The control module is used to output a first control signal according to the adjustment strategy, and the adjustment module is used to adjust the spacing between the lens module and the light-emitting module within the light-emitting area according to the first control signal, so as to automatically adjust the illumination range of the light-emitting module output to the target area under different application scenarios.

Claims

1. A smart lighting fixture, comprising: The system comprises a control module, multiple light-emitting modules, a lens module, an adjustment module, and a scene acquisition module. The light-emitting modules are arranged in an array to form a light-emitting area. Within this area, the adjustment module is positioned on the same side of the light-emitting module's light-emitting path, corresponding to the axis of the light-emitting path. The lens module is mounted on the adjustment module. The control module is connected to both the adjustment module and the scene acquisition module. The scene acquisition module acquires a user's current application scene and outputs it to the control module. The control module selects an adjustment strategy for the smart lighting fixture based on the current application scene. The control module outputs a first control signal to the adjustment module according to the adjustment strategy. The adjustment module adjusts the spacing between the lens module and the light-emitting modules within the light-emitting area based on the first control signal, thereby adjusting the illumination range of the light-emitting modules output to a target area. The adjustment module includes multiple adjustment units, each corresponding one-to-one with each group of light-emitting modules, and positioned on the same side of the light-emitting path of the light-emitting module along its axis. Each adjustment unit includes a lens barrel, a support barrel, a current coil, and a magnetic unit. The lens module is fixedly disposed within the lens barrel, which is fitted within the support barrel. The support barrel has a first opening on its side away from the light-emitting module, allowing the lens barrel to move relative to the light-emitting module under external force.
