Therefore, the processor needs to determine multiple conditions to exclude the influence of the light emitting of the light emitting device on the detection of the photosensitive sensing device on the external environment state whether lighting is needed, thereby increasing the complexity and time of information processing and reducing the response rate of the lamp.

[0051] The use of "adapted for" or "configured for" herein means open and inclusive language that does not exclude devices adapted for or configured for performing additional tasks or steps.

[0052] Generally, the intelligent lighting device includes a light emitting device, and one or more of a sound sensor device, an infrared human sensor device, a microwave sensor device, and a light sensitive sensor device. The light emitting device is controlled by multiple judgments of these sensor devices.

[0053] In an example, the light-sensitive sensing device and the light-emitting device are structurally isolated to avoid the light-emitting device affecting the light-sensitive sensing device in determining whether the current environment is in a light state or a dark state, so that the smart lighting device can turn on the light in a dark environment and turn off the light in a light state. The application scenario of the smart lighting device with such a structure is single. If it is in a dark environment without people, it is in a constant bright state, which is contrary to the original intention of researching energy-saving and environment-friendly smart lighting devices.

[0054] In another example, the light-sensitive sensing device and the light-emitting device are not structurally isolated in the smart lighting device. Based on the detection of the light intensity of the current environment by the light-sensitive sensing device, the detection information of at least one of the sound sensing device, the infrared human sensing device, or the microwave sensing device, such as the fluctuation signal of the sound wave, the infrared signal radiated by the human body, or the fluctuation signal of the microwave, is also needed to make the light-sensitive sensing device exclude the influence of the light-emitting device, so that the smart lighting device can turn on the light in a dark environment and turn off the light in a light state. The smart lighting device with such a structure needs multiple judgment conditions, and the control method and structure are complex, occupy a large space, and are not conducive to the application of the smart lighting device in various scenarios.

[0055] Therefore, as shown in Figure 1 some embodiments of the present application provide a smart lighting device 1000. In an example, the smart lighting device 1000 can be a smart tube light, a spotlight, a light strip, or any device with a smart lighting function, such as a street lamp. The specific form of the smart lighting device 1000 is not specially limited in the embodiments of the present application. In an example, the smart lighting device 1000 is a lamp 1001.

[0056] As shown in Figure 2 and Figure 3 the lamp 1001 includes a light-sensitive sensing unit 100, a processor 200, and a light-emitting device 300.

[0057] The light-sensitive sensing unit 100 is configured to detect the light intensity of the environment. In an example, as shown in Figure 3 the light-sensitive sensing unit 100 includes a light-sensitive sensing element 101, a resistor R4, and a capacitor C1. The resistor R4 is configured to protect the light-sensitive sensing element 101 from being broken by a large current. The light-sensitive sensing element 101 includes a photoresistor or a photo triode, for example, the light-sensitive sensing element 101 is a photo triode. The light-sensitive sensing element 101 adjusts the current passing through itself according to the light intensity of the environment it senses, to adjust whether the light-sensitive sensing unit 100 transmits an electrical signal or the size of the electrical signal.

[0058] The processor 200 is electrically connected to the light-sensitive sensing unit 100. In an example, as shown in Figure 3As shown, the processor 200 includes a single-chip microcomputer U2, a capacitor C2, and a resistor (not shown in the figure), etc.

[0059] The light emitting device 300 is electrically connected with the processor 200. As shown, Figure 3 As shown, the light emitting device 300 includes a plurality of Light Emitting Diode (LED) lamps and a resistor R2, etc.

[0060] The processor 200 is configured to control the on-off frequency F1 of the lamp 1001 to be a first frequency and a second frequency F2. When the lamp 1001 emits light at the first frequency F1, and the light sensitive sensing unit 100 detects that the ambient light intensity is less than a first threshold M1, the counting is started; and the number N of times that the light sensitive sensing unit 100 detects that the ambient light intensity is less than the first threshold M1 within a set time T0 is recorded. The first threshold M1 is a critical value of the ambient light intensity required for the lamp 1001 to emit light.

[0061] Further, the processor 200 determines whether the number N is greater than a second threshold according to the counted number N. The second threshold M2 is the minimum number of times that the light sensitive sensing unit 100 detects that the ambient light intensity is less than the first threshold M1 in response to the user operation to generate a control signal, i.e., the minimum number of times that the lamp 1001 needs to be turned on at the second frequency F2. In this way, when the number N is less than or equal to the second threshold M2, the processor 200 controls the light emitting device 300 to be turned off or not to emit light; when the number N is greater than the second threshold M2, the processor 200 controls the light emitting device 300 to emit light at the second frequency F2. For example, the second threshold M2 is 1 to 3 times, e.g., 1, 2 or 3 times. In this way, the second threshold M2 takes into account the influence of the activity frequency of a certain substance on the number of times that the lamp 1001 is blocked, which can reduce the probability that the lamp 1001 is turned on in a dark environment without human activity due to accidental factors, thereby achieving the effect of energy saving.

[0062] There is no structural isolation between the light sensitive sensing unit 100 and the light emitting device 300, and the light sensitive sensing unit 100 can detect the ambient light intensity in the current environment other than the light intensity emitted by the light emitting device 300, which can be applied to various sizes of lighting devices 1000, especially small night lights, downlights, etc.

[0063] In some embodiments, as shown in Figure 2 and Figure 3 The lamp 1001 further includes an infrared sensing unit 400, which is electrically connected with the processor 200. The infrared sensing unit 400 is configured to sense whether there is a human body sensing signal (a human or an animal, etc. having a certain temperature can radiate infrared rays) in the surrounding space of the environment where the lamp 1001 is located. For example,Figure 3 As shown, the infrared sensing unit 400 includes a passive infrared (PIR) sensor, a capacitor, a resistor (not shown in the figure), and the like.

[0064] Thus, on the basis that the lamp 1001 includes the photosensitive sensing unit 100 and the infrared sensing unit 400,

[0065] The processor 200 takes the first time length T1 as a period, collects the human body sensing signal once per period; if the human body sensing signal is not collected, the lamp 1001 is controlled to be turned off.

[0066] If the human body sensing signal is collected, the lamp 1001 is controlled to enter the photosensitive mode. The lamp 1001 continues to emit light at the second frequency F2 for the second time length T2; every second time length T2 interval, the lamp 1001 emits light at the first frequency F1 for the third time length T3. Wherein, in the third time length T3, it is judged whether the number of times N is greater than the second threshold M2. If yes, the lamp 1001 continues to emit light at the second frequency F2; if no, the lamp 1001 is controlled to be turned off.

[0067] In some embodiments, as shown in Figure 2 and Figure 3 As shown, the lamp 1001 further includes a power supply processing module 500, the power supply processing module 500 is electrically connected with the external power supply E, the photosensitive sensing unit 100, the infrared sensing unit 400, the processor 200 and the light emitting device 300, and the power supply processing module 500 is configured to process and transmit the electrical signal of the external power supply E to each component electrically connected therewith.

[0068] As shown in Figure 3 The power supply processing module 500 includes a power supply protection circuit 501, a rectifier filter circuit 502, a power management circuit 503, a voltage stabilizing circuit 504 and a detection circuit 505.

[0069] The power supply protection circuit 501 includes a fuse F1 and a voltage-dependent resistor VR1, and the like, and is configured to prevent the external voltage or current from fluctuating too much to cause short circuit or other abnormalities of the entire circuit.

[0070] The rectifier filter circuit 502 includes a bridge stack BD1, a capacitor EC1 and a delay resistor R1, and the like, and is configured to convert the alternating current output by the power supply protection circuit 501 into direct current and transmit it to the power management circuit 503. The delay resistor R1 is configured to delay the time when the anode of the light emitting device 300 receives the electrical signal, so as to provide a certain time for photosensitive and infrared sensing operation.

[0071] The power management circuit 503 includes a power management IC (PMIC), capacitors C4 and C5, resistors (not shown in the figure), and the like, and is configured to transmit a power signal to the entire circuit according to a control signal of the processor 200. Among them, the current can be transmitted to the light emitting device 300, and the voltage is transmitted to the voltage stabilizing circuit 504.

[0072] The voltage stabilizing circuit 504 includes a low-dropout linear voltage regulator (LDO) U1, a capacitor C3, a resistor R3, and the like, and is configured to perform voltage reduction and voltage stabilization processing on the electrical signal transmitted by the power management circuit 503, and output to the processor 200. For example, the voltage output by the power manager 503 to the voltage stabilizing circuit 504 is 5.5V, and the voltage output after LDO processing is 3V.

[0073] The detection circuit 505 includes at least two resistors R7 and R8, a capacitor (not shown in the figure), and the like. The detection circuit 505 and the processor 200 jointly act on the received electrical signal to generate a pulse width modulation (PWM) signal and transmit it to the light emitting device 300 to adjust the frequency of the light emitting device 300. For example, according to the signal transmitted by the light-sensitive sensing unit 100 and the infrared sensing unit 400, the working frequency of the light emitting device 300 is adjusted from the first frequency F1 to the second frequency F2 to emit light, or from the second frequency F2 to the first frequency F1 to emit light. Among them, the voltage after LDO processing is not stored through the capacitor and then transmitted to the light emitting device 300, and there is no need for linear driving to stabilize the voltage and current of the light emitting device 300. Instead, the PWM signal is transmitted to the processor 200 to generate a PWM signal, and the working state of the light emitting device 300 is adjusted through the PWM signal, so that the light emitting device 300 will not be affected by other electrical signals in the entire circuit. Emit light to improve the accuracy of intelligent sensing of the lamp 1001.

[0074] Therefore, the processor 200 is also configured to, in the case that the power processing module 500 is initially electrically connected with the external power source E, control the lamp 1001 to flash at the first frequency F1 for a fourth time length T4, wherein the set time length T0 is less than the fourth time length T4. This is because the lamp 1001 has a transition phase when it is initially powered on. The application utilizes this transition phase to determine whether the current environment requires the light to be on, further improving the response rate of the lamp 1001.

[0075] As shown in the following Figure 4 and Figure 5 The application provides a control method of a lamp 1001. The control method includes S100-S200.

[0076] S100, asFigure 4 As shown, after power-on, the processor 200 controls the on-off frequency of the lamp 1001 to be the first frequency F1. The lamp 1001 flashes and emits light at the first frequency F1 for a fourth time duration T4, wherein the set time duration T0 is less than the fourth time duration T4. This is because the lamp 1001 has a response time of a lower frequency operation after initial power-on.

[0077] For example, the first frequency F1 ranges from 100 Hz to 300 Hz. For example, the first frequency F1 is 100 Hz, 150 Hz, 200 Hz or 300 Hz. The fourth time duration T4 is 3 seconds. In the case that the first frequency F1 is 100 Hz, the lamp 1001 emits light at a frequency of 100 Hz for 3 seconds, and the human eye cannot perceive the flicker of the lamp 1001, which does not affect the good experience of the user.

[0078] S200, as Figure 4 As shown, in the case that the lamp 1001 flashes and emits light at the first frequency F1, the number N of times that the ambient light intensity is less than the first threshold M1 within at least one set time duration T0 is obtained; if the number N of times is greater than the second threshold M2, the lamp 1001 is controlled to enter the photosensitive mode; if the number N of times is less than or equal to the second threshold M2, no control signal is generated, and the lamp is turned off.

[0079] The set time duration T0 is the time period during which the lamp 1001 does not emit light in one flashing process of the lamp 1001 at the first frequency F1. The first threshold F1 is the critical value of the ambient light intensity for whether the lamp 1001 emits light or not. The light intensity of the first threshold F1 ranges from 5 LUX to 20 LUX. For example, the light intensity of the first threshold F1 is 5 LUX, 10 LUX or 20 LUX. For example, the light intensity of the first threshold F1 is 5 LUX.

[0080] For example, the first frequency F1 is 100 Hz, and one set time duration T0 is 0.01 second.

[0081] Since the lamp 1001 emits light under the driving of the PWM pulse modulation signal, the lamp 1001 turns on and off once in one cycle of the first frequency F1, and therefore, the processor 200 in the lamp 1001 can count within 0.01 second of turning off in the case that the human eye perceives that the lamp 1001 continuously emits light, which excludes the influence of the light emitting device 300 on the ambient light intensity of the photosensitive environment.

[0082] ​Exemplarily, the second threshold M2 is 3 times. In the case that the lamp 1001 emits light at a frequency of 100 Hz, the power-off period is 0.005 seconds; and the process that the light-sensitive sensing unit 100 detects the ambient light intensity once and transmits a signal to the processor 200 needs 15 microseconds, so that, in the condition that the human eye cannot perceive the flicker of the lamp 1001, the counting of 0.005 / 0.000015≈333 times of the lamp 1001 is performed, and in the multiple judgment processes, the number N is greater than the second threshold M2, which indicates that the current environment is in a dark state and no one is active.

[0083] After the above lamp 1001 enters the light-sensitive mode, the lamp 1001 emits light at a second frequency F2, wherein the second frequency F2 is greater than the first frequency F1. Exemplarily, the second frequency F2 is greater than 300 Hz. For example, the second frequency F2 is 310 Hz. In this way, in the case that the lamp 1001 emits light at a frequency of 310 Hz, the brightness of the light-emitting device 300 is close to the brightness under the normal voltage driving, which reduces the influence of the low working frequency on the low light-emitting brightness of the light-emitting device 300.

[0084] As shown in Figure 5 If the number N is less than or equal to the second threshold M2, no control signal is generated, and the lamp 1001 is controlled to enter the light-sensing mode; wherein the light-sensing mode includes the sensing mode and the light-sensitive mode. The above S200 includes the sensing mode S210 and the light-sensitive mode S220. After the human body sensing signal is collected in the sensing mode (S211 and S212), the light-sensitive mode S220 and S221 is entered.

[0085] S210, the light-sensing mode judges whether the current environment is the ambient light intensity less than the first threshold M1 and no human body sensing signal is acquired.

[0086] If yes, the lamp 1001 is controlled to be turned off.

[0087] If no, the sensing mode includes S211 and S212.

[0088] S211, the lamp 1001 is controlled to continue emitting light at the second frequency F2 for a first time length T1, and the sensing mode takes the first time length T1 as a period, and the human body sensing signal is collected once per period.

[0089] Exemplarily, the first time length T1 is 10 seconds to 20 seconds, for example, the first time length T1 is 10 seconds, 12 seconds or 20 seconds, which can be set according to actual needs. Collecting the human body sensing signal once per period includes sensing whether the current environment exists infrared ray within the first time length T1.

[0090] S212, if no human body sensing signal is collected (i.e. no infrared ray is sensed), the lamp 1001 is controlled to be turned off.

[0091] After the human body sensing signal is collected in the induction mode, the light sensitive mode S220 and S221 is entered. In this way, the lamp 1001 can determine that the current environment is that the ambient light intensity is less than the first threshold M1 and the human body sensing signal is not acquired,

[0092] S220, if the human body sensing signal is collected, the lamp 1001 is controlled to enter the light sensitive mode. The lamp 1001 continues to emit light at the second frequency F2 for the second time duration T2. Every second time duration T2 interval, the lamp 1001 emits light at the first frequency F1 for the third time duration T3. For example, the second time T2 is 10-20 seconds, for example, the second time T2 is 10 seconds, 15 seconds or 20 seconds, which can be set according to actual needs.

[0093] S221, in the third time duration T3, it is determined whether the number N is greater than the second threshold M2.

[0094] For example, the second time T2 is 15 seconds, and the third time T3 is 1 second. In the 1 second after every 15 seconds, it is determined whether N is greater than the second threshold M2. If so, the lamp 1001 continues to emit light at the second frequency F2 (i.e. 310 Hz), and the above processes of S200, S210, S211, S212, S220 and S221 are repeated.

[0095] If not, the lamp 1001 is controlled to turn off.

[0096] S230, in the case that the lamp 1001 is off, the ambient light intensity is acquired. If the ambient light intensity is greater than or equal to the first threshold M1, the lamp 1001 maintains the off state.

[0097] If the ambient light intensity is less than the first threshold M1, the lamp 1001 flashes at the first frequency F1 for the fourth time duration T4, and it is determined whether the number N is greater than the second threshold M2.

[0098] For example, after the lamp 1001 is powered on, the power-on state is maintained, and in the dark state without sensing infrared light, the off state is maintained, and in the light environment, the off state is maintained.

[0099] The lamp 1001 detects that the current environment is in a dark state, and the processor 200 controls the light emitting device 300 to flash at the first frequency F1 for the fourth time duration T4, for example, the fourth time duration T4 is 1 second. In 1 second, it is determined whether the number N is greater than the second threshold M2, and the above processes of S200, S210, S211, S212, S220 and S221 are repeated.
