A plurality of light emitting elements are arranged so as to be adjacent to each other in the second direction crossing the first direction, and the wavelength bands of the light emitted from the light emitting elements in the adjacent element rows partially overlap.
上記実施形態によると、第２の方向に隣接した複数の素子列のうち、第２の方向に沿った外側の素子列の発光素子が出射する光の波長帯域は、第２の方向に沿った内側の素子列の発光素子が出射する光の波長帯域より狭い。 According to the above embodiment, the wavelength band of the light emitted from the light emitting elements in the outer element row along the second direction out of the plurality of element rows adjacent in the second direction is along the second direction.

以下、図面を参照しながら実施形態について詳細に説明する。以下の説明では、照明装置１００を図示しない照明バトンなどに取り付けた使用状態で、照明光が出射される方向を前方と称し、その反対を後方と称する。また、照明装置１００を前方から見て上下方向および左右方向を規定する。各図において、左右方向をＸ軸で示し、上下方向をＹ軸で示し、前後方向をＺ軸で示す。 Hereinafter, embodiments will be described in detail with reference to the drawings. In the following description, the direction in which the illumination light is emitted is referred to as “front” and the opposite is referred to as “rear” in a usage state where the illumination device 100 is attached to an illumination baton (not shown). Further, the vertical direction and the horizontal direction are defined when the illumination device 100 is viewed from the front. In each figure, the horizontal direction is indicated by the X axis, the vertical direction is indicated by the Y axis, and the front and rear direction is indicated by the Z axis.
図１に示すように、実施形態に係る照明装置１００は、略矩形箱状の筐体１０１を有する。筐体１０１は、左右方向の寸法が上下方向の寸法より大きい。筐体１０１は、薄い金属板により形成されている。筐体１０１の表面は、黒色に塗装されている。筐体１０１の前面には、矩形の開口部１０２が設けられている。筐体１０１は、その前方に、ＸＹ平面と平行に配置された矩形枠状の前面板１０１ａを有する。開口部１０２は、前面板１０１ａの内周縁により規定されている。筐体１０１は、放熱のための複数のスリット状の通風孔１０１１を有する。 As illustrated in FIG. 1, the lighting device 100 according to the embodiment includes a substantially rectangular box-shaped housing 101. The casing 101 has a horizontal dimension larger than the vertical dimension. The casing 101 is formed of a thin metal plate. The surface of the housing 101 is painted black. A rectangular opening 102 is provided on the front surface of the housing 101. The casing 101 has a rectangular frame-shaped front plate 101a disposed in front of the casing 101 in parallel with the XY plane. The opening 102 is defined by the inner peripheral edge of the front plate 101a. The housing 101 has a plurality of slit-shaped ventilation holes 1011 for heat dissipation.
図１では、開口部１０２を覆う透光板１１０（図２）を筐体１０１から取り外した状態を図示してある。開口部１０２の縁には、断面略Ｌ字状の４枚の反射板１０３が取り付けられている。反射板１０３は、開口部１０２の４つの辺それぞれに設けられている。各反射板１０３は、一枚の金属板により形成されている。反射板１０３の表面は、白色に塗装されている。反射板１０３は、固定板部１０３ａと傾斜板部１０３ｂを一体に有する。固定板部１０３ａと傾斜板部１０３ｂは、反射板１０３を長手方向に沿った線で鈍角に折り曲げることにより形成される。 In FIG. 1, a state where the translucent plate 110 (FIG. 2) covering the opening 102 is removed from the housing 101 is illustrated. Four reflecting plates 103 having a substantially L-shaped cross section are attached to the edge of the opening 102. The reflection plate 103 is provided on each of the four sides of the opening 102. Each reflector 103 is formed of a single metal plate. The surface of the reflecting plate 103 is painted white. The reflection plate 103 integrally includes a fixed plate portion 103a and an inclined plate portion 103b. The fixed plate portion 103a and the inclined plate portion 103b are formed by bending the reflecting plate 103 at an obtuse angle along a line along the longitudinal direction.
各反射板１０３は、複数本のネジ１０４を用いて、筐体１０１の前面板１０１ａに固定される。つまり、複数本のネジ１０４により固定板部１０３ａを前面板１０１ａに締結固定することにより、反射板１０３が筐体１０１に固定される。反射板１０３は、傾斜板部１０３ｂが開口部１０２の縁から筐体１０１内に向けて内側に傾斜する向きで筐体１０１に取り付けられる。すなわち、反射板１０３の傾斜板部１０３ｂは、開口部１０２の縁から後方に向けて内側に傾斜している。 Each reflecting plate 103 is fixed to the front plate 101 a of the housing 101 using a plurality of screws 104. That is, the reflecting plate 103 is fixed to the housing 101 by fastening and fixing the fixing plate portion 103 a to the front plate 101 a with a plurality of screws 104. The reflecting plate 103 is attached to the housing 101 such that the inclined plate portion 103b is inclined inward from the edge of the opening 102 toward the inside of the housing 101. That is, the inclined plate portion 103 b of the reflecting plate 103 is inclined inward from the edge of the opening 102 toward the rear.
図２に示すように、透光板１１０は、筐体１０１の開口部１０２を覆う位置に配置される。つまり、透光板１１０は、各反射板１０３の傾斜板部１０３ｂを間に挟んで、前面板１０１ａの前方に重ねて配置される。透光板１１０の外周縁に沿って透光板１１０の前方には、矩形のカバー枠１１１が設けられている。カバー枠１１１は、開口部１０２の外側に配置される。つまり、透光板１１０の外周縁は、筐体１０１の前面板１０１ａ（反射板１０３の固定板部１０３ａ）とカバー枠１１１によって挟まれる。 As shown in FIG. 2, the translucent plate 110 is disposed at a position that covers the opening 102 of the housing 101. That is, the translucent plate 110 is disposed so as to overlap the front plate 101a with the inclined plate portion 103b of each reflecting plate 103 interposed therebetween. A rectangular cover frame 111 is provided in front of the light transmitting plate 110 along the outer peripheral edge of the light transmitting plate 110. The cover frame 111 is disposed outside the opening 102. That is, the outer peripheral edge of the translucent plate 110 is sandwiched between the front plate 101 a of the housing 101 (the fixed plate portion 103 a of the reflection plate 103) and the cover frame 111.
カバー枠１１１の内周縁には、透光板１１０に向けてわずかに傾斜した４つの傾斜片１１１ａが一体に設けられている。各傾斜片１１１ａの傾斜方向の先端縁は透光板１１０の表面に接触する。カバー枠１１１は、その四つの角部において、４本のネジ１１２を用いて筐体１０１の前面板１０１ａに締結固定されている。カバー枠１１１を前面板１０１ａに固定することで、透光板１１０が筐体１０１に取り付けられる。 Four inclined pieces 111 a that are slightly inclined toward the translucent plate 110 are integrally provided on the inner peripheral edge of the cover frame 111. The tip edge of each inclined piece 111a in the inclined direction is in contact with the surface of the light transmitting plate 110. The cover frame 111 is fastened and fixed to the front plate 101a of the housing 101 by using four screws 112 at the four corners. The translucent plate 110 is attached to the housing 101 by fixing the cover frame 111 to the front plate 101a.
透光板１１０は、例えば、白色の透明な熱に強い樹脂製の板により形成されている。透光板１１０は、後述する光源基板１０に実装した複数の発光素子１ａ〜１ｈ（図６参照）から出射される光を透過させる。発光素子１ａ〜１ｈから出射された光は、反射板１０３の傾斜板部１０３ｂで反射されて、或いは直接、透光板１１０に入射する。透光板１１０は、透過する光を拡散させる。つまり、透光板１１０は、複数の発光素子１ａ〜１ｈから出射される有彩色光を良好に混色し、照明装置１００から出射される照明光にムラを生じることを抑制し、均一で良質な照明光を提供する。 The translucent plate 110 is formed of, for example, a white transparent heat-resistant resin plate. The light transmissive plate 110 transmits light emitted from a plurality of light emitting elements 1a to 1h (see FIG. 6) mounted on the light source substrate 10 described later. Light emitted from the light emitting elements 1 a to 1 h is reflected by the inclined plate portion 103 b of the reflecting plate 103 or directly enters the light transmitting plate 110. The translucent plate 110 diffuses the transmitted light. That is, the translucent plate 110 mixes chromatic color light emitted from the plurality of light emitting elements 1a to 1h well, suppresses unevenness in illumination light emitted from the illumination device 100, and is uniform and high quality. Provide illumination light.
図３および図４に示すように、照明装置１００は、２つのハンドル１２１、１２２、および吊下げアーム１２４を備えている。一方のハンドル１２１は、筐体１０１の上方に固設されている。もう一方のハンドル１２２は、筐体１０１の下方に固設されている。各ハンドル１２１、１２２は、左右方向に延設された把持バー１２１ａ、１２２ａを有する。作業者は、照明装置１００を持ち運ぶ際に、２つのハンドル１２１、１２２の把持バー１２１ａ、１２２ａを両手でつかんで照明装置１００を持ち上げる。また、作業者は、照明バトンに取り付けた照明装置１００の角度を変える際に下方のハンドル１２２を掴んで首振り操作をする。 As shown in FIGS. 3 and 4, the lighting device 100 includes two handles 121 and 122 and a suspension arm 124. One handle 121 is fixed above the housing 101. The other handle 122 is fixed below the housing 101. Each handle 121, 122 has grip bars 121a, 122a extending in the left-right direction. When carrying the lighting device 100, the operator lifts the lighting device 100 by holding the grip bars 121 a and 122 a of the two handles 121 and 122 with both hands. Further, when changing the angle of the lighting device 100 attached to the lighting baton, the worker grasps the lower handle 122 and swings the head.
吊下げアーム１２４は、Ｕ字状に折り曲げられたパイプ１２５、図示しない照明バトンなどに照明装置１００を取り付けるための取付ロッド１２６、取付ロッド１２６をパイプ１２５の中央に固定するための固定具１２７、および吊下げアーム１２４（パイプ１２５）に対する照明装置１００の回動を規制および規制解除するためのロック機構１２８を有する。 The suspension arm 124 includes a pipe 125 bent in a U-shape, a mounting rod 126 for mounting the lighting device 100 on a lighting baton (not shown), a fixture 127 for fixing the mounting rod 126 to the center of the pipe 125, And a locking mechanism 128 for restricting and releasing the rotation of the lighting device 100 with respect to the suspension arm 124 (pipe 125).
取付ロッド１２６は、上下方向に延設され、Ｚ軸と平行な軸を中心に固定具１２７を左右方向に回動可能に支持する。つまり、照明装置１００は、照明バトンに取り付けた状態で、上下方向に沿った取付ロッド１２６を中心に左右方向に回動可能となる。固定具１２７は、取付板片１２７ｃを一体に有する。取付板片１２７ｃは、照明装置１００の脱落を防止するためのワイヤー１２７ａを取り付けるための取付孔１２７ｂを有する。ワイヤー１２７ａは、例えば照明バトンにかけられる。 The mounting rod 126 extends in the vertical direction, and supports the fixture 127 so as to be rotatable in the left-right direction around an axis parallel to the Z-axis. That is, the lighting device 100 can be rotated in the left-right direction around the mounting rod 126 along the up-down direction in a state of being mounted on the lighting baton. The fixture 127 integrally has a mounting plate piece 127c. The attachment plate piece 127c has an attachment hole 127b for attaching a wire 127a for preventing the lighting device 100 from falling off. The wire 127a is hung on an illumination baton, for example.
Ｕ字状のパイプ１２５の左右方向の幅は、筐体１０１（前面板１０１ａ）の左右方向の幅よりわずかに短い。このため、パイプ１２５の両端は、図２に示す方向（前方）から照明装置１００を見た場合に、筐体１０１の一部に隠れて見えない。一方、筐体１０１は、左右の側壁１０１ｂの間の幅が、後方に向けて段々に狭くなっている。つまり、側壁１０１ｂは、前面板１０１ａの縁から後方に向けて内側に傾斜した傾斜板部１０１ｂ−１、および傾斜板部１０１ｂ−１の後方の端縁に連続した取付板部１０１ｂ−２を有する。取付板部１０１ｂ−２は、ＹＺ平面と略平行に配置されている。 The width in the left-right direction of the U-shaped pipe 125 is slightly shorter than the width in the left-right direction of the housing 101 (front plate 101a). For this reason, both ends of the pipe 125 are hidden behind a part of the housing 101 and cannot be seen when the illumination device 100 is viewed from the direction (front) shown in FIG. On the other hand, in the case 101, the width between the left and right side walls 101b is gradually reduced toward the rear. That is, the side wall 101b has an inclined plate portion 101b-1 inclined inward from the edge of the front plate 101a toward the rear, and an attachment plate portion 101b-2 continuous with the rear edge of the inclined plate portion 101b-1. . The mounting plate portion 101b-2 is disposed substantially parallel to the YZ plane.
左右の取付板部１０１ｂ−２には、回動ピン１２５ａを介してパイプ１２５の両端が回動可能にそれぞれ取り付けられている。パイプ１２５の端部は、偏平な板状に潰されている。パイプ１２５の両端の板状部分１２５１は、ＹＺ平面と略平行に配置される。回動ピン１２５ａは、パイプ１２５の両端にある板状部分１２５１の孔（図示せず）に挿通されて取付板部１０１ｂ−２に固定される。このため、照明装置１００の筐体１０１は、パイプ１２５（吊下げアーム１２４）に対して、例えば、図３および図４に示す姿勢に上下方向に回動可能となっている。 Both ends of the pipe 125 are rotatably attached to the left and right attachment plate portions 101b-2 via rotation pins 125a. The end of the pipe 125 is crushed into a flat plate shape. The plate-like portions 1251 at both ends of the pipe 125 are disposed substantially parallel to the YZ plane. The rotation pin 125a is inserted through holes (not shown) in the plate-like portion 1251 at both ends of the pipe 125 and fixed to the mounting plate portion 101b-2. For this reason, the housing | casing 101 of the illuminating device 100 can be rotated to the up-down direction with respect to the pipe 125 (suspending arm 124), for example to the attitude | position shown in FIG. 3 and FIG.
また、筐体１０１の側壁１０１ｂの取付板部１０１ｂ−２には、ロック機構１２８の円板状の摩擦ディスク１２８ａが固設されている。摩擦ディスク１２８ａは、回動ピン１２５ａと同軸且つＹＺ平面と略平行に取り付けられている。ロック機構１２８は、摩擦ディスク１２８ａの表面に押し付ける図示しない摺接パッドを有する。また、ロック機構１２８は、摺接パッドを摩擦ディスク１２８ａの表面に離接させて押圧接触させるための操作レバー１２８ｂを有する。摺接パッドと操作レバー１２８ｂは、パイプ１２５の板状部分１２５１に取り付けられている。 Further, a disc-shaped friction disk 128a of the lock mechanism 128 is fixed to the mounting plate portion 101b-2 of the side wall 101b of the housing 101. The friction disk 128a is attached coaxially with the rotation pin 125a and substantially parallel to the YZ plane. The lock mechanism 128 has a sliding contact pad (not shown) that presses against the surface of the friction disk 128a. Further, the lock mechanism 128 has an operation lever 128b for bringing the sliding contact pad into contact with the surface of the friction disk 128a and pressing it. The sliding contact pad and the operation lever 128 b are attached to the plate-like portion 1251 of the pipe 125.
つまり、操作レバー１２８ｂを操作して、筐体１０１に固定した摩擦ディスク１２８ａにロック機構１２８の摺接パッドを押し付けることにより、摩擦ディスク１２８ａとパイプ１２５の板状部分１２５１を回動不能に固定することができる。これにより、照明装置１００の上下方向の傾倒角度を固定することができる。 That is, by operating the operation lever 128b and pressing the sliding contact pad of the lock mechanism 128 against the friction disk 128a fixed to the housing 101, the friction disk 128a and the plate-like portion 1251 of the pipe 125 are fixed to be non-rotatable. be able to.

以下、本実施形態の効果について説明する。
本実施形態の照明装置１００によると、各光源基板１０において、６色の原色（赤色、橙色、黄緑色、緑色、青緑色、青色）の光を出射する複数の発光素子１ａ〜１ｆを規則正しく配列したため、色域を広くすることができ、演色性をよくすることができる。このため、例えば、テレビカメラ撮影に適する照明光を作ることができる。
Hereinafter, the effect of this embodiment will be described.
According to the illuminating device 100 of this embodiment, in each light source board | substrate 10, several light emitting element 1a-1f which radiate | emits the light of six primary colors (red, orange, yellow-green, green, blue-green, blue) is regularly arranged. Therefore, the color gamut can be widened and the color rendering can be improved. For this reason, for example, illumination light suitable for TV camera photography can be made.
また、本実施形態では、白色光を出射する発光素子を用いずに６色の原色の光を混色させて白色光を作るため、表現可能な色域を広げた上で、白色の発光素子を実装するためのスペースを確保する必要がなく、装置構成を小型化することができる。また、白色の発光素子を用いないことで、原色の光を出射する際に、不要な色の光が混ざることがなく、所望する色の光を出射することができる。 In the present embodiment, the white light is produced by mixing the light of the six primary colors without using the light emitting element that emits white light. It is not necessary to secure a space for mounting, and the device configuration can be reduced in size. Further, by not using a white light emitting element, when emitting primary color light, unnecessary color light is not mixed and light of a desired color can be emitted.
見方を変えると、本実施形態の照明装置１００は、色域の広い演色性のよい照明光を出射する上で、必要最小限の色の光を出射する発光素子１ａ〜１ｆを用いている。このため、使用頻度の低い色の発光素子を実装する必要がなく、その分、使用頻度の高い発光素子だけを光源基板１０に実装することができ、照明装置１００全体として、発光効率を高めることができ、明るい照明光を出射することができる。 In other words, the illumination device 100 of the present embodiment uses the light emitting elements 1a to 1f that emit light of the minimum necessary color when emitting illumination light having a wide color gamut and good color rendering. For this reason, it is not necessary to mount a light emitting element with a low usage frequency, and only a light emitting element with a high usage frequency can be mounted on the light source substrate 10 accordingly, and the luminous efficiency of the lighting device 100 as a whole is increased. And bright illumination light can be emitted.
また、本実施形態の照明装置１００は、波長帯域が一部重なる素子列２ａ〜２ｆをＸ方向に並べて配列したため、照明装置１００として混色がよく、透光板１１０を透過した時点で良好に混色された照明光を出射することができる。このため、本実施形態の照明装置１００は、舞台照明やスタジオ照明に用いるフラッドライトに適している。 In addition, since the illumination device 100 of the present embodiment has the element rows 2a to 2f in which the wavelength bands partially overlap each other in the X direction, the illumination device 100 has a good color mixture as the illumination device 100 and mixes well when it passes through the light transmitting plate 110. The emitted illumination light can be emitted. For this reason, the illuminating device 100 of this embodiment is suitable for the floodlight used for stage lighting or studio lighting.
また、本実施形態によると、Ｘ方向に並んだ複数の素子列２ａ〜２ｆのうち、外側の素子列２ａ、２ｆの波長帯域が内側の素子列２ｂ、２ｃの波長帯域より狭くなっているため、Ｘ方向に隣接する素子列の波長帯域を重ね易い。仮に、波長帯域の比較的狭い素子列を内側に配列した場合、波長帯域の抜けを補うことが難しい。 Further, according to the present embodiment, among the plurality of element rows 2a to 2f arranged in the X direction, the wavelength bands of the outer element rows 2a and 2f are narrower than the wavelength bands of the inner element rows 2b and 2c. It is easy to overlap the wavelength bands of the element rows adjacent in the X direction. If an element array having a relatively narrow wavelength band is arranged inside, it is difficult to compensate for the loss of the wavelength band.
また、本実施形態によると、Ｘ方向に隣接する素子列の複数の発光素子１を千鳥状に配置したため、隣接する素子列同士で光を補って混色をより良好にすることができる。 In addition, according to the present embodiment, since the plurality of light emitting elements 1 in the element rows adjacent in the X direction are arranged in a staggered manner, light can be supplemented between the adjacent element rows to improve color mixing.
上述した実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。上述した実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。上述した実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。 The above-described embodiments are presented as examples and are not intended to limit the scope of the invention. The above-described embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. The above-described embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and equivalents thereof.
例えば、上述した実施形態では、同じ色の原色の光を出射する複数の発光素子をＹ方向に並べた素子列をＸ方向に複数列隣接させたレイアウトについて説明したが、これに限らず、複数の素子列をＸ方向に傾斜させてレイアウトしても良い。つまり、各素子列の延出方向と隣接方向は必ずしも直交する必要はない。 For example, in the above-described embodiment, the layout in which a plurality of element rows in which a plurality of light emitting elements that emit light of the same primary color are arranged in the Y direction are adjacent to each other in the X direction is described. These element rows may be laid out while being inclined in the X direction. That is, the extending direction of each element row and the adjacent direction are not necessarily orthogonal.
また、上述した実施形態では、発光素子１ｆと異なる色温度の青色光を出射する発光素子１ｇ、１ｈの素子列２ｇ、２ｈを設けたが、青色光以外の光を出射する発光素子の素子列を追加してもよい。 In the above-described embodiment, the light-emitting elements 1g and 1h that emit blue light having a color temperature different from that of the light-emitting element 1f are provided. The element arrays of light-emitting elements that emit light other than blue light. May be added.
