Particularly useful as light emitting members for building sign lamps, advertising signs, illuminations, figurines, lighting fixtures, etc. using the luminous effect of electroluminescence (hereinafter referred to as EL). Regarding application.

In EL, the luminescent material is divided into an inorganic material and an organic material, and has respective characteristics. Organic EL is useful for video images such as televisions because it can easily emit light with high brightness, and inorganic EL is useful for illumination because of its wide optical bandwidth, and developments utilizing these features are advancing. While organic EL has a short lifetime and light emission due to a large area is not stable, inorganic EL has a long life and can stably emit light with a large area. At present, inorganic EL is more practical. And it seems that application products with a relatively simple structure are on the market.

Problems to be solved by the invention

At the present time, the use of sheet materials by organic and inorganic EL that emit surface light is limited to planar use, and in order to construct a three-dimensional and complicated structure. Requires a large amount of the sheet material that is cut and the arrangement of the electrodes is complicated.

The three-dimensional structure is formed with a very thin, light and simple mechanism, and the light emitting surface can be confirmed from any direction. It was considered whether a three-dimensional light-emitting structure using the sheet material that would not give an excellent effect.

As a result, a structure using the sheet material, which forms the following three-dimensional light emitting structure, was created.

Means for solving the problem

As an embodiment of the present invention, it is a three-dimensional light emitting structure of a sheet material made of organic and inorganic EL that emits circular surface light, and is determined at an appropriate distance from the approximate center defined on the surface of the sheet material. Draw a small circle and a great circle centered on the center, starting from one point on the small circle and ending on a point on the great circle The sheet is divided between the start point and the end point by making an arc-shaped cut that does not require a uniform curvature between the start point and the end point. And

In the three-dimensional light emitting structure according to the present invention, the sheet material is deformed so as to be stretchable by stretching the surface having the cuts while twisting up and down by pulling the center portion and the outer peripheral portion apart by gravity or a support. It is characterized by that.

The three-dimensional light emitting structure of the present invention is characterized in that a double-sided light emitting function is realized by bonding two sheets of the single-sided sheet material, and a power supply terminal is provided at an appropriate location.

The three-dimensional light emitting structure of the present invention is characterized in that a power supply terminal is provided at an appropriate location for the sheet material that emits light on both sides.

In addition, if more advanced inorganic and organic EL sheet materials can be used due to future technological advances, it can be used in the present invention.

Effect of the invention

It is an embodiment of the invention of the present application, and is suitable inward from the starting point and the outer peripheral edge determined at an appropriate distance from the approximate center determined on the surface of the sheet material by inorganic and organic EL that emits circular surface light. Draws a small circle and a great circle centered on the center , that is , the end point determined by the distance, and has a curvature between the start point and the end point that starts at one point on the small circle and ends at one point on the great circle. By making arc-shaped cuts that do not need to be the same, the sheet is divided between the start point and the end point, and a plurality of the cuts and the surfaces that do not contact or intersect with each other are stretched while twisting up and down, so Therefore, it is possible to provide a three-dimensional light emitting structure that can be stretched and deformed without applying excessive stress to the surface.

The three-dimensional light-emitting structure of the present invention can provide portable lighting equipment, sign lighting equipment, illuminations, figurines, and the like by using features that easily return to a flat state and are lightweight.

In addition, when handled as a product, a small occupancy ratio is obtained by the above-described characteristics and the movement is easy, so that the cost during storage and transportation can be reduced.
