The predetermined angle θ is set to, for example, 45 ° so that light from the light emitting element 37 is irradiated from the end region 13b of the diffusion cover 13 to the central region 13a.
したがって、主光源15は、器具本体12内の第1の方向aの両端部側にそれぞれ設けられ、拡散カバー13の端部領域13bから中央領域13aに亘って対向し、拡散カバー13の端部領域13bから中央領域13aに亘って光を照射する。そして、1つの主光源15の光束は例えば3000lm程度で、照明装置10が備える2つの主光源15の合計の光束は6000lm程度となっている。 Therefore, the main light sources 15 are provided at both end sides in the first direction a in the appliance body 12, and are opposed from the end region 13 b to the central region 13 a of the diffusion cover 13. Light is irradiated from the region 13b to the central region 13a. The light flux of one main light source 15 is, for example, about 3000 lm, and the total light flux of the two main light sources 15 included in the lighting device 10 is about 6000 lm.
なお、主光源15は、拡散カバー13の端部領域13bに光を均一に照射するために、光拡散性を有する光源カバーで覆うようにしてもよい。 The main light source 15 may be covered with a light-diffusing light source cover in order to uniformly irradiate the end region 13b of the diffusion cover 13 with light.

副光源16は、主光源15が発光する光に含まれる所定の色光成分の光を発光する。副光源16が発光する色成分の光としては、例えば、青色や赤色のうちの1色またはそれらの2色、あるいは、赤色、緑色および青色の3色などの複数色の場合が含まれる。第1の実施形態では、副光源16は、青色の光を発光するものとする。 The sub light source 16 emits light of a predetermined color light component included in the light emitted by the main light source 15. The light of the color component emitted by the sub light source 16 includes, for example, one of blue or red or two of them, or a plurality of colors such as red, green and blue. In the first embodiment, the sub light source 16 emits blue light.
副光源16には、発光モジュール42が用いられている。発光モジュール42は、基板43、およびこの基板43に実装された複数の発光素子44を備えている。基板43は、器具本体12の第2方向bに細長い長方形に形成され、表面に配線パターンが形成されている。複数の発光素子44は、基板43の配線パターン上に、基板43の幅方向の中央に1列または複数列で、基板43の長手方向に沿って所定の間隔をあけて実装されている。発光素子44には、例えば表面実装形のLEDが用いられている。 As the sub light source 16, a light emitting module 42 is used. The light emitting module 42 includes a substrate 43 and a plurality of light emitting elements 44 mounted on the substrate 43. The board 43 is formed in a rectangular shape elongated in the second direction b of the instrument body 12, and has a wiring pattern formed on the surface.

副光源16は、発光素子44の光軸45が拡散カバー13の中央領域13aの頂部に垂直に対向するように、すなわち、発光素子44の光軸45が器具本体12の下面に対して垂直となるように、器具本体12の天板20の下面中央に取り付けられている。 The auxiliary light source 16 is arranged such that the optical axis 45 of the light emitting element 44 is vertically opposed to the top of the central area 13a of the diffusion cover 13, that is, the optical axis 45 of the light emitting element 44 is perpendicular to the lower surface of the instrument body 12. In this way, it is attached to the center of the lower surface of the top plate 20 of the instrument body 12.
したがって、副光源16は、器具本体12内の中央に設けられ、拡散カバー13の中央領域13aに対向し、拡散カバー13の中央領域13aに光を照射する。そして、副光源16の光束は、副光源16の光が青色光の場合には例えば270lm程度となっている。なお、照明装置10が主光源15からの光による主照明の機能を維持し、かつ副光源16からの光によって空間が変色することを抑制するためには、副光源16の光束は1つの主光源15の光束よりも小さく、例えば1/5以下、さらには1/7以下であることが好ましい。 Therefore, the auxiliary light source 16 is provided at the center of the instrument body 12 and faces the central area 13a of the diffusion cover 13 to irradiate the central area 13a of the diffusion cover 13 with light. The light flux of the sub light source 16 is, for example, about 270 lm when the light of the sub light source 16 is blue light. In order for the lighting device 10 to maintain the function of the main illumination by the light from the main light source 15 and to prevent the space from being discolored by the light from the sub light source 16, the light flux of the sub light source 16 It is preferably smaller than the light flux of the light source 15, for example, 1/5 or less, more preferably 1/7 or less.

The dimmer 50 includes main power supply units 51 and 51b for individually supplying power to the first main light source 15a and the second main light source 15b of the main light source 15, and a sub power supply unit for supplying power to the sub light source 16. A dimming signal is input to 52 to turn on / off and dimming the first main light source 15a, the second main light source 15b, and the sub light source 16 of the main light source 15, respectively. The light control device 50 includes a control unit 53. The control unit 53 controls the light control of each of the first main light source 15a and the second main light source 15b individually, and thereby controls the color control of the main light source 15. The control unit 53 controls the increase or decrease of the light of the sub light source 16 according to the input dimming signal. Note that the main power supply units 51a and 51b and the sub power supply unit 52 that supplies power to the sub light source 16 may be provided integrally with the dimmer 50.

主光源15および副光源16にそれぞれ主電源部51a,51bおよび副電源部52から電源を供給することにより、主光源15および副光源16がそれぞれ点灯する。 By supplying power to the main light source 15 and the sub light source 16 from the main power supply units 51a and 51b and the sub power supply unit 52, respectively, the main light source 15 and the sub light source 16 are turned on.
主光源15からの光が拡散カバー13の端部領域13bから中央領域13aに照射され、副光源16からの光が拡散カバー13の中央領域13aに照射され、拡散カバー13の発光面13Dが光る。 The light from the main light source 15 is irradiated from the end region 13b of the diffusion cover 13 to the central region 13a, the light from the sub light source 16 is irradiated to the central region 13a of the diffusion cover 13, and the light emitting surface 13D of the diffusion cover 13 shines .
この場合、図5に示すように、拡散カバー13の端部領域13bは主光源15からの光によって昼光色(または電球色)に光り、拡散カバー13の中央領域13aは副光源16からの光によって青色に光る。 In this case, as shown in FIG. 5, the end region 13b of the diffusion cover 13 is illuminated in daylight (or light bulb color) by light from the main light source 15, and the central region 13a of the diffusion cover 13 is illuminated by light from the sub light source 16. Glows blue.
拡散カバー13を透過した主光源15からの光が照明空間に照射される。この場合、主光源15が器具本体12の端部側に設けられ、主光源15の光軸38を照明装置10の中央方向に向けて傾斜させていることにより、埋込形の照明装置10であっても広い配光角の領域に主光源15からの光を照射することができる。 Light from the main light source 15 transmitted through the diffusion cover 13 is applied to the illumination space. In this case, the main light source 15 is provided on the end side of the fixture body 12, and the optical axis 38 of the main light source 15 is inclined toward the center of the lighting device 10, so that the embedded lighting device 10 Even so, light from the main light source 15 can be applied to a region having a wide light distribution angle.
拡散カバー13の中央領域13aに照射される副光源16からの光は、その拡散カバー13の中央領域13aが青色に染まる程度の光束であるため、拡散カバー13の中央領域13aを透過して照明空間に照射される青色の光の光量は主光源15からの光に比べて少ない。 The light from the sub light source 16 illuminated on the central area 13a of the diffusion cover 13 is a light flux such that the central area 13a of the diffusion cover 13 is dyed blue, so that the light is transmitted through the central area 13a of the diffusion cover 13 and illuminated. The amount of blue light applied to the space is smaller than the light from the main light source 15.
そのため、照明空間には、主として主光源15からの光が照射され、例えば読書や作業を行うのに適した照明環境となる。 For this reason, the illumination space is mainly irradiated with light from the main light source 15, which provides an illumination environment suitable for, for example, reading and working.
また、拡散カバー13の中央領域13aには、主光源15からの光と副光源16からの光との両方が照射されるが、主光源15からの光の光量が拡散カバー13の端部領域13bから中央領域13aに向かうに従って徐々に少なくなるとともに、副光源16からの光の光量が拡散カバー13の中央領域13aの周辺から中央に向かうに従って徐々に多くなる。そのため、拡散カバー13の端部領域13bと中央領域13aとの間には、白色と青色との間で徐々に色が変わるグラデーション領域が形成される。そのため、照明装置10を見上げた際、拡散カバー13の色がグラデーション領域を介して自然に変化しているように見え、光演出効果を高めることができる。 The central region 13a of the diffusion cover 13 is irradiated with both the light from the main light source 15 and the light from the sub light source 16, but the amount of light from the main light source 15 is reduced to the end region of the diffusion cover 13. The amount of light from the sub light source 16 gradually increases from the periphery of the central region 13a of the diffusion cover 13 toward the center while gradually decreasing from the center 13a toward the central region 13a. Therefore, between the end region 13b and the central region 13a of the diffusion cover 13, a gradation region whose color gradually changes between white and blue is formed. Therefore, when looking up at the lighting device 10, the color of the diffusion cover 13 appears to change naturally via the gradation area, and the light effect can be enhanced.
拡散カバー13の中央領域13aは、副光源16の光色が青色であっても、この青色と主光源15から出射した白色光とが混色することで、空色に近い青色となる。この場合、照明装置10を見上げた人は、空が連想されやすく、開放感やリラックス感が得られやすくなる。 Even if the light color of the sub light source 16 is blue, the central region 13a of the diffusion cover 13 becomes a blue color close to sky blue by mixing the blue color with the white light emitted from the main light source 15. In this case, a person who looks up at the lighting device 10 is easily associated with the sky, and a sense of openness and a sense of relaxation are easily obtained.
したがって、照明装置10によれば、主光源15からの光による主照明の機能を維持しながら、光演出効果を得ることができる。 Therefore, according to the lighting device 10, it is possible to obtain a light effect while maintaining the function of the main lighting by the light from the main light source 15.
さらに、拡散カバー13の中央領域13aが器具本体12の内側に窪むように湾曲しているため、副光源16からの光で光る拡散カバー13の中央領域13aが遠くにあるような奥行き感や開放感が得られやすく、光演出効果を向上できる。 Further, since the central area 13a of the diffusion cover 13 is curved so as to be depressed inside the instrument body 12, the depth and the open feeling as if the central area 13a of the diffusion cover 13 illuminated by the light from the auxiliary light source 16 are far away. And the light effect can be improved.
次に、主光源15を調色する場合について、制御部53による主光源15および副光源16の制御を、図1を参照して説明する。図1の横軸は主光源15の相関色温度、縦軸は主光源15および副光源16の光の強さを示している。 Next, control of the main light source 15 and the sub light source 16 by the control unit 53 in the case where the main light source 15 is toned will be described with reference to FIG. 1, the horizontal axis indicates the correlated color temperature of the main light source 15, and the vertical axis indicates the light intensity of the main light source 15 and the sub light source 16.
主光源15の相関色温度が最も低い2700Kの場合には、第1の主光源15aの光の割合は略0%、第2の主光源15bの光の割合は100%である。また、主光源15の相関色温度が最も高い5000Kの場合には、第1の主光源15aの光の割合は100%、第2の主光源15bの光の割合は0%に近い小さい値にある。図1は便宜上、主光源15の出力が一定となるように相関色温度が2700Kから5000Kまで変化するときの第1の主光源15aおよび第2の主光源15bの光の強さおよび副光源16の光の強さを示している。したがって、本実施形態では相関色温度を一定にした状態で主光源15の光出力を変化させることも可能である。 When the correlated color temperature of the main light source 15 is 2700K, which is the lowest, the ratio of the light of the first main light source 15a is approximately 0%, and the ratio of the light of the second main light source 15b is 100%. In the case where the correlated color temperature of the main light source 15 is 5000 K, which is the highest, the light ratio of the first main light source 15a is 100%, and the light ratio of the second main light source 15b is a small value close to 0%. is there. FIG. 1 shows, for convenience, the light intensity of the first main light source 15a and the second main light source 15b and the sub light source 16 when the correlated color temperature changes from 2700K to 5000K so that the output of the main light source 15 becomes constant. Shows the light intensity of Therefore, in the present embodiment, it is also possible to change the light output of the main light source 15 while keeping the correlated color temperature constant.
そして、主光源15の明るさが一定(照度が一定)で、主光源15の相関色温度を調色する場合、相関色温度を2700Kから高くしていくと、第1の主光源15aの光が増加し、第2の主光源15bの光が減少していく。このとき、相関色温度の上昇とともに、出射光に含まれる割合が増加する色成分を主光源15に含まれる所定の色成分とする。本実施形態では所定の色成分を青色成分として説明する。同様に、相関色温度を5000Kから低くしていくと、第1の主光源15aの光が減少し、第2の主光源15bの光が増加していく。このとき、上述した通り相関色温度の低下とともに、出射光に含まれる所定の色成分の割合は減少する。したがって、第1の主光源15aの光の増減と第2の主光源15bの光の増減とが逆転していることにより、主光源15の明るさが一定(照度が一定)で、主光源15の相関色温度が調色される。 In the case where the brightness of the main light source 15 is constant (the illuminance is constant) and the correlated color temperature of the main light source 15 is toned, the light of the first main light source 15a is increased by increasing the correlated color temperature from 2700K. Increases, and the light of the second main light source 15b decreases. At this time, a color component whose proportion included in the emitted light increases with an increase in the correlated color temperature is defined as a predetermined color component included in the main light source 15. In the present embodiment, the predetermined color component will be described as a blue component. Similarly, when the correlated color temperature is lowered from 5000 K, the light of the first main light source 15a decreases and the light of the second main light source 15b increases. At this time, as described above, as the correlated color temperature decreases, the ratio of the predetermined color component included in the emitted light decreases. Therefore, since the increase and decrease of the light of the first main light source 15a and the increase and decrease of the light of the second main light source 15b are reversed, the brightness of the main light source 15 is constant (the illuminance is constant), and Are correlated with each other.
また、第1の主光源15aと第2の主光源15bとの光が混光したときの相関色温度が所定値よりも小さい場合、すなわち所定の色成分の光が含まれる割合が所定値よりも小さい場合、第1の主光源15aの光の増加に準じて、副光源16の光を増減する。つまり、第1の主光源15aの光が増加して相関色温度が高くなるとき、言い換えると主光源15に含まれる所定の色成分の割合が高くなるときには副光源16の光も増加し、第1の主光源15aの光が減少し相関色温度が低くなるとき、言い換えると所定の色成分の光が含まれる割合が所定値よりも小さいときには副光源16の光も減少する。 Further, when the correlated color temperature when the light of the first main light source 15a and the light of the second main light source 15b are mixed is smaller than a predetermined value, that is, the ratio of the light containing the predetermined color component is larger than the predetermined value. Is smaller, the light of the sub light source 16 is increased or decreased according to the increase of the light of the first main light source 15a. That is, when the light of the first main light source 15a increases and the correlated color temperature increases, in other words, when the ratio of the predetermined color component included in the main light source 15 increases, the light of the sub light source 16 also increases, When the light of the first main light source 15a decreases and the correlated color temperature decreases, in other words, when the ratio of the light containing the predetermined color component is smaller than a predetermined value, the light of the sub light source 16 also decreases.
これにより、発光面13Dの端部領域13bが昼光色になっていくのに伴って発光面13Dの中央領域13aの青色感を強くし、青空のような演出効果が得られ、また、発光面13Dの端部領域13bが電球色になっていくのに伴って発光面13Dの中央領域13aの青色感を弱くし、夕焼け空のような演出効果を得ることができる。 Thereby, as the end region 13b of the light emitting surface 13D becomes daylight-colored, the blue feeling of the central region 13a of the light emitting surface 13D is strengthened, and an effect such as a blue sky is obtained, and the light emitting surface 13D As the end region 13b becomes light-bulb color, the blue feeling of the central region 13a of the light emitting surface 13D is weakened, and an effect like a sunset sky can be obtained.
また、第1の主光源15aと第2の主光源15bとの光が混光したときの相関色温度が所定値よりも大きい場合、すなわち所定の色成分の光が含まれる割合が所定値よりも大きい場合、副光源16の光の増減を、第1の主光源15aの光の増減に対して逆転させる。つまり、第1の主光源15aの光が増加して相関色温度が高くなるとき、言い換えると主光源15に含まれる所定の色成分の割合が高くなるときには副光源16の光が減少し、第1の主光源15aの光が減少して相関色温度が低くなるとき、言い換えると所定の色成分の光が含まれる割合が小さくなるときには副光源16の光が増加する。なお、主光源15に含まれる所定の色成分の割合が所定値を超えたときには副光源16の光出力を低下させる態様については種々選択することができる。例えば、主光源15の出射光に含まれる所定の色成分の増加に伴って一定の割合で減少させても良いし、任意の相関色温度のときに消灯させてもよい。 Further, when the correlated color temperature when the light of the first main light source 15a and the light of the second main light source 15b are mixed is larger than a predetermined value, that is, the ratio of the light of the predetermined color component is larger than the predetermined value. Is larger, the increase / decrease of the light of the sub light source 16 is reversed with respect to the increase / decrease of the light of the first main light source 15a. That is, when the light of the first main light source 15a increases and the correlated color temperature increases, in other words, when the ratio of the predetermined color component included in the main light source 15 increases, the light of the sub light source 16 decreases, The light of the sub light source 16 increases when the light of the first main light source 15a decreases and the correlated color temperature decreases, in other words, when the ratio of the light of the predetermined color component included decreases. It should be noted that various modes can be selected for reducing the light output of the sub light source 16 when the ratio of the predetermined color component included in the main light source 15 exceeds a predetermined value. For example, it may be reduced at a fixed rate as the predetermined color component included in the light emitted from the main light source 15 increases, or may be turned off at an arbitrary correlated color temperature.
これにより、発光面13Dの端部領域13bに、例えば4500K以上の高い相関色温度の白色光が照射されるのに伴って、発光面13Dの中央領域13aが青くなり過ぎて違和感が生じ、演出効果が得られなくなるのを防止できる。 With this, as the end region 13b of the light emitting surface 13D is irradiated with white light having a high correlated color temperature of, for example, 4500K or more, the central region 13a of the light emitting surface 13D becomes too blue, giving a sense of incongruity. The effect can be prevented from being lost.
なお、所定値Aは、主光源15の出力が一定となるように相関色温度を2700Kから5000Kまで変化させたときに、所定の色成分の割合が所定値になるときの第1の主光源15aの光の強さである。所定値Aのときの副光源16の光の強さは発光面13Dに形成される空の演出効果が得られるとともに違和感を感じないような値に適宜設定される。また、所定の相関色温度のときの副光源16の光の強さは、主光源15の出力が小さいほど小さくなり、その具体的な数値は適宜設定することができ、その値を変更することもできる。 When the correlated color temperature is changed from 2700 K to 5000 K so that the output of the main light source 15 is constant, the predetermined value A is the first main light source when the ratio of the predetermined color component becomes the predetermined value. 15a light intensity. The light intensity of the sub light source 16 at the predetermined value A is appropriately set to such a value that the effect of rendering the sky formed on the light emitting surface 13D can be obtained and the user does not feel uncomfortable. In addition, the light intensity of the sub light source 16 at a predetermined correlated color temperature decreases as the output of the main light source 15 decreases, and a specific numerical value can be appropriately set. Can also.
したがって、照明装置10によれば、主光源15の調色時に、副光源16を適切に制御することができ、そのため、照明装置10の発光面13Dで違和感のない演出効果が得られる。 Therefore, according to the illuminating device 10, the sub light source 16 can be appropriately controlled when the main light source 15 is toned, and therefore, the effect of producing an unnatural feeling can be obtained on the light emitting surface 13D of the illuminating device 10.
次に、図8に第2の実施形態を示す。なお、第1の実施形態と同じ構成については同じ符号を用い、その構成および作用効果についての説明を省略する。 Next, FIG. 8 shows a second embodiment. Note that the same components as those of the first embodiment are denoted by the same reference numerals, and the description of the configuration, operation, and effect is omitted.
図8の横軸は主光源15の相関色温度、縦軸は主光源15および副光源16の光の強さを示している。 8, the horizontal axis indicates the correlated color temperature of the main light source 15, and the vertical axis indicates the light intensity of the main light source 15 and the sub light source 16.
上述したように、制御部53により、主光源15は、明るさが一定(照度が一定)で、相関色温度が調色され、また、調色に応じて副光源16も制御される。 As described above, the controller 53 controls the main light source 15 so that the brightness is constant (illuminance is constant), the correlated color temperature is toned, and the sub light source 16 is also controlled according to the toning.
本実施形態では主光源15に含まれる所定の色成分を赤色として説明する。第2の主光源15bの光が所定値Bよりも小さい場合、主光源15に含まれる所定の色成分の割合が所定値よりも小さいときに第2の主光源15bの光の増加に準じて、副光源16の光を増減する。つまり、第2の主光源15bの光が増加して相関色温度が低くなるときには副光源16の光も増加し、第2の主光源15bの光が減少して相関色温度が高くなるときには副光源16の光も減少する。 In the present embodiment, the predetermined color component included in the main light source 15 is described as red. When the light of the second main light source 15b is smaller than the predetermined value B, when the ratio of the predetermined color component included in the main light source 15 is smaller than the predetermined value, the light of the second main light source 15b is increased. , The light of the sub light source 16 is increased or decreased. In other words, when the light of the second main light source 15b increases and the correlated color temperature decreases, the light of the auxiliary light source 16 also increases. When the light of the second main light source 15b decreases and the correlated color temperature increases, the auxiliary light temperature increases. The light of the light source 16 also decreases.
これにより、発光面13Dの端部領域13bが電球色になっていくのに伴って発光面13Dの中央領域13aにおいて、日中から夕方にかけての空のような演出効果が得られ、また、発光面13Dの端部領域13bが昼光色になっていくのに伴って発光面13Dの中央領域13aの赤色が弱くなって、違和感を感じることがないようにすることができる。 Thereby, as the end region 13b of the light emitting surface 13D becomes a light bulb color, in the central region 13a of the light emitting surface 13D, an effect like a sky from daytime to evening can be obtained, and As the end region 13b of the surface 13D becomes daylight-colored, the red color of the central region 13a of the light-emitting surface 13D becomes weaker, and it is possible to prevent the user from feeling uncomfortable.
また、第2の主光源15bの光が所定値Bよりも大きい場合、すなわち主光源15に含まれる所定の色成分の割合が所定値よりも大きい場合、副光源16の光の増減を、第2の主光源15bの光の増減に対して逆転させる。つまり、第2の主光源15bの光が増加して相関色温度が低くなるときには副光源16の光が減少し、第2の主光源15bの光が減少して相関色温度が高くなるときには副光源16の光が増加する。 When the light of the second main light source 15b is larger than the predetermined value B, that is, when the ratio of the predetermined color component included in the main light source 15 is larger than the predetermined value, the increase or decrease of the light of the sub light source 16 is performed. The second light source 15b is reversed with respect to the increase or decrease of the light. That is, when the light of the second main light source 15b increases and the correlated color temperature decreases, the light of the sub light source 16 decreases. When the light of the second main light source 15b decreases and the correlated color temperature increases, the sub light source 16b decreases. The light of the light source 16 increases.
これにより、発光面13Dの端部領域13bの電球色感が強くなったときには、発光面13Dの中央領域13aが赤くなり過ぎるのを防止し、違和感のない夕焼け空のような演出効果が得られるようにできる。 Thereby, when the color of the bulb in the end region 13b of the light emitting surface 13D becomes strong, it is possible to prevent the central region 13a of the light emitting surface 13D from becoming too red, and it is possible to obtain an effect such as a sunset sky without a sense of discomfort. I can do it.
そして、所定値Bは、発光面13Dに形成される空の演出効果が得られるとともに違和感を感じないような値に適宜設定され、例えば相関色温度が3000Kのところが好ましい。 The predetermined value B is appropriately set to such a value that the effect of producing the sky formed on the light emitting surface 13D is obtained and the user does not feel uncomfortable. For example, it is preferable that the correlated color temperature is 3000K.
したがって、照明装置10によれば、主光源15の調色時に、副光源16を適切に制御することができ、そのため、照明装置10の発光面13Dで違和感のない演出効果が得られる。 Therefore, according to the illuminating device 10, the sub light source 16 can be appropriately controlled when the main light source 15 is toned, and therefore, the effect of producing an unnatural feeling can be obtained on the light emitting surface 13D of the illuminating device 10.
次に、図9に第3の実施形態を示す。なお、第1の実施形態と同じ構成については同じ符号を用い、その構成および作用効果についての説明を省略する。 Next, FIG. 9 shows a third embodiment. Note that the same components as those of the first embodiment are denoted by the same reference numerals, and the description of the configuration, operation, and effect is omitted.
図9の横軸は主光源15の相関色温度、縦軸は主光源15および副光源16の光の強さを示している。 The horizontal axis in FIG. 9 shows the correlated color temperature of the main light source 15, and the vertical axis shows the light intensity of the main light source 15 and the sub light source 16.
上述したように、制御部53により、主光源15は、明るさが一定(照度が一定)で、相関色温度が調色され、また、調色に応じて副光源16も制御される。 As described above, the controller 53 controls the main light source 15 so that the brightness is constant (illuminance is constant), the correlated color temperature is toned, and the sub light source 16 is also controlled according to the toning.
所定値としては、第1の主光源15aの光の大きさを閾値となる第1の所定値C1と、第2の主光源15bの光を大きさの閾値となる第2の所定値C2が設けられている。 As the predetermined value, a first predetermined value C1 that sets the light intensity of the first main light source 15a as a threshold value and a second predetermined value C2 that sets the light intensity of the second main light source 15b as a threshold value are set. Is provided.
第1の主光源15aの光が第1の所定値C1よりも小さいとともに第2の主光源15bの光が第2の所定値C2よりも小さい場合、副光源16の光を一定、または相関色温度の上昇に伴って僅かに上昇または下降するものとする。 When the light of the first main light source 15a is smaller than the first predetermined value C1 and the light of the second main light source 15b is smaller than the second predetermined value C2, the light of the sub light source 16 is fixed or a correlated color. It shall rise or fall slightly as the temperature rises.
また、第1の主光源15aの光が第1の所定値C1よりも大きい場合、第1の主光源15aの光の増減に対して逆転させて副光源16の光を増減する。つまり、第1の主光源15aの光が増加して相関色温度が高くなるときには副光源16の光が減少し、第1の主光源15aの光が減少し、第2の主光源15bの光が増加して相関色温度が低くなるときには副光源16の光が増加する。 When the light of the first main light source 15a is larger than the first predetermined value C1, the light of the sub light source 16 is increased / decreased by reversing the increase / decrease of the light of the first main light source 15a. That is, when the light of the first main light source 15a increases and the correlated color temperature increases, the light of the sub light source 16 decreases, the light of the first main light source 15a decreases, and the light of the second main light source 15b decreases. Increases and the correlated color temperature decreases, the light of the sub light source 16 increases.
これにより、発光面13Dの端部領域13bが昼光色になっていくのに伴って、発光面13Dの中央領域13aが青くなり過ぎるのを防止できる。 Accordingly, it is possible to prevent the central region 13a of the light emitting surface 13D from becoming too blue as the end region 13b of the light emitting surface 13D becomes daylighting.
また、第2の主光源15bの光が所定値C2よりも大きい場合、つまり主光源15の出射光に所定の色成分が含まれる割合が所定値以下のときには副光源16の光が減少する。 Further, when the light of the second main light source 15b is larger than the predetermined value C2, that is, when the ratio of the light emitted from the main light source 15 containing the predetermined color component is equal to or less than the predetermined value, the light of the sub light source 16 decreases.
これにより、発光面13Dの端部領域13bの電球色感が強くなったときには、発光面13Dの中央領域13aの青色感を弱くし、夕焼け空のような演出効果が得られるようにできる。つまり、発光面13Dの端部領域13bの電球色感が強くなっていくのに、発光面13Dの中央領域13aの青色で光ってしまうと、夕焼け空のような演出効果が得られなくなるのを防止できる。 Thus, when the color sense of the bulb in the end region 13b of the light emitting surface 13D becomes strong, the blue color feeling in the central region 13a of the light emitting surface 13D is weakened, and an effect such as a sunset sky can be obtained. In other words, while the color of the bulb in the end region 13b of the light-emitting surface 13D becomes stronger, if it shines in blue in the central region 13a of the light-emitting surface 13D, it will not be possible to obtain the effect of a sunset sky. Can be prevented.
そして、所定値C1,C2は、発光面13Dに形成される空の演出効果が得られるとともに違和感を感じないような値に適宜設定される。第1の所定値C1は、例えば相関色温度が4500Kのところが好ましく、第2の所定値C2は、例えば相関色温度が3500Kのところが好ましい。 Then, the predetermined values C1 and C2 are appropriately set to values that provide the effect of producing the sky formed on the light emitting surface 13D and do not cause a feeling of strangeness. Preferably, the first predetermined value C1 is, for example, where the correlated color temperature is 4500K, and the second predetermined value C2 is, for example, where the correlated color temperature is 3500K.
したがって、照明装置10によれば、主光源15の調色時に、副光源16を適切に制御することができ、そのため、照明装置10の発光面13Dで違和感のない演出効果が得られる。 Therefore, according to the illuminating device 10, the sub light source 16 can be appropriately controlled when the main light source 15 is toned, and therefore, the effect of producing an unnatural feeling can be obtained on the light emitting surface 13D of the illuminating device 10.
次に、図10に第4の実施形態を示す。なお、第3の実施形態と同じ構成については同じ符号を用い、その構成および作用効果についての説明を省略する。 Next, FIG. 10 shows a fourth embodiment. Note that the same components as those of the third embodiment are denoted by the same reference numerals, and the description of the configurations and the effects will be omitted.
図10の横軸は主光源15の相関色温度、縦軸は主光源15および副光源16の光の強さを示している。 The horizontal axis in FIG. 10 shows the correlated color temperature of the main light source 15, and the vertical axis shows the light intensity of the main light source 15 and the sub light source 16.
上述した図9の第3の実施形態に対して、第1の主光源15aの光が第1の所定値C1よりも小さいとともに第2の主光源15bの光が第2の所定値C2よりも小さい場合、第1の主光源15aの増減に準じて、あるいは、第2の主光源15bの増減に逆転させて、副光源16の光を増加させる。 9, the light of the first main light source 15a is smaller than the first predetermined value C1, and the light of the second main light source 15b is smaller than the second predetermined value C2. If it is smaller, the light of the sub light source 16 is increased in accordance with the increase or decrease of the first main light source 15a or in reverse to the increase or decrease of the second main light source 15b.
これにより、発光面13Dの端部領域13bが電球色から昼光色に変化する場合、発光面13Dの中央領域13aの青色感を強くし、青空のような演出効果を得ることができる。 Thereby, when the end region 13b of the light emitting surface 13D changes from the bulb color to the daylight color, the blue feeling of the central region 13a of the light emitting surface 13D can be enhanced, and an effect like a blue sky can be obtained.
次に、図11に第5の実施形態を示す。なお、第3の実施形態と同じ構成については同じ符号を用い、その構成および作用効果についての説明を省略する。 Next, FIG. 11 shows a fifth embodiment. Note that the same components as those of the third embodiment are denoted by the same reference numerals, and the description of the configurations and the effects will be omitted.
図11の横軸は主光源15の相関色温度、縦軸は主光源15および副光源16の光の強さを示している。 11, the horizontal axis indicates the correlated color temperature of the main light source 15, and the vertical axis indicates the light intensity of the main light source 15 and the sub light source 16.
上述した図9の第3の実施形態に対して、第1の主光源15aの光が第1の所定値C1よりも小さいとともに第2の主光源15bの光が第2の所定値C2よりも小さい場合、第2の主光源15bの増減に準じて、あるいは、第1の主光源15aの増減に逆転させて、副光源16の光を増加させる。 9, the light of the first main light source 15a is smaller than the first predetermined value C1, and the light of the second main light source 15b is smaller than the second predetermined value C2. If it is smaller, the light of the sub light source 16 is increased in accordance with the increase or decrease of the second main light source 15b or reversed to the increase or decrease of the first main light source 15a.
これにより、第1の主光源15aの光が強くなるにつれて、その光で発光面13Dの中央領域13aがより青色感が出るため、第2の主光源16の光を弱くすることにより、発光面13Dの中央領域13aが青色感を一定に保つことができる。 As a result, as the light of the first main light source 15a becomes stronger, the light causes the central region 13a of the light emitting surface 13D to appear more blue, and thus the light of the second main light source 16 is weakened. The central region 13a of 13D can keep the blue feeling constant.
次に、図12および図13に第6の実施形態を示す。なお、上述した各実施形態と同じ構成については同じ符号を用い、その構成および作用効果についての説明を省略する。 Next, FIGS. 12 and 13 show a sixth embodiment. Note that the same reference numerals are used for the same configurations as those in the above-described embodiments, and descriptions of the configurations and operational effects are omitted.
図13に示すように、副光源16は、青色の光を発光する第1の副光源16a、および赤色の光を発光する第2の副光源16bを備える。また、副電源部として、第1の副光源16aに電源を供給する第1の副電源部52a、および第2の副光源16bに電源を供給する第2の副電源部52bを備える。 As shown in FIG. 13, the sub light source 16 includes a first sub light source 16a that emits blue light and a second sub light source 16b that emits red light. In addition, as a sub power supply unit, a first sub power supply unit 52a that supplies power to the first sub light source 16a and a second sub power supply unit 52b that supplies power to the second sub light source 16b are provided.
図12の横軸は主光源15の相関色温度、縦軸は主光源15および副光源16の光の強さを示している。 12, the horizontal axis indicates the correlated color temperature of the main light source 15, and the vertical axis indicates the light intensity of the main light source 15 and the sub light source 16.
上述したように、制御部53により、主光源15は、明るさが一定(照度が一定)で、相関色温度が調色され、また、調色に応じて副光源16も制御される。 As described above, the controller 53 controls the main light source 15 so that the brightness is constant (illuminance is constant), the correlated color temperature is toned, and the sub light source 16 is also controlled according to the toning.
所定値としては、第1の主光源15aの光の大きさを閾値となる第1の所定値C1と、第2の主光源15bの光を大きさの閾値となる第2の所定値C2が設けられている。 As the predetermined value, a first predetermined value C1 that sets the light intensity of the first main light source 15a as a threshold value and a second predetermined value C2 that sets the light intensity of the second main light source 15b as a threshold value are set. Is provided.
そして、第1の主光源15aの光が第1の所定値C1よりも小さい場合、第1の主光源15aの光の増加に準じて、第1の副光源16aの光を増減する。つまり、第1の主光源15aの光が増加して相関色温度が高くなるときには第1の副光源16aの光も増加し、第1の主光源15aの光が減少し相関色温度が低くなるときには第1の副光源16aの光も減少する。これにより、発光面13Dの端部領域13bが昼光色になっていくのに伴って発光面13Dの中央領域13aの青色感を強くし、青空のような演出効果が得られ、また、発光面13Dの端部領域13bが電球色になっていくのに伴って発光面13Dの中央領域13aの青色感を弱くし、夕焼け空のような演出効果を得ることができる。 When the light from the first main light source 15a is smaller than the first predetermined value C1, the light from the first sub light source 16a is increased or decreased according to the increase in the light from the first main light source 15a. That is, when the light of the first main light source 15a increases and the correlated color temperature increases, the light of the first sub light source 16a also increases, and the light of the first main light source 15a decreases and the correlated color temperature decreases. Sometimes, the light of the first sub light source 16a also decreases. Thereby, as the end region 13b of the light emitting surface 13D becomes daylight-colored, the blue feeling of the central region 13a of the light emitting surface 13D is strengthened, and an effect such as a blue sky is obtained, and the light emitting surface 13D As the end region 13b becomes light-bulb color, the blue feeling of the central region 13a of the light emitting surface 13D is weakened, and an effect like a sunset sky can be obtained.
さらに、第2の主光源15bの光が第2の所定値C2よりも小さい場合、第2の主光源15bの光の増加に準じて、第2の副光源16bの光を増減する。つまり、第2の主光源15bの光が増加して相関色温度が低くなるときには第2の副光源16bの光も増加し、第2の主光源15bの光が減少して相関色温度が高くなるときには第2の副光源16bの光も減少する。これにより、発光面13Dの端部領域13bが電球色になっていくのに伴って発光面13Dの中央領域13aの赤色感を強くし、日中から夕方にかけての空のような演出効果が得られ、また、発光面13Dの端部領域13bが昼光色になっていくのに伴って発光面13Dの中央領域13aの赤色感を弱くし、違和感を感じることがないようにすることができる。 Further, when the light of the second main light source 15b is smaller than the second predetermined value C2, the light of the second sub light source 16b is increased or decreased according to the increase of the light of the second main light source 15b. That is, when the light of the second main light source 15b increases and the correlated color temperature decreases, the light of the second auxiliary light source 16b also increases, and the light of the second main light source 15b decreases and the correlated color temperature increases. When this happens, the light of the second sub light source 16b also decreases. This enhances the red color of the central region 13a of the light emitting surface 13D as the end region 13b of the light emitting surface 13D becomes light-bulb-colored, and provides a sky-like effect from daytime to evening. In addition, as the end region 13b of the light emitting surface 13D becomes daylight-colored, the redness of the central region 13a of the light emitting surface 13D can be weakened so that the user does not feel uncomfortable.
また、第1の主光源15aの光が第1の所定値C1よりも大きい場合、第1の副光源16aの光の増減を、第1の主光源15aの光の増減に対して逆転させる。つまり、第1の主光源15aの光が増加して相関色温度が高くなるときには第1の副光源16aの光が減少し、第1の主光源15aの光が減少して相関色温度が低くなるときには第1の副光源16aの光が増加する。これにより、発光面13Dの端部領域13bが昼光色になっていくのに伴って、発光面13Dの中央領域13aの青くなり過ぎるのを防止し、演出効果が得られなくなるのを防止できる。 When the light of the first main light source 15a is larger than the first predetermined value C1, the increase or decrease of the light of the first sub light source 16a is reversed with respect to the increase or decrease of the light of the first main light source 15a. That is, when the light of the first main light source 15a increases and the correlated color temperature increases, the light of the first sub light source 16a decreases, and the light of the first main light source 15a decreases and the correlated color temperature decreases. When this happens, the light of the first sub light source 16a increases. Accordingly, it is possible to prevent the central region 13a of the light emitting surface 13D from becoming too blue as the end region 13b of the light emitting surface 13D becomes daylighting, thereby preventing the effect from being lost.
また、第2の主光源15bの光が第2の所定値C2よりも大きい場合、第2の副光源16bの光の増減を、第2の主光源15bの光の増減に対して逆転させる。つまり、第2の主光源15bの光が増加して相関色温度が低くなるときには第2の副光源16bの光が減少し、第2の主光源15bの光が減少して相関色温度が高くなるときには第2の副光源16bの光が増加する。これにより、発光面13Dの端部領域13bの電球色感が強くなったときには、発光面13Dの中央領域13aが赤くなり過ぎるのを防止し、違和感のない夕焼け空のような演出効果が得られるようにできる。 When the light of the second main light source 15b is larger than the second predetermined value C2, the increase or decrease of the light of the second sub light source 16b is reversed with respect to the increase or decrease of the light of the second main light source 15b. That is, when the light of the second main light source 15b increases and the correlated color temperature decreases, the light of the second sub light source 16b decreases, and the light of the second main light source 15b decreases and the correlated color temperature increases. When this happens, the light of the second sub light source 16b increases. Thereby, when the color of the bulb in the end region 13b of the light emitting surface 13D becomes strong, it is possible to prevent the central region 13a of the light emitting surface 13D from becoming too red, and it is possible to obtain an effect such as a sunset sky without a sense of discomfort. Can be.
