Description
本發明係有關於一種白光發光二極體模組結構，尤指針對白光混合琥珀光和紅光之一種具有混白光之發光二極體裝置。The invention relates to a white light emitting diode module structure, in particular to a light emitting diode device with white light mixed with amber light and red light.
科技日新月異，有關於照明技術方面更是大幅度的躍進，近年來積極發展有關於發光二極體（Light-Emitting Diode ， LED）此一技術，其為一種能發光的半導體電子元件，透過三價與五價元素所組成的複合光源。此種電子元件早在1962年出現，早期只能夠發出低光度的紅光。及後發展出其他單色光的版本，時至今日，能夠發出的光已經遍及可見光、紅外線及紫外線，光度亦提高到相當高的程度。用途由初時的指示燈及顯示板等；隨著白光發光二極體的出現，近年逐漸發展至被普遍用作照明用途。The technology is changing with each passing day. There is a big leap forward in lighting technology. In recent years, there has been a development of a technology related to Light-Emitting Diode (LED), which is a kind of semiconductor electronic component capable of emitting light. A composite light source composed of pentavalent elements. Such electronic components appeared as early as 1962, and only in the early days were able to emit low-light red light. Later, other versions of monochromatic light were developed. Today, the light that can be emitted has spread to visible light, infrared light and ultraviolet light, and the luminosity has also increased to a relatively high degree. The use of the initial indicator lights and display panels; with the emergence of white light emitting diodes, in recent years has gradually developed to be widely used for lighting purposes.
然而，發光二極體本身是單色光源，而自然界的白光（陽光）的光譜是闊頻帶的，就單以一發光二極體光源所發出之光無法發出多色光，需以其他材料輔助才行，所以LED本身不可能做到就依單一光源發出白光。白光發光二極體是通過發出三原色藍色、綠色及紅色的單色光（R、G、B）或以螢光粉把發光二極體發出的單色光轉化發出白光，使整體光譜含為含有三原色的光譜，刺激人眼感光細胞，使人有看見白光的感覺。However, the light-emitting diode itself is a monochromatic light source, and the spectrum of natural white light (sunlight) is broad-band, and the light emitted by a single light-emitting diode light source cannot emit multi-color light, and needs to be assisted by other materials. OK, so the LED itself is impossible to emit white light according to a single source. The white light emitting diode converts the monochromatic light emitted by the light emitting diode into white light by emitting blue, green and red monochromatic light (R, G, B) of the three primary colors or by using the fluorescent powder, so that the overall spectrum is included. The spectrum containing the three primary colors stimulates the photoreceptor cells of the human eye, giving people the feeling of seeing white light.
就近年來以結合藍光發光二極體、紅光發光二極體和綠光發光二極體便可做出白光發光二極體，這樣產生的白光發光二極體有較廣的色域，而且效率較其他方法高，不過成本相當高。不過，近年生產方面與技術方面的改進下，越來越多產品採用這方法形成發白光之發光二極體模組。In recent years, a white light emitting diode can be formed by combining a blue light emitting diode, a red light emitting diode, and a green light emitting diode, and the white light emitting diode thus produced has a wider color gamut and efficiency. Higher than other methods, but the cost is quite high. However, in recent years, with the improvement of production and technology, more and more products use this method to form a white light emitting diode module.
現在普及的白光發光二極體都採用單一發光單元發出波長較短的光，如藍或紫外光，再用磷光劑把部份或全部光轉化成一頻譜含有綠、紅光等波長較長的光。這種光波波長轉化作用稱為螢光，原理是短波長的光子（藍、紫、紫外光）被螢光物質（如磷光劑）中的電子吸收後，電子被激發（跳）至較高能量、不穩定的激發狀態，之後電子在返回原位時，一部份能量散失成熱能，一部份以光子形式放出，由於放出的光子能量比之前的小，所以波長較長。由於轉化過程中有部份能量化成熱能，造成能量損耗，因此這類白光發光二極體的效率較低。Nowadays, the popular white light emitting diodes use a single light emitting unit to emit light of a shorter wavelength, such as blue or ultraviolet light, and then use phosphor to convert part or all of the light into a spectrum of light having a longer wavelength such as green or red light. . This wavelength conversion of light waves is called fluorescence. The principle is that short-wavelength photons (blue, violet, ultraviolet light) are absorbed by electrons in a fluorescent substance (such as a phosphor), and the electrons are excited (jumped) to higher energy. The unstable excitation state, after the electron returns to the original position, a part of the energy is dissipated into heat energy, and part of it is released in the form of photons. Since the emitted photon energy is smaller than before, the wavelength is longer. Such white light-emitting diodes are less efficient because some of the energy is converted into heat during the conversion process, resulting in energy loss.
此外，雖目前發光二極體之技術不斷進步，但仍有不少缺點，發光二極體在高光度下效率較低，在一般照明用途上仍比 螢光燈 耗電，有些發光二極體燈甚至比省電燈泡耗電。有些設計使用多枚發光二極體，在保持整體光度下讓每枚發光二極體可以工作在較低光度，從而增加效率，但使成本大為提高，售價亦較其他類型燈泡較高，或是效率受高溫影響而急劇下降，浪費電力之餘也產生更多熱，令溫度進一步上升，形成惡性循環。除浪費電力也縮短壽命，因此需要良好散熱與演色性仍待加強。傳統燈泡、鹵素燈演色性極佳，而螢光燈管容易找到高演色性的產品；演色性低的光源照明不但會有顏色不正常的感覺，對視力及健康也有害 。In addition, although the technology of the light-emitting diode is continuously improved, there are still many shortcomings, the light-emitting diode is less efficient under high light, and still consumes more power than the fluorescent lamp in general lighting use, and some light-emitting diodes The lamp consumes even more power than the power-saving bulb. Some designs use multiple light-emitting diodes to allow each light-emitting diode to operate at lower luminosity while maintaining overall brightness, thereby increasing efficiency, but at a higher cost, and the price is higher than other types of light bulbs. Or the efficiency is drastically reduced by the influence of high temperature. When the power is wasted, more heat is generated, which causes the temperature to rise further and form a vicious circle. In addition to wasting power, life is shortened, so good heat dissipation and color rendering are still needed. Traditional light bulbs and halogen lamps have excellent color rendering properties, while fluorescent tubes are easy to find products with high color rendering. Light source lighting with low color rendering is not only abnormal in color, but also harmful to vision and health.
針對目前缺點有關於演色性待加強方面作技術研發應用，一般認為人造光源應讓人眼正確地感知色彩，就如同在太陽光下看東西一樣。所以越接近太陽光下所看到的物體的真實樣子就是演色性好，失真就是演色性不好。在某種光源照明下見到的各種色彩和用標準照明完全相同時，將此燈的平均演色評價指數（Ra）定為100。若平均演色評價指數Ra80以上，就基本上可以滿足色彩視度要求較高的照明要求，當然這需視應用之場合及目的而有不同之要求程度。此準據即是光源之演色特性，稱之為平均演色性指數(general color rendering index)。平均演色性指數為物件在某光源照射下顯示之顏色與其在參照光源照射下之顏色兩者之相對差異 。In view of the current shortcomings, there are technical developments and applications related to color rendering. It is generally believed that artificial light sources should make people's eyes correctly perceive color, just like watching things under the sun. Therefore, the closer the object is to the sun, the true appearance of the object is the color rendering, the distortion is the color rendering is not good. When the various colors seen under illumination of a certain light source are identical to those of standard illumination, the average color rendering index (Ra) of the lamp is set to 100. If the average color rendering index is above Ra80, it can basically meet the lighting requirements with higher color vision requirements. Of course, this needs to be different depending on the occasion and purpose of the application. This criterion is the color rendering property of the light source, called the general color rendering index. The average color rendering index is the relative difference between the color of an object displayed under illumination from a source and the color of the object under illumination.
經向上述目標努力後，發明人針對習知技術缺點作改良，使用具有混白光之發光二極體裝置，其於白光二極體模組內混合一琥珀光和一紅光，使該白光發光二極體模組所發出之白光與該琥珀光發光二極體晶片所發出之琥珀光與紅光發光二極體晶片所發出之紅光進行混光後照射，使該白光二極體模組具有較高演色性，此種光線照射下之物體於眼睛內會呈現該物體最近原本的顏色，是為一種具有新穎性與進步性之結構。After working towards the above objectives, the inventors have improved the shortcomings of the prior art, using a light-emitting diode device with mixed white light, which mixes amber light and a red light in the white light diode module to make the white light emit light.

With higher color rendering, the object under such light will present the original color of the object in the eye, which is a novel and progressive structure.

為使 貴審查委員對本發明之特徵及所達成之功效有更進一步之瞭解與認識，謹佐以較佳之實施例及配合詳細之說明，說明如後：In order to provide a better understanding and understanding of the features and the efficacies of the present invention, the preferred embodiment and the detailed description are as follows:
本發明改進習知發光二極體所發出之光線其較不具有較高的演色性之缺點，一般所指光源的演色性程度是指色彩顯現的真實度。做評價時，所代表的指數稱作平均演色性評價(Ra)，測量標準是以自然光Ra-100為100%真實色彩，是說明Ra數值越高之光線越能展現出其原本之色彩，通常晝光與白熾燈的演色指數定義為100，視為理想的基準光源。而這類演色性較高的燈具通常被利用於臨床檢查、畫廊與美術館等等地方，其為了看見最真實的色彩，但自從將傳統燈泡、鹵素燈等此類型燈泡應技術上應用換成發光二極體(LED)此種技術之照明後，並未兼顧此點演色性之優點，反而因為演色性低之光源照明造成會有顏色不正常的感覺，且對視力及健康也有害，故，本發明係為一種具有混白光之發光二極體裝置，其針對演色性之缺點作改進，比一般習知發光二極體更具有較高演色性，其主要技術特徵為於一白光內混合加入一紅光與一琥珀光，以產生出較高演色性之一混白光，當該混白光照色於一物體時，該物體於眼睛內會呈現出較真實之色彩。The invention improves the light emitted by the conventional light-emitting diode, which has the disadvantage of less high color rendering, and generally refers to the degree of color rendering of the light source refers to the trueness of the color appearance. In the evaluation, the index represented is called the average color rendering evaluation (Ra), and the measurement standard is that the natural light Ra-100 is 100% true color, which means that the higher the Ra value, the more the light can show its original color, usually The color rendering index for twilight and incandescent lamps is defined as 100, which is considered to be the ideal reference source. Such high-performance luminaires are often used in clinical examinations, galleries and art galleries, etc., in order to see the most realistic colors, but since the traditional light bulbs, halogen lamps, etc. should be technically applied to light After the illumination of the diode (LED) technology, the advantages of color rendering are not taken into account.

The invention is a light-emitting diode device with mixed white light, which is improved for the defects of color rendering, and has higher color rendering property than the conventional light-emitting diode. The main technical feature is that it is mixed in a white light. A red light and an amber light to produce a blend of white light with higher color rendering. When the white light is colored on an object, the object will have a more realistic color in the eye.
