Description

本発明は、異なる発光色のＬＥＤ（発光ダイオード）素子が複数組み合わされたＬＥＤ光源を備え、この光源を発光させて照明をするフロアスタンド等の照明器具に関する。   The present invention relates to a lighting device such as a floor stand that includes an LED light source in which a plurality of LED (light emitting diode) elements of different light emission colors are combined and emits light from the light source.

従来、台座に付属されたフレームに直管形の蛍光ランプを垂直に配置するとともに、このランプを取巻く筒状の透光性カバーをフレームに垂直に保持した構成のフロアスタンドが知られている。このフロアスタンドでは、直管形蛍光ランプから放射される光を、筒状の透光性カバーに透過させて、フロアスタンドの周囲を照明できる（例えば、特許文献１参照。）。
特開２０００−３４０００６号公報（段落0005−0006、図１） 2. Description of the Related Art Conventionally, there has been known a floor stand having a configuration in which a straight tube fluorescent lamp is vertically arranged on a frame attached to a pedestal, and a cylindrical translucent cover surrounding the lamp is vertically held on the frame. In this floor stand, light emitted from a straight tube fluorescent lamp can be transmitted through a cylindrical translucent cover to illuminate the periphery of the floor stand (see, for example, Patent Document 1).
JP 2000-340006 (paragraphs 0005-0006, FIG. 1)

前記フロアスタンドのように光源に蛍光ランプを用いた照明器具は、蛍光ランプの寿命が尽きる度にランプ交換の必要があるばかりでなく、蛍光ランプが発する光の光色は一定である。   A lighting fixture using a fluorescent lamp as a light source such as the floor stand not only needs to be replaced every time the fluorescent lamp has reached the end of its life, but also the light color of the light emitted by the fluorescent lamp is constant.

このため、寿命が半永久的なＬＥＤを蛍光ランプに代えて光源とすることが試みられている。この場合、発光色が異なる複数のＬＥＤ素子を組み合わせて、これらのＬＥＤ素子の光を所望の割合で混ぜて照明をすることにより、白色の照明光を得るだけではなく、それ以外の色の光を得ることが可能である。白色の照明光を得るためには、赤色発光をする赤色ＬＥＤ素子と、緑色発光をする緑色ＬＥＤ素子と、青色発光をする青色ＬＥＤ素子とを組み合わせて、これらの発光色を混ぜることが一般的である。又、ＬＥＤ素子には、砲弾形のものと、表面実装形つまりＳＭＤ（Surface Mount Device）形のものがあり、後者はＬＥＤチップと称されている。指向性が極めて強い砲弾形のＬＥＤ素子は、演色性が求められる場合には、複数の発光色の混色をさせることが困難であるので、フロアスタンド等の光源としては適当ではないが、ＳＭＤ形のＬＥＤチップはその周囲に光を放射するので、フロアスタンド等の光源としての適用可能性が高いと考えられている。   For this reason, an attempt has been made to use a semi-permanent LED as a light source instead of a fluorescent lamp. In this case, by combining a plurality of LED elements having different emission colors and mixing the light of these LED elements at a desired ratio for illumination, not only white illumination light is obtained, but also light of other colors. It is possible to obtain In order to obtain white illumination light, it is common to combine red LED elements that emit red light, green LED elements that emit green light, and blue LED elements that emit blue light, and mix these emission colors. It is. Further, the LED element includes a bullet type and a surface mount type, that is, an SMD (Surface Mount Device) type, and the latter is called an LED chip. A bullet-shaped LED element with extremely strong directivity is not suitable as a light source for a floor stand or the like because it is difficult to mix a plurality of emission colors when color rendering is required. Since the LED chip emits light around it, it is considered that the LED chip is highly applicable as a light source such as a floor stand.

こうした事情から本発明者は、特にＳＭＤ形の赤色、緑色、及び青色のＬＥＤチップを、例えばこの記載順に並べて一組の発光グループとし、このグループを複数並べて直線状に配置したＬＥＤ光源を開発した。そして、このＬＥＤ光源を、前記直管形蛍光ランプと代替し、かつ、筒状の透光性カバーに向けて各ＬＥＤチップを対向配置させた構成のフロアスタンドを試作したが、以下の改善すべき課題があることが分かった。   Under these circumstances, the present inventor has developed an LED light source in which SMD red, green, and blue LED chips are arranged in the order described, for example, to form a set of light emitting groups, and a plurality of these groups are arranged in a straight line. . The LED light source was replaced with the straight tube fluorescent lamp, and a floor stand having a configuration in which each LED chip was opposed to the tubular translucent cover was prototyped. I found that there was a problem.

このフロアスタンドでは、ＬＥＤ光源の各ＬＥＤチップから放射された光が、直接透光性カバーに入射しこのカバーを透過して照明をする。ところで、ＬＥＤチップは砲弾形ＬＥＤに比較しての輝度及び指向性は弱いものの、蛍光ランプに比較すると、輝度及び指向性は強い。   In this floor stand, the light emitted from each LED chip of the LED light source is directly incident on the translucent cover and passes through the cover for illumination. By the way, although the brightness | luminance and directivity of a LED chip are weak compared with a bullet-shaped LED, a brightness | luminance and directivity are strong compared with a fluorescent lamp.

このため、透光性カバーにおいてＬＥＤ光源の光が透過する部位が視認される場合には、この透過部位のグレアが高いだけではなく、ＬＥＤ光源のイメージ、つまり、直線状に並べられた各ＬＥＤチップの発光色が色濃く前記透過部位に映る。更に、既述のように各ＬＥＤチップから透光性カバーに向けて放射された光は、そのまま直進しつつ室内の壁面等の被照明対象に到達する距離に応じて拡散されてしまう。そのため、各ＬＥＤチップの発光色が被照明対象に至るまでに十分に混ざることができず、被照明対象に色むらを生じ易いことが分かった。特に、前記発光グループのＬＥＤチップの並び方向の端に位置されたＬＥＤチップの発光色が被照明対象において目立つことが分かった。   For this reason, when the site | part through which the light of an LED light source permeate | transmits is visually recognized in a translucent cover, not only the glare of this transmission site | part is high, but the LED light source image, ie, each LED arranged in a straight line The light emission color of the chip is reflected in the transmitted part. Furthermore, as described above, the light emitted from each LED chip toward the translucent cover travels straight as it is and is diffused according to the distance reaching the object to be illuminated such as the wall surface in the room. For this reason, it has been found that the emission colors of the LED chips cannot be sufficiently mixed before reaching the object to be illuminated, and color unevenness is likely to occur in the object to be illuminated. In particular, it has been found that the light emission color of the LED chip positioned at the end of the LED chip in the light emitting group is conspicuous in the object to be illuminated.

本発明の目的は、複数のＬＥＤ素子から放射された異なる色の光が透過する投光部でのグレアを低減できるとともに、照明される被照明対象での色むらを抑制できるようにした照明器具を提供することにある。   An object of the present invention is to reduce a glare in a light projecting portion through which light of different colors radiated from a plurality of LED elements is transmitted, and to suppress uneven color in an illuminated object to be illuminated. Is to provide.

請求項１の発明は、光が透過する投光部を有した器具本体と；この器具本体の長手方向に延びる両側縁を有して断面凹形状に形成され、前記両側縁間に前記投光部を配するとともに前記投光部に対向して前記器具本体に内蔵された反射部材と；前記器具本体の長手方向に延びる光源基板上に発光部を設けて形成されるとともに、前記発光部を前記反射部材に対向させて前記反射部材と前記投光部との間に配置され、かつ、前記発光部が、発光色が異なる複数のＬＥＤ素子を有していて、これらのＬＥＤ素子が前記光源基板の長手方向に並べられているＬＥＤ光源と；を具備することを特徴としている。   The invention according to claim 1 is an instrument main body having a light projecting portion through which light is transmitted; and has both side edges extending in the longitudinal direction of the instrument main body and is formed in a concave cross section, and the light projecting between the both side edges. A reflection member built in the instrument body opposite to the light projecting part; and a light emitting part provided on a light source substrate extending in the longitudinal direction of the instrument body, and the light emitting part The light emitting unit has a plurality of LED elements having different emission colors and is disposed between the reflecting member and the light projecting unit so as to face the reflecting member, and these LED elements are the light sources. LED light sources arranged in the longitudinal direction of the substrate.

請求項１の発明は、フロアスタンドとして好適に実施できる他、ライティングレール用の照明器具、棚下灯、その他細長い器具本体を有する各種の照明器具として実施可能である。請求項１の発明で、器具本体の投光部は、器具本体の一部を占めて設けられるものであって、器具本体と一体に形成されていても、器具本体に取付けられていてもよい。これとともに、発光部から発した光が被照明対象に向けて透過する投光部は、光透過率が高く光拡散性を有していることが好ましい。このような性能を与えるために、投光部を、その光入射面又は光出射面のいずれかの面に貼着されたシート状の制光カバーを有した構成とすることができ、この場合、制光カバーにはフロスティング処理を施した透明シート又は光透過率が５０％以上の乳白色のシート等を用いることが可能である。投光部の光透過率が高いことは例えば室内の壁面等の被照明対象に投射される光量を多く確保する上で有効である。又、投光部が光拡散性を有していることは、投光部への発光部のイメージが映ることを抑制できるだけではなく、被照明対象での色むらを抑制する上で有効である。   The invention of claim 1 can be suitably implemented as a floor stand, and can be implemented as various lighting fixtures having lighting fixtures for lighting rails, shelf lamps, and other elongated fixture bodies. In the invention of claim 1, the light projecting portion of the instrument body occupies a part of the instrument body and may be formed integrally with the instrument body or attached to the instrument body. . At the same time, the light projecting unit through which the light emitted from the light emitting unit is transmitted toward the object to be illuminated preferably has high light transmittance and light diffusibility. In order to give such performance, the light projecting portion can be configured to have a sheet-like light control cover adhered to either the light incident surface or the light emitting surface. As the light control cover, a frosted transparent sheet or a milky white sheet having a light transmittance of 50% or more can be used. The high light transmittance of the light projecting unit is effective in securing a large amount of light projected onto an illumination target such as an indoor wall surface. In addition, the fact that the light projecting part has light diffusibility is effective not only in suppressing the image of the light emitting part on the light projecting part but also in suppressing color unevenness in the illumination target. .

請求項１の発明で、反射部材には、金属の地肌面でこれに入射した光を直接反射する金属製反射板や、金属又は合成樹脂の面に反射層を積層してなる反射板等を用いることができる。更に、請求項１の発明で、反射部材は投光部の長さに対応する長さを有した細長いものであって、この反射部材の断面の形状は凹形状であればよく、こうした形状として、例えば断面略コ字状でその対向する面がハ字形に開いている折れ曲がり形状、放物面等の略半円状等を挙げることができる。   In the invention of claim 1, the reflecting member includes a metallic reflector that directly reflects light incident on the metal ground surface, a reflector obtained by laminating a reflective layer on a metal or synthetic resin surface, and the like. Can be used. Further, in the invention of claim 1, the reflecting member is an elongated one having a length corresponding to the length of the light projecting portion, and the shape of the cross section of the reflecting member may be a concave shape. For example, a bent shape in which the cross-section is substantially U-shaped and the opposite surface is opened in a C shape, a substantially semicircular shape such as a paraboloid, and the like can be given.

請求項１の発明で、ＬＥＤ光源は、その発光部から発した光が投光部に直接向かう方向とは異なる方向に照射方向されるように配置することで、発光部を反射部材に対向させて設けることができる。したがって、複数のＬＥＤ光源が反射部材と投光部との間に配置される場合、反射部材又は投光部を基準として複数のＬＥＤ光源を互いに異なる角度で設けることも可能である。請求項１の発明で、複数色のＬＥＤ素子がなす一つの発光グループでの各ＬＥＤ素子の並び方は任意に選定できる。   In the invention of claim 1, the LED light source is disposed so that the light emitted from the light emitting portion is irradiated in a direction different from the direction directly toward the light projecting portion, so that the light emitting portion faces the reflecting member. Can be provided. Therefore, when a plurality of LED light sources are arranged between the reflecting member and the light projecting unit, the plurality of LED light sources can be provided at different angles with respect to the reflecting member or the light projecting unit. In the first aspect of the invention, the arrangement of the LED elements in one light emitting group formed by the LED elements of a plurality of colors can be arbitrarily selected.

請求項１の発明は、好適には、高寿命なＬＥＤ素子である赤色ＬＥＤチップ、緑色ＬＥＤチップ、及び青色ＬＥＤチップを並べてなる発光部を有したＬＥＤ光源を備えるものであり、この場合、各チップの発光量の比率を任意に変えることで、所望とする白色またはその他の光色を得て照明できる。この照明において、発光部が放射した光は、投光部を直接透過することはなく、投光部とは異なる位置にある反射部材に向けて投光され、この反射部材で投光部に向けて反射されることにより、投光部を透過して被照明対象を照明する。このように各光を反射部材で反射させることにより、光が混じり易くなって被照明対象での色むらが抑制される。更に、投光部に発光部のイメージが映ることも抑制されて、投光部でのグレアを低減できる。   The invention of claim 1 preferably includes an LED light source having a light emitting portion in which a red LED chip, a green LED chip, and a blue LED chip, which are long-life LED elements, are arranged. By arbitrarily changing the ratio of the light emission amount of the chip, a desired white or other light color can be obtained and illuminated. In this illumination, the light emitted by the light emitting unit does not directly pass through the light projecting unit, but is projected toward the reflecting member at a position different from the light projecting unit, and is directed toward the light projecting unit by this reflecting member. By being reflected, the object to be illuminated is illuminated through the light projecting unit. Thus, by reflecting each light with a reflective member, light is easy to mix and the uneven color in a to-be-illuminated object is suppressed. Furthermore, the image of the light emitting unit is prevented from being reflected on the light projecting unit, and glare at the light projecting unit can be reduced.

請求項２の発明は、前記器具本体が拡散透光性を有しているとともに、この器具本体の内面に前記反射部材の両側縁を接触させたことを特徴としている。   The invention of claim 2 is characterized in that the instrument body has diffuse translucency, and both side edges of the reflecting member are brought into contact with the inner surface of the instrument body.

この請求項２の発明で、器具本体は、その形成材料自体が拡散透光性を有するものであっても良く、或いは、透明材料に拡散透光性を与える加工、例えばフロスティング加工を施して光拡散面を与えることによって、光拡散性を得たものであってもよい。   In the invention of claim 2, the instrument body may be such that the forming material itself has a diffuse translucency, or a process for imparting a diffuse translucency to the transparent material, for example, a frosting process. Light diffusibility may be obtained by providing a light diffusion surface.

請求項２の発明では、器具本体が拡散透光性を有しているので、照明された例えば室内の壁面等の被照明対象で反射された光の一部を、器具本体に透過させて、この器具本体を光らせることができる。更に、ＬＥＤ光源の光が反射部材の側縁と器具本体の内面との間から漏れないようにしたので、発光している各ＬＥＤ素子が直線状に並んだイメージが拡散透光性器具本体の投光部の両側に映ることを抑制できる。   In the invention of claim 2, since the instrument body has diffuse translucency, a part of the light reflected by the illuminated object such as an indoor wall surface is transmitted through the instrument body, This instrument body can be illuminated. Furthermore, since the light of the LED light source is prevented from leaking between the side edge of the reflecting member and the inner surface of the instrument body, the image of the LED elements that are emitting light is arranged in a straight line. It is possible to suppress reflection on both sides of the light projecting unit.

請求項３の発明は、前記複数色のＬＥＤ素子を並べてなる発光グループと、前記各色のＬＥＤ素子の並び方向でかつ前記発光グループの両側に夫々配置された白色ＬＥＤ素子を有していることを特徴としている。   The invention of claim 3 has a light emitting group in which the LED elements of the plurality of colors are arranged, and a white LED element arranged in the direction in which the LED elements of the respective colors are arranged and on both sides of the light emitting group. It is a feature.

この請求項３の発明では、発光グループをなした複数色のＬＥＤ素子の並び方向の端に位置したＬＥＤ素子の発光色に、このＬＥＤ素子に対して並べ方向に隣接された白色ＬＥＤの白色光を混ざるので、前記並び方向の端に位置したＬＥＤ素子の発光色が目立つことを抑制できる。   According to the third aspect of the present invention, the white light of the white LED adjacent to the LED element in the arrangement direction is set to the emission color of the LED element located at the end of the arrangement direction of the plurality of color LED elements forming the light emission group. Therefore, it is possible to suppress the emission color of the LED elements positioned at the end in the arrangement direction from being noticeable.

請求項１の発明の照明器具によれば、発光色が異なる複数のＬＥＤ素子から放射された光が透過する投光部でのグレアを低減できるとともに、照明される被照明対象での色むらを抑制できる。   According to the lighting fixture of the first aspect of the invention, the glare in the light projecting portion through which the light emitted from the plurality of LED elements having different emission colors can be reduced, and color unevenness in the illumination target to be illuminated can be reduced. Can be suppressed.

請求項２の発明の照明器具によれば、器具本体を光らせることができるとともに、この器具本体の投光部の両側に、発光している各ＬＥＤ素子のイメージが映ることを抑制できる。   According to the lighting fixture of the second aspect of the invention, the fixture body can be illuminated, and the images of the light emitting LED elements can be suppressed from appearing on both sides of the light projecting portion of the fixture body.

請求項３の発明の照明器具によれば、発光グループをなす複数色のＬＥＤ素子の並び方向の端に位置されたＬＥＤ素子の発光色が目立つことを抑制して、被照明対象での色むら抑制をより促進できる。   According to the lighting fixture of the third aspect of the present invention, it is possible to suppress the emission color of the LED elements positioned at the end in the arrangement direction of the LED elements of the plurality of colors forming the light emitting group from being noticeable, and the color unevenness in the illumination target. Suppression can be further promoted.

図１〜図４を参照して本発明の第１実施形態を説明する。   A first embodiment of the present invention will be described with reference to FIGS.

図１及び図２中符号１は照明器具例えばフロアスタンドを示している。このフロアスタンド１は、台座２、器具本体５、反射部材例えば反射板１１、ＬＥＤ光源１５、及び図示しない点灯装置等を備えている。   Reference numeral 1 in FIGS. 1 and 2 denotes a lighting fixture, for example, a floor stand. The floor stand 1 includes a pedestal 2, an instrument body 5, a reflecting member such as a reflecting plate 11, an LED light source 15, and a lighting device (not shown).

台座２は例えば円形である。器具本体５は、細長い円筒形状をなしており、その下端部を台座２に連結して台座２上に起立している。この場合、図２に示すように器具本体５はその中心を台座２の中心からずらして配置されている。   The base 2 is circular, for example. The instrument body 5 has an elongated cylindrical shape, and a lower end portion of the instrument body 5 is connected to the pedestal 2 and stands on the pedestal 2. In this case, as shown in FIG. 2, the instrument body 5 is arranged with its center shifted from the center of the base 2.

器具本体５は、上下両端が開放された円筒形の筒状体６に、この筒状体６の上端開口を閉じる天板７を取付けて形成されている。筒状体６は透光性材料例えばガラスで形成されていて、その外面は、この面に微小な凹凸を作るフロスティング処理により粗面化されている。つまり、筒状体６は全体が所謂擦りガラスで作られていて、拡散透光性を有している。   The instrument body 5 is formed by attaching a top plate 7 that closes the upper end opening of the cylindrical body 6 to a cylindrical cylindrical body 6 whose upper and lower ends are open. The cylindrical body 6 is made of a translucent material such as glass, and its outer surface is roughened by a frosting process that creates minute irregularities on this surface. That is, the entire cylindrical body 6 is made of so-called frosted glass and has a diffuse translucency.

器具本体５の下部５ａの外面には例えば台座２と同色の塗料が塗られている。この塗料により器具本体５の下部５ａでは光が拡散透光することがないようにしている。器具本体５はその上部に投光部５ｂを有している。投光部５ｂは、器具本体５の周方向の一部を占めて、この器具本体５の長手方向(本実施形態では上下方向)に延びて設けられている。   For example, a paint of the same color as the base 2 is applied to the outer surface of the lower part 5 a of the instrument body 5. The paint prevents light from diffusing and transmitting in the lower part 5a of the instrument body 5. The instrument body 5 has a light projecting portion 5b at the top thereof. The light projecting portion 5b occupies a part of the circumferential direction of the instrument body 5 and is provided to extend in the longitudinal direction of the instrument body 5 (vertical direction in the present embodiment).

投光部５ｂは、後で詳述する反射板１１とともにフロアスタンド１の照明方向を規定するものである。本実施形態の場合、照射光の輝度を低減しつつ更なる光拡散性を投光部５ｂに与えるために、投光部５ｂの表面にシート状をなす透光性の制光カバー５ｃが貼付けられている。制光カバー５ｃは光透過率が５０％以上の乳白色のシート又は光拡散性のシート等からなる。   The light projecting unit 5b defines the illumination direction of the floor stand 1 together with the reflector 11 described in detail later. In the case of this embodiment, in order to give the light projecting part 5b further light diffusibility while reducing the brightness of the irradiated light, a translucent light control cover 5c that forms a sheet is attached to the surface of the light projecting part 5b. It has been. The light control cover 5c is made of a milky white sheet having a light transmittance of 50% or more, a light diffusing sheet, or the like.

図中符号８は器具本体５内に配置された柱を示している。この柱８は天板７と台座２とにわたっているとともに、図２及び図３に示すように器具本体５の中心から投光部５ｂに近付くようにずらして設けられている。   Reference numeral 8 in the drawing indicates a pillar disposed in the instrument body 5. The column 8 extends over the top plate 7 and the pedestal 2, and is shifted from the center of the instrument body 5 so as to approach the light projecting portion 5b as shown in FIGS.

反射板１１は、投光部５ｂの上下方向の長さと略同じ長さを有し、その長手方向と直交する方向の断面形状は、図２及び図３に示すように凹形状、例えば半円状をなしている。反射板１１は投光部５ｂと対向して器具本体５に内蔵されている。この反射板１１は柱８の上部に固定されている。   The reflector 11 has a length substantially the same as the length of the light projecting portion 5b in the vertical direction, and the cross-sectional shape in the direction orthogonal to the longitudinal direction is a concave shape as shown in FIGS. It has a shape. The reflector 11 is built in the instrument body 5 so as to face the light projecting portion 5b. This reflector 11 is fixed to the upper part of the column 8.

反射板１１の長手方向と直交する二つの側縁１１ａは、器具本体５の内面に好ましくは密に接触されている。なお、投光部５ｂ以外が拡散透過性を有さない構成の器具本体５としたフロアスタンドを構成する場合、反射板１１の側縁１１ａは器具本体５の内面に近接させてもよい。反射板１１の両側縁１１ａ間に投光部５ｂが位置されている。反射板１１と器具本体５の投光部５ｂとの間に筒状の光源配置スペースＳが形成されている。この光源配置スペースＳは、器具本体５の長手方向に延びていて、その上下両端はいずれも開放されている。   Two side edges 11 a orthogonal to the longitudinal direction of the reflecting plate 11 are preferably in close contact with the inner surface of the instrument body 5. In addition, when comprising the floor stand used as the instrument main body 5 of the structure other than the light projection part 5b which does not have diffuse permeability, you may make the side edge 11a of the reflecting plate 11 adjoin to the inner surface of the instrument main body 5. FIG. The light projecting portion 5 b is positioned between the side edges 11 a of the reflecting plate 11. A cylindrical light source arrangement space S is formed between the reflector 11 and the light projecting portion 5 b of the instrument body 5. The light source arrangement space S extends in the longitudinal direction of the instrument main body 5, and both upper and lower ends thereof are open.

図１〜図４に示すようにＬＥＤ光源１５は細長い一つの光源基板１６上に少なくとも一個例えば複数の発光部１７を取付けて形成されている。ＬＥＤ光源１５は、その発光部１７を反射板１１に対向させるとともに光源基板１６を投光部５ｂに対向させて光源配置スペースＳに、器具本体５の長手方向に延びて配置されている。このＬＥＤ光源１５は図示しない固定手段により反射板１１に固定されている。   As shown in FIGS. 1 to 4, the LED light source 15 is formed by attaching at least one, for example, a plurality of light-emitting portions 17 on one elongated light source substrate 16. The LED light source 15 is arranged extending in the longitudinal direction of the instrument body 5 in the light source arrangement space S with the light emitting portion 17 facing the reflecting plate 11 and the light source substrate 16 facing the light projecting portion 5b. The LED light source 15 is fixed to the reflecting plate 11 by fixing means (not shown).

図４等に示すように発光部１７は、発光部基板１８上に複数色のＬＥＤ素子、例えばＳＭＤ形ＬＥＤ（発光ダイオード）チップを複数実装して形成されている。ＬＥＤチップには、赤色発光をする赤色ＬＥＤ素子である赤色ＬＥＤチップ１９と、緑色発光をする緑色ＬＥＤ素子である緑色ＬＥＤチップ２０と、青色発光をする青色発光をする青色ＬＥＤ素子である青色ＬＥＤチップ２１が用いられている。所定の配列例えば以下の記載順序で発光部基板１８の長手方向に並べられた赤色ＬＥＤチップ１９、緑色ＬＥＤチップ２０、及び青色ＬＥＤ２１は、一つの発光グループＧを形成しており、図４に示した例では七つの発光グループＧが一つの発光部基板１８に対しその長手方向に繰り返し並ぶように実装されている。反射板１１に対向した各ＬＥＤチップは、電気的に直列に接続されていて、発光部基板１８の長手方向両端部に設けられた一対の給電端子２５，２６を介して通電される。給電端子２５，２６には図示しない点灯装置に接続された電線の端末が接続される。   As shown in FIG. 4 and the like, the light emitting unit 17 is formed by mounting a plurality of color LED elements, for example, SMD type LED (light emitting diode) chips on the light emitting unit substrate 18. The LED chip includes a red LED chip 19 that is a red LED element that emits red light, a green LED chip 20 that is a green LED element that emits green light, and a blue LED that is a blue LED element that emits blue light. A chip 21 is used. The red LED chip 19, the green LED chip 20, and the blue LED 21 arranged in a predetermined array, for example, in the longitudinal direction of the light emitting unit substrate 18 in the following description order form one light emitting group G, as shown in FIG. In this example, seven light emitting groups G are mounted on one light emitting unit substrate 18 so as to be repeatedly arranged in the longitudinal direction. The LED chips facing the reflector 11 are electrically connected in series and are energized through a pair of power supply terminals 25 and 26 provided at both ends in the longitudinal direction of the light emitting unit substrate 18. Terminals of electric wires connected to a lighting device (not shown) are connected to the power supply terminals 25 and 26.

点灯装置は、台座２又は器具本体５の下部に内蔵されるか、又はフロアスタンド１とは別置きされる。この点灯装置は、図示しないリモートコントローラによって指示された所望の点灯モードで各ＬＥＤチップを点灯させることができるようになっている。   The lighting device is built in the lower part of the pedestal 2 or the instrument main body 5 or separately from the floor stand 1. This lighting device can light each LED chip in a desired lighting mode instructed by a remote controller (not shown).

前記構成のフロアスタンド１は、その投光部５ｂを室内の壁面に対向させて使用される。このフロアスタンド１は、赤色ＬＥＤチップ１９、緑色ＬＥＤチップ２０、及び青色ＬＥＤチップ２１を繰り返し並べて直線状とした発光部１７を有するＬＥＤ光源１５を備えているので、このＬＥＤ光源１５を点灯させることによって、前記壁面つまり被照明対象を照射して室内を間接照明できる。この照明での標準の使用状態では、赤色ＬＥＤチップ１９、緑色ＬＥＤチップ２０、及び青色ＬＥＤチップ２１の発光量が所定の比率になっているので、これら三色の混合により白色光を得て照明できる。又、使用者が点灯装置を調整し各ＬＥＤチップの発光量の比率を任意に変えることで、好みに応じた他の光色を得て照明をすることができる。   The floor stand 1 having the above-described configuration is used with its light projecting portion 5b facing an indoor wall surface. Since the floor stand 1 includes the LED light source 15 having the light emitting portion 17 that is formed by repeatedly arranging the red LED chip 19, the green LED chip 20, and the blue LED chip 21, the LED light source 15 is turned on. By irradiating the wall surface, that is, the object to be illuminated, the room can be indirectly illuminated. In the standard use state in this illumination, the light emission amounts of the red LED chip 19, the green LED chip 20, and the blue LED chip 21 are in a predetermined ratio. Therefore, white light is obtained by mixing these three colors and illuminated. it can. In addition, the user can adjust the lighting device and arbitrarily change the ratio of the light emission amount of each LED chip, so that it is possible to obtain another light color according to preference and perform illumination.

以上の照明において、発光部１７の各ＬＥＤチップ１９〜２１から放射された光は、直接投光部５ｂに向かってこの投光部５ｂを透過することはなく、まず、反射板１１に向けて投光される。この場合、発光部１７から放射された光の多くはＬＥＤ光源１５を境に投光部５ｂと反対側に投光される。それ以外にもＳＭＤ形ＬＥＤチップ１９〜２１は、その側方、つまり、ＬＥＤ光源１５の幅方向（図３において左右方向）にも投光する。そして、この側方への光も投光部５ｂに直接向かうのではなく、まず、反射板１１に向けて投光され、それにより反射板１１に入射した光が、その入射角度に応じた様々な方向に反射されて、投光部５ｂを透過する。   In the above illumination, the light emitted from the LED chips 19 to 21 of the light emitting unit 17 does not directly pass through the light projecting unit 5b toward the light projecting unit 5b. Lighted. In this case, most of the light emitted from the light emitting unit 17 is projected to the opposite side of the light projecting unit 5b with the LED light source 15 as a boundary. In addition, the SMD type LED chips 19 to 21 project light on the side thereof, that is, in the width direction of the LED light source 15 (left and right direction in FIG. 3). The light to the side is not directly directed to the light projecting unit 5b, but is first projected toward the reflecting plate 11, and thus the light incident on the reflecting plate 11 varies according to the incident angle. Is reflected in the appropriate direction and passes through the light projecting portion 5b.

このように各ＬＥＤチップ１９〜２１が放射した光を反射板１１で様々な方向に反射させることにより、投光部５ｂに透過させて被照明対象である壁面を照明するので、指向性が強い各ＬＥＤチップ１９〜２１の光を容易に混ぜることができる。このため、被照明対象である室内の壁面での色むらを抑制できる。   In this way, the light emitted from each of the LED chips 19 to 21 is reflected in various directions by the reflecting plate 11 so as to be transmitted through the light projecting unit 5b and illuminate the wall surface to be illuminated. The light of each LED chip 19-21 can be easily mixed. For this reason, it is possible to suppress uneven color on the wall surface of the room that is the object to be illuminated.

しかも、本実施形態では、投光部５ｂ及びこの投光部５ｂを覆った制光カバー５ｃで、これらを通過する各色の光を拡散するので、この点においても被照明対象である室内の壁面での色むらを抑制できる。この場合、反射板１１及びＬＥＤ光源１５を器具本体５の中心よりも投光部５ｂ側に寄せて、被照明対象である室内の壁面に到達するまでの光路長を短くし、光が減衰し難くしたので、制光カバー５ｃ等による光量の低減を緩和できる。   In addition, in the present embodiment, the light projecting unit 5b and the light control cover 5c covering the light projecting unit 5b diffuse the light of each color passing therethrough. Color unevenness can be suppressed. In this case, the reflecting plate 11 and the LED light source 15 are moved closer to the light projecting unit 5b than the center of the fixture body 5 to shorten the optical path length until reaching the indoor wall surface to be illuminated, and the light is attenuated. Since it is difficult, the reduction in the amount of light by the light control cover 5c or the like can be mitigated.

更に、既述のように各ＬＥＤチップ１９〜２１が放射した光を投光部５ｂに直接透過させないとともに、光源基板１６の存在によって、発光部１７のイメージ、具体的には各ＬＥＤチップ１９〜２１によるＲ（赤色）、Ｇ（緑色）、Ｂ（青色）が繰り返して直線状に並んだ光のラインが、投光部５ｂに映ることが抑制される。このため、投光部５ｂが視認される場合にも、投光部５ｂでのグレアを低減できる。なお、投光部５ｂに対して逆側に放射されて反射板１１の幅方向中央部で反射された光の一部はＬＥＤ光源１５の特に光源基板１６で遮光されるので、その影が投光部５ｂの幅方向中央部に映る。しかし、反射板１１の幅方向両側部で反射された光の一部が投光部５ｂの幅方向中央部に差し込むので、前記影を目立たないように薄くできる。   Further, as described above, the light emitted from the LED chips 19 to 21 is not directly transmitted to the light projecting unit 5b, and the presence of the light source substrate 16 causes an image of the light emitting unit 17, specifically, each LED chip 19 to It is suppressed that the light line in which R (red), G (green), and B (blue) according to 21 are repeatedly arranged in a straight line is reflected in the light projecting unit 5b. For this reason, also when the light projection part 5b is visually recognized, the glare in the light projection part 5b can be reduced. A part of the light radiated to the opposite side with respect to the light projecting part 5b and reflected by the central part in the width direction of the reflecting plate 11 is shielded by the light source substrate 16 of the LED light source 15, and the shadow is projected. It is reflected in the central part in the width direction of the optical part 5b. However, since a part of the light reflected on both sides in the width direction of the reflecting plate 11 is inserted into the center portion in the width direction of the light projecting portion 5b, the shadow can be made thin so as not to be noticeable.

その上、各ＬＥＤチップ１９〜２１が発した光を例えば断面半円状の反射板１１で反射させて投光部５ｂに透過させることにより、各ＬＥＤチップ１９〜２１から指向性が高い光が放射されるにも拘らず、投光部５ｂを通ってこの投光部５ｂの真正面に対向した部位のみが照射されるだけではなく、被照明対象である室内の壁面を照射する光の角度が広くなるので、その周囲を含めて広範囲に照明できる。   In addition, the light emitted from the LED chips 19 to 21 is reflected by the reflecting plate 11 having a semicircular cross section, for example, and transmitted to the light projecting unit 5b, whereby light having high directivity is emitted from the LED chips 19 to 21. In spite of being emitted, not only the portion facing the front of the light projecting unit 5b through the light projecting unit 5b is irradiated, but also the angle of the light that irradiates the wall surface of the room to be illuminated. Since it becomes wider, it can be illuminated over a wide area including its surroundings.

又、器具本体５は拡散透光性を有しているので、既述のように例えば室内の壁面等に照明されて被照明対象で反射された光の一部を、器具本体５に透過させて、この器具本体５を柔らかく光らせることができる。しかも、この場合、反射板１１で反射されて投光部５ｂを通過する光の一部が、拡散透光性の投光部５ｂを一体に有した器具本体５全体に導光されるので、この点においても器具本体５を柔らかく光らせることができる。そのため、フロアスタンド１を含めてこれで照明された室内の壁面を視認する場合に、フロアスタンド１の上部が黒く視認されて、異質な感じを与えないようにできる。   Further, since the instrument body 5 has diffuse translucency, as described above, for example, a part of the light that is illuminated on the wall surface of the room and reflected by the object to be illuminated is transmitted to the instrument body 5. Thus, the instrument body 5 can be softly shone. In addition, in this case, a part of the light reflected by the reflecting plate 11 and passing through the light projecting unit 5b is guided to the entire instrument body 5 integrally having the diffuse translucent light projecting unit 5b. Also in this respect, the instrument body 5 can be softly shone. Therefore, when the indoor wall surface illuminated with this including the floor stand 1 is visually recognized, the upper part of the floor stand 1 is visually recognized as black so that an unnatural feeling is not given.

更に、反射板１１の両側縁１１ａを器具本体５の内面に接触させたので、ＬＥＤ光源１５の光が反射板１１の側縁１１ａと器具本体５の内面との間から漏れないようにできる。このため、発光部１７の発光している各ＬＥＤチップ１９〜２１のイメージ、具体的には各ＬＥＤチップ１９〜２１によるＲ（赤色）、Ｇ（緑色）、Ｂ（青色）が繰り返して直線状に並んだ光のラインが、投光部５ｂの幅方向両側に映ることを抑制できる。   Furthermore, since both side edges 11a of the reflector 11 are brought into contact with the inner surface of the instrument body 5, light from the LED light source 15 can be prevented from leaking between the side edges 11a of the reflector 11 and the inner surface of the instrument body 5. For this reason, the image of each LED chip 19-21 which the light emission part 17 is light-emitting, specifically R (red), G (green), and B (blue) by each LED chip 19-21 repeat, and it is linear. It is possible to suppress the lines of light lined up on both sides of the light projecting portion 5b in the width direction.

図５は本発明の第２実施形態を示している。第２実施形態は以下説明する事項以外は、第１実施形態と同じであるので、同じ構成については第１実施形態と同じ符号を付してその説明を省略する。   FIG. 5 shows a second embodiment of the present invention. Since the second embodiment is the same as the first embodiment except for the items described below, the same components are denoted by the same reference numerals as those of the first embodiment and description thereof is omitted.

第２実施形態は、ＬＥＤ光源１５に、白色発光をする白色ＬＥＤ素子例えばＳＭＤ形の白色ＬＥＤ２２を追加した点が第１実施形態と異なる。白色ＬＥＤ２２は、例えばＬＥＤチップとこれを封止した透光性封止材中に混ぜられた蛍光体とからなる。この白色ＬＥＤ２２で、使用するＬＥＤチップが青色ＬＥＤチップの場合には、青色光を吸収して黄色の光を放射する蛍光体が組み合わされる。同じく白色ＬＥＤ２２で、使用するＬＥＤチップが紫外光を発する紫外ＬＥＤチップの場合には、紫外光を吸収して赤色、黄色、青色の各の光を放射する三種の蛍光体が組み合わされる。   The second embodiment is different from the first embodiment in that a white LED element that emits white light, for example, an SMD type white LED 22 is added to the LED light source 15. The white LED 22 includes, for example, an LED chip and a phosphor mixed in a light-transmitting sealing material that seals the LED chip. When the white LED 22 is a blue LED chip, a phosphor that absorbs blue light and emits yellow light is combined. Similarly, in the case of the white LED 22 and the LED chip to be used is an ultraviolet LED chip that emits ultraviolet light, three types of phosphors that absorb ultraviolet light and emit red, yellow, and blue light are combined.

この白色ＬＥＤ２２は、赤色ＬＥＤチップ１９、緑色ＬＥＤチップ２０、及び青色ＬＥＤチップ２１により形成された発光グループＧの並び方向両端に隣接して夫々配置されている。なお、図５では各ＬＥＤチップの識別を容易にするために便宜上、赤色ＬＥＤチップ１９、緑色ＬＥＤチップ２０、及び青色ＬＥＤチップ２１を黒く塗って示し、白色ＬＥＤ２２は白抜きにして示した。   The white LEDs 22 are arranged adjacent to both ends of the light emitting group G formed by the red LED chip 19, the green LED chip 20, and the blue LED chip 21, respectively. In FIG. 5, for ease of identification of each LED chip, the red LED chip 19, the green LED chip 20, and the blue LED chip 21 are illustrated in black, and the white LED 22 is illustrated in white for convenience.

以上説明した事項以外は図５に示されない部分を含めて第１実施形態と同じである。したがって、第２実施形態のフロアスタンド１も、第１実施形態と同様の作用を得て、各ＬＥＤチップから放射された光が透過する投光部でのグレアを低減できるとともに、照明される被照明対象での色むらを抑制できる。   Except for the matters described above, the second embodiment is the same as the first embodiment including the portions not shown in FIG. Therefore, the floor stand 1 of the second embodiment also obtains the same operation as that of the first embodiment, can reduce glare in the light projecting part through which the light emitted from each LED chip is transmitted, and is illuminated. Color unevenness in the illumination target can be suppressed.

しかも、以上のように白色ＬＥＤ２２を設けたことにより、この白色ＬＥＤ２２に最も近い位置の赤色ＬＥＤチップ１９の赤色光又は青色ＬＥＤチップ２１の青色光に、白色ＬＥＤ２２の白色光を混ぜることができる。このため、一つの発光グループＧ１９をなしたＲＧＢの各ＬＥＤチップ１９〜２１の内で、それらの並び方向の端に位置したＬＥＤチップの光が目立たなくなるので、部屋の壁等の被照明対象での色むらの抑制をより促進できる。   Moreover, by providing the white LED 22 as described above, the white light of the white LED 22 can be mixed with the red light of the red LED chip 19 or the blue light of the blue LED chip 21 closest to the white LED 22. For this reason, among the LED chips 19 to 21 of RGB forming one light emitting group G19, the light of the LED chips located at the end in the arrangement direction becomes inconspicuous. Can further suppress uneven color.
