Description

本発明は、車両用室内灯に関する。より具体的には、車室に固定される灯具ボディ内に設けられた光源から車室内に向けて光を照射するともに、光源を覆う透光カバーの表面に人の指などを接触させることにより光源のオンまたはオフなどの操作が可能な車両用室内灯に関する。   The present invention relates to a vehicle interior lamp. More specifically, by irradiating light from the light source provided in the lamp body fixed to the vehicle interior toward the vehicle interior, and bringing a human finger or the like into contact with the surface of the translucent cover that covers the light source The present invention relates to a vehicle interior light that can be operated to turn on or off a light source.

自動車の車室の天井面などには、車室内を照明するための室内灯が設けられている。従来の室内灯では、例えば特許文献1に記載された車両用室内灯のように、点灯および消灯などの操作は、照射面の近傍に設けられたプッシュボタンを操作することにより行われる。また、光量を調整可能な室内灯でも、光量を調整するための調整つまみなどは、上記プッシュボタンと同様に照射面の近傍などに設けられていた。   An interior lamp for illuminating the interior of the vehicle is provided on the ceiling surface of the interior of the automobile. In a conventional room light, for example, as in a vehicle interior light described in Patent Document 1, operations such as turning on and off are performed by operating a push button provided in the vicinity of an irradiation surface. In addition, even in a room light whose light quantity can be adjusted, an adjustment knob or the like for adjusting the light quantity has been provided in the vicinity of the irradiation surface as in the case of the push button.

特開2004−284511号公報JP 2004-284511 A

上記のような従来の室内灯では、消灯状態から点灯操作を行う場合などでは車室内が暗くプッシュボタンや調整つまみが見えにくいことが課題であった。   In the conventional interior lights as described above, when the lighting operation is performed from the off state, the interior of the vehicle is dark and it is difficult to see the push button and the adjustment knob.

本発明は、上記課題を解決することを目的として、車室に固定される灯具ボディと、前記灯具ボディ内に設けられた光源と、前記光源を覆うように配されるとともに前記光源から前記車室内に向けて出射される光を透光する透光部を有し、前記透光部における前記灯室側の面の少なくとも一部に透光導電膜が形成された透光カバーと、前記透光カバーにおける少なくとも前記透光部の側方に配され、接触体が前記透光部の前記車室側の面に接触することによる前記透光導電膜と前記接触体との間に形成される静電容量を検知することによって前記光源の点灯状態を制御する点灯状態制御部と、を備え、前記透光カバーは、側方に延出する延出部を有し、前記透光導電膜の一部は、前記延出部まで延出して形成されて前記点灯状態制御部と電気的に接続されることを特徴とする車両用室内灯を提供する。   In order to solve the above-described problems, the present invention provides a lamp body fixed to a passenger compartment, a light source provided in the lamp body, a light source provided in the lamp body and covering the light source and from the light source to the vehicle. A translucent cover having a translucent portion that transmits light emitted toward the room, and having a translucent conductive film formed on at least a part of the surface of the translucent portion on the lamp chamber side; and the translucent cover. The light cover is disposed at least on the side of the light transmitting portion, and is formed between the light transmitting conductive film and the contact body by a contact body contacting a surface of the light transmitting portion on the vehicle interior side. A lighting state control unit that controls a lighting state of the light source by detecting a capacitance, and the translucent cover has an extending portion that extends laterally, and the translucent conductive film A part is formed to extend to the extension part, and is electrically connected to the lighting state control part. It is connected to provide a room lamp for a vehicle according to claim to.

このような車両用室内灯によれば、透光カバーにおける裏側に透光導電膜が形成された部分(タッチ操作面)を指で触れるだけで点灯や光量調整などの操作を行うことができるので、プッシュボタンや調整つまみを操作する場合と比べて特に暗い車室内での操作性が向上する。また、静電容量を検知して光源の点灯状態を制御する点灯状態制御部を透光カバーにおける少なくとも透光部の側方に配置することで、灯室内(透光部の裏側)の構成の自由度が増す。すなわち、例えば、点灯状態制御部を灯室内や灯具ボディの後方側に配置して透光導電膜と点灯状態制御部とを電気的に接続させる構成を透光部の裏側(灯室内)に設ける場合と比べて、透光部の裏側にインナーレンズなどを配置し易い。また、点灯状態制御部を透光カバーの側方に配置することで、点灯状態制御部をオーバーヘッドコンソールの裏側に隠して車室内から見えないようにすることができるとともに、灯具の車両天井面からの厚さをより小さくすることができる。   According to such a vehicle interior light, operations such as lighting and light amount adjustment can be performed simply by touching a portion (touch operation surface) where the transparent conductive film is formed on the back side of the transparent cover with a finger. As compared with the case where the push button or the adjustment knob is operated, the operability particularly in the dark interior is improved. In addition, the lighting state control unit that detects the capacitance and controls the lighting state of the light source is disposed at least on the side of the light transmitting part in the light transmitting cover, so that the configuration of the lamp chamber (the back side of the light transmitting part) is configured. Increased freedom. That is, for example, a configuration in which the lighting state control unit is disposed on the rear side of the lamp chamber or the lamp body and the light-transmitting conductive film and the lighting state control unit are electrically connected is provided on the back side (lamp chamber) of the light-transmitting unit. Compared to the case, it is easier to arrange an inner lens or the like on the back side of the translucent part. In addition, by arranging the lighting state control unit on the side of the translucent cover, the lighting state control unit can be hidden behind the overhead console so that it cannot be seen from the interior of the vehicle. The thickness of can be made smaller.

また、上記車両用室内灯において、前記光源と前記透光部との間には、インナーレンズが配設されることが好ましい。   In the vehicle interior light, it is preferable that an inner lens is disposed between the light source and the light transmitting portion.

これにより、光源からの熱が透光カバーにおけるタッチ操作面に伝わりにくくすることができる。   Thereby, the heat from a light source can be made difficult to be transmitted to the touch operation surface in a translucent cover.

また、上記車両用室内灯において、前記延出部における前記車室と反対側には、前記透光部内面に対して45度以下の角度で傾斜する傾斜面が設けられており、前記透光導電膜の一部は、前記傾斜面にも形成されていることが好ましい。   In the vehicular interior light, an inclined surface that is inclined at an angle of 45 degrees or less with respect to the inner surface of the light-transmitting portion is provided on the opposite side of the extension portion from the vehicle compartment. It is preferable that a part of the conductive film is also formed on the inclined surface.

これにより、例えば透光カバーの側方の車両天井面に点灯状態制御部を構成する回路基板を固定したことにより、回路基板の電極と透光部に形成された透光導電膜とが灯室の前後方向に離れた構造となる場合でも、延出部における車室と反対側の傾斜面に形成された透光導電膜を介して回路基板の電極と透光部に形成された透光導電膜とを容易に接続することができる。また、延出部における傾斜面の角度を透光部内面に対して45度以下とすることで、例えばスパッタリングや蒸着などの成膜方法を用いて透光導電膜を延出部に形成し易い。   Thus, for example, by fixing the circuit board constituting the lighting state control unit to the vehicle ceiling surface on the side of the translucent cover, the electrode of the circuit board and the translucent conductive film formed on the translucent part are connected to the lamp chamber. Even when the structure is separated in the front-rear direction, the translucent conductive formed on the electrode of the circuit board and the translucent part through the translucent conductive film formed on the inclined surface on the opposite side of the passenger compartment in the extension part The membrane can be easily connected. Further, by setting the angle of the inclined surface in the extending portion to 45 degrees or less with respect to the inner surface of the light transmitting portion, it is easy to form the light transmitting conductive film on the extending portion by using a film forming method such as sputtering or vapor deposition. .

More specifically, for example, the electronic component 421 is electrically connected to a portion of the light transmitting conductive film 251 formed on the inclined surface of the extending portion 261 via the metal plate 600. Similarly, the electronic components 422 and 423 are electrically connected to the portions formed on the inclined surfaces of the extending portions 262 and 263 of the light-transmitting conductive films 252 and 253 through the metal plate 600, respectively.

Each control circuit includes a contact body such as a human finger between the translucent conductive films 251, 252, and 253 and the contact body formed by contacting the outer surface of the translucent portion 210 (the surface on the passenger compartment side). While detecting the electrostatic capacitance to be formed, the lighting state of the light sources 311, 312, 313 is controlled in accordance with the change in the electrostatic capacitance.

より具体的には、例えば、透光部210の外面における内側に透光導電膜251が形成された部位(タッチ操作面)に指で触れると、透光導電膜251と電気的に接続する電子部品421を含む制御回路は、透光導電膜251と周囲との間に形成されている浮遊容量の変化を検出する。そして、当該制御回路は、浮遊容量の変化が検出されたことに応じて、不図示の光源駆動回路に対して光源311を点灯させるべき旨の信号を出力する。   More specifically, for example, when a finger touches a portion (touch operation surface) where the translucent conductive film 251 is formed on the inner side of the outer surface of the translucent portion 210, electrons that are electrically connected to the translucent conductive film 251. The control circuit including the component 421 detects a change in the stray capacitance formed between the translucent conductive film 251 and the periphery. Then, the control circuit outputs a signal indicating that the light source 311 should be turned on to a light source driving circuit (not shown) in response to detection of a change in stray capacitance.

ここで、上記制御回路は、指が上記部位に触れる度に所定の段階で上記光源駆動回路が光源311に対して供給する電流の大きさを制御してもよい。より具体的には、上記制御回路は、光源311が最も明るく点灯しているときに上記光源駆動回路が光源311に対して供給している電流の大きさを100としたときに、例えば、指が上記部位に触れる度に、当該電流の大きさを0(非点灯)、20、40、60、80、100(最大光量で点灯)と5段階で順次に大きくなるように上記光源駆動回路を制御しても良い。また、この場合、上記制御回路は、光源311が最も明るく点灯しているとき(上記光源駆動回路が光源311に対して供給している電流の大きさが最大(100)のとき)に指が上記部位に触れたことを検出すると、上記光源駆動回路による光源311への電流の供給を停止させて光源311を消灯しても良い。   Here, the control circuit may control the magnitude of the current supplied from the light source driving circuit to the light source 311 at a predetermined stage each time a finger touches the part. More specifically, when the magnitude of the current supplied to the light source 311 by the light source driving circuit is 100 when the light source 311 is lit brightest, the control circuit, for example, Each time the touches the part, the light source driving circuit is adjusted so that the current magnitude increases sequentially in five stages: 0 (non-lighting), 20, 40, 60, 80, 100 (lighting at the maximum light amount). You may control. Further, in this case, the control circuit has a finger when the light source 311 is lit brightest (when the current supplied from the light source driving circuit to the light source 311 is the maximum (100)). When it is detected that the part has been touched, the current supply to the light source 311 by the light source driving circuit may be stopped and the light source 311 may be turned off.

また、これに替えて、上記タッチ操作面に指が連続で触れている時間をカウントするタイマー回路を上記制御回路に設けても良い。この場合、上記制御回路は、上記タッチ操作面に指が連続で触れている時間の長さに応じて上記光源駆動回路が光源311に対して供給している電流の大きさを調整しても良い。   Alternatively, a timer circuit that counts the time that the finger is continuously touching the touch operation surface may be provided in the control circuit. In this case, the control circuit may adjust the magnitude of the current that the light source driving circuit supplies to the light source 311 according to the length of time that the finger continuously touches the touch operation surface. good.

また、光源312,313については、それぞれ、透光部210の外面における内側に透光導電膜252,253が形成された部位に指で触れることで、光源311と同様にその点灯状態が制御される。なお、光源312,313の点灯制御についてはその詳細な説明を省略するが、光源311に対する上記点灯制御と同様であってよい。また、これに替えて、光源312,313に対応する制御回路が、それぞれ別個の制御パターンで対応する光源312,313を制御しても良い。   In addition, the lighting states of the light sources 312 and 313 are controlled in the same manner as the light source 311 by touching a portion where the transparent conductive films 252 and 253 are formed on the inner side of the outer surface of the transparent portion 210 with a finger. The Although detailed description of the lighting control of the light sources 312 and 313 is omitted, the lighting control for the light source 311 may be the same. Alternatively, the control circuits corresponding to the light sources 312 and 313 may control the corresponding light sources 312 and 313 using separate control patterns.

インナーレンズ500は、例えば半透明な樹脂により形成され透光カバー200のすぐ内側(灯具ボディ100の凹部110と透光カバー200によって形成される灯室内における透光カバー200寄り)に配される。なお、本例では、上記のように、点灯状態制御部400を透光カバー200の透光部210に対して側方に設けるとともに、透光カバー200から側方に延出する延出部261,262,263に形成した透光導電膜を介して透光導電膜251,252,253と点灯状態制御部400とを電気的に接続している。   The inner lens 500 is formed of, for example, a translucent resin and is disposed immediately inside the translucent cover 200 (close to the translucent cover 200 in the lamp chamber formed by the concave portion 110 of the lamp body 100 and the translucent cover 200). In the present example, as described above, the lighting state control unit 400 is provided laterally with respect to the translucent part 210 of the translucent cover 200, and the extending part 261 that extends laterally from the translucent cover 200. , 262, 263 are electrically connected to the light-transmitting conductive films 251, 252, 253 through the light-transmitting conductive film.

したがって、例えば、点灯状態制御部400を灯室内や灯具ボディ100の後方側に配置して透光導電膜251,252,253と点灯状態制御部400とを電気的に接続させるための配線などの構成を透光部210の裏側(灯室内)に設ける場合と異なり、本例では、図2および図3に示すように、透光部210の裏側全体にインナーレンズ500を設けることができる。ゆえに、インナーレンズ500は、透光カバー200を透明な素材で形成した場合でも、車室内側から車両用室内灯10を見たときに、灯室内の様々な部材などが見えないようにする役割を担う。これにより、灯室内における光源311,312,313や反射部材151,152,153の形状や配置などの自由度が増すとともに車両用室内灯10全体としての意匠性にも優れる。   Therefore, for example, a wiring for arranging the lighting state control unit 400 in the lamp chamber or the rear side of the lamp body 100 to electrically connect the translucent conductive films 251, 252, 253 and the lighting state control unit 400, etc. Unlike the case where the configuration is provided on the back side (light chamber) of the translucent part 210, in this example, as shown in FIGS. 2 and 3, the inner lens 500 can be provided on the entire back side of the translucent part 210. Therefore, even when the translucent cover 200 is formed of a transparent material, the inner lens 500 serves to prevent various members in the lamp chamber from being seen when the vehicle interior lamp 10 is viewed from the vehicle interior side. Take on. This increases the degree of freedom of the shape and arrangement of the light sources 311, 312, 313 and the reflecting members 151, 152, 153 in the lamp chamber, and is excellent in design as the vehicle interior lamp 10 as a whole.

また、点灯状態制御部400を透光カバー200の側方に配置することで、点灯状態制御部400をオーバーヘッドコンソール1000の裏側に隠して車室内から見えないようにすることができるとともに、車両用室内灯10の車体1100(天井面)からの厚さをより小さくすることができる。また、本例では、透光カバー200の側方における透光部210よりも車体1100(天井面)寄りに点灯状態制御部400を構成する回路基板410を配置したことにより、回路基板410の電極と透光部210に形成された透光導電膜251,252,253とが灯室の前後方向に離れた構造となる。しかしながら、透光カバー200に延出部261,262,263を設けるとともに、延出部261,262,263における車室と反対側の上記傾斜面に透光導電膜251,252,253と一体の透光導電膜を形成することにより、延出部261,262,263を介して回路基板410の電極と透光部210に形成された透光導電膜251,252,253とを容易に電気的に接続することができる。   In addition, by arranging the lighting state control unit 400 on the side of the translucent cover 200, the lighting state control unit 400 can be hidden from the interior of the overhead console 1000 so that it cannot be seen from the vehicle interior. The thickness of the interior lamp 10 from the vehicle body 1100 (ceiling surface) can be further reduced. Further, in this example, the circuit board 410 constituting the lighting state control unit 400 is disposed closer to the vehicle body 1100 (ceiling surface) than the translucent part 210 on the side of the translucent cover 200, so that the electrodes of the circuit board 410 are arranged. The translucent conductive films 251, 252, and 253 formed in the translucent part 210 are separated in the front-rear direction of the lamp chamber. However, the extending portions 261, 262, and 263 are provided on the light-transmitting cover 200, and the light-transmitting conductive films 251, 252, and 253 are integrated with the inclined surfaces of the extending portions 261, 262, and 263 on the side opposite to the passenger compartment. By forming the light-transmitting conductive film, the electrodes of the circuit board 410 and the light-transmitting conductive films 251, 252, and 253 formed on the light-transmitting portion 210 are easily electrically connected via the extending portions 261, 262, and 263. Can be connected to.

また、インナーレンズ500は、光源311,312,313の点灯に伴い発生する熱が透光カバー200に伝わりにくくする役割も担う。これにより、透光カバー200の透光部210における上記タッチ操作面が熱くなりにくいので、指で触れたときに火傷をする虞がない。なお、インナーレンズ500は、二色成形しても良い。より具体的には、例えば、光源311,312,313からの光を出射する部分を透明な樹脂で成形し、それ以外の部分を非透明な(有色の)樹脂により形成することにより、車室内からの見栄えが良くなる。   The inner lens 500 also plays a role of making it difficult for heat generated when the light sources 311, 312, and 313 are turned on to be transmitted to the translucent cover 200. As a result, the touch operation surface of the translucent part 210 of the translucent cover 200 is not easily heated, and there is no risk of burns when touched with a finger. The inner lens 500 may be two-color molded. More specifically, for example, by molding a portion that emits light from the light sources 311, 312, and 313 with a transparent resin, and forming other portions with a non-transparent (colored) resin, The appearance from is improved.

図5は、本発明の実施形態の他の例に係る車両用室内灯11の正面図を示す。また、図6は、図5に示す車両用室内灯11のC−C断面矢視図を示す。図5および図6に示す車両用室内灯11は、図1乃至図4を参照して説明した車両用室内灯10に調光スイッチ121,122を設けた点以外は車両用室内灯10と同様であるので、調光スイッチ121,122以外の構成についてはその説明を省略する。   FIG. 5: shows the front view of the vehicle interior lamp 11 which concerns on the other example of embodiment of this invention. Moreover, FIG. 6 shows a CC cross-sectional arrow view of the vehicle interior lamp 11 shown in FIG. The vehicle interior light 11 shown in FIGS. 5 and 6 is the same as the vehicle interior light 10 except that the light control switches 121 and 122 are provided on the vehicle interior light 10 described with reference to FIGS. 1 to 4. Therefore, the description of the configuration other than the dimming switches 121 and 122 is omitted.

車両用室内灯11は、図5に示すように、灯具ボディ100における凹部110以外の部分に調光スイッチ121,122が設けられている。この調光スイッチ121,122は、図6に調光スイッチ122の断面を示すように、それぞれ、灯具ボディ100から露出したタッチ面126を含むスイッチ本体125と、金属プレート610とを有する。   As shown in FIG. 5, the vehicle interior lamp 11 is provided with dimming switches 121 and 122 at portions other than the recess 110 in the lamp body 100. Each of the dimming switches 121 and 122 includes a switch body 125 including a touch surface 126 exposed from the lamp body 100 and a metal plate 610 as shown in a cross section of the dimming switch 122 in FIG.

スイッチ本体125は、絶縁性の樹脂など電気抵抗の大きな材料で形成されており、灯具ボディ100にビス留めされている。また、金属プレート610は、ステンレスあるいは銅などの導電性を有する材料で形成されており、スイッチ本体125にビス留めされている。また、金属プレート610は、点灯状態制御部400における上記制御回路に電気的に接続されている。   The switch body 125 is made of a material having a large electrical resistance such as an insulating resin and is screwed to the lamp body 100. The metal plate 610 is made of a conductive material such as stainless steel or copper, and is screwed to the switch body 125. Further, the metal plate 610 is electrically connected to the control circuit in the lighting state control unit 400.

したがって、車両用室内灯11では、例えば調光スイッチ121,122のいずれかのタッチ面126に指で触れると、金属プレート610と人体との間に形成される静電容量の変化が上記制御回路によって検出される。そして、上記制御回路は、タッチ面126に指が連続で触れている間だけ、不図示の光源駆動回路が光源311,312,313に供給している電流の大きさを漸増させる。したがって、車両用室内灯11は、タッチ面126に指で触れ続けることで光源311,312,313が徐々に明るく点灯する。   Therefore, in the vehicle interior light 11, for example, when the finger touches any one of the touch surfaces 126 of the dimming switches 121 and 122, a change in the capacitance formed between the metal plate 610 and the human body changes the control circuit. Detected by. The control circuit gradually increases the magnitude of the current supplied to the light sources 311, 312, and 313 by the light source driving circuit (not shown) only while the finger is continuously touching the touch surface 126. Therefore, in the vehicle interior lamp 11, the light sources 311, 312, and 313 are gradually turned on brightly by continuously touching the touch surface 126 with a finger.

なお、車両用室内灯11では、光源311,312,313の光量調整のみを調光スイッチ121,122で行い、光源311,312,313の点灯および消灯については、透光カバー200の透光部210における上記タッチ操作面で行っても良い。また、これに替えて、調光スイッチ121,122で光源311,312,313の点灯および消灯を含む全ての操作が可能であっても良い。   In the vehicle interior lamp 11, only the light amount adjustment of the light sources 311, 312, 313 is performed by the dimming switches 121, 122, and the light transmitting parts of the light transmitting cover 200 are turned on and off. You may perform on the said touch operation surface in 210. FIG. Alternatively, all operations including turning on and off the light sources 311, 312, and 313 may be possible with the dimming switches 121 and 122.

また、本例では、調光スイッチ121,122のいずれかのタッチ面126に指で触れると、光源311,312,313の全ての光量が調整される構成を示したが、光源311,312,313の各々に対応して3つの調光スイッチを設けて各調光スイッチで別個の光源を制御する構成としても良い。   Further, in this example, the configuration in which all the light amounts of the light sources 311, 312, and 313 are adjusted by touching one of the touch surfaces 126 of the dimming switches 121 and 122 with a finger is shown. A configuration may be adopted in which three dimming switches are provided corresponding to each of 313 and a separate light source is controlled by each dimming switch.

図7および図8は、それぞれ、本発明の実施形態のさらに他の例に係る車両用室内灯12および車両用室内灯13における図3に対応する断面図を示す。図7および図8に示す車両用室内灯12および車両用室内灯13は、図1乃至図4を参照して説明した車両用室内灯10とは、透光カバー200の延出部261,262,263の構造と、点灯状態制御部400の構造および取り付け位置の少なくとも何れかが異なる点以外は車両用室内灯10と同様であるので、車両用室内灯12および車両用室内灯13における車両用室内灯10と同じ符号を付した構成については、特に説明しない限りは、車両用室内灯10と同様の構成であるものとする。   FIGS. 7 and 8 are cross-sectional views corresponding to FIG. 3, respectively, of a vehicle interior lamp 12 and a vehicle interior lamp 13 according to still another example of the embodiment of the present invention. The vehicle interior light 12 and the vehicle interior light 13 shown in FIGS. 7 and 8 are different from the vehicle interior light 10 described with reference to FIGS. 1 to 4 in the extending portions 261 and 262 of the translucent cover 200. , 263, and the lighting state control unit 400, except that at least one of the structure and the mounting position is the same as the vehicle interior light 10, so that the vehicle interior light 12 and the vehicle interior light 13 are The components denoted by the same reference numerals as those of the room lights 10 are the same as the vehicle interior lights 10 unless otherwise specified.

図7に示す車両用室内灯12は、車両用室内灯10と同様に、透光カバー200に3つの延出部261,262,263が設けられているが、これらの延出部261,262,263は、車両用室内灯10とは形状が異なる。具体的には、図7に示すように、延出部261,262,263は、車両用室内灯12の透光カバー200の周縁から灯室側に向けて垂直に延びる周縁部220の先端部分から透光カバー200の外側へ向けて折れ曲がった部分である。ここで、延出部261,262,263における車室と反対側の面(傾斜面)と透光部210の内面との成す角度は、45度以下であることが好ましく、本例ではこの範囲において略45度である。なお、本例の延出部261,262,263も、車両用室内灯10の延出部261,262,263と同様に、車室と反対側の傾斜面に、透光導電膜251,252,253から連続する透光導電膜が形成されている。   The vehicle interior light 12 shown in FIG. 7 is provided with three extending portions 261, 262, and 263 in the translucent cover 200, similar to the vehicle interior light 10, but these extending portions 261, 262 are provided. , 263 is different in shape from the vehicle interior lamp 10. Specifically, as shown in FIG. 7, the extending portions 261, 262, and 263 are front end portions of a peripheral portion 220 that extends vertically from the peripheral edge of the translucent cover 200 of the vehicle interior lamp 12 toward the lamp chamber side. It is the part which bent toward the outer side of the translucent cover 200 from. Here, the angle formed by the surface (inclined surface) opposite to the passenger compartment in the extending portions 261, 262, and 263 and the inner surface of the translucent portion 210 is preferably 45 degrees or less, and in this example, this range. Is approximately 45 degrees. Note that the extending portions 261, 262, and 263 of the present example also have the light-transmitting conductive films 251, 252 on the inclined surface on the opposite side to the passenger compartment, like the extending portions 261, 262, and 263 of the vehicle interior lamp 10. , 253, a transparent conductive film is formed.

また、図7に断面構造を示すように、延出部261,262,263の先端部は、導電テープ660で覆われている。この導電テープ660は、良好な電気伝導性を有する材料により形成され、透光導電膜251,252,253が形成された上記傾斜面の一部をも覆っている。また、導電テープ660の外側を覆うように、金属カバー650が取り付けられている。この金属カバー650の外面には、突出部652が突き出ている。そして、この突出部652は、コネクタ640と係合している。このコネクタ640は、点灯状態制御部400の回路基板410に設けられたコネクタ430と接続配線630を介して接続している。したがって、車両用室内灯12においては、透光カバー200の透光部210に形成された透光導電膜251,252,253は、延出部261,262,263の上記傾斜面に形成された透光導電膜、導電テープ660、金属カバー650(突出部652)、コネクタ640、接続配線630、およびコネクタ430を介して点灯状態制御部400と電気的に接続している。   In addition, as shown in the cross-sectional structure of FIG. 7, the distal ends of the extending portions 261, 262, and 263 are covered with a conductive tape 660. The conductive tape 660 is made of a material having good electrical conductivity and also covers a part of the inclined surface on which the light-transmitting conductive films 251, 252, and 253 are formed. A metal cover 650 is attached so as to cover the outside of the conductive tape 660. A protruding portion 652 protrudes from the outer surface of the metal cover 650. The protrusion 652 is engaged with the connector 640. The connector 640 is connected to a connector 430 provided on the circuit board 410 of the lighting state control unit 400 via a connection wiring 630. Therefore, in the vehicle interior lamp 12, the translucent conductive films 251, 252, and 253 formed on the translucent portion 210 of the translucent cover 200 are formed on the inclined surfaces of the extending portions 261, 262, and 263. The lighting state control unit 400 is electrically connected through the light-transmitting conductive film, the conductive tape 660, the metal cover 650 (protrusion 652), the connector 640, the connection wiring 630, and the connector 430.

図8に示す車両用室内灯13は、車両用室内灯10と同様に、透光カバー200に3つの延出部261,262,263が設けられているが、これらの延出部261,262,263は、車両用室内灯10とは形状が異なる。具体的には、図7に示すように、延出部261,262,263は、透光カバー200の周縁から灯室側に向けて垂直に延びる周縁部220の先端部分が透光カバー200の外側へ向けて折れ曲がった部分(傾斜部分)と、当該折れ曲がった部分の先端から透光カバー200の透光部210の面方向と略平行に折れ曲がった部分(平行部分)とで構成される。   The vehicle interior light 13 shown in FIG. 8 is provided with three extending portions 261, 262, 263 on the translucent cover 200, similar to the vehicle interior light 10, but these extending portions 261, 262 are provided. , 263 is different in shape from the vehicle interior lamp 10. Specifically, as illustrated in FIG. 7, the extending portions 261, 262, and 263 are configured such that the distal end portion of the peripheral portion 220 that extends vertically from the peripheral edge of the translucent cover 200 toward the lamp chamber side of the translucent cover 200. It is comprised by the part (inclined part) bent toward the outer side, and the part (parallel part) bent from the front-end | tip of the said bent part substantially parallel to the surface direction of the translucent part 210 of the translucent cover 200.

ここで、延出部261,262,263を構成する上記傾斜部分における車室と反対側の面と透光部210の内面との成す角度は、45度以下であることが好ましく、本例ではこの範囲において略45度である。なお、本例の延出部261,262,263も、車両用室内灯10の延出部261,262,263と同様に、上記傾斜部分および上記平行部分の各々における車室と反対側の面に、透光導電膜251,252,253から連続する透光導電膜が形成されている。   Here, it is preferable that the angle formed by the surface opposite to the passenger compartment and the inner surface of the translucent portion 210 in the inclined portions constituting the extending portions 261, 262, and 263 is 45 degrees or less. In this range, it is approximately 45 degrees. The extended portions 261, 262, and 263 of this example are also surfaces opposite to the vehicle compartment in each of the inclined portion and the parallel portion, like the extended portions 261, 262, and 263 of the vehicle interior lamp 10. In addition, a light-transmitting conductive film continuous from the light-transmitting conductive films 251, 252, and 253 is formed.

また、図8に断面構造を示すように、延出部261,262,263の先端部には、金属プレート620がネジ留めされている。この金属プレート620の透光カバー200と反対側の先端部には、突出部622が突き出ている。そして、この突出部622は、コネクタ640と係合している。このコネクタ640は、点灯状態制御部400の回路基板410に設けられたコネクタ430と接続配線630を介して接続している。したがって、車両用室内灯13においても、透光カバー200の透光部210に形成された透光導電膜251,252,253は、延出部261,262,263の車室と反対側の面に形成された透光導電膜、金属プレート620(突出部622)、コネクタ640、接続配線630、およびコネクタ430を介して点灯状態制御部400と電気的に接続している。   Further, as shown in the cross-sectional structure in FIG. 8, a metal plate 620 is screwed to the distal ends of the extending portions 261, 262, and 263. A protruding portion 622 protrudes from a tip portion of the metal plate 620 opposite to the translucent cover 200. The projecting portion 622 is engaged with the connector 640. The connector 640 is connected to a connector 430 provided on the circuit board 410 of the lighting state control unit 400 via a connection wiring 630. Therefore, also in the vehicle interior lamp 13, the translucent conductive films 251, 252, and 253 formed on the translucent part 210 of the translucent cover 200 are the surfaces of the extending parts 261, 262, and 263 on the opposite side to the vehicle interior. Are electrically connected to the lighting state control unit 400 through the translucent conductive film, the metal plate 620 (projection 622), the connector 640, the connection wiring 630, and the connector 430.

以上に示した車両用室内灯12,13においても、上記の車両用室内灯10と同様の作用効果を奏する。すなわち、点灯状態制御部400を透光カバー200の側方に配置することで、点灯状態制御部400をオーバーヘッドコンソール1000の裏側に隠して車室内から見えないようにすることができるとともに、車両用室内灯10の車体1100(天井面)からの厚さをより小さくすることができる。また、車両用室内灯12,13では、透光カバー200の側方における様々な位置に固定されている点灯状態制御部400の回路基板410と延出部261,262,263に設けられた透光導電膜との間の電気的な接続にフレキシブルな接続配線630を用いているので、オーバーヘッドコンソール1000の裏側における回路基板410の配置の自由度が大きい。   The vehicle interior lights 12 and 13 described above also have the same effects as the vehicle interior light 10 described above. That is, by arranging the lighting state control unit 400 on the side of the translucent cover 200, the lighting state control unit 400 can be hidden behind the overhead console 1000 so that it cannot be seen from the vehicle interior. The thickness of the interior lamp 10 from the vehicle body 1100 (ceiling surface) can be further reduced. Further, in the vehicle interior lights 12 and 13, the light-transmitting portions provided on the circuit board 410 and the extending portions 261, 262, and 263 of the lighting state control unit 400 fixed at various positions on the side of the light-transmitting cover 200. Since the flexible connection wiring 630 is used for electrical connection with the photoconductive film, the degree of freedom of arrangement of the circuit board 410 on the back side of the overhead console 1000 is great.
