目的：为合理解释非视觉感光系统响应量与光照之间的关系，探讨 LED 照度光环境对学习者学习效率及疲劳度的影响。方法首先利用等效类比的方法建立了基于 MOSFET 电路的非视觉感光系统模型，然后利用 Multisim 12.0软件进行了 MOSFET 电路仿真，并验证了非视觉感光系统与MOSFET电路模型一致性。最后结合新型学习工具———平板显示器，通过改变光环境照度，采用安菲莫夫字母表测试了6名学习者的学习效率与疲劳度。结果结果显示，学习效率随着照度增加而增加，照度在700 lx附近达到最大，视疲劳与脑疲劳较小。结论利用本文所建立的基于 MOSFET电路的非视觉感光系统模型，较好地解释了光感受系统作用机制，并综合考虑学习效率、视疲劳和脑疲劳三方面因素，提出合理照明建议：在多数学习任务情境下，应尽可能选择700 lx附近 LED光源作为光环境照度。

Objective To explaln the relationship between lighting and response of non-visual photo sensitive system and to discuss the impact of LED illumination of light environment on learning efficiency and fatigue of learners. Methods Firstly this paper proposes a model which based on the MOSFET circuit for non-visual photo sensitive system using the analog equivalent method and is simulated with Multisim 12. 0 software. There is a consistence between MOSFET circuit model and non-visual photo sensitive system. Finally, Combined with the new learning tools,flat panel display,we study on the impact of LED illumination of light environment on learning efficiency and the fatigue of six learners with Anfimov alphabet. Results The results show that learning efficiency is growing with the increase of lighting illumination. Maximum learning efficiency is in the 700Lx lighting with small visual fatigue and braln fatigue. Conclusions By using this model,the mechanism of its action can be explalned well. Considering the visual fatigue,braln fatigue and learning efficiency, we propose reasonable lighting suggestion:under most learning task situation,the nearly LED 700Lx light source should be chosen as far as possible.
