Description

Optical treatment equipment for hair

[0001] The present invention relates to an optical hair treatment device for promoting hair growth and regrowth.

[0002] Various types of optical hair treatment devices have been proposed so far.

[0003] For example, Patent Document 1 discloses a hairbrush equipped with a plurality of LEDs that emit light in a direction toward the scalp.

[0005] However, the light emitted from the LED is divergent, which causes a problem of insufficient output.

[0006] The present invention has been made in light of the above circumstances, and an object of the present invention is to provide an optical hair treatment device that is capable of obtaining high-power light.

[0007] In order to solve the above problems, the optical treatment device for hair according to the present invention is characterized by comprising a light source for irradiating light toward the scalp, and a lens for converging the light emitted from the light source toward the scalp.

[0008] The optical hair treatment device according to the present invention can provide high-power light.

[0009] The drawings show specific embodiments of the present invention, including not only essential configurations of the invention but also alternative and preferred embodiments. Fig. 1 is a perspective view of an optical treatment device for hair according to an embodiment of the present invention. Fig. 2 is an exploded perspective view of the optical treatment device for hair. Fig. 3 is an exploded side view of the optical treatment device for hair. Fig. 4 is a front view of the main part of the optical treatment device for hair.

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] In FIG. 1, reference numeral 1 denotes an optical hair treatment device according to one embodiment of the present invention.

[0012] This optical hair treatment device 1 has a main body 4 in which a cylindrical portion 2 and a rectangular tube portion 3 are integrally formed.

[0013] As shown in FIGS. 2 and 3, a cover 5 is attached to the rear side of the cylindrical portion 2 and the rectangular tube portion 3.

[0014] A cylindrical case 6 is screwed onto the front side of the cylindrical portion 2, and the front side of the square tube portion 3 is closed.

[0015] A USB connector mounting portion 7, a switch mounting portion 8, etc. are formed at the bottom of the rectangular tube portion 3.

[0016] Furthermore, a lens member 11 is attached to the cylindrical portion 2 on the case 6 side.

[0017] Furthermore, as shown in Figure 4, on the cylindrical portion 2 side of the cover 5, multiple ultra-narrow band red LEDs (light source) 12 with a wavelength of around 630 nm and a circuit 13 for driving these ultra-narrow band red LEDs (light source) 12 are provided.

[0018] The plurality of ultra-narrow band red LEDs (light source) 12 are arranged at equal intervals on the same circumference.

[0019] In addition, the lens member 11 is provided with a plurality of extremely narrow-angle lenses (lenses) 14, for example 6°, corresponding to these ultra-narrow band red LEDs 12, and is configured to separately converge the light emitted from the plurality of ultra-narrow band red LEDs 12 toward the scalp.

[0020] That is, the plurality of ultra-narrow angle lenses (lenses) 14 are also arranged at equal intervals on the same circumference in correspondence with the ultra-narrow band red LEDs 12 .

[0021] According to the above configuration, the light from the ultra-narrow band red LED 12 having a wavelength of about 630 nm is converged by the extremely ultra-narrow angle lens (lens) 14 of, for example, 6°, so that high-output light can be obtained.

[0022] Furthermore, by placing the front edge of the case 6 against the scalp or hair, light can be directed only to the required area, preventing the light from entering the eyes.

[0023] The disclosure of the present invention described above can be summarized at least as follows.

[0024] In other words, the optical treatment device for hair according to the present invention is characterized by comprising a light source for irradiating light toward the scalp, and a lens for converging the light emitted from the light source toward the scalp.

[0025] The present invention can include at least the following embodiments, which can be adopted separately or in combination with each other.

[0026] (1) The light source is preferably an ultra-narrow band red LED.

[0027] (2) The ultra-narrow band red LED is preferably configured as an ultra-narrow band red LED having a wavelength of around 630 nm.

[0028] (3) It is preferable that the lens is an ultra-narrow angle lens.

[0029] (4) The ultra-narrow angle lens is preferably a 6° ultra-narrow angle lens.

[0030] (5) It is preferable that a plurality of light sources are provided on the same circumference, and a plurality of lenses are provided on the same circumference corresponding to the light sources.
