Background technique

At present, in large shopping malls, supermarkets, warehouses, entertainment venues and other occasions where a large number of lighting equipment are used, the switch control of lighting equipment mainly uses contact switches and air switches. For example, directly control a single lighting device by using a mechanical 86-type single-connected one-position single-control switch, 86-type single-connected two-position single-control switch, or use an AC contactor to control a group of lighting devices. It can be seen that the control of multiple lighting devices by the above method is that one switch corresponds to one lighting device, or one switch corresponds to a group of lighting devices, and the direct control of one or some specified lighting devices cannot be realized randomly according to the needs. . Moreover, in the case of the above-mentioned control method with a large area and many lighting devices, the engineering construction is relatively complicated and the wiring cost is high. Therefore, a lighting device control switch with simple construction and low cost is required. the

Finally, control the incandescent lamp of the corresponding serial number to turn on or off. For example, when the microcontroller controls the output of P0.1 of P0 port to 1 and the output of P1.2 of P1 port to 1, the solid state relays SSR2 and SSR11 work, and the controlled output The terminals are respectively connected to 220V alternating current, and correspondingly the two ends of the incandescent lamp connected to the output terminals of the two solid state relays are supplied with 220V alternating current, and the lamp is lit. When the P1.2 output of P1 port is 0, the output terminal of SSR11 is disconnected, and the light goes out.
