摘　要：LED技术的发展和普及极大地满足了人们对视觉效果的追求，但是伴随而来的大量光辐射也引发了人们对于光生物安全问题的担忧。目前已知的白光LED制作方式，绝大多数都是使用蓝色LED芯片来激发黄色荧光粉，最终混合制成白光，导致其中含有大量的蓝光成分。蓝光辐射危害是目前人类受到的最主要的光辐射危害之一。本文通过对蓝光危害的产生原理、危害评价机制以及对人类的影响进行综述，旨在揭示蓝光危害的严重性，为防范蓝光危害提供理论依据和实践指导。

Abstract: The development and popularization of LED technology has greatly satisfied people’s pursuit of visual effects, but the attendant large amount of light radiation has also caused people’s concern about the safety of light biology. At present, most of the known white LED production methods are using blue LED chips to stimulate yellow phosphors, and finally mixed into white light, resulting in rich blue components. At present, the harm of blue light radiation is one of the most important light radiation hazards to human beings. In this paper, the principle of blue light hazard, hazard evaluation mechanism, and the impact of blue light hazard on human beings are reviewed to reveal the severity of blue light hazard and provide theoretical basis and practical guidance for preventing blue light hazard.
Key words: blue light hazard; blue light measurement; photobiosafety; light radiation hazard; LED technology
