Abstract

A method for manufacturing a light-emitting case includes forming a PLED (Polymer Light Emitting Diode) device, disposing the PLED device into a mold, and utilizing the mold to sheathe the PLED device with transparent plastic material in an injection-molding manner. Since the mold has a cavity corresponding to a predetermined shape, the formed transparent plastic material has a geometric appearance corresponding to the predetermined shape.

Claims (24)

1. A method for manufacturing a light-emitting case comprising:

providing a PLED (Polymer Light Emitting Diode) device, the PLED device at least having a light-emitting layer and an electrode set formed on the light-emitting layer;

disposing the PLED device into a mold, the mold having a cavity corresponding to a corrugated shape, and the shape of the PLED device corresponds to the corrugated shape due to the flexibility thereof; and

utilizing the mold to sheathe the PLED device with transparent plastic material in an injection-molding manner;

wherein the formed transparent plastic material has a geometric appearance corresponding to the corrugated shape and us formed as a case structure;

wherein the PLED device is sheathed in the case structure to form the light-emitting case.

2. The method of claim 1 , wherein providing the PLED device at least having the light-emitting layer and the electrode set formed on the light-emitting layer comprises providing the PLED device at least having a plurality of light-emitting blocks.

3. The method of claim 2 , wherein providing the PLED device at least having the plurality of light-emitting blocks comprises providing the PLED device at least having the plurality of light-emitting blocks, each emitting light of one specific color.

4. The method of claim 1 , wherein providing the PLED device at least having the light-emitting layer and the electrode set formed on the light-emitting layer comprises providing the PLED device at least having the light-emitting layer arranged in a specific pattern.

5. The method of claim 1 , wherein disposing the PLED device into the mold having the cavity corresponding to the corrugated shape comprises disposing the PLED device into the mold having the cavity corresponding to a curved-surface shape.

6. The method of claim 1 further comprising utilizing the electrode set to control brightness of the light-emitting layer.

7. A light-emitting case having a PLED, the light-emitting case comprising:

a PLED device comprising:

a light-emitting layer; and

an electrode set electrically connected to the light-emitting layer, the electrode set used for controlling the light-emitting layer to emit light or not; and

a case structure formed with the PLED device in a mold by an injection molding method, the mold having a cavity corresponding to a corrugated shape, the shape of the PLED device corresponds to the corrugated shape due to the flexibility thereof, the formed case structure sheathing the PLED device and having a geometric appearance corresponding to the corrugated shape:

wherein the PLED device is sheathed in the case structure to form the light-emitting case.

8. The light-emitting case of claim 7 , wherein the light-emitting layer comprises a plurality of light-emitting blocks.

9. The light-emitting case of claim 8 , wherein each light-emitting block emits light of one specific color.

10. The light-emitting case of claim 7 , wherein the light-emitting layer is arranged in a specific pattern.

11. The light-emitting case of claim 7 , wherein the corrugated shape has a curved-surface.

12. The light-emitting case of claim 7 , wherein the case structure is made of transparent plastic material.

13. The light-emitting case of claim 12 , wherein the case structure is made of ABS (Acrylonitrile-Butadiene-Styrene) material.

14. The light-emitting case of claim 7 , wherein the electrode set is further used for controlling brightness of the light-emitting layer.
