3, the light L reflected on the third reflection region 14A3 is substantially uncolored light (for example, white light), The lens cover 15 can pass through the third passage region 15C. Therefore, the third reflection area 14A3 of the reflecting mirror 14 and the third passage area 15C of the lens cover 15 may be used for both the winker part 3N and the lighting part 2 (the first lighting part 2A and the second lighting part 2B). it can.

  Moreover, according to the lighting device with a blinker of the present embodiment, when the spot light SL is projected onto the plurality of diffusion units 50, the plurality of optical path sections PS enlarged by the diffusion unit 50 can be superimposed on each other.
