The coding signal sent by the coding chip PT2262 is a complete code word formed by an address code, a data code and a synchronous code. After the decoding chip PT2272 receives the signal, the VT pin outputs a high level after the address code is compared and checked twice, and at the same time, the corresponding data pin also outputs a high level.
Pressing down a highlight button on the remote controller, and sending out a wireless signal after PT2262 codes; after receiving the wireless signal, the PT2272 circuit performs corresponding decoding, at this time, the pin 13 of the PT2272 outputs a high level, and is connected to the resistor R16 in fig. 5 and added to the ADJ pin of the chip U1 in fig. 5, and at this time, the controlled induction lamp is in a forced highlight state. Only when the 'sensing' button on the remote controller is pressed, the PT2262 codes and then sends out the wireless signal again, the PT2272 decodes after receiving the wireless signal, the 13 pin of the PT2272 outputs low level, the level of the ADJ pin of the U1 is controlled by the sensing device at the moment, and the controlled sensing lamp releases the forced highlight state.
