摘要
为了研究不同黄疸治疗仪光源的发光光谱对新生儿产生紫外辐射、热辐射等潜在的光生物安全问题,本文利用光辐射安全测定系统OST-300对传统蓝光荧光灯、普通蓝光LED灯以及经简单遗传算法计算与拟合的蓝光LED灯进行了测试与对比分析。实验结果表明: 传统蓝光荧光灯在315,330,365 nm的紫外光处有明显的波峰出现,且峰值波长在365 nm处较为明显; 传统蓝光荧光灯在老化后其蓝光光谱光衰严重,且存在大量的红外光线; 而基于简单遗传算法计算与拟合的蓝光LED发光光谱与体内胆红素的吸收光谱相吻合,能避免对新生儿的光辐射危害。因此,本文提出的蓝光LED是治疗新生儿黄疸的理想光源。
Abstract
In order to research the ultraviolet radiation, thermal radiation and other potential photobiological safety problems in different luminescence spectra of jaundice therapeutic devices, the spectrum of the traditional blue fluorescent lamp, the common blue LED lamp, the blue LED lamp through calculation and fitting by the simple genetic algorithm are tested and compared using the optical radiation safety test system OST-300. Experimental results indicate that, there are three obvious peaks at 315, 330 and 365 nm for the traditional blue fluorescent lamp, and the peak is more obvious at 365 nm; the blue spectrum attenuation of the traditional blue fluorescent lamp after aging is serious, existing a lot of infrared light. The spectrum of the blue light LED based on calculation and fitting by the simple genetic algorithm conforms to the absorption spectrum of bilirubin in vivo. The blue light LED can avoid the optical radiation damage to the neonate, and it is an ideal light source for the neonatal jaundice treatment.
