Abstract:
There is provided a luminescent light emitting device including a mirror layer, a luminescent material plate that is formed on one surface side of the mirror layer, and a conductive thin wire film in which a conductive thin wire is disposed and that lies on the other surface side of the mirror layer, in that luminescent light that is emitted by the luminescent material plate is emitted to the front that is one surface side of the luminescent material plate by the mirror layer, and damage done to the luminescent material plate is detected by a disconnection of the conductive thin wire.
