Description
本發明是有關於一種光特性可調之照明裝置，且特別是有關於一種可調變照明光線的亮度、色溫與演色性的照明裝置。The invention relates to a lighting device with adjustable light characteristics, and in particular to a lighting device capable of adjusting the brightness, color temperature and color rendering of illumination light.
人眼在觀察自然光或人造光源照明下的物體時，必須具有足夠的亮度才能呈現出色彩。當照明光線消失時，色彩也隨之消失。光和色彩一樣，對人會造成冷暖之感受，亦即光的色溫之概念。光源的色溫不同，光色也不同。利用調整光源的色溫可形成適宜的環境氣氛，如使用低色溫光源能得到溫暖、柔和的氣氛；採用高色溫光源能得到清冷、寧靜的氣氛。When the human eye observes an object illuminated by natural light or an artificial light source, it must have sufficient brightness to present color. When the lighting light disappears, the color disappears. Light and color, the feeling of warmth and warmth to people, that is, the concept of the color temperature of light. The color temperature of the light source is different and the light color is different. By adjusting the color temperature of the light source, a suitable ambient atmosphere can be formed. For example, a low color temperature light source can be used to obtain a warm and soft atmosphere; a high color temperature light source can be used to obtain a cool and quiet atmosphere.
色溫的定義以絕對溫度K來表示，亦即將標準黑體加熱，溫度升高到一定程度時，光源的顏色開始由深紅、淺紅、橙黃、白、藍而逐漸改變。當光源與黑體的顏色相同時，黑體當時的絕對溫度稱為該光源之色溫。一般而言，色溫在3,000 K呈暖色光，使人感覺輕鬆與舒適，適合使用於住宅或旅館。色溫在4,000到5,000K，呈柔和白色光，適合使用於辦公室或學校。色溫在6,000K，呈較冷色調的晝光色，適合使用於印刷、紡織、染整等工業廠商。The definition of color temperature is expressed by the absolute temperature K, that is, the standard black body is heated, and when the temperature is raised to a certain extent, the color of the light source begins to change gradually from deep red, light red, orange yellow, white, and blue. When the color of the light source is the same as that of the black body, the absolute temperature of the black body at that time is called the color temperature of the light source. In general, the color temperature is warm at 3,000 K, making it feel relaxed and comfortable, suitable for use in a home or hotel. With a color temperature of 4,000 to 5,000K, it is soft white and suitable for use in offices or schools. The color temperature is 6,000K, which is a cool color shade, suitable for printing, textile, dyeing and other industrial manufacturers.
然而，傳統的照明用具僅考慮光源的色溫調整。在照明用具的光源的照明品質升高的發展趨勢之下，勢必要進一步考慮照明用具的光源的其他光學因子，如演色性、光通量等等，而這是目前的照明用具難以突破的技術瓶頸。However, conventional lighting fixtures only consider the color temperature adjustment of the light source.

In other words, the light characteristic adjustable illumination device 100 simultaneously considers the color rendering properties, the color temperature, and the intensity of the luminous flux of the first to fourth light rays L1 to L4.
在一實施例中，激發光線EL的中心波長可為450 nm～470 nm，亦即，激發光線EL可為藍光波段。換言之，亮度可調光源110可為藍光發光二極體晶片，提供一藍光用以激發第一～第四螢光粉組合122A～128A。In an embodiment, the center wavelength of the excitation light EL may be 450 nm to 470 nm, that is, the excitation light EL may be a blue light band. In other words, the brightness tunable light source 110 can be a blue light emitting diode chip, and a blue light is provided to excite the first to fourth phosphor powder combinations 122A-128A.
請繼續參照圖1，第一螢光粉組合122A可包括：紅色螢光粉R以及黃色螢光粉Y，其中，紅色螢光粉R與黃色螢光粉Y的比值範圍為大於或等於0.35且小於0.6之間。藉由激發光線EL(如藍光)來激發黃色螢光粉Y放射出黃光，且激發紅色螢光粉R放射出紅光，使得藍光、黃光與紅光一起混光成白光(第一光線L1)。利用紅色螢光粉R與黃色螢光粉Y的組成比例來調整混光後的第一光線L1的演色性與色溫，而得到：低演色性與低色溫(溫暖感受)的白光(第一光線L1)。Referring to FIG. 1 , the first phosphor powder combination 122A may include: red phosphor powder R and yellow phosphor powder Y, wherein the ratio of the red phosphor powder R to the yellow phosphor powder Y is greater than or equal to 0.35 and Less than 0.6. The yellow fluorescent powder Y emits yellow light by exciting the light EL (such as blue light), and the red fluorescent powder R emits red light, so that the blue light, the yellow light and the red light are mixed together to form white light (first light) L1). The color ratio and color temperature of the first light L1 after the light mixing are adjusted by using the composition ratio of the red fluorescent powder R and the yellow fluorescent powder Y, thereby obtaining white light with low color rendering and low color temperature (warm feeling) (first light) L1).
再者，第二螢光粉組合124A可包括：紅色螢光粉R以及黃色螢光粉Y，其中，紅色螢光粉R與黃色螢光粉Y的比值範圍為大於或等於0.1且小於0.35之間。藉由激發光線EL(如藍光)來激發黃色螢光粉Y放射出黃光，且激發紅色螢光粉R放射出紅光，使得藍光、黃光與紅光一起混光成白光(第二光線L2)。利用紅色螢光粉R與黃色螢光粉Y的組成比例來調整混光後的第二光線L2的演色性與色溫，而得到：高演色性與高色溫(清冷感受)的白光(第二光線L2)。Furthermore, the second phosphor powder combination 124A may include: red phosphor powder R and yellow phosphor powder Y, wherein the ratio of the red phosphor powder R to the yellow phosphor powder Y is greater than or equal to 0.1 and less than 0.35. between. The yellow phosphor powder Y emits yellow light by exciting the light EL (such as blue light), and the red phosphor powder R emits red light, so that the blue light, the yellow light and the red light are mixed together to form white light (second light) L2). The color ratio and color temperature of the second light L2 after the light mixing are adjusted by using the composition ratio of the red fluorescent powder R and the yellow fluorescent powder Y, thereby obtaining white light with high color rendering and high color temperature (cool feeling) (second light) L2).
第三螢光粉組合126A可包括：紅色螢光粉R以及黃色螢光粉Y，其中，紅色螢光粉R與黃色螢光粉Y的比值範圍為大於或等於0.6且小於或等於0.85之間。藉由激發光線EL(如藍光)來激發黃色螢光粉Y放射出黃光，且激發紅色螢光粉R放射出紅光，使得藍光、黃光與紅光一起混光成白光(第三光線L3)。利用紅色螢光粉R與黃色螢光粉Y的組成比例來調整混光後的第三光線L3的演色性與色溫，而得到：高演色性與低色溫(溫暖感受)的白光(第三光線L3)。The third phosphor powder combination 126A may include: a red phosphor powder R and a yellow phosphor powder Y, wherein a ratio of the red phosphor powder R to the yellow phosphor powder Y ranges from greater than or equal to 0.6 and less than or equal to 0.85. . The yellow fluorescent powder Y emits yellow light by exciting the light EL (such as blue light), and the red fluorescent powder R emits red light, so that the blue light, the yellow light and the red light are mixed together to form white light (the third light) L3). The color ratio and color temperature of the third light L3 after the light mixing are adjusted by using the composition ratio of the red fluorescent powder R and the yellow fluorescent powder Y, thereby obtaining white light with high color rendering and low color temperature (warm feeling) (third light) L3).
第四螢光粉組合128A可為黃色螢光粉Y或是進一步包含少量的紅色螢光粉R，其中，紅色螢光粉R與黃色螢光粉Y的比值範圍為大於或等於0且小於0.1之間。藉由激發光線EL(如藍光)來激發黃色螢光粉Y放射出黃光，且使得藍光、黃光一起混光成白光(第四光線L4)。由於第四光線L4不具有紅光成分，所以混光後的第四光線L4的演色性與色溫成為：低演色性與高色溫(清冷感受)的白光(第四光線L4)。The fourth phosphor powder combination 128A may be yellow phosphor powder Y or further contain a small amount of red phosphor powder R, wherein the ratio of the red phosphor powder R to the yellow phosphor powder Y is greater than or equal to 0 and less than 0.1. between. The yellow phosphor powder Y is excited to emit yellow light by exciting the light EL (such as blue light), and the blue light and the yellow light are mixed together to form white light (fourth light beam L4). Since the fourth light ray L4 does not have a red light component, the color rendering property and the color temperature of the fourth light ray L4 after the light mixing are white light (fourth light ray L4) having low color rendering property and high color temperature (cool feeling).
演色性指數可以量化，用以決定第一光線L1～L4之中，何者為高演色性或低演色性。在一實施例中，上述的第一演色性指數小於80，第二演色性指數大於或等於80。換言之，小於80的演色性指數可視為具有低演色性，高於或等於80的演色性指數可視為具有高演色性。The color rendering index can be quantified to determine which of the first rays L1 to L4 is high color rendering or low color rendering. In one embodiment, the first color rendering index is less than 80 and the second color rendering index is greater than or equal to 80. In other words, a color rendering index of less than 80 can be regarded as having a low color rendering property, and a color rendering index higher than or equal to 80 can be regarded as having a high color rendering property.
同樣地，色溫也可以量化，用以決定第一光線L1～L4之中，何者為高色溫或低色溫。在一實施例中，上述的第一色溫為2,500 K至4,000K，第二色溫為4,500K至6,500 K。換言之，2,500 K至4,000K的色溫可視為具有低色溫，4,500K至6,500 K的色溫可視為具有高色溫。Similarly, the color temperature can also be quantified to determine which of the first rays L1 to L4 is a high color temperature or a low color temperature. In one embodiment, the first color temperature is from 2,500 K to 4,000 K and the second color temperature is from 4,500 K to 6,500 K. In other words, a color temperature of 2,500 K to 4,000 K can be regarded as having a low color temperature, and a color temperature of 4,500 K to 6,500 K can be regarded as having a high color temperature.
承上述，光特性可調照明裝置100同時考慮了第一～第四光線L1～L4的演色性、色溫以及光通量的強弱，不單單考慮色溫，進而能夠提供更好的照明品質。In view of the above, the light characteristic adjustable illumination device 100 simultaneously considers the color rendering properties, color temperature, and luminous flux of the first to fourth light rays L1 to L4, and not only considers the color temperature, but also provides better illumination quality.
值得注意的是，在圖1的光特性可調之照明裝置100中，透明基板120為可轉動的圓形透明基板，藉由轉動圓形透明基板，而使激發光線EL在第一至第四區域122~128中進行切換，以選擇第一至第四光線L1~L4其中之一。如此，可以更方便地選擇所需的演色性、色溫的光線。It should be noted that in the illuminating device 100 with adjustable light characteristics of FIG. 1, the transparent substrate 120 is a rotatable circular transparent substrate, and the excitation light EL is first to fourth by rotating the circular transparent substrate. The areas 122 to 128 are switched to select one of the first to fourth light rays L1 to L4. In this way, it is more convenient to select the desired color rendering and color temperature light.
圖2為本發明較佳實施例的又一種光特性可調之照明裝置的示意圖。請參照圖2，相同的元件標示以相同的符號，並省略相同的說明。值得注意的是，在圖2的光特性可調照明裝置102中，透明基板120可在一設定方向D往返移動，而使激發光線EL在第一至第四區域122~128中進行切換，以選擇第一至該第四光線L1~L4其中之一。如此，也可方便地選擇所需的演色性、色溫的光線。2 is a schematic view of still another illumination device with adjustable light characteristics according to a preferred embodiment of the present invention. 2, the same components are designated by the same reference numerals, and the same description is omitted. It should be noted that in the light characteristic adjustable illumination device 102 of FIG. 2, the transparent substrate 120 can reciprocate in a set direction D, and the excitation light EL is switched in the first to fourth regions 122-128 to One of the first to the fourth rays L1 to L4 is selected. In this way, it is also convenient to select the desired color rendering and color temperature light.
圖3為本發明較佳實施例的再一種光特性可調之照明裝置的示意圖。請參照圖3，相同的元件標示以相同的符號，並省略相同的說明。值得注意的是，在圖3的光特性可調照明裝置104中，上述的亮度可調光源110可包括：多個藍光發光二極體單元112，當激發光線EL照射具有第二演色性指數的第二區域124與第三區域126時，或是當激發光線EL照射具有第一色溫的第一區域122與第三區域126時，增加點亮藍光發光二極體單元112的數量，而提昇激發光線EL的亮度。FIG. 3 is a schematic diagram of still another illumination device with adjustable light characteristics according to a preferred embodiment of the present invention. 3, the same components are designated by the same reference numerals, and the same description is omitted. It should be noted that, in the light characteristic adjustable illumination device 104 of FIG. 3, the brightness tunable light source 110 may include: a plurality of blue light emitting diode units 112, when the excitation light EL is illuminated with a second color rendering index When the second region 124 and the third region 126 are irradiated, or when the excitation light EL illuminates the first region 122 and the third region 126 having the first color temperature, the number of the blue light emitting diode units 112 is increased, and the excitation is increased. The brightness of the light EL.
這是因為，高演色性或是低色溫之區域具有的紅色螢光粉組合會吸收較大量的激發光線EL，導致激發光線EL 本身的光通量過度減弱。藉由上述亮度可調光源110的設計方式，可以補償過度減弱的激發光線EL，使得經過高演色性或低色溫之區域的第一光線L1、第二光線L2與第三光線L3可具有所需之亮度。This is because the red phosphor powder combination in the region of high color rendering or low color temperature absorbs a large amount of excitation light EL, resulting in excitation light EL. The luminous flux itself is excessively weakened. By the design of the brightness-adjustable light source 110 described above, the excessively weakened excitation light EL can be compensated for, so that the first light L1, the second light L2 and the third light L3 in the region of high color rendering or low color temperature can have the desired Brightness.
綜上所述，本發明的光特性可調照明裝置至少具有以下優點：光特性可調之照明裝置具有：亮度可調光源、與設置有不同螢光粉組合的透明基板。藉由亮度可調光源所放射的激發光線來激發不同的螢光粉組合，而能夠選擇不同的演色性與色溫的光線。同時，利用亮度可調光源來調整光線的光通量，以使光線具有適當的亮度。上述光特性可調照明裝置能夠同時整合演色性、色溫以及光強度，而得到所需的演色性、色溫以及光強度的光線，以滿足更高標準的照明需求。In summary, the light characteristic adjustable illumination device of the present invention has at least the following advantages: the illumination device with adjustable light characteristics has a brightness adjustable light source and a transparent substrate provided with a combination of different phosphor powders.
