Abstract
Official abstract text for this publication.
Provided is a luminescent wheel for a projector, which has a novel structure in which a phosphor layer is hard to break even if its thickness is reduced; a manufacturing method therefor; and a light emitting device for a projector. A luminescent wheel for a projector includes: a phosphor layer (11) which has a first principal surface (11a) and a second principal surface (11b) located on an opposite side to the first principal surface (11a) and is capable of being excited by the entry of excitation light to emit fluorescence; a first glass layer (12) provided on the first principal surface (11a) of the phosphor layer (11); and a second glass layer (13) provided on the second principal surface (11b) of the phosphor layer (11).
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a luminescent wheel for a projector including a phosphor layer which has a first principal surface and a second principal surface located on an opposite side to the first principal surface and is capable of being excited by entry of excitation light to emit fluorescence, a first glass layer provided on the first principal surface of the phosphor layer so as to be in contact with the first principal surface, and a second glass layer provided on the second principal surface of the phosphor layer so as to be in contact with the second principal surface, the method comprising the steps of: producing a laminate in which a second green sheet to be the phosphor layer is laid on top of a first green sheet to be the first glass layer and a third green sheet to be the second glass layer is laid on top of the second green sheet; and firing the laminate to form the first green sheet, the second green sheet, and the third green sheet into the first glass layer, the phosphor layer, and the second glass layer, respectively. 2. The method for manufacturing the luminescent wheel for a projector according to claim 1 , wherein the laminate has a wheel shape. 3. The method for manufacturing the luminescent wheel for a projector according to claim 1 , further comprising the step of processing the fired laminate into a wheel shape. 4. The method for manufacturing the luminescent wheel for a projector according to claim 1 , further comprising the step of chemically strengthening the fired laminate.
