[0020] Reference Figure 1 , Figure 2 and Figure 3This utility model provides a motion-sensing lamp based on human-sensing light perception. The lamp includes a housing 110, a black semi-transparent lens, an ambient light detection device, a human body detection control device, a light output device, and a signal processing system. The housing 110 has a sensing hole 111 and a light emission hole 112. The black semi-transparent lens is disposed on the sensing hole and connected to the housing on all sides, making the lamp an integrated unit. The ambient light detection device, human body detection control device, light output device, and signal processing system are all disposed within the inner cavity of the housing. The input terminal of the signal processing system is connected to the output terminals of the human body detection control device and the ambient light detection device, and the output terminal of the signal processing system is connected to the input terminal of the light output device. The ambient light detection device includes an ambient light sensor, and the human body detection control device includes a human body sensor. Both the ambient light sensor and the human body sensor face the inner side of the black semi-transparent lens. The light output device includes several LEDs, which face the light emission hole.

[0021] In this embodiment, the human body sensor can be an infrared sensor, such as an NS612 chip. The ambient light sensor can be a photodiode. When the sensor light is applied, the initial application process is as follows: To activate the lighting setting: First, install the sensor light in the desired ambient light level. Then, shine a flashlight on the photodiode. Within 12 seconds of the sensor light being powered on, move your hand back and forth across the photodiode 8 times (once every 0.6 to 1.2 seconds). The light will then flash 4 times as a notification. After that, turn off the flashlight. It will automatically memorize the current ambient light level after 5 seconds, indicating that the setting is complete.

[0022] Workflow: When the ambient light detected by the ambient light sensor exceeds the activation threshold set by the signal processing system, the signal of the human body sensor control device will be turned off, the light output device will not turn on, and the light will not illuminate. When the ambient light detected by the ambient light sensor is below the activation threshold set by the signal processing system, the human body sensor control device will detect a person and trigger the light output device to turn on through the signal processing system, illuminating the light. The light will automatically turn off 15 seconds after the person leaves the sensing range of the human body sensor.

[0023] It is understood that in this embodiment, the human body sensor and the ambient light sensor share a single optical lens, thereby improving the overall aesthetics and integrity of the sensor light and making it applicable to more scenarios. The optical lens in this embodiment is a black semi-transparent lens, which can be a black semi-transparent Fresnel lens. The lens in this embodiment can be pre-adjusted using a scientific formula ratio, mixing black pigment and transparent material to increase the light transmittance to 80% while maintaining the original black appearance of the lens. This allows the internal human body sensor and ambient light sensor to maintain their original working performance while sharing a single lens.

[0024] It is understandable that, such as Figure 4 As shown, the ambient light sensing detection device of this embodiment includes a photodiode RG1, a first resistor R1, and a control chip T2. The negative terminal of the photodiode RG1 is grounded, the first end of the first resistor R1 is connected to the positive terminal of the photodiode RG1, and the power supply terminal of the control chip T2 and the second end of the first resistor R1 are both connected to the input terminal of the signal processing system. The connection point between the first end of the first resistor R1 and the positive terminal of the photodiode RG1 is connected to the output terminal of the control chip T2. The enable terminal of the control chip T2 is grounded through a switch K1. When the photodiode in this embodiment senses a preset intensity of light, it will be in a conducting state, thereby directly grounding the external power supply. This causes the signal processing system to output a low level to the light output device, thus keeping the LED beads of the light output device in a continuously de-energized state. Specifically, the control chip in this embodiment can be an existing integrated control chip that can achieve the functions of this embodiment.

[0025] It is understandable that, such as Figure 4 As shown, the ambient light sensing detection device in this embodiment also includes a first capacitor C1. The first end of the first capacitor C1 is connected to the power supply terminal of the control chip T2, and the second end of the first capacitor C1 is connected to the ground terminal of the control chip T2. This embodiment effectively reduces signal interference by connecting a capacitor in parallel.

[0026] It is understandable that, such as Figure 4As shown, the human body sensing control device in this embodiment includes an infrared sensor PIR, a third resistor R3, a fourth resistor R4, and a sixth resistor R6. The first terminal of the infrared sensor PIR is connected to the enable terminal of the control chip T2 via a second resistor R2. The second terminal of the infrared sensor PIR is connected to the input terminal of the signal processing system. The sixth terminal of the infrared sensor PIR is grounded. The first terminal of the third resistor R3 is connected to the second terminal of the infrared sensor PIR. The second terminal of the third resistor R3 is connected to the fifth terminal of the infrared sensor PIR and then grounded via a second capacitor C2. The first terminal of the fourth resistor R4 is connected to the second terminal of the infrared sensor PIR. The second terminal of the fourth resistor R4 is connected to the third terminal of the infrared sensor PIR and then grounded via a fifth resistor R5. A third capacitor C3 is connected in parallel with the fifth resistor R5. The first terminal of the sixth resistor R6 is connected to the second terminal of the infrared sensor PIR, and the second terminal of the sixth resistor R6 is connected to the fourth terminal of the infrared sensor PIR. In this embodiment, when the infrared sensor detects a person passing by, it sends an electrical signal to the signal processing system. This causes the signal processing system to output a high-level signal to the lighting output device, thereby controlling the LEDs in the lighting output device to perform the illumination process, automatically turning off after a preset illumination time. This embodiment effectively reduces signal interference and improves the stability of the electrical signal through capacitor grounding.

[0027] It is understandable that, such as Figure 4 As shown, the human body sensing control device in this embodiment further includes a fourth capacitor C4 and a fifth capacitor C5. The first terminal of the fourth capacitor C4 is connected to the second terminal of the infrared sensor PIR, and the second terminal of the fourth capacitor C4 is grounded. The first terminal of the fifth capacitor C5 is connected to the second terminal of the infrared sensor PIR, and the second terminal of the fifth capacitor C5 is grounded. This embodiment, by connecting a capacitor to each port, can effectively improve the stability of the electrical signals sent by the infrared sensor to the signal processing system, thereby improving the stability of the lamp bead on / off control process.

[0028] It is understandable that, such as Figure 4 As shown, the signal processing system of this embodiment includes a voltage regulator chip T1. The input terminal of the voltage regulator chip T1 is connected to the second terminal of the infrared sensor PIR, the power supply terminal of the control chip T2, and an external power supply (3.3V). The output terminal of the voltage regulator chip T1 is connected to the input terminal of the lighting output device. The voltage regulator chip in this embodiment can be an existing integrated voltage regulator chip, such as the 7533 chip. This embodiment sends electrical signals to the lighting output device through the voltage regulator chip, thereby effectively improving the stability of the electrical signals.

[0029] It is understandable that, such as Figure 4As shown, the signal processing system in this embodiment also includes a sixth capacitor C6, a seventh resistor R7, and a first diode D1. The first terminal of the sixth capacitor C6 is connected to the output terminal of the voltage regulator chip T1, and the second terminal of the sixth capacitor C6 is grounded. The first terminal of the seventh resistor R7 is connected to the output terminal of the voltage regulator chip T1, the cathode of the first diode D1 is connected to the second terminal of the seventh resistor R7, and the anode of the first diode D1 is connected to the input terminal of the lighting output device. This embodiment effectively reduces interference in the output signal of the signal processing system through the sixth capacitor, and prevents the LED beads in the lighting output device from breaking down by reversing the connection of the first diode, thereby improving the stability of the LED beads in the lighting output device.

[0030] It is understandable that, such as Figure 4 As shown, the light output device in this embodiment includes a first light-emitting diode (LED1), a second light-emitting diode (LED2), and a third light-emitting diode (LED3). The positive terminal of the first LED1 is connected to the positive terminal of the first diode (LED1), the positive terminal of the second LED2 is connected to the negative terminal of the first LED1, the positive terminal of the third LED3 is connected to the negative terminal of the second LED2, and the negative terminal of the third LED3 is grounded.
