  Hereinafter, an example in which a lighting device according to an embodiment of the present invention is mounted on an automobile will be described with reference to the accompanying drawings.

(Embodiment 1)
In FIG. 1, in an automobile 1, lighting devices 3 called headlights are arranged on both front sides of a main body 2.

As shown in FIGS. 2 and 3, the lighting device 3 includes a main body case 5 having an opening 4 on the front side, a translucent cover 6 that covers the opening 4 of the main body case 5, and the main body case 5. A lens 7 disposed in a portion facing the cover 6 inside, a digital mirror device 8 disposed on the light incident surface side of the lens 7, and supplying light toward the digital mirror device 8 And a control unit 10 connected to the illuminator 9 and the digital mirror device 8, an infrared camera 11 connected to the control unit 10, a memory 14, and an operating unit 15.

  As shown in FIGS. 4 and 5, the illuminator 9 is disposed between the blue laser element 12 used as an example of a light emitting element, the blue laser element 12 and the digital mirror device 8, and the blue laser From the light of the element 12, red light (R), green light (G), blue light (B), and infrared light (IR) are generated, and these red light (R), green light (G), and blue light are generated. (B), a rotating wheel 13 (an example of a color conversion element) that supplies infrared light (IR) toward the digital mirror device 8 is used.

  The rotating wheel 13 generates red light (R), green light (G), blue light (B), and infrared light (IR) from the blue light supplied from the blue laser element 12. It is divided into four areas every 90 degrees, and each area is divided into red light (R), green light (G), blue light (B), and infrared light (from the blue light supplied from the blue laser element 12). IR) and the like are provided.

  In addition, the fluorescent substance etc. which produce red light (R), green light (G), blue light (B), and infrared light (IR) from the blue light supplied from the blue laser element 12 are already known. Therefore, when the blue light is irradiated and passes through the rotating wheel 13, red light (R), green light (G), blue light (B), Infrared light (IR) is created.

  The light receiving portion of the infrared camera 11 is disposed outside the light irradiation range 16 of the lens 7 as shown in FIG.

  The feature of this embodiment is that it is possible to detect a driving attention object such as the oncoming vehicle 17 shown in FIG. 7 or the pedestrian 18 shown in FIG. 8 and the type of these driving attention objects. That is, it is possible to change the lighting state.

  Hereinafter, detailed description will be made focusing on this point.

  First, when the headlight 3 is turned on with the operation device 15 (S1 in FIG. 6), the control unit 10 drives the rotary wheel 13 to rotate (S2 in FIG. 6), and then the digital mirror device (DMD). 8 is activated (S3 in FIG. 6).

  Subsequently, the control unit 10 activates the blue laser element 12 and the infrared camera 11 serving as a light source, and the light irradiation range 16 shown in FIG. 2 is irradiated with light, and the illumination of FIGS. 7 and 8 is performed (FIG. 6). S4).

  Specifically, when the blue light supplied from the blue laser element 12 is irradiated onto the rotating wheel 13, the rotating wheel 13 rotates at a high speed, and thus the upper right of FIG. As shown, red light (R), green light (G), blue light (B), and infrared light (IR) are continuously generated, and these lights are reflected as a surface by the digital mirror device 8. Then, it irradiates toward the light irradiation range 16 through the lens 7.

As can be understood from the description on the upper right side of FIG. 4, the red light (R) is reflected as a surface by the digital mirror device 8, and then toward the light irradiation range 16 through the lens 7. Irradiated. Next, the green light (G) is reflected as a surface by the digital mirror device 8 and then irradiated toward the light irradiation range 16 through the lens 7, and then the blue light (B) is applied to the digital mirror. Reflected as a surface at the device 8 and then illuminated through the lens 7 towards the light illumination range 16, then infrared light (IR) is reflected as a surface at the digital mirror device 8, and then The light is irradiated toward the light irradiation range 16 through the lens 7.

  At this time, since the rotating wheel 13 is rotating at a high speed, the red light (R), the green light (G), and the blue light (B) are continuously changed at a high speed. For the person 18, white light is irradiated toward the light irradiation range 16, and the person 18 feels that the light is illuminated with white light.

  In addition, infrared light (IR) is irradiated at high speed intermittently toward the light irradiation range 16 through the lens 7, but this infrared light (IR) is applied to humans. It is invisible and does not affect the illumination of white light.

  However, since this infrared light (IR) is also irradiated at high speed intermittently toward the light irradiation range 16 via the lens 7, the driving attention target in the light irradiation range 16 is substantially always provided. The presence of an object can be detected (S5 in FIG. 6).

  That is, the infrared camera 11 captures a reflected image from the driving caution object, and then compares the image with the type of the driving caution object stored in the memory 14 of FIG. 10 can determine that the driving caution object is the oncoming vehicle 17 shown in FIG. 7 or the pedestrian 18 shown in FIG.

  Moreover, this control part 10 can also reduce light or change a color according to the kind of driving attention object.

  Specifically, when the driving attention object is the oncoming vehicle 17 shown in FIG. 7, the area near the oncoming vehicle 17 needs to be in a non-illuminated state (S6 in FIG. 6), and so on. In order to achieve this, the mirror part of the digital mirror device 8 is driven so that the reflected light from the digital mirror device 8 is not irradiated to the part (S7 in FIG. 6).

  In addition, the area near the oncoming vehicle 17 can be in a dimmed state.

  Specifically, for the portion corresponding to the area near the oncoming vehicle 17 of the digital mirror device 8, the area near the oncoming vehicle 17 is dimmed by shortening (thinning out) the time for reflecting light. It can also be a state.

  Also, as shown in FIG. 8, when the driving caution object is a pedestrian 18, similarly, particularly the face portion needs to be in a non-illuminated state or dimmed state (S <b> 6 in FIG. 6). In order to do so, the mirror part of the digital mirror device 8 is driven so that the part is not irradiated with light, or the time for reflecting the light is shortened (thinning out state). (S7 in FIG. 6).

  Note that the face portion of the pedestrian 18 can be easily determined by using an image recognition technique performed by a camera or the like.

  In order to make it easy for the driver to understand the presence of the pedestrian 18, for example, when yellow light is irradiated to the area below the pedestrian 18 's face, there is a place to be toned. (S8 in FIG. 8).

In this case, the mirror part of the digital mirror device 8 is driven to irradiate red light (R) and green light (G) by reflection on the area part below the face of the pedestrian 18, If the blue light (B) is non-reflecting and non-irradiating, the area below the face of the pedestrian 18 is irradiated with yellow light (S9 in FIG. 6).

  If it is determined in (S6 in FIG. 6) that there is no place for light shielding or dimming, it is next determined whether or not there is a place to be toned (S8 in FIG. 6).

In this case, for example, in (S7 of FIG. 6), when it is determined that there is a bicycle to move forward as a driving caution object, the mirror portion of the digital mirror device 8 is also driven at this time. If the bicycle area is irradiated with red light (R) and green light (G) by reflection, the blue light (B) is non-reflective and non-irradiated, the bicycle area will receive yellow light. Irradiated state (S9 in FIG. 6)
If it is determined in (S8 in FIG. 6) that there is no area to be toned, the mirror portion of the digital mirror device 8 is not driven and the entire surface is reflected (see FIG. 6). S10).

  Further, when the headlight 3 is turned off with the operation device 15, the control unit 10 turns off the blue laser element 12, the infrared camera 11, the rotating wheel 13, and the digital mirror device 8 (S11 in FIG. 6). ).

  Moreover, although it is a modification of this embodiment, the blue laser element 12, the infrared camera 11, the rotating wheel 13, and the digital mirror are controlled by the control unit 10 even when the operation unit 15 is turning off the headlight 3. It is also possible to drive the device 8 and perform only the driving attention object detection by infrared light (IR).

  For example, there is no need for illumination in the daytime, and in this case, if the blue laser element 12 is driven only at the infrared light (IR) generation point of the rotating wheel 13, the lower right of FIG. As described above, only the infrared light (IR) is irradiated toward the light irradiation range 16 by the digital mirror device 8, and the driving attention object can be detected.

(Embodiment 2)
FIG. 9 shows another embodiment of the present invention.

  In this embodiment, the illuminator 9 of the above (Embodiment 1) is configured by a blue laser element 12 and an infrared light emitting element 19 (IR light emitting element).

  That is, infrared light (IR) is generated by the infrared light emitting element 19, reflected by the mirrors 20 and 21, and supplied to the rotating wheel 13 side.

  The rotating wheel 13 generates red light (R), green light (G), and blue light (B) from the blue light supplied from the blue laser element 12. Divided into areas, each of the three areas is provided with a fluorescent material or the like that generates red light (R), green light (G), and blue light (B) from the blue light supplied from the blue laser element 12. Yes.

  The remaining one area was transparent so that infrared light (IR) could pass through. That is, in this embodiment, as shown in the upper right of FIG. 9, the rotating wheel 13 rotates to form red light (R), green light (G), and blue light (B) from the blue light of the blue laser element 12. When it is turned on, it is turned on, but when it is irradiated with infrared light (IR), it is turned off.

On the other hand, the infrared light emitting element 19 rotates the rotating wheel 13 to form red light (R), green light (G), and blue light (B) from the blue light of the blue laser element 12. However, it is in the OFF state, but it is in the ON state when irradiated with infrared light (IR).

  Further, when there is no need for illumination in the daytime, as shown in the lower right of FIG. 9, the blue laser element 12 is turned OFF, and the infrared light emitting element 19 rotates the rotating wheel 13, and the blue light of the blue laser element 12 is rotated. Therefore, when red light (R), green light (G), and blue light (B) are formed, the light is turned off, but when infrared light (IR) is irradiated, the light is turned on.

  The mirror 21 can pass blue light from the blue laser element 12.

  Further, the basic operation described with reference to FIGS. 6 to 8 is the same as the above (Embodiment 1).

(Embodiment 3)
10 to 13 show another embodiment of the present invention.

In this embodiment, the infrared camera 11 used in (Embodiment 1) is replaced with TOF (Time
The distance image camera 22 of the “Off Flight” method was used.

  As already known, the distance image camera 22 can determine the distance from the video to the driving caution object, and according to this, the driving caution object from the main body 2 of the automobile 1 can be determined. Since the distance to the object can be measured, an alarm can be issued from the alarm device 23 in FIG.

  In other words, in this embodiment, for example, as shown in FIG. 13, when the presence and distance of the pedestrian 18 in the blind spot is detected from the driver and it is determined that it is dangerous, the alarm 23 It is set as the structure which issues a warning from.

  In order to perform such an operation, the distance image camera 22 and the alarm device 23 are connected to the control unit 10 together with the digital mirror device 8, the blue laser element 12, the rotating wheel 13, and the memory 14. Yes.

  In this embodiment, first, when the engine 15 (not shown) of the automobile 1 is activated by the operating device 15 (S1 of FIG. 12), the control unit 10 first activates the blue laser element 12 and the distance image camera 22, The rotary wheel 13 is driven to rotate (S2 in FIG. 12), and then the digital mirror device 8 is activated (S3 in FIG. 12).

  Next, the control unit 10 determines whether or not the headlight 3 is turned on by the operation device 15 (S4 in FIG. 12).

  When it is determined that the headlight 3 is turned on, the blue laser element 12 is turned on in the entire area of the rotating wheel 13.

  Then, the blue light supplied from the blue laser element 12 is applied to the rotating wheel 13 and the rotating wheel 13 is rotated at a high speed, so that red light (R), green, as shown in the upper right of FIG. Light (G), blue light (B), and infrared light (IR) are continuously generated, and these lights are reflected as a surface by the digital mirror device 8, and then the light irradiation range through the lens 7. 16 is irradiated.

  As can be understood from the description on the upper right side of FIG. 10, the red light (R) is reflected as a surface by the digital mirror device 8, and then toward the light irradiation range 16 through the lens 7. Irradiated. Next, the green light (G) is reflected as a surface by the digital mirror device 8 and then irradiated toward the light irradiation range 16 through the lens 7, and then the blue light (B) is applied to the digital mirror. A state where the light is reflected as a surface by the device 8 and then irradiated toward the light irradiation range 16 via the lens 7, and then infrared light (IR) is reflected as a surface by the digital mirror device 8; Thereafter, the light is irradiated toward the light irradiation range 16 through the lens 7.

  At this time, since the rotating wheel 13 is rotating at a high speed, the red light (R), the green light (G), and the blue light (B) are continuously changed at a high speed. For the person 18, white light is irradiated toward the light irradiation range 16 and can be felt as being illuminated with white light.

  In addition, infrared light (IR) is irradiated at high speed intermittently toward the light irradiation range 16 through the lens 7, but this infrared light (IR) is applied to humans. It is invisible and does not affect the illumination of white light.

  However, since this infrared light (IR) is also irradiated at high speed intermittently toward the light irradiation range 16 via the lens 7, the driving attention target in the light irradiation range 16 is substantially always provided. The presence of an object can be detected (S6 in FIG. 12).

  In other words, the distance image camera 22 captures a reflection image from the driving attention object, and then the image is compared with the type of the driving attention object stored in the memory 14 of FIG. The unit 10 can detect that the driving attention object is the oncoming vehicle 17 illustrated in FIG. 7 or the pedestrian 18 illustrated in FIG. 8 and the distance to those driving attention objects.

  Moreover, this control part 10 can also carry out light reduction and a color change according to the kind of driving attention target object similarly to the said (Embodiment 1).

  Specifically, when the driving caution target is the oncoming vehicle 17 shown in FIG. 7, the area near the oncoming vehicle 17 needs to be in a non-illuminated state. The mirror portion of the digital mirror device 8 is driven so that the reflected light from the digital mirror device 8 is not irradiated on the portion.

  In addition, the area near the oncoming vehicle 17 can be in a dimmed state.

  Specifically, for the portion corresponding to the area near the oncoming vehicle 17 of the digital mirror device 8, the area near the oncoming vehicle 17 is dimmed by shortening (thinning out) the time for reflecting light. It can also be a state.

  Also, as shown in FIG. 8, when the driving attention object is a pedestrian 18, similarly, especially the face portion needs to be in a non-illuminated state or a dimmed state. First, the mirror part of the digital mirror device 8 is driven so that light is not irradiated on the part, or the time for reflecting the light is shortened (thinned out).

  Note that the face portion of the pedestrian 18 can be easily determined by using an image recognition technique performed by a camera or the like.

  In order to make it easy for the driver to understand the presence of the pedestrian 18, for example, when yellow light is irradiated to the area below the pedestrian 18 's face, there is a place to be toned. .

  In this case, the mirror part of the digital mirror device 8 is driven to irradiate red light (R) and green light (G) by reflection on the area part below the face of the pedestrian 18, If the blue light (B) is in a non-reflective and non-irradiated state, the area below the face of the pedestrian 18 is irradiated with yellow light.

  If there is no place for light shielding or dimming, it is next determined whether or not there is a place to be toned.

  In this case, for example, when it is determined that there is a bicycle to move forward as a driving caution object, the mirror portion of the digital mirror device 8 is also driven at this time to the bicycle area portion, If the red light (R) and the green light (G) are irradiated by reflection, and the blue light (B) is non-reflected and non-irradiated, the bicycle area is in a state of being irradiated with yellow light.

  If it is determined that there is no area to be toned, the mirror portion of the digital mirror device 8 is not driven, and the entire surface is reflected.

  In the present embodiment, in (S6 in FIG. 12), the distance image camera 22 captures a reflected image from the driving caution target (obstacle), and then stores the image in the memory 14 in FIG. As a result, the control unit 10 determines that the driving attention object is the oncoming vehicle 17 shown in FIG. 7 or the pedestrian 18 shown in FIG. The distance to those driving attention objects can be detected.

  In (S6 in FIG. 12), since the type and distance of the driving caution target can also be detected, if it is determined that the vehicle is in a dangerous state, an alarm can be issued from the alarm device 23 (S7 in FIG. 12).

  If it is determined that the vehicle is not in a dangerous state based on the type and distance of the driving attention object detected in (S6 in FIG. 12), the alarm from the alarm device 23 is not issued (S8 in FIG. 12).

  On the other hand, when the headlight 3 is not turned on by the operating device 15, the blue laser element 12 is driven only when the infrared light (IR) generation point of the rotating wheel 13 is generated as shown in the lower right of FIG. (S9 in FIG. 12).

  Then, as shown in the lower right of FIG. 10, only the infrared light (IR) can be emitted toward the light irradiation range 16 by the digital mirror device 8 to detect the driving attention object.

  That is, it is possible to detect a driving attention object even in the daytime.

(Embodiment 4)
