Description

  The present invention is used for otolaryngology, dentistry, etc., when a doctor examines or treats and irradiates light by reflecting a deeply affected area in a patient sitting on an examination chair with a reflecting mirror. The present invention relates to a lighting device.

  In otolaryngology, when the affected part such as the back of the ear canal, the back of the nostril, the back of the throat, etc. is irradiated with light, and the back tooth is irradiated with dentist for examination and treatment, it is shown in FIG. As described above, the reflecting mirror 16 is attached to the forehead 15 wound around the back of the head from the forehead, and the affected part is irradiated by reflecting the light beam from the light source 17. The light source 17 is configured so that a plurality of arms are connected by joints and can move in all directions. The patient 10 sits on the examination chair 12, has his back closely attached to the backrest 18, and supports the head 14. When closely attached to the head 13, the doctor 11 changes the position and orientation of the light source 17 so as to pass the light most depending on the position of the affected part, and peeks through the viewing hole 19 of the reflecting mirror 16 for treatment and diagnosis (Patent Document). 1).

  Further, there is also known one in which a light bulb as a light source is incorporated at the focal position of a reflecting mirror in the forehead portion of the frame (Patent Document 2).

JP 2001-327559 A Utility Model Registration No. 3031574

  According to the invention described in Patent Document 1, the doctor 11 adjusts the light source 17 by changing the position and orientation of the light source 17 so that the light beam passes most depending on the position of the affected part while looking into the affected part from the viewing hole 19. Since 17 is behind the patient 10, there is a risk that the head 14 may hit the light source 17 when the patient 10 stands up, and the doctor 11 can extend and contract the arm supporting the light source 17 with one hand or change the angle. Since the light beam is adjusted by using the light source 17, one hand cannot be used, which has hindered the treatment and examination performed with both hands, and since the light source 17 mainly uses an incandescent bulb, both the patient 10 and the doctor 11 use the light source 17. It was hot due to the heat generated, the support base for supporting the light source 17, a plurality of arms, the joint part for connecting the arms to each other became large and expensive. There was a problem.

  Since the invention described in Patent Document 2 has a small light bulb built in the focal position of the reflector on the forehead, the amount of light tends to be insufficient, and when a dry battery is used as a power source, If it is stored so as to be placed on the part, it will be obstructed by the doctor 11 and work will be interrupted, and the battery will run out. When power is supplied from a large power source, there is no shortage of battery capacity or battery exhaustion, but there is a problem that the cord connecting the power source and the light bulb interferes with the work of the doctor 11.
