[0002] Lighting devices with a moving object detection function have been widely applied in various buildings, such as parking lots, office buildings, factories, etc. The moving object detection function is usually realized by a microwave module (microwave sensor). However, the microwave module can be self-excited due to various reasons, which affects its accuracy. For example, the power supply line of the microwave module is susceptible to interference (such as ripple). For example, the power amplifier at the end of the circuit is susceptible to radio frequency signal interference. For example, an amplifier with high gain is susceptible to self-excitation. After the microwave module is self-excited, the microwave module internally outputs a high level to the detection pin of the control module of the lighting device, which is the same as the trigger signal generated when the microwave module detects a moving object. The above condition can cause the lighting device to suddenly turn on. SUMMARY

[0006] In an embodiment, when the first comparison result shows that the number of times is greater than the first threshold value or the second comparison result shows that the sum is greater than the second threshold value, the control module generates a detection result indicating an abnormal state.

DETAILED DESCRIPTION

In order to make the drawings clear and convenient for description, the components in the drawings may be exaggerated or reduced in size and proportion.

For ease of understanding, the same components in the following embodiments are described with the same symbols.
[0030] Referring to Figure 1 , which is a block diagram of the circuit of the lighting device with microwave module self-checking function of the first embodiment of the present application. As shown in the figure, the lighting device 1 includes a control module 11, a microwave module 12, a light emitting module 13 and a communication module 14.
[0031] The microwave module 12 is connected to the control module 11. The control module 11 is connected to the microwave module 12 by detecting the foot position. In an embodiment, the microwave module 12 can be one of various existing microwave sensors. In another embodiment, the microwave module 12 can be one of various circuits with microwave sensing function. In an embodiment, the control module 11 can be a microcontroller (MCU). In another embodiment, the control module 11 can be a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other similar components.
[0032] The light emitting module 13 is connected to the control module 11. In an embodiment, the light emitting module 13 can be a light emitting diode. In another embodiment, the light emitting module 13 can also be a light emitting diode array, a light bulb, a fluorescent lamp, or other existing light sources.
[0033] The communication module 14 is connected to the control module 11. In an embodiment, the communication module 14 can be a Bluetooth module. In another embodiment, the communication module 14 can also be a WiFi module, a ZigBee module, or other similar components.
[0034] When the microwave module 12 detects a moving object, the microwave module 12 generates a high level signal (trigger signal) and transmits it to the control module 11. Then, the control module 11 turns on the light emitting module 13 and simultaneously transmits a start signal to other lighting devices 1 through the communication module 14 to start other lighting devices 1. When the microwave module 12 generates a self-excitation, the microwave module 12 also generates a high level signal (same as the trigger signal) and transmits it to the control module 11.
[0035] The control module 11 performs a self-check mode. In the self-check mode, the control module 11 adjusts the light emitting module 13 from the current brightness to the test brightness within a predetermined time interval. The control module 11 turns off the communication module 14 to keep the communication module 14 in the off state within the predetermined time interval. The above-mentioned predetermined time interval can be adjusted according to actual needs. For example, the above-mentioned predetermined time interval can be half an hour, 1 hour, or 2 hours, but is not limited thereto. The above-mentioned test brightness can be the maximum brightness of the light emitting module 13, but is not limited thereto. When the brightness of the light emitting module 13 reaches the maximum, the noise of the lighting device 1 is the largest, so the microwave module 12 is prone to self-excitation.
[0036] Then, in the self-checking mode, the control module 11 detects the number of times the microwave module 12 generates the trigger signal within a preset time interval and calculates the sum of the durations of each trigger signal. Then, the control module 11 generates a detection result according to the number of times and the sum. Wherein, the control module 11 compares the number of times with a first threshold value to generate a first comparison result, and compares the sum with a second threshold value to generate a second comparison result. Then, the control module 11 generates the detection result according to the first comparison result and the second comparison result. When the first comparison result shows that the number of times is greater than the first threshold value or the second comparison result shows that the sum is greater than the second threshold value, the control module 11 generates the detection result indicating the abnormal state and transmits to the electronic device of the user. Then, the control module 11 turns off the control module 11, the microwave module 12, the light-emitting module 13 and the communication module 14. At this time, the lighting device 1 does not participate in the operation of the lighting system, and the user can take necessary measures (such as repairing the lighting device 1). In this embodiment, the first threshold value can be 1, and the second threshold value can be 60 seconds. In another embodiment, the first threshold value can be 2, and the second threshold value can be 120 seconds. The first threshold value and the second threshold value can be adjusted according to actual needs.
[0037] As can be seen from the above, the microwave module self-checking mechanism can be directly executed by the control module 11 of the lighting device 1, without the need for manual detection. Therefore, the microwave module 12 self-checking mechanism can reduce the labor cost of maintaining the lighting device 1, so as to meet the needs of practical applications.
[0038] In addition, in this embodiment, the lighting device 1 has a special microwave module self-checking mechanism, which can effectively prevent the lighting device 1 from being abnormally turned on due to the abnormality of the microwave module 12. Therefore, the microwave module self-checking mechanism can effectively reduce the energy consumption of the lighting device 1, so that the lighting device 1 can be more energy-saving. Therefore, the lighting device 1 can meet the requirements of environmental protection, and can meet the trend of future development.
[0039] In addition, in this embodiment, the lighting device 1 has a special microwave module self-checking mechanism, and the microwave module self-checking mechanism can be directly executed by the control module 11 of the lighting device 1, without the need for manual detection or additional circuit components. Therefore, the microwave module self-checking mechanism does not increase the manufacturing cost of the lighting device 1, and can achieve the desired effect to meet the needs of different applications.
[0040] Of course, this embodiment is only used for illustration and does not limit the scope of the present application. Equivalent modifications or changes made to the lighting device with microwave module self-checking function according to this embodiment should still be included in the patent scope of the present application.

[0042] The microwave module 12 is connected with the control module 11. The control module 11 is connected with the microwave module 12 through a detection pin. The light emitting module 13 is connected with the control module 11. The communication module 14 is connected with the control module 11.
[0043] Different from the foregoing embodiment, in the present embodiment, the lighting device 1 further comprises a real time clock (RTC) module 15. The user can adjust the setting of the real time clock module 15 to change the running time of the self-checking mode. Therefore, the user can set the lighting device 1 to perform self-checking at midnight or other appropriate time to ensure that the lighting system can operate normally.
[0044] The user can directly adjust the setting of the real time clock module 15 to change the running time of the self-checking mode through an application program of an electronic device (such as a smart phone, a tablet computer, a notebook computer, etc.), without the assistance of technical personnel. Therefore, the use of the lighting device 1 can be more convenient, and can better meet the needs of different applications.
