　このとき、光源から光が放射されると、光源自体が発熱する。さらに、光源から放射された光を受けて反射傘も熱せられる。そのため、筐体内に熱が蓄積して、光源自体の温度の低下を阻害する。その結果、光照射装置の性能を十分に発揮することができない。そこで、筐体内に蓄積した熱を外部に放出する必要がある。 At this time, when light is emitted from the light source, the light source itself generates heat. Furthermore, the reflector is also heated by receiving light emitted from the light source. For this reason, heat accumulates in the housing and hinders a decrease in the temperature of the light source itself. As a result, the performance of the light irradiation device cannot be exhibited sufficiently. Therefore, it is necessary to release the heat accumulated in the housing to the outside.
　具体的には、上記光照射装置を光線治療器として用いる場合、光源に閃光放電管を用いて、連続発光させることがある。このとき、閃光放電管の連続発光する時間が長い場合や、連続発光の間欠時間が短い場合、反射傘に熱が蓄積され、反射傘が高温になる。これにより、筐体内が高温となる。そして、閃光放電管の温度が下がらないため、閃光放電管が点灯しにくくなる。そのため、閃光放電管を冷却するために動作禁止時間を設定するなどの対応が必要であった。その結果、使用者の利便性が低下するという課題があった。 Specifically, when the light irradiation device is used as a phototherapy device, a flash discharge tube may be used as a light source to cause continuous light emission. At this time, when the continuous light emission time of the flash discharge tube is long, or when the intermittent light emission intermittent time is short, heat is accumulated in the reflector and the reflector becomes high temperature. Thereby, the inside of a housing | casing becomes high temperature. And since the temperature of a flash discharge tube does not fall, it becomes difficult to light a flash discharge tube. Therefore, it is necessary to take measures such as setting an operation prohibition time in order to cool the flash discharge tube. As a result, there is a problem that convenience for the user is lowered.

　本発明は、筐体内の熱を効率的に筐体の外部に放出できる、光照射装置および光照射治療・予防装置を提供する。 The present invention provides a light irradiation device and a light irradiation treatment / prevention device that can efficiently release the heat in the case to the outside of the case.
　つまり、本発明は、光源と、光源から放射される放射光を被照射体に向けて反射する反射部と、光源を格納する筐体と、を備える光照射装置である。そして、反射部に接続される放熱部を備え、筐体は、内側と外側とを貫通する放出部を有する、外側に突出して設けられる膨出部を備える。さらに、膨出部は、内側で放熱部を収容する構成を有している。 That is, this invention is a light irradiation apparatus provided with a light source, a reflection part which reflects the emitted light radiated | emitted from a light source toward an to-be-irradiated body, and the housing | casing which stores a light source. And the heat dissipation part connected to a reflection part is provided, and a housing | casing is provided with the bulging part provided in the outer side which has the discharge | release part which penetrates an inner side and an outer side. Furthermore, the bulging part has a configuration for accommodating the heat radiating part inside.
　この構成によれば、膨出部が筐体の外側に突出して設けられ、放熱部を膨出部の内側に収容することにより、外部と熱交換しやすくなる。そのため、光源の発光に伴って反射部に蓄積される熱は、膨出部の内側と外側とを貫通する放出部を介して放熱部から外部に放出されやすくなる。これにより、筐体内の熱を効率的に筐体の外部に放出することができる。その結果、使用時における、閃光放電管の冷却時間を短縮できる高い効率の光照射装置を実現できる。 According to this configuration, the bulging portion is provided so as to protrude to the outside of the casing, and the heat radiating portion is accommodated inside the bulging portion, thereby facilitating heat exchange with the outside. For this reason, the heat accumulated in the reflecting portion as the light source emits light is likely to be released from the heat radiating portion to the outside through the emitting portion penetrating the inside and outside of the bulging portion. Thereby, the heat in the housing can be efficiently released to the outside of the housing. As a result, it is possible to realize a highly efficient light irradiation device that can shorten the cooling time of the flash discharge tube during use.
　また、本発明は、上記に記載の光照射装置から照射される光を生体の特定部位に照射することにより、治療または予防する光照射治療・予防装置である。そして、光源から放射される光の光路上に配置され、光源から放射される放射光のうち、波長が５６６．５ｎｍ以上７８０ｎｍ以下の範囲内の放射光を透過させる波長透過部を備える。さらに、波長透過部を透過させた透過光を生体の特定部位に照射可能な構成を有している。 Further, the present invention is a light irradiation treatment / prevention device that treats or prevents light by irradiating a specific part of a living body with light irradiated from the light irradiation device described above. And it is arrange | positioned on the optical path of the light radiated | emitted from a light source, and the wavelength transmission part which permeate | transmits the radiated light within the range whose wavelength is 566.5 nm or more and 780 nm or less among the radiated light radiated | emitted from a light source is provided. Furthermore, it has the structure which can irradiate the specific part of a biological body with the transmitted light which permeate | transmitted the wavelength transmission part.
　この構成によれば、上記の光照射装置の効果が得られる。 According to this configuration, the effect of the light irradiation device can be obtained.
　さらに、波長透過部を透過した５６６．５ｎｍ以上７８０ｎｍ以下の範囲内の波長は、炎症性サイトカインの産生を抑制する働きを有している。そのため、各種疾患（例えば、炎症や肌荒れなど）を予防したい部位または罹患した部位にこの波長の光を照射して、炎症性サイトカインの産生を抑制できる。これにより、例えば炎症性疾患に対して、罹患が予防されるとともに、罹患時の症状が軽減される。さらに、炎症性疾患を抑制することができる。 Furthermore, the wavelength within the range of 566.5 nm or more and 780 nm or less transmitted through the wavelength transmission part has a function of suppressing the production of inflammatory cytokines. Therefore, the production of inflammatory cytokines can be suppressed by irradiating light of this wavelength to a site where various diseases (for example, inflammation, rough skin, etc.) are to be prevented or affected. Thereby, for example, against inflammatory diseases, morbidity is prevented and symptoms at the time of illness are reduced. Furthermore, inflammatory diseases can be suppressed.

　（実施の形態）
　以下に、本発明の実施の形態に係る光照射装置および光照射治療・予防装置の構成について、図１から図４を参酌しながら説明する。 (Embodiment)
The configuration of the light irradiation device and the light irradiation treatment / prevention device according to the embodiment of the present invention will be described below with reference to FIGS.
　なお、本実施の形態の光照射治療・予防装置として、以下に示す被治療者を治療するために用いる光照射装置を例に説明する。具体的には、主に、炎症性疾患の罹患の予防、または罹患時の疾患の症状を軽減する予防治療を受ける被治療者、あるいは炎症性疾患を抑制する治療を受ける被治療者（患者）を治療する光照射装置である。 In addition, as a light irradiation treatment / prevention device according to the present embodiment, a light irradiation device used for treating a person to be treated shown below will be described as an example. Specifically, a subject who receives prevention treatment for prevention of inflammatory disease or a symptom of disease at the time of illness, or treatment subject who receives treatment for suppressing inflammatory disease (patient) It is a light irradiation device for treating.
　まず、本発明の実施の形態に係る光照射治療・予防装置の構成について、図１から図３を用いて説明する。 First, the configuration of the light irradiation treatment / prevention device according to the embodiment of the present invention will be described with reference to FIGS. 1 to 3.
　図１は、本発明の実施の形態に係る光照射治療・予防装置の外観図である。図２は、同実施の形態に係る光照射治療・予防装置の断面図である。図３は、同実施の形態に係る光照射治療・予防装置の光源ユニットと膨出部との分解斜視図である。 FIG. 1 is an external view of a light irradiation treatment / prevention device according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the light irradiation treatment / prevention device according to the embodiment. FIG. 3 is an exploded perspective view of the light source unit and the bulging portion of the light irradiation treatment / prevention device according to the embodiment.
　まず、図１および図２に示すように、本実施の形態の光照射治療・予防装置１は、筐体８と、筐体８に収容される、少なくとも光源ユニット１２と、反射部材３と、透過部材５などから構成されている。 First, as shown in FIGS. 1 and 2, the light irradiation treatment / prevention device 1 according to the present embodiment includes a housing 8, at least a light source unit 12, a reflecting member 3, and a housing 8. It is composed of a transmissive member 5 and the like.
　光源ユニット１２は、少なくとも光源２と、反射部を構成する反射傘１０と、波長透過部４と、フレネルレンズ１１と、熱伝導部６と、放熱部７と、発光制御部９などから構成されている。 The light source unit 12 includes at least a light source 2, a reflector 10 that constitutes a reflection unit, a wavelength transmission unit 4, a Fresnel lens 11, a heat conduction unit 6, a heat radiation unit 7, a light emission control unit 9, and the like. ing.
　そして、反射部材３は、光源２から放射される放射光を被照射体に向けて反射する。波長透過部４は、光源２から放射される放射光のうち、波長が特定の範囲内の放射光を透過させる。透過部材５は、波長透過部４を透過した光を被照射体に向けて透過させる。熱伝導部６は、反射部材３の一部に一体的に成形され、反射部から熱伝導した熱を放熱部７に伝熱する。放熱部７は、熱伝導部６に熱伝導された熱を放熱する。発光制御部９は、光源２の発光を制御する。 The reflecting member 3 reflects the radiation emitted from the light source 2 toward the irradiated object. The wavelength transmission unit 4 transmits the radiated light having a wavelength within a specific range among the radiated light emitted from the light source 2. The transmission member 5 transmits the light transmitted through the wavelength transmission unit 4 toward the irradiated body. The heat conducting unit 6 is formed integrally with a part of the reflecting member 3, and transfers heat conducted from the reflecting unit to the heat radiating unit 7. The heat radiating unit 7 radiates the heat conducted to the heat conducting unit 6. The light emission control unit 9 controls light emission of the light source 2.
　また、反射部を構成する反射傘１０は、光源２から放射される放射光を一方に向けて反射する。フレネルレンズ１１は、反射傘１０の開口部に取り付けられ、波長透過部４に向けて入射する光の入射角度を整合する。 Also, the reflector 10 constituting the reflection part reflects the radiated light emitted from the light source 2 toward one side. The Fresnel lens 11 is attached to the opening of the reflector 10 and matches the incident angle of the light incident toward the wavelength transmission unit 4.
　また、光源２は、例えばキセノン放電管やハロゲン放電管などの閃光放電管などで構成され、生体の予防したい部位または罹患した部位に、炎症性サイトカインの産生を抑制する波長の放射光を照射する。なお、本実施の形態では、光源２として、キセノン放電管を用いた場合を例に説明する。 The light source 2 is composed of, for example, a flash discharge tube such as a xenon discharge tube or a halogen discharge tube, and irradiates a portion of the living body that is desired to be prevented or affected with radiation having a wavelength that suppresses the production of inflammatory cytokines. . In the present embodiment, a case where a xenon discharge tube is used as the light source 2 will be described as an example.
　このとき、光源２は、図２に示すように、透過部材５の第１の透過面１３に接する直線Ａ（図中の１点鎖線で示す）より下側で、光照射部２１に載置される被照射体側に配置されている。なお、光源２を透過部材５の第１の透過面１３に接する直線Ａより被照射体側に配置する理由は、光源２から放射される放射光のうち、透過部材５の第１の透過面１３に直接入射する光が、第１の透過面１３に直接入射することを防止するためである。直接光の一部が第１の透過面１３に入射することを無視できる、もしくは考慮する必要がなく、さらに、一部の直接光が第１の透過面１３に入射し、残りの直接光が入射しない場合であれば、直線Ａより上側で被照射体側と反対側に、光源２を配置してもよいことはいうまでもない。つまり、上記の場合も、本実施の形態で説明する「光源２は、透過部材５の第１の透過面１３に接する直線Ａより被照射体側に配置される」という意味に含めて解釈する。 At this time, as shown in FIG. 2, the light source 2 is placed on the light irradiation unit 21 below the straight line A (indicated by a one-dot chain line in the drawing) in contact with the first transmission surface 13 of the transmission member 5. It is arranged on the irradiated object side. The reason why the light source 2 is arranged closer to the irradiated body than the straight line A in contact with the first transmission surface 13 of the transmission member 5 is that the first transmission surface 13 of the transmission member 5 out of the radiated light emitted from the light source 2. This is to prevent light that is directly incident on the first transmitting surface 13 from directly entering. It is negligible or need not consider that a part of the direct light is incident on the first transmission surface 13, and a part of the direct light is incident on the first transmission surface 13, and the remaining direct light is Needless to say, if it is not incident, the light source 2 may be arranged above the straight line A and on the opposite side of the irradiated body. That is, the above case is also interpreted in the meaning of “the light source 2 is arranged on the irradiated object side with respect to the straight line A in contact with the first transmission surface 13 of the transmission member 5” described in the present embodiment.
　また、図２に示すように、光源ユニット１２の反射傘１０は、少なくとも第１反射部１５と、第２反射部１６とを備えている。第１反射部１５は、透過部材５の第１の透過面１３に接する直線Ａより透過部材５の被照射体側と反対側（ケーシング２２側）に向かう放射光を透過部材５に反射する。第２反射部１６は、直線Ａより被照射体側に向かう放射光を第１反射部１５に反射する。このとき、第１反射部１５は、透過部材５の第１の透過面１３に面する（対向する）ように配置される。一方、第２反射部１６は、透過部材５の第１の透過面１３に面しない（対向しない）ように配置され、第１反射部１５に面する（対向する）ように配置される。 Further, as shown in FIG. 2, the reflector 10 of the light source unit 12 includes at least a first reflector 15 and a second reflector 16. The first reflecting portion 15 reflects the radiated light directed to the opposite side (casing 22 side) of the transmissive member 5 from the straight line A in contact with the first transmissive surface 13 of the transmissive member 5 to the transmissive member 5. The second reflecting portion 16 reflects the radiated light traveling from the straight line A toward the irradiated body side to the first reflecting portion 15. At this time, the first reflection portion 15 is disposed so as to face (oppose) the first transmission surface 13 of the transmission member 5. On the other hand, the second reflecting portion 16 is arranged so as not to face (does not face) the first transmissive surface 13 of the transmissive member 5 and is arranged so as to face (facing) the first reflecting portion 15.
　さらに、反射傘１０の第１反射部１５および第２反射部１６は、被照射体に向けて放射光を反射する反射面を有している。反射面は、可視光を反射して赤外線を透過する光学多層膜と、赤外線を吸収する赤外線吸収層とが形成されて構成されている。なお、本実施の形態の赤外線吸収層は、着色アルマイト層から構成されている例で説明する。 Furthermore, the first reflecting portion 15 and the second reflecting portion 16 of the reflector 10 have a reflecting surface that reflects the emitted light toward the irradiated object. The reflection surface is formed by forming an optical multilayer film that reflects visible light and transmits infrared light, and an infrared absorption layer that absorbs infrared light. In addition, the infrared rays absorption layer of this Embodiment demonstrates by the example comprised from the coloring alumite layer.
　以下に、上記反射傘１０を構成する第１反射部１５および第２反射部１６の動作・作用について、説明する。 Hereinafter, the operation and action of the first reflecting portion 15 and the second reflecting portion 16 constituting the reflector 10 will be described.
　つまり、第１反射部１５および第２反射部１６の反射面の光学多層膜は、光源２から放射される放射光に含まれる可視光を被照射体側に反射し、放射光に含まれる赤外線を赤外線吸収層に透過する。そして、光学多層膜を透過した赤外線は、赤外線吸収層で吸収される。これにより、光源２の発光により発生する熱を、高い効率で第１反射部１５および第２反射部１６の反射面の赤外線吸収層で吸収して熱伝導部６を介して放熱部７に熱伝導する。その結果、光源２により発生した熱を、放熱部７から筐体８の外部に効率的に放出できる。 That is, the optical multilayer film on the reflecting surfaces of the first reflecting portion 15 and the second reflecting portion 16 reflects visible light included in the radiated light emitted from the light source 2 toward the irradiated object side, and reflects infrared light included in the radiated light. Transmits to the infrared absorbing layer. And the infrared rays which permeate | transmitted the optical multilayer film are absorbed in an infrared rays absorption layer. Thereby, the heat generated by the light emission of the light source 2 is absorbed by the infrared absorption layers on the reflection surfaces of the first reflection unit 15 and the second reflection unit 16 with high efficiency, and heat is transferred to the heat dissipation unit 7 via the heat conduction unit 6. Conduct. As a result, the heat generated by the light source 2 can be efficiently released from the heat radiating unit 7 to the outside of the housing 8.
　また、図２に示すように、フレネルレンズ１１は、例えば波長透過部４が入射角依存性を有するフィルタを用いる場合に設けられる。このとき、フレネルレンズ１１は、光源２から入射される入射角度が使用する波長透過部４の許容可能な角度以内となるように調整する。なお、波長透過部４に、例えば入射角依存性がない色ガラスフィルタなどを用いる場合、フレネルレンズ１１を省略してもよい。 Further, as shown in FIG. 2, the Fresnel lens 11 is provided, for example, when the wavelength transmission unit 4 uses a filter having an incident angle dependency. At this time, the Fresnel lens 11 is adjusted so that the incident angle incident from the light source 2 is within an allowable angle of the wavelength transmission unit 4 used. Note that the Fresnel lens 11 may be omitted when, for example, a colored glass filter having no incident angle dependency is used for the wavelength transmission unit 4.
　また、図２に示すように、熱伝導部６は、例えばアルミニウムまたはアルミニウム合金などの熱伝導可能な材料で成形され、反射傘１０から後述する放出部２４までの筐体８内の経路に沿った形状に連続して成形することにより設けられている。熱伝導部６の一端側は、反射傘１０の第１反射部１５と第２反射部１６とに一体的に成形されている。つまり、熱伝導部６の一端側に、反射傘１０の第１反射部１５および第２反射部１６の曲面形状の内面を有する、例えば断面視Ｕの字状の穴を成形して反射部を設けている。一方、熱伝導部６の他端側には、放熱部７が設けられる。 Further, as shown in FIG. 2, the heat conducting portion 6 is formed of a heat conductive material such as aluminum or an aluminum alloy, and follows a path in the housing 8 from the reflector 10 to the discharge portion 24 described later. It is provided by continuously forming into a different shape. One end side of the heat conducting unit 6 is integrally formed with the first reflecting unit 15 and the second reflecting unit 16 of the reflector 10. In other words, on the one end side of the heat conducting unit 6, the first reflecting unit 15 and the second reflecting unit 16 of the reflector 10 have curved inner surfaces, for example, a U-shaped hole in cross-sectional view is formed to form the reflecting unit. Provided. On the other hand, a heat radiating portion 7 is provided on the other end side of the heat conducting portion 6.
　このとき、熱伝導部６は、第１反射部１５に近い部分の方が第２反射部１６に近い部分より体積が大きくなるように成形している。これにより、熱伝導部６の他端側に熱伝導する熱伝導容量を大きくしている。 At this time, the heat conducting portion 6 is shaped such that the portion closer to the first reflecting portion 15 has a larger volume than the portion closer to the second reflecting portion 16. Thereby, the heat conduction capacity for conducting heat to the other end side of the heat conducting portion 6 is increased.
　また、図３に示すように、熱伝導部６は、第１反射部１５および第２反射部１６の内側に光源２を配置するために、光源２を挿入可能な挿入孔１７を設けている。 As shown in FIG. 3, the heat conducting unit 6 is provided with an insertion hole 17 into which the light source 2 can be inserted in order to arrange the light source 2 inside the first reflecting unit 15 and the second reflecting unit 16. .
　また、図３に示すように、放熱部７は、例えば一定の間隔を開けて熱伝導部６に一体に成形された複数のフィンから構成されている。放熱部７のフィンは、例えば上下方向に長い直方体形状で形成されている。これにより、各フィンの間に、空気が流れる流路７ａが上下方向に形成される。なお、フィンの形状は、上記長方体形状に限定されず、棒状でもよく、さらに上下方向でなく左右方向に長い直方体形状で設けてもよい。 Further, as shown in FIG. 3, the heat radiating portion 7 is composed of a plurality of fins that are integrally formed with the heat conducting portion 6 with a predetermined interval, for example. The fins of the heat radiating portion 7 are formed in a rectangular parallelepiped shape that is long in the vertical direction, for example. Thereby, the flow path 7a through which air flows is formed between the fins in the vertical direction. The shape of the fin is not limited to the above rectangular shape, and may be a rod shape, and may be a rectangular parallelepiped shape that is long in the left-right direction instead of the vertical direction.
　また、図２に示すように、反射部材３は、上述の光源ユニット１２の第１反射部１５および第２反射部１６と、第３反射部１８と、第４反射部１９と、第５反射部２０とから構成されている。第３反射部１８は、光源２から放射された放射光を、透過部材５の第１の透過面１３に反射する。第４反射部１９および第５反射部２０は、光源２から放射された放射光を、透過部材５の第１の透過面１３と対向する第２の透過面１４に反射する。これにより、透過部材５を透過して、放射光を光照射部２１に載置される被照射体に照射する。 As shown in FIG. 2, the reflecting member 3 includes the first reflecting portion 15 and the second reflecting portion 16, the third reflecting portion 18, the fourth reflecting portion 19, and the fifth reflecting portion of the light source unit 12 described above. Part 20. The third reflection unit 18 reflects the radiated light emitted from the light source 2 to the first transmission surface 13 of the transmission member 5. The fourth reflecting portion 19 and the fifth reflecting portion 20 reflect the radiated light emitted from the light source 2 to the second transmitting surface 14 facing the first transmitting surface 13 of the transmitting member 5. Thereby, the transmission member 5 is transmitted, and the irradiated object is irradiated with the emitted light placed on the light irradiation unit 21.
　また、波長透過部４は、光源２から放射された、１以上の特定の波長範囲、または１以上の特定範囲の波長の放射光のみを透過する光学フィルタで構成されている。 Further, the wavelength transmission unit 4 is configured by an optical filter that transmits only one or more specific wavelength ranges emitted from the light source 2 or one or more specific wavelengths of emitted light.
　そして、図２に示すように、波長透過部４は、光源２から放射されて透過部材５を透過する光の光路上に配置される。 As shown in FIG. 2, the wavelength transmission unit 4 is disposed on the optical path of the light emitted from the light source 2 and transmitted through the transmission member 5.
　以下に、本実施の形態の波長透過部４の光学フィルタとして、特定の波長範囲（波長帯）の放射光のみを選択的に透過するバンドパスフィルタ（干渉フィルタ）を例に、図４を用いて説明する。 FIG. 4 is used as an example of a bandpass filter (interference filter) that selectively transmits only radiated light in a specific wavelength range (wavelength band) as an optical filter of the wavelength transmission unit 4 of the present embodiment. I will explain.
　図４は、同実施の形態に係る光照射治療・予防装置に用いたバンドパスフィルタの透過光の分光特性を示すグラフである。 FIG. 4 is a graph showing the spectral characteristics of the transmitted light of the bandpass filter used in the light irradiation treatment / prevention device according to the embodiment.
　具体的には、図４に示すように、波長透過部４は、光源２から放射される放射光のうち、波長が５６６．５ｎｍ以上７８０ｎｍ以下の範囲内の放射光を透過させるバンドパスフィルタで構成される。 Specifically, as shown in FIG. 4, the wavelength transmission unit 4 is a band-pass filter that transmits radiated light having a wavelength in the range of 566.5 nm to 780 nm among radiated light emitted from the light source 2. Composed.
　このとき、上記の波長の範囲外の放射光は、波長透過部４に吸収、または反射などにより、光源ユニット１２に熱的な影響を与える。つまり、結果的に熱に変換されて、光源ユニット１２の熱伝導部６に熱伝導される。 At this time, the radiated light outside the above wavelength range has a thermal effect on the light source unit 12 by being absorbed or reflected by the wavelength transmitting portion 4. That is, as a result, it is converted into heat and is conducted to the heat conducting unit 6 of the light source unit 12.
　また、図４に示すように、各バンドパスフィルタを透過した透過光の分光特性（分光透過率）の波長範囲の下限値は、実線Ｃで示す中心波長６００ｎｍのバンドパスフィルタＣを透過する透過光の透過率が最大となる波長（実線Ｃ上のｂ点に対応する波長５６６．５ｎｍ）の透過率の２分の１（半分）となる短波長側の波長（実線Ｃ上のａ点に対応する波長）である。一方、各バンドパスフィルタを透過した透過光の分光特性（分光透過率）の波長範囲の上限値は、可視光の最大波長７８０ｎｍである。 Also, as shown in FIG. 4, the lower limit value of the wavelength range of the spectral characteristics (spectral transmittance) of the transmitted light that has passed through each bandpass filter is the transmission that passes through the bandpass filter C having a center wavelength of 600 nm indicated by the solid line C. Wavelength on the short wavelength side (at point a on the solid line C) that is half (half) the transmittance of the wavelength at which the light transmittance is maximum (wavelength 566.5 nm corresponding to the point b on the solid line C) Corresponding wavelength). On the other hand, the upper limit of the wavelength range of the spectral characteristics (spectral transmittance) of the transmitted light that has passed through each bandpass filter is the maximum wavelength of visible light of 780 nm.
　つまり、図４に示すように、放射光の中心波長６００ｎｍを有するバンドパスフィルタＣは、ｈＶＥＧＦ（血管内皮細胞増殖因子）の産生量を抑制する働きがある波長を透過させる光学フィルタである。なお、バンドパスフィルタＣより短波長側の、図４の実線Ｂで示す中心波長５００ｎｍのバンドパスフィルタＢは、ｈＶＥＧＦの産生量を抑制する効果が低いと考えられる。これにより、中心波長６００ｎｍのバンドパスフィルタＣの短波長側のａ点の波長が、炎症性サイトカインを抑制する働きがある下限値であると評価できる。 That is, as shown in FIG. 4, the bandpass filter C having a center wavelength of the emitted light of 600 nm is an optical filter that transmits a wavelength that functions to suppress the production amount of hVEGF (vascular endothelial growth factor). Note that the bandpass filter B having a center wavelength of 500 nm shown by the solid line B in FIG. 4 on the shorter wavelength side than the bandpass filter C is considered to be less effective in suppressing the amount of hVEGF produced. Thereby, it can be evaluated that the wavelength of the point a on the short wavelength side of the bandpass filter C having a center wavelength of 600 nm is a lower limit value that has a function of suppressing inflammatory cytokines.
　一方、図４に示す近赤外線（波長７８０ｎｍ超）の放射光は、使用者に照射する際に熱的な影響が大きい。そのため、近赤外線に至る可視光線（波長７８０ｎｍ以下）までの波長範囲を、波長透過部４が透過させる上限値としている。 On the other hand, the near-infrared (wavelength of more than 780 nm) radiation shown in FIG. Therefore, the wavelength range up to visible light (wavelength of 780 nm or less) reaching near infrared is set as an upper limit value that allows the wavelength transmission unit 4 to transmit.
　また、図２に示すように、透過部材５は、上述したように、少なくとも第１の透過面１３と第２の透過面１４の２つを備えている。そして、透過部材５は、波長透過部４を透過した透過光を透過させて、生体の特定部位に照射する。具体的には、透過部材５の第１の透過面１３を介して、生体の特定部位を上方から放射光を照射する。一方、透過部材５の第２の透過面１４を介して、生体の特定部位を下方から放射光を照射する。 Further, as shown in FIG. 2, the transmission member 5 includes at least two of the first transmission surface 13 and the second transmission surface 14 as described above. The transmitting member 5 transmits the transmitted light that has passed through the wavelength transmitting unit 4 and irradiates a specific part of the living body. Specifically, the specific part of the living body is irradiated with the emitted light from above via the first transmission surface 13 of the transmission member 5. On the other hand, the specific part of the living body is irradiated with the emitted light from below via the second transmission surface 14 of the transmission member 5.
　また、筐体８は、図１および図２に示すように、少なくとも光照射部２１と、ケーシング２２と、膨出部２３とを有している。光照射部２１は、透過部材５を構成する第１の透過面１３および第２の透過面１４が対向して配置することにより形成されている。そして、光照射部２１の間に挿入された生体の特定部位に上下方向から放射光を照射する。ケーシング２２は、光照射部２１を覆う。膨出部２３は、ケーシング２２の光源ユニット１２側の外側に、例えば凸状に突出して設けられている。 Further, as shown in FIGS. 1 and 2, the housing 8 has at least a light irradiation part 21, a casing 22, and a bulging part 23. The light irradiation unit 21 is formed by arranging the first transmission surface 13 and the second transmission surface 14 constituting the transmission member 5 to face each other. And the radiation | emission light is irradiated to the specific site | part of the biological body inserted between the light irradiation parts 21 from an up-down direction. The casing 22 covers the light irradiation unit 21. The bulging portion 23 is provided on the outer side of the casing 22 on the light source unit 12 side so as to protrude, for example, in a convex shape.
　具体的には、膨出部２３は、ケーシング２２から外側に向かって直方体形状に膨出して設けられている。そして、膨出部２３は、放熱部７との間に一定の隙間２３ａが形成される大きさを有し、その内側で放熱部７を収容する。これにより、膨出部２３の内面と放熱部７との間の隙間２３ａで、空気が流れる流路を形成している。 Specifically, the bulging portion 23 is provided so as to bulge from the casing 22 toward the outside in a rectangular parallelepiped shape. And the bulging part 23 has a magnitude | size in which the fixed clearance gap 23a is formed between the thermal radiation parts 7, and accommodates the thermal radiation part 7 inside it. Thereby, the flow path through which air flows is formed in the gap 23 a between the inner surface of the bulging portion 23 and the heat radiating portion 7.
　さらに、図２および図３に示すように、膨出部２３は、熱を外部に放出する放出部２４を有する。放出部２４は、放熱部７のフィンに対向して配置され、膨出部２３の内側と外側とを貫通する第１の窓２５および第２の窓２６から構成されている。第１の窓２５は、ケーシング２２の背面側における膨出部２３の面２３ｂに複数設けられ、筐体８の内部の空気を外部に排気する排気窓として機能する。第２の窓２６は、ケーシング２２の背面側における膨出部２３の面２３ｃに複数設けられ、筐体８の外部の空気を内部に吸気する吸気窓として機能する。これにより、放熱部７に熱伝導した熱を、効率的に筐体８の外部に放出する。 Furthermore, as shown in FIG. 2 and FIG. 3, the bulging part 23 has a discharge part 24 for releasing heat to the outside. The discharge part 24 is arranged to face the fins of the heat radiating part 7, and includes a first window 25 and a second window 26 that penetrate the inside and the outside of the bulging part 23. A plurality of first windows 25 are provided on the surface 23 b of the bulging portion 23 on the back side of the casing 22, and function as exhaust windows that exhaust the air inside the housing 8 to the outside. A plurality of second windows 26 are provided on the surface 23 c of the bulging portion 23 on the back side of the casing 22, and function as an intake window that sucks air outside the housing 8 into the interior. Thereby, the heat conducted to the heat radiating portion 7 is efficiently released to the outside of the housing 8.
　また、図２に示すように、発光制御部９は、光源２の発光条件の設定を受け付ける。そして、発光制御部９は、受け付けた発光条件に基づいて、光源２を制御して発光させる。 Further, as shown in FIG. 2, the light emission control unit 9 accepts the setting of the light emission conditions of the light source 2. Then, the light emission control unit 9 controls the light source 2 to emit light based on the received light emission condition.
　以上により、本実施の形態の光照射治療・予防装置が構成されている。 Thus, the light irradiation treatment / prevention device of the present embodiment is configured.
　以下に、本発明の実施形態に係る光照射治療・予防装置１の操作方法および動作について、説明する。 The operation method and operation of the light irradiation treatment / prevention device 1 according to the embodiment of the present invention will be described below.
　まず、手などの生体の特定部位を光照射部２１に挿入する。そして、発光スイッチ（図示せず）を押すと、光源２が発光する。 First, a specific part of a living body such as a hand is inserted into the light irradiation unit 21. When a light emission switch (not shown) is pressed, the light source 2 emits light.
　光源２から放射された放射光は、反射傘１０の第１反射部１５および第２反射部１６で、反射部材３に向かって反射される。そして、反射部材３の第３反射部１８で反射された放射光は、透過部材５の第１の透過面１３を透過して、特定部位の上方に照射される。一方、反射部材３の第４反射部１９および第５反射部２０で反射された放射光は、透過部材５の第２の透過面１４を透過して、特定部位の下方に照射される。これにより、生体の特定部位の炎症性疾患を、治療または予防することができる。 The radiated light emitted from the light source 2 is reflected toward the reflecting member 3 by the first reflecting portion 15 and the second reflecting portion 16 of the reflector 10. And the radiated light reflected by the 3rd reflection part 18 of the reflection member 3 permeate | transmits the 1st permeation | transmission surface 13 of the permeation | transmission member 5, and is irradiated above a specific site | part. On the other hand, the radiated light reflected by the fourth reflecting part 19 and the fifth reflecting part 20 of the reflecting member 3 passes through the second transmitting surface 14 of the transmitting member 5 and is irradiated below the specific part. Thereby, the inflammatory disease of the specific site | part of a biological body can be treated or prevented.
　このとき、光源２の発光にともない、反射傘１０（反射部）の赤外線吸収層で吸収され蓄積される熱は、反射傘１０に一体的に成形された熱伝導部６に熱伝導して、放熱部７から放熱される。なお、放熱部７は、筐体８の後方で外側に突出して設けられた膨出部２３の内側に収容されている。また、放熱部７は、複数のフィンで構成することにより、外部と熱交換する面積が広くなっている。さらに、放出部２４の第１の窓２５および第２の窓２６を介して、放熱部７に熱伝導してきた熱を放熱部７から外部に放出しやすくなっている。その結果、筐体８内に光源２をどの位置に配置しても、反射傘１０、熱伝導部６、放熱部７および放出部２４を介して、効率的に筐体８の外部に熱を放出できる。これにより、使用時における、閃光放電管の冷却時間を短縮して、効率的に治療や予防を行うことができる光照射装置および光照射治療・予防装置を実現できる。 At this time, as the light source 2 emits light, the heat absorbed and accumulated in the infrared absorbing layer of the reflector 10 (reflecting part) is conducted to the heat conducting part 6 formed integrally with the reflector 10, Heat is radiated from the heat radiating section 7. Note that the heat radiating portion 7 is accommodated inside a bulging portion 23 that protrudes outwardly behind the housing 8. Moreover, the heat radiating part 7 is composed of a plurality of fins, so that the area for heat exchange with the outside is widened. Furthermore, the heat that has been thermally conducted to the heat radiating portion 7 is easily released from the heat radiating portion 7 to the outside through the first window 25 and the second window 26 of the discharge portion 24. As a result, no matter where the light source 2 is arranged in the housing 8, heat is efficiently transferred to the outside of the housing 8 via the reflector 10, the heat conducting unit 6, the heat radiating unit 7, and the emitting unit 24. Can be released. Thus, it is possible to realize a light irradiation apparatus and a light irradiation treatment / prevention apparatus that can efficiently perform treatment and prevention by shortening the cooling time of the flash discharge tube during use.
　また、上述したように、本実施の形態の反射傘１０は、熱伝導部６の一端側に、反射傘１０の第１反射部１５および第２反射部１６の曲面形状の内面を有する、例えば断面視Ｕの字状の穴を一体成形して反射部を設けている。そのため、従来のように板材を折り曲げて断面視Ｕの字状に形成した反射傘と比較して、高い加工精度と、高い剛性により、反射部の反射曲面形状の精度を向上させることができる。その結果、特に、精密な反射曲面が求められる反射傘１０が要望される光照射装置に適している。 Further, as described above, the reflector 10 according to the present embodiment has the curved inner surfaces of the first reflector 15 and the second reflector 16 of the reflector 10 on one end side of the heat conducting part 6, for example, A reflective portion is provided by integrally forming a U-shaped hole in cross-sectional view. Therefore, compared with the reflector umbrella which bent the board | plate material conventionally and was formed in the cross-sectional view U-shape, the precision of the reflective curved surface shape of a reflection part can be improved with high process precision and high rigidity. As a result, the reflector 10 is particularly suitable for a light irradiation device that requires a precise reflecting curved surface.
　また、本実施の形態の光照射装置を備える光照射治療・予防装置は、各種疾患（例えば、炎症や肌荒れなど）を予防したい部位または罹患した部位に波長透過部４を透過した透過光を照射することにより、炎症性サイトカインの産生を抑制できる。その結果、炎症性サイトカインの産生が抑制して、例えば炎症性疾患の罹患を予防するとともに、罹患時の症状を軽減または抑制できる。 In addition, the light irradiation treatment / prevention device provided with the light irradiation device according to the present embodiment irradiates a site where various diseases (for example, inflammation, rough skin, etc.) are to be prevented or an affected site with transmitted light transmitted through the wavelength transmission unit 4. By doing so, the production of inflammatory cytokines can be suppressed. As a result, production of inflammatory cytokines can be suppressed, and for example, morbidity of inflammatory diseases can be prevented, and symptoms at the time of morbidity can be reduced or suppressed.
　なお、本発明の光照射装置および光照射治療・予防装置は、上記実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることはいうまでもない。 The light irradiation device and the light irradiation treatment / prevention device of the present invention are not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the scope of the present invention. .
　例えば、上記実施形態の光照射装置および光照射治療・予防装置１では、光源２から放射された放射光を手に照射する例で説明したが、これに限られない。例えば、炎症性サイトカインの産生の抑制を予防したい他の生体の部位または罹患した他の生体の部位に照射するようにしてもよい。具体的には、照射する生体の部位としては、肩や腰、足、全身など、どのような場所に照射してもよい。さらに、人間に照射する場合に限られず、人間以外の動物などの生体の特定部位に対し、治療のために光を照射してもよい。これらの場合は、本実施の形態に係る光照射治療・予防装置１の構造に限定されず、適宜、照射する生体の特定部位に適した構造に変更してもよいことはいうまでもない。 For example, in the light irradiation device and the light irradiation treatment / prevention device 1 of the above-described embodiment, the example in which the hand is irradiated with the radiated light emitted from the light source 2 has been described, but the present invention is not limited thereto. For example, irradiation may be performed on a part of another living body that is desired to prevent the suppression of the production of inflammatory cytokines or a part of another living body that is affected. Specifically, irradiation may be performed on any part of the living body such as a shoulder, a waist, a foot, or the whole body. Furthermore, the present invention is not limited to the case of irradiating a person, and a specific part of a living body such as an animal other than a human may be irradiated for treatment. In these cases, it is needless to say that the structure is not limited to the structure of the light irradiation treatment / prevention device 1 according to the present embodiment, and may be appropriately changed to a structure suitable for a specific part of a living body to be irradiated.
　また、上記実施の形態の光照射装置および光照射治療・予防装置１では、炎症性サイトカインの産生の抑制を予防したい生体の部位または罹患した生体の部位に照射する例で説明したが、これに限られない。例えば、他の用途に用いられる光照射装置に適用されてもよい。これにより、汎用性を向上できる。 Further, in the light irradiation device and the light irradiation treatment / prevention device 1 of the above-described embodiment, an example has been described in which irradiation is performed on a part of a living body that is desired to prevent suppression of the production of inflammatory cytokines or a part of a living body. Not limited. For example, you may apply to the light irradiation apparatus used for another use. Thereby, versatility can be improved.
　また、上記実施の形態の光照射装置および光照射治療・予防装置１では、熱伝導部６が第１反射部１５と第２反射部１６とからなる反射部と一体成形されている例で説明したが、これに限られない。例えば、熱伝導部２７を、以下で図５を用いて説明するように、反射傘１０の第１反射部１５のみに一体に成形してもよい。 Further, in the light irradiation device and the light irradiation treatment / prevention device 1 according to the above-described embodiment, an example in which the heat conducting unit 6 is integrally formed with a reflecting unit including the first reflecting unit 15 and the second reflecting unit 16 will be described. However, it is not limited to this. For example, the heat conducting portion 27 may be integrally formed only on the first reflecting portion 15 of the reflector 10 as described below with reference to FIG.
　以下に、本実施の形態の光照射装置および光照射治療・予防装置に用いられる反射傘の別の構成について、図５を用いて、具体的に説明する。 Hereinafter, another configuration of the reflector used in the light irradiation apparatus and the light irradiation treatment / prevention apparatus according to the present embodiment will be specifically described with reference to FIG.
　図５は、同実施の形態に係る光照射治療・予防装置の別の構成を説明する後部の拡大断面図である。 FIG. 5 is an enlarged cross-sectional view of a rear portion for explaining another configuration of the light irradiation treatment / prevention device according to the embodiment.
　図５に示すように、熱伝導部２７は、反射傘１０の第１反射部１５と一体成形により構成し、反射傘１０の第２反射部１６と別体として、両方を組み合わせて反射部を構成する。 As shown in FIG. 5, the heat conducting portion 27 is formed by integral molding with the first reflecting portion 15 of the reflecting umbrella 10, and as a separate body from the second reflecting portion 16 of the reflecting umbrella 10, both are combined to form the reflecting portion. Constitute.
　反射部を別体で構成する理由について、以下に説明する。 The reason why the reflection part is configured separately will be described below.
　第１反射部１５は、第２反射部１６から誘導される放射光と、光源２から直接放射される放射光の両方の放射光が反射される。そのため、第１反射部１５は、放射光の熱的影響をより受けて、第２反射部１６と比較して、高温になりやすい。しかし、上記構成の場合、熱伝導部２７は、第１反射部１５と一体に成形することにより、第２反射部１６からよりも、第１反射部１５から熱を熱伝導しやすい。これにより、より高温になりやすい第１反射部１５の熱を、第２反射部１６の熱より優先的に筐体８の外部に放出できる。その結果、筐体８内の熱を効率的に筐体８の外部に放出することができる。 The first reflecting portion 15 reflects both the emitted light guided from the second reflecting portion 16 and the emitted light directly emitted from the light source 2. For this reason, the first reflecting portion 15 is more susceptible to the thermal influence of the radiated light and is likely to be hotter than the second reflecting portion 16. However, in the case of the above configuration, the heat conducting portion 27 is formed integrally with the first reflecting portion 15, so that heat is more easily conducted from the first reflecting portion 15 than from the second reflecting portion 16. As a result, the heat of the first reflecting portion 15 that tends to be higher in temperature can be released to the outside of the housing 8 with priority over the heat of the second reflecting portion 16. As a result, the heat in the housing 8 can be efficiently released to the outside of the housing 8.
　また、反射傘１０の第２反射部１６と別体とすることにより、熱伝導部２７の加工が容易になる。その結果、生産性の向上や、低コスト化が可能となる。なお、第２反射部１６に蓄積される熱は、別途、熱伝導部を独立して設けて放熱してもよい。さらに、上記熱伝導部２７に熱伝導させて放熱するようにしてもよい。 In addition, by making the second reflecting portion 16 of the reflector 10 separate, the processing of the heat conducting portion 27 is facilitated. As a result, productivity can be improved and costs can be reduced. Note that the heat accumulated in the second reflecting portion 16 may be radiated by separately providing a heat conducting portion. Further, the heat conducting portion 27 may conduct heat to dissipate heat.
　また、上記実施の形態の光照射装置および光照射治療・予防装置１では、波長透過部４としてバンドパスフィルタを用いる例で説明したが、これに限られない。例えば、ショートパスフィルタ（長波長カットフィルタ）とロングパスフィルタ（短波長カットフィルタ）とを組み合わせて、入射された入射光の特定範囲の波長を選択して透過させる波長透過部４を用いてもよい。 Further, in the light irradiation device and the light irradiation treatment / prevention device 1 according to the above-described embodiment, the example in which the bandpass filter is used as the wavelength transmission unit 4 has been described, but the present invention is not limited thereto. For example, a wavelength transmission unit 4 that combines a short pass filter (long wavelength cut filter) and a long pass filter (short wavelength cut filter) to select and transmit a wavelength in a specific range of incident light may be used. .
　また、上記実施の形態の光照射装置および光照射治療・予防装置１では、光源として円筒形状の閃光放電管を用いる例で説明したが、これに限られない。例えば、光源は、軸方向に直列に配列された２以上の閃光放電管または直線状に配列させた複数のＬＥＤでもよい。また、透過部材の幅方向の延長に対応する光源を用いてもよい。これにより、用途に応じて、汎用性の高い光照射装置および光照射治療・予防装置を実現できる。 Further, in the light irradiation device and the light irradiation treatment / prevention device 1 according to the above-described embodiment, an example in which a cylindrical flash discharge tube is used as a light source has been described, but the present invention is not limited thereto. For example, the light source may be two or more flash discharge tubes arranged in series in the axial direction or a plurality of LEDs arranged linearly. Moreover, you may use the light source corresponding to the extension of the width direction of a transmissive member. Thereby, according to a use, a highly versatile light irradiation apparatus and light irradiation treatment / prevention apparatus can be realized.
　また、上記実施の形態の光照射装置および光照射治療・予防装置１では、透過部材５を構成する第１の透過面１３および第２の透過面１４が平面形状である例で説明したが、これに限られない。例えば、透過部材の第１透過面および第２透過面を、奥行き方向（光照射部の開口側から光源に向かう方向）に対して、例えば丸みを帯びた円弧状でもよく、さらに半円状でもよい。これにより、放射光をより均一化できるなどの効果が得られる。 In the light irradiation device and the light irradiation treatment / prevention device 1 according to the above-described embodiment, the first transmission surface 13 and the second transmission surface 14 constituting the transmission member 5 have been described as examples in a planar shape. It is not limited to this. For example, the first transmissive surface and the second transmissive surface of the transmissive member may have, for example, a rounded arc shape or a semicircular shape with respect to the depth direction (the direction from the opening side of the light irradiation unit toward the light source). Good. Thereby, the effect that the emitted light can be made more uniform can be obtained.
　また、上記実施の形態の光照射装置および光照射治療・予防装置１では、赤外線吸収層が着色アルマイト層である例で説明したが、これに限られない。例えば、赤外線吸収層は、熱吸収塗料を塗布して形成された層でもよく、熱線吸収ガラスを積層させた層で構成してもよい。 In the light irradiation device and the light irradiation treatment / prevention device 1 according to the above embodiment, the infrared absorption layer is a colored alumite layer. However, the present invention is not limited to this. For example, the infrared absorbing layer may be a layer formed by applying a heat absorbing paint, or may be a layer in which heat ray absorbing glass is laminated.
　また、上記実施の形態の光照射装置および光照射治療・予防装置１では、熱伝導部６が反射傘１０（反射部）と一体成形される例で説明したが、これに限られない。例えば、熱伝導部は、反射部に熱伝導可能に接続されておれば、どのような方法で接続されていてもよい。一例として、反射部と熱伝導部とを同一材質からなる部品で構成し、これらの部品を溶接や接着により一体に成形してもよい。 Further, in the light irradiation device and the light irradiation treatment / prevention device 1 according to the above-described embodiment, the example in which the heat conducting unit 6 is integrally formed with the reflector 10 (reflecting unit) has been described, but the present invention is not limited thereto. For example, as long as the heat conduction part is connected to the reflection part so as to be capable of heat conduction, the heat conduction part may be connected by any method. As an example, the reflection part and the heat conduction part may be formed of parts made of the same material, and these parts may be integrally formed by welding or bonding.
　以上で説明したように、本発明は、光源と、光源から放射される放射光を被照射体に向けて反射する反射部と、光源を格納する筐体と、を備える光照射装置である。そして、反射部に接続される放熱部を備え、筐体は、内側と外側とを貫通する放出部を有する、外側に突出して設けられる膨出部を備える。さらに、膨出部は、内側で放熱部を収容する構成を有していてもよい。 As described above, the present invention is a light irradiation apparatus including a light source, a reflection unit that reflects radiated light emitted from the light source toward an irradiated object, and a housing that stores the light source. And the heat dissipation part connected to a reflection part is provided, and a housing | casing is provided with the bulging part provided in the outer side which has the discharge | release part which penetrates an inner side and an outer side. Furthermore, the bulging part may have a configuration for accommodating the heat radiating part inside.
　この構成によれば、膨出部が筐体の外側に突出して設けられ、放熱部がその内側に収容することにより、外部と熱交換しやすくなる。そのため、光源の発光に伴って反射部に蓄積される熱は、膨出部の内側と外側とを貫通する放出部を介して放熱部から外部に放出されやすくなる。これにより、筐体内の熱を効率的に筐体の外部に放出することができる。その結果、使用時における、閃光放電管の冷却時間を短縮できる、高い効率の光照射装置を実現できる。 According to this configuration, the bulging portion is provided so as to protrude to the outside of the housing, and the heat radiating portion is housed inside thereof, thereby facilitating heat exchange with the outside. For this reason, the heat accumulated in the reflecting portion as the light source emits light is likely to be released from the heat radiating portion to the outside through the emitting portion penetrating the inside and outside of the bulging portion. Thereby, the heat in the housing can be efficiently released to the outside of the housing. As a result, it is possible to realize a highly efficient light irradiation device that can shorten the cooling time of the flash discharge tube during use.
　また、本発明の光照射装置は、反射部から放熱部に熱伝導可能な熱伝導部を、さらに備え、熱伝導部は、反射部から放出部まで連続して形成されていてもよい。 Moreover, the light irradiation device of the present invention may further include a heat conducting part capable of conducting heat from the reflecting part to the heat radiating part, and the heat conducting part may be continuously formed from the reflecting part to the emitting part.
　この構成によれば、光源の発光にともなって反射部に蓄積される熱は、熱伝導部に熱伝導されて放熱部に導かれ、放熱部から放熱される。これにより、筐体内に配置される光源の位置に関わらず、効率的に筐体の外部に熱を放出できる。 According to this configuration, the heat accumulated in the reflecting portion as the light source emits light is conducted to the heat conducting portion, is guided to the heat radiating portion, and is radiated from the heat radiating portion. Accordingly, heat can be efficiently released to the outside of the casing regardless of the position of the light source arranged in the casing.
　また、本発明の光照射装置は、反射部が、被照射体に向けて放射光を反射する反射面を有し、反射面は、少なくとも可視光を反射して赤外線を透過する光学多層膜と、赤外線を吸収する赤外線吸収層とから構成されていてもよい。 Further, in the light irradiation device of the present invention, the reflection portion has a reflection surface that reflects the emitted light toward the irradiated object, and the reflection surface includes an optical multilayer film that reflects at least visible light and transmits infrared rays. And an infrared absorbing layer that absorbs infrared rays.
　この構成によれば、光源から放射される放射光は、反射部の光学多層膜で可視光を被照射体に反射し、赤外線を赤外線吸収層に透過する。そして、光学多層膜を透過した赤外線は、赤外線吸収層で吸収される。これにより、光源の発光により反射部で発生する熱を、高い効率で反射部から熱伝導部に熱伝導できる。その結果、反射部の熱を、放熱部を介して、効率的に筐体の外部に放出させることができる。 According to this configuration, the radiated light emitted from the light source reflects visible light to the irradiated object by the optical multilayer film of the reflecting portion, and transmits infrared light to the infrared absorbing layer. And the infrared rays which permeate | transmitted the optical multilayer film are absorbed in an infrared rays absorption layer. Thereby, the heat which generate | occur | produces in a reflection part by light emission of a light source can be thermally conducted from a reflection part to a heat conduction part with high efficiency. As a result, the heat of the reflection part can be efficiently released to the outside of the housing via the heat dissipation part.
　また、本発明の光照射装置は、放射光を透過する透過部材を備え、光源は、透過部材の透過面に接する直線より被照射体側に配置される。反射部は、直線より透過部材の被照射体側と反対側に向かう放射光を透過部材に反射する第１反射部と、直線より被照射体側に向かう放射光を第１反射部に反射する第２反射部と、を備える。そして、放熱部は、反射部の第１反射部と一体的に接続されていてもよい。 Further, the light irradiation device of the present invention includes a transmission member that transmits radiated light, and the light source is disposed on the irradiated object side with respect to a straight line that contacts the transmission surface of the transmission member. The reflecting part reflects the radiated light from the straight line toward the opposite side of the transmissive member to the irradiated body side, and reflects the radiated light from the straight line toward the irradiated body side to the first reflective part. And a reflection part. And the thermal radiation part may be integrally connected with the 1st reflection part of the reflection part.
　この構成によれば、第１反射部は、第２反射部と比較して、第２反射部から誘導される放射光と、光源から直接放射される放射光との、両方の放射光を反射する。そのため、放射光の熱的な影響をより多く受けて、第１反射部は高温になりやすい。このとき、熱伝導部を第１反射部と一体に成形することにより、第２反射部からよりも第１反射部から熱を熱伝導しやすくなる。これにより、高温になりやすい第１反射部の熱を、第２反射部の熱よりも、効率的に筐体の外部に放出させることができる。その結果、筐体内の熱を効率的に筐体の外部に放出して、使用時の光源の冷却時間を短縮できる。 According to this configuration, the first reflecting unit reflects both radiated light, which is emitted from the second reflecting unit and radiated directly from the light source, as compared to the second reflecting unit. To do. For this reason, the first reflecting portion is likely to be hot due to more thermal influence of the emitted light. At this time, by forming the heat conducting part integrally with the first reflecting part, it becomes easier to conduct heat from the first reflecting part than from the second reflecting part. Thereby, the heat | fever of the 1st reflection part which tends to become high temperature can be efficiently discharged | emitted to the exterior of a housing | casing rather than the heat of a 2nd reflection part. As a result, the heat in the casing can be efficiently released to the outside of the casing, and the cooling time of the light source during use can be shortened.
　また、本発明は、上記に記載の光照射装置から照射される光を生体の特定部位に照射することにより、治療または予防する光照射治療・予防装置である。そして、光源から放射される光の光路上に配置され、光源から放射される放射光のうち、波長が５６６．５ｎｍ以上７８０ｎｍ以下の範囲内の放射光を透過させる波長透過部を備える。さらに、波長透過部を透過させた透過光を生体の特定部位に照射可能な構成を有していてもよい。 Further, the present invention is a light irradiation treatment / prevention device that treats or prevents light by irradiating a specific part of a living body with light irradiated from the light irradiation device described above.
