[0049] The present application is further described in detail below in conjunction with the accompanying drawings.

[0050] In one embodiment, if Figure 1 As shown, the present application discloses a zoom adjustment method for an LED lamp, which specifically includes the following steps:

[0051] S10: respectively obtaining the position of each LED lamp and the corresponding irradiation position, and calculating the irradiation distance and irradiation deviation angle between the LED lamp and the irradiation position.

[0052] Specifically, the position of the LED lamp and the corresponding irradiation position, including the distance between the LED lamp and the ground, the distance between the LED lamp and the irradiation position, and the distance between the irradiation position and the ground, are obtained through infrared sensors pre-installed on each LED lamp, so as to obtain the straight-line irradiation distance between the LED lamp and the irradiation position. The irradiation deviation angle is the angle between the light direction of the LED lamp and the vertical line of the ground.

[0053] S20: Calculate the optimal irradiation beam angle of the LED lamp according to the irradiation distance and the irradiation deviation angle, and adjust the current irradiation beam angle between the LED lamp and the irradiation position in combination with the expected ideal irradiation value.

[0072] S402: According to the adjusted beam angle, the LED lamp is adjusted to reduce the limit of illumination, and the adjustment correlation between the beam angle change and the reduction ratio of the LED lamp's illumination intersection area is analyzed.

[0073] Specifically, adjacent LED lamps are adjusted to reduce the limit of illumination respectively according to the adjusted beam angle, that is, the illumination angle of each LED lamp is reduced to eliminate the illumination intersection area, and in the process of changing the LED illumination beam angle, the corresponding relationship between the beam angle change of the LED lamp and the corresponding change in the reduction ratio of the illumination intersection area is obtained, thereby obtaining the adjustment correlation relationship between the beam angle change and the reduction ratio of the illumination intersection area of ​​the LED lamp.

[0074] S403: Using the adjustment association relationship and the zoom adjustment data of each LED lamp as training samples for data training, and constructing an adjustment control model for the LED lamp.

[0075] Specifically, the adjustment association relationship and the zoom adjustment data of each LED lamp are used as training samples, and the association points between the adjustment association relationship and the zoom adjustment data are obtained through big data training. The adjustment association relationship and the zoom adjustment data are data-associated to construct an adjustment control model for the LED lamp.
