技術說明

本發明係提出一種對人體友善的光源及其用途，其中所述對人體友善的光源係包括: 至少一發光單元以及複數片彼此相互堆疊的色溫調降膜；其中，該些色溫調降膜係連接至該發光單元的一發光面，用以對該發光單元所發出的一色光進行一色溫調降處理。並且，完成所述色溫調降處理的該色光係變成一橘白光。實驗數據證實，兩片以上的色溫調降膜對於色光的色溫與亮度之調降有明顯的加強效果。除此之外，隨著該色溫調降膜的堆疊數量之增加，視網膜對於該橘白光最大可忍受曝照極限之時間也跟著遞增。同時，隨著該色溫調降膜的堆疊數量之增加，該橘白光對於褪黑激素的抑制敏感度係遞減。 The present invention discloses a human body-friendly light source and use thereof, wherein the human body-friendly light source comprises: at least one lighting unit and a plurality of color temperature (CT) reducing films stacked to each other. The CT reducing films are connected to a light emission surface of the lighting unit, so as to apply a color temperature reducing treatment to a light emitted by the lighting unit. Exponential data have proved that, two stacked CT reducing films exhibit an apparent color temperature reducing effect on the lighting unit. Exponential data also proved that, with the increasing of the stack numbers of the CT reducing films, the light is eventually concerted to an orange-white light, time of maximum permissible retina exposure limit (MLP) is enhanced, and melatonin suppression in response to light is reduced.
