　本発明は、車両の室内照明などの用途で利用可能な光源ユニット及び照明装置に関する。 The present invention relates to a light source unit and an illuminating device that can be used for applications such as vehicle interior lighting.
　自動車等の車両には、一般に、車内を照明する車内照明装置が設けられる。例えば、車内照明装置として、車内の装飾を目的としてコンソールボックス、天井またはドア等に設けられ、種々の色で発光するイルミネーション機器を備えた装置が挙げられる（例えば、特許文献１及び特許文献２を参照）。 Vehicles such as automobiles are generally provided with an interior lighting device that illuminates the interior of the vehicle.

　ところで、車内の装飾を目的とした車内照明装置において、その装飾効果を高めるため、光源を構成する複数色のＬＥＤ等を選択的に発光させて発色度合いを変化させる点灯（いわゆるグラデーション）が行われる場合がある。この場合、目標とする発色度合いに応じて光源内のＬＥＤ等をそれぞれ制御することになるため、制御装置における部品数の増大及び制御の複雑化を招き、車内照明装置の製造コストが増大する虞がある。 By the way, in an in-vehicle lighting device for the purpose of interior decoration, lighting (so-called gradation) is performed to selectively emit light of a plurality of LEDs constituting a light source to change the degree of color development in order to enhance the decoration effect. There is a case. In this case, since the LEDs and the like in the light source are controlled according to the target color development degree, the number of parts in the control device is increased and the control is complicated, which may increase the manufacturing cost of the interior lighting device.

A lighting device may be designed. However, in this case, since a large number of LEDs are arranged, the number of components of the light source is increased, and the circuit configuration of the light source for controlling these LEDs is also complicated. Therefore, like the above, the manufacturing cost of the in-vehicle lighting device may increase.
　本発明は、上述した事情に鑑みてなされたものであり、その目的は、細長い範囲を照明する場合であっても部品数を低減して低コスト化が可能な光源ユニット及び照明装置、を提供することにある。 The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a light source unit and an illuminating device capable of reducing the number of parts and reducing the cost even when illuminating a long and narrow area.

　本発明の光源ユニット及び照明装置に関する具体的な実施形態について、各図を参照しながら以下に説明する。 Specific embodiments relating to the light source unit and the illumination device of the present invention will be described below with reference to the drawings.
＜光源ユニットの説明＞
　図１（ａ）は本発明の実施形態における指針ユニット１５の外観を示す斜視図、図１（ｂ）は遮光ケース１９を取り去った状態の指針ユニット１５を示す斜視図、図１（ｃ）は指針ユニット１５の構成部品を並べて示す平面図である。この指針ユニット１５は、イルミネーションや表示に利用可能な本発明の実施形態における光源ユニットの一例である。 <Description of light source unit>
1A is a perspective view showing the appearance of the pointer unit 15 in the embodiment of the present invention, FIG. 1B is a perspective view showing the pointer unit 15 with the light shielding case 19 removed, and FIG. FIG. 3 is a plan view showing the components of the pointer unit 15 side by side. The pointer unit 15 is an example of a light source unit in the embodiment of the present invention that can be used for illumination and display.
　図１（ｃ）に示すように、この指針ユニット１５は光源１６を有するベース部材１７と、指針状導光体１８と、遮光ケース１９と、から構成されている。光源１６は、例えばＬＥＤ（Ｌｉｇｈｔ　Ｅｍｉｔｔｉｎｇ　Ｄｉｏｄｅ）のような点光源であり、ベース部材１７の上方に向けて光を出射することができる。 As shown in FIG. 1C, the pointer unit 15 is composed of a base member 17 having a light source 16, a pointer-shaped light guide 18, and a light shielding case 19. The light source 16 is a point light source such as an LED (Light Emitting Diode), and can emit light toward the upper side of the base member 17.
　指針状導光体１８は、透明な樹脂などの材料で構成される導光体であり、全体として棒状の形状（換言すると、細長い形状、及び、針状の形状など）を有するように形成されている。この指針状導光体１８は、光源１６の光出射面と同等の寸法に形成された細い光導入部１８ａを下方に有し、上方の発光面１８ｂは細長く直線状に延びている。 The pointer-shaped light guide 18 is a light guide made of a material such as a transparent resin, and is formed to have a rod-like shape (in other words, an elongated shape, a needle-like shape, etc.) as a whole. ing. The pointer-shaped light guide 18 has a thin light introduction portion 18a formed at the same size as the light emitting surface of the light source 16 on the lower side, and the upper light emitting surface 18b is elongated and extends linearly.
　指針状導光体１８は、光導入部１８ａの下端が光源１６の光出射面と隣接する状態で、かつ図１（ｂ）に示すように起立した状態でベース部材１７上に配置される。また、指針状導光体１８はベース部材１７に形成した複数の導光体支持部１７ａ、１７ｂ及び１７ｃにより支持され、強固にベース部材１７に固定される。 The pointer-shaped light guide 18 is disposed on the base member 17 in a state where the lower end of the light introducing portion 18a is adjacent to the light emitting surface of the light source 16 and is erected as shown in FIG. The pointer-shaped light guide 18 is supported by a plurality of light guide support portions 17 a, 17 b and 17 c formed on the base member 17, and is firmly fixed to the base member 17.
　指針状導光体１８は、光源１６が出射した光を光導入部１８ａから導入し、内部における拡散や反射により細長い発光面１８ｂの全体にほぼ均等に光を導く。したがって、光源１６が発光すると、指針状導光体１８の発光面１８ｂ全体が発光する。 The pointer-shaped light guide 18 introduces the light emitted from the light source 16 from the light introducing portion 18a, and guides the light almost uniformly to the entire elongated light emitting surface 18b by diffusion and reflection inside. Therefore, when the light source 16 emits light, the entire light emitting surface 18b of the pointer-shaped light guide 18 emits light.
　遮光ケース１９は、ベース部材１７上に配置され、指針状導光体１８のほぼ全体を周囲から覆うことができる形状に形成されている。遮光ケース１９は遮光性の材料で構成されているが、指針状導光体１８の発光面１８ｂと対向する箇所に線状またはスリット状の開口部１９ａが形成されている。なお、開口部１９ａは、透明な材料で覆われていても良い。 The light shielding case 19 is disposed on the base member 17 and is formed in a shape that can cover almost the entire pointer-shaped light guide 18 from the periphery. Although the light shielding case 19 is made of a light shielding material, a linear or slit-shaped opening 19 a is formed at a location facing the light emitting surface 18 b of the pointer light guide 18. Note that the opening 19a may be covered with a transparent material.
　したがって、ベース部材１７上の光源１６が発光すると、指針状導光体１８で導かれた光が、発光面１８ｂから開口部１９ａを経由して指針ユニット１５の外側に出射される。つまり、ユーザは開口部１９ａの部位のみで発光を視認できる。遮光ケース１９を設けることにより、必要な部位以外に光が漏れることがなくなり、所望の細長い形状で発光する光源ユニットを構成できる。 Therefore, when the light source 16 on the base member 17 emits light, the light guided by the pointer light guide 18 is emitted from the light emitting surface 18b to the outside of the pointer unit 15 through the opening 19a. That is, the user can visually recognize light emission only at the site of the opening 19a. By providing the light shielding case 19, light can be prevented from leaking to areas other than necessary, and a light source unit that emits light in a desired elongated shape can be configured.
＜照明装置の基本構成＞
　図２（ａ）および図２（ｂ）は図１の指針ユニット１５の構造を採用した発光器具２５の基本的な構成を表し、図２（ａ）は平面図、図２（ｂ）は図２（ａ）におけるＡ－Ａ’断面を示す縦断面図である。 <Basic configuration of lighting device>
2 (a) and 2 (b) show a basic configuration of the light emitting device 25 adopting the structure of the pointer unit 15 of FIG. 1, FIG. 2 (a) is a plan view, and FIG. 2 (b) is a diagram. It is a longitudinal cross-sectional view which shows the AA 'cross section in 2 (a).
　図２（ａ）および図２（ｂ）に示した発光器具２５は、光源１６、指針状導光体１８及び遮光部付意匠部品２６により構成されている。遮光部付意匠部品２６は、薄板状に形成され、細長い形状に形成された開口部２６ａを有し、開口部２６ａ以外の部位が遮光性の材料で構成されている。また、遮光部付意匠部品２６は指針状導光体１８の発光面１８ｂと密着または接近した状態で配置されている。 2 (a) and 2 (b) includes a light source 16, a pointer-shaped light guide 18, and a design part 26 with a light shielding portion. The design part 26 with a light shielding part is formed in a thin plate shape, has an opening 26a formed in an elongated shape, and a part other than the opening 26a is made of a light shielding material. In addition, the design part 26 with the light-shielding part is arranged in close contact with or close to the light emitting surface 18b of the pointer-shaped light guide 18.
　したがって、図２（ａ）および図２（ｂ）に示した発光器具２５を利用する場合、光源１６が発光すると、図２（ａ）に示した発光器具２５の開口部２６ａの部位だけが細長い形状で発光しているようにユーザに視認される。この場合、必要な範囲だけを効率的に発光させることができる。また、複数の光源を用いなくても細長い形状の発光を実現できる。 Accordingly, when the light emitting device 25 shown in FIGS. 2A and 2B is used, when the light source 16 emits light, only the portion of the opening 26a of the light emitting device 25 shown in FIG. 2A is elongated. It is visually recognized by the user as if it is emitting light in a shape. In this case, only the necessary range can be efficiently emitted. In addition, a long and narrow light emission can be realized without using a plurality of light sources.
　図３（ａ）および図３（ｂ）は図２の発光器具の変形例を表し、図３（ａ）は平面図、図３（ｂ）は図３（ａ）におけるＢ－Ｂ’断面を示す縦断面図である。図３（ａ）および図３（ｂ）に示した発光器具２５Ｂは、光源１６と、指針状導光体１８と、意匠部品２７とを備えている。なお、発光器具２５Ｂには遮光部が存在しないが、必要に応じて付加することもできる。 3 (a) and 3 (b) show a modification of the light emitting device of FIG. 2, FIG. 3 (a) is a plan view, and FIG. 3 (b) is a cross-sectional view taken along line BB ′ in FIG. 3 (a). It is a longitudinal cross-sectional view shown. The light emitting device 25B shown in FIGS. 3A and 3B includes a light source 16, a pointer-shaped light guide 18, and a design component 27. In addition, although the light-shielding part does not exist in the light emission instrument 25B, it can also be added as needed.
　図３（ａ）および図３（ｂ）に示した発光器具２５Ｂにおいて、意匠部品２７は指針状導光体１８の発光面１８ｂから所定距離離れた位置に配置されている。意匠部品２７は薄板状に形成され、その全体が光を透過する材料で構成されている。光源１６が発光すると、発光面１８ｂは線状に発光するが、発光面１８ｂと意匠部品２７との距離に応じ、発光形状が変化する。すなわち、図３（ａ）に示すように、意匠部品２７上の発光部２７ａは、楕円形状になり、かつグラデーションのある発光になる。 3A and 3B, the design component 27 is disposed at a position away from the light emitting surface 18b of the pointer light guide 18 by a predetermined distance. The design component 27 is formed in a thin plate shape, and the whole is made of a material that transmits light. When the light source 16 emits light, the light emitting surface 18b emits light linearly, but the light emitting shape changes according to the distance between the light emitting surface 18b and the design component 27. That is, as shown to Fig.3 (a), the light emission part 27a on the design component 27 becomes elliptical light emission with gradation.
　したがって、発光器具２５Ｂのように、発光面１８ｂと意匠部品２７とを離間させて配置することにより、光源１６の数を増やさなくても、比較的広い範囲を発光させることができ、しかもグラデーションにより演出効果に優れたイルミネーションを実現することができる。 Therefore, by disposing the light emitting surface 18b and the design component 27 apart from each other as in the light emitting device 25B, a relatively wide range can be emitted without increasing the number of the light sources 16, and the gradation can be increased. Illumination with excellent production effects can be realized.
＜照明装置の具体的な構成例＞
　図１の指針ユニット及びその変形例を採用した照明オーナメント（装飾部品）筐体の構成例を図４に示す。また、図４におけるＣ－Ｃ’線に示す断面位置における装置内部の概略構成を図５に示し、図４におけるＤ－Ｄ’線に示す断面位置における装置内部の概略構成を図６に示す。なお、図５及び図６は、厳密な断面図とは異なる概念図である。 <Specific configuration example of lighting device>
FIG. 4 shows a configuration example of a lighting ornament (decorative part) housing employing the pointer unit of FIG. 1 and its modification. FIG. 5 shows a schematic configuration inside the apparatus at the cross-sectional position indicated by the line CC ′ in FIG. 4, and FIG. 6 shows a schematic configuration inside the apparatus at the cross-sectional position indicated by the line DD ′ in FIG. 5 and 6 are conceptual diagrams different from the strict sectional views.
　図４に示した照明オーナメント筐体２８は、第１照明部２８ａおよび第２照明部２８ｂを備えている。第１照明部２８ａには、３個の発光器具３７Ａ、３７Ｂ及び３７Ｃが含まれている。また、第２照明部２８ｂには６個の発光器具３８Ａ、３８Ｂ、３８Ｃ、３８Ｄ、３８Ｅ及び３８Ｆが含まれている。 The illumination ornament housing 28 shown in FIG. 4 includes a first illumination unit 28a and a second illumination unit 28b. The first lighting unit 28a includes three light emitting devices 37A, 37B, and 37C. The second illumination unit 28b includes six light emitting devices 38A, 38B, 38C, 38D, 38E, and 38F.
　第１照明部２８ａの発光器具３７Ａは、図５に示すように、赤色ＬＥＤユニット５６Ａ、遮光ケース５７Ａおよび意匠部品５８を有している。遮光ケース５７Ａには図示しない開口部が形成されている。また、遮光ケース５７Ａは意匠部品５８の意匠面５８ａ（具体的には、この意匠部位に対応する意匠部品５８の内壁面）から少し離れた位置に配置してあり、意匠部品５８と一体に構成してある。なお、図５では、発光器具３７Ａと発光器具３７Ｂとが単一の意匠部品５８を共有するように図示されている。しかし、図５はあくまで発光器具３７Ａ及び発光器具３７Ｂの内部構造を概念的に示す図であり、実際には、図４に示すように発光器具３７Ａ及び発光器具３７Ｂは、互いに独立した部材であり、互いに独立した意匠部品５８を有する。 The light emitting device 37A of the first illumination unit 28a includes a red LED unit 56A, a light shielding case 57A, and a design component 58, as shown in FIG. An opening (not shown) is formed in the light shielding case 57A. The light shielding case 57A is arranged at a position slightly apart from the design surface 58a of the design part 58 (specifically, the inner wall surface of the design part 58 corresponding to this design part), and is configured integrally with the design part 58. It is. In FIG. 5, the light emitting device 37 </ b> A and the light emitting device 37 </ b> B are illustrated so as to share a single design component 58. However, FIG. 5 is a diagram conceptually showing the internal structure of the light emitting device 37A and the light emitting device 37B. Actually, as shown in FIG. 4, the light emitting device 37A and the light emitting device 37B are members independent of each other. The design parts 58 are independent from each other.
　赤色ＬＥＤユニット５６Ａが発光し、この光が遮光ケース５７Ａの開口部を経由して意匠面５８ａを発光させることにより、図４に示すように、発光器具３７Ａの部位に、赤色の表示を形成できる。なお、図４では、この表示の一例として意匠面５８ａにあらかじめ設けられているドアオープンの警告マークが発光している様子が示されている。 The red LED unit 56A emits light, and this light causes the design surface 58a to emit light through the opening of the light shielding case 57A, whereby a red display can be formed at the site of the light emitting device 37A as shown in FIG. . FIG. 4 shows a state in which a door open warning mark provided in advance on the design surface 58a emits light as an example of this display.
　第１照明部２８ａの発光器具３７Ｂは、図５に示すように、マルチカラーＬＥＤユニット５６Ｂと、指針状導光体１８と、遮光ケース５７Ｂと、意匠部品５８とを有している。また、発光器具３７Ｃの構成は発光器具３７Ｂと実質的に同様であるが、配置する向きが図４に示すように大きく異なっている。 The light emitting device 37B of the first illumination unit 28a includes a multi-color LED unit 56B, a pointer-shaped light guide 18, a light shielding case 57B, and a design component 58, as shown in FIG. The configuration of the light emitting device 37C is substantially the same as that of the light emitting device 37B, but the arrangement direction is greatly different as shown in FIG.
　図１（ａ）、図１（ｂ）及び図１（ｃ）に示した指針ユニット１５と同様に、発光器具３７Ｂの指針状導光体１８も、光導入部１８ａおよび発光面１８ｂを有している。また、発光器具３７Ｂの遮光ケース５７Ｂも遮光ケース１９と同様に線状の開口部を有している。マルチカラーＬＥＤユニット５６Ｂは、Ｒ（赤色）、Ｇ（緑色）及びＢ（青色）等の光を発光する複数色のＬＥＤ素子を内蔵しているので、発光色の制御が可能である。 Similar to the pointer unit 15 shown in FIGS. 1A, 1B, and 1C, the pointer-shaped light guide 18 of the light emitting device 37B also has a light introducing portion 18a and a light emitting surface 18b. ing. Further, the light shielding case 57B of the light emitting device 37B also has a linear opening similarly to the light shielding case 19. Since the multi-color LED unit 56B incorporates LED elements of a plurality of colors that emit light such as R (red), G (green), and B (blue), the emission color can be controlled.
　発光器具３７Ｂの指針状導光体１８は、マルチカラーＬＥＤユニット５６Ｂが出射した光を導入して発光面１８ｂに導くので、遮光ケース５７Ｂの開口部から意匠面５８ａに向かって光を出射することができる。発光器具３７Ｂの遮光ケース５７Ｂは、意匠部品５８と一体に構成してあるが、意匠面５８ａ（具体的には、この意匠部位に対応する意匠部品５８の内壁面）と遮光ケース５７Ｂとの間は所定距離だけ離間した状態で配置されている。 Since the pointer-shaped light guide 18 of the light emitting device 37B introduces the light emitted from the multi-color LED unit 56B and guides it to the light emitting surface 18b, the light is emitted from the opening of the light shielding case 57B toward the design surface 58a. Can do. The light shielding case 57B of the light emitting device 37B is configured integrally with the design component 58, but between the design surface 58a (specifically, the inner wall surface of the design component 58 corresponding to the design portion) and the light shielding case 57B. Are arranged with a predetermined distance apart.
　第２照明部２８ｂの発光器具３８Ｂは、図６に示すように、回路基板７６上に固定されたＬＥＤユニット７７と、指針状導光体７８と、支持部品７８Ｂと、遮光ケース７９と、意匠部品５８Ｂとで構成されている。また、図４に示した他の発光器具３８Ａ、３８Ｃ、３８Ｄ、３８Ｅ及び３８Ｆも、図６に示した発光器具３８Ｂと同様の構成であり、配置する向きだけがそれぞれ異なっている。 As shown in FIG. 6, the light emitting device 38B of the second illumination unit 28b includes an LED unit 77 fixed on the circuit board 76, a pointer-shaped light guide 78, a support component 78B, a light shielding case 79, and a design. It consists of a part 58B. Further, the other light emitting devices 38A, 38C, 38D, 38E and 38F shown in FIG. 4 have the same configuration as the light emitting device 38B shown in FIG.
　なお、図６においては分解した状態を示してあり、実際には指針状導光体７８の光導入部がＬＥＤユニット７７の光出射面と隣接する位置に配置される。また、遮光ケース７９は、その開口部を除いて指針状導光体７８を覆うように配置される。また、図６に示したように、遮光ケース７９の外側の面（発光面）は、意匠部品５８Ｂの意匠面５８Ｂａ（具体的には、この意匠部位に対応する意匠部品５８の内壁面）に当接する位置に配置してある。 FIG. 6 shows a disassembled state, and in actuality, the light introducing portion of the pointer-shaped light guide 78 is disposed at a position adjacent to the light emitting surface of the LED unit 77. Further, the light shielding case 79 is disposed so as to cover the pointer-shaped light guide 78 except for the opening. Further, as shown in FIG. 6, the outer surface (light emitting surface) of the light shielding case 79 is on the design surface 58Ba of the design component 58B (specifically, the inner wall surface of the design component 58 corresponding to this design part). It arrange | positions in the position which contact | abuts.
　図４に示した第２照明部２８ｂの発光器具３８Ａ、３８Ｂ、３８Ｃ、３８Ｄ、３８Ｅ及び３８Ｆの各々のＬＥＤユニット７７は、共通の回路基板７６上に全て配置されている。したがって、この回路基板７６の制御により、６個の発光器具３８Ａ～３８Ｆの点灯／消灯等の状態を互いに連携するように制御することが容易である。 The LED units 77 of the light emitting devices 38A, 38B, 38C, 38D, 38E, and 38F of the second illumination unit 28b shown in FIG. 4 are all arranged on a common circuit board 76. Therefore, by controlling the circuit board 76, it is easy to control the lighting / extinguishing states of the six light emitting devices 38A to 38F so as to cooperate with each other.
＜発光状態の具体例＞
　図４に示した照明オーナメントの一部分における発光例を図７に示す。 <Specific example of light emission state>
FIG. 7 shows a light emission example in a part of the illumination ornament shown in FIG.
　図７に示した発光例は、図４に示した第２照明部２８ｂの発光器具３８Ａ、３８Ｂ、３８Ｃ、３８Ｄ、３８Ｅ及び３８Ｆの発光制御により実現する。つまり、図７に示す針状発光部８６（１）、８６（２）、８６（３）及び８６（４）は、それぞれ発光器具３８Ａ、３８Ｂ、３８Ｃ及び３８Ｄを発光させることにより、針状の明るい意匠または表示としてユーザに視認される。 7 is realized by the light emission control of the light emitting devices 38A, 38B, 38C, 38D, 38E and 38F of the second illumination unit 28b shown in FIG. That is, the needle-like light emitting portions 86 (1), 86 (2), 86 (3), and 86 (4) shown in FIG. 7 emit the needle-like light emitting devices 38A, 38B, 38C, and 38D, respectively. It is visually recognized by the user as a bright design or display.
　また、図６に示すように、発光器具３８Ａ～３８Ｆの各々に含まれる遮光ケース７９は、意匠面５８Ｂａ（具体的には、この意匠部位に対応する意匠部品５８Ｂの内壁面）と当接する位置に配置されている。したがって、ＬＥＤユニット７７の光を効率よく意匠面５８Ｂａに導くことができ、また、遮光ケース７９により輪郭を強調した鮮明な針状の発光パターンとしてユーザに視認される。 Further, as shown in FIG. 6, the light shielding case 79 included in each of the light emitting devices 38A to 38F is in a position where it comes into contact with the design surface 58Ba (specifically, the inner wall surface of the design component 58B corresponding to this design part). Is arranged. Therefore, the light of the LED unit 77 can be efficiently guided to the design surface 58Ba, and is visually recognized by the user as a clear needle-like light emission pattern in which the contour is emphasized by the light shielding case 79.

That is, the occupant can operate the lighting operation unit 20 as necessary, and can individually set the on / off and emission colors of the foot lamp 71, the pocket lamp 72, and the storage lamp 73. .
　例えば、足元照明灯７１を点灯させることで、足元に落としたものを容易に探すことができ、また、車両に対して円滑に昇降することができる。ポケット照明灯７２を点灯させることで、ドアポケット３４内の小物を容易に探すことができ、また、ドア１を閉じるべくドアポケット３４を把持する際にドアポケット３４を容易に認識することができる。収納部照明灯７３を点灯させることで、収納部２４の特にドリンクホルダ部３６の場所を容易に把握することができ、ドリンクホルダ部３６に対するドリンクの出し入れを容易に行うことができる。 For example, by turning on the foot illumination lamp 71, it is possible to easily find what has been dropped on the foot, and to move up and down smoothly with respect to the vehicle. By turning on the pocket illumination lamp 72, it is possible to easily search for small items in the door pocket 34 and to easily recognize the door pocket 34 when gripping the door pocket 34 to close the door 1. . By turning on the storage section illumination lamp 73, it is possible to easily grasp the location of the storage section 24, particularly the drink holder section 36, and to easily put in and out the drink holder section 36.
　以上、説明したように、本実施形態に係る車内照明装置１０によれば、ドア１が開状態であるときに、第一制御コネクタ４５の第一制御装置によって、ドア警告灯４１、ドアハンドル照明灯４２及び装飾灯４３が、例えば、赤色や黄色等の所定の警報色で点灯される。なお、第二制御コネクタ７５の第二制御装置は、ドア１の開状態において、足元照明灯７１、ポケット照明灯７２、収納部照明灯７３を警報色により点灯するようにしてもよい。これにより、ドア１の開状態において、ドア警告灯４１、ドアハンドル照明灯４２、装飾灯４３に併せ、足元照明灯７１、ポケット照明灯７２、収納部照明灯７３も警報色により点灯するので、車内のより広範囲において乗員に対し警告することができる。 As described above, according to the in-vehicle illumination device 10 according to the present embodiment, when the door 1 is in the open state, the first control device of the first control connector 45 causes the door warning light 41 and the door handle illumination. The lamp 42 and the decorative lamp 43 are turned on with a predetermined alarm color such as red or yellow. Note that the second control device of the second control connector 75 may turn on the foot illumination lamp 71, the pocket illumination lamp 72, and the storage section illumination lamp 73 with an alarm color when the door 1 is open. Thereby, in the open state of the door 1, in addition to the door warning light 41, the door handle illumination light 42, and the decoration light 43, the foot illumination light 71, the pocket illumination light 72, and the storage unit illumination light 73 are also lit with an alarm color. A warning can be given to the occupant in a wider area in the vehicle.
　一般に、ドア１の開状態は、メータ周りの警告灯が点灯することで乗員に警報する。また、近年では、ドアハンドル２１近傍にドア警告灯が設けられる場合もある。しかし、これらの警告灯では、乗員へ警報が十分に伝達されないおそれがある。 Generally, when the door 1 is open, a warning light around the meter is lit to alert the occupant. In recent years, a door warning light may be provided near the door handle 21. However, with these warning lights, there is a possibility that the warning is not sufficiently transmitted to the occupant.
　これに対して、本実施形態では、ドア１の開状態時に、ドア警告灯４１だけでなく、ドアハンドル２１を照明するドアハンドル照明灯４２及び装飾光を発光する装飾灯４３がドア警告灯４１とともに所定の警報色で点灯されるので、ドア１の開状態を乗員へ確実に伝達させることができる。 On the other hand, in the present embodiment, when the door 1 is in the open state, not only the door warning light 41 but also the door handle lighting light 42 that illuminates the door handle 21 and the decorative light 43 that emits decorative light include the door warning light 41. At the same time, it is turned on with a predetermined warning color, so that the open state of the door 1 can be reliably transmitted to the occupant.
　また、ドア１が閉じられた際に、警報色で点灯していたドア警告灯４１、ドアハンドル照明灯４２及び装飾灯４３が警報色と異なる色での点灯または消灯を行うことにより、車両の乗員は、ドア１が閉じられたことを確実に認識することができる。 Further, when the door 1 is closed, the door warning light 41, the door handle illumination light 42, and the decoration light 43, which have been lit in the warning color, are turned on or off in a color different from the warning color, thereby The occupant can reliably recognize that the door 1 is closed.
　また、本実施形態に係る車内照明装置１０によれば、乗員が必要に応じて足元照明灯７１、ポケット照明灯７２及び収納部照明灯７３を点消灯することができる。これにより、利便性を高めることができる。 Moreover, according to the vehicle interior illumination device 10 according to the present embodiment, the occupant can turn off the foot illumination lamp 71, the pocket illumination lamp 72, and the storage section illumination lamp 73 as necessary. Thereby, the convenience can be improved.
　しかも、第二制御コネクタ７５の第二制御装置が、足元照明灯７１、ポケット照明灯７２及び収納部照明灯７３に繋がるハーネス８１，８２，８３にコネクタ接続されて吸音パネル４に一体的に設けられてドア１の内部に組み付けられるので、ドア１への配線作業性を大幅に向上させることができる。 Moreover, the second control device of the second control connector 75 is connected to the harnesses 81, 82, 83 connected to the foot illumination lamp 71, the pocket illumination lamp 72, and the storage section illumination lamp 73 so as to be provided integrally with the sound absorbing panel 4. Therefore, the wiring workability to the door 1 can be greatly improved.
　なお、上記実施形態において、乗員は、照明操作部２０を操作して車内照明装置１０を、各種の点灯モードに設定することができ、第一制御コネクタ４５の第一制御装置及び第二制御コネクタ７５の第二制御装置は、設定された点灯モードで第一照明ユニット１１及び第二照明ユニット１２を点灯させる。例えば、車外の風景に応じて発光色及び照度を選択して点灯させる風景モード、車内温度に応じて発光色及び照度を選択して点灯させる車内温度モード、車速に応じて発光色及び照度を選択して点灯させる車速モード、車外の明るさに応じて発光色及び照度を選択して点灯させる外部明度モード、スポーツモード、ＥＣＯモード、ノーマルモード等のドライブモードに応じて発光色及び照度を選択して点灯させるドライブ連動モードなどに設定可能である。 In the above embodiment, the occupant can operate the lighting operation unit 20 to set the interior lighting device 10 to various lighting modes, and the first control device 45 and the second control connector of the first control connector 45. The second control device 75 lights the first lighting unit 11 and the second lighting unit 12 in the set lighting mode. For example, a landscape mode in which the light emission color and illuminance are selected and turned on according to the scenery outside the vehicle, a car interior temperature mode in which the light emission color and illuminance are selected according to the vehicle interior temperature, and a light emission color and illuminance are selected according to the vehicle speed. Select the luminescent color and illuminance according to the drive mode such as the vehicle speed mode to be lit, the external lightness mode to be lit by selecting the luminescent color and illuminance according to the brightness outside the vehicle, the sport mode, ECO mode, normal mode, etc. It can be set to drive-linked mode that lights up.
　また、図１５に示すように、車両には、センターコンソール９０に足元照明灯９１を設けても良い。具体的には、センターコンソール９０のケース９２の裏側に光源９１Ｌを設け、この光源９１Ｌを、ケース９２と車両の底部に設けられたマット９４との隙間へ向けて配置する。このようにすれば、光源９１Ｌの光がケース９２とマット９４との隙間から車内の底部へ導かれ、乗員の足元が照明される。 Further, as shown in FIG. 15, a foot illumination lamp 91 may be provided on the center console 90 in the vehicle. Specifically, a light source 91L is provided on the back side of the case 92 of the center console 90, and the light source 91L is disposed toward a gap between the case 92 and a mat 94 provided at the bottom of the vehicle. In this way, the light from the light source 91L is guided from the gap between the case 92 and the mat 94 to the bottom of the vehicle, and the feet of the passenger are illuminated.
　このように、ドア１及びセンターコンソール９０に足元照明灯７１，９１を設ければ、図１６に示すように、車両Ｓの乗員の足元の広範囲を複数方向（前後左右）からまんべんなく照らすことができ、足元に落としたものなどを容易に確認できる。また、複数の光源で照明するので、一つの光源での輝度を抑えることができる。 In this way, if the foot lamps 71 and 91 are provided on the door 1 and the center console 90, as shown in FIG. , You can easily check what was dropped at your feet. Moreover, since it illuminates with several light sources, the brightness | luminance with one light source can be suppressed.

FIG. 17 is a schematic configuration diagram of the interior lighting device.

The door 1 has a door handle 21 and an armrest 22, and the armrest 22 is provided with a door pocket 34. The interior lighting device 110 is provided in the vicinity of the upper edge of the interior panel 2 of the door 1 above the door handle 21 and is arranged in a line along the front-rear direction of the vehicle.
　図１７に示すように、車内照明装置１１０は、制御コネクタ１２０と、複数の光源ユニット１３０とを備えている。本例では、４個の光源ユニット１３０を備えている。 As shown in FIG. 17, the in-vehicle illumination device 110 includes a control connector 120 and a plurality of light source units 130. In this example, four light source units 130 are provided.
　制御コネクタ１２０は、制御装置を備えたコネクタである。この制御コネクタ１２０には、ＥＣＵ（図示略）からの通信線１２１が接続されている。この制御コネクタ１２０は、６つの出力ポート１２０ａを備えている。 The control connector 120 is a connector provided with a control device. A communication line 121 from an ECU (not shown) is connected to the control connector 120. The control connector 120 includes six output ports 120a.
　光源ユニット１３０は、それぞれ光源１３１と、導光部材１３２と、コネクタ１３３とを備えている。導光部材１３２は、図１（ｂ）に示した指針状導光体１８に相当する。光源１３１は、ＬＥＤ（Ｌｉｇｈｔ　Ｅｍｉｔｔｉｎｇ　Ｄｉｏｄｅ）等の発光素子を有している。光源１３１は、赤、緑、青の三原色の光を発光するマルチカラーＬＥＤである。導光部材１３２は、導光性を有する樹脂を棒状に形成したものである。導光部材１３２には、光源１３１からの光が入光される。この導光部材１３２は、一部が車内に露出するようにドア１の内装パネル２に固定されており、一列に配置されている。コネクタ１３３には、制御コネクタ１２０からの制御線１２２及びバッテリ（図示略）から延びる電源線１２３が接続されている。このコネクタ１３３には、光源１３１が接合されており、光源１３１には、制御線１２２からの制御信号が送信され、電源線１２３からの電力が供給される。 The light source unit 130 includes a light source 131, a light guide member 132, and a connector 133, respectively. The light guide member 132 corresponds to the pointer-shaped light guide 18 shown in FIG. The light source 131 includes a light emitting element such as an LED (Light Emitting Diode). The light source 131 is a multi-color LED that emits light of three primary colors of red, green, and blue. The light guide member 132 is formed of a resin having a light guide property in a rod shape. Light from the light source 131 enters the light guide member 132. The light guide member 132 is fixed to the interior panel 2 of the door 1 so that a part thereof is exposed in the vehicle, and is arranged in a line. The connector 133 is connected to a control line 122 from the control connector 120 and a power line 123 extending from a battery (not shown). A light source 131 is joined to the connector 133, and a control signal from the control line 122 is transmitted to the light source 131 and power from the power supply line 123 is supplied.
　制御線１２２は、制御コネクタ１２０の出力ポート１２０ａに接続されている。制御コネクタ１２０から延びる制御線１２２は、赤用制御線１２２Ｒ、緑用制御線１２２Ｇ、青用制御線１２２Ｂを有している。赤用制御線１２２Ｒは、それぞれの光源ユニット１３０に個別に接続される制御線である。制御コネクタ１２０の出力ポート１２０ａには、４本の赤用制御線１２２Ｒが接続されており、それぞれ光源ユニット１３０に導かれている。緑用制御線１２２Ｇ及び青用制御線１２２Ｂは、それぞれの光源ユニット１３０へ一括して接続される制御線である。緑用制御線１２２Ｇ及び青用制御線１２２Ｂは、制御コネクタ１２０側が１本とされ、それぞれ途中で４本に分岐されている。緑用制御線１２２Ｇ及び青用制御線１２２Ｂは、制御コネクタ１２０の出力ポート１２０ａに接続されており、分岐された４本が４個の光源ユニット１３０にそれぞれ接続されている。 The control line 122 is connected to the output port 120a of the control connector 120. The control lines 122 extending from the control connector 120 include a red control line 122R, a green control line 122G, and a blue control line 122B. The red control line 122R is a control line connected to each light source unit 130 individually. Four red control lines 122R are connected to the output port 120a of the control connector 120, and are led to the light source unit 130, respectively. The green control line 122G and the blue control line 122B are control lines connected to the respective light source units 130 at once. The green control line 122G and the blue control line 122B have one control connector 120, and each branch into four on the way. The green control line 122G and the blue control line 122B are connected to the output port 120a of the control connector 120, and the four branched lines are connected to the four light source units 130, respectively.
　上記の車内照明装置１１０では、制御コネクタ１２０の制御装置によって各光源ユニット１３０の光源１３１の点消灯及び輝度が制御される。そして、光源ユニット１３０の光源１３１が点灯されることで、内装パネル２に設けられた光源ユニット１３０のそれぞれの導光部材１３２が発光し、ライン状に光るイルミネーションが得られる。 In the interior lighting device 110 described above, the light source 131 of each light source unit 130 is turned on and off and the brightness is controlled by the control device of the control connector 120. Then, when the light source 131 of the light source unit 130 is turned on, each light guide member 132 of the light source unit 130 provided in the interior panel 2 emits light, and illumination that shines in a line shape is obtained.
　次に、制御コネクタ１２０による光源ユニット１３０の制御について説明する。図１８は、制御装置による光源ユニットの制御について説明する色彩を表すグラフである。 Next, control of the light source unit 130 by the control connector 120 will be described. FIG. 18 is a graph showing colors for explaining control of the light source unit by the control device.
＜グラデーション点灯モード＞
　グラデーション点灯モードになると、制御コネクタ１２０の制御装置によって、それぞれの光源ユニット１３０は、緑色及び青色の所定の二色の点消灯及び輝度が共通して同一に制御されるとともに、所定の二色以外の残りの赤色の点消灯及び輝度が個別に制御される。これにより、図１８に示すように、各光源ユニット１３０では、例えば、青色及び緑色に対して赤色が強弱範囲Ａの輝度で混合されたそれぞれ異なる混合色で点灯される。これにより、車内照明装置１１０では、それぞれの導光部材１３２が、緑色及び青色の二色に赤色が異なる輝度で混合された様々な混合色によって発光することで、グラデーションがかけられたライン状のイルミネーションが得られる。 <Gradation lighting mode>
When the gradation lighting mode is set, the light source unit 130 is controlled by the control device of the control connector 120 so that the lighting and lighting of the two predetermined colors of green and blue are the same in common and the brightness is other than the predetermined two colors. The remaining red on / off and brightness are individually controlled. Accordingly, as shown in FIG. 18, in each light source unit 130, for example, red is mixed with different mixed colors in which red and green are mixed with luminance in the intensity range A. As a result, in the vehicle interior lighting device 110, each light guide member 132 emits light with various mixed colors in which red and green are mixed with two different colors of green and blue, thereby forming a line shape with gradation. Illumination is obtained.
＜通常点灯モード＞
　通常点灯モードになると、制御コネクタ１２０の制御装置によって、全ての光源ユニット１３０が同一色（例えば、赤色、緑色、青色または各色の混合色等）で点灯される。これにより、それぞれの導光部材１３２が同一色で発光することで、その発光色でライン状に光るイルミネーションが得られる。 <Normal lighting mode>
In the normal lighting mode, all the light source units 130 are lit in the same color (for example, red, green, blue, or a mixed color of each color) by the control device of the control connector 120. Thereby, when each light guide member 132 emits light with the same color, illumination that shines in a line shape with the emitted light color is obtained.
　ここで、参考例に係る車内照明装置１１０Ｓについて説明する。
　図１９は、参考例に係る車内照明装置の概略構成図である。 Here, the interior lighting device 110S according to the reference example will be described.
FIG. 19 is a schematic configuration diagram of an interior lighting device according to a reference example.
　図１９に示すように、参考例に係る車内照明装置１１０Ｓでは、６つの出力ポート１２０ａを有する二つの制御コネクタ１２０を備えており、それぞれの制御コネクタ１２０に、２組の光源ユニット１３０に繋がる２本の赤用制御線１２２Ｒ、２本の緑用制御線１２２Ｇ及び２本の青用制御線１２２Ｂが接続されている。 As shown in FIG. 19, the in-vehicle illumination device 110S according to the reference example includes two control connectors 120 having six output ports 120a, and each control connector 120 is connected to two sets of light source units 130. Two red control lines 122R, two green control lines 122G, and two blue control lines 122B are connected.
　この参考例に係る車内照明装置１１０Ｓでは、制御コネクタ１２０の制御装置は、それぞれの光源ユニット１３０における光源１３１の制御を、赤色、緑色及び青色の三色を個別に制御して輝度を強弱させる。これにより、それぞれの導光部材１３２が、赤色、緑色及び青色の三色が混合された様々な混合色によって発光され、グラデーションがかけられたイルミネーションが得られる。 In the in-vehicle illumination device 110S according to this reference example, the control device of the control connector 120 controls the light source 131 in each light source unit 130 to individually control the three colors of red, green, and blue to increase or decrease the luminance. Thereby, each light guide member 132 emits light by various mixed colors in which three colors of red, green, and blue are mixed, and illumination with gradation is obtained.
　ところで、この参考例に係る車内照明装置１１０Ｓでは、それぞれの光源ユニット１３０を個別に制御するために、制御の複雑化を招き、また、複雑な制御を行うために、制御コネクタ１２０や制御線１２２などの部品数も増大する。このため、コストが嵩んでしまう。また、各色の発光を個別に制御するので、各色の光に色味のばらつきが生じてしまう。 By the way, in the vehicle interior lighting device 110S according to this reference example, the control connector 120 and the control line 122 are used in order to control each light source unit 130 individually and to make the control complicated and to perform complicated control. The number of parts increases. For this reason, cost will increase. In addition, since light emission of each color is individually controlled, variations in color occur in the light of each color.
　これに対して、前述の車内照明装置１１０によれば、複数の光源ユニット１３０における光源１３１で発光可能な三原色のうちの所定の二色を発光させた状態で、残りの一色を様々な輝度で発光させることにより、所定の二色の色味のばらつきを抑えつつ、グラデーションがかけられたイルミネーションで高い装飾効果を得ることができる。しかも、複数の光源ユニット３０における三原色のうちの所定の二色である緑及び青を同一制御とし、残りの一色である赤を個別に制御するので、制御を簡略化することができ、制御回路の部品数の低減を図り、コストを抑えることができる。 On the other hand, according to the above-described interior illumination device 110, the remaining one color is emitted with various luminances in a state where predetermined two colors of the three primary colors that can be emitted by the light source 131 in the plurality of light source units 130 are emitted. By making it emit light, it is possible to obtain a high decorative effect with gradationed illumination while suppressing variations in the colors of two predetermined colors. In addition, since green and blue, which are predetermined two colors among the three primary colors in the plurality of light source units 30, are set to the same control and red, which is the remaining one color, is individually controlled, the control can be simplified, and the control circuit The number of parts can be reduced and the cost can be reduced.
　特に、ドア１の内装パネル２における互いに近接した位置に設けられた複数の光源ユニット１３０の棒状の導光部材１３２が、グラデーションがかけられて発光することで、高い装飾効果を得ることができる。 Particularly, when the bar-shaped light guide members 132 of the plurality of light source units 130 provided at positions close to each other in the interior panel 2 of the door 1 emit light with gradation, a high decorative effect can be obtained.
　なお、上記説明では、各光源ユニット１３０の発光制御を、緑色及び青色の二色を所定の二色として共通制御し、赤色を個別制御することでグラデーション点灯を行ったが、個別制御を行うのは赤色に限らない。 In the above description, the light emission control of each light source unit 130 is commonly controlled by using two colors of green and blue as predetermined two colors, and gradation lighting is performed by individually controlling red, but individual control is performed. Is not limited to red.
　例えば、赤色及び緑色の二色を所定の二色として共通制御し、青色を個別制御することで、図２０（ａ）に示すように、青色が強弱範囲Ａの輝度で混合されたそれぞれ異なる混合色で点灯させても良く、また、赤色及び青色の二色を所定の二色として共通制御し、緑色を個別制御することで、図２０（ｂ）に示すように、緑色が強弱範囲Ａの輝度で混合されたそれぞれ異なる混合色で点灯させても良い。 For example, two different colors, red and green, are commonly controlled as two predetermined colors, and blue is individually controlled. As shown in FIG. It may be lit in a color, and two colors of red and blue are commonly controlled as two predetermined colors, and green is individually controlled, so that green is in the strength range A as shown in FIG. You may make it light by each different mixed color mixed with the brightness | luminance.

In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.
