Abstract
The present disclosure relates to an optical fiber capable of converting a wavelength of a light emitted from a light source and a backlight unit using the same. According to the present disclosure, it is possible to extract a light of a desired wavelength band or a desired color (for example, a white light) by connecting an optical fiber, to which a color conversion material is applied, to a single laser light emitting element that emits a light of a specific wavelength band.
Claims21
An optical fiber, comprising:
- a core portion;
- and
- a cladding portion that covers an outer peripheral surface of the core portion;
- wherein the cladding portion has a plurality of openings extending from an inside toward an outside along an extending direction of the core portion,
- wherein the plurality of openings has a first crevice with which a color conversion material is filled and a second crevice with which a color conversion material is not filled,
- wherein the first crevice and the second crevice are adjacent to each other.
3 more elements
An optical fiber, comprising:
- a core portion comprising a first core with which a color conversion material is filled and a second core with which a color conversion is not filled;
- and
- a cladding portion that covers an outer peripheral surface of the core portion;
- wherein a plurality of openings extending from an inside toward an outside is arranged along an extending direction of the first core and the second core.
1 more element
A backlight unit, comprising:
- a light source that emits light having a single wavelength;
- and
- an optical fiber that converts the single wavelength of the light emitted from the light source and emits the converted light;
- wherein the optical fiber includes:
- a core portion where the light emitted from the light source proceeds;
- and
- a cladding portion that covers an outer peripheral surface of the core portion;
- wherein the cladding portion is arranged with a plurality of openings extending from an inside toward an outside along an extending direction of the core portion,
- wherein the plurality of openings includes a first crevice with which a color conversion material is filled and a second crevice with which a color conversion material is not filled, and
- wherein the first crevice and the second crevice are adjacent to each other.
7 more elements
A backlight unit, comprising:
- a light source that emits light having a single wavelength;
- and
- an optical fiber that converts the single wavelength of the light emitted from the light source and emits the converted light;
- wherein the optical fiber includes:
- a core portion that includes a color conversion material, and where the light emitted from the light source proceeds;
- and
- a cladding portion that covers an outer peripheral surface of the core portion;
- wherein the cladding portion is arranged with a plurality of openings extending from an inside toward an outside along an extending direction of the core portion.
