摘要： Provided is a long-life organic electroluminescent illumination panel which is flexible and, even when a load is applied by bending, impact or vibration, can suppress the occurrence of defects in an electrode layer and an organic layer containing an organic electroluminescent material, and which can suppress the occurrence of dark spots due to short circuiting. This organic electroluminescent illumination panel includes: a pair of electrode layers, at least one of which is transparent, between a flexible film substrate and a flexible film sealing material, at least one of which is transparent; and an organic layer containing an organic electroluminescent material which is sandwiched between the pair of electrode layers. This organic electroluminescent illumination panel has multiple spacers which are disposed on an electrode layer laminated on the flexible film substrate so as to pass through the organic layer and another electrode layer.

摘要： An organic EL device includes an organic EL panel, an ellipsoidal reflector, a phosphor, and a laser. The organic EL panel includes a substrate and at least one organic EL element, and the substrate includes at least one light incident portion on which light is incident from the outside. The ellipsoidal reflector is disposed outside the organic EL panel in such a manner that the phosphor is disposed at a first focal point of the reflector and the light incident portion of the substrate is positioned at a second focal point of the reflector. The laser is disposed outside the organic EL panel in such a manner that the phosphor can be irradiated with a laser beam. Light emitted from the phosphor enters the substrate from the light incident portion. The light emitted from the phosphor that has entered the substrate diffuses in the in-plane direction of the substrate.

摘要： A light emitting element circuit includes a light emitting element (1), a current supply path to the light emitting element (1), a constant current circuit (2) that supplies a current to the light emitting element (1) via the current supply path, and an electric discharge path that discharges an electric charge accumulated at the light emitting element (1) and at a region connected between the both electrodes when the constant current circuit (2) stops a current supply to the light emitting element (1). A light emitting element failure detector (4) that detects a short-circuit of the light emitting element (1) in a light emitting element circuit includes a current instantaneous interruption circuit (5), a voltage detector (60), and a determiner (62). The current instantaneous interruption circuit (5) is arranged on the current supply path different from the electric discharge path and instantaneously interrupts an electric current that the constant current circuit (2) supplies to the light emitting element (1). The voltage detector (60) obtains an output of a voltage Vf between the anode and cathode of the light emitting element (1) during a period of the instantaneous interruption as a measuring object. The determiner (62) determines the existence of a short-circuit from the output.
