Abstract

<P>PROBLEM TO BE SOLVED: To provide an indicating lamp device for vehicle that can be visually recognized as a display lamp, has small power consumption, and is miniaturized. <P>SOLUTION: In the indicating lamp device for vehicle, a translucent material 12 whose sections are in a biconvex lens is arranged at a front position that faces a light-emitting diode 4 that becomes a light source. As a result, light from the light-emitting diode is radiated to the outside through the translucent material, but is condensed by the biconvex lens, thus improving visibility and reducing power consumption. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、概し、自動車の補助灯として用いられている車高灯、マーカーランプ或いは車幅灯等の自動車用表示灯装置に関するものである。   The present invention generally relates to a vehicle indicator lamp device such as a vehicle height lamp, a marker lamp, or a vehicle width lamp that is used as an auxiliary lamp of an automobile.

車幅灯等の表示灯の光源として発光ダイオードが用いられているが、発光ダイオードは、所謂電球と較べ発光量が少く、それを補うため、該ダイオードを多数用いるようにしたり、或いは、文献１で示すように発光ダイオードの収納室を構成させて、該ダイオードと相対する前方に配置した透孔材（板）の表面を凹凸状と成し、その凹凸によって発光ダイオードを光源とする光を拡散させ視認し易くするようにしている構造のものがある。   A light emitting diode is used as a light source of a display lamp such as a vehicle width lamp. However, the light emitting diode has a smaller light emission amount than a so-called light bulb, and in order to compensate for this, a large number of the diodes are used. As shown in Fig. 2, the storage chamber of the light emitting diode is configured, and the surface of the through-hole material (plate) disposed in front of the diode is made uneven, and the light using the light emitting diode as a light source is diffused by the unevenness. There is a structure that makes it easy to visually recognize.

前記従来例は、発光ダイオードからの光を所謂乱反射させて発光量の少さを補うものであるが、最終的には乱反射の光によって明るさを利用するため近傍での当該光を利用した視認用として好都合であるが、車高幅とか車幅とか比較的遠方から当該光を利用しての視認用としての表示灯には必ずしも適切なものとはいえない。   In the conventional example, the light from the light emitting diode is so-called diffusely reflected to compensate for a small amount of light emission. Ultimately, since the brightness is used by the diffusely reflected light, the light is visually recognized in the vicinity. Although it is convenient for use, it is not necessarily suitable for an indicator lamp for visual recognition using the light from a relatively long distance such as a vehicle height or a vehicle width.

本発明は、発光ダイオードを光源とし、比較的遠方から視認でき、車高灯や車幅等に用いるに好適な自動車や表示灯装置を提供すべく創案したものである。   The present invention has been devised to provide an automobile and an indicator lamp device that use a light emitting diode as a light source and can be viewed from a relatively long distance, and are suitable for use in a vehicle height lamp, a vehicle width, and the like.

光源となる発光ダイオードと相対する前方位置に、断面両凸レンズ状の透光材を配設した構成としたものである。   In this configuration, a translucent material having a biconvex lens shape in cross section is disposed at a front position facing a light emitting diode as a light source.

本発明によれば、発光ダイオードからの光が透孔材を通じて外部に放出され、しかも、該光は、透孔材の断面両凸レンズ状の形状によって集光されるから視認し易く、消費電力が少く、小形化した表示灯装置を提供できる。   According to the present invention, the light from the light emitting diode is emitted to the outside through the hole material, and the light is collected by the shape of the biconvex lens in the cross section of the hole material so that it is easy to see and consumes less power. A small and compact indicator lamp device can be provided.

図面は本発明に係る車高灯などの自動車用表示灯装置の一実施例を示し、図１は縦断面図、図２は図１の平面図である。   The drawings show an embodiment of an indicator light device for an automobile such as a vehicle lamp according to the present invention, FIG. 1 is a longitudinal sectional view, and FIG. 2 is a plan view of FIG.

図中、１はベースで、ベース１は、ベースパッキン２を介して図示省略した車体に止着ねじ３によって取付けたもので、このベース１には等間隔を存して発光ダイオード４，…を並設したプリント基板５を収設し、該プリント基板５を電源コード６を介して電源に接続して車体の適所に装置したスイッチ装置によって前記発光ダイオード４，…の点滅操作を行うようにしてある。   In the figure, reference numeral 1 denotes a base. The base 1 is attached to a vehicle body (not shown) via a base packing 2 by means of a fastening screw 3, and the light emitting diodes 4,. The printed circuit boards 5 arranged side by side are accommodated, and the printed circuit board 5 is connected to a power source via a power cord 6 so that the light emitting diodes 4,... is there.

このプリント基板５の表面側には、列設した透孔７，…に前記発光ダイオード４を貫通係合させて、しかも、各発光ダイオード４毎に該発光ダイオードを中心とした表面凹面状の反射面８，…を備えた反射板９を重ね合わせ、該反射板９等を套装する套装枠１０と共に締付けねじ１１で前記ベース１に止着してある。   On the surface side of the printed circuit board 5, the light emitting diodes 4 are through-engaged with the through-holes 7,... Arranged in a row, and each light emitting diode 4 has a surface-concave reflection centered on the light emitting diode. A reflecting plate 9 having surfaces 8,... Is overlapped, and is fastened to the base 1 with a tightening screw 11 together with a cover frame 10 for covering the reflecting plate 9 and the like.

套装枠１０は、前記ベース１に設けた、前記プリント基板５を取り囲む周壁部１ａを内側に係合して前記の通りベース１に止着したもので、ベース１の正面輪郭形と相似する正面輪郭形の正面壁板１０ａの周端に側壁板１０ｂを設け、側壁板１０ｂの内側にベース周壁部１ａを配してベース１に前記の通り止着し、正面壁板１０ａの、前記発光ダイオード４と対応し、しかも、内側面１２ａを発光ダイオード４および該ダイオード４を取り囲む凹面状の前記反射面８と対向させて位置させ、内外面１２ａ，１２ｂそれぞれが円弧状凸面形状の、全体として断面凸レンズ状の透孔材１２，…を設けたものである。   The dressing frame 10 is formed by engaging the peripheral wall 1a surrounding the printed circuit board 5 provided on the base 1 on the inside, and is fixed to the base 1 as described above. A side wall plate 10b is provided at the peripheral end of the contoured front wall plate 10a, a base peripheral wall portion 1a is disposed inside the side wall plate 10b, and is fixed to the base 1 as described above. 4, and the inner side surface 12 a is positioned to face the light emitting diode 4 and the concave reflecting surface 8 surrounding the diode 4, and the inner and outer surfaces 12 a and 12 b are arcuate convex surfaces as a whole. Convex lens-shaped through-hole members 12, ... are provided.

なお、実施例は４本の発光ダイオード４，４，４，４を用いた車高灯に本発明を適用してあるが、本発明は車幅灯その他の表示灯に適用でき、単一な発光ダイオード４を用いる場合にも適用できる。   In the embodiment, the present invention is applied to a vehicle height light using four light emitting diodes 4, 4, 4 and 4. However, the present invention can be applied to a vehicle width light and other indicator lights. The present invention can also be applied when the light emitting diode 4 is used.

また、反射板９に備え、中心部に発光ダイオード４を配した凹面状の反射面８は発光ダイオード４の光を受け、これを透孔材１２方向に反射せしめて、その反射分が余分に透孔材１２に集光され、視認効果を増大させることができる。   Further, the concave reflecting surface 8 provided in the reflecting plate 9 and having the light emitting diode 4 disposed at the center receives the light of the light emitting diode 4 and reflects it in the direction of the hole 12 so that the reflection is excessive. It is condensed on the through-hole material 12, and the visual recognition effect can be increased.
