Abstract
The utility model discloses an OLED lighting device with adjustable colors, and relates to the field of OLED lighting. The device comprises an OLED panel and a voltage regulation device connected with electrodes of the OLED panel, wherein the OLED panel comprises a substrate and a luminescent layer disposed on the substrate. The luminescent layer comprises a plurality of layers of luminescent organic films, and the light color of each layer of luminescent organic film is different. Thus, when voltage of an external power source changes, electrons and holes of the OLED lighting device can combine with different luminescent organic films and give out light, further achieving an objective that the OLED lighting device emits light in different colors.
Description
Technical field
The utility model relates to the OLED(Organic Light Emitting Diode) lighting field, relate in particular to a kind of OLED lighting device of adjustable color.
Background technology
The main using light source of illumination market has incandescent lamp, fluorescent lamp at present, and the LED(light-emitting diode of greatly developing at present) illumination, above lighting device is all point-source of light or line source, in the actual illumination process, the subject matter existed is that low, the luminous color of luminous efficiency is difficult to adjust, environment is had to pollution and the heat radiation problems such as not smooth, therefore, the OLED(Organic Light Emitting Diode) be widely used.OLED be a kind of luminous evenly, area source that space hold is few because it is with regard to the energy-conservation and feature of environmental protection, be therefore a kind of Healthy Lighting, in addition, OLED can be used as the flexible light device and receives the concern of each side in recent years, and has dropped into a large amount of research work.
The OLED lighting device mainly comprises substrate, be disposed with anode electrode layer, hole transmission layer, luminescent layer, electron transfer layer and negative electrode layer on substrate, the phosphorescence organic film that described luminescent layer is a kind of illuminant colour, as blue, red etc., when supplying power to appropriate voltage, anodal hole and negative electrode electric charge will combinations in luminescent layer, produce bright.In existing illumination market, the illuminating device adjustable for color also has very large demand space, and such as Landscape Lighting, stage illumination, lighting, advertising lighting and room lighting etc., in order to reach certain effect, needs illuminating device can continue to change different colors.In existing illuminating lamp, due to the impact that is subject to its principle of luminosity, reach and continue different color variable color illuminating effects, can cause structure very complicated.
The utility model content
For above-mentioned defect or deficiency, the utility model provides a kind of OLED lighting device of adjustable color.
To achieve the above object, the main device of the utility model is:
Comprise oled panel and the voltage regulating device be connected with the oled panel electrode, wherein,
Described oled panel comprises substrate, and is arranged at the luminescent layer on substrate, and described luminescent layer comprises the luminous organic film of some layers, and the glow color difference of every layer of luminous organic film.
Described every layer of luminous organic film is the luminous organic film of the phosphorus formed by evaporation.
The thickness of described luminous organic film is
.
The regulation voltage scope of described voltage regulating device is 0-20V.
The utility model is set to the luminous organic film of multilayer by the luminescent layer in the OLED lighting device, and every layer of luminous organic film glow color difference, make the OLED lighting device when external supply voltage is regulated conversion, electronics can be in conjunction with luminous on different luminous organic films from hole, and then reach the purpose that the OLED lighting device sends different colours light, in addition, this OLED lighting device has simple in structure, low cost of manufacture, advantage easy to use.
The accompanying drawing explanation
Fig. 1 is the OLED illuminator structure schematic diagram of a kind of adjustable color of providing of the utility model.
In figure, 1 is oled panel, and 2 is voltage regulating device, and 3 is substrate, and 4 is luminescent layer, and 5 is organic film, and 6 is anode electrode layer, and 7 is hole transmission layer, and 8 is cathode electrode.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Shown in figure 1, the utility model provides a kind of OLED of adjustable color at lighting device, comprise oled panel 1 and the voltage regulating device 2 be connected with oled panel 1 electrode, the regulation voltage scope of voltage regulating device is set as 0-20V, described oled panel 1 comprises substrate 3, substrate 3 is reached the standard grade and is provided with anode electrode layer 6, be provided with hole transmission layer 7 on anode electrode layer 6, be provided with luminescent layer 4 on hole transmission layer 7, described luminescent layer 4 comprises the luminous organic film 5 of some layers, and the glow color difference of every layer of luminous organic film 5, described every layer of luminous organic film is the luminous organic film of the phosphorus formed by evaporation, detailed process is: will pass through vapour deposition method doped with the luminous organic material of the phosphorescence of different glow colors, in layer uniform evaporation is on substrate 3, and every layer of 5 of luminous organic film sends a kind of color, exemplary, the ground floor of luminescent layer 4 is set to the red luminous organic material of mixing phosphorescence, the second layer is set to glow color for the yellow and red luminous organic material of phosphorescence that mixes, the 3rd layer is set to glow color is yellow luminous organic material of mixing phosphorescence etc., it should be noted that, the needs that organic film 5 colors on luminescent layer 4 and the number of plies can have more the user are arranged, but, the thickness of described luminescent layer is
, after evaporation completes luminescent layer 4, at luminescent layer 4, electron transfer layer 8 is set, cathode electrode 9 is set on electron transfer layer 8 again.
The utility model operation principle:
By the voltage regulating device 2 be connected with oled panel 1 electrode, when supplying power to appropriate voltage, anodal hole and negative electrode electric charge will be in luminescent layer combination in the different organic film 5 of glow color, send light, when regulation voltage adjusting device 2 again, electric current, with change in voltage, changes the position of anodal hole and negative electrode charge bonded, and then sends different lights.
