Description
本發明是有關於一種光學裝置,且特別是有關於一種色彩測量裝置。 This invention relates to an optical device and, more particularly, to a color measuring device.
在現今的光學裝置中,基於低能耗和低損耗,固態光源(Solid-state light source)例如是發光二極體或是有機發光二極體已經大量被使用在我們生活四周。上述這些固態光源還具有體積小、產生熱能低的特性,因此固態光源也不斷在取代以往我們所使用的傳統光源例如是鎢絲燈、白熾燈、日光燈等等。 In today's optical devices, based on low energy consumption and low loss, solid-state light sources such as light-emitting diodes or organic light-emitting diodes have been widely used around our lives. These solid-state light sources also have the characteristics of small volume and low heat generation, so the solid-state light source is also constantly replacing the conventional light sources that we have used in the past, such as tungsten lamps, incandescent lamps, fluorescent lamps and the like.
然而,不同於傳統光源是藉由通電加熱來讓例如是燈絲發光,由於固態光源例如是發光二極體中的摻雜半導體在製作上並無法完全相同,而其中的誤差往往會使同時生產的多個發光二極體在發光時對人眼來說有顏色上的差異。上述顏色上的差異並無法藉由目前的相關色溫的定義來完全地辨別,導致分類為相同色溫的固態光源依然可能會具有肉眼能察覺的色彩差異。這樣的色彩差異有可能造成消費者無法藉由相關色溫的標示買到符合自己需求的光色之發光元件。 However, unlike conventional light sources, which are heated by energization to make, for example, filaments, the solid-state light sources, such as doped semiconductors in the light-emitting diodes, cannot be identical in fabrication, and the errors therein tend to result in simultaneous production. A plurality of light-emitting diodes have a color difference to the human eye when emitting light. The difference in color above cannot be completely discerned by the definition of the current correlated color temperature, so that solid-state light sources classified into the same color temperature may still have color differences that are perceptible to the naked eye. Such color differences may make it impossible for consumers to purchase light-emitting elements of light color that meet their needs by the indication of the relevant color temperature.
另外,藉由目前的光譜儀,雖然可以根據每個發光二極體或其他半導體光源所發出的光在例如是國際照明委員會(International Commission on Illumination,CIE)所創立的CIE 1931 xy色度空間(CIE 1931 xy chromaticity space)上的色度座標來作分類,但對於下游廠商或使用者而言,色度座標是一個比較陌生的參數。通常是對光學或色彩學較熟悉的使用者比較看得懂色度座標,其他使用者看了色度座標之後,往往仍然不知該如何運用所測得的參數。 In addition, with the current spectrometer, although the light emitted by each of the light-emitting diodes or other semiconductor light sources can be used, for example, the CIE 1931 xy chromaticity space (CIE) created by the International Commission on Illumination (CIE). The chromaticity coordinates on the 1931 xy chromaticity space) are classified, but for downstream manufacturers or users, the chromaticity coordinates are a relatively unfamiliar parameter. Usually, users who are more familiar with optics or color science can understand the chromaticity coordinates. After other users see the chromaticity coordinates, they still do not know how to use the measured parameters.
