摘要:
The present invention can further increase the efficiency of light extraction from the light exit surface of a light-emitting device. A cell (10) for a light-emitting device includes: a first main wall (10a) and a second main wall (10b) which are disposed facing each other with a distance therebetween; and a sidewall (10c). The sidewall (10c) connects the first main wall (10a) and the second main wall (10b). The sidewall (10c) defines, together with the first and second main walls (10a, 10b), an internal space (10A) into which a luminescent substance is to be encapsulated. A portion of the sidewall (10c) located laterally of the internal space (10A) is white.
摘要:
An optical waveguide member is inserted into a tubular member. The tubular member is elongated with heating and fusion-bonded to the optical waveguide member. Thus, a formed body is obtained. The formed body is cut into a predetermined length to obtain an optical waveguide member. The tubular member is preferably made of a crystallized glass with crystals deposited therein at least in the state of the formed body.

Provided are a long-life light emitting device less likely to degrade luminescence properties over time, a method for manufacturing the same, and a cell for a light emitting device used for the same. A light emitting device 1 includes a cell 10 and a luminescent material encapsulated in the cell 10. The cell 10 includes a pair of glass sheets 12 and 13 and a glass-made fused part 14a. The pair of glass sheets 12 and 13 are disposed to face each other with a space therebetween. The fused part 14a is disposed between respective peripheral portions of the pair of glass sheets 12 and 13. The fused part 14a is fused to each of the pair of glass sheets 12 and 13.

Provided is a method whereby a cell for a light-emitting device less variable in the thickness of the internal space can be suitably produced with high production efficiency. A glass-made fused part forming element (25) is provided in a grid-like pattern between a pair of glass sheet base materials (21, 24) disposed facing each other with a space therebetween. The fused part forming element (25) is fused to each of the pair of glass sheet base materials (21, 24) to produce a cell base material (30) having a grid-like fused part (26). The cell base material (30) is cut along each of row and column directions of the grid-like fused part (26) to produce a plurality of light-emitting devices (1). Portions off the grid-like fused part forming element (25) along a first direction are formed of glass ribbons (22) and portions of the grid-like fused part forming element (25) along a second direction are formed of glass paste.

Provided are a method for producing a phosphor-encapsulating capillary tube in which, when a phosphor is encapsulated thereinto, fluorescence from the phosphor is less likely to leak from an end of the capillary tube; and such a phosphor-encapsulating capillary tube. One end portion 10A of an elongate glass capillary tube 10 having an outer shape of a transverse cross-section elongated in a width direction thereof is heated until the one end portion 10A of the glass capillary tube 10 has been melted, integrated, and thus sealed.
摘要:
A preliminary member of an optical device component with optical fiber comprises a long capillary tube made of glass or crystallized glass and an optical fiber which is fixed in the inner hole of the long capillary tube with adhesive. The overall length of the preliminary member is a plurality of times that of the optical device component or more. A plurality of short capillary tubes with optical fibers are formed by cutting the preliminary member. Thereafter, by polishing both end faces of the short capillary tube with optical fiber, an optical device component can be obtained.
