摘要
利用MK6A11P的微功耗特性,设计了具有微功耗、声光控制、高灵敏度的LED照明灯。其具有<0.1 W的待机功耗、灵敏度高,克服了现有声控灯灵敏度过低的问题。同时解决了声控灵敏度高时产生的常亮现象,可广泛应用于人群流动较为随机的公共场所,如走廊、电梯口、公共卫生间等。经实验证明,这种LED照明灯具有电路简单、工作稳定可靠、点亮时间可调等优点。
On the basis of MK6A11P＇s characteristic of micro-power consumption, this paper designs an LED lamp with the characteristics of micro-power consumption, sound and light control and high sensitivity. It has a standby power consumption of less than 0. 1 W and high sensitivity, thus overcoming the problem of the existing a- coustic-control lamp of low sensitivity and also dealing with the problem that the lamp is always lighting when the sen- sitivity of acoustic control is high. The LED lamp can be widely used in public areas where the flow of people chan- ges at random such as corridors, elevator entrance and public toilet. Experiments show that the LED lamp has the advantages of simple circuit structure, high operation stability and adjustable lighting time.
