As one embodiment, the instruction acquirer includes a touch pad, and the control module works as follows:
the instruction processing module analyzes whether the object touching the touch pad is a human hand, if so, the gesture analysis step is executed, and if not, the action is not executed;
gesture analysis: the instruction processing module analyzes the distribution of the electric signal change of the touch pad, and judges the start/stop instruction and sends the start/stop instruction to the main control module when the electric signal change is positioned at the same position and does not change in a preset time;
when the position of the electric signal changes within the preset time, calculating a brightness change value according to the movement track direction and length of the hand according to the position of the electric signal change on the touch pad, combining the value with the current working brightness of the LED lamp to obtain the new working brightness of the LED lamp, and waking up/sleeping the corresponding LED lamp driving module to enable the LED lamp to be matched with the new working brightness of the LED lamp.
The control module realizes manual control of the brightness of the LED lamp according to the time of touching the touch pad by a person and the sliding path length and direction of the touch pad. For example, when the lamp needs to be turned on or turned off, the instruction processing module can recognize the lamp on/off instruction by only pressing the touch pad for 3 seconds, at this time, the LED lamp is controlled to be turned on if the LED lamp is in the off state, and the LED lamp is controlled to be turned off if the LED lamp is in the on state. When the user feels that the brightness of the LED lamp is too high, the user can slide left on the touch control plate, the brightness of the LED lamp can be continuously reduced along with the sliding of the user until the hand of the user stops acting or leaves the touch control plate, and the corresponding brightness of the LED lamp can be kept unchanged. When the user needs to return the LED lamp to the state of automatically changing brightness, the user only needs to double-click the touch pad or restart the LED lamp.
In order to avoid false triggering, the touch pad includes a temperature identifier and other devices for identifying whether the touched object is a person, and only when the hand of the person touches the touch pad, the touch pad executes the relevant command.

and (3) action analysis: the AI module analyzes a multi-frame picture shot by the camera, captures the position change of the gesture and forms a path, when the gesture is captured to stop for a preset time, the gesture stop position is a path end point, the length of the path is transmitted to the instruction processing module, the instruction processing module calculates the value of the brightness change according to the direction and the length of the path, then the value is combined with the current working brightness of the LED lamp to obtain the new working brightness of the LED lamp, and the LED lamp is enabled to be matched with the new working brightness of the LED lamp by waking up/dormancy of the corresponding LED driving module.
The invention can be realized by adopting a camera besides manual control by adopting a touch pad, namely, the camera shoots gestures of a user to execute related commands. In order to avoid the wrong recognition, the user needs to put a specific gesture to recognize the camera, for example, the user firstly opens the palm and combines the five fingers in front of the camera, the AI module judges that the user needs to adjust the brightness, then the user swings the hand to the left, namely judges that the brightness is reduced, and the swing path also determines the brightness change.
The invention can be used as manual control from one of the two, and can also be used as manual control in a combined mode, so that a user can realize the effect of controlling the LED lamp at different positions.
In this embodiment, the main control module stores the lowest brightness state, and when the brightness change value is negative and the absolute value of the brightness change value is greater than the current working brightness value of the LED lamp, the main control module controls the lamp ring 2 located at the innermost ring to illuminate with the lowest brightness, so as to avoid the LED lamp from being directly extinguished in the brightness control process.
In this embodiment, the brightness variation manner of the LED lamp is as follows:
when L 1 Is positioned in the brightness range L where the current position is m The brightness of the lamp ring 2 is dependent on L 1 And changes;
when L 1 Beyond the brightness range L in which the current position is m When in use, the main control module is used for controlling the operation of the computer according to L 1 Within a brightness range L m+1 Or L m-1 While controlling the lamp ring 2 corresponding to wake up to work at the lowest brightness/highest brightness and along with L 1 Continuously becoming larger or smaller to control the wake-up lamp ring 2 to continuously lighten/darken, and simultaneously control L m The corresponding lamp ring 2 is dimmed/lightened to achieve the effect of smoothly switching the operating lamp ring 2.
When the brightness changes across two brightness ranges, the invention adopts the effect that the brightness of different lamp rings 2 is changed simultaneously, so as to realize the whole brightness smoothing effect of the LED lamp and avoid discomfort to eyes of a user caused by overlarge brightness change.
The present invention is not limited to the preferred embodiments, but is intended to be limited to the following description, and any modifications, equivalent changes and variations in light of the above-described embodiments will be apparent to those skilled in the art without departing from the scope of the present invention.
