Abstract

<P>PROBLEM TO BE SOLVED: To provide a lighting fixture for viewing night vision around a vehicle which cannot view reddish light from the outside and prevents the output of infrared ray from lowering. <P>SOLUTION: An infrared LED 32 and a white LED 35 are installed in the lighting fixture 30 radiating infrared ray in a specified direction. The infrared LED 32 radiates infrared ray and slight reddish light in lighting, and the white LED 35 radiates visible light in lighting. When lighting the lighting fixture 30 for viewing nigh vision around the vehicle, the infrared LED 32 and the white LED 35 are both lit. Since the radiated light of the infrared LED 32 is mixed with the radiated light of the white LED 35, the reddish light from the infrared LED 32 is confused with visible light from the white LED 35 and cannot be viewed from the outside. Also, since the infrared ray light cannot be viewed from the outside, the output of the infrared LED 32 must not be lowered since the reddish light cannot be viewed from the outside. As a result, the viewing of the infrared ray from the outside can be prevented without lowering the output of the infrared ray. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a vehicle peripheral night vision lamp and a vehicle outside mirror device. In particular, the present invention relates to a vehicle peripheral night vision lamp that can reduce the visibility of red light from the outside even when the vehicle peripheral night vision lamp is turned on. The present invention also relates to a vehicle outside mirror device provided with both a vehicle periphery imaging device and the vehicle periphery night vision lamp.

  A conventional vehicle peripheral night vision lamp is provided together with a vehicle peripheral imaging device that images a blind spot portion from a driver's seat around the vehicle. This vehicle periphery imaging device is provided with a CCD camera or the like for imaging the periphery of the vehicle, and the driver outputs an image captured by the CCD camera to an output screen provided in the vehicle, and the driver outputs an output screen. The blind spot is reduced by visually recognizing. Since the CCD camera images the surroundings by being sensitive to electromagnetic waves such as visible light, it can be imaged by sunlight in the daytime. However, when the surroundings are dark, such as at night, and there is little visible light such as sunlight, it is difficult for the CCD camera to respond, so it is very difficult to take an image. Therefore, in a conventional vehicle periphery imaging device, a vehicle periphery night vision lamp (see, for example, Patent Document 1) is provided so that an image can be captured even when the periphery of the vehicle is dark.

  This vehicle peripheral night vision lamp irradiates an electromagnetic wave having a predetermined frequency, that is, an infrared ray to a range where the CCD camera captures an image. On the other hand, the vehicle peripheral imaging device reduces the blind spot by imaging the range irradiated with infrared rays with a CCD camera that is sensitive to electromagnetic waves in the infrared region, and outputting it to the output screen for visual recognition by the driver. To do.

JP 2002-240629 A

  In the vehicle peripheral night vision lamp, an infrared light emitting diode (infrared LED) is used to emit infrared light. When an infrared LED having a frequency away from the visible light region is used as the infrared LED so as not to irradiate electromagnetic waves in the visible light region, the CCD camera has low sensitivity to infrared light of this frequency. For this reason, an infrared LED having a frequency away from the visible light region is not suitable as a vehicle peripheral night vision lamp. On the other hand, when an infrared LED that emits infrared light close to the visible light region is used as the infrared LED, the sensitivity of the CCD camera with respect to infrared light of this frequency is improved. For this reason, infrared LED which irradiates infrared rays close to the visible light region is suitable as a vehicle peripheral night vision lamp. Here, it is legally regulated that red light cannot be used except for a stop lamp and a tail lamp in a vehicle lamp.

  However, since the infrared LED suitable as a vehicle peripheral night vision lamp emits infrared light close to the visible light region, the red light from the infrared LED can be visually recognized from the outside. Therefore, in order to prevent the infrared light from being visually recognized from the outside, it is conceivable to pass the irradiation light from the infrared LED through a visible light cut filter. However, when this visible light cut filter is used, visible light, that is, the red light is cut, but the infrared output to the outside is also significantly reduced.

  Therefore, the present invention has been made in view of the above, and is a vehicle peripheral night vision lamp that cannot visually recognize red light from the outside and does not reduce infrared output, and the vehicle. It is an object of the present invention to provide a vehicle outside mirror device provided with both a peripheral night vision lamp and a vehicle peripheral imaging device.

  In order to solve the above-described problems and achieve the object, a vehicle peripheral night vision lamp according to the present invention includes infrared irradiation means for irradiating infrared light and visible light irradiation means for irradiating visible light. It is characterized by.

  In the present invention, the vehicle peripheral night vision lamp is used when the vehicle peripheral imaging device is used in a dark environment such as at night. When the vehicle peripheral night vision lamp is used, Irradiate infrared rays and irradiate visible light from the visible light irradiation means. These infrared rays and visible light are irradiated while being mixed with each other because the irradiation directions are approximate. For this reason, even when red light is included in the irradiation light from the infrared irradiation means, the red light cannot be viewed from the outside. Moreover, since red light cannot be visually recognized from the outside in this way, the output of an infrared irradiation means can be raised and more infrared rays can be irradiated. As a result, it is possible to provide a vehicle peripheral night vision lamp that makes it difficult to visually recognize red light from the outside without reducing the infrared output.

  In the vehicle peripheral night vision lamp according to the present invention, the irradiation range of the infrared irradiation unit is included in the irradiation range of the visible light irradiation unit.

  In this invention, since the irradiation range of the infrared irradiation means is included in the irradiation range of the visible light irradiation means, all the irradiation light from the infrared irradiation means can be mixed with the irradiation light from the visible light irradiation means. . For this reason, even when red light is included in the irradiation light from the infrared irradiation means, the red light can be reliably mixed with the visible light from the visible light irradiation means. As a result, the red light from the infrared irradiation means can be more reliably made difficult to visually recognize.

  The vehicle outside mirror device according to the present invention includes a vehicle peripheral imaging device that images a blind spot range of the vehicle, a vehicle peripheral night vision lamp that irradiates infrared and visible light to the imaging range of the vehicle peripheral imaging measure, and , Provided.

  In this invention, since the vehicle peripheral night vision lamp includes the infrared irradiation means and the visible light irradiation means, it is difficult to visually recognize the red light from the outside without reducing the infrared output. It can be a lamp. In particular, in the present invention, the vehicle outside mirror device is provided with both the vehicle periphery imaging device and the vehicle periphery night vision lamp, so that the vehicle can be visually recognized over a wide range of blind spots.

  The vehicle peripheral night vision lamp according to the present invention has an effect that it is difficult to visually recognize red light from the outside. Moreover, since it is difficult to visually recognize red light, it is possible to increase the output of the infrared irradiation means and to irradiate more infrared rays. Further, the vehicle outside mirror device according to the present invention makes it difficult to visually recognize red light, and does not reduce the output of infrared rays. Moreover, the vehicle can visually recognize the blind spot range over a wide range. Can do.

  Embodiments of a vehicle peripheral night vision lamp and a vehicle outside mirror device according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments. In addition, constituent elements in the following embodiments include those that can be easily replaced by those skilled in the art or those that are substantially the same.

  In the following description, the front of the vehicle when the vehicle peripheral night vision lamp of the present invention is mounted on the vehicle will be described as the front in the vehicle peripheral night vision lamp, and the opposite side will be described as the rear. Similarly, the upper part of the vehicle will be described as the upper part of the vehicle peripheral night-vision lamp, and the opposite side will be described as the lower part. Note that the vehicle peripheral night vision lamp described below describes the vehicle peripheral night vision lamp equipped on the left side of the vehicle in the traveling direction of the vehicle, and the vehicle periphery equipped on the right side of the vehicle. The night vision lamp is substantially symmetrical with the illustrated vehicle peripheral night vision lamp. FIG. 1 is a side view of a vehicle including a vehicle peripheral night vision lamp according to an embodiment of the present invention. FIG. 2 is a perspective view of a vehicle outside mirror including a vehicle peripheral night vision lamp according to an embodiment of the present invention. FIG. 3 is a front view of the vehicle outside mirror including the vehicle peripheral night vision lamp according to the embodiment of the present invention. 4 is a cross-sectional view taken along the line AA in FIG.

  A vehicle peripheral night vision lamp 30 shown in FIG. 1 is provided in a vehicle outside mirror 10 provided in the vehicle 1. The vehicle outside mirror 10 is attached to the doors of the driver's seat and the passenger seat of the vehicle 1 as a door mirror. Further, the driver's seat of the vehicle 1 is provided on the right side in the traveling direction of the vehicle 1. Of the vehicle outside mirror 10 equipped in the vehicle 1, the side away from the driver's seat, that is, The left vehicle outside mirror 10 is provided with a vehicle periphery imaging device 20. The vehicle peripheral night vision lamp 30 is provided on the vehicle outside mirror 10 on the side where the vehicle peripheral imaging device 20 is provided. Thus, the vehicle outside mirror 10 provided with the vehicle periphery night vision lamp 30 together with the vehicle periphery imaging device 20 is formed as a vehicle outside mirror device.

  The vehicle periphery imaging device 20 is provided in the outer case 11 of the vehicle outside mirror 10, and images a predetermined direction from a portion opened in front of the outer case 11. The vehicle periphery imaging device 20 is provided with a CCD camera 21, and the lens of the CCD camera 21 is directed from the opened portion of the outer case 11 toward the left front wheel 5 of the vehicle 1 as described above. Yes. In the vehicle periphery imaging device 20, an image display device (not shown) provided near the driver's seat in the vehicle and the CCD camera 21 are electrically connected by a harness or the like.

  The vehicle peripheral night vision lamp 30 is provided in the vehicle outside mirror 10 on the side where the vehicle peripheral imaging device 20 is provided, and is provided in the vicinity of the vehicle peripheral imaging device 20. Specifically, the vehicle peripheral night vision lamp 30 is provided adjacent to the inside of the vehicle peripheral imaging device 20 in the width direction of the vehicle 1. An opening 12 for the vehicle peripheral night vision lamp 30 is formed in the outer case 11 of the vehicle outside mirror 10. The vehicle peripheral night vision lamp 30 is provided in the vicinity of the opening 12 inside the outer case 11.

  A diffuser lens 31 is provided in the opening 12. The diffusing lens 31 is made of a colorless transparent or colored transparent resin, and has a surface on one side or both sides having irregularities such as a prism shape. The diffusing lens 31 having such irregularities is fitted into the opening 12. Further, an infrared LED 32 that is an infrared irradiation unit and a white LED 35 that is a visible light irradiation unit are provided inside the opening 12. A plurality of these infrared LEDs 32 and white LEDs 35 are provided.

  The infrared LEDs 32 are formed in a total of six, two rows in the vertical direction and three rows in the horizontal direction. The direction of the infrared LED 32 is such that the glass bulb 33 side of the infrared LED 32 is forward and the connecting portion 34 is rearward. The white LED 35 is provided outside the infrared LED 32 in the width direction of the vehicle 1. Specifically, the two white LEDs 35 are formed on the outer side of the infrared LED 32 in the width direction of the vehicle 1 in two stages having the same height in the vertical direction as the infrared LED 32. As with the infrared LED 32, the direction is such that the glass bulb 36 side is the front and the connecting portion 37 is the rear.

  The positions of these infrared LEDs 32 and white LEDs 35 in the front-rear direction are formed in accordance with the shape of the outer case 11 of the vehicle outside mirror 10. Specifically, since the outer case front surface 13 is formed in a shape that curves from the front to the rear as it goes from the inner side in the width direction of the vehicle 1 to the outer side, the infrared LED 32 is matched to the shape. And white LED35 is arrange | positioned. That is, as for infrared LED32 and white LED35, what is formed in the width direction outer side of the vehicle 1 is located back rather than what is formed inside. The infrared LED 32 and the white LED 35 are formed at the positions as described above, and the irradiation range of the infrared LED 32 is included in the irradiation range of the white LED 35.

  FIG. 5 is a diagram illustrating the characteristics of the infrared LED 32, the white LED 35, and the CCD camera 21 used in the vehicle imaging device 20 used in the vehicle peripheral night vision lamp 30 of the present embodiment. The horizontal direction in FIG. 5 represents the wavelength of the electromagnetic wave, and the wavelength becomes longer toward the right. The vertical direction represents the relative sensitivity to the wavelength in the horizontal direction, or the relative amount of electromagnetic waves at that wavelength, and the sensitivity increases or the relative amount increases as it goes up. It has become. As shown in FIG. 5, in the vicinity of the boundary between the visible region 41 and the infrared region 42, the infrared region 42 has a wavelength of 780 nm or more and the visible region 41 has a wavelength of 780 nm or less. When the naked eye senses the electromagnetic wave in the visible region 41, the electromagnetic wave in this region can be visually recognized. The electromagnetic wave in the visible region 41 is called so-called visible light.

  The infrared LED 32 used in the present embodiment has a wavelength of 800 nm to 900 nm within the infrared region 42 in the irradiation light irradiated by the infrared LED 32 as indicated by the infrared LED irradiation characteristic line 45. There is a peak of the irradiation amount of infrared rays between them, and infrared rays having the peak wavelength are irradiated most. As the wavelength becomes longer or shorter than the peak wavelength, the amount of irradiated infrared light generally decreases. Moreover, although the amount of infrared rays also decreases as the wavelength becomes shorter, the infrared LED 32 also irradiates some irradiation light with a wavelength of 780 nm or less. Since the irradiation light of this part is irradiation light of the visible region 41, this irradiation light becomes visible light, specifically, red light. As described above, the infrared LED 32 emits a small amount of red light while irradiating a large amount of infrared rays.

  As shown by the white LED irradiation characteristic line 46, the white LED 35 used in the present embodiment is visible light within a wavelength range of 400 nm to 500 nm that is within the visible region 41 in the irradiation light irradiated by the white LED 35. There is a peak of the irradiation amount, and the irradiation light with the wavelength of this peak is irradiated most. As the wavelength becomes longer or shorter than the peak wavelength, the amount of visible light irradiated generally decreases, and the irradiation amount becomes 0 near the boundary with the infrared region 42 in the visible region 41. Become. For this reason, the white LED 35 irradiates a large amount of visible light, but does not irradiate electromagnetic waves in the infrared region 42, that is, infrared rays.

  The CCD camera 21 used in the vehicle periphery imaging device 20 has the highest sensitivity due to electromagnetic waves in the range of 500 nm to 600 nm within the visible region 41 as indicated by the CCD camera sensitivity characteristic line 47. . As the wavelength becomes shorter or longer than the portion with the highest sensitivity, the sensitivity generally decreases, and the electromagnetic wave having the wavelength in the infrared region 42 has sensitivity. For this reason, the sensitivity in the infrared region 42 is higher on the visible region 41 side of the infrared region 42, and the sensitivity becomes lower as the wavelength becomes longer. As described above, the CCD camera 21 has the sensitivity in the infrared region 42 while the sensitivity becomes lower as the wavelength becomes longer.

  The vehicle peripheral night vision lamp 30 according to this embodiment is configured as described above, and the operation thereof will be described below. When the vehicle 1 equipped with the vehicle night vision lamp 30 is used to visually recognize the situation in the vicinity of the front wheel that is a blind spot range from the driver's seat via the vehicle peripheral imaging device 20 at night or the like, The imaging device 20 captures the blind spot range, and the vehicle peripheral night vision lamp 30 irradiates the imaging range. Specifically, in the case of the vehicle 1 described above, the vehicle periphery imaging device 20 and the vehicle periphery night vision lamp 30 are provided in the vehicle outside mirror 10 on the left side of the vehicle 1. Reference numeral 20 images the vicinity of the left front wheel 5 that is a blind spot range from the driver's seat, and the vehicle peripheral night vision lamp 30 irradiates the vicinity of the left front wheel 5 that is an imaging range of the vehicle peripheral imaging device 20.

  This irradiation is performed in conjunction with a switch (not shown) of the clearance lamp of the vehicle 1 or a switch (not shown) of the vehicle periphery imaging device 20 or by an independent manual switch (not shown). The visual lamp 30 is turned on and irradiated. When the vehicle peripheral night vision lamp 30 is lit, the infrared LED 32 and the white LED 35 are lit. This infrared LED 32 irradiates infrared rays as described above. The irradiated infrared light is irradiated to the outside while being diffused by the diffusion lens 31. The infrared rays irradiated to the outside irradiate the vicinity of the left front wheel 5. Thus, when the infrared LED 32 irradiates, most of the irradiation is infrared, but as indicated by the infrared LED irradiation characteristic line 45, both red light and irradiation are slightly irradiated.

  FIG. 6 is a diagram when the vehicle peripheral night-vision lamp of this embodiment is turned on. Further, when the white LED 35 is turned on, visible light is irradiated. This visible light is also diffused by the diffusing lens 31 and irradiated to the outside like the infrared rays of the infrared LED 32. The irradiation range of the white LED 35 includes the irradiation range of the infrared LED 32. For this reason, the irradiation light from the infrared LED 32 is mixed with the irradiation light from the white LED 35. Further, since both irradiation lights are diffused by the diffusion lens 31, they are further mixed while being diffused by the diffusion lens 31. Thus, when the vehicle peripheral night vision lamp 30 is turned on, the irradiation light from the infrared LED 32 and the white LED 35 is mixed and further diffused by the diffusion lens 31, so that the infrared LED 32 is slightly irradiated. The red light is confused with the visible light from the white LED 35 and is not visible from the outside. Further, since both irradiation lights are diffused by the diffusion lens 31, the entire diffusion lens 31 is turned on without irradiating a predetermined position.

  The infrared light emitted from the infrared LED 32 illuminates the vicinity of the left front wheel 5 as described above, and the vicinity of the left front wheel 5 is also an imaging range by the vehicle periphery imaging device 20. The CCD camera 21 provided in the vehicle periphery imaging device 20 has a sensitivity in the infrared region 42 as indicated by the CCD camera sensitivity characteristic line 47. For this reason, even when the surroundings of the vehicle 1 are dark, the vehicle periphery imaging device 20 can image the vicinity of the left front wheel 5 irradiated with infrared rays.

  Since the above-described vehicle peripheral night-vision lamp 30 lights the infrared LED 32 and the white LED 35 at the same time, the red light slightly emitted from the infrared LED 32 is diverted into visible light emitted from the white LED 35. be able to. As a result, since the red light cannot be visually recognized from the outside, the infrared LED 32 including the red light in the irradiated light can be used in a portion where the red light cannot be irradiated in accordance with the law. Even when the irradiation light includes red light, it is not necessary to reduce the infrared output. Moreover, since red light cannot be visually recognized from the outside, the output of the infrared LED 32 that includes red light in the irradiation light can be increased. As a result, since the amount of infrared irradiation increases, the visibility by imaging with the vehicle periphery imaging device 20 at night increases, so the safety during driving of the vehicle 1 improves.

  Further, since red light cannot be visually recognized from the outside, when using the CCD camera 21 having a high sensitivity in the infrared region 42 near the visible region 41, the irradiation light includes red light, and the irradiation property is visible region 41. A near infrared LED 32 can be used. As a result, the high-sensitivity portion of the CCD camera 21 in the infrared region 42 and the portion where the infrared LED 32 has a large amount of infrared irradiation are both close to the visible region 41. As a result, when the subject is irradiated with infrared rays, the sensitivity at the time of imaging with the CCD camera 21 is improved, so that the visibility by imaging with the vehicle peripheral imaging device 20 at night is improved, and the vehicle 1 Safety during driving is improved.

  Further, as described above, red light cannot be visually recognized from the outside by irradiation with visible light, so that the infrared LED 32 having an irradiation characteristic closer to the visible region 41 can be used. 41 having a high sensitivity characteristic can be used. As a result, it is possible to improve the visibility in the vehicle periphery imaging device 20 when the surroundings are bright such as daytime, that is, when visible light is irradiated from the outside. Further, by using the infrared LED 32 as the infrared irradiation means and using the white LED 35 as the visible light irradiation means, it is possible to reduce the power consumption during the irradiation of infrared rays and visible light.

  In addition, arrangement | positioning other than said Example may be sufficient as arrangement | positioning of infrared LED32 and white LED35. For example, as shown in FIG. 7, the vehicle peripheral night vision lamp 60 is provided in the outer case 11 of the vehicle outside mirror 10 in the same manner as the vehicle peripheral night vision lamp 30 of the embodiment. In the vehicle peripheral night-vision lamp 60 in this state, as shown in FIG. 8, the infrared LED 61 is arranged in the same direction as the infrared LED 32 of FIG. 4, and the white LED 62 has a glass bulb 63 in the outward direction of the vehicle 1. In addition, the connection portion 64 may be disposed in the direction toward the inner side of the vehicle 1. Even if the irradiation direction of the infrared LED 61 and the irradiation direction of the white LED 62 are different, the diffuser lens 65 is provided in the vehicle peripheral night vision lamp 60, so that the irradiation light of the infrared LED 61 and the irradiation of the white LED 62 are provided. Both the light and the light are diffused by the diffusion lens 65. Thereby, since the red light contained in the irradiation light from the infrared LED 61 is mixed with the irradiation light from the white LED 62, this red light cannot be visually recognized from the outside. As a result, it is possible to irradiate infrared rays in a predetermined direction without observing red light from the vehicle outside mirror 10 which is a portion that cannot emit red light according to the law. Further, since the red light cannot be visually recognized, it is not necessary to reduce the output of the infrared LED 61 in consideration of the red light, and it is possible to irradiate the amount of infrared rays required for night imaging of the vehicle peripheral imaging device 20. As a result, the safety when driving the vehicle 1 at night is improved.

  Thus, since the diffuser lens 31 is provided in the vehicle peripheral night vision lamp 30, the arrangement of the infrared LED 32 and the white LED 35 is included in the irradiation light of the infrared LED 32 even if the arrangement is other than the embodiment. The red light is mixed with visible light from the white LED 35, and the same effect as in the embodiment can be obtained. In short, if the configuration is such that the irradiation light from the infrared LED 32 and the irradiation light from the white LED 35 are mixed when irradiated to the outside, the red light from the infrared LED 32 is white. Since it is obscured by visible light from the LED 35, it is not necessary to reduce the output of the infrared LED 32, or the output can be improved, so that a sufficient amount of infrared rays can be irradiated in a predetermined direction.

  Further, when the range of the infrared irradiation angle of the infrared LED 32 is made narrower than the range of the visible light irradiation angle of the white LED 35, the range of visible light irradiated from the white LED 35 by the infrared ray irradiated from the infrared LED 32. The red light is more difficult to see with certainty.

  Moreover, since the vehicle outside mirror device in this embodiment is provided with both the vehicle periphery imaging device and the vehicle periphery night vision lamp, it is possible to visually recognize the image over a wide range of the blind spot of the vehicle.

  In the above description, the driver's seat is provided on the right side in the traveling direction of the vehicle 1, and together with the vehicle peripheral imaging device 20 provided on the left vehicle outside mirror 10, the left vehicle outside mirror 10 is provided. Although the vehicle periphery night vision lamp 30 provided is described, the vehicle periphery night vision lamp 30 of the present invention may be provided in the right vehicle outside mirror 10 together with the vehicle periphery imaging device 20. By providing the vehicle peripheral night vision lamp 30 according to the present invention at a position close to the vehicle peripheral imaging device 20, it is possible to irradiate infrared rays to the imaging range of the vehicle peripheral imaging device 20, and further, irradiation of the vehicle peripheral night vision lamp 30. Since red light is sometimes not visible, even when the emission of red light from this portion is prohibited by laws and regulations, it is not necessary to reduce the output of the infrared LED 32 including red light. As a result, visibility at night and the like by the vehicle periphery imaging device 20 is improved, and safety during driving of the vehicle 1 is improved.

  Further, the vehicle peripheral night vision lamp 30 according to the present invention may be provided in a portion other than the vehicle outside mirror 10. Even in a portion other than the vehicle outside mirror 10, by providing the vehicle peripheral night vision lamp 30 at a position where the imaging portion of the vehicle peripheral imaging device 20 can be irradiated with infrared rays, the vehicle 1 in a situation where the surroundings are dark such as at night. The driving safety can be improved. As a result, the degree of freedom in designing the vehicle 1 including the vehicle peripheral night vision lamp 30 is improved.

  As described above, the vehicle peripheral night vision lamp and the vehicle outside mirror device according to the present invention are dark at night when the part that cannot be directly viewed from the driver's seat is visually recognized by the vehicle peripheral imaging device or the like. This is useful for visual recognition in the environment, and is particularly suitable for cases where red light is prohibited from being emitted from the vehicle peripheral night vision lamp to the outside by laws and regulations.
