The sensing assembly 12 is mainly used for collecting lighting parameters of an indoor environment, and can be equipped with one or more sensors according to an indoor area or an actual use requirement. The type of sensor includes, but is not limited to, an illuminance sensor, a humidity sensor, a temperature sensor, etc. The illumination sensor is used for acquiring illumination parameters in an indoor environment in real time, wherein the illumination parameters include but are not limited to illumination, illumination uniformity, color temperature, color rendering index and the like; the humidity sensor and the temperature sensor are respectively used for acquiring humidity parameters and temperature parameters of the indoor environment. Optionally, the sensors may be interconnected in a wired or wireless manner, so that the sensors may be cooperatively arranged and share information.
Further, when equipped with one illuminance sensor, the illuminance sensor is preferably mounted on the lighting parameter collection face, area or position, or mounted on the ceiling of the room and directed toward the lighting parameter collection face, area or position.

For example, the sensing component 12 is configured to collect measured lighting parameters of a plurality of collection points in the indoor space, and transmit the measured lighting parameters to the control module 13, so that the control module 13 inputs the measured lighting parameters into a deep neural network for training to obtain a lighting parameter prediction model of any specified position in the indoor space. It should be noted that the control module may train the deep neural network by itself, or may transmit the received measured lighting parameters to an external device (for example, upload to a cloud server) for the external device to train the deep neural network.

The constant illumination model of the BP neural network can be self-adaptive and self-learned, and has strong nonlinear mapping capability and strong generalization capability.
Further, the control module 13 receives the first lighting parameter collected by the sensing component 12, and performs repeated learning training by using the first lighting parameter as an input value of the BP neural network, so as to obtain a prediction model corresponding to the lighting parameter at any specified position (such as any region, any plane, or any point) in the indoor environment and the first lighting parameter. The method comprises the steps of predicting the lighting parameters of any indoor designated position by using the prediction model, reversely predicting theoretical lighting parameters required by a certain designated position according to the lighting parameters in the indoor environment collected in real time, adjusting each lighting assembly by taking the theoretical lighting parameters as target values, generating control signals and sending the control signals to the corresponding lighting assemblies, so that the corresponding lighting assemblies adjust the lighting states of the corresponding lighting assemblies after receiving the control signals until a certain plane, a certain area or a certain position designated indoors keeps preset constant illumination.
