【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】本発明は公園あるいは駅前広場等で使用する照明器具の改良に関する。 The present invention relates to an improvement of lighting equipment to be used in the park or in front of the station square and the like.

【0002】 [0002]

【従来の技術】従来、公園あるいは駅前広場等で使用する照明器具は、照明器具の設置場所の条件により、広角の配光を有する照明器具、中角の配光を有する照明器具、狭角の配光を有する照明器具を任意に選択し使用することが実施されている。 Conventionally, lighting equipment to be used in the park or station square, etc., depending on the conditions of the installation location of the luminaire, a luminaire having a wide angle of light distribution, the luminaire having a light distribution of the medium angle, the narrow angle It is arbitrarily selected by using the luminaire comprising a light distribution is performed. ところで、従来照明器具の配光を例えば広角、中角、狭角に変えるには、複数の反射鏡を用意し、所望の配光に合わせて反射鏡を取り付けることが実施されている。 Incidentally, the light distribution, for example, wide-angle conventional luminaire, medium angle, the change in narrow angle, by preparing a plurality of reflecting mirrors, and is implemented to attach the reflector to match the desired light distribution. また他の配光を制御する構造としては、反射鏡は固定しておき、光源の位置を可変し配光を制御する構造が実施されている。 As the structure for controlling the other light distribution, the reflecting mirror is previously fixed, variable and structure for controlling the light distribution is being carried out the position of the light source.

【0003】 [0003]

【発明が解決しようとする課題】ところで上記した複数の反射鏡を用意し、配光により選択し取り付ける構造によると、複数の形状の反射鏡を用意する必要があり、また一度反射鏡を照明器具本体に固定すると、他の配光の反射鏡と交換するのに手数を要する欠点がある。 Providing a plurality of reflecting mirrors which way the above-mentioned [0008], according to the selected mounting structure by light distribution, it is necessary to prepare a reflector of a plurality of shapes, also once illuminating the reflector device When secured to the body, there is a drawback that requires labor to replace the reflector other light distribution. また反射鏡を固定しておき、光源の位置を可変する構造によると、任意の配光に調整することが難しく、配光の制御に限界がある欠点がある。 The reflectors leave fixed, according to the position of the light source to the variable structures, it is difficult to adjust to any light distribution, there is a drawback that there is a limit to the control of the light distribution. さらに左右非対称の配光を得るには専用の反射体を用意しなければならない欠点がある。 Furthermore in order to obtain a light distribution asymmetrical has the drawback that must be provided a dedicated reflector.

【0004】本発明は上記の点に鑑み発明したものであって、一台の照明器具で複数種の配光を容易に得ることができ照明器具を提供することを目的とする。 [0004] The present invention was invented in view of the above problems, and an object thereof is to provide a luminaire can be obtained a plurality of types of light distribution easily by a single luminaire.

【0005】 [0005]

【課題を解決するための手段】本発明は上記課題を解決するために次の構成とする。 SUMMARY OF THE INVENTION The present invention has the following configuration to solve the above problems. つまり、内部に光源を配置してなる照明器具本体の前面に、中央付近を拡散面に構成し、且つ拡散面の外周を透明に構成してなる透光板を配置する。 That is, the front of the luminaire main body formed by placing a light source therein, the vicinity of the center constitute the diffusing surface, and the outer periphery of the diffusing surface to place the transparent structure to become transparent plate. また光源の長手方向の両側に、角度調整自在に構成してなる反射鏡を配置する。 Also on both sides in the longitudinal direction of the light source, arranging the angle adjustable becomes configured reflector. そして反射鏡の一方もしくは両方の角度を調整し、複数の配光を得るように構成してある。 And one or both of the angle of the reflecting mirror to adjust, and are configured to obtain a plurality of light distribution.

【0006】 [0006]

【作用】上記構造の照明器具によると、両側の反射鏡を同一の角度に設定するか、あるいは両側の反射鏡を角度を変えて設定することにより、多種の照明を得ることができる。 According to the luminaire of the effects above structure, set on either side of the reflector at the same angle, or by both sides of the reflecting mirror set at different angles, it is possible to obtain an illumination of a wide.

【0007】 [0007]

【実施例】以下本発明を図1ないし図6について説明する。 EXAMPLES Hereinafter the present invention will FIGS. 1 to 6 will be described. 図において、1は下面を開口してなる照明器具本体、2は照明器具本体1の内部に固定してなるソケット、3はソケット2に装着してなる光源であって、例えば100ワット程度の高圧放電ランプ、4は照明器具本体1の内部に固定してなる支持具、5は支持具4に左右対称に配置してなる反射鏡支持具、6は反射鏡支持具5 In the figure, the luminaire main body 1 is formed by opening the lower surface, the socket 2 is formed of a fixed inside the luminaire main body 1, 3 is a light source formed by mounting the socket 2, for example, about 100 watts high pressure discharge lamps, 4 support formed of a fixed inside the luminaire body 1, 5 reflector support formed by arranging symmetrically to the bracket 4, 6 reflector support 5
に角度を可変し得るように配置してなる角度調整具であって、広角、中角、狭角に角度を可変し得るように複数の位置決め溝7、8を設けて構成してある。 The angle an angle adjuster formed by arranging As can be variably, wide, medium angle, are configured by providing a plurality of positioning grooves 7 and 8 so as to vary the angle to a narrow angle. 9は角度調整具6に支持してなる反射鏡であって、光源の長手方向を中心に左右対称に配置して構成してある。 9 is a reflecting mirror formed by supporting the angle adjustment device 6, are constituted by symmetrically arranged about the longitudinal direction of the light source.

【0008】10は図3に示すように、照明器具本体1 [0008] 10, as shown in FIG. 3, the luminaire body 1
の下面開口部に支持してなる平板状の透光板であって、 A plate-like transparent plate formed by supporting on the lower surface opening,
例えばアクリルで構成してある。 For example, it is composed of acrylic. また同透光板は図3に示すように、中央付近を拡散面11に構成し、且つ拡散面の外周を透明12に構成してある。 The DoToruhikariban, as shown in FIG. 3, the vicinity of the center constitute the diffusing surface 11, are and the outer periphery of the diffusing surface is configured to clear 12. 拡散面11はいわゆるフロスト処理あるいは印刷で凹凸に構成する。 Diffusing surface 11 constitutes the irregularities in the so-called frosting or printing. また拡散面11と透明部12は例えば1対1の割合で構成する。 The diffusion surface 11 and the transparent portion 12 is constituted by a rate of for example 1: 1. 透光板10の拡散面11と透明部12と反射鏡9 Diffusing surface 11 and the transparent portion 12 and the reflecting mirror of the transparent plate 10 9
は、反射光を考慮し、広角配光におては、反射光が全て拡散面11に入り、狭角配光においては、反射光が拡散面に全く入らず透明部12のみに入るように構成してある。 It considers the reflected light, is your wide-angle light distribution, all reflected light enters the diffusion surface 11, in the narrow-angle light distribution, as reflected light enters only the transparent part 12 not completely enter the diffusion surface configure and Aru.

【0009】次に上記構造の照明器具における配光の制御を図5と図6について説明する。 [0009] Next will be described the control of the light distribution in the luminaire of the structure for Figures 5 and 6. 図5は反射鏡を最大限閉じた状態を示し、反射光と直射光は全て拡散面11 Figure 5 shows a closed maximum reflecting mirror, all direct light and the reflected light diffusing surface 11
に入り、広角照明ができる。 To enter, it is a wide-angle illumination. また反射光と直射光は全て拡散面11を通って、照射されるので、被照射面での均斉度は上り、またグレアーは軽減される。 Also through all direct light and the reflected light diffusing surface 11, because it is irradiated, uniformity in the illuminated surface is up, also glare is reduced.

【0010】図6は反射鏡を最大限開いた状態を示し、 [0010] Figure 6 shows an opened state maximize reflector,
光源の直下方向の照射光は、拡散面11を通って照射されるので、被照射面での均斉度は上り、また反射光の一部は透明部12を通って照射されるので、狭い被照射面を立体的に照明することができる。 Irradiating light directly under the direction of the light source, because it is irradiated through the diffusion surface 11, uniformity in the illuminated surface is up, and because part of the reflected light is irradiated through the transparent portion 12, a narrow target it can stereoscopically illuminate the irradiated surface. 図5ないし図6の間で反射鏡の角度を設定してもよい。 It may be set the angle of the reflecting mirror between the FIGS. 5-6.

【0011】また光源の両端に配置した反射鏡の角度を各々変えて構成設定することにより、非対称の配光を得ることもできる。 [0011] By constituting set by changing each the angle of a reflecting mirror disposed at both ends of the light source can be obtained a light distribution asymmetric.

【0012】 [0012]

【発明の効果】本発明は上記のように、光源の前面に、 According to the present invention as described above, the front of the light source,
中央付近を拡散面に構成し、外周を透明に構成した透光板を配置して構成し、また光源の長手方向の両側に、角度調整自在に構成してなる反射鏡を配置して構成したので、反射鏡の角度を調整することにより、多種の照明を容易に得ることができる特有な効果を有する。 The vicinity of the center constitute the diffusing surface, constituted by arranging a transparent structure and translucent plate periphery and on both sides of the longitudinal direction of the light source was constructed by placing the angle adjustable becomes configured reflector since, by adjusting the angle of the reflecting mirror has a unique advantage of being able to easily obtain the illumination wide.
