Abstract
A light-emitting device can be folded in such a manner that a flexible light-emitting panel is supported by a plurality of housings which are provided spaced from each other and the light-emitting panel is bent so that surfaces of adjacent housings are in contact with each other. Furthermore, in the light-emitting device, in which part or the whole of the housings have magnetism, the two adjacent housings can be fixed to each other by a magnetic force when the light-emitting device is used in a folded state.
Claims16
A light-emitting device comprising:
- a flexible light-emitting panel;
- and
- a first housing and a second housing that support the flexible light-emitting panel,
- wherein the flexible light-emitting panel includes a first surface on one side of the flexible light-emitting panel and a second surface on the other side of the flexible light-emitting panel,
- wherein the flexible light-emitting panel is foldable so that a first portion of the first surface and a second portion of the first surface face each other,
- wherein the first housing and the second housing are capable of being fixed to each other by magnetism when the first portion of the first surface and the second portion of the first surface face each other,
- wherein each of the first housing and the second housing comprises a ferromagnet, and
- wherein the ferromagnet is provided in each of the first housing and the second housing so that magnetic poles of an upper surface and a lower surface of each of the first housing and the second housing are opposite to each other and that magnetic poles of the upper surfaces of the first housing and the second housing are opposite to each other.
