To provide a device which can observe a tooth portion and a mouth of a patient by natural light when radiating a radiation beam of a dental lighting device to the tooth portion and the mouth of the patient at a dental care by dentist or the like.SOLUTION: A dental lighting device 10 is constituted of an outer frame 10A and a display part 10B, and the display part 10B is established by an alignment group of LEDs (light emitting diodes). The lighting device is constituted of four stages and eight rows, and a combination of white light emitting LEDs 10a and red light emitting LEDs 10b. Then, in a first stage, two pieces of the white light emitting LEDs 10a, one piece of the red light emitting LED 10b adjacent thereto, two pieces of the white light emitting LEDs 10a adjacent thereto, one piece of the red light emitting LED 10b adjacent thereto, and two pieces of the white light emitting LEDs 10a adjacent thereto are arranged continuously from a left side with proper intervals. Also in a second stage to a fourth stage, the white light emitting LEDs 10a and the red light emitting LEDs 10b are properly mixed and aligned in a form not similar to that of the first stage.SELECTED DRAWING: Figure 2【課題】歯科医師等が歯科治療で患者の歯部分や口元に歯科用照明装置の放射光を照射した場合、自然光で観察することができる装置を提供する。【解決手段】歯科用照明装置１０は外枠１０Ａと表示部１０Ｂとで構成され、該表示部１０ＢはＬＥＤ（発光ダイオード）の配列群で成立する。４段かつ８列であって、白色発光ＬＥＤ１０ａと、赤色発光ＬＥＤ１０ｂの組合せで構成されている。そして１段目に於いて左側から連続して適宜間隔を置いて２個の白色発光ＬＥＤ１０ａを、それに隣接して１個の赤色発光ＬＥＤ１０ｂ、それに隣接して２個の白色発光ＬＥＤ１０ａで、更に、それに隣接して１個の赤色発光ＬＥＤ１０ｂを次でそれに隣接して２個の白色発光ＬＥＤ１０ａを配置して構成される。２段目から４段目に於いても１段目と同様な形態で同一配列ではないが適宜に白色発光ＬＥＤ１０ａ及び赤色発光ＬＥＤ１０ｂを混在させて配列構成する。【選択図】図２
