[0032] In a preferred mode of the utility model, the light control / communication multiplexing port circuit includes PNP triode Q1, triode Q6, triode Q28, resistance R81, resistance R29, resistance R25, resistance R82, resistance R18, resistance R83 and diode D3, one end of resistance R29 is connected with the IO port of single-chip microcomputer, the other end of resistance R29 is connected with triode Q6, triode Q6 is also connected with ground and one end of resistance R25 and resistance R82 respectively, the other end of resistance R25 and resistance R81 are both connected with PNP triode Q1, the other end of resistance R81 and PNP triode Q1 are also both connected with VCC_5V, PNP triode Q1 is also connected with resistance R18 and triode Q28 through diode D3 respectively, triode Q28 is connected with the other end of resistance R82 and one end of resistance R83 respectively, the other end of resistance R83 is connected with ground.
[0033] As Figures 2-3As shown, the circuit is a lamp control / communication multiplex port circuit inside the Bluetooth component, and the bus state in actual use, when the lamp control / communication multiplex port circuit needs to be used, the staff can control the bus through an IO port of the single-chip microcomputer, and the bus has the following four states:
