Description

本発明は、車両用照明部材に関し、詳しくは、異なる発光表現が可能な車両用照明部材に関する。   The present invention relates to a vehicle lighting member, and more particularly to a vehicle lighting member capable of different light emission expressions.

近年、車両には、車外の人員に対して車両状態を認識させるための表示を照明装置（発光サインとも称する）で行うことが検討されてきている。このような発光サインとしては、車外に向けて発光するように形成されている。具体的には、発光サインは、電球やＬＥＤ等の光源と、光源の前面に配された光透過性のカバー（あるいは、レンズ）と、を備えた構成となっている。さらに、電球やＬＥＤ等の光源を複数配列して視認性を高めている。   In recent years, it has been studied on a vehicle to perform display for making a person outside the vehicle recognize the vehicle state with a lighting device (also referred to as a light emission sign). Such a light emission sign is formed to emit light to the outside of the vehicle. Specifically, the light emission sign is configured to include a light source such as a light bulb or an LED, and a light transmissive cover (or a lens) disposed in front of the light source. Furthermore, multiple light sources, such as a light bulb and LED, are arranged, and visibility is improved.

しかしながら、従来の発光サインは、光透過性のカバーに囲まれた範囲での表示（あるいは、発光表現）に限定されるという問題があった。また、発光表現についても、光源が発する光のみの単一表現に限定されていた。
本発明は上記実情に鑑みてなされたものであり、複数の発光表現が可能な車両用照明部材を提供することを課題とする。 However, there is a problem that the conventional light emission sign is limited to display (or light emission expression) in the range surrounded by the light transmissive cover. In addition, the light emission expression is also limited to a single expression of only light emitted from the light source.
This invention is made in view of the said situation, and makes it a subject to provide the illumination member for vehicles which can carry out multiple luminous expression.

上記課題を解決する本発明の車両用照明部材は、前方に発光する第１光源部と、第１光源部の前方に配された光透過性を有する光透過部材と、を有する後側発光部と、前方に発光する第２光源部と、第２光源部を収容する収容部材と、を有する、光透過部材の前方側に配された前側発光部と、前側発光部の前方側に配された光透過性を有する表皮部材と、を有することを特徴とする。
本発明の車両用照明部材は、後側発光部と前側発光部の二つの発光部を有している。この構成によると、二つの発光部を別々に発光することで、複数の発光表現が可能な車両用照明部材となる。
複数の発光表現が可能となることで、異なる複数の発光表現が可能となる。複数の発光部の発光表現に異なる意味を付与することができ、車両外部の人員に対してより多くの情報を表示できる。 A vehicular illumination member according to the present invention for solving the above-mentioned problems includes a rear light emitting portion having a first light source portion emitting light forward and a light transmitting member having a light transmitting property disposed in front of the first light source portion. And a front light emitting unit disposed on the front side of the light transmitting member, the light emitting unit including a second light source unit emitting light forward and a housing member for housing the second light source unit; And a skin member having a light transmission property.
The vehicle illumination member of the present invention has two light emitting parts, a rear side light emitting part and a front side light emitting part. According to this configuration, by separately emitting light from the two light emitting units, a vehicle lighting member capable of a plurality of light emission expressions can be obtained.
By enabling multiple light emission expressions, it is possible to perform different light emission expressions. Different meanings can be given to the light emission expressions of the plurality of light emitting units, and more information can be displayed for the personnel outside the vehicle.

The present embodiment is a vehicle lighting member 1 (hereinafter referred to as the lighting member 1) having the configuration shown in FIGS. The illumination member 1 of the present embodiment forms the outer surface of the side surface of the vehicle.
FIG. 1 is a front view showing the illumination member 1 in a state of being mounted on a vehicle. FIG. 2 is a cross-sectional view taken along line II-II in FIG.
As shown in FIG. 1, the illumination member 1 of the present embodiment is a member that forms the outer surface of the vehicle. The illumination member 1 of the present embodiment is provided on the side surface of the wheel of the vehicle.
The illumination member 1 of the present embodiment has a rear side light emitting unit 2, a front side light emitting unit 3, a skin member 4, and a control device 5 as shown in a cross sectional view in FIG. 2.

後側発光部２は、複数のＬＥＤ２０（２０Ａ〜２０Ｄ）を有する。複数のＬＥＤ２０（２０Ａ〜２０Ｄ）は、制御装置５にそれぞれ接続され、制御装置５の指示により独立して点灯（調光）・消灯が行われる。複数のＬＥＤ２０（２０Ａ〜２０Ｄ）は、前方に向けて光を発する。ＬＥＤ２０は、第１光源部に相当する。本形態ではＬＥＤを用いているが、電球等のＬＥＤ以外の光源であってもよい。本形態において、ＬＥＤ２０は、発色が単色であっても、発色光が変調可能（色調を変化可能）であっても、いずれでもよい。ＬＥＤ２０は、照明部材１の表面において発光を視認できる程度の強さの有色光を発する。   The rear side light emitting unit 2 has a plurality of LEDs 20 (20A to 20D). The plurality of LEDs 20 (20A to 20D) are connected to the control device 5, and are turned on (dimmed) and turned off independently according to an instruction of the control device 5. The plurality of LEDs 20 (20A to 20D) emit light toward the front. The LED 20 corresponds to a first light source unit. Although LEDs are used in the present embodiment, light sources other than LEDs such as light bulbs may be used. In the present embodiment, the LED 20 may be either a single color or a modulable color light (changeable color tone). The LED 20 emits colored light of such an intensity that the emitted light can be visually recognized on the surface of the illumination member 1.

ＬＥＤ２０は、基板２１に固定された状態で、収容部材２２内に収容される。基板２１は、ＬＥＤ２０を固定するとともに、ＬＥＤ２０に供給される所定の電力が流れる回路を備える。収容部材２２は、車外に面する表面側が開口した槽状を有する部材である。収容部材２２は、その内部に基板２１を収容・固定する。すなわち、収容部材２２は、基板２１（及びＬＥＤ２０）の位置を固定する。基板２１及び収容部材２２は、従来公知の構成とすることができる。   The LED 20 is housed in the housing member 22 in a state of being fixed to the substrate 21. The substrate 21 includes a circuit for fixing the LED 20 and for flowing a predetermined power supplied to the LED 20. The housing member 22 is a member having a tank shape whose surface side facing the vehicle exterior is open. The housing member 22 houses and fixes the substrate 21 therein. That is, the housing member 22 fixes the position of the substrate 21 (and the LED 20). The substrate 21 and the housing member 22 can have a conventionally known configuration.

本形態では、図２に示すように、後側発光部２の複数のＬＥＤ２０（２０Ａ〜２０Ｄ）は、前側発光部３の後方側には設けられていない。換言すると、複数のＬＥＤ２０（２０Ａ〜２０Ｄ）は、前側発光部３を投影したときに、重ならない位置に設けられている。図２では、４つのＬＥＤ２０Ａ〜２０Ｄがこの順序で基板２１上に並んだ状態で設けられている。そして、二つのＬＥＤ２０ＡとＬＥＤ２０Ｂ、ＬＥＤ２０ＣとＬＥＤ２０Ｄは近接した状態で設けられている。一方、ＬＥＤ２０ＢとＬＥＤ２０Ｃは、間隔（前側発光部３の幅より広い間隔）を隔てた状態で、設けられている。   In the present embodiment, as shown in FIG. 2, the plurality of LEDs 20 (20A to 20D) of the rear side light emitting unit 2 are not provided on the rear side of the front side light emitting unit 3. In other words, when projecting the front side light emission part 3, several LED20 (20A-20D) is provided in the position which does not overlap. In FIG. 2, four LEDs 20A to 20D are provided side by side on the substrate 21 in this order. And two LED20A, LED20B, LED20C, and LED20D are provided in the adjacent state. On the other hand, the LED 20B and the LED 20C are provided in a state of being separated by an interval (an interval wider than the width of the front side light emitting unit 3).

後側発光部２は、収容部材２２の前方側（槽状形状の開口側）に、板状（シート状）の拡散部材２３を有する。拡散部材２３は、光透過性を有する材料よりなり、光透過部材に相当する。拡散部材２３は、透明ないし半透明である部材よりなる。本形態では、その内部で光が拡散する板状（シート状）の部材である。本形態において拡散部材２３は、シリコーンやウレタン等の発泡樹脂により形成されている。   The rear side light emitting unit 2 has a plate-like (sheet-like) diffusion member 23 on the front side (opening side of the tank-like shape) of the housing member 22. The diffusion member 23 is made of a light transmitting material and corresponds to a light transmitting member. The diffusion member 23 is made of a transparent or translucent member. In this embodiment, it is a plate-like (sheet-like) member in which light is diffused. In the present embodiment, the diffusion member 23 is formed of a foamed resin such as silicone or urethane.

拡散部材２３は、複数のＬＥＤ２０を覆う。拡散部材２３は、その表面２３ａ側に、前側発光部３を収容可能な凹部２４が形成されている。凹部２４は、拡散部材２３の表面２３ａからくぼんだ有底の状態で形成されているが、拡散部材２３を厚さ方向に貫通した状態（すなわち、前側発光部３の後述する収容部材３２の裏面が収容部材２２に対向した状態）で形成されていてもよい。   The diffusion member 23 covers the plurality of LEDs 20. In the diffusion member 23, a concave portion 24 capable of accommodating the front side light emitting portion 3 is formed on the surface 23 a side. The recessed portion 24 is formed in a bottomed state recessed from the surface 23 a of the diffusion member 23, but penetrates the diffusion member 23 in the thickness direction (that is, the back surface of the housing member 32 described later of the front light emitting unit 3). May be formed in the state facing the accommodation member 22).

本形態では、拡散部材２３の表面２３ａ側に形成された凹部２４に前側発光部３を収容して設けているが、この形態に限定されない。すなわち、前側発光部３は、拡散部材２３よりも前方に配されていてもよい。この場合、前側発光部３は、拡散部材２３よりも小さい。すなわち、ＬＥＤ２０の光が拡散部材２３を透過して照明部材１から車外に照射可能に形成されている。   In the present embodiment, the front light emitting unit 3 is accommodated and provided in the recess 24 formed on the surface 23 a side of the diffusion member 23, but the present invention is not limited to this embodiment. That is, the front side light emitting unit 3 may be disposed in front of the diffusion member 23. In this case, the front side light emitting unit 3 is smaller than the diffusion member 23. That is, the light of the LED 20 is formed so as to be transmitted from the illumination member 1 to the outside of the vehicle through the diffusion member 23.

前側発光部３は、複数のＬＥＤ３０（３０Ａ〜３０Ｄ）を有する。複数のＬＥＤ３０（３０Ａ〜３０Ｄ）は、制御装置５にそれぞれ接続され、制御装置５の指示により独立して点灯（調光）・消灯が行われる。複数のＬＥＤ３０（３０Ａ〜３０Ｄ）は、前方に向けて光を発する。ＬＥＤ３０は、第２光源部に相当する。本形態ではＬＥＤを用いているが、電球等のＬＥＤ以外の光源であってもよい。本形態において、ＬＥＤ３０は、発色が単色であっても、発色光が変調可能（色調を変化可能）であっても、いずれでもよい。ＬＥＤ３０は、照明部材１の表面において発光を視認できる程度の強さの有色光を発する。   The front side light emitting unit 3 has a plurality of LEDs 30 (30A to 30D). The plurality of LEDs 30 (30A to 30D) are connected to the control device 5, and are turned on (dimmed) and turned off independently according to an instruction of the control device 5. The plurality of LEDs 30 (30A to 30D) emit light toward the front. The LED 30 corresponds to a second light source unit. Although LEDs are used in the present embodiment, light sources other than LEDs such as light bulbs may be used. In the present embodiment, the LED 30 may be either a single color or a modulable color light (changeable color tone). The LED 30 emits colored light of such an intensity that the emitted light can be visually recognized on the surface of the illumination member 1.

ＬＥＤ３０は、基板３１に固定された状態で、収容部材３２内に収容される。基板３１は、ＬＥＤ３０を固定するとともに、ＬＥＤ３０に供給される所定の電力が流れる回路を備える。収容部材３２は、車外に面する表面側が開口した槽状を有する部材である。収容部材３２は、その内部に基板３１を収容・固定する。すなわち、収容部材３２は、基板３１（及びＬＥＤ３０）の位置を固定する。基板３１及び収容部材３２は、光透過性を有していない。すなわち、基板３１及び収容部材３２は、その後方側に配された後側発光部２のＬＥＤ２０が発した光を透過せずに遮蔽する（あるいは光の透過を規制する）。基板３１及び収容部材３２は、従来公知の構成とすることができる。
表皮部材４は、前側発光部３の表面側に配されたシート状（板状）の部材である。表皮部材４は、本形態の照明部材１の表面を形成する。表皮部材４は、前側発光部３及び後側発光部２を覆うように配される。 The LED 30 is housed in the housing member 32 in a state of being fixed to the substrate 31. The substrate 31 has a circuit for fixing the LED 30 and for flowing predetermined power supplied to the LED 30. The housing member 32 is a member having a tank shape whose surface side facing the vehicle exterior is open. The accommodating member 32 accommodates and fixes the substrate 31 therein. That is, the housing member 32 fixes the position of the substrate 31 (and the LED 30). The substrate 31 and the housing member 32 do not have light transparency. That is, the substrate 31 and the housing member 32 shield the light emitted from the LED 20 of the rear side light emitting unit 2 disposed on the rear side thereof without transmitting the light (or restrict the transmission of the light). The substrate 31 and the housing member 32 can have a conventionally known configuration.
The skin member 4 is a sheet-like (plate-like) member disposed on the front surface side of the front side light emitting unit 3. The skin member 4 forms the surface of the illumination member 1 of the present embodiment. The skin member 4 is disposed to cover the front side light emitting unit 3 and the rear side light emitting unit 2.

表皮部材４は、光透過性を有する材質よりなる。表皮部材４は、透明ないし半透明である部材よりなる。本形態では、半透明のシート状（板状）の部材よりなる。本形態において表皮部材４は、シリコーンやウレタン等の発泡樹脂の薄板により形成されている。なお、表皮部材４は、織布や不織布で形成しても良い。さらに、これらの複数が積層した構成であってもよい。
表面部材４は、本形態の照明装置１において、車外に照射される光が発する表面を形成する。本形態の照明装置１では、車両の外表面を形成しており、手触りに優れることが好ましい。 The skin member 4 is made of a light transmissive material. The skin member 4 is made of a transparent or translucent member. In this embodiment, it is formed of a translucent sheet-like (plate-like) member. In the present embodiment, the skin member 4 is formed of a thin plate of a foamed resin such as silicone or urethane. The skin member 4 may be formed of a woven fabric or a non-woven fabric. Furthermore, a plurality of these may be stacked.
In the lighting device 1 of the present embodiment, the surface member 4 forms a surface from which light emitted to the outside of the vehicle is emitted. In the illuminating device 1 of this form, the outer surface of a vehicle is formed and it is preferable that it is excellent in touch.

また、表面部材４は、本形態の照明装置１において、外表面を形成するものであり、後側発光部２及び前側発光部３の全面のうちの少なくとも一部の前側の表面を被覆していればよく、前側発光部３の少なくとも一部の前側の表面を被覆していることが好ましく、前側発光部３の前側の表面の全面を被覆していることがより好ましく、照明部材１（後側発光部２と前側発光部３）の前側の表面の全面を被覆していることがさらに好ましい。   Further, in the lighting device 1 of the present embodiment, the surface member 4 forms the outer surface, and covers the front surface of at least a part of the entire surface of the rear side light emitting unit 2 and the front side light emitting unit 3. It is preferable that the front surface of at least a part of the front side light emitting portion 3 be covered, and it is more preferable that the entire front side surface of the front side light emitting portion 3 be covered; It is further preferable to cover the entire front surface of the side light emitting portion 2 and the front side light emitting portion 3).

制御装置５は、前側発光部３及び後側発光部２のそれぞれのＬＥＤ３０，２０に接続する。制御装置５は、制御部に相当する。すなわち、制御装置５は、後側発光部２のＬＥＤ２０（２０Ａ〜２０Ｃ）及び前側発光部３のＬＥＤ３０（３０Ａ〜３０Ｃ）の点灯・消灯（発光，調光）を制御する。
そして、制御装置５は、車両の乗員からの指示に基づいて、後側発光部２及び前側発光部３のそれぞれのＬＥＤ２０，３０の発光を制御する。 The control device 5 is connected to the LEDs 30 and 20 of the front side light emitting unit 3 and the rear side light emitting unit 2. The control device 5 corresponds to a control unit. That is, the control device 5 controls turning on / off (light emission, light control) of the LEDs 20 (20A to 20C) of the rear side light emitting unit 2 and the LEDs 30 (30A to 30C) of the front side light emitting unit 3.
Then, the control device 5 controls the light emission of each of the LEDs 20 and 30 of the rear side light emitting unit 2 and the front side light emitting unit 3 based on an instruction from the vehicle occupant.

照明部材１において、後側発光部２のＬＥＤ２０及び前側発光部３のＬＥＤ３０の配置は限定されない。本形態の照明部材１では、図１に示すように、後側発光部２のＬＥＤ２０は、車両のホイールの側面の全面において所定の間隔を隔てて配置されている。前側発光部３のＬＥＤ３０は、車両のホイールの形状に対応した形状をなすように略放射状に形成されている。   In the illumination member 1, the arrangement of the LEDs 20 of the rear side light emitting unit 2 and the LEDs 30 of the front side light emitting unit 3 is not limited. In the illumination member 1 of the present embodiment, as shown in FIG. 1, the LEDs 20 of the rear side light emitting unit 2 are arranged at a predetermined interval on the entire side surface of the wheel of the vehicle. The LEDs 30 of the front side light emitting unit 3 are formed substantially radially so as to have a shape corresponding to the shape of the wheel of the vehicle.

（照明部材の動作）
本形態の照明部材１の動作を、具体的に説明する。
本形態の照明部材１は、制御装置５が後側発光部２及び前側発光部３の発光を制御する。
制御装置５からの指示により後側発光部２のＬＥＤ２０（２０Ａ〜２０Ｄ）が発光する。ＬＥＤ２０が発した光は、前方側に位置する拡散部材２３に照射される。拡散部材２３に照射された光は、拡散部材２３内で拡散され、拡散部材２３の表面２３ａから拡散光として照射される。拡散部材２３の表面２３ａから拡散光として照射された光は、表皮部材４を透過し、照明部材１の表面から車外に向かって照射される。後側発光部２のＬＥＤ２０が発した光は、拡散部材２３により拡散光として照明部材１の表面から照射されており、照明部材１の表面が全面で発光したように視認される。後側発光部２のＬＥＤ２０が発した光は、図１では、破線の符号２で示した円内の全面を発光させる。 (Operation of lighting member)
The operation of the illumination member 1 of the present embodiment will be specifically described.
In the illumination member 1 of the present embodiment, the control device 5 controls the light emission of the rear side light emitting unit 2 and the front side light emitting unit 3.
In response to an instruction from the control device 5, the LEDs 20 (20A to 20D) of the rear light emitting unit 2 emit light. The light emitted from the LED 20 is emitted to the diffusion member 23 located on the front side. The light irradiated to the diffusion member 23 is diffused in the diffusion member 23 and is irradiated from the surface 23 a of the diffusion member 23 as diffused light. The light irradiated from the surface 23 a of the diffusion member 23 as diffused light passes through the skin member 4 and is irradiated from the surface of the illumination member 1 toward the outside of the vehicle. The light emitted from the LED 20 of the rear side light emitting unit 2 is irradiated from the surface of the illumination member 1 as diffused light by the diffusion member 23, and it is visually recognized as if the surface of the illumination member 1 was emitted on the entire surface. The light emitted from the LED 20 of the rear side light emitting unit 2 causes the entire surface in the circle indicated by the broken line 2 to emit light in FIG. 1.

制御装置５からの指示により前側発光部３のＬＥＤ３０（３０Ａ〜３０Ｄ）も発光する。ＬＥＤ３０が発した光は、表皮部材４に照射され、表皮部材４を透過する。そして、表皮部材４の表面から車外に向かって照射される。前側発光部３のＬＥＤ３０が発した光は、拡散部材２３を透過していないことから、拡散光ではない光として照明部材１の表面から照射される。すなわち、照明部材１の表面において、前側発光部３のＬＥＤ３０が設けられた部分の発光が視認される。前側発光部３のＬＥＤ３０が発した光は、図１では、破線の符号３で示した意匠表現を表示するように発光させる。   In response to an instruction from the control device 5, the LEDs 30 (30A to 30D) of the front light emitting unit 3 also emit light. The light emitted from the LED 30 is irradiated to the skin member 4 and passes through the skin member 4. Then, the light is irradiated from the surface of the skin member 4 to the outside of the vehicle. The light emitted from the LED 30 of the front side light emission unit 3 is not transmitted through the diffusion member 23, and therefore, is emitted from the surface of the illumination member 1 as light that is not diffused light. That is, on the surface of the illumination member 1, the light emission of the portion provided with the LED 30 of the front side light emission unit 3 is visually recognized. The light emitted from the LED 30 of the front side light emitting unit 3 is made to emit light so as to display the design expression indicated by the broken line symbol 3 in FIG. 1.

前側発光部３では、光透過性を有していない収容部材３２内にＬＥＤ３０が収容・固定されている。前側発光部３の収容部材３２が配される領域に対応した表皮部材４の領域は、後側発光部２の光が表示されなくなっている。すなわち、前側発光部３の発光のみが表示される。この構成によると、前側発光部３の発光する領域は、後側発光部２の光が遮蔽されており、前側発光部３の発光がより明瞭に（境界が明確化した状態で）表示される。   In the front side light emitting unit 3, the LED 30 is housed and fixed in the housing member 32 having no light transparency. The light of the rear side light emitting unit 2 is not displayed in the area of the skin member 4 corresponding to the area where the housing member 32 of the front side light emitting unit 3 is disposed. That is, only the light emission of the front side light emitting unit 3 is displayed. According to this configuration, the light emission area of the front side light emission unit 3 is shielded by the light of the rear side light emission unit 2 and the light emission of the front side light emission unit 3 is displayed more clearly (in the state where the boundary is clear) .

（本形態の照明部材の効果）
本形態の照明部材１は、図１〜２に示すように、後側発光部２、前側発光部３、表皮部材４を有する。後側発光部２は、ＬＥＤ２０と、その前方に配された光透過性を有する拡散部材２３と、を有する。前側発光部３は、ＬＥＤ３０と、ＬＥＤ３０を収容する収容部材３２と、を有する、拡散部材２３の前方側に配される。表皮部材４は、前側発光部３の前方側に配され、光透過性を有する。 (Effect of the illumination member of the present embodiment)
As shown in FIGS. 1 and 2, the illumination member 1 of the present embodiment has a rear side light emitting unit 2, a front side light emitting unit 3, and a skin member 4. The back side light emission part 2 has LED20 and the spreading | diffusion member 23 which has light transmittance arranged in the front. The front side light emitting unit 3 is disposed on the front side of the diffusion member 23 including the LED 30 and the housing member 32 for housing the LED 30. The skin member 4 is disposed on the front side of the front side light emitting unit 3 and has light transparency.

本形態の照明部材１は、後側発光部２と前側発光部３の二つの発光部（すなわち、異なる二つの発光部２，３のＬＥＤ２０，３０）を有している。この構成によると、二つの発光部２，３のＬＥＤ２０，３０を別々に発光することが可能となっている。すなわち、異なる複数の発光表現が可能な車両用照明部材１となっている。   The illumination member 1 of the present embodiment has two light emitting parts of the rear side light emitting part 2 and the front light emitting part 3 (that is, LEDs 20 and 30 of two different light emitting parts 2 and 3). According to this configuration, the LEDs 20 and 30 of the two light emitting units 2 and 3 can emit light separately. That is, the vehicle illumination member 1 is capable of different light emission expressions.

また、本形態の照明部材１は、二つの発光部２，３が異なる複数の発光表現が可能となっている。この構成によると、二つの発光部２，３の発光表現に異なる意味を付与することができ、車両外部に対してより多くの情報を表示できる。
例えば、前側発光部３のＬＥＤ３０は、ホイールに合わせて配置されており、ホイールの回転に合わせた発光表現を行うことができる。すなわち、車両が走行していることを表現させることができる。 Further, in the illumination member 1 of the present embodiment, a plurality of light emission expressions in which the two light emitting portions 2 and 3 are different are possible. According to this configuration, the light emission expressions of the two light emitting units 2 and 3 can be given different meanings, and more information can be displayed outside the vehicle.
For example, the LEDs 30 of the front side light emitting unit 3 are arranged in accordance with the wheel, and can perform light emission expression in accordance with the rotation of the wheel. That is, it can be expressed that the vehicle is traveling.

一方、後側発光部２のＬＥＤ２０は、ホイールの側面の全面を発光（面発光）する。後側発光部２のＬＥＤ２０は、車両の状態を表示させることができる。例えば、車両が前進しているとき、あるいは後進（後退）しているときに、所定の光を発するように設定することができる。さらに、自動運転車においては、手動運転モードと自動運転モードのそれぞれにおいて、後側発光部２のＬＥＤ２０が異なる発光をするように設定することができる。   On the other hand, the LED 20 of the rear side light emitting unit 2 emits light (surface light emission) on the entire side surface of the wheel. The LED 20 of the rear side light emitting unit 2 can display the state of the vehicle. For example, it can be set to emit a predetermined light when the vehicle is moving forward or backward. Furthermore, in an automatic driving vehicle, the LED 20 of the rear side light emitting unit 2 can be set to emit different light in each of the manual operation mode and the automatic operation mode.

本形態の照明部材１は、前側発光部３の収容部材３２が、後側発光部２のＬＥＤ２０が発する光を遮蔽する。この構成によると、前側発光部３の発光が表示される表皮部材４の領域では、後側発光部２の光が表示されなくなり、前側発光部３の発光のみが表示される。この構成によると、後側発光部２の発光面と、前側発光部３の発光との境界が明確化し、複数の発光表現がより明確に視認できるようになる。   In the illumination member 1 of the present embodiment, the housing member 32 of the front side light emitting unit 3 shields the light emitted by the LED 20 of the rear side light emitting unit 2. According to this configuration, in the region of the skin member 4 in which the light emission of the front side light emitting unit 3 is displayed, the light of the rear side light emitting unit 2 is not displayed, and only the light emission of the front side light emitting unit 3 is displayed. According to this configuration, the boundary between the light emitting surface of the rear side light emitting unit 2 and the light emission of the front side light emitting unit 3 is clarified, and a plurality of light emission expressions can be more clearly viewed.

本形態の照明部材１は、後側発光部２のＬＥＤ２０が前側発光部３と重ならない位置に設けられている。前側発光部３の収容部材３２が光透過性を有していないため、後側発光部２のＬＥＤ２０が前側発光部３と重なる位置に設けられていても、当該ＬＥＤの光は、照明部材１から照射されにくい。このため、不要なＬＥＤ２０を配することによるコストの増加が抑えられる。   The illumination member 1 of the present embodiment is provided at a position where the LEDs 20 of the rear side light emitting unit 2 do not overlap with the front side light emitting unit 3. Since the housing member 32 of the front side light emitting unit 3 does not have light transparency, even if the LED 20 of the rear side light emitting unit 2 is provided at a position overlapping with the front side light emitting unit 3, the light of the LED is the illumination member 1. It is hard to be irradiated from For this reason, the increase in the cost by arrange | positioning unnecessary LED20 is suppressed.

本形態の照明部材１は、後側発光部２が、ＬＥＤ２０の前方に拡散部材２３を配している。この構成によると、拡散部材２３がＬＥＤ２０の光を拡散することで、後側発光部２の発する光が面発光となる。この結果、前側発光部３の発する光と異なる発光形態の光を発することができ、より視認性に優れた光を発することができる。   In the illumination member 1 of the present embodiment, the rear side light emitting unit 2 has a diffusion member 23 disposed in front of the LED 20. According to this configuration, the diffusion member 23 diffuses the light of the LED 20, whereby the light emitted by the rear side light emitting unit 2 becomes surface light emission. As a result, it is possible to emit light of a light emission form different from the light emitted by the front side light emitting unit 3, and it is possible to emit light more excellent in visibility.

本形態の照明部材１は、後側発光部２のＬＥＤ２０及び前側発光部３のＬＥＤ３０に接続する制御装置５を有する。この構成によると、制御装置５が二つの発光部２，３のＬＥＤ２０，３０の発光を制御できる。この結果、本形態の照明部材１は、異なる発光パターンで発光することができる。   The illumination member 1 of the present embodiment includes the control device 5 connected to the LED 20 of the rear side light emitting unit 2 and the LED 30 of the front side light emitting unit 3. According to this configuration, the control device 5 can control the light emission of the LEDs 20 and 30 of the two light emitting units 2 and 3. As a result, the illumination member 1 of the present embodiment can emit light with different light emission patterns.
