しかしながら、前述した特許文献1に記載の車両用照明装置では、面状に発光させるには、光源であるLEDからの光を広げる導光体を別途用いる必要があり、部品点数の増加、コストアップ、組み立て工数の増加等をまねくという問題がある。  However, in the vehicle lighting device described in Patent Document 1 described above, in order to emit light in a planar shape, it is necessary to separately use a light guide that spreads light from the LED that is the light source, which increases the number of components and increases the cost. There is a problem of increasing the number of assembly steps.

そこで、本発明は、上記問題点を解決するために、部品点数の増加やコストの増加を抑えて、車両用内装材を面状に発光させることができる車両用照明装置を提供することにある。  SUMMARY OF THE INVENTION In order to solve the above problems, the present invention is to provide a vehicular illumination device capable of emitting a vehicular interior material in a planar shape while suppressing an increase in the number of parts and an increase in cost. .

上記課題を解決するために、本発明に係る車両用照明装置は、車両用内装材を発光させる車両用照明装置であって、発光させる前記車両用内装材を透光性の樹脂で形成し、前記樹脂の少なくとも一端面に光源を対向配置したものである。  In order to solve the above problems, a vehicle lighting device according to the present invention is a vehicle lighting device that emits light from a vehicle interior material, and the vehicle interior material that emits light is formed of a translucent resin. A light source is disposed opposite to at least one end surface of the resin.

この構成によれば、車両用内装材を透明あるいは半透明の透光性を有する樹脂で形成し、樹脂の少なくとも一端面に対向して光源を配置したので、光源からの光は、車両用内装材である樹脂を導光体として光が伝達され、面状に発光する。
これにより、従来のように導光体を別個に設ける必要がないため、部品点数の増加やコストの増加を抑えて、車両用内装材を面状に発光させることができる。また、既存の部品を用いるので、組み立て工数が増加しない。
According to this configuration, the vehicle interior material is formed of a transparent or translucent resin having translucency, and the light source is disposed so as to face at least one end surface of the resin. Light is transmitted using a resin, which is a material, as a light guide, and light is emitted in a planar shape.
Thereby, since it is not necessary to provide a light guide separately as in the prior art, it is possible to suppress the increase in the number of parts and the cost and to cause the vehicle interior material to emit light in a planar shape. In addition, since existing parts are used, the number of assembly steps does not increase.

上記構成において、前記樹脂の表面であって発光させない部位には遮光の表面処理を行うものである。  In the above configuration, the surface of the resin that does not emit light is subjected to a light-shielding surface treatment.

この構成によれば、樹脂の表面に、任意の模様等を付して遮光することにより、発光部分の形状等を規制することができる。  According to this configuration, it is possible to regulate the shape or the like of the light emitting portion by providing an arbitrary pattern or the like on the surface of the resin to shield it from light.

上記構成において、前記表面処理が、塗装、印刷、メッキであるものである。  In the above configuration, the surface treatment is painting, printing, or plating.

この構成によれば、樹脂の表面に遮光のために施す表面処理として、塗装、印刷、メッキ等を用いることができる。
なお、塗装、印刷、メッキの厚さを調整することにより、全体を薄くぼんやりと発光させることもできる。
According to this configuration, coating, printing, plating, or the like can be used as the surface treatment applied to the resin surface for light shielding.
By adjusting the thickness of painting, printing, and plating, the whole can be thinly and lightly emitted.

上記構成において、前記発光させない部位が模様であるものである。  The said structure WHEREIN: The site | part which is not made to light-emit is a pattern.

この構成によれば、樹脂の表面に、表面処理を施して模様を形成することができるので、光源を発光させることにより、模様を浮き上がらせて表示することができる。  According to this configuration, the surface of the resin can be subjected to a surface treatment to form a pattern, so that the pattern can be lifted and displayed by causing the light source to emit light.

本発明によれば、車両用内装材を透明あるいは半透明の透光性を有する樹脂で形成し、樹脂の少なくとも一端面に対向して光源を配置したので、光源からの光は、車両用内装材である樹脂を導光体として光が伝達され、面状に発光する。これにより、従来のように導光体を別個に設ける必要がないため、部品点数の増加やコストの増加を抑えて、車両用内装材を面状に発光させることができる。また、既存の部品を用いるので、組み立て工数が増加しないという効果がある。  According to the present invention, the vehicle interior material is formed of a transparent or translucent resin having translucency, and the light source is disposed opposite to at least one end surface of the resin. Light is transmitted using a resin, which is a material, as a light guide, and light is emitted in a planar shape. Thereby, since it is not necessary to provide a light guide separately as in the prior art, it is possible to suppress the increase in the number of parts and the cost and to cause the vehicle interior material to emit light in a planar shape. In addition, since existing parts are used, there is an effect that the number of assembling steps does not increase.

以下、添付図面を参照して、本発明を実施するための形態(以下、実施形態)について詳細に説明する。なお、実施形態の説明の全体を通して同じ要素には同じ番号を付している。  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the accompanying drawings. Note that the same number is assigned to the same element throughout the description of the embodiment.

図1に示すように、本発明にかかる車両用照明装置10は、例えば、ドアトリム20に適用することができる。
ドアトリム20は、ドアベース21の上に、車室内の意匠性を考慮した樹脂製の表皮材22が貼り付けられている。この表皮材22は、透光性を有しない。
ドアベース21には、高さ方向中央部に開口23が設けられており、開口23の上下に垂直に延びる鍔部211、212が設けられている。開口23は発光させる車両用内装材であるフィニッシャ(加飾部品)24により覆われる。フィニッシャ24は、透明あるいは半透明の透光性を有する樹脂で形成されており、上下の鍔部211,212に当接して取り付けられる。
As shown in FIG. 1, thevehicle lighting device 10 according to the present invention can be applied to, for example, adoor trim 20.
In thedoor trim 20, aresin skin material 22 is applied on thedoor base 21 in consideration of design in the vehicle interior. Thisskin material 22 does not have translucency.
Thedoor base 21 is provided with an opening 23 in the center in the height direction, andflanges 211 and 212 extending vertically above and below the opening 23. The opening 23 is covered with a finisher (decorative component) 24 that is a vehicle interior material that emits light. Thefinisher 24 is formed of a transparent or translucent resin having translucency, and is attached in contact with the upper andlower flange portions 211 and 212.

図2(A)および(B)に示すように、フィニッシャ24の一端面である下端面241に対向して、光源であるLED25が設けられている。LED25は基板26に複数個実装されており、下端面241の長手方向に沿って対向配置されている。
なお、ここでは、フィニッシャ24の下端面241に対向してLED25および基板26を設けたが、このほか、フィニッシャ24の上端面や側端面に対向して設けることも可能である。あるいは、上下端面や側端面を組み合わせて設けることも可能である。
As shown in FIGS. 2A and 2B, anLED 25 that is a light source is provided so as to face alower end surface 241 that is one end surface of thefinisher 24. A plurality ofLEDs 25 are mounted on thesubstrate 26, and are arranged to face each other along the longitudinal direction of thelower end surface 241.
Here, theLED 25 and thesubstrate 26 are provided facing thelower end surface 241 of thefinisher 24, but it is also possible to provide theLED 25 and the side end surface facing thefinisher 24. Alternatively, it is possible to provide a combination of upper and lower end surfaces and side end surfaces.

フィニッシャ24の発光させない部位には、表面に遮光の表面処理を行う。遮光の表面処理としては、例えば、図2(B)に示すように、フィニッシャ24の表面に、遮光性のある塗装27、印刷、メッキ等を施す。ここでは、フィニッシャ24において遮光の表面処理(塗装)を行っていない下部242から光LBが漏れて下方を照明する。
また、フィニッシャ24に、遮光の表面処理によって模様や文字等を形成することにより、文字や、模様を浮き上がらせることができる。
The surface of thefinisher 24 that does not emit light is subjected to a light-shielding surface treatment. As the surface treatment for light shielding, for example, as shown in FIG. 2B, the surface of thefinisher 24 is subjected tolight shielding coating 27, printing, plating, or the like. Here, the light LB leaks from the lower part 242 where the surface treatment (painting) of light shielding is not performed in thefinisher 24 and illuminates the lower part.
Further, by forming a pattern, a character, or the like on thefinisher 24 by a light-shielding surface treatment, the character or the pattern can be raised.

以上説明したことから明らかとなるように、本発明にかかる車両用照明装置10によれば、フィニッシャ24を透明あるいは半透明の透光性を有する樹脂で形成し、樹脂の下端面241に対向してLED25を配置したので、LED25からの光LBは、フィニッシャ24である樹脂を導光体として光が伝達され、面状に発光する。
これにより、従来のように導光体を別個に設ける必要がないため、部品点数の増加やコストの増加を抑えて、フィニッシャ24を面状に発光させることができる。また、既存の部品を用いるので、組み立て工数が増加しない。
As will be apparent from the above description, according to thevehicle lighting device 10 of the present invention, thefinisher 24 is formed of a transparent or translucent resin having translucency and is opposed to thelower end surface 241 of the resin. Since theLED 25 is disposed, the light LB from theLED 25 is transmitted through the resin as thefinisher 24 as a light guide, and is emitted in a planar shape.
Thereby, since it is not necessary to provide a light guide separately as in the prior art, thefinisher 24 can emit light in a planar shape while suppressing an increase in the number of parts and an increase in cost. In addition, since existing parts are used, the number of assembly steps does not increase.

また、フィニッシャ24の表面に、任意の模様等を付して遮光することにより、発光部分の形状等を規制することができる。  Further, the shape or the like of the light emitting portion can be regulated by providing an arbitrary pattern or the like on the surface of thefinisher 24 to shield the light.

また、フィニッシャ24の表面に遮光のために施す表面処理として、塗装、印刷、メッキ等を用いることができる。
なお、塗装、印刷、メッキの厚さを調整することにより、全体を薄くぼんやりと発光させることもできる。
Further, as the surface treatment applied to the surface of thefinisher 24 for light shielding, painting, printing, plating, or the like can be used.
By adjusting the thickness of painting, printing, and plating, the whole can be thinly and lightly emitted.

さらに、フィニッシャ24の表面に、表面処理を施して模様を形成することができるので、LED25を発光させることにより、模様を浮き上がらせて表示することができる。  Furthermore, since the surface of thefinisher 24 can be subjected to surface treatment to form a pattern, the pattern can be lifted and displayed by causing theLED 25 to emit light.

以上、実施形態を用いて本発明を説明したが、本発明の技術的範囲は上記実施形態に記載の範囲には限定されないことは言うまでもない。上記実施形態に、多様な変更または改良を加えることが可能であることが当業者に明らかである。またその様な変更または改良を加えた形態も本発明の技術的範囲に含まれ得ることが、特許請求の範囲の記載から明らかである。
例えば、前述した実施形態においては、ドアトリム20のフィニッシャ24に本発明に係る車両用照明装置10を設けた場合を例示したが、これに限るものではない。その他の部位、例えば、パワーウインドウスイッチのフィニッシャや、ドアグリップキャップ等にも適用可能である。
As mentioned above, although this invention was demonstrated using embodiment, it cannot be overemphasized that the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiments. Further, it is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
For example, in the above-described embodiment, the case where thevehicle lighting device 10 according to the present invention is provided in thefinisher 24 of the door trim 20 is illustrated, but the present invention is not limited thereto. The present invention can also be applied to other parts, for example, a finisher for a power window switch, a door grip cap, and the like.

また、前述した実施形態においては、遮光の表面処理として、フィニッシャ24の表面に塗装やメッキを施す場合を例示したが、図3に示すように、透光性の樹脂(下部242)と遮光性の樹脂28を用いてフィニッシャ24Bを一体成型する車両用照明装置10Bも可能である。  In the above-described embodiment, the case where the surface of thefinisher 24 is coated or plated is exemplified as the surface treatment for light shielding. However, as shown in FIG. Avehicle lighting device 10B in which thefinisher 24B is integrally molded using theresin 28 is also possible.
