  The present invention relates to a small headlight-type lighting device that is used by being mounted on a spectacle frame or the like.

As an illuminating device that has been used for diagnosis aids such as otolaryngology and dentistry for a long time, there is a forehead mirror that can be attached to the head because of the need to ensure the freedom of both hands of the operator. The forehead mirror is composed of a concave mirror of a condensing unit having an observation opening at the center, and is disposed in front of the face.

The frame mirror composed of concave mirrors has a simple structure, but the concave mirrors occupy a relatively large area, which hinders the field of view of the actual person and has a drawback if the light quantity of the illumination unit cannot be adjusted.

In recent years, as small LEDs (light emitting diodes) having high luminous efficiency are put into practical use, for example, a frame mirror in which a small LED is incorporated as a lighting device in a portion corresponding to a concave mirror as disclosed in Patent Document 1 is disclosed. Yes.

In addition, spectacle-type illumination devices in which small illuminating means are mounted on spectacle frames as disclosed in Patent Documents 2 and 3 are also disclosed.

In particular, the use of LEDs as the illumination light source makes it easy to adjust the amount of light of the illumination device and enables reduction in size and weight. Recently, illumination devices such as frame mirrors incorporating LEDs have been widely used.

  When an illuminating device using LEDs is mounted on the entire surface of the spectacle frame, the illuminating device is positioned in front of the spectacle frame, so that a heavy load is applied to the frame and the mounting feeling is deteriorated. In order to solve this, it is desirable to reduce the weight load applied to the spectacle frame.

Means for solving the problems are as follows:
An illumination device including an illumination unit composed of an LED having an attachment member attached to the front part of the spectacle frame and an optical system, and having a weight reduction holding member from the tip of the illumination unit toward the nose. A lighting device characterized by
Furthermore, the weight reduction holding member is characterized in that it is constituted by a plurality of holding members connected so as to be relatively bendable from the tip portion toward the nose.

  Since the lighting device according to the present invention has a simple structure and can reduce the weight load applied to the frame of the glasses, it does not require a glasses frame having a special structure and can be applied to various glasses.

It is explanatory drawing which shows the use condition which mounted | wore the front surface of the spectacles frame with the illuminating device by this invention. It is explanatory drawing which shows the state which integrated the illumination means using LED of the illuminating device by this invention, and the battery accommodating part which drives LED.

  FIG. 1 is an explanatory diagram when the lighting device according to the present invention is mounted on the front surface of a spectacle frame, and is characterized in that a weight reduction holding member is provided from the tip of the lighting device toward the nose.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic explanatory view showing an illuminating device according to the present invention, and a part of the drawing is shown in cross section for easy understanding. In the figure, reference numeral 10 denotes an illuminating means. The illuminating optical system is composed of lenses 11 and 12 and includes an LED 14 as a light source and is incorporated in a housing 13.

In FIG. 1, 15 is a mounting board for the LED 14, 16 is a volume with a switch for adjusting the light quantity of the LED, and 17 is a circuit board for lighting the LED. Although not shown, a battery storage unit such as a battery for driving the LED is disposed at a location away from the illumination device and is connected to the illumination means 10 by a cable or the like.

The illuminating means 10 is attached to a holding member 18, and the holding member is attached to the attachment member 19 via a ball junction composed of a ball bearing 20 and a ball 21, and the attachment member 19 is attached to a spectacle frame 22. It sticks to. Thus, when the illumination means 10 is attached to the attachment member 19 via the ball junction, the position of the illumination range of the illumination means can be adjusted.

The clamping grip 22 attached to the spectacle frame is composed of clamping plates 24 a and 24 b and a spring member 25.

FIG. 2 is a front view of the illuminating device as viewed from the front, and is attached to the spectacle frame 35 indicated by the dotted line shown in FIG. The reference numerals shown in FIG. 2 are the same as those used in FIG.

FIG. 3 shows a state in which the illuminating device is actually attached to the glasses. As shown in FIG. 3, the illuminating device is attached to the front surface of the spectacle frame 35 in such a manner that the front end of the spectacle frame holding grip 22 shown in FIG.

  When the illuminating device is attached to the spectacle frame 35, the illuminating device can be easily attached and detached, but the weight of the illuminating device is applied to the front surface of the spectacles, so the feeling of wearing becomes worse and the burden on the operator is great.

  The present invention is characterized by remarkably reducing the heavy wearing feeling given to the operator by providing a weight reduction holding member 30 that comes into contact with the front surface of the wearer's nose from the front of the lighting device attached to the glasses. .

  As shown in FIG. 3, when the weight reduction holding member 30 is provided on the front surface of the wearer's nose from the front of the lighting device to be worn on the glasses, the weight is the shape of the glasses or the shape of the face of the person wearing the glasses. The nose pad member 35 provided at the tip of the reduction assisting member 30 does not necessarily contact with a part of the nose in an optimal state.

  In order to solve the above problem, as shown in FIGS. 1, 2, and 3, the weight reduction holding member 30 according to the present invention is composed of two holding members 31, 32, and the holding members 31, 32 are pins. It is connected at 34 and can be bent relatively. The holding member 31 is connected to the holding member 19 by a pin 33 and can be bent. The weight reducing member 30 may be composed of two or more holding members.

  Even if the holding member is constituted by a single member, a sufficient effect can be simply expected, so that the holding member may be a single member.

  In the weight reducing holding member 30 having the above-described configuration, the nose pad member 35a disposed at the tip of the holding member 32 can be selected in an optimum position, so that even when it is worn on a wide variety of glasses, the weight reducing wearing member 30a can be selected. A feeling effect can be expected.

  In the illuminating apparatus described so far, in order to reduce the weight load applied to the spectacle frame, the battery housing portion is separated from the lighting portion means. However, as shown in FIG. 4, the battery housing portion 25 is shown in FIG. A part of the holding member 18 can be attached to the extended holding member 18a, and the battery housing part 25 can be integrated with the lighting means 10.
