有機電激發光白光照明裝置 Organic electric excitation white light illumination device

本發明涉及一種有機電激發光白光照明裝置，尤其是利用具有較高能量的光線對螢光粉進行激發，而混合產生白光。 The invention relates to an organic electroluminescent white light illumination device, in particular to ignite a phosphor by using light having a higher energy, and mixing to generate white light.

在傳統發光白光照明裝置的結構中，通常是使用具有紅光發光元件、綠光發光元件以及藍光發光元件來進行混光而形成白光，也就是所謂的「三原光發光法」，或者是利用紅、綠、藍三原光之螢光粉，受到光能或電能的驅動，而產生紅光、綠光、藍光在混成白光。 In the structure of a conventional illuminating white light illuminating device, it is common to use a red light emitting element, a green light emitting element, and a blue light emitting element to perform light mixing to form white light, that is, a so-called "three original light illuminating method", or use red The phosphors of the three primary light, green and blue, are driven by light energy or electric energy, and red, green and blue light are mixed into white light.

上述的方式，「三原光發光法」通常需要分別製作三種發光元件的步驟，雖然製作方式已經量產化，但是需要三道步驟製作，因此整體製程時間較長，另外，藉由三種螢光粉的方式，則是因為螢光粉成本昂貴，因此，需要一種製程簡單、節省成本的白光發光照明裝置。 In the above-described manner, the "three original photoluminescence method" generally requires a step of separately fabricating three kinds of light-emitting elements. Although the production method has been mass-produced, it requires three steps of fabrication, so that the overall process time is long, and in addition, three types of phosphor powder are used. The way is because the fluorescent powder is expensive, and therefore, a white light emitting illumination device with simple process and cost saving is needed.

本發明的主要目的是提供一種有機電激發光白光照明裝置，該有機電激發光白光照明裝置包含：基板、透明電極層、電激發光層、金屬電極層以及至少一光激發光層，其中電激發光層，受電能激發時，發出一電激光朝向基板的方向發出；至少一光激發光層包含複數個螢光粉，且具有20~80%的孔隙率，螢光粉為黃色螢光粉、及/或紅光螢光粉及綠光螢光粉的混合，及/或紅光、綠光及藍光螢光粉的混合，當受到來自電激發光層的光線時，受激發而發出黃光，及/或紅光及綠光，及/或紅光、綠光及藍光，而該電激光穿過光激發層時，穿過螢光粉間的間隙的電激光與該等螢光粉所發出的光線混合形成白光，亦或使各螢光粉受激發所發出的光線混合成白光。 The main object of the present invention is to provide an organic electroluminescent white light illumination device comprising: a substrate, a transparent electrode layer, an electroluminescent layer, a metal electrode layer and at least one photoexcitation layer, wherein Exciting the light layer, when excited by the electric energy, emitting an electric laser to emit in the direction of the substrate; at least one photoexcitation layer comprises a plurality of phosphor powders, and has a porosity of 20 to 80%, and the phosphor powder is yellow phosphor powder And/or a mixture of red and green phosphors, and/or a mixture of red, green and blue phosphors, which are excited to emit yellow when exposed to light from the electroluminescent layer Light, and/or red and green light, and/or red light, green light, and blue light, and when the electric laser passes through the photoexcited layer, an electric laser that passes through the gap between the phosphors and the phosphor powder The emitted light is mixed to form white light, or the light emitted by the respective phosphors is mixed into white light.

進一步地，本發明的另一目的是將螢光粉設置於基板內部，更進一步地，可以在基板的另一表面設置一保護層，而將螢光粉設置於該保護層的內部。如此，利用有機電場激發高能量發光層，再以高能量發光層所發出的光線去激發低能量的光激發材料螢光粉，如此能夠利用更方便的方式製作配置白光照明元件的效果。 Further, another object of the present invention is to provide the phosphor powder inside the substrate, and further, a protective layer may be disposed on the other surface of the substrate, and the phosphor powder may be disposed inside the protective layer. In this way, the high-energy light-emitting layer is excited by the organic electric field, and the light emitted by the high-energy light-emitting layer is used to excite the low-energy light-exciting material phosphor, so that the effect of arranging the white light illumination element can be produced in a more convenient manner.
