Light source, light-emitting device, light source for backlight, display device, and method for producing light source
A fluorescent material-sealed sheet includes a plurality of fluorescent sections, an upper sealing section, and a lower sealing section, the plurality of fluorescent sections being sealed by the upper sealing section and the lower sealing section.
1. A light source comprising:
a plurality of fluorescent sections each emitting fluorescent light upon receipt of excitation light from an excitation light source; and
a sealing member, having translucency, for sealing the plurality of fluorescent sections, wherein:
at least two of the plurality of fluorescent sections have respective convex shapes; and
said at least two of the plurality of fluorescent sections are arranged substantially in plane with each other so that uprising directions of the respective convex shapes are identical to each other.
2. The light source as set forth in claim 1 , wherein:
at least one of the plurality of fluorescent sections contains a nanoparticle fluorescent material.
3. A light-emitting device comprising:
a light source recited in claim 1 ; and
an excitation light source recited in claim 1 .
4. A light source for a backlight, comprising:
a light-emitting device recited in claim 3 ; and
a light guide plate for guiding light emitted from (i) the excitation light source and (ii) at least one of the plurality of fluorescent sections.
5. A display device comprising:
a light source for a backlight, recited in claim 4 .
6. A light source comprising:
a plurality of fluorescent sections each emitting fluorescent light upon receipt of excitation light from an excitation light source; and
a sealing member, having translucency, for sealing the plurality of fluorescent sections, wherein:
at least two of the plurality of fluorescent sections have their respective convex parts; and
the at least two of the plurality of fluorescent sections are arranged substantially in plane with each other so that their respective convex parts have identical uprising directions.
7. The light source as set forth in claim 6 , wherein:
at least one of the plurality of fluorescent sections has a plurality of convex parts.
8. The light source as set forth in claim 6 , wherein:
at least one of the plurality of fluorescent sections has a single convex part.
9. The light source as set forth in claim 8 , wherein:
the plurality of fluorescent sections each have a single convex part; and
the convex parts are arranged in a matrix manner.
10. A light source comprising:
a plurality of fluorescent sections each emitting fluorescent light upon receipt of excitation light from an excitation light source; and
a sealing member, having translucency, for sealing the plurality of fluorescent sections, wherein:
the sealing member has at least two convex parts; and
the at least two convex parts are arranged substantially in plane with each other so that they have identical uprising directions.
