Description

本発明は、照明器具に関するものである。   The present invention relates to a lighting fixture.

LEDを光源とする照明器具は、数多く提供されている(例えば、特許文献1参照)。   Many lighting fixtures using LEDs as light sources are provided (see, for example, Patent Document 1).

特開2009−181813号公報JP 2009-181813 A 米国特許第3549879号明細書US Pat. No. 3,549,879

LEDを光源とする照明器具では、LED発光部は輝度が高く、まぶしく見える。一方、LEDは指向性が強いため、例えば天井等の器具設置面に対し垂直方向を照射する直付型照明器具では、LEDから照射された光が照明器具の側面や器具設置面に当たらず暗く見える。LED発光部と直付型照明器具の側面や器具設置面が同時に視野に入る場合、これらの輝度比が大きく、グレアを感じるという課題があった。   In a luminaire using an LED as a light source, the LED light-emitting portion has high brightness and looks dazzling. On the other hand, since LED has high directivity, for example, in a direct-mounted lighting fixture that irradiates a vertical direction with respect to a fixture installation surface such as a ceiling, the light emitted from the LED does not hit the side or fixture installation surface of the lighting fixture and is dark appear. When the LED light emitting unit and the side surface of the direct-mounted illumination device or the device installation surface are in the field of view at the same time, there is a problem that these luminance ratios are large and glare is felt.

本発明は、例えば、照明器具の光源部分と天井等の器具設置面との輝度比を小さくすることを目的とする。   An object of the present invention is, for example, to reduce the luminance ratio between a light source portion of a lighting fixture and a fixture installation surface such as a ceiling.

本発明の一の態様に係る照明器具は、
天井の器具設置面に取り付けられる照明器具であり、
前記器具設置面に取り付けられる取付面と、前記取付面に平行な底面と、前記取付面から前記底面にわたって存在し、前記取付面から前記底面に向かって少なくとも一部が内側に傾斜する傾斜側面とを有する器具本体と、
前記器具本体の取付面に対して垂直方向に光を放射する光源と、
前記器具本体の底面から前記器具本体の外側に膨らみ、前記光源から放射される光を拡散させるカバーであって、断面形状が湾曲部分を含み、当該湾曲部分によって前記光源から放射される光の一部を拡散させて前記器具本体の傾斜側面に到達させるカバーとを備える。
A lighting apparatus according to one aspect of the present invention includes:
It is a lighting fixture attached to the fixture installation surface of the ceiling,
An attachment surface attached to the appliance installation surface; a bottom surface parallel to the attachment surface; an inclined side surface that exists from the attachment surface to the bottom surface, and that is inclined at least partially inward from the attachment surface toward the bottom surface; An instrument body having:
A light source that emits light in a direction perpendicular to the mounting surface of the instrument body;
A cover that swells from the bottom surface of the instrument body to the outside of the instrument body and diffuses light emitted from the light source, the cross-sectional shape including a curved part, and one of the light emitted from the light source by the curved part. And a cover that diffuses the part to reach the inclined side surface of the instrument body.

本発明によれば、断面形状が湾曲部分を含むカバーが、当該湾曲部分によって光源から放射される光の一部を拡散させて器具本体の傾斜側面に到達させるため、光源から放射される光が器具本体の傾斜側面に当たり、また、その光がさらに天井等の器具設置面に当たることにより、照明器具の光源部分と器具設置面との輝度比が小さくなる。   According to the present invention, the cover whose cross-sectional shape includes the curved portion diffuses a part of the light emitted from the light source by the curved portion and reaches the inclined side surface of the instrument body. When the light strikes the inclined side surface of the fixture body and the light further strikes the fixture installation surface such as the ceiling, the luminance ratio between the light source portion of the lighting fixture and the fixture installation surface becomes small.

以下、本発明の実施の形態について、図を用いて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

実施の形態1.
図1は、本実施の形態に係る照明器具10の斜視図である。図2は、照明器具10の側面図(左上)、平面図(右上)、正面図(右下)である。図3は、照明器具10の分解斜視図である。図4は、照明器具10の設置状態の側面図である。
Embodiment 1 FIG.
FIG. 1 is a perspective view of a lighting fixture 10 according to the present embodiment. FIG. 2 is a side view (upper left), a plan view (upper right), and a front view (lower right) of the luminaire 10. FIG. 3 is an exploded perspective view of the lighting fixture 10. FIG. 4 is a side view of the installation state of the lighting fixture 10.

本実施の形態において、照明器具10は、天井等の器具設置面20(図4参照)に取り付けられるものである。照明器具10は、光を放射する光源としてLED11を複数備えるほか、LED11を収容する器具本体12、及び、光を拡散させるカバー13を備える。   In this Embodiment, the lighting fixture 10 is attached to fixture installation surfaces 20 (refer FIG. 4), such as a ceiling. The lighting fixture 10 includes a plurality of LEDs 11 as a light source that emits light, and also includes a fixture body 12 that houses the LEDs 11 and a cover 13 that diffuses light.

図2右上の平面図(右半分はカバー13を取り付けた状態、左半分はカバー13を取り外した状態である)に示すように、本実施の形態において、LED11は、器具本体12の内側に略直線状に配列されている。なお、LED11は、他の形状をなすように配列されていてもよい。例えば器具本体12を平面視円形状に形成して、その器具本体12の内側にLED11をリング状に配置してもよい。また、例えばLED11をランダムに配置してもよい。   As shown in the plan view on the upper right of FIG. 2 (the right half is a state where the cover 13 is attached, and the left half is a state where the cover 13 is removed), in the present embodiment, the LED 11 is substantially inside the instrument body 12. They are arranged in a straight line. In addition, LED11 may be arranged so that another shape may be made. For example, the instrument body 12 may be formed in a circular shape in plan view, and the LEDs 11 may be arranged in a ring shape inside the instrument body 12. For example, you may arrange | position LED11 at random.

器具本体12は、器具設置面20に取り付けられる取付面21と、LED11から放射される光を出射する出射面22と、取付面21から出射面22に向かって少なくとも一部が内側に傾斜する傾斜側面23とを有する。図4に示すように、本実施の形態において、取付面21、出射面22、LED11が取り付けられる面は、互いに平行であるが、必ずしも平行でなくてよい。また、傾斜側面23は、上部が略垂直な面になっているが、他の部分と同様に傾斜していてもよい。即ち、傾斜側面23は、全体が内側に傾斜していてもよい(器具設置面20に対する傾斜角は、0°より大きく90°より小さければよく、例えば60°等となる)。また、傾斜側面23は、LED11の配列方向に沿って延在しているが、LED11の配列方向と直交する方向に沿って延在していてもよい。即ち、傾斜側面23は、器具本体12の長手方向及び短手方向のどちらにあってもよく、両方向に存在していてもよい。   The instrument main body 12 has an attachment surface 21 attached to the instrument installation surface 20, an emission surface 22 that emits light emitted from the LED 11, and an inclination that at least a part is inclined inward from the attachment surface 21 toward the emission surface 22. And a side surface 23. As shown in FIG. 4, in the present embodiment, the attachment surface 21, the emission surface 22, and the surface to which the LED 11 is attached are parallel to each other, but are not necessarily parallel. In addition, the inclined side surface 23 has a substantially vertical upper portion, but may be inclined in the same manner as other portions. That is, the entire inclined side surface 23 may be inclined inward (the inclination angle with respect to the device installation surface 20 may be larger than 0 ° and smaller than 90 °, for example, 60 °). Further, the inclined side surface 23 extends along the arrangement direction of the LEDs 11, but may extend along a direction orthogonal to the arrangement direction of the LEDs 11. That is, the inclined side surface 23 may be in either the longitudinal direction or the short direction of the instrument main body 12 and may exist in both directions.

器具本体12の内側には、LED11から放射される光を反射するリフレクタ14が複数設けられており、各リフレクタ14はLED11と1対1で対応している。各リフレクタ14の出光側開口部は、器具本体12の出射面22を形成している。なお、リフレクタ14は、1つが複数のLED11に対応するように設けられていてもよい。図示しないが、器具本体12の内側には、さらに、LED11に電力を供給する電源装置や、電源端子台等の電装部品が実装される。   A plurality of reflectors 14 that reflect light emitted from the LEDs 11 are provided inside the instrument body 12, and each reflector 14 has a one-to-one correspondence with the LEDs 11. The light exit side opening of each reflector 14 forms an exit surface 22 of the instrument body 12. In addition, the reflector 14 may be provided so that one may respond | correspond to several LED11. Although not shown, a power supply device that supplies power to the LED 11 and electrical components such as a power supply terminal block are further mounted inside the instrument body 12.

例えば、器具本体12は、板金を折り曲げあるいは組み合わせて、側面形状が略台形状をなす直方体に形成される。本実施の形態では、図4に示すように、器具本体12の断面形状が、上底部分を出射面22とし、下底部分を取付面21とし、左右両側の斜辺部分を傾斜側面23とする略台形状になっている。   For example, the instrument main body 12 is formed into a rectangular parallelepiped having a substantially trapezoidal side surface by bending or combining sheet metals. In the present embodiment, as shown in FIG. 4, the cross-sectional shape of the instrument body 12 is such that the upper bottom portion is the emission surface 22, the lower bottom portion is the mounting surface 21, and the oblique sides on both the left and right sides are the inclined side surfaces 23. It has a substantially trapezoidal shape.

カバー13は、器具本体12の出射面22を覆うように設置され、出射面22から出射される光を拡散させる。カバー13は、器具本体12の傾斜側面23の上記少なくとも一部(内側に傾斜している部分)の延長面24(LED11が取り付けられた面から広がる傾斜面からなる側面外形面)よりも外側(器具外)に突出する凸部31(図4の斜線部)を有する。本実施の形態では、器具本体12の傾斜側面23がLED11の配列方向に沿って延在しているため、カバー13の凸部31は、LED11の配列方向と直交する方向に向かって外側に突出している。   The cover 13 is installed so as to cover the emission surface 22 of the instrument body 12 and diffuses light emitted from the emission surface 22. The cover 13 is outside the extended surface 24 (side surface outer surface composed of an inclined surface extending from the surface to which the LED 11 is attached) of at least a part (the portion inclined inward) of the inclined side surface 23 of the instrument body 12 ( It has the convex part 31 (shaded part of FIG. 4) which protrudes out of an instrument. In the present embodiment, since the inclined side surface 23 of the instrument main body 12 extends along the arrangement direction of the LEDs 11, the convex portion 31 of the cover 13 protrudes outward in a direction orthogonal to the arrangement direction of the LEDs 11. ing.

例えば、カバー13は、側断面形状が略蒲鉾形状をなしており、器具本体12に取り付けられる複数のLED11の前面に取り付けられる。本実施の形態では、図4に示すように、カバー13の断面形状が、湾曲部分を凸部31の外表面の少なくとも一部とする略蒲鉾状になっている。   For example, the cover 13 has a substantially bowl-shaped side cross-sectional shape, and is attached to the front surface of the plurality of LEDs 11 attached to the instrument body 12. In the present embodiment, as shown in FIG. 4, the cross-sectional shape of the cover 13 is substantially bowl-shaped with the curved portion as at least a part of the outer surface of the convex portion 31.

例えば、カバー13は、乳白アクリル等の拡散透光性を有する合成樹脂材料で形成される。カバー13は、内外表面が細かく凹凸加工されており、例えば透過率が70%の場合、導光及び乱反射する光は約30%である。   For example, the cover 13 is formed of a synthetic resin material having diffuse translucency such as milky white acrylic. The cover 13 has fine irregularities on the inner and outer surfaces. For example, when the transmittance is 70%, light that is guided and diffusely reflected is about 30%.

本実施の形態では、光源として、器具本体12の取付面21に対して略垂直方向に光を放射するLED11を用いているが、カバー13に、器具本体12の傾斜側面23の延長面24よりも外側に突出する凸部31を設けているため、LED11から放射される光が器具本体12の傾斜側面23にも当たる。また、器具本体12の傾斜側面23に当たって反射した光がさらに器具設置面20にも当たる。これにより、照明器具10の光源部分と器具設置面20との輝度比が小さくなる。   In the present embodiment, the LED 11 that emits light in a direction substantially perpendicular to the mounting surface 21 of the instrument main body 12 is used as the light source, but the cover 13 has an extension surface 24 of the inclined side surface 23 of the instrument main body 12. Since the convex portion 31 protruding outward is also provided, the light emitted from the LED 11 also strikes the inclined side surface 23 of the instrument body 12. Further, the light reflected by the inclined side surface 23 of the instrument body 12 further strikes the instrument installation surface 20. Thereby, the luminance ratio of the light source part of the lighting fixture 10 and the fixture installation surface 20 becomes small.

図5は、照明器具10の側面図であり、カバー13からの拡散光を図示したものである。   FIG. 5 is a side view of the luminaire 10 and illustrates diffused light from the cover 13.

図5に示すように、カバー13は、LED11の前面(発光面)を覆うように器具本体12に取り付けられるので、LED11が発する光が直接看者の視野に入らず、輝度が低減される。また、LED11から放射された光の一部は、カバー13の板厚内を導光したり、カバー13内部で乱反射したりした後に、凸部31で拡散し、器具本体12の傾斜側面23及び器具設置面20に達するため、LED11発光部とその周囲との輝度比が小さくなる。   As shown in FIG. 5, the cover 13 is attached to the fixture main body 12 so as to cover the front surface (light emitting surface) of the LED 11, so that the light emitted from the LED 11 does not directly enter the viewer's field of view and the luminance is reduced. Further, a part of the light emitted from the LED 11 is guided through the thickness of the cover 13 or diffusely reflected inside the cover 13, and then diffused by the convex portion 31, and the inclined side surface 23 of the instrument main body 12 and Since it reaches the appliance installation surface 20, the luminance ratio between the LED 11 light emitting section and its surroundings becomes small.

カバー13の内表面32と、LED11が取り付けられた面に対向するカバー13の外表面33が平滑で、カバー13の側面側の外表面34に細かい凹凸加工をした場合、導光及び乱反射する光を器具設置面20方向に効率的に拡散できるため、LED11発光部とその周囲との輝度比をより小さくすることができる。   Light that is guided and diffusely reflected when the inner surface 32 of the cover 13 and the outer surface 33 of the cover 13 facing the surface on which the LED 11 is mounted are smooth and the outer surface 34 on the side surface side of the cover 13 is finely uneven. Can be efficiently diffused in the direction of the appliance installation surface 20, so that the luminance ratio between the LED 11 light emitting portion and its surroundings can be further reduced.

以上のように、本実施の形態では、器具本体12の取付面21に対して垂直方向を照射する複数のLED11の照射方向に、器具本体12の断面の側面外形面よりも器具外に凸形状である拡散透光性を有するカバー13が設けられているため、光源より照射された光の一部を照明器具10の側面や器具設置面20に拡散させることができる。これにより、グレアが軽減でき、例えば室内天井に明るさ感が得られる照明器具10が提供できる。   As described above, in the present embodiment, in the irradiation direction of the plurality of LEDs 11 that irradiate the mounting surface 21 of the instrument main body 12 in the vertical direction, a convex shape is formed outside the instrument more than the side external surface of the cross section of the instrument main body 12. Since the cover 13 having diffuse translucency is provided, a part of the light irradiated from the light source can be diffused to the side surface of the lighting fixture 10 or the fixture installation surface 20. Thereby, glare can be reduced, for example, the lighting fixture 10 from which a feeling of brightness is obtained can be provided in an indoor ceiling.

また、本実施の形態では、器具本体12の側面が垂直な面ではなく、傾斜側面23となっているため、図4及び図5に示すように、カバー13の凸部31の側面、即ち、外表面34を垂直な面としても、LED11からの光を照明器具10の側面や器具設置面20に拡散させることができる。つまり、カバー13の凸部31を器具本体12の底面の端部25より外側に出っ張らせる必要がない。そのため、意匠性の高い照明器具10が提供できる。なお、凸部31は、器具本体12の傾斜側面23の延長面24よりも外側に突出しているのであれば、その側面が垂直な面ではなく、器具本体12の底面の端部25より内側に傾斜したり、湾曲したりしていてもよい。   In the present embodiment, since the side surface of the instrument body 12 is not a vertical surface but an inclined side surface 23, as shown in FIGS. 4 and 5, the side surface of the convex portion 31 of the cover 13, that is, Even if the outer surface 34 is a vertical surface, the light from the LED 11 can be diffused to the side surface of the lighting fixture 10 or the fixture installation surface 20. That is, it is not necessary to project the convex portion 31 of the cover 13 outward from the end portion 25 on the bottom surface of the instrument body 12. Therefore, the lighting fixture 10 with high designability can be provided. In addition, if the convex part 31 protrudes outside the extended surface 24 of the inclined side surface 23 of the instrument main body 12, the side surface is not a vertical surface, but inside the end portion 25 on the bottom surface of the instrument main body 12. It may be inclined or curved.

実施の形態2.
本実施の形態について、主に実施の形態1との差異を説明する。
Embodiment 2. FIG.
In the present embodiment, differences from the first embodiment will be mainly described.

図6は、本実施の形態に係る照明器具10の斜視図である。図7は、照明器具10の分解斜視図である。図8は、照明器具10の設置状態の側面図である。   FIG. 6 is a perspective view of the lighting fixture 10 according to the present embodiment. FIG. 7 is an exploded perspective view of the lighting fixture 10. FIG. 8 is a side view of the luminaire 10 in an installed state.

本実施の形態では、カバー13の凸部31の側面、即ち、外表面34が垂直な面ではなく、器具本体12の底面の端部25より外側に突出している。つまり、本実施の形態では、カバー13の凸部31を器具本体12の底面の端部25より外側に出っ張らせている。これにより、実施の形態1と比べて、より多くの光を照明器具10の側面や器具設置面20に拡散させることができる。   In the present embodiment, the side surface of the convex portion 31 of the cover 13, that is, the outer surface 34, is not a vertical surface but protrudes outward from the end portion 25 on the bottom surface of the instrument body 12. That is, in the present embodiment, the convex portion 31 of the cover 13 protrudes outside the end portion 25 on the bottom surface of the instrument body 12. Thereby, compared with Embodiment 1, more light can be diffused to the side surface of the lighting fixture 10 or the fixture installation surface 20.

実施の形態3.
本実施の形態について、主に実施の形態1との差異を説明する。
Embodiment 3 FIG.
In the present embodiment, differences from the first embodiment will be mainly described.

図9は、照明器具10の設置状態の側面図である。   FIG. 9 is a side view of the installation state of the lighting fixture 10.

本実施の形態では、器具本体12の断面が四角形状になっている。よって、器具本体12の側面26が傾斜側面23ではなく、垂直な面となっている。   In the present embodiment, the instrument body 12 has a square cross section. Therefore, the side surface 26 of the instrument main body 12 is not an inclined side surface 23 but a vertical surface.

本実施の形態において、照明器具10は、側面形状が略正方形からなる直方体形状の器具本体12と、この器具本体12に取り付けられるLED11と、このLED11の前面(発光面)を覆うように、器具本体12に取り付けられるカバー13を備える。なお、器具本体12の側面形状は、例えば長方形であっても構わない。   In the present embodiment, the lighting fixture 10 has a rectangular parallelepiped fixture main body 12 whose side shape is a substantially square shape, an LED 11 attached to the fixture main body 12, and a front surface (light emitting surface) of the LED 11 so as to cover it. A cover 13 attached to the main body 12 is provided. In addition, the side surface shape of the instrument main body 12 may be a rectangle, for example.

器具本体12は、天井等の器具設置面20に取り付けられる取付面21と、LED11から放射される光を出射する出射面22と、略平行な2つの側面26とを有する。   The appliance main body 12 has an attachment surface 21 attached to an appliance installation surface 20 such as a ceiling, an emission surface 22 that emits light emitted from the LED 11, and two substantially parallel side surfaces 26.

カバー13は、実施の形態2と同様に、側断面形状が楕円形となっている。カバー13の円弧状になる両端部(凸部31)は、器具本体12の側面26の延長面24から器具外方向に突出する。   As in the second embodiment, the cover 13 has an oval side cross-sectional shape. Both end portions (convex portions 31) of the cover 13 having an arcuate shape project outward from the extension surface 24 of the side surface 26 of the instrument body 12.

図10は、照明器具10の側面図であり、カバー13からの拡散光を図示したものである。   FIG. 10 is a side view of the luminaire 10 and illustrates diffused light from the cover 13.

図10に示すように、カバー13は、LED11の前面(発光面)を覆うように器具本体12に取り付けられるので、LED11が発する光が直接看者の視野に入らず、輝度が低減される。また、LED11から放射された光の一部は、カバー13の板厚内を導光したり、カバー13内部で乱反射したりした後に、凸部31で拡散し、器具本体12の傾斜側面23及び器具設置面20に達するため、LED11発光部とその周囲の輝度比が小さくなる。   As shown in FIG. 10, since the cover 13 is attached to the fixture main body 12 so as to cover the front surface (light emitting surface) of the LED 11, the light emitted from the LED 11 does not directly enter the viewer's field of view and the brightness is reduced. Further, a part of the light emitted from the LED 11 is guided through the thickness of the cover 13 or diffusely reflected inside the cover 13, and then diffused by the convex portion 31, and the inclined side surface 23 of the instrument main body 12 and Since it reaches the appliance installation surface 20, the luminance ratio between the LED 11 light emitting unit and its surroundings becomes small.

カバー13の内表面32と外表面33が平滑で、カバー13の凸部31の外表面34に細かい凹凸加工をした場合、導光及び乱反射する光を器具設置面20方向に効率的に拡散できるため、LED11発光部とその周囲の輝度比をより小さくすることができる。   When the inner surface 32 and the outer surface 33 of the cover 13 are smooth, and when the outer surface 34 of the convex portion 31 of the cover 13 is finely uneven, the light that is guided and diffusely reflected can be efficiently diffused in the direction of the instrument installation surface 20. Therefore, the luminance ratio between the LED 11 light emitting unit and its surroundings can be further reduced.
