The Design Of LED Intelligent Lighting System

The lighting is a kind of important need in our daily life.Illuminate the proportion had in the middle of canning consume to increase day by day on the other hand, in the energy day by day nervous today, how raise its energy utilization is an important topic that puts in people’s in front; On the other hand, along with the request of social development people to the life quality more and more high, turn to the intelligence of lighting, the automation need is outstanding.The intelligence control is to solve these two problem of the best way.Make widely available at home and abroad now the economy energy switch using Be basic to have a voice to control type, touch type, exposed to light etc..This alone of the switch method Be each to have his/her own irregularity, such as voice’s controling a type isn’t suitable for a noisy miscellaneous place, exposed to light switch of environment in the unmanned period not ability auto close.This design passes the AT89C2051 list slice the machine combine a LED lighting technique, red unauthorized biography technique and light feeling technique, scene mode technique and postpone technique etc. to carry out the intelligence control of checking against the clear equipments.The list slice machine shines on to examine electric circuit to check against a peripheral bright degree of clear equipments signal and heat that carry on an examination to release human body signal that give or get an electric shock red unauthorized biography machine’s collect through a light to decide whether bright light; Output and have a dissimilarity to have the PWM signal of getting empty the ratio to control a LED bright degree according to the bright degree of the environment and the mode of the constitution.
