図１は、本発明による歯科用無影灯の一実施例を説明するための図で、図中、１０は無影灯で、該無影灯１０は、図４に示した従来の無影灯と同じで、ハロゲンランプ等の光源１１、該光源１１からの光が直接患者に照射されるのを防止する遮光板１２、光源１１からの光を乱反射（散光）して患者の方に向ける湾曲状の反射ミラー１３、透明体のカバー１４等からなり、周知のように、光源１１からの光を反射ミラー１３によって散光させて前方に照射するようにしたものである。２０は該無影灯１０に一体的に設けられ、歯科診療時、患者の顔を撮影するカメラ、３０は該カメラ２０によって撮影された患者の顔を表示するモニタで、該モニタ３０は、必ずしも必要はなく、例えば、ワークテーブル等に設けられているモニタを用いることもできる。   FIG. 1 is a view for explaining an embodiment of a dental surgical light according to the present invention. In the figure, 10 is a surgical light, and the surgical light 10 is the conventional surgical light shown in FIG. Same as a lamp, a light source 11 such as a halogen lamp, a light shielding plate 12 that prevents light from the light source 11 from being directly irradiated to the patient, and light from the light source 11 is diffusely reflected (diffused) and directed toward the patient. As is well known, the reflection mirror 13 is made up of a curved reflection mirror 13, a transparent cover 14, and the like. The light from the light source 11 is scattered by the reflection mirror 13 and irradiated forward. Reference numeral 20 is provided integrally with the surgical light 10, and a camera for photographing a patient's face at the time of dental treatment, 30 is a monitor for displaying the patient's face photographed by the camera 20, and the monitor 30 is not necessarily For example, a monitor provided on a work table or the like can be used.

本発明においては、歯科診療時において、術者が無影灯を患者の顔に向け、カメラ２０をオン状態にする（或いは、無影灯が患者の顔と接近したことを検知して該カメラを自動的にオン状態とする）と、カメラ２０は患者の顔を撮影し、モニタ３０に表示する。カメラ２０は患者の口の開閉を認識することができ、患者が口を開いた時は、無影灯１０を点灯し、口を閉じた時は無影灯１０からの照射光を弱くし或いは無影灯１０を消灯する。これによって、術者が患者の口腔内を診療していない時は、患者の目に入る無影灯１０からの光が軽減され、患者の不快感が低減される。   In the present invention, at the time of dental treatment, the surgeon directs the surgical light toward the patient's face and turns on the camera 20 (or detects that the surgical light has approached the patient's face and detects the camera). Is automatically turned on), the camera 20 captures the patient's face and displays it on the monitor 30. The camera 20 can recognize the opening and closing of the patient's mouth. When the patient opens the mouth, the operating light 10 is turned on, and when the mouth is closed, the irradiation light from the operating light 10 is weakened. The surgical light 10 is turned off. Thus, when the surgeon is not treating the patient's oral cavity, the light from the surgical light 10 entering the patient's eyes is reduced, and the patient's discomfort is reduced.

図２は、本発明による無影灯の他の実施例を説明するための図で、図中、１５は光源収納部で、該光源収納部１５には複数の光源１６が略同一の平面内に設けられており、或いは、多数の有機ＥＬからなる光源が平面状に設けられており、これら光源からの光が光源収納部１５の前面に設けられた透光性の光拡散板１７を通して前方に無影光として照射されるようになっている。このような無影灯に対しても、前述のように、カメラ２０によって患者の口の開閉を認識し、患者の口の開閉に応じて光源を点滅することにより、換言すれば、患者が口を閉じている時は光源を消灯して、患者の目に入る光を軽減することができる。   FIG. 2 is a view for explaining another embodiment of the surgical lamp according to the present invention. In the figure, 15 is a light source storage portion, and a plurality of light sources 16 are in the same plane in the light source storage portion 15. Or a light source made of a large number of organic ELs is provided in a flat shape, and light from these light sources passes through a translucent light diffusion plate 17 provided on the front surface of the light source storage unit 15. Is irradiated as shadowless light. Even for such a surgical light, as described above, the camera 20 recognizes the opening / closing of the patient's mouth and blinks the light source in accordance with the opening / closing of the patient's mouth. When is closed, the light source can be turned off to reduce light entering the patient's eyes.

図３は、本発明の他の実施例を説明するための要部分解斜視図で、本実施例は、図２に示した無影灯において、前記光拡散板１７の表面に調光フィルム１８を設け、この調光フィルム１８の光透過率を患者の口の開閉に応じて変化させるようにしたものである。調光フィルム１８は、該調光フィルム１８に印加する電圧をオン・オフすることにより、該調光フィルム１８を透光性にしたり遮光性にしたりすることが可能であり、前述のように、カメラ２０によって患者の口の開閉を認識した時に、光源を点滅させる代わりに、該調光フィルム１８の透光率を変えることにより、患者が口を閉じている時には、無影灯からの光が患者に届かないようにすることができる。   FIG. 3 is an exploded perspective view of an essential part for explaining another embodiment of the present invention. This embodiment is a shadowless film 18 on the surface of the light diffusing plate 17 in the shadowless lamp shown in FIG. The light transmittance of the light control film 18 is changed according to the opening / closing of the patient's mouth. The light control film 18 can make the light control film 18 translucent or light-shielding by turning on and off the voltage applied to the light control film 18, as described above. When the opening and closing of the patient's mouth is recognized by the camera 20, instead of blinking the light source, the light from the surgical light is changed when the patient closes the mouth by changing the light transmittance of the light control film 18. It can be prevented from reaching the patient.

更には、前記調光フィルム１８を、図３に破線にて示すように、横方向にストライプ（短冊）状に延長させ、これらストライプを縦方向に透光率を変えるようにしておくことも可能で、例えば、図示のように、横方向に延長するストライプ１８1、１８2、１８6、１８7の透光率を低く（遮光）し、１８3〜１８5の透光率を高くする（どのストライプの透光率を変化させるかは、カメラ２０と該カメラ２０に付随する顔認識のためのソフトウェア解析装置により患者の顔等の認識を自動的に行う）ことによって、例えば、患者の顔の大きさに合せて透光（又は、遮光）パターンにすることが可能であり、患者の口の位置や大きさに合せて、透光率の高いストライプの位置や数（パターン）を変える。 Furthermore, the light control film 18 can be extended in the form of stripes (stripes) in the horizontal direction as indicated by broken lines in FIG. 3, and the light transmittance can be changed in the vertical direction. Thus, for example, as shown in the figure, the transmissivity of the stripes 18 1 , 18 2 , 18 6 , and 18 7 extending in the lateral direction is lowered (shielded), and the transmissivities of 18 3 to 18 5 are increased ( The light transmittance of which stripe is changed is determined by automatically recognizing the patient's face and the like by the camera 20 and a software analysis device for face recognition attached to the camera 20). It is possible to make a light-transmitting (or light-shielding) pattern according to the size of the pattern, and the position and number (pattern) of stripes with high light transmittance are changed according to the position and size of the patient's mouth.

上述のように、本発明によると、患者の口の開閉に応じて、無影灯から照射される光をオン・オフ（透光・遮光）させるようにしたので、患者が口を開いていない時（口腔内を診療していない時）は、無影灯からの光が患者の目に入ることがなく、患者は不快感を受けることなく診療を受けることができる。   As described above, according to the present invention, according to the opening / closing of the patient's mouth, the light emitted from the surgical light is turned on / off (translucent / shielded), so the patient does not open the mouth. At times (when not in the mouth), the light from the surgical light does not enter the patient's eyes, and the patient can be treated without discomfort.

また、患者の顔の大きさ等に応じて、調光フィルムの透光（遮光）パターンを変えることにより、無影灯から照射される光のパターンを変えることができるので、患者の顔の大きさ（子供、大人）に関らず、患者の口部のみを照明し、目部には光を照射しないようにしたので、患者に不快感を与えることなく、歯科治療を行うことができる。   In addition, the pattern of light emitted from the surgical light can be changed by changing the translucent (light-shielding) pattern of the light control film according to the size of the patient's face, etc. Regardless of the size (children and adults), only the patient's mouth is illuminated and the eyes are not irradiated with light, so that dental treatment can be performed without causing discomfort to the patient.
