A correspondence table of the ambient luminance interval and the preferred luminance value corresponding to the interval is stored in the memory 70. In the correspondence table, the ambient brightness value is divided into several ambient brightness intervals, such as dark, dark, normal, bright, and bright. Each of the different ambient brightness intervals corresponds to a preferred LED lamp brightness value.

The communication unit 60 can be used to connect other LED lights to enable communication between the LED lamp 1 and other LED lamps. The communication unit 60 can be a wireless communication or a wired communication unit.

The power source 20 is connected to the power management unit 50. The power source 20 can be a battery or an AC/DC adapter module. The power management unit 50 is connected to the processing unit 10, the brightness sensing unit 30, the motion sensing unit 40, and the communication unit 60, respectively, and distributes operating voltages thereto. In the present embodiment, when the LED lamp 1 is connected to the power source 20, the power management unit 50 distributes the operating voltage to the processing unit 10 and the motion sensing unit 40, so that the processing unit 10 and the motion sensing unit 40 are in an active state. It is not possible to power other components to make them inactive.

The brightness sensing unit 30 is configured to detect current ambient brightness information and transmit the detected ambient brightness information to the processing unit 10.

The motion sensing unit 40 can be an infrared sensing unit or an ultrasonic sensing unit. The infrared sensing unit detects the activity of a certain person in a certain range by using infrared rays radiated by the human body, and the ultrasonic sensing unit detects the movement of the human body by ultrasonic waves to determine whether there is a certain range within a certain range. If the motion sensing unit 40 detects the activity of a person in a certain range around, the motion sensing unit 40 generates an inductive trigger signal and transmits The processing unit 10 is connected to it.

After receiving the sensing trigger signal, the processing unit 10 controls the power management unit 50 to allocate a voltage to the brightness sensing unit 30, thereby turning on the brightness sensing unit 30. The brightness sensing unit 30 transmits the detected ambient brightness information to the processing unit 10. The processing unit 10 converts the ambient brightness information into an ambient brightness value by analog-to-digital conversion, and determines an ambient brightness interval in which the ambient brightness value is located and a preferred brightness value corresponding to the interval from the correspondence table of the memory 70, and processes The unit 10 controls the LED bead 80 to emit light according to the obtained preferred brightness value, and generates the communication control signal, and the communication control signal is transmitted to the other LED lamps through the communication unit 60.

When the LED lamp bead 80 is in the working state, the processing unit 10 starts timing when the motion sensing unit 40 detects a person within a predetermined range, and when no time is detected within a predetermined range for a predetermined period of time, the processing unit 10 transmits Upon turning off the control signal to the power management unit 50, the power management unit 50 stops allocating the operating voltage to the LED bead 80 in accordance with the shutdown control signal. The predetermined time period may be stored in the memory 70 by the system preset, or may be set by the user through the input unit 80.

After receiving the communication control signal transmitted by the other LED lamps, the processing unit 10 controls the power management unit 50 to allocate a voltage to the brightness sensing unit 30, thereby turning on the brightness sensing unit 30. The brightness sensing unit 30 transmits the detected ambient brightness information to the processing unit 10. The processing unit 10 converts the ambient brightness information into an ambient brightness value by analog-to-digital conversion, and determines an ambient brightness interval in which the ambient brightness value is located and a preferred brightness value corresponding to the interval from the correspondence table of the memory 70, and processes Unit 10 controls LED lamp bead 80 to illuminate based on the obtained preferred brightness value.

In other embodiments of the present invention, the processing unit 10 only needs to detect the presence of a person within a predetermined range in the motion sensing unit 40, and the ambient brightness sensed by the brightness sensing unit 30. When the information is lower than a standard value, the LED lamp bead 80 can be controlled to emit light without controlling the brightness of the LED lamp bead 80. This standard value can be stored in advance in the memory 70. That is, the processing unit 10 detects a person within a predetermined range in the motion sensing unit 40, and controls the LED lamp bead 80 to emit light according to the ambient brightness information sensed by the brightness sensing unit 30.
