摘要：
Disclosed herein is a light fixture. The light fixture includes at least one first light source that emits at a peak wavelength in a range of approximately 380nm to approximately 420nm and at least one second light source that emits at a different peak wavelength, wherein a combined light output of the at least one first light source and the at least one second light source emits a colored light that is perceived as white light. The white light is defined by having a color rendering index (CRI) value of more than approximately 50. The at least one second light source that emits at a different peak wavelength consists of an xy coordinate on a International Commission on Illumination (CIE) 1931 xy color space diagram above a black body curve within a bounded area defined by a first line of approximately y = 2.23989x - 0.382773 and a second line of approximately y = 1.1551x - 0.195082. The combined light output has a proportion of spectral energy measured in the approximately 380nm to approximately 420nm range of greater than approximately 20%.本發明揭示一種燈具。該燈具包含依在約380nm至約420nm之範圍中之峰值波長發射之至少一第一光源及依不同峰值波長發射之至少一第二光源，其中至少一第一光源及至少一第二光源之組合光輸出發射經感知為白光之彩色光。該白光由具有多於約50之演色指數(CRI)值予以定義。依一不同峰值波長發射之該至少一第二光源由約y=2.23989x-0.382773之第一線及約y=1.1551x-0.195082之第二線定義之經定界區域內之黑體曲線上方之國際照明委員會(CIE)1931 xy色彩空間圖上之xy座標組成。該組合光輸出具有大於約20%之在約380nm至約420nm之範圍中經量測之光譜能量之比例。
