It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present utility model described herein can be implemented in an order different from those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0036] The embodiment of the present utility model provides an induction lighting device. The induction lighting device is applicable to indoor and outdoor lighting, lights up when an object passes through the induction area, and can communicate with nearby induction lighting devices. The induction module of the induction lighting device in this embodiment can filter the communication signals during the communication of the communication module, which is beneficial to avoiding the mis-triggering of the induction lighting device. Figure 1 is a schematic diagram of an induction lighting device provided by an embodiment of the present utility model. Refer to Figure 1 , the induction lighting device includes: an induction module 110, a control module 120, a communication module 130, and a lighting module 140.
[0037] The lighting module 140 is used for lighting; the communication module 130 is used to generate communication signals and communicate with nearby inductive lighting devices; the induction module 110 includes an antenna unit 111, a filtering and amplifying unit 112, and a radar unit 113; the antenna unit 111 is respectively connected to the filtering and amplifying unit 112 and the radar unit 113; the filtering and amplifying unit 112 is also connected to the radar unit 113; the antenna unit 111 is used to transmit electromagnetic waves and receive the echoes of electromagnetic waves; the filtering and amplifying unit 112 is used to filter the communication signals in the echoes and amplify the filtered echoes to generate radar signals; the radar unit 113 is used to determine whether an object has passed according to the radar signals, and generate induction signals when an object has passed; the control module 120 is respectively connected to the radar unit 113, the lighting module 140, and the communication module 130; the control module 120 is used to control the lighting module 140 to turn on for a preset time according to the induction signals, and control the communication module 130 to broadcast the induction signals.
[0038] Specifically, the radar unit 113 outputs a continuous wave signal or a pulse signal. The antenna unit 111 acquires the continuous wave signal or the pulse signal and converts the continuous wave signal or the pulse signal into electromagnetic waves. Among them, the continuous wave signal refers to an electrical signal that is continuous in time; the pulse signal is an electrical signal with a specific pulse width and pulse repetition period. The antenna unit 111 transmits the electromagnetic waves to a certain range, and this range is the induction range of the induction module 110. During the propagation of the electromagnetic waves, when the electromagnetic waves encounter an obstacle, part of the electromagnetic waves will be reflected back to the antenna unit 111 and thus be captured and received by the antenna unit 111. The electromagnetic waves captured and received by the antenna unit 111 are the echoes. Since the communication module 130 communicates with nearby inductive lighting devices, the communication signals generated by the communication module 130 are also electromagnetic waves. Therefore, the echoes received by the antenna unit 111 contain the reflected electromagnetic waves and the electromagnetic waves (communication signals) generated by the communication module 130. The filtering and amplifying unit 112 acquires the echoes, filters out the electromagnetic waves (communication signals) generated by the communication module 130 in the echoes, and amplifies the filtered echoes. Among them, the filtered and amplified echoes are the radar signals.
[0039] The radar unit 113 acquires radar signals and determines whether there is an object entering the sensing range of the sensing module 110 based on the radar signals. When there is no object entering the sensing range of the sensing module 110, the radar signals acquired by the radar unit 113 are relatively weak and stable. When there is an object entering the sensing range of the sensing module 110, due to the reflection of electromagnetic waves by the object, the radar signals acquired by the radar unit 113 are relatively strong. Exemplarily, the radar unit 113 can determine whether there is an object entering the sensing range by comparing the radar signals with a preset signal. The preset signal is the radar signal when there is no object entering the sensing range preset in advance. When the sensing module 110 is in different environments, the preset signal is also different. In practical applications, the preset signal can be set according to the environment where the sensing module 110 is located. This embodiment does not limit this. The radar unit 113 generates a sensing signal when it determines that an object has entered the sensing range.
[0040] The control module 120 acquires the sensing signal and controls the lighting module 140 to turn on for lighting according to the sensing signal. After a preset time, the control module 120 controls the lighting module 140 to turn off. In addition, after acquiring the sensing signal, the control module 120 also controls the communication module 130 to broadcast the acquired sensing signal. The preset time is the preset turn-on time of the lighting module 140. In practical applications, the preset time can be set according to actual requirements. This embodiment does not limit this. It should be noted that the sensing signal acquired by the control module 120 can be the sensing signal generated by the radar unit 113, or the sensing signal broadcast by a nearby inductive lighting device received by the communication module 130 when the communication module 130 communicates with the nearby inductive lighting device.
[0041] In the embodiment of the present utility model, the antenna unit 111 emits electromagnetic waves and receives echoes. The filtering and amplifying unit 112 filters out the communication signals contained in the echoes and amplifies the filtered echoes to generate radar signals. The radar unit 113 determines whether there is an object entering according to the radar signals and generates a sensing signal when there is an object entering. The control module 120 acquires the sensing signal. The control module 120 controls the lighting module 140 to turn on within a preset time according to the sensing signal and controls the communication module 130 to broadcast the sensing signal. The filtering and amplifying unit 112 of the embodiment of the present utility model filters out the communication signals contained in the echoes, which is beneficial to improving the accuracy of object sensing of the lighting device and avoiding mis-triggering of the lighting device.
[0042] Figure 2 is a schematic diagram of another inductive lighting device provided by the embodiment of the present utility model. On the basis of the above embodiment, optionally, referring to Figure 2 , the filtering and amplifying unit 112 includes: a filter 1121 and an amplifier 1122.
[0043] The input end of the filter 1121 is connected to the antenna unit 111; the output end of the filter 1121 is connected to the input end of the amplifier 1122; the output end of the amplifier 1122 is connected to the radar unit 113; the filter 1121 is used to filter the communication signal in the echo; the amplifier 1122 is used to amplify the filtered echo to generate a sensing signal.
[0044] Specifically, the filter 1121 obtains the echo captured and received by the antenna unit 111, and filters out the communication signal generated by the communication module 130 contained in the echo. The amplifier 1122 obtains the echo filtered by the filter 1121, and amplifies the filtered echo. When applied, the filtering frequency band of the filter 1121 should be staggered with the frequency band of the electromagnetic wave generated by the antenna unit 111 to avoid the influence of the filter 1121 on the echo. For example, the filtering frequency band of the filter is 0-4G and 7G-12G, and the frequency band of the electromagnetic wave generated by the antenna unit 111 is 5.725G-5.825G. In this embodiment, the communication signal of the communication module 130 is filtered by the filter 1121, and the filtered echo is amplified by the amplifier 1122, which is conducive to reducing the proportion of interference signals in the echo and improving the signal-to-noise ratio of the radar signal.
[0045] Based on the above embodiments, optionally, the filter 1121 may be a bandpass filter, and the amplifier may be a low noise amplifier. It should be noted that in practical applications, the type or model of the filter 1121 and the amplifier 1122 may be selected according to actual needs, and this embodiment does not limit this.
[0046] Specifically, a bandpass filter is a signal processing device that can filter out signals outside a specified frequency range while retaining signals within the range. The bandpass filter uses a specific circuit structure to set a passband (i.e., a frequency range allowed to pass) and two cutoff frequencies (i.e., a frequency range not allowed to pass) in the filter to achieve the screening and processing of input signals. Different bandpass filters have different circuit structures. In practical applications, the circuit structure of the bandpass filter can be set according to actual needs, and this embodiment does not limit this.
[0047] A low noise amplifier (LNA) is an electronic amplifier that can amplify a weak received signal. During amplification, the noise generated by the low noise amplifier is small, and its influence on the signal is small.
[0048] Figure 3 is a schematic diagram of another induction lighting device provided by an embodiment of the utility model. Based on the above embodiment, optionally, referring to Figure 3, the antenna unit 111 includes: a transmitting antenna 1111 and a receiving antenna 1112.
[0049] The transmitting antenna 1111 is connected to the radar unit 131; the receiving antenna 1112 is connected to the filtering and amplifying unit 112; the transmitting antenna 1111 is used to transmit electromagnetic waves; the receiving antenna 1112 is used to receive the echo of the electromagnetic waves.
[0050] Specifically, the transmitting antenna 1111 converts the continuous wave signal or pulse signal output by the radar unit 131 into electromagnetic waves and transmits the electromagnetic waves within a certain range. The electromagnetic wave transmission range of the transmitting antenna 1111 is the sensing range of the sensing module 110. The receiving antenna 1112 captures and receives the echo of the electromagnetic waves transmitted by the transmitting antenna 1111. In actual applications, the transmitting antenna 1111 and the receiving antenna 1112 can also be classified and set, or can be integrated into one body, and this embodiment does not limit this.
[0051] Based on the above embodiments, optionally, the communication module 130 includes at least one of a Bluetooth chip or a wireless network communication chip. Specifically, the communication method by which the communication module 130 communicates with the nearby inductive lighting device is Bluetooth communication and / or Wi-Fi (Wireless Fidelity) communication.
[0052] Based on the above embodiments, optionally, the lighting module 140 includes at least one lamp. Exemplarily, the lamp in the lighting module 140 can be an LED (Light Emitting Diode) lamp, can also be an incandescent lamp, or can also be a fluorescent lamp, and this embodiment does not limit this.
[0053] Figure 4 is a schematic diagram of another inductive lighting device provided by an embodiment of the present invention. Based on the above embodiments, optionally, referring to Figure 4 , the inductive lighting device further includes: an illuminance detection module 150.
[0054] The illuminance detection block 150 is connected to the control module 120; the illuminance detection module 150 is used to detect the light intensity of the surrounding environment and generate a turn-off signal when the light intensity is greater than a preset light intensity; the control module 120 is further used to control the lighting module 140 to turn off according to the turn-off signal.
[0055] Specifically, the illuminance detection block 150 detects the light intensity of the environment where the lighting module 140 is located, and compares the detected light intensity with a preset light intensity. The illuminance detection block 150 generates a turn-off signal when the light intensity of the environment where the lighting module 140 is located is greater than the preset light intensity. The control module 120 obtains the turn-off signal and controls the lighting module 140 to turn off according to the turn-off signal. Exemplarily, when the light intensity of the environment where the lighting module 140 is located is greater than the preset light intensity, a turn-off signal is continuously generated. When the control module 120 obtains the turn-off signal, it always controls the lighting module 140 to turn off. During this period, if the control module 120 obtains an induction signal, the control module 120 also controls the lighting module 140 to turn off. It should be noted that the preset light intensity is the lowest light intensity required for the lighting module 140 to turn on, which can be set according to actual needs in practical applications, and this embodiment does not limit this.
[0056] An embodiment of the present invention also provides an induction lighting system. Figure 5 is a schematic diagram of an induction lighting system provided by an embodiment of the present invention. Refer to Figure 5 , the induction lighting system 1000 includes a gateway 200 and at least two or more induction lighting devices 100 provided by any of the above embodiments.
[0057] The gateway 200 is communicatively connected to the communication modules in each induction lighting device 100; the gateway 200 is used for the interaction between the user and each induction lighting device 100.
[0058] Specifically, the user can communicate with the gateway 200 through a mobile terminal and set the induction lighting device 100. For example, set the preset light intensity or preset time. Among them, the induction lighting system 1000 provided by this embodiment has the beneficial effects of the induction lighting device 100 provided by any of the above embodiments, which will not be elaborated here.

For example, the steps described in the present invention can be executed in parallel, sequentially, or in a different order, as long as the desired results of the technical solution of the present invention can be achieved, and this is not limited herein.
