第１波長単色光取り出し部１０は、光源１１、スリット１２a、ミラー１３a、波長分散素子１４、ミラー１３b、スリット１２b、光ファイバ１５、レンズ１６、可変電源１７及び駆動手段１８などを有する。波長分散素子の例としては、回折格子やプリズム等が挙げられる。ここでは、波長分散素子１４として回折格子を用いることとする。また、ミラー１３a、１３b、及び後述するミラー２３a、２３bは使用する波長分散素子の種類や当該素子の配置によっては省略することができる。 The first wavelength monochromatic light extraction unit 10 includes a light source 11, a slit 12a, a mirror 13a, a wavelength dispersion element 14, a mirror 13b, a slit 12b, an optical fiber 15, a lens 16, a variable power source 17, a driving unit 18, and the like. Examples of wavelength dispersion elements include diffraction gratings and prisms. Here, a diffraction grating is used as the wavelength dispersion element 14. Further, the mirrors 13a and 13b and mirrors 23a and 23b described later can be omitted depending on the type of wavelength dispersion element used and the arrangement of the elements.
回折格子１４は回動することでミラー１３bに向けて反射する第１単色光の波長を変えることができる。回折格子１４には駆動手段１８が接続されており、該駆動手段１８により回折格子１４を回動させる。駆動手段１８は例えばステッピングモーターである。
すなわち、スリット１２aからスリット１２bの間の各素子がモノクロメータを構成することで、光源１１から第１単色光を取り出す。
The diffraction grating 14 can change the wavelength of the first monochromatic light reflected toward the mirror 13b by rotating. Driving means 18 is connected to the diffraction grating 14, and the diffraction grating 14 is rotated by the driving means 18. The driving means 18 is, for example, a stepping motor.
That is, each element between the slit 12a and the slit 12b constitutes a monochromator, so that the first monochromatic light is extracted from the light source 11.
第２波長単色光取り出し部２０も、第１波長単色光取り出し部１０と同様の構成であり、光源２１、スリット２２a、ミラー２３a、回折格子２４、ミラー２３b、スリット２２b、光ファイバ２５、レンズ２６、可変電源２７及び駆動手段２８を有する。光源２１にも、光源１１と同様にハロゲンランプ等を用いることができる。 The second wavelength monochromatic light extraction unit 20 has the same configuration as that of the first wavelength monochromatic light extraction unit 10, and includes a light source 21, a slit 22a, a mirror 23a, a diffraction grating 24, a mirror 23b, a slit 22b, an optical fiber 25, and a lens 26. And a variable power source 27 and a driving means 28. Similarly to the light source 11, a halogen lamp or the like can be used for the light source 21.
光源２１は可変電源２７に接続されており、可変電源２７は光源２１に供給する電力を制御することで、光源２１の光量を調整する。回折格子２４には駆動手段２８が接続されており、該駆動手段２８により回折格子２４を回動させる。 The light source 21 is connected to a variable power source 27, and the variable power source 27 controls the power supplied to the light source 21 to adjust the light amount of the light source 21. Driving means 28 is connected to the diffraction grating 24, and the diffraction grating 24 is rotated by the driving means 28.
取り出された第２単色光は、光ファイバ２５、レンズ２６を介し、第１単色光と同様に混色部３０に照射する。レンズ２６も、レンズ１６と同様に例えば凸型のレンズとするとよい。なお、光ファイバ２５及びレンズ２６はなくてもよい。また、第１波長単色光取り出し部１０についても、光ファイバ１５及びレンズ１６はなくても良い。 The extracted second monochromatic light is applied to the color mixing unit 30 through the optical fiber 25 and the lens 26 in the same manner as the first monochromatic light. Similarly to the lens 16, the lens 26 may be a convex lens, for example. Note that the optical fiber 25 and the lens 26 may be omitted. Further, the optical fiber 15 and the lens 16 may not be provided in the first wavelength monochromatic light extraction unit 10.
例えば、使用者がＰＣ制御部４０上で、第１単色光の波長を380nm、第２単色光の波長を780nmに設定すると、ＰＣ制御部４０が駆動手段１８及び駆動手段２８に制御信号を送る。駆動手段１８は送られた制御信号に基づいて回折格子１４を回動させて第１単色光の波長を380nmに設定し、駆動手段２８は送られた制御信号に基づいて回折格子２４を回動させて第２単色光の波長を780nmに設定する。これにより、第１単色光と第２単色光を混合して得られる色は、Ａ(380nm)とB(780nm)を結んだ直線上のいずれかの色となる。 For example, when the user sets the wavelength of the first monochromatic light to 380 nm and the wavelength of the second monochromatic light to 780 nm on the PC control unit 40, the PC control unit 40 sends a control signal to the driving unit 18 and the driving unit 28. . The driving means 18 rotates the diffraction grating 14 based on the sent control signal to set the wavelength of the first monochromatic light to 380 nm, and the driving means 28 turns the diffraction grating 24 based on the sent control signal. Thus, the wavelength of the second monochromatic light is set to 780 nm. As a result, the color obtained by mixing the first monochromatic light and the second monochromatic light is any color on a straight line connecting A (380 nm) and B (780 nm).
さらに、使用者がＰＣ制御部４０上で、第１単色光及び第２単色光の光量（或いはそれらの比率）を設定すると、ＰＣ制御部４０は可変電源１７及び可変電源２７に制御信号を送る。可変電源１７は送られた制御信号に基づいて光源１１に供給する電力を制御し、可変電源２７は送られた制御信号に基づいて光源２１に供給する電力を制御する。このようにして第１単色光と第２単色光の混合比率を変え、Ａ(380nm)とB(780nm)を結んだ直線上の任意の色を得る。第１単色光の混合比率を大きくすれば、直線上のＡに近い位置にある色が得られ、第２単色光の混合比率を大きくすれば、直線上のＢに近い位置にある色が得られる。 Further, when the user sets the light amounts (or their ratios) of the first monochromatic light and the second monochromatic light on the PC control unit 40, the PC control unit 40 sends control signals to the variable power source 17 and the variable power source 27. . The variable power source 17 controls the power supplied to the light source 11 based on the sent control signal, and the variable power source 27 controls the power supplied to the light source 21 based on the sent control signal. In this way, an arbitrary color on the straight line connecting A (380 nm) and B (780 nm) is obtained by changing the mixing ratio of the first monochromatic light and the second monochromatic light. If the mixing ratio of the first monochromatic light is increased, a color close to A on the straight line is obtained, and if the mixing ratio of the second monochromatic light is increased, a color close to B on the straight line is obtained. It is done.
また、使用者がＰＣ制御部４０上で、第１単色光の波長を(380+Δλ1)nm、第２単色光の波長を(780-Δλ2)nmに設定する（或いはΔλ1及びΔλ2の値を設定する）と、色度点Ａ、Ｂはそれぞれ、(380+Δλ1)nmと(780-Δλ2)nmの位置に移動する。この場合も、上記同様に第１単色光及び第２単色光の光量を変えることで、両色度点を結んだ直線上の任意の色が得られる。このようにして第１単色光及び第２単色光の波長及び光量を変えて行くことで、ＸＹ色度図上の所望の色を得る。
なお、波長が520nmの単色光の色度点は、スペクトル軌跡のほぼ頂点になるため、本実施例のように、520nmを境に第１単色光と第２単色光の波長を分けた構成とすることで、所望の色を得る際に、波長の第１単色光及び第２単色光の様々な組み合わせが可能となる。
Further, the user sets the wavelength of the first monochromatic light to (380 + Δλ1) nm and the wavelength of the second monochromatic light to (780−Δλ2) nm on the PC control unit 40 (or sets the values of Δλ1 and Δλ2). When set, the chromaticity points A and B move to the positions of (380 + Δλ1) nm and (780−Δλ2) nm, respectively. In this case as well, an arbitrary color on a straight line connecting both chromaticity points can be obtained by changing the light amounts of the first monochromatic light and the second monochromatic light as described above. In this way, a desired color on the XY chromaticity diagram is obtained by changing the wavelengths and light amounts of the first monochromatic light and the second monochromatic light.
Since the chromaticity point of monochromatic light having a wavelength of 520 nm is almost the apex of the spectrum locus, as in this embodiment, the wavelength of the first monochromatic light and the second monochromatic light are separated from each other at 520 nm. Thus, when obtaining a desired color, various combinations of the first monochromatic light and the second monochromatic light having a wavelength are possible.
上述のΔλ1とΔλ2は、同じ値（Δλ）とすることもできる。すなわち、使用者がＰＣ制御部４０上でΔλの値を設定するだけで、ＰＣ制御部４０は、第１単色光の波長を(380+Δλ)nmに、第２単色光の波長を(780-Δλ)nmとして、駆動手段１８及び駆動手段２８に制御信号を送る。こうすることで、使用者の操作負担を軽減できる。この場合、図５に示すように、色度点Ａ、Ｂはそれぞれ、(380+Δλ)nmと(780-Δλ)nmに位置し、両色度点を結んだ直線上の任意の色が得られる。第１単色光及び第２単色光の波長範囲としては、例えば、第１単色光を380nm〜580nmの波長範囲に、第２単色光を580〜780nmの波長範囲に設定できるようにするとよい。580nmは、380nmと780nmの中間の値である。 The above-described Δλ1 and Δλ2 may be the same value (Δλ). That is, only by the user setting the value of Δλ on the PC control unit 40, the PC control unit 40 sets the wavelength of the first monochromatic light to (380 + Δλ) nm and the wavelength of the second monochromatic light to (780 A control signal is sent to the drive means 18 and the drive means 28 as Δλ ) nm. By doing so, the operation burden on the user can be reduced. In this case, as shown in FIG. 5, the chromaticity points A and B are located at (380 + Δλ) nm and (780−Δλ) nm, respectively, and an arbitrary color on a straight line connecting both chromaticity points is can get. As a wavelength range of the first monochromatic light and the second monochromatic light, for example, the first monochromatic light may be set to a wavelength range of 380 nm to 580 nm, and the second monochromatic light may be set to a wavelength range of 580 to 780 nm. 580 nm is an intermediate value between 380 nm and 780 nm.
上記実施例では、第１波長単色光取り出し部１０と第２波長単色光取り出し部２０とで、異なる光源としたが、図７に示すように、光源を共通とすることもできる。この場合は、光源を挟んで両側に第１波長単色光取り出し部と第２波長単色光取り出し部を配置し、これら取り出し部のスリット１２a及びスリット２２aを同軸上に配置する。また、スリット１２bと光ファイバ７０、及びスリット２２bと光ファイバ７１の間にそれぞれ可変アテネータ１９及び２９を挿入し、各可変アテネータの減衰量をＰＣ制御部４０で制御できるようにするとよい。これにより、第１単色光と第２単色光の光量を個別に減衰させ、両単色光の混合比率を調整することが可能となる。光量調節のためにNDフィルタなどを用いてもよい。
このような構成とすることで、発光装置を小型化し、製造コストを下げることができる。
In the above embodiment, the first wavelength monochromatic light extraction unit 10 and the second wavelength monochromatic light extraction unit 20 have different light sources. However, as shown in FIG. 7, a common light source may be used. In this case, the first wavelength monochromatic light extraction unit and the second wavelength monochromatic light extraction unit are arranged on both sides of the light source, and the slit 12a and the slit 22a of these extraction units are arranged coaxially. Moreover, by inserting each variable attenuator 19 and 29 between the slits 12b and the optical fiber 70 and the slit 22b and the optical fiber 71, the attenuation amount of the variable attenuator may be able to control the PC control unit 40. Thereby, it is possible to individually attenuate the light amounts of the first monochromatic light and the second monochromatic light and adjust the mixing ratio of the monochromatic lights. An ND filter or the like may be used to adjust the light amount.
With such a structure, the light-emitting device can be downsized and the manufacturing cost can be reduced.
