摘要:本设计实现了绿色、高效、节能、方便的目的。设计分五步:太阳能发电存储模块、光控模块、声控模块、门电路模块、延时电路模块。设计用到的理论有数电模电知识、光敏电阻伏安特性、三极管、逻辑门电路、太阳能硅光发电等,实现了集太阳能发电与声光控小夜灯于一体,灯具改用新型光源LED,既能实现只有在夜间有声时灯光才能发光,又能实现自给供电的目的,并且可以发挥突然断电应急灯的功效。太阳光为能源,绿色健康。白天利用利用太阳能对蓄电池充电晚上蓄电池放电,自给供能;声光控延时,能源高效利用;光源LED绿色节能,工作电压低、亮度大、寿命长、安全稳定可靠。40629 毕业论文关键词:太阳能;声控灯;光敏电阻;麦克风;与非门
Sound and light-controlled night light design
Abstract: This design achieve the purpose of the green, high efficiency, energy saving, convenient. design step five: solar power storage module, optical module, voice control module, a gate circuit module, a delay circuit module. Design used the theory of several electrical electrical knowledge, photosensitive resistance volt-ampere characteristic, triode, logic gate, solar silicon optical power, etc. has realized the collection of solar power and acoustic electric small night light into an organic whole, to switch to the new light source LED lamps and lanterns, can not only realize the only sound in the night when the light to shine and to achieve the purpose of self power supply, and can play to suddenly loses power emergency light effect. Sunlight for energy, green health. Using the use of solar energy during the day for battery charging battery discharge in the evening, self-sufficient power; Optical delay, energy efficient utilization; Green light LED and energy saving, low work voltage, large brightness, long life, safe and reliable.
Keywords: Solar energy; Voice-activated Lights; Light-sensitive resistors; Microphone; NAND gate
