Abstract

(57) [Summary] [Purpose] It works in the same way as a regular surgical light when illuminating the oral cavity, and it can illuminate a wider area during manual operation.
Make manual work easier. [Structure] Light emitted from a light source 2 is reflected by a reflecting plate 1 and used. When the light source 2 is at the solid line position shown in the figure, it is at the focal point of the reflector plate 1, and operates in the same manner as a normal surgical light, illuminating the inside of the oral cavity. When performing manual work such as cutting and adjusting dentures, move the entire surgical light and
For example, the motor 3 is driven to move the light source 2 to the position indicated by the chain line in the drawing and to shift it from the focal position of the reflector 1. Then, the light reflected from the reflector 1 becomes spread out, so the illuminated area becomes wider and manual work becomes easier.

【Technical field】

The present invention relates to a dental surgical light.

0002

[Prior art]

In dental treatment, surgical lights are used to illuminate the inside of the oral cavity. This shadowless As is well known, a light consists of a reflector with a parabolic reflective surface, and the focal position and arrangement of this reflector. The light emitted from the light source is reflected by the reflecting plate to produce approximately It is made into parallel light beams and used for illuminating the oral cavity. Therefore, in dental treatment For example, there is manual work such as cutting and adjusting dentures, etc. In such cases, surgical lights are also used. People are working by using the light from the room to brighten their surroundings. But long However, dental operating lights usually have a narrow illumination range (area), and as mentioned above, manual operation is required. When doing this, if you cannot immediately see where the light is, move your hand to a bright place. I had to search for it, which was very troublesome.

【the purpose】

This invention was made in view of the above-mentioned circumstances, and is particularly applicable to dental surgical lights. Then, move the light source so that it is away from the focal point of the reflector, and The purpose was to illuminate a wider area when shifted. It is something that

【composition】

In order to achieve the above object, the present invention provides a reflecting plate having a parabolic reflecting surface and a reflecting plate having a parabolic reflecting surface. a light source disposed at the focal point of the plate, and the light emitted from the light source is reflected by the reflecting plate. In a dental surgical light that illuminates by reflection at a means for moving the light source away from the focal position and a position away from the focal position; It is characterized by being able to be selectively fixed in two positions. The following is the explanation of this invention. This will be explained based on an example.

[0005] FIG. 1 is a configuration diagram for explaining an embodiment of a dental surgical light according to the present invention. , 1 is a reflecting plate having a parabolic reflecting surface, 2 is a light source disposed at the focal point of the reflecting plate 1, As is well known, the light emitted from the light source 2 is reflected by the reflection plate 1 and is approximately parallel to the light emitted from the light source 2. It is used as a ray of light. Therefore, when the above-mentioned surgical light is used for intraoral illumination, There is no problem with this, but as mentioned above, when adjusting dentures etc. manually, If you try to illuminate your area with the above-mentioned surgical light, the illumination range is narrow, so the illumination It was troublesome to search for the range.

[0006] The present invention was made in order to solve the problems of the conventional technology as described above. As shown by the chain line in the figure, the position of the light source 2 is shifted from the focal position of the reflector 1. It was made by sea urchin. In this way, the position of the light source 2 is shifted from the focal position of the reflector 1. Then, the light reflected by the reflector 1 will not be parallel rays, but will be angular in the direction in which it spreads. It will be reflected with a higher degree of intensity, so a wider area will be illuminated. 3 is By pressing a switch (not shown) on the motor for moving the above light source, , the light source 2 moves to the solid line position or the dashed line position shown in the figure. Specifically, it illuminates the inside of the oral cavity. When performing manual work, the light source 2 is at the solid line position shown at the focal point of the reflector 1. At this time, the surgical light is moved and the light source 2 is placed at the position indicated by the chain line. by this, When illuminating the inside of the oral cavity, it works in exactly the same way as a well-known surgical light, and when performing manual work, Illuminates a wider area to make manual work easier.

[0007] Note that the above describes an example in which a motor is used as a means to move the light source 1. As explained above, it is not limited to motors, but also plungers, hydraulic cylinders, spring means, manual Any desired means of transportation may be used, such as transportation by. The light source is fixed at the two positions above. In addition, although the example in which only the light source 2 is moved is explained in the figure, It is easily possible to move and fix the support member 4 that supports the light source 2. I can understand.

[0008]

【effect】 As is clear from the above explanation, according to the present invention, the light source in the dental operating light can be shifted from the focus position of the reflector, and when shifted, illuminates a wider area This allows you to illuminate a wider area when trying to illuminate areas other than the inside of the oral cavity. For example, when performing manual work using the light of a surgical light, It becomes easier to remove.
