Modes for Carrying Out the Invention

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

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

[0012] This optical treatment device 1 for hair includes 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 back side of the cylindrical portion 2 and the rectangular tube portion 3.

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

[0015] At the bottom of this rectangular tube portion 3, a USB connector attachment portion 7, a switch attachment portion 8, and the like are formed.

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

[0017] Furthermore, on the side of the cylindrical portion 2 of the cover 5, as shown in FIG. 4, a plurality of ultra-narrowband red LEDs (light sources) 12 with a wavelength near 630 nm and a circuit 13 for driving this ultra-narrowband red LED (light source) 12 are provided.

[0018] These plurality of ultra-narrowband red LEDs (light sources) 12 are arranged at equal intervals in a concentric circular shape.

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

[0020] That is, the plurality of narrow-angle lenses 14 are also arranged at equal intervals on the same circumference corresponding to the ultra-narrowband red LEDs 12.

[0021] According to the above configuration, since the light of the ultra-narrowband red LED 12 with a wavelength near 630 nm is converged by an extremely narrow-angle lens (lens) 14 of, for example, 6°, high-output light can be obtained.

[0022] In addition, by applying the front edge of the case 6 to the scalp or hair, light can be delivered only to the necessary places, and the entry of light into the eyes can be prevented.

[0023] The disclosure regarding the present invention described above can be summarized at least in the following matters.

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

[0025] The above-described present invention can include at least the following embodiments. These embodiments can be adopted separately or in combination with each other.

[0026] (1) The light source is preferably composed of an ultra-narrowband red LED.

[0027] (2) The ultra-narrowband red LED is preferably composed of an ultra-narrowband red LED with a wavelength near 630 nm.

[0028] (3) The lens is preferably composed of an ultra-narrow-angle lens.

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

[0030] (5) The light source is preferably provided on a plurality of same circumferences, and the lens is preferably provided on a plurality of same circumferences corresponding to the light source.
