Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention is used for dental treatment, etc.
The present invention relates to an operating light for illuminating an affected part of a patient.

[0002]

2. Description of the Related Art Conventionally, in dental treatments and the like, surgical lights have been widely used as illuminators for illuminating an affected part of a patient.
The operating light is provided with a light-shielding plate in front of the lamp to prevent direct illumination with the light of the lamp, and a reflecting mirror (scattering plate) is installed behind the lamp to make the number of light sources virtually infinite. It is largely (in other words, a surface light source) that does not allow the shadow of the object to be irradiated, and is suitable for irradiating the affected part in treatments such as dentistry and otolaryngology. The lamp, the light shielding plate, and the reflection mirror are attached to the support directly or via an appropriate support, and the support is configured to be rotatable so that the illumination position can be freely adjusted. .

The mirror reflects the light emitted backward from the lamp to the front as a surface light source, and is usually formed in an arc shape. Further, the light-shielding plate is for preventing light from the lamp from directly going to the object to be illuminated, whereby the surface light source is kept uniform. ,
There has also been proposed a device in which a light beam emitted from the lamp forward is reflected by a reflection plate to a reflection mirror, and is reflected again by the reflection mirror to be used for illumination.

FIG. 2 is a view for explaining an example of a conventional surgical light. In FIG. 2, reference numeral 1 denotes a grip provided on both sides of a reflection mirror, 2 denotes a reflection mirror, 3 denotes a lamp, and 4 denotes a lamp. 5 is a lamp mounting plate, 6 is a lamp support plate, 7 is a lamp support plate mounting member, and 8 is a mounting member.
The operating light 8 is rotatably fixed to the supporting arm member via the joint 9.

[0005]

FIG. 3 is a view when the patient's mouth is illuminated by the surgical light as described above, and an area A indicated by a diagonal line to the left is illuminated by the surgical light. Although it is an area, in reality, light leaking from the head 3a of the lamp 3 appears in a part of an area B indicated by oblique lines falling to the right, which has a problem that the light enters a patient's eyes and is dazzling.

[0006]

According to the present invention, in order to solve the above-mentioned problems, a reflection mirror is provided at the rear of the lamp, and the light from the lamp is reflected by the reflection mirror so as to be in front of the lamp. A light-shielding plate or a reflector in front of the lamp, and the light-shielding plate or the reflector shields or reflects light emitted from the lamp to the front of the lamp. In the operating light, the head of the lamp is covered with a light-blocking member, or the light-shielding plate or the reflection plate is folded back to cover the head of the lamp. Hereinafter, an embodiment of the present invention will be described.

FIG. 1 is a view for explaining an embodiment of an operating light according to the present invention. In FIG. 1, parts which operate in the same manner as the prior art shown in FIG. The same reference numbers are assigned. In the present invention, the cover 3 of the light shielding member is provided on the head 3a of the lamp 3.
This prevents light leaking from the head of the lamp 3 from entering the patient's eyes. Although the figure shows an example in which the head itself of the lamp 3 is shielded from light, in addition to this, for example,
The light shielding plate may be configured such that the reflection plate 4 is folded back as shown by a chain line in the figure so that light emitted from the head of the lamp 3 does not reach the reflection mirror 2.

[0008]

As is apparent from the above description, according to the present invention, the light emitted from the head of the operating lamp does not enter the patient's eyes, so that the patient is comfortable and dazzling. Can receive.
