Description

本発明は、導光部材を用いて発光態様を得る灯具に関する。   The present invention relates to a lamp that obtains a light emission mode using a light guide member.

従来から、導光部材を用いた灯具としては、透明な樹脂やガラスの内部に光学的な障害物を作成する技術が知られている（例えば、特許文献１参照）。この特許文献１の技術は、障害物に光源からの光が反射することで光が拡散して、障害物が光源の発光色に光る。   Conventionally, as a lamp using a light guide member, a technique of creating an optical obstacle inside a transparent resin or glass is known (for example, see Patent Document 1). In the technique of Patent Document 1, light from a light source is reflected on an obstacle, so that the light is diffused and the obstacle shines in the light emission color of the light source.

また、他の導光部材を用いた灯具としては、透明な導光板の表面に掘り込みと称されるもの削孔して、この掘り込みに光源からの光を反射させる技術が知られている（例えば、特許文献２参照）。この特許文献２の技術では、掘り込みに光を反射させることで掘り込みの反対側の表面に光が出射するため、この掘り込みが光源によって発光する。
特開２００４−２４６２６０号公報 特開昭５２−１０６９７号公報 Further, as a lamp using another light guide member, a technique is known in which a so-called digging is drilled in the surface of a transparent light guide plate, and light from a light source is reflected in this digging. (For example, refer to Patent Document 2). In the technique of this patent document 2, since light is emitted to the surface on the opposite side of the digging by reflecting the light to the digging, the digging emits light by the light source.
JP 2004-246260 A JP-A 52-10697

しかしながら、上述の特許文献に係る技術を含め、従来の技術では例えば以下のような問題があった。
すなわち、従来の導光部材を用いた灯具は、光源の光が導光板全体に入射するため、本来発光させたい障害物や掘り込みには光源からの光の一部のみが入射していた。従って、従来の技術では、光源の発する光量を有効に利用できているとは言い難かった。 However, the conventional techniques including the technique related to the above-described patent document have the following problems.
That is, in the lamp using the conventional light guide member, since the light from the light source is incident on the entire light guide plate, only a part of the light from the light source is incident on an obstacle or digging that is originally intended to emit light. Therefore, it has been difficult to say that the conventional technique can effectively use the amount of light emitted by the light source.

また、従来の導光部材を用いた灯具は、灯具に備えられた一つの発光色を有する光源に応じた発光態様を得るように加工されていた。すなわち、従来の技術は、一つの灯具について一つの発光態様を得ることしかできず、一つの灯具において複数の発光色や発光態様を得られるような考慮はなされていなかった。   Moreover, the lamp using the conventional light guide member has been processed so as to obtain a light emission mode corresponding to a light source having one emission color provided in the lamp. That is, the prior art can only obtain one light emission mode for one lamp, and no consideration has been given to obtain a plurality of emission colors and light emission modes in one lamp.

本発明は、以上の問題に鑑みてなされたものである。すなわち、本発明の課題は、光源の発する光量を有効に利用可能な導光部材を用いた灯具に係る技術を提供することを目的とする。また、本発明の他の課題は、一つの灯具において複数の発光色や発光態様を得られるような導光部材を用いた灯具に係る技術を提供することを目的とする。   The present invention has been made in view of the above problems. That is, an object of the present invention is to provide a technique related to a lamp using a light guide member that can effectively use the amount of light emitted from a light source. Another object of the present invention is to provide a technique related to a lamp using a light guide member that can obtain a plurality of emission colors and emission modes in one lamp.

上記課題を解決するために、本発明は以下の手段とした。
すなわち、本発明は、平板状に形成された導光部材の平板面に平行な光を当該導光部材の外方から内方に対して入射する複数の光源と、光源からの光が導光部材の所定の領域に入射するように当該光を制御する光源制御部と、導光部材内に入射した光を入射方向とは異なる方向かつ当該導光部材の外方に光を出射する、複数の光源の一に対応する複数の発光部と、を備え、光源が発光部の一に対して光を照射し、発光部が一の光源から出射される光を平板面とほぼ垂直方向に反射する反射面を有している。 In order to solve the above problems, the present invention has the following means.
That is, according to the present invention, a plurality of light sources that inject light parallel to a flat plate surface of a light guide member formed in a flat plate shape from the outside to the inside of the light guide member, and the light from the light source guides the light. A light source control unit that controls the light so as to be incident on a predetermined region of the member, and a plurality of light beams that are emitted into the light guide member in a direction different from the incident direction and to the outside of the light guide member A plurality of light emitting units corresponding to one of the light sources, the light source irradiates light to one of the light emitting units, and the light emitting unit reflects light emitted from the one light source in a direction substantially perpendicular to the flat plate surface A reflective surface.

本発明は、光源の光を導光部材内の所定の領域に入射するために、光源近傍に光源反射部を備える。この光源反射部により、本発明は、導光部材全体に拡散することなく、光源からの光を所定の発光部に確実に入射することができる。   The present invention includes a light source reflector in the vicinity of the light source in order to make the light of the light source incident on a predetermined region in the light guide member. With this light source reflecting portion, the present invention can reliably make the light from the light source incident on the predetermined light emitting portion without diffusing to the entire light guide member.

また、本発明は、複数の光源からの光を反射して発光する発光部が、導光部材に複数設けられている。この発光部は、複数の光源に対応してその光源の一からの光を反射し発光するために、一つの光源からの光の入射角に対して所定の形状をなすように形成されている反射面を有している。この発光部により、本発明は、光源から導光部材に入射した光を導光部材内に拡散することなく出射する。また、本発明の発光部は、例えば発光色の異なる複数の光源を有する場合であっても、対応する光源からの光のみを反射面が反射する。そして、発光部は、対応する光源とは異なる他の光源からの光については、反射面の角度が当該他の光源には対応していないため、その光を発光することはない。   In the present invention, the light guide member is provided with a plurality of light emitting sections that emit light by reflecting light from a plurality of light sources. The light emitting unit is formed to have a predetermined shape with respect to an incident angle of light from one light source in order to reflect and emit light from one of the light sources corresponding to a plurality of light sources. It has a reflective surface. By this light emission part, this invention radiate | emits the light which injected into the light guide member from the light source, without diffusing in a light guide member. Moreover, even if the light emission part of this invention has a some light source from which luminescent color differs, for example, a reflective surface reflects only the light from a corresponding light source. The light emitting unit does not emit light from another light source different from the corresponding light source because the angle of the reflecting surface does not correspond to the other light source.

従って、本発明によれば、光源の発する光量を有効に利用可能な導光部材を用いた灯具に係る技術を提供することができる。また、本発明によれば、一つの灯具において複数の発光色や発光態様を得られるような導光部材を用いた灯具に係る技術を提供することができる。   Therefore, according to this invention, the technique which concerns on the lamp using the light guide member which can utilize effectively the light quantity which a light source emits can be provided. Moreover, according to this invention, the technique which concerns on the lamp using the light guide member which can obtain a some luminescent color and light emission aspect in one lamp can be provided.

また、本発明は、光源が発光ダイオードであってもよい。   In the present invention, the light source may be a light emitting diode.

また、本発明は、光源が互いに異なる発光色を有してもよい。   In the present invention, the light sources may have different emission colors.

また、本発明は、光源が、複数の発光体を有し、この複数の発光体が各々異なる発光色を有してもよい。

従って、本発明によれば、複数の光源に対応した発光部によって様々な表示態様を得ることができる。 In the present invention, the light source may include a plurality of light emitters, and the plurality of light emitters may have different emission colors.
In the present invention, different emission colors are incident on a light emitting region composed of a plurality of light emitting units corresponding to a light source from a plurality of light emitters in the light source.
Therefore, according to the present invention, various display modes can be obtained by the light emitting units corresponding to a plurality of light sources.

さらに、本発明は、光源制御部が、集光レンズ及び反射面の少なくともいずれかであってもよい。   Furthermore, in the present invention, the light source control unit may be at least one of a condenser lens and a reflecting surface.

Moreover, according to this invention, the technique which concerns on the lamp using the light guide member which can obtain a some luminescent color and light emission aspect in one lamp can be provided.

以下、図面を参照して本発明を実施するための最良の形態について説明する。以下の実施の形態の構成は例示であり、本発明は実施の形態の構成に限定されない。   The best mode for carrying out the present invention will be described below with reference to the drawings. The configuration of the following embodiment is an exemplification, and the present invention is not limited to the configuration of the embodiment.

図１は、本発明の灯具の一実施の形態である光源を発光ダイオード（LED）とした灯具１０の一例を示す図である。図１のように灯具１０は、平板状に形成されている導光部材１の側面１１Ａ〜１１Ｄの所定の位置に設けられた光源取り付け部１２Ａ〜１２Ｄに光源２Ａ〜２Ｄを備える。この光源２Ａ〜２Ｄは、異なる発光色を出射する複数のＬＥＤチップが内蔵されている。そのため、光源２Ａ〜２Ｄは、発光するＬＥＤチップを切り替えることによって、一つの光源から複数の発光色を得ることができる。   FIG. 1 is a diagram showing an example of a lamp 10 in which a light source which is an embodiment of the lamp of the present invention is a light emitting diode (LED). As shown in FIG. 1, the lamp 10 includes light sources 2A to 2D at light source mounting portions 12A to 12D provided at predetermined positions on the side surfaces 11A to 11D of the light guide member 1 formed in a flat plate shape. Each of the light sources 2A to 2D includes a plurality of LED chips that emit different emission colors. Therefore, the light sources 2A to 2D can obtain a plurality of emission colors from one light source by switching the LED chips that emit light.

また、灯具１０は、導光部材１内方の光源２Ａ〜２Ｄから発した光が到達する発光領域Ａ〜Ｄに、光源２Ａ〜２Ｄの一に対応する発光部４を発光領域ごとに所定個数（例えば図１では発光領域ごとに９個）設ける。   Further, the lamp 10 has a predetermined number of light emitting units 4 corresponding to one of the light sources 2A to 2D in the light emitting areas A to D where the light emitted from the light sources 2A to 2D inside the light guide member 1 reaches. (For example, in FIG. 1, nine are provided for each light emitting region).

次に、上述の灯具１０の各構成要素について、具体的に説明する。光源２Ａ〜２Ｄは、図１に示すように導光部材１の側面１１Ａ〜１１Ｄから導光部材１の平面部１２に平行に入射する光を照射することができるような状態で、導光部材１に取り付けられる。このとき、光源２Ａ〜２Ｄの取り付けは、既存の様々な方法（例えば接着材を用いた接着など）で行えば良い。また、光源２Ａ〜２Ｄの近傍には、光源２Ａ〜２Ｄからの光が各光源のそれぞれに対応した領域Ａ〜Ｄの発光部４に入射するようにするために、発光制御部３Ａ〜３Ｄが設けられる。この発光制御部３Ａ〜３Ｄは、光源２Ａ〜２Ｄが発した光を個々の光源２Ａ〜２Ｄに対応した発光部４に入射させるために、その光を発光領域Ａ〜Ｄ内に入光するように制御する。なお、この発光制御部３Ａ〜３Ｄには、所定の領域に光を導くことができる、例えば集光レンズや反射面などの手段を用いることが考えられる。   Next, each component of the lamp 10 will be specifically described. As shown in FIG. 1, the light sources 2 </ b> A to 2 </ b> D are capable of irradiating light incident in parallel to the planar portion 12 of the light guide member 1 from the side surfaces 11 </ b> A to 11 </ b> D of the light guide member 1. 1 is attached. At this time, the light sources 2A to 2D may be attached by various existing methods (for example, adhesion using an adhesive material). Further, in the vicinity of the light sources 2A to 2D, the light emission control units 3A to 3D are arranged so that light from the light sources 2A to 2D is incident on the light emitting units 4 in the regions A to D corresponding to the respective light sources. Provided. The light emission control units 3A to 3D enter the light into the light emitting regions A to D in order to make the light emitted from the light sources 2A to 2D enter the light emitting units 4 corresponding to the individual light sources 2A to 2D. To control. For the light emission control units 3A to 3D, it is conceivable to use means such as a condensing lens or a reflecting surface that can guide light to a predetermined area.

発光部４は、上述のように複数の光源２Ａ〜２Ｄのうち一に対応して、その光源２Ａ〜２Ｄの導光部材１内の光の入射する領域（図１における光源２Ａ〜２Ｄから発光部４へ延びる鎖線に囲まれた領域）にある発光部４の配列領域Ａ〜Ｄ内に複数設けられている。この発光部４は、例えば光源２Ａからの光が入射する領域Ａ内にあるものだけが、光源２Ａからの光によって発光する。そして、この発光部４は、発光領域Ａ以外の光源２Ｂ〜２Ｄからの光によっては発光しないように形成されている。   As described above, the light emitting unit 4 corresponds to one of the plurality of light sources 2A to 2D and emits light in the light guide member 1 of the light sources 2A to 2D (light emission from the light sources 2A to 2D in FIG. 1). A plurality of regions are provided in the array regions A to D of the light emitting unit 4 in a region surrounded by a chain line extending to the unit 4. For example, only the light emitting unit 4 in the region A where the light from the light source 2A is incident is emitted by the light from the light source 2A. And this light emission part 4 is formed so that it may not light-emit by the light from light sources 2B-2D other than the light emission area | region A. FIG.

図２及び図３は、発光部４の形状及び発光部４と光源２からの入射光との関係を簡易的に図示した平面図及び断面図の一例である。図２及び図３において、発光部４は、導光部材１の側面外方から一つの光源（不図示）による導光部材１への入射光Ｉを反射して、図２における紙面から手前に向かう方向に出射光Ｏを出射する。   FIGS. 2 and 3 are examples of a plan view and a cross-sectional view that simply illustrate the shape of the light emitting unit 4 and the relationship between the light emitting unit 4 and incident light from the light source 2. 2 and 3, the light emitting unit 4 reflects the incident light I to the light guide member 1 by one light source (not shown) from the outside of the side surface of the light guide member 1, and forwards from the paper surface in FIG. 2. Outgoing light O is emitted in the direction of heading.

図３において、導光部材１の出射光の出射方向を表面とし、その反対方向を裏面とする。発光部４は、特定の光源からの入射光Ｉのみを出射光Ｏとして導光部材１の裏面から表面に出射するために、所定の形状（入射光Ｉと出射光との関係で定められる面の方向、傾斜など）をなす反射面４１を有する。この反射面４１を導光部材１に形成するために、発光部４は、裏面側の平面から表面側へ掘られた孔部４２とからなる。本実施の形態に係る灯具１０は、このような反射面４１を有する発光部４を複数の光源２Ａ〜２Ｄのうち一の光のみを反射するように、光源２Ａ〜２Ｄと発光部４との位置を考慮して形成する。   In FIG. 3, the emission direction of the emitted light of the light guide member 1 is the front surface, and the opposite direction is the back surface. The light emitting unit 4 has a predetermined shape (a surface defined by the relationship between the incident light I and the emitted light) in order to emit only the incident light I from a specific light source as the emitted light O from the back surface to the front surface of the light guide member 1. The reflecting surface 41 has a direction, an inclination, and the like. In order to form the reflecting surface 41 on the light guide member 1, the light emitting unit 4 includes a hole 42 dug from the flat surface on the back surface side to the front surface side. In the lamp 10 according to the present embodiment, the light sources 4A to 2D and the light emitting unit 4 are configured such that the light emitting unit 4 having such a reflective surface 41 reflects only one of the light sources 2A to 2D. Form in consideration of the position.

次に、上述のような光源２Ａ〜２Ｄと発光部４とを有する導光部材１を用いた灯具１０の発光態様の一例について説明する。
図１に示した灯具１０において、光源２Ａ〜２Ｄにはそれぞれ赤、白、青、緑の発光色を有する発光体が内蔵されているとする。そして、光源２Ａが赤、光源２Ｂが白、光源２Ｃが青、光源２Ｄが緑を発光すると仮定すると、それぞれ発光領域Ａの発光部４が赤、発光領域Ｂの発光部４が白、発光領域Ｃの発光部４が青、発光領域Ｄの発光部４が緑に発光する。また、光源２Ａ〜２Ｄの発光色が変われば、それに応じてそれぞれの発光領域Ａ〜Ｄの発光部４からの発光色も変わる。このように、灯具１０は、複数の光源が各々複数の発光色を得られるようにすれば、それに応じた表示態様も、それぞれの発光部４の発光色に影響されることなく変化させることができる。 Next, an example of the light emission mode of the lamp 10 using the light guide member 1 having the light sources 2A to 2D and the light emitting unit 4 as described above will be described.
In the lamp 10 shown in FIG. 1, it is assumed that the light sources 2A to 2D each include a light emitting body having red, white, blue, and green emission colors. Assuming that the light source 2A emits red, the light source 2B emits white, the light source 2C emits blue, and the light source 2D emits green, the light emitting unit 4 in the light emitting region A is red, the light emitting unit 4 in the light emitting region B is white, and the light emitting region. The C light emitting part 4 emits blue light, and the light emitting part 4 of the light emitting area D emits green light. Moreover, if the luminescent color of light source 2A-2D changes, the luminescent color from the light emission part 4 of each light emission area | region AD will also change according to it. As described above, when the plurality of light sources can obtain a plurality of light emission colors, the lamp 10 can change the display mode corresponding to the light emission colors without being influenced by the light emission colors of the respective light emitting units 4. it can.

上述のように反射面４１の形状を形成しかつ光源２Ａ〜２Ｄと発光部４との位置を決定することによって、灯具１０は、光源の発する光量を有効に利用可能することができる。また、灯具１０によれば、一つの灯具において複数の発光色や発光態様を得ることができる。   By forming the shape of the reflection surface 41 as described above and determining the positions of the light sources 2A to 2D and the light emitting unit 4, the lamp 10 can effectively use the light amount emitted from the light source. Moreover, according to the lamp 10, a plurality of emission colors and emission modes can be obtained in one lamp.

<変形例>
本発明の灯具は、上述の実施の形態に係る灯具１０の光源と発光部との配置による発光態様に限定されず、様々な発光部の配置による発光態様を得ることができるのはいうまでもない。すなわち、本発明の灯具は、平板状の導光部材の側面から平面に平行な光を入射し、導光部材中に設けられ光源からの光を平面に向かって照射可能な反射面を有するものであればよい。 <Modification>
The lamp of the present invention is not limited to the light emission mode by the arrangement of the light source and the light emitting unit of the lamp 10 according to the above-described embodiment, and it goes without saying that the light emission mode by the arrangement of various light emitting units can be obtained. Absent. In other words, the lamp of the present invention has a reflecting surface that is incident on the flat light guide member from the side surface and is parallel to the plane, and is provided in the light guide member and can irradiate the light from the light source toward the plane. If it is.

FIG. 4 shows an example in which the light emitting units are arranged in a so-called cross (x). FIG. 5 shows an example in which the light emitting units corresponding to the light sources are arranged dispersed in the light guide member. Further, FIG. 6 is an example of a light emitting unit in which the shape of the light emitting unit is formed in a linear shape instead of a dot shape (round shape having no length) when viewed from above, unlike the above-described embodiment. Also in these modified examples, the point that the light emitting unit reflects and emits only incident light from one light source is not different from the above-described embodiment.

また、本実施の形態の灯具１０において、光源２Ａ〜２Ｄの近傍に備える入射光を制御する光源制御部を反射面によって形成したが、本発明の灯具ではこれを集光レンズによって形成しても良い。この場合、集光レンズによる光源制御部は、発光部分からの光の照射方向と拡散とを対応する発光部に入射するように形成する。   Moreover, in the lamp 10 of this Embodiment, although the light source control part which controls the incident light provided in the vicinity of the light sources 2A-2D was formed with the reflective surface, in the lamp of this invention, even if this is formed with a condensing lens. good. In this case, the light source control unit using the condenser lens is formed so that the irradiation direction and diffusion of the light from the light emitting part are incident on the corresponding light emitting part.
