請求項４に係る発明では、照明手段の光源は、指向性のある発光ダイオードであることを特徴とする。 The invention according to claim 4 is characterized in that the light source of the illumination means is a directional light emitting diode.

請求項１に係る発明では、車両の後方を映す鏡とこの鏡の近傍に配置して下方を照らす照明手段を取付けたアウトサイドミラー装置において、鏡の下に車両の外側下方を映す透明部材を配置し、この透明部材は、下方に向ける入光面を形成し、運転者に向ける出光面を形成し、出光面の対向側に反射部材を一体的に取付けてなる反射鏡面が運転者に対して形成されたもので、照明手段は、透明部材をレンズとして用い、照明光を反射鏡面で反射させた後、入光面から照射するので、透明部材で映す範囲内で特定位置を照らすことができる。その結果、透明部材を照明用のレンズと兼用することができ、車両の外側下方を映すミラーと車両の外側下方を照らす照明手段を備えても、部品点数を削減することができる。 In the invention according to claim 1, in the outside mirror device in which the mirror that reflects the rear of the vehicle and the illumination unit that is disposed in the vicinity of the mirror and illuminates the lower part is attached, the transparent member that reflects the lower outside of the vehicle is provided below the mirror.

Then, since the light is incident from the light incident surface, the area illuminated by the reflecting mirror surface is wide, so that a dedicated illumination member for illuminating the wide area is not required, and the number of parts can be suppressed.

また、反射鏡面で反射させると、照らす領域は広範囲となるから、照明手段をよりコンパクトに設けることができ、結果的に、照明手段を設けてもアウトサイドミラー装置の小型化を図ることができる。 Moreover, since the area to illuminate becomes wide when reflected by the reflecting mirror surface, the illumination means can be provided more compactly.

This transparent member forms a light entrance surface directed downward, forms a light exit surface directed toward the driver, and a reflecting mirror surface formed by integrally attaching a reflective member on the opposite side of the light exit surface is provided to the driver. The illumination means uses a transparent member as a lens, includes a condenser lens, and irradiates illumination light condensed by the condenser lens outward from the light incident surface. Illumination light in a desired condensing state can be obtained by condensing light and diffusing the light incident surface, and a specific position within a range reflected by the transparent member can be illuminated with a pinpoint.

また、照明手段は、集光レンズを備え、この集光レンズで集光した照明光を入光面から外方に照射するので、集光した照明光を反射鏡面を介さずに直接、下方の対象位置に照射することができ、集光レンズ、透明部材の形状にて照明範囲を容易に設定することができる。 Further, the illumination means includes a condensing lens, and irradiates the illumination light condensed by the condensing lens outward from the light incident surface, so that the condensed illumination light is directly below the reflecting mirror surface without passing through the reflecting mirror surface. The target position can be irradiated, and the illumination range can be easily set by the shape of the condenser lens and the transparent member.

請求項４に係る発明では、照明手段の光源は、指向性のある発光ダイオードである。指向性のある発光ダイオードを用いることによって、透明部材の形状、例えば入光面の凹形状に伴う拡散で所望の範囲まで照明の範囲を広げることができ、照明範囲の設定は容易になる。 In the invention according to claim 4 , the light source of the illumination means is a directional light emitting diode. By using a directional light emitting diode, the illumination range can be expanded to a desired range by diffusion associated with the shape of the transparent member, for example, the concave shape of the light incident surface, and the illumination range can be easily set.

照明手段は、発光ダイオードを採用することで、光源を支持するホルダ部も小型になり、ホルダ部及び光源を極めて小さくすることができ、結果的に、自身（照明手段）が小型になるという利点がある。 The illumination means employs a light emitting diode, so that the holder part for supporting the light source can be made small, and the holder part and the light source can be made extremely small. As a result, the self (illumination means) becomes small. There is.

FIG. 7 is an operation diagram of the outside mirror device of the present invention, schematically showing. First, the case where the lens part (convex lens) 26 is not formed will be described, and then the state when the lens part (convex lens) 26 is formed will be described.

照明手段１７を点灯すると、照明手段１７から発光する照明光６１は、ほぼ一直線状に進行した後、入光面２８の凹面形状によって拡散する。
このように、下方を照らす照明手段１７を取付けたアウトサイドミラー装置１１では、照明手段１７は、透明部材１６をレンズとして用い、入光面２８から照明光を照射するので、透明部材１６で映す範囲内で特定位置を照らすことができる。その結果、透明部材１６を照明用のレンズと兼用することができ、車両１１の外側下方を映すミラー（後方ミラー）１５と車両１１の外側下方を照らす照明手段１７を備えても、部品点数を削減することができる。 When the illuminating means 17 is turned on, the illumination light 61 emitted from the illuminating means 17 travels substantially in a straight line and then diffuses due to the concave shape of the light incident surface 28.
As described above, in the outside mirror device 11 to which the illuminating means 17 for illuminating the lower side is attached, the illuminating means 17 uses the transparent member 16 as a lens and irradiates illumination light from the light incident surface 28. A specific position can be illuminated within the range. As a result, the transparent member 16 can also be used as an illumination lens, and even if the mirror (rear mirror) 15 that reflects the lower outside of the vehicle 11 and the illumination means 17 that illuminates the lower outside of the vehicle 11 are provided, the number of parts can be reduced. Can be reduced.

また、アウトサイドミラー装置１１では、透明部材１６をレンズとして用い、入光面２８から照明光を照射するので、透明部材１６を照明用のレンズと兼用することができ、照明用のレンズを必要としない。その結果、車両１１の外側下方を映すミラー（後方ミラー）１５と車両１１の外側下方を照らす照明手段１７を備えても、照明手段１７の小型化を図ることができ、結果的に、アウトサイドミラー装置１１の小型を図ることができる。 Further, in the outside mirror device 11, since the transparent member 16 is used as a lens and the illumination light is irradiated from the light incident surface 28, the transparent member 16 can be used also as an illumination lens, and an illumination lens is necessary. And not. As a result, even if the mirror (rear mirror) 15 that reflects the outside lower side of the vehicle 11 and the illumination unit 17 that illuminates the lower side outside the vehicle 11 are provided, the illumination unit 17 can be reduced in size, and as a result, the outside side The mirror device 11 can be downsized.

次にレンズ部（凸レンズ）２６を形成した場合について説明する。
アウトサイドミラー装置１１の照明手段１７を点灯すると、照明手段１７から発光する照明光６１は、ほぼ一直線状に進行した後、レンズ部（凸レンズ）２６によって屈折することで、集光し、集光照明光６２となる。集光照明光６２は透明部材１６を通った後、入光面２８の凹面形状によって拡散し、集光照明光６３，６４となって下方を照らす。 Next, the case where the lens part (convex lens) 26 is formed will be described.
When the illuminating means 17 of the outside mirror device 11 is turned on, the illumination light 61 emitted from the illuminating means 17 travels in a substantially straight line, and then is refracted by the lens portion (convex lens) 26 to be condensed and condensed. It becomes bright light 62. After the condensed illumination light 62 passes through the transparent member 16, it is diffused by the concave shape of the light incident surface 28, and becomes the condensed illumination light 63 and 64 to illuminate the lower part.

その結果、集光照明光６３，６４によって、透明部材１６で映す範囲内で特定位置をピンポイントで照らすことができる。従って、暗いときでも、車両１２の左外側下方に位置する対象物を映すことができる。 As a result, the specific position can be pinpointed within the range reflected by the transparent member 16 by the condensed illumination lights 63 and 64. Therefore, even when it is dark, an object located on the lower left outside of the vehicle 12 can be projected.

このように、照明手段１７は、集光レンズ（レンズ部）２６を備え、この集光レンズ２６で集光した照明光６２を入光面２８から外方に照射するので、集光レンズ２６の集光と入光面２８の拡散とによって所望の集光状態の照明光（集光照明光）６３，６４を得ることができ、車両１１の外側下方を映すミラー（後方ミラー）１５と車両１１の外側下方を照らす照明手段１７を備えても、部品点数を削減することができる。 As described above, the illumination unit 17 includes the condenser lens (lens portion) 26 and irradiates the illumination light 62 condensed by the condenser lens 26 outward from the light incident surface 28. Illumination light (condensed illumination light) 63 and 64 in a desired condensing state can be obtained by condensing and diffusion of the light incident surface 28, and a mirror (rear mirror) 15 that reflects the lower outside of the vehicle 11 and the vehicle 11 Even if the illumination means 17 for illuminating the outside lower side is provided, the number of parts can be reduced.

また、照明手段１７は、集光レンズ（レンズ部）２６を備え、この集光レンズ２６で集光した照明光（集光照明光）６３，６４を入光面２８から外方に照射するので、集光した照明光６３，６４を反射鏡面３３を介さずに直接、下方の対象位置に照射することができ、照明範囲の設定が容易になる。 Further, the illumination means 17 includes a condenser lens (lens portion) 26 and irradiates illumination light (condensed illumination light) 63 and 64 condensed by the condenser lens 26 outward from the light incident surface 28. The condensed illumination lights 63 and 64 can be directly applied to the target position below without passing through the reflecting mirror surface 33, and the setting of the illumination range is facilitated.

図２に示すように、アウトサイドミラー装置１１では、照明手段１７は、下部保持部２３の上部に成形したホルダ部２４と、ホルダ部２４に嵌合した発光体２５とからなり、部品点数は２点であり、部品点数を削減することができる。 As shown in FIG. 2, in the outside mirror device 11, the illuminating means 17 includes a holder part 24 formed on the upper part of the lower holding part 23 and a light emitter 25 fitted to the holder part 24. The number of parts can be reduced.

発光体２５は、指向性のある発光ダイオード２７である。指向性のある発光ダイオード（ＬＥＤ）２７を用いることによって、透明部材１６の形状（入光面２８の凹形状）に伴う拡散で所望の範囲まで照明の範囲を広げることができ、照明範囲の設定は容易になる。 The light emitter 25 is a directional light emitting diode 27. By using the light-emitting diode (LED) 27 having directivity, the illumination range can be expanded to a desired range by diffusion associated with the shape of the transparent member 16 (concave shape of the light incident surface 28). Becomes easier.

照明手段１７は、下部保持部２３の上部に成形したホルダ部２４と、ホルダ部２４に嵌合した発光体２５とからなり、発光体２５に発光ダイオード２７を採用することで、ホルダ部２４及び発光体２５を極めて小さくすることができる。 The illuminating means 17 includes a holder part 24 formed on the upper part of the lower holding part 23 and a light emitter 25 fitted to the holder part 24. By using a light emitting diode 27 for the light emitter 25, the holder part 24 and The light emitter 25 can be made extremely small.

照明手段１７では、下部保持部２３の上部にホルダ部２４を成形すると、下部保持部２３を成形する際に一体でホルダ部２４を成形することができ、ホルダ部２４の成形に手間がかからない。 In the illuminating means 17, if the holder part 24 is formed on the upper part of the lower holding part 23, the holder part 24 can be integrally formed when the lower holding part 23 is formed, and it takes less time to form the holder part 24.

透明部材１６では、反射部材３２を一体的に取付けてなる反射鏡面３３を運転者Ｍに対して凸面で形成したので、反射鏡面３３は運転者Ｍ（図２参照）に対して凸面鏡と同等の作用をなし、対象物からの反射光線５１，５２の入光する角度λ１は大きくなり、映す対象の範囲を広くすることができる。 In the transparent member 16, the reflecting mirror surface 33 formed by integrally attaching the reflecting member 32 is formed as a convex surface with respect to the driver M. Therefore, the reflecting mirror surface 33 is equivalent to the convex mirror with respect to the driver M (see FIG. 2). The angle .lamda.1 at which the reflected light beams 51 and 52 from the object are incident increases, and the range of the object to be projected can be widened.

透明部材１６では、入光面２８は、凹面形状に形成した部位なので、入光面２８は凹レンズと同等の作用をなし、対象物からの反射光線６５，６６の入光する角度λ２（λ２＞λ１）はより大きくなり、透明部材１６を大きくすることなく映す対象の範囲をより広くすることができる。 In the transparent member 16, since the light incident surface 28 is a portion formed in a concave shape, the light incident surface 28 has the same function as a concave lens, and the angle λ2 (λ2>) at which the reflected light beams 65 and 66 from the object are incident. λ1) becomes larger, and the range of objects to be projected can be made wider without enlarging the transparent member 16.

次に、本発明のアウトサイドミラー装置の別の形態を説明する。
図８は、図２の別の実施の形態図であり、上記図２に示す実施の形態と同様の構成については、同一符号を付し説明を省略する。 Next, another embodiment of the outside mirror device of the present invention will be described.
FIG. 8 is another embodiment of FIG. 2, and the same components as those in the embodiment shown in FIG.

別の実施の形態の照明手段１７Ｂは、反射鏡面３３に照明光を向けたもので、下部保持部２３の上部に成形したホルダ部２４Ｂと、ホルダ部２４Ｂに嵌合した発光体２５とからなる。
また、照明手段１７Ｂは、透明部材１６に成形したレンズ部２６Ｂを有する。
レンズ部２６Ｂは、透明部材１６の上面３７に凸に形成した集光レンズで、焦点をＦｂの位置に設定した。 The illumination means 17B according to another embodiment has illumination light directed to the reflecting mirror surface 33, and includes a holder part 24B formed on the upper part of the lower holding part 23 and a light emitter 25 fitted to the holder part 24B. .
The illumination unit 17B has a lens portion 26B formed on the transparent member 16.
The lens portion 26B is a condensing lens formed convexly on the upper surface 37 of the transparent member 16, and the focal point is set at the position Fb.

次に別の実施の形態の作用を説明する。
図９は、別の実施の形態の作用図であり、模式的に示す。上記図２、図７に示す実施の形態と同様の構成については、同一符号を付し説明を省略する。
まず、レンズ部（凸レンズ）２６を形成しない場合を説明し、その後に、レンズ部（凸レンズ）２６を形成したときの状態を説明する。 Next, the operation of another embodiment will be described.
FIG. 9 is an operation diagram of another embodiment, which is schematically shown. The same components as those in the embodiment shown in FIGS. 2 and 7 are given the same reference numerals and description thereof is omitted.
First, the case where the lens part (convex lens) 26 is not formed will be described, and then the state when the lens part (convex lens) 26 is formed will be described.

照明手段１７Ｂを点灯すると、照明手段１７Ｂから発光する照明光６７は、ほぼ一直線状に進行した後、反射鏡面３３で反射する。この反射した照明光６７は入光面２８から外方に進行する。その際、反射した照明光６７は入光面２８の凹面形状によって拡散する。 When the illuminating means 17B is turned on, the illumination light 67 emitted from the illuminating means 17B travels in a substantially straight line and is then reflected by the reflecting mirror surface 33. The reflected illumination light 67 travels outward from the light incident surface 28. At this time, the reflected illumination light 67 is diffused by the concave shape of the light incident surface 28.

このように、別の実施の形態のアウトサイドミラー装置１１Ｂでは、透明部材１６には、出光面３１の対向側（図２の矢印ａ５の方向）に反射部材３２を一体的に取付けてなる反射鏡面３３が運転者Ｍ（図２参照）に対して形成され、照明手段１７Ｂは、照明光を反射鏡面３３で反射させた後、入光面２８から照射するように配置したので、反射鏡面３３によって照らす領域は広範囲となり、広範囲を照らすための専用の照明部材を必要とせず、部品点数を抑制することができる。 As described above, in the outside mirror device 11B according to another embodiment, the transparent member 16 has a reflection member 32 integrally attached to the opposite side of the light exit surface 31 (in the direction of arrow a5 in FIG. 2). The mirror surface 33 is formed for the driver M (see FIG. 2), and the illuminating means 17B is arranged so that the illumination light is reflected by the reflecting mirror surface 33 and then irradiated from the light incident surface 28. The area illuminated is wide, and a dedicated illumination member for illuminating the wide area is not required, and the number of parts can be suppressed.

また、反射鏡面３３で反射させると、照らす領域は広範囲となるから、照明手段１７Ｂをよりコンパクトに設けることができ、結果的に、照明手段１７Ｂを設けてもアウトサイドミラー装置１１Ｂの小型化を図ることができる。 Moreover, since the area to illuminate becomes wide when reflected by the reflecting mirror surface 33, the illumination means 17B can be provided more compactly. As a result, the outside mirror device 11B can be downsized even if the illumination means 17B is provided. Can be planned.

反射鏡面３３で反射させると、照らす領域は広範囲となるから、照明手段１７Ｂをよりコンパクトに設けることができ、アウトサイドミラー装置１１Ｂのデザインの自由度を高めることができる。 When the light is reflected by the reflecting mirror surface 33, the area to be illuminated becomes wide, so that the illumination means 17B can be provided more compactly, and the degree of freedom in designing the outside mirror device 11B can be increased.

次にレンズ部（凸レンズ）２６Ｂを形成した場合について説明する。
アウトサイドミラー装置１１Ｂの照明手段１７Ｂを点灯すると、照明手段１７Ｂから発光する照明光６７は、ほぼ一直線状に進行した後、レンズ部（凸レンズ）２６Ｂによって屈折することで、集光し、集光照明光６８となる。集光照明光６８は反射鏡面３３によって拡散して集光照明光７１となる。この集光照明光７１は透明部材１６Ｂを通った後、入光面２８の凹面形状によって拡散し、集光照明光７２，７２となって下方を照らす。 Next, the case where the lens part (convex lens) 26B is formed will be described.
When the illuminating unit 17B of the outside mirror device 11B is turned on, the illumination light 67 emitted from the illuminating unit 17B travels in a substantially straight line, and then is refracted by the lens unit (convex lens) 26B to be condensed and focused. It becomes bright light 68. The condensed illumination light 68 is diffused by the reflecting mirror surface 33 and becomes the condensed illumination light 71. After this condensed illumination light 71 passes through the transparent member 16B, it is diffused by the concave shape of the light incident surface 28 and becomes the condensed illumination light 72, 72 to illuminate the lower part.

このように、照明手段１７Ｂは、集光レンズ２６Ｂを備え、この集光レンズ２６Ｂで集光した照明光６８を反射鏡面３３によって反射して入光面２８から外方に照射するので、集光レンズ２６Ｂの集光と入光面２８の拡散とによって所望の集光状態の照明光（集光照明光）７２，７２を得ることができ、反射鏡面３３に映る対象位置をピンポイントで照らすことができ、照射効率の向上を図ることができる。 As described above, the illumination unit 17B includes the condensing lens 26B, and the illumination light 68 collected by the condensing lens 26B is reflected by the reflecting mirror surface 33 and radiates outward from the light incident surface 28. Illumination light (condensed illumination light) 72 and 72 in a desired condensing state can be obtained by condensing the lens 26B and diffusion of the light incident surface 28, and a target position reflected on the reflecting mirror surface 33 can be illuminated by a pinpoint. The irradiation efficiency can be improved.

また、反射鏡面３３に映る対象位置をピンポイントで照らすための照明部材を必要とせず、部品点数を抑制することができる。 Moreover, the illumination member for illuminating the target position reflected on the reflective mirror surface 33 with a pinpoint is not required, and the number of parts can be suppressed.

なお、発光体２５を透明部材１６の上面３７に配置したが、発光体２５の配置は任意である。例えば、図５の二点鎖線で示す発光体２５のように、側面３４若しくは側面３５に発光体２５を配置することも可能である。 In addition, although the light emitter 25 is disposed on the upper surface 37 of the transparent member 16, the light emitter 25 is arbitrarily disposed. For example, it is also possible to arrange the light emitter 25 on the side surface 34 or the side surface 35 like the light emitter 25 shown by a two-dot chain line in FIG.

尚、本発明のアウトサイドミラー装置は、実施の形態では四輪車に適用したが、三輪車にも適用可能であり、一般の車両に適用することは差し支えない。 Although the outside mirror device of the present invention is applied to a four-wheeled vehicle in the embodiment, it can also be applied to a three-wheeled vehicle and can be applied to a general vehicle.

本発明のアウトサイドミラー装置は、車両に好適である。 The outside mirror device of the present invention is suitable for vehicles.
