Description
本発明は虚像を利用して意匠上の見栄えを良くした車両用照明装置に関する。 The present invention relates to a lighting device for a vehicle, which is improved in design appearance using a virtual image.
たとえば、フロントアクセサリランプ、テールランプ、テール／ストップランプ、フォグランプ等の車両用照明装置として、意匠上の見栄えを良くし、高級感を得るものがある。 For example, as lighting devices for vehicles such as front accessory lamps, tail lamps, tail / stop lamps, fog lamps, etc., there are ones that improve the design appearance and gain a sense of luxury.
この種の従来の車両用照明装置は、ミラーと、ミラー上に設けられた光源部と、ミラーに対向して設けられたハーフミラーとを備える。この場合、光源部から発生された光の一部はハーフミラーを透過して実像を形成し、他の一部はハーフミラーを反射した後にミラーで反射されてハーフミラーを透過することを繰り返して複数の虚像を形成する。従って、ハーフミラー上に奥行感がある複数の像を映し出すことにより意匠上の美感（見栄え）を生ずる（参照：特許文献１の図１〜図６）。 A conventional vehicle lighting device of this type includes a mirror, a light source unit provided on the mirror, and a half mirror provided to face the mirror. In this case, a part of the light generated from the light source part is transmitted through the half mirror to form a real image, and another part is repeatedly reflected by the mirror after being reflected by the half mirror and repeatedly transmitted through the half mirror. Form multiple virtual images. Therefore, by projecting a plurality of images with a sense of depth on the half mirror, an aesthetic sense (appearance) in design is produced (see: FIGS. 1 to 6 of Patent Document 1).
しかしながら、上述の従来の車両用照明装置においては、ハーフミラーに映し出される像の密度が小さく、従って、意匠上の見栄えが不充分であり、この結果、高級感が得られないという課題がある。 However, in the above-described conventional vehicle lighting device, the density of the image projected on the half mirror is small, and therefore the appearance on the design is insufficient, and as a result, there is a problem that a high-class feeling can not be obtained.
図５は比較例としての車両用照明装置を示す断面図である。以下に、図５を用いて従来の車両用照明装置の課題を説明する。 FIG. 5 is a cross-sectional view showing a vehicle lighting device as a comparative example. Below, the subject of the conventional illuminating device for vehicles is demonstrated using FIG.
図５において、１はハウジング、２はハウジング１の内面に設けられたミラー、３はハウジング１の上部に設けられた光源部、４はミラー２に対向したハーフミラーである。この場合、ミラー２の反射面はハーフミラー４の反射面に対向している。ハーフミラー４はアウタレンズ５の内面に金属蒸着され、前方透過および後方反射する。 In FIG. 5, 1 is a housing, 2 is a mirror provided on the inner surface of the housing 1, 3 is a light source unit provided on the top of the housing 1, and 4 is a half mirror facing the mirror 2. In this case, the reflection surface of the mirror 2 faces the reflection surface of the half mirror 4. The half mirror 4 is metal-deposited on the inner surface of the outer lens 5 and transmits and reflects back and forth.
光源部３は遮光性のケース３１、一端に発光ダイオード素子が設けられたケース３１内のポリカーボネート樹脂等よりなる導光棒３２、及びケース３１のハーフミラー４側に設けられた乳白色レンズ３３よりなる。この場合、導光棒３２からの光は乳白色レンズ３３によってハーフミラー４の反射面に対してやや斜め下方へ出射するようにされている。 The light source unit 3 includes a light shielding case 31, a light guide rod 32 made of polycarbonate resin or the like in the case 31 provided with a light emitting diode element at one end, and a milky white lens 33 provided on the half mirror 4 side of the case 31. . In this case, the light from the light guide rod 32 is emitted slightly obliquely downward to the reflection surface of the half mirror 4 by the milky white lens 33.
導光棒３２からの光は乳白色レンズ３３を介して出射してハーフミラー４を透過し、その透過光Ｌ１は光源部３の導光棒３２の図６に示す実像Ｉ１を形成する。さらに、ハーフミラー４を反射した後にミラー２で反射してハーフミラー４を透過し、その透過光Ｌ２、Ｌ３、Ｌ４、…は光源部３の導光棒３２の図６に示す虚像Ｉ２、Ｉ３，Ｉ４、…を形成する。この場合、光Ｌ１、Ｌ２、Ｌ３、Ｌ４、…の光路長はこの順序で次第に長くなるので、光Ｌ１、Ｌ２、Ｌ３、Ｌ４、…の図６の像Ｉ１、Ｉ２、Ｉ３，Ｉ４、…は導光棒３２の相似形で次第に小さくなり、奥行感が得られる。この結果、図６に示すように、ハーフミラー４上に導光棒３２と相似形の像Ｉ１、Ｉ２、Ｉ３，Ｉ４、…が映し出され、これにより、意匠上の見栄えを向上させることができる。 The light from the light guide rod 32 is emitted through the milky white lens 33 and passes through the half mirror 4, and the transmitted light L 1 forms a real image I 1 shown in FIG. 6 of the light guide rod 32 of the light source unit 3. Further, after reflecting the half mirror 4, the light is reflected by the mirror 2 and transmitted through the half mirror 4. The transmitted lights L2, L3, L4,... Are virtual images I2 and I3 shown in FIG. , I4,... In this case, since the optical path lengths of the lights L1, L2, L3, L4, ... gradually become longer in this order, the images I1, I2, I3, I4, ... of Fig. 6 of the lights L1, L2, L3, L4, ... are The similar shape of the light guide rod 32 gradually becomes smaller, and a sense of depth can be obtained. As a result, as shown in FIG. 6, the images I1, I2, I3, I4,... Of similar shapes to the light guide rod 32 are displayed on the half mirror 4, whereby the appearance on the design can be improved. .
しかしながら、図５に示す比較例としての車両用照明装置においては、図６に示すように、像Ｉ１、Ｉ２，Ｉ３、Ｉ４、…の密度が小さいので、意匠上の見栄えが不充分であり、この結果、高級感が得られないという課題がある。 However, in the vehicle lighting device as the comparative example shown in FIG. 5, since the density of the images I1, I2, I3, I4,... Is low as shown in FIG. As a result, there is a problem that a sense of luxury can not be obtained.
上述の課題を解決するために、本発明に係る車両用照明装置は、ハウジングと、ハウジングの内面に設けられたミラーと、ハウジング内の上部又は下部に設けられた光源部と、ハウジングのミラーに対向して設けられたハーフミラーとを具備し、光源部は、遮光性のケースと、ケース内に設けられた発光素子又は導光棒と、ケースに設けられ、発光素子又は導光棒からの第１の光をハーフミラーの反射面へ斜めに出射するための第１のレンズと、ケースに設けられ、発光素子又は導光棒からの第２の光をミラーの反射面へ斜めに出射するための第２のレンズとを具備するものである。 In order to solve the above-described problems, a lighting device for a vehicle according to the present invention comprises a housing, a mirror provided on the inner surface of the housing, a light source unit provided on the upper or lower portion in the housing, and a mirror of the housing. The light source unit includes a light shielding case, a light emitting element or a light guide bar provided in the case, and a light source unit provided on the case from the light emitting element or the light guide bar.
