技术领域 FIELD

[0001] 本发明涉及一种照明装置,且特别涉及一种具有可变色温的照明装置。 [0001] The present invention relates to a lighting apparatus, and more particularly relates to a lighting apparatus with variable color temperature. 背景技术 Background technique

[0002] 随着科技的进步,使用者对于照明的需求日益增加,对照明品质的要求也逐渐提高。 [0002] As technology advances, users growing demand for lighting, lighting quality requirements also gradually improve. 近年来,发光二极管(LED)已渐渐取代传统的光源,主要是由于发光二极管与传统光源相较之下,具有发光效率佳、寿命长、可靠度高以及体积小等优点,故其应用的范围非常广泛。 In recent years, a light emitting diode (LED) have gradually replaced conventional light sources, mainly due to comparison with the conventional light-emitting diode below the light source having a good luminous efficiency, long life, high reliability and small size, etc., so the scope of its application very extensive.

[0036]下列将以实施例来说明上述由CIE色度图中相应座标点的线性关系来决定具有第三波长的光颜色的方式。 [0036] The following examples will illustrate the above-described respective coordinate point in the CIE chromaticity diagram to determine the linear relationship of color light having a third wavelength manner. 图2为依照本发明实施例绘示一种CIE色度图及其中色度座标点匹配的情形。 FIG 2 is a chromaticity diagram and illustrates a situation in CIE chromaticity coordinates of point matching schematic embodiment according to the present embodiment of the invention. 同时参照图1和图2,具有第一波长的光(如蓝光)在色度图中位于座标点B,具有第二波长的光(如红光)在色度图中位于座标点R,具有第一色温的白光以及具有第二色温的白光在色度图中分别位于座标点W1、W2,且座标点W1、W2大致位于黑体曲线200上。 Referring to FIGS. 1 and 2, light having a first wavelength (e.g., blue) coordinates of the point B is located in the chromaticity diagram, a second wavelength of light (e.g., red light) having a coordinate point R is located in the chromaticity diagram, having white white light having a first color temperature and a second color temperature are located at the coordinate point in the chromaticity diagram W1, W2, and a coordinate point W1, W2 located substantially on the black body curve 200. 其次, 座标点B和座标点W1经匹配而形成第一延伸线L1,座标点R和座标点W2经匹配而形成第二延伸线L2,而具有第三波长的光(如包含蓝光波长的特定荧光)在色度图中则大致位于第一延伸线L1与第二延伸线L2的相交处(即座标点P)。 Secondly, the coordinate point B and the coordinates of the matched points W1 to form a first extension lines L1, coordinates of points R and matching the coordinate point W2 is formed by the second extension line L2, and the light having a third wavelength (e.g., blue light containing a specific wavelength fluorescence) in the chromaticity diagram extending substantially located at the first line L1 and the second line L2 extending in the intersection (i.e., coordinate point P). 因此,第三发光元件130所发出具有第三波长的光(位于座标点P),便可与第一发光元件110所发出具有第一波长的光(位于座标点B) 和第二发光元件120所发出具有第二波长的光(位于座标点R)选择性地混合形成黑体曲线200上的白光。 Thus, the third light emitting element 130 emits light having a third wavelength (the point P at coordinates), can be the first light emitting element (point at coordinates B) having a first wavelength and a second light emitting element 120 emits 110 light having a second wavelength (at the coordinate point R) emitted from the white light are selectively formed by mixing 200 on the black body curve. 如此一来,便可有效地让形成的白光确切地落于黑体曲线200上,避免所形成白光的颜色有明显偏差的情形发生,而且混光的操作可以较有弹性地来进行,使混光形成的白光颜色相对均勾。 Thus, white light can be efficiently formed so exactly fall on the black body curve 200, color white to avoid the situation of occurrence of significant deviations form, and light mixing operation may be carried out more flexible, so that the light mixing white color are formed opposite the hook. [〇〇37] 在一实施例中,具有第三波长的光(位于座标点P)可与具有第一波长的光(位于座标点B)混合而形成具有第一色温的白光(位于座标点W1),而具有第三波长的光(位于座标点P)可与具有第二波长的光(位于座标点R)混合而形成具有第二色温的白光(位于座标点W2) 〇[〇〇38] 此外,上述具有第三波长的光(位于座标点P)在CIE色度图中的座标点不位于黑体曲线200上。 [〇〇37] In one embodiment, the third wavelength light (the point at coordinates P) may be formed having a first coordinate point having a color temperature of white light (the light of the first wavelength positioned (located at the coordinate point B) are mixed with W1), and the light having a third wavelength (the point at coordinates P) with light having a second wavelength (at the coordinate point R) to form a white light having a second mixed color temperature (the point at coordinates W2) billion [〇〇38 ] Further, the light (the point at coordinates P) having a third wavelength coordinate point in the CIE chromaticity diagram is not located on the black body curve 200. 如此一来,便可通过调整并混合具有第一波长的光、具有第二波长的光和具有第三波长的光,来形成色度图中大致位于黑体曲线上的白光。 In this way, and can be adjusted by mixing the light having a first wavelength, light having a third wavelength light having a second wavelength, to form a white light chromaticity diagram is located substantially on the black body curve. [〇〇39] 在另一实施例中,具有第一色温的白光(位于座标点W1)可以是一色温范围内具有最高色温(如5000K)的冷白光,具有第二色温的白光(位于座标点W2)可以是色温范围内具有最低色温(如2700K)的暖白光。 [〇〇39] In another embodiment, the white light having a first color temperature (the point at coordinates W1) may be a cold white light with the highest color temperature (e.g., 5000K) in a range of color temperature of white light having a second color temperature (on the seat punctuation W2) may be a white light having a warm color temperature of the lowest (e.g., 2700K) within the color temperature range. 另外,具有第三波长的光(位于座标点P)可与具有第一波长的光或是蓝光混合而形成具有最高色温的冷白光,具有第三波长的光(位于座标点P)可与具有第二波长的光或是红光混合而形成具有最低色温的暖白光。 Further, the third wavelength light (the point at coordinates P) or can be mixed with blue light having a first wavelength to form a cool white color temperature has the highest light having a third wavelength (the point at coordinates P) having having or red wavelength light to form a second mixture warm white color temperature has the lowest.
