[0057] The lighting unit comprises a driving circuit and an LED lamp group. The driving circuit adopts a down-tube driving structure and is connected to the main control unit, and the input high-level circuit is turned on.

[0058] The LED light group is connected to the driving circuit. In one embodiment, the LED light group includes three kinds of lamp beads (RGB lamp beads): red, green and blue.

[0067] 3. Manually turn on / off the Local Routine function. A button is provided on the side of the smart lamp 100 with ambient light detection and human infrared detection. Press once to turn on / off the Local Routine function. Red means off, and green means on.

[0073] 6. Set the color and color temperature of smart lamps 100 with ambient light detection and human infrared detection through the Matter protocol.

[0074] 7. Adjust the brightness of the smart lamp 100 with ambient light detection and human infrared detection through the Matter protocol.

[0075] 8. The firmware of the smart lamp 100 with ambient light detection and human infrared detection can be upgraded through the Matter protocol.

[0076] Figure 3 This is a network topology diagram of the smart lamp 100 with ambient light detection and human infrared detection. The system consists of four parts: 3R-Installer, router (WiFi Router), third-party Matter protocol and smart lamp 100 with ambient light detection and human infrared detection. First, the user configures the smart lamp 100 with ambient light detection and human infrared detection to access the network through 3R-Installer. The user can identify the smart lamp 100 with ambient light detection and human infrared detection on the mobile phone App and bind the device. The user can also set the color, brightness, color temperature, control mode and other parameters of the smart lamp 100 with ambient light detection and human infrared detection through the mobile phone App. The control command WiFi Router sends data to the smart lamp 100 with ambient light detection and human infrared detection through the wireless communication interface. After receiving the data, the smart lamp 100 with ambient light detection and human infrared detection finally performs the corresponding operation.

[0077] After the smart lamp 100 with ambient light detection and human infrared detection is configured and connected to the network, the user can share the smart lamp 100 with ambient light detection and human infrared detection with the third-party Matter protocol through the Multi-Admin function of the Matter protocol, and can also set the color, brightness, color temperature, control method and other parameters of the smart lamp 100 with ambient light detection and human infrared detection through the third-party Matter protocol, and control the WiFi Router to send data to the smart lamp 100 with ambient light detection and human infrared detection through the wireless communication interface. After receiving the data, the smart lamp 100 with ambient light detection and human infrared detection finally performs the corresponding operation.

[0078] The communication unit interface of the smart lamp 100 with ambient light detection and human infrared detection obtains the control command sent by the WiFi Router. The main control unit first performs protocol analysis, decomposes the light color command into the mixed ratio of the three primary colors of red, green and blue, and then the color control pin corresponding to the single-chip microcomputer outputs a pulse width signal to drive the corresponding lamp beads, thereby achieving a color change effect. The brightness adjustment is achieved by increasing or decreasing the pulse width signals of the red, green and blue three-way drivers in equal proportions to achieve brightness adjustment under the same color.

[0079] The single chip microcomputer reads the data of the light sensor 2 through the IIC interface. When the ambient light changes, the single chip microcomputer automatically adjusts the brightness of the lamp beads according to the intensity of the ambient light. The user can also set a trigger threshold to automatically turn on or off the smart lamp 100 with ambient light detection and human infrared detection.

[0080] The microcontroller reads the data of infrared sensor 1 through IRQ. When infrared sensor 1 detects a person, the microcontroller combines the data of light sensor 2 to automatically turn on or off the night light.

[0081] However, the following two situations may cause the light sensor 2 detection function to fail:

[0082] When the ambient light becomes darker, the smart lamp 100 with ambient light detection and human infrared detection automatically lights up. At this time, if there are strong reflective materials (such as white walls, mirrors, etc.) around the smart lamp 100 with ambient light detection and human infrared detection, the strong light reflection will cause the smart lamp 100 with ambient light detection and human infrared detection to automatically turn off, causing the device to enter an abnormal working state of continuous opening and closing. In order to avoid this situation, we have carried out a specific software algorithm, the specific principle is as follows: before sensing that the ambient light is dimming and the light needs to be turned on, the light intensity is detected before turning on the light, and the light intensity is detected again after turning on the light, by increasing the light intensity threshold, and on this basis, the light flux is calculated to increase and then the smart lamp 100 with ambient light detection and human infrared detection is turned off again. Thereby avoiding the failure of the light sensor 2 to detect due to different reflective conditions.

[0083] When the night light is in a dim environment and the user is playing TV, the surrounding light environment will change rapidly. In order to avoid the flickering of the smart lamp 100 with ambient light detection and human infrared detection in this usage scenario, an anti-shake mechanism of the light sensor 2 is added. In the process of detecting the change of ambient light, the light intensity needs to be stable for a period of time before the automatic switch function of the light is activated.

[0084] The utility model fundamentally overcomes the shortcomings of smart lamps on the market, such as the low degree of intelligence. At present, most smart lamps on the market are simply triggered manually, sound-triggered or human infrared induction triggered, and most of them do not have communication interfaces, and cannot access the ecological chain of the Matter protocol. It is impossible to support multiple protocols at the same time. Most smart lamps on the market cannot support Zigbee / WiFi / Thread / BLE protocols at the same time. In addition, the smart lamps on the market cannot join the ecological chains of multiple platforms at the same time, and cannot support the ecological chains of mainstream platforms such as Apple / Google / Amazon / SmartThing at the same time. Moreover, the existing smart lamps have a single color, and most smart lamps have only a single color and cannot adjust the color. At present, most smart lamps on the market do not have the functions of ambient light detection and human infrared detection. The brightness of most smart lamps 100 is open-loop control, and it is impossible to automatically adjust the brightness according to the ambient light, and it is even more impossible to detect whether someone is passing by, so as to turn on / off the smart lamps 100 with ambient light detection and human infrared detection.

[0085] In addition, in practice, some scenes require more sensitive detection, while some scenes require more insensitive detection. The motion detection unit of the present invention can flexibly set its trigger sensitivity to meet the usage requirements in different scenes.

[0086] The infrared sensitivity of the motion detection unit is adjusted as follows Figure 5 As shown, the main control chip outputs a pulse width signal to the sensitivity control chip. It usually outputs a high level. When the sensitivity needs to be adjusted, it is first pulled down for 50ms, and then the signal is pulled up. The duration of the high level corresponds to the sensitivity of the sensor. The longer the time, the higher the sensitivity. Finally, the signal is pulled down for 50ms, and the sensitivity configuration is completed. The duration of the high level is 10ms to 100ms, corresponding to 1 to 10 gears respectively. The control chip adjusts the power supply of the infrared sensor through the PIR VCC pin to adjust the sensitivity of the internal detection sensitive element. The detection sensitive element transmits the sensed human movement signal to the AD chip. The longer the pulse width duration, the longer the sensor continues to sense. The more external pyroelectric infrared radiation energy is continuously received by its internal sensitive element, the easier it is to trigger the detection. The infrared sensor 1 then outputs the detection signal through filtering, etc. The main control unit detects the output signal of the infrared sensor 1 through the GPIO port to determine whether human movement is detected.

[0087] Users can set the sensitivity level on the APP software, and then transmit the data to the main control unit wirelessly. The main control unit converts the sensitivity data into a pulse width signal to achieve sensitivity adjustment.

[0088] The utility model is based on the technical defects of smart lamps on the market, and thus designs a smart lamp 100 with ambient light detection and human infrared detection. The smart lamp 100 uses a wireless communication interface to establish a connection with the Matter protocol using the Matter protocol. Users can use devices that support the Matter protocol (APP or voice control device) to control the switch, brightness, color temperature and color of the smart lamp 100. The smart lamp 100 also has a light feedback function, which can automatically adjust the brightness according to the ambient light. The smart lamp 100 also has an infrared detection function, which can detect whether someone passes by and automatically control the switch of the smart lamp 100 with ambient light detection and human infrared detection.

[0089] The smart lamp 100 with ambient light detection and human infrared detection of the utility model has a high degree of intelligence and can be connected to the ecological chain of the Matter protocol through a wireless communication interface. The Matter protocol is compatible with wireless protocols such as Zigbee, WiFi, Thread, BLE, etc. The ecological chain of mainstream platforms such as Apple / Google / Amazon / SmartThing supports the Matter protocol. The smart lamp 100 can easily adjust the color and temperature according to the RGB three-color lamp bead mixing light. The light detection unit can automatically adjust the brightness according to the ambient light, and the motion detection unit can detect whether someone is passing by, thereby turning on / off the smart lamp 100 with ambient light detection and human infrared detection. Low power consumption and energy saving and environmental protection.
