Title:
蛍光体基板、発光基板及び照明装置
Document Type and Number:
Japanese Patent JP7425750
Kind Code:
B2
Abstract:
A phosphor substrate of the invention having at least one light emitting element mounted on one surface, includes an insulating substrate, at least one electrode pair disposed on one surface of the insulating substrate and bonded to the light emitting element, and a phosphor layer which is disposed on one surface of the insulating substrate and includes a phosphor in which a light emission peak wavelength, in a case where light emitted by the light emitting element is used as excitation light, is in a visible light region, in which a bonded surface of a surface of the at least one electrode pair facing an outer side in a thickness direction of the insulating substrate, the bonded surface being bonded to the light emitting element, is positioned further on the outer side in the thickness direction than a non-bonded surface which is a surface other than the bonded surface, and at least a part of the phosphor layer is disposed around the bonded surface of the one surface.
