PROBLEM TO BE SOLVED: To mount a photo/electric converter on a light shielding plate of a dental shadeless lamp, to allow this lamp to generate electricity and to effectively utilize this electric energy. SOLUTION: The shadeless lamp 10 has a reflection mirror 12 behind a lamp 11 to reflect the light from the lamp 11 by this reflection mirror 12 and to project this light to the front of the lamp and has the light shielding plate 13 in front of the lamp 11 to shield the light released to the front of the lamp from the lamp 11 by this light shielding plate 13. The shadeless lamp has the photo/electric converter 20 on the front surface of the light shielding plate 13 on the side facing the lamp 11. The light radiated from the lamp 11 is converted to the electricity by the photo/electric converter 20 and this electricity is used as part of a light source for odontotherapeutic instruments. |
