According to the traveling direction display device 1 configured as described above, when the vehicle 2 travels in the direction i, the lamp unit 3x serves as the front lamp unit, the lamp unit 3y serves as the rear lamp unit, and the vehicle travels in the direction ii. Since the lamp unit 3y is the rear lamp unit and the lamp unit 3y is the front lamp unit, the front / rear direction of the vehicle itself is switched and displayed, so that a flexible traveling direction display according to the traveling direction of the vehicle can be performed. Moreover, since the lamp unit 3 of the same shape can be mounted in the front part and the rear part of the vehicle 2, there is also an advantage that the manufacturing cost can be suppressed.

次に、本発明の変形例２を、図６，７に基づいて説明する。この変形例では、図６に示すように、前照灯１１のＬＥＤ光源３１と同一部品上に、同一方向を向くイメージセンサ３２を搭載し、ＬＥＤ光源３１およびイメージセンサ３２からの信号に基づいて前照灯１１の向きを判定するＥＣＵ３３を備える。なお、ＬＥＤ光源３１およびイメージセンサ３２は、それぞれレンズホルダ３４または鏡筒３５により保護されている。
Next, a second modification of the present invention will be described with reference to FIGS. In this modified example, as shown in FIG. 6, an image sensor 32 facing the same direction is mounted on the same component as the LED light source 31 of the headlamp 11, and based on signals from the LED light source 31 and the image sensor 32. An ECU 33 that determines the direction of the headlamp 11 is provided. The LED light source 31 and the image sensor 32 are protected by a lens holder 34 or a lens barrel 35, respectively.
図７（ａ）に示すように、ＬＥＤ光源３１は投影パターンＡと、投影パターンＢを所定の周期Ｔで照射し、イメージセンサ３２は、投影パターンＢ照射中（Δｔ）に撮影を実施する。イメージセンサ３２の映像には、投影パターンＡ，Ｂの差分である消灯領域Ｄが映りこみ、暗部Ｄ’が形成される。ＥＣＵ３３では、暗部Ｄ’の先端位置Ｅと、ＬＥＤ光源との左右幅またはピクセル等の情報に基づいて演算を実施し、イメージセンサ３２の向きを判定する。このとき、イメージセンサ３２とＬＥＤ光源３１は同一部品上に搭載されているため、ＬＥＤ光源３１の向き、ひいては前照灯１１の向きを判定することができる。
As shown in FIG. 7A, the LED light source 31 irradiates the projection pattern A and the projection pattern B with a predetermined period T, and the image sensor 32 performs imaging during the projection pattern B irradiation (Δt). In the image of the image sensor 32, an unlit area D that is the difference between the projection patterns A and B is reflected, and a dark portion D 'is formed. In the ECU 33, the calculation is performed based on information such as the left and right width of the dark portion D ′ and the LED light source, the pixel width, and the like to determine the orientation of the image sensor 32. At this time, since the image sensor 32 and the LED light source 31 are mounted on the same component, the direction of the LED light source 31 and thus the direction of the headlamp 11 can be determined.
次に、本発明の変形例３を、図８に基づいて説明する。この変形例では、図８に示すように、前照灯１１の灯具ハウジング４３内において、エクステンション４２の一部にシボ４４による加工を施し、また、アウターレンズ４１の所定範囲にステップ４５を設け、シボ４４およびステップ４５による反射光を受光するカメラ５と、カメラ５の映像の明るさが所定の閾値を上回った場合に前照灯１１の積雪を検出する制御部としてのＥＣＵ（図示略）を備えている。
Next, Modification 3 of the present invention will be described with reference to FIG.

A camera 5 that receives the reflected light from the texture 44 and step 45, and an ECU (not shown) as a control unit that detects snow accumulation of the headlamp 11 when the brightness of the image of the camera 5 exceeds a predetermined threshold value. I have.
光源４６の照射範囲に雪が積もっている場合、出射光Ｌはアウターレンズ４１に積もった雪に反射されて灯具内部へ戻り（Ｌ１）、その後、シボ４４により反射され（Ｌ２）、最後にステップ４５により反射される（Ｌ３）。このとき、反射光Ｌ３はカメラ５の撮影範囲に含まれるため、カメラ５の映像は積雪が無かった場合に比較して明るくなる。カメラ５の映像信号を受信したＥＣＵは、映像の明るさが所定の閾値を上回った場合に、前照灯１１のアウターレンズ４１への積雪を検出できる。
When snow is accumulated in the irradiation range of the light source 46, the emitted light L is reflected by the snow accumulated on the outer lens 41 and returns to the inside of the lamp (L1), and then reflected by the embossing 44 (L2). (L3). At this time, since the reflected light L3 is included in the shooting range of the camera 5, the image of the camera 5 becomes brighter than when there is no snow. The ECU that has received the video signal of the camera 5 can detect snow accumulation on the outer lens 41 of the headlamp 11 when the brightness of the video exceeds a predetermined threshold.
なお、本発明は、上記実施例および変形例に限定されるものではなく、発明の趣旨を逸脱しない範囲で、各部の形状ならびに構成を適宜に変更して実施することも可能である。
The present invention is not limited to the above-described embodiments and modifications, and can be carried out by appropriately changing the shape and configuration of each part without departing from the spirit of the invention.
