Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an improvement in a lighting device that irradiates a patient's mouth during diagnosis and treatment.

[0002]

[Prior art]

 As shown in FIG. 3, a bulb (halogen lamp) 21 is fixed to a portion corresponding to the forehead of a band 20 wound around the head, and the bulb 21 illuminates an affected part in the oral cavity at the time of diagnosis or treatment. There is something.

[0005] However, since the bulb 21 is heated and the wearing doctor may be burned, it cannot be used for a long time. Another drawback is that the heat of the light bulb is transmitted to the patient, causing fear and hindering treatment. Further, there is a disadvantage that power consumption is large.

[0004] As a remedy, it has been considered to mount a light bulb at a position distant from the center of the forehead.

[0005]

[Problems to be solved by the invention]

 In view of the above, an object of the present invention is to provide a lighting device arranged in the center of the forehead and to provide a device that is safe for a doctor or a patient even after long use.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the invention of claim 1 is characterized in that a white light diode is used as the light source in an oral lighting device that irradiates the inside of the oral cavity with a light source fixed to the head. The lighting device for an oral cavity according to claim 2, wherein the light emitting unit accommodating the white diode is connected to a clip unit including a holding unit for holding a frame of eyeglasses and an angle adjusting unit for adjusting an angle of the light emitting unit. Become. According to a third aspect of the present invention, in the oral lighting device, the light emitting unit according to the second aspect is formed by an outer cylinder and an inner cylinder each having a lens attached to a tip, and a white diode is housed in the inner cylinder. It is characterized in that the outer circumference of the inner cylinder is covered with an outer cylinder, and the outer cylinder is made movable relative to the inner cylinder, so that the distance between the lenses attached to the respective tips is varied. Note that the term “movable relative to the inner cylinder relative to the inner cylinder” includes a case where the inner cylinder is fixed and the outer cylinder is slidable, and a case where the outer cylinder is fixed and the shooting cylinder is slidable. .

[0007]

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view of an oral lighting device. Reference numeral 1 denotes a light emitting unit, which is connected to a power supply via a power cord 2. Reference numeral 4 denotes a switch arranged in the middle of the power cord 2. The power supply may be an AC power supply as shown in FIG. 1 and may be connected to the light emitting unit 1 via the converter 5 or a DC power supply such as the dry cell 3.

The light emitting section 1 includes an outer cylinder 6 and an inner cylinder 7, and accommodates a white diode 8 in the inner cylinder 7 and accommodates the inner cylinder 7 in the outer cylinder 6. As shown in FIG. 2, for example, three white diodes 8 are bundled to secure the light quantity. Reference numeral 9 denotes an outer cylinder holding member integrated with the inner cylinder 7, which holds the outer cylinder 6 slidably to the left and right in the drawing. Also, a lens 10 is attached to the tip of the inner cylinder 7 and a lens 11 is attached to the tip of the outer cylinder 6, and the light emitted from the white diode 8 is appropriately diffused by changing the distance between the lenses 10, 11. I squeeze.

Reference numeral 12 denotes a clip portion, which comprises a holding portion 13 and an angle adjusting portion 14. The holding portion 13 has a shape of a clothespin as shown in FIG. 2, and holds the frame 16 of the glasses by the force of the spring 15. The angle adjusting part 14 is connected to the holding part 13 and includes a U-shaped part 17 and a shaft 19 inserted into a hole 18 formed in the side wall of the U-shaped part 17. It can be freely supported.

In the lighting device for an oral cavity described above, the light emitting unit 1 is mounted by holding the frame 16 of the glasses with the holding unit 13. Next, the light emitting unit 1 is adjusted to an arbitrary angle by the angle adjusting unit 14 according to the position of the affected part, and the distance between the lenses 10 and 11 is changed to adjust the aperture according to the purpose of irradiation. Switch 4 is turned on. For example, diffuse light is selected to irradiate the oral cavity widely, and aperture light is selected to irradiate the affected part.

It is also possible to use a small battery and house it in the cylindrical light emitting unit 1 to make it cordless. In addition, when diagnosing or treating the oral cavity, doctors usually wear eyeglasses to protect the eyes from blood splashing from the affected area, etc. There is an advantage that no special fixing device such as a band is required.

Further, in the above-described embodiment, the outer cylinder is slidable. Alternatively, the outer cylinder may be fixed and the inner cylinder may be slidable.

[0013]

[Effect of the invention]

 In short, since the present invention uses a white diode as a light source of the oral lighting device, there is no burn due to heat generation of the light source. In addition, the patient can be diagnosed and treated smoothly without being scared by the heat generated from the light source. It is economical with low power consumption. In addition, since the light emitting section containing the white diode is connected to the clip section, the clip section allows the light emitting section to be attached to and detached from eyeglasses of various shapes used by a doctor. Also, by making the outer cylinder relatively movable with respect to the inner cylinder and changing the distance between the lenses attached to the respective tips, the aperture is adjusted, for example, to irradiate aperture light and diffused light. The light can be selected according to.
