健康照明光谱配方与LED器件研究

光除了提供光亮,刺激视觉形成外,还会对人的生理、心理等方面产生显著影响,促使功能照明向健康照明发展。本文结合光在视觉和非视觉两个方面的研究进展,分析短波蓝光的危害及长波蓝光的生物效应,在太阳光光谱的基础上对蓝光波段进行能量分布修正,设计出健康的光谱能量分布曲线,进而开发出健康照明用类太阳光LED器件。

Study on Healthy Lighting Spectra and LED devices

Light can not only provide brightness by visual function but exert huge influence on people’s physiology and psychology through non-visual effect, which brings the attention to healthy lighting. This paper reviews the development of light of visual and non-visual effects on human health and summaries the roles of blue light in vision health and biological rhythm. According to the risk of short-wavelength blue light and the biological effect of the long-wavelength one, we come up with spectral power distribution for healthy lighting by adjusting the blue light of solar spectrum. Finally, the sun-like LED device for healthy lighting was then developed.
