[0030] Please refer to Figure 1 , which is a structural block diagram of a lamp control circuit based on 433 wireless transmission provided by an embodiment of the utility model.

[0031] The utility model proposes a lamp control circuit based on 433 wireless transmission, which is applied to a lamp system, and includes a 433 wireless transmission module, a control module, an AD-DC power supply module, a PIR module, an IC module, a light sensing module and a key module; wherein the control module is electrically connected to the 433 wireless transmission module, the light sensing module, the IC module and the key module respectively, and the IC module is also electrically connected to the AD-DC power supply module through the PIR module, and the 433 wireless transmission module adopts a 433 wireless transmission chip of the LT4455 type.

[0032] Specifically, the 433 wireless transmission module uses the 433MHz frequency band for wireless communication. The distance of 433MHz wireless transmission is usually about 2 kilometers to 3 kilometers. The wireless transmission module of this frequency has a longer transmission distance, stronger penetration and diffraction capabilities, and smaller transmission process attenuation, which can meet the needs of long-distance data transmission. And 433MHz wireless transmission has no obvious directionality, the coverage of signal transmission is relatively wide, and there is no need to consider the transmission direction of the signal too much during data transmission. The normal working mode of 433MHz technology will only establish a wireless link when there is data transmission, so it greatly reduces the interference to other devices in the network, and also reduces the power consumption of the device itself, and supports point-to-point and point-to-multipoint wireless data communication methods, with the advantages of integrated transceiver, safe isolation, installation isolation, simple use, high cost performance, stable and reliable. In contrast, the transmission distance of the 2.4GHz wireless module is shorter, generally within 10 to 30 meters, and its signal attenuation is large, and its penetration and diffraction capabilities are weak.

This type of transistor is similar in structure to connecting a photodiode between the base and collector of an ordinary transistor, where the current generated by the photodiode is equivalent to the base current of the transistor. Due to its current amplification effect, the phototransistor is more sensitive than the photodiode and can output a larger photocurrent at the collector.
