高光譜圖像資訊是研究LED的強大工具，優勢在於精細的光譜分辨率、空間資訊、非破壞性。高光譜圖像能捕捉LED發射光譜的微小變化，並同時在整個LED表面進行空間映射，從而實現對性能變化和缺陷的識別，其豐富的光譜信息可協助研究分析，可以應用於LED產生的熱效應時的藍光洩漏檢測。實驗室自製高光譜儀由光源經物鏡系統聚焦，光柵分光後至成像系統，且儀器配合移動平台以線掃描的方式，紀錄 LEDs 樣品連續光譜帶範圍在 380nm-685nm 的高光譜圖，在經過校正：包含使用光纖光譜儀量測單色光 LED 、冷白LED樣品後定義實驗室高光譜儀的波長像素圖，以及取出光強度參數值，透過 CIE1931 的色匹配函數還原出像素RGB組合成一張套色圖，將一維光譜數據以及二維空間數據組成三維的高光譜立方數據，利用儀器的高解析度光譜資訊，分析不同功率藍光 LED 激發螢光粉後於感興趣區域的光譜特徵，研究結果表明了主要發光區域中心與邊帶的散射和轉換效率之差異，其中將LEDs的套色圖立體化，使其更具有清楚檢視效果。.

520 3 $a Hyperspectral imaging is a powerful tool for studying LEDs, offering advantages in spectral resolution, spatial information, and non-destructiveness. It captures subtle variations in LED emission spectra and simultaneously maps the entire LED surface spatially, enabling the identification of performance variations and defects. Its rich spectral information aids in research analysis and can be applied to detect blue light leakage during thermal effects in LED production. A home-built hyperspectral imager in the laboratory utilizes a light source, a lens system for focusing, and grating spectroscopy, followed by an imaging system. Integrated with a movable platform, it records the continuous spectrum of LED samples within the range of 380nm–685nm through line scanning. After calibration, involving measurements of monochromatic and white LEDs using a fiber optic spectrometer, the wavelength-pixel map of the laboratory hyperspectral imager is defined, and intensity parameter values are extracted. Employing the CIE1931 color matching function, a pseudo-color image is reconstructed from pixel RGB combinations. One-dimensional spectral data and two-dimensional spatial data are then assembled into three-dimensional hyperspectral cube data. Utilizing the high-resolution spectral information provided by the instrument, the analysis focuses on the spectral characteristics of phosphors excited by different power blue LEDs in the region of interest. The research reveals differences in the scattering and conversion efficiencies between the central and edge bands of the main emission region. Additionally, the pseudo-color image of LEDs is rendered three-dimensionally for clear visualization..
