this paragraph Single button with human body induction, light sensing, dimming and color matching cool lamp programme , Master chip acquisition use DLT8MA12TS series Touch chip , The package model is 16 Pin SOP, By designing the circuit , The following functions can be realized ：

1. Click the touch button to switch mode ON/AUTO/OFF, The three modes switch back and forth , need 3 individual IO The port carries out status indication , If there is no operation ,15 Seconds later, the indicator light goes out ; 

When in ON In mode LED1 The indicator light is on （15 Seconds later, the indicator light goes out ） Light normally on ; 

When in AUTO In mode LED2 The indicator light is on （15 Seconds later, the indicator light goes out ）, There is one IO Mouth detection PIR The signal , When PIR IO Turn off the light when the electricity is low , When PIR IO The light is on when the port is at high level , Turn off the light when low level is detected , Light up when the level is high ; 

When in OFF In mode LED3 The indicator light is on （15 Seconds later, the indicator light goes out ） The light goes out , At this time, it enters the low power consumption state ; 

2. Double click the touch key to switch the color temperature ,3000k、4000k、5000k Cyclic transformation ;

4. Only in ON And AUTO Color temperature switching and Stepless dimming ;
