OLED development began in 1987. OLEDs can be classified into low-molecular materials and high-molecular materials.Kodak's engineers proposed device structures based on low-molecular-layer laminates.In 1990, three years after low-molecular materials, researchers at the University of Cambridge, Light emission was realized. Since then, research and development has been divided into companies using polymer materials and companies using low molecular materials.

Such an OLED is a current-driven light emitting device, and unlike LCD technology, the OLED is capable of self-emission, can be driven at low voltage, and can be made thin. Unlike the general LCD, the picture quality does not change even when viewed from the side, and since afterimages do not remain on the screen, it is a desirable display type as a moving image display. In addition, the small screen has an advantageous price competitiveness due to the image quality of LCD and simple manufacturing process.

However, the disadvantage of OLED is that it is not easy to increase the lifespan and enlarge the display panel. Efforts have been made to develop the life of the organic light emitting material from 30 million hours to more than 50 million hours, and the size of the organic light emitting material is continuously being researched and developed.

(First embodiment)

1 is a view showing a plan view of a lighting device in which lighting panels 200 and 210 are inserted and supported in a lighting panel support structure 100, according to a first embodiment of the invention, and FIG. 2 is FIG. 1. Is a side view of the lighting device shown in FIG. 1 when viewed in the A direction, FIG. 3 is a perspective view of the lighting device shown in FIG. 1, and FIG. 4 is a lighting panel when cut in the BB ′ plane in FIG. 3. 5 is a cross-sectional view from above of an example of the support structure, and FIG. 5 is a cross-sectional view from above of another example of the lighting panel support structure when cut to the BB ′ plane in FIG. 3.

Hereinafter, the first embodiment will be described with reference to FIGS. 1 to 5.

As shown in the drawings, the lighting apparatus according to the first embodiment of the present invention, the lighting panel 200, 210, and the lighting panel insertion portion is inserted and supported as described above, and the lighting panel 200, 210 and The lighting panel supporting structure 100 including the first electrode contact portion and the second electrode contact portion electrically contacting the first electrode (not shown) and the second electrode (not shown) of the lighting panel 200 or 210, respectively. It is made to include.

Here, the lighting device is not only a lighting device used for a living room, a kitchen, a bedroom, a bathroom at home, but also a lighting device, a street lamp, and the like used in a commercial facility such as a ceiling lamp or a restaurant of an office or a factory for commercial use. Applicable

In addition, the lighting panel 200 and 210 herein may be an exemplary OLED lighting panel that is easy to apply to a surface light source, but may be an LED lighting panel or another lighting panel. Hereinafter, the present invention will be described on the assumption that the lighting panels 200 and 210 are OLED panels.

Here, the OLED device used in the lighting panels 200 and 210 is composed of a substrate, an anode layer, an organic material layer, and a cathode layer, and the organic material layer is generally formed in a thin film structure. In the case of using a high molecular organic material, the organic material layer generally has a two-layer structure of a light emitting layer and a hole injection layer. On the other hand, in the case of using a low molecular organic material, the organic material layer includes a hole injection layer, a hole transport layer, a light emitting layer, and a hole block layer. It is common to have a multilayered structure, such as the 5-layered structure of an electron carrying layer.

In addition, it is preferable that the substrate is generally made of glass, and the grid on the substrate is in contact with the anode layer, and serves to lower the electrical resistance value of the anode layer when connecting the anode layer to the wiring part of the driving device for lighting. Do it. The grid is usually a metal with a smaller resistance value than the anode layer, which will be chromium (Cr), copper (Cu), molybdenum (Mo), nickel (Ni), aluminum (Al), silver (Ag) or gold (Au). Can be. The grid may be formed by a process such as deposition on a substrate, application of photosensitive photoresist, development, etching, or the like.

The anode layer is an anode electrode corresponding to the anode of an OLED device, and the material is transparent such as indium tin oxide (ITO) or indium zinc oxide (IZO) having a small surface resistance and good permeability. Conductive materials can be used. By forming the anode layer on the grid, the resistance of the anode layer is lowered, and then the power consumption and driving voltage are lowered when driving the OLED device by connecting to an external driving circuit, thereby improving the electrical characteristics of the device.

The organic material layer is formed on top of the anode layer and emits light in the OLED device. In order to increase luminous efficiency, a hole injection layer (HIL), a hole transport layer (HTL), and an emitting material layer are formed. EML), an Electron Transfer Layer (ETL), an Electron Injection Layer (EIL), etc., are sequentially formed. Organic materials used as the organic material layer are Alq3, TPD, PBD, m-MTDATA, TCTA and the like.

In addition, a cathode layer is deposited on the organic material layer. The material for forming the negative electrode layer may be made of any one metal or two or more alloys selected from aluminum, copper, silver, or lithium fluoride (LiF).

In addition, a protective film is formed to seal the anode layer, the organic material layer, and the cathode layer to be included therein. The protective film is for encapsulation to protect the organic layer from moisture or oxygen, preferably glass or metal, and may be passivated with a thin film.

Since the first electrode and the second electrode of the lighting panel of the present invention are sealed so that the protective film is contained inside the anode layer, the organic layer, and the cathode layer, the first electrode terminal and the second electrode terminal are drawn out of the protective film. It is preferred to be formed in the form.

On the other hand, the structure of an OLED panel used here can use any one or more of a bottom emission structure, a top emission structure, and a double-sided emission structure.

The bottom emission structure emits light from the side of the TFT substrate using a transparent anode, and since the TFT and the wiring are opaque portions, only the portion where the TFT or wiring is not formed can emit light. There was a problem that the area was narrow.

The top emission structure proposed to solve this problem emits light to the upper side where the TFT is not formed by using a transparent cathode. Thus, since light is emitted without using a TFT substrate, it is possible to emit light regardless of the arrangement of TFTs or wirings, and the light emitting area can be widely used. In particular, the top emission structure is advantageous for large displays requiring high brightness.

Meanwhile, the lighting panel inserting portion is a structure in which the lighting panel is inserted to be supported by the lighting panel support structure, and when the lighting panel 200 is inserted in the A direction shown in FIG. 1, as shown in FIGS. 2 and 3.

That is, in FIGS. 1 to 3, when the lighting panel is inserted into the lighting panel inserting portion, the lighting panel support structure supports the lighting panel from three sides, but for preventing the lighting panel from leaving the other surface. It may be configured to further include a means for fastening the lighting panel insert.
