Claim 11:
12. A light irradiating toothbrush comprising:
a grip;
a head operatively coupled to the grip, wherein the head includes a detachable bristle plate in which brushing bristles made of at least one waveguide are disposed; and
a light source unit disposed inside the head and under the bristle plate that includes a plurality of light sources radiating light through the waveguides of the brushing bristles, wherein the light source unit includes a first light source radiating short-wavelength light and a second light source radiating long-wavelength light, the short-wavelength light source and the long-wavelength light source being disposed at different distances from the bristle plate, in accordance with the magnitude of the wavelengths,
further wherein the plurality of light sources is a set of light sources including a first sub-set that includes at least one first light source radiating short-wavelength light, and a second sub-set that includes at least one second light source radiating long-wavelength light, and
the light sources of the light source unit are alternately arranged under the bristle plate,
wherein the light irradiating toothbrush further comprising a bristle support plate having a plurality of bristle insertion holes in which the plurality of bristles are inserted such that the bristle support plate supports the bristles at least partially inserted into the bristle insertion holes;
a waterproof plate coupled to a lower side of the bristle support plate; and
an optical means disposed on the waterproof plate for condensing or dispersing the light traveling from the lower side of the waterproof plate toward the bristles.
