Abstract
(EN)
This phosphor substrate (30) has at least one light-emitting element (20) mounted on one surface thereof, and comprises an insulating substrate (32), an electrode layer (34) which is disposed on one surface of the insulating substrate (32) and is joined to the light-emitting element (20), and a phosphor layer (36) which is disposed on one surface of the insulating substrate (32) and includes a phosphor for which the emission peak wavelength when excited by light emitted by the light-emitting element (20) is in the visible light range. A joining surface (34A1) joined to the light-emitting element (20), said joining surface being on the surface of the electrode layer (34) that faces outward in the thickness direction of the insulating substrate (32), is positioned further outward in the aforementioned thickness direction than a non-joining surface (34B1) that is the surface other than the joining surface (34A1), and at least a portion of the phosphor layer (36) is disposed around the joining surface (34A1).

La présente invention concerne un substrat de luminophore (30) sur la surface duquel se trouve un élément électroluminescent (20), et comprenant un substrat isolant (32), une couche d'électrode (34) qui est disposée sur une surface du substrat isolant (32) et est reliée à l'élément électroluminescent (20), et une couche de luminophore (36) qui est disposée sur une surface du substrat isolant (32) et comprend un luminophore dont la longueur d'onde de pic d'émission lorsqu'elle est excitée par la lumière émise par l'élément électroluminescent (20) est dans la plage de lumière visible. Une surface de jonction (34A1) est reliée à l'élément électroluminescent (20), ladite surface de jonction se trouvant sur la surface de la couche d'électrode (34) qui est orientée vers l'extérieur dans le sens de l'épaisseur du substrat isolant (32), est positionnée davantage vers l'extérieur dans le sens de l'épaisseur susmentionné qu'une surface de non-jonction (34B1) qui est la surface autre que la surface de jonction (34A1), et au moins une partie de la couche de luminophore (36) est disposée autour de la surface de jonction (34A1).
