A portable terminal according to an embodiment of the present invention includes the above-described ultraviolet sterilizing device.

According to the present invention, an ultraviolet sterilization apparatus is provided inside the portable terminal, and ultraviolet rays can be sterilized by emitting ultraviolet rays through the ultraviolet lamp, and there is no need to provide a separate sterilization apparatus during movement, thereby increasing convenience. In addition, it is possible to sterilize not only the portable terminal but also other objects, thereby increasing efficiency.

Further, according to the present invention, by disposing an ultraviolet lamp on the side of the light guide plate, the entire area to be sterilized of the portable terminal device can be sterilized by using a light guide plate, a diffusion sheet, or the like, for the ultraviolet light emitted from a small amount of the ultraviolet lamp. Miniaturization and production costs can be reduced.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view showing an ultraviolet sterilizing apparatus for a portable terminal according to an embodiment of the present invention.

Referring to FIG. 1, an ultraviolet sterilizer for a portable terminal according to the present invention may include an ultraviolet lamp 10, a light guide plate 20, and a diffusion sheet 30 that emit ultraviolet light.

The ultraviolet lamp 10 emits ultraviolet rays, and the emitted ultraviolet rays have a short wavelength and high energy, and thus have a sterilizing function. Therefore, the ultraviolet lamp 10 that emits ultraviolet rays may be disposed in an area to be sterilized and sterilize the area.

On the other hand, since the portable terminal is becoming smaller and smaller, it is difficult to install an ultraviolet lamp over the entire portion to be sterilized. Thus, the ultraviolet lamp 10 that emits ultraviolet rays may be disposed in a narrower space than the region to be sterilized.

However, according to the exemplary embodiment, a plurality of ultraviolet lamps 10 may be provided.

The light guide plate 20 emits ultraviolet rays which are emitted from the ultraviolet lamp 10 and incident on the side surface to the lower side. In detail, the ultraviolet light emitted from the ultraviolet lamp 10 is incident, and is emitted downward through refraction, reflection, scattering, and the like.

That is, the ultraviolet rays emitted from the ultraviolet lamp 10 may emit ultraviolet rays in the entire region arranged over the light guide plate 20. In this process, ultraviolet rays are emitted to the diffusion sheet 30, which will be described later, disposed below the light guide plate 20.

As described above, due to the miniaturization of the portable terminal, the sterilizing effect can be obtained over the entire area to be sterilized by the light guide plate 20 by using the light guide plate 20.

The diffusion sheet 30 is disposed under the light guide plate 20 to diffuse ultraviolet rays emitted from the light guide plate 20. In particular, the diffusion sheet 30 is capable of sterilization by diffusing ultraviolet rays over a wide area to be sterilized, thereby improving sterilization efficiency.

According to the exemplary embodiment, the reflective sheet 40 disposed above the light guide plate 20 may be used. This will be described in FIG. 2 to be described later.

Referring to FIG. 2, the ultraviolet sterilizer for a portable terminal according to the present invention may include an ultraviolet lamp 10, a light guide plate 20, and a reflective sheet 40 that emit ultraviolet light.

The reflective sheet 40 is disposed above the light guide plate 20 to reflect ultraviolet rays downward. In detail, the reflective sheet 40 may reflect ultraviolet rays leaked to the upper side of the light guide plate 20 downward to reduce the consumption of ultraviolet rays, thereby improving sterilization efficiency.

3 is a cross-sectional view showing an ultraviolet sterilizing apparatus for a portable terminal according to another embodiment of the present invention. Description of the same elements as those described with reference to FIGS. 1 and 2 will be omitted.

Referring to FIG. 3, the ultraviolet sterilizer for a portable terminal according to the present invention may include an ultraviolet lamp 10, a light guide plate 20, a reflective sheet 40, and a diffusion sheet 30 that emit ultraviolet light. .

Ultraviolet rays are emitted from the ultraviolet lamp 10. The light guide plate 20 emits ultraviolet rays which are emitted from the ultraviolet lamp 10 and incident on the side surface. In this case, the reflective sheet 40 disposed on the upper side of the light guide plate 20 may reflect ultraviolet rays leaked to the upper side of the light guide plate 20 to the lower side to reduce the consumption of ultraviolet rays. Alternatively, the reflective sheet 40 may reflect the ultraviolet rays emitted from the ultraviolet lamp 10 and directly incident on the reflective sheet 40 to the lower side.

Therefore, the light guide plate 10 emits not only ultraviolet rays incident to the side surface from the ultraviolet lamp 10 but also ultraviolet rays reflected from the reflective sheet 40 to the lower side. The ultraviolet rays emitted downward from the light guide plate 10 are diffused into the region to be sterilized.
