【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。更多还原

【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.更多还原
