人力驱动的超级电容多源充放电集成型LED台灯

在原理可行性评估基础上,设计并实现了一种基于超级电容多源充电、LED照明及对电子数码产品等多档位充电相结合的人工驱动集成型LED台灯系统。该系统采用超级电容为供电电源,以手摇发电机、脚踏式发电机及多种形式发电机为充电电源,充电时可根据阻力程度选择4个不同档位,存储下来的电能可供LED照明或者应用多档位DC-DC转接口对各种电子数码产品以及不同类型的蓄电池、充电电池进行充电。测试结果表明,此照明系统使用功率为12 W的手摇发电机为13.5 V/96 F的超级电容模组(1档)充电需时3.5 min,其放电可使4 W LED节能灯连续正常工作5.8 min;4档全部充满最多可支持LED节能灯正常工作21.7 min。本系统可规模化普及并配置于家庭、办公场所及户外环境作为新型绿色能源电器使用。

Human-powered integrated LED lighting system using super capacitor for multi-source electricity recharging

Based on feasibility evaluation,a human-powered integrated lamp system combining super multi-source capacitor and LED together was designed and fabricated.The system worked by using hand or foot driven generator and other generators to charge super capacitance for storing electricity.According to different degrees of electric resistance,four levels of engine states were designed for option.The storage of electric energy could be used to charge LED,various digital products,accumulators and rechargeable batteries by using multi grade DC-DC transfer connector.According to the measurements,the charging process for the super capacitance series(13.5 V/96 F,1st level of engine state) took about 3.5 minutes with the hand dynamo,whose rated power was 12 W.The super capacitor series thus recharged could keep driving the energy-saving LED lamp(24 V,4 W) to continuously work for 5.8 minutes.When the super capacitance series(all the engine states) were fully charged,and the LED lamp could work for 21.7 minutes at the most.The present system could be used in large-scale or served as new green-energy electrical appliances in the home,office and outdoor environment.
