Light-emitting module, light-emitting panel, and lighting device

摘要

An object is to provide a light-emitting module in which a light-emitting element suffering a short-circuit failure does not cause wasteful electric power consumption. Another object is to provide a light-emitting panel in which a light-emitting element suffering a short-circuit failure does not allow the reliability of an adjacent light-emitting element to lower. Focusing on heat generated by a light-emitting element suffering a short-circuit failure, provided is a structure in which electric power is supplied to a light-emitting element through a positive temperature coefficient thermistor (PTC thermistor) thermally coupled with the light-emitting element.

1. A light-emitting panel comprising:
a substrate; a first light-emitting module comprising:
a first light-emitting element; anda first positive temperature coefficient thermistor; and a second light-emitting module comprising:
a second light-emitting element; anda second positive temperature coefficient thermistor, wherein the first light-emitting module and the second light-emitting module are electrically connected in series and adjacent to each other, wherein the first light-emitting element and the second light-emitting element are located over the substrate, wherein the first light-emitting element and the second light-emitting element each include a first electrode, a second electrode, and a layer including a light-emitting organic compound interposed between the first electrode and the second electrode, wherein the first light-emitting element is configured to be supplied with electric power through the first positive temperature coefficient thermistor, and wherein the second light-emitting element is configured to be supplied with electric power through the second positive temperature coefficient thermistor.
