Problems solved by technology

[0007] However, even in the case of a lighting device that combines a blue light-emitting diode with a yellow phosphor to output white light, the fluorescent material itself that emits yellow light has poor luminous efficiency, and thus there is a limit in improving the luminous efficiency of the lighting device

Embodiment Construction

[0025] Hereinafter, the present disclosure will be described in detail with reference to the accompanying drawings.

[0026] The present disclosure provides a lighting device including an organic light emitting device made of an organic material, rather than a lighting device including an inorganic light emitting device made of an inorganic material.

[0027] Compared with inorganic light emitting devices, organic light emitting devices made of organic light emitting materials have relatively good luminous efficiencies in green and red. In addition, organic light-emitting devices have relatively large widths in blue, red, and green emission peaks compared with inorganic light-emitting devices, so the organic light-emitting device has the advantage that its color rendering performance is improved, and the light and light of the light-emitting device Daylight is more similar.

[0028] According to the present disclosure, a lighting device can be manufactured by a roll-to-roll m...

Abstract

The invention provides a lighting apparatus using organic light emitting device and a method of fabricating thereof. The lighting apparatus of the present disclosure may transport a film formed with aplurality of lighting apparatuses between rolls, and place a mask on an entire surface of the film to deposit an organic light emitting material in a state in which a part of the film is blocked to form an organic light emitting layer, and then deposit a metal layer by the same mask to form a second electrode, wherein the organic light emitting layer and the second electrode are not formed in a region where a pad is formed by the mask to open the pad and connect an external signal source thereto. The first electrode may be connected to a first pad and the second electrode may be connected toa second pad to apply a voltage, wherein a part of the organic light emitting layer is laser-etched to form a contact portion, and the second electrode is electrically connected to the second pad.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2016-0182829 filed on December 29, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to a lighting apparatus using an organic light emitting device having a simplified manufacturing process and a manufacturing method thereof. Background technique [0004] In recent years, fluorescent lamps or incandescent lamps are mainly used as lighting equipment. Among them, incandescent lamps have good color rendering index but low energy efficiency, and fluorescent lamps are efficient but low color rendering index and contain mercury, thus having environmental problems. [0005] In order to solve such problems of lighting devices in the related art, in recent years, light emitting diodes (LEDs) have been proposed as lighting devices. Light-emitting diodes are composed o...
