摘要： A lighting apparatus of the present disclosure includes an organic light emitting diode formed by a first electrode, an organic light emitting layer, and a second electrode on a first substrate and configures the first electrode by a transparent conductive material having an electrical resistance of 2800 to 5500Ω in each pixel. Therefore, even though the first electrode and the second electrode are in contact with each other to remove the electrical resistance by the organic light emitting layer in the pixel, the overcurrent is suppressed from being applied to the pixel by the electrical resistance of the first electrode. Further, at least one conductive pattern formed of a low electrical resistance transparent conductive material which is connected to the first electrode in the pixel is disposed to suppress the degradation of the luminance by the first electrode having a high electrical resistance.

摘要： Examples of a lighting and display type luminaire use relatively transparent lighting devices. In such a luminaire, a light transmissive element of the lighting device is coupled to an output of a display device. For example, an edge lit lighting device includes an optical waveguide and one or more illumination light sources coupled to supply light to/through a surface along an edge or periphery of the waveguide. The waveguide allows emission of illumination light through a front surface. A display is coupled to a back surface of the waveguide. During display operations, the waveguide is sufficiently transparent to allow image display light to pass through the waveguide for emission through the front surface of the waveguide. Another example utilizes a light transmissive OLED (organic light emitting diode) panel as the relatively transparent lighting device.
