| 摘 要： | 提出一种基于发光二极管(LED)开发的便携式光强可调黄疸光疗仪。仪器选用蓝色LED实现特殊阵列排布,并基于芯片MAX5035构建恒流驱动电路,驱动电流受单片机ATmega16L程序控制,可实现对仪器光照强度的线性调节,并将其对应光强值显示在液晶12864。与传统黄疸光疗仪相比,仪器体积小,光照强度强,并能实现一定范围光强调节。

| Abstract: | Our group have introduced a portable light emitting diode (LED) phototherapy system for treating neonatal jaundice. The device selects blue narrow-band LED as the light source, driven by MAX5035. The light intensity is linearly adjusted as the alteration of the pulse-width modulation signal, controlled by ATmega16L, and the value can be displayed in LCD12864. The device breaks the bonds of traditional phototherapy, it features small size and can provide an intense irradiance-controlled treatment as it's needed. |
