Description

  The present invention relates to a hair growth-regulating light irradiation device that irradiates a light irradiation target with light for adjusting hair growth.

  2. Description of the Related Art Conventionally, a hair growth-regulating light irradiation device that applies light to the skin that is a light irradiation target, suppresses or promotes the growth of body hair, and performs hair removal or hair growth is known (for example, see Patent Document 1).

  In this type of hair growth adjusting light irradiation device, it is required to irradiate light in the vertical direction with respect to the hairy skin. In the hair growth adjusting light irradiation device disclosed in Patent Document 1, A plurality of contact sensors are arranged at positions surrounding the light irradiation port at the tip of the device, and light irradiation is started when it is determined that each contact sensor is in a vertical posture when contact with the skin is detected.

However, in the conventional hair growth regulating light irradiation device, since the head portion where the contact sensor is disposed surrounds the entire circumference of the light irradiation port, it is difficult to perform treatment such as irradiating light at an accurate irradiation position. . In other words, it is possible to grasp the approximate position by illuminating the irradiation position with the light from the light irradiation port at a position away from the skin, but since it is not known accurately, light is applied to any part of the skin during treatment. It was not possible to confirm whether it was irradiated, and light could not be reliably applied to a desired part of the skin. For this reason, excessive irradiation in which light is continuously irradiated over and over the same portion may occur. Although the surface after irradiation can be grasped by applying a photosensitive agent or the like, the next irradiation operation must be carefully performed so as not to overlap with the irradiated surface. In addition, in order to prevent omission of irradiation, it is necessary to irradiate with a little overlap, and the overlapped portion is excessively irradiated, resulting in a problem that the safety and work efficiency are deteriorated.

  The present invention has been invented in view of the above-mentioned conventional problems, and is provided with a light-shielding plate for preventing light leakage that surrounds the light irradiation port. An object of the present invention is to provide a hair growth regulating light irradiation device that can be easily positioned at the irradiation position of an object, thereby preventing excessive irradiation of light and omission of light, and improving the safety and work efficiency of light irradiation.

  In order to solve the above-described problems, the present invention is a hair growth adjusting light irradiation device that irradiates a light irradiation object with light for adjusting hair growth from the light irradiation port 3, and surrounds the light irradiation port 3. A light blocking plate 5 for preventing light leakage, a guide light emitting unit 7 for emitting a guide light 6 for positioning the light R from the light irradiation port 3 at the irradiation position A of the light irradiation object, and It is characterized by having.

  By setting it as such a structure, since the irradiation position A to which the light R for hair growth suppression is irradiated with the guide light 6 can be confirmed in advance, it is possible to perform light irradiation to the irradiation position A of the light irradiation object. it can. Accordingly, since the light leakage prevention light shielding plate 5 surrounding the light irradiation port 3 is provided, the irradiation position A of the light R can be quickly and accurately grasped, so that the light is continuously and repeatedly applied to the same place. Excessive irradiation such as irradiation with R, omission of irradiation, and the like can be prevented. Further, without applying a photosensitive agent, the irradiated surface can be grasped and irradiation work can be easily performed so as not to overlap.

  In the present invention, light from the light irradiation port can be positioned at the irradiation position of the light irradiation object by the guide light, and therefore, it is possible to prevent excessive light irradiation and omission of light, thereby preventing light leakage surrounding the light irradiation port. A hair-growth adjusting light irradiation device that can improve the safety and work efficiency of light irradiation while providing a light shielding plate for use can be obtained.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  As shown in FIG. 4, the hair growth regulating light irradiation device 1 according to the present embodiment includes an apparatus main body 1 </ b> A whose outer shape is configured by a housing 8 that can be held with one hand.

  At the front end portion of the apparatus main body 1A, a light irradiation unit 2 including a light source 9 that irradiates light R for adjusting hair growth, a reflection plate 20, and a light irradiation port 3 is provided. The light R emitted from the light source 9 is irradiated toward the front B of the light irradiation port 3. The light irradiation port 3 of this example is formed in a rectangular shape that is long in the horizontal direction when viewed from the front.

  A control circuit (not shown) for controlling the light source 9 is provided inside the apparatus main body 1A. The control circuit applies a voltage supplied from the power source to the light source 9 as a high voltage, and appropriately controls on / off of light emission of the light source 9, and operates an operation switch (not shown) provided on the outer surface of the housing 8. Thus, various treatment modes such as hair growth and hair removal by the light source 9 are set. For example, in the hair-growth treatment mode, by irradiating laser light with a relatively low energy density, blood circulation is promoted and pores are opened, and sebum and dirt clogged in the pores are washed to obtain a hair-growth effect. On the other hand, in the hair removal treatment mode, by irradiating a laser beam having a relatively high energy density, the protein growth of hair matrix cells such as body hair is promoted, thereby suppressing hair growth. In addition, you may have only one of hair removal and hair growth.

  In addition, a cylindrical light shielding plate 5 for preventing light leakage is disposed on the outer peripheral side of the light irradiation port 3 of the apparatus main body 1A so as to surround the light irradiation port 3. The light shielding plate 5 protrudes forward B in parallel with the light projection axis direction of the light R from the light irradiation port 3. The front edge of the light shielding plate 5 is a skin contact surface 5 a that can come into contact with the skin 4. The light shielding plate 5 is for preventing light damage to the eyes and the like due to light leakage indicated by an arrow C in FIG.

  In addition, a guide light emitting unit 7 that emits guide light 6 for positioning the light R from the light irradiation port 3 at a desired irradiation position A of the skin 4 is provided on the front end surface of the light irradiation port 3. Yes. Here, as shown in FIG. 1, the four guide light emission parts 7 are provided so that a substantially rectangular shape may be drawn along the outer periphery four sides 3a-3d of the rectangular light irradiation port 3. As shown in FIG. Behind each guide light emitting section 7 is a semiconductor laser 10 that emits laser light having a visible wavelength, and a condensing lens 11 that condenses the laser light to form one strip-shaped guide light 6. A provided guide light generating unit 10A is provided. That is, four guide light generating units 10A are provided corresponding to the four guide light emitting units 7 individually. As the condensing lens 11, when one cylindrical lens 11a is used as shown in FIG. 3A, or as shown in FIGS. 1 and 3B, a collimating lens 11b, a cylindrical lens 11c, and a cylinder Fresnel. The design can be changed as appropriate, such as when using the lens 11d. The strip-shaped guide lights 6 respectively emitted from the four guide light emitting sections 7 coincide with the outline of the light R emitted from the light irradiation port 3, and thus the guide light 6 is converted into the light irradiation port 3. The light guide function of visually observing the light R from the irradiation position A of the skin 4 is exhibited, and it works to compensate for the decrease in the visibility of the irradiation position A by the light shielding plate 5.

  Therefore, when the hair growth adjusting light irradiation device 1 having the above-described configuration is used, the irradiation position A is irradiated with the guide light 6 from the position away from the skin 4 as shown in FIG. Then, as shown in FIG. 4, the skin contact surface 5a of the light shielding plate 5 is applied to the skin 4, and the site to be treated of the skin 4 is positioned in the area surrounded by the skin contact surface 5a. At this time, it is possible to reliably irradiate the irradiation position A of the skin 4 illuminated by the guide light 6 with the light R by emitting intermittent pulsed flash light from the light source 9 of the light irradiation unit 2. In this way, the skin contact surface 5a of the light shielding plate 5 can be applied to the skin 4 while visually confirming the irradiation position A of the skin 4 with the guide light 6, so that the light R applied to the skin 4 by the light shielding plate 5 can be applied. Even if the visibility of the irradiation position A is reduced, the irradiation position A is positioned using the guide light 6 to prevent excessive irradiation such as irradiation of the light R repeatedly over the same location, or loss of irradiation. In addition, without applying a photosensitive agent, it is possible to grasp the surface that has been irradiated, and it is easy to perform irradiation work so as not to overlap, resulting in further improvement in terms of safety and irradiation. The work efficiency is also improved.

  Moreover, in this example, by making the four strip-shaped guide lights 6 into a rectangular shape, it is easy to visually recognize that the area surrounded by the guide lights 6 is an irradiation area of the light R from the light irradiation port 3. There is also an advantage that the irradiation position A of the skin 4 can be easily and accurately grasped by visual observation.
