Use the utility model discloses a during microwave response lamp 1, can install the lamp body 10 of microwave response lamp 1 in the position that needs, like corridor, lavatory, bedroom, kitchen etc. the response piece 20 correspondence that will be equipped with microwave sensor 201 is installed in positions such as the gate in corridor, lavatory, bedroom, kitchen to adjust the direction orientation detection area of microwave sensor 201 transmission electromagnetic wave, can arrange lamp body 10 and response piece 20 according to actual demand separately in a flexible way. The lamp body 10 and the sensing element 20 are connected by wire to transmit signals, but may also be connected wirelessly. In addition, the lamp housing and the induction housing may be square, conical, truncated pyramid or hollow bodies of other shapes, and only the hollow space thereof is required to respectively satisfy the requirements for installing the controller 101, the lighting module 102, the microwave sensor 201 and the processing module 202, and the appearance is elegant. When a user moves from outside the detection area to inside the detection area or moves inside the detection area, the microwave sensor 201 can detect a motion signal characteristic with relatively weak amplitude and frequency, and when the user performs a motion with a large amplitude in the detection area, such as swinging a hand, swinging, etc., the signal characteristic detected by the microwave sensor 201 changes from weak to strong.

When the microwave sensor 201 detects that the detection area has the characteristic of the motion signal, the amplitude of the motion signal is weaker than the amplitude of the comparison signal, and the frequency of the motion signal is lower than the frequency of the comparison signal, the comparison result obtained by the processor 2025 is the first comparison result, and the processor outputs the first control signal, and adjusts the state of the illumination module 102 from the off state to the first illumination state through the controller 101. In this embodiment, the lighting module 102 has an LED lamp, which may be an incandescent lamp or other types of lamps, and the LED lamp may be disposed on the outer surface of the lamp housing or may be flexibly disposed outside the lamp housing through a connecting wire. The first illumination state of the illumination module 102 is a backlight illumination state, and at this time, light emitted by the LED lamp of the illumination module 102 is low-brightness light, so as to avoid stimulating the vision of the user and improve the comfort level of the user.

Furthermore, when the amplitude of the motion signal feature detected by the microwave sensor 201 changes from weak to strong, and is finally stronger than or equal to the amplitude of the contrast signal, the frequency is higher than or equal to the frequency of the contrast signal, and the motion signal feature is close to the microwave sensor 201, that is, the user performs a great movement such as waving or swaying while approaching the sensing member 20, and the amplitude of the action is greater than or equal to the amplitude of the comparison signal, and the frequency is greater than or equal to the frequency of the comparison signal, the comparison result obtained by the processor 2025 will be the second comparison result, which outputs a second control signal to adjust the state of the illumination module 102 from the first illumination state to the second illumination state by the controller 101, which, in the present embodiment, the second illumination state is a high-intensity illumination state, in which the light emitted from the LED lamp of the illumination module 102 is a light with higher brightness, so as to provide sufficient brightness for the user.

Further, when the motion signal characteristic detected by the microwave sensor 201 changes from weak to strong, and is finally stronger than or equal to the amplitude of the contrast signal, and the frequency is higher than or equal to the frequency of the contrast signal, and the motion signal characteristic is far from the microwave sensor 201, that is, when the user moves far from the sensing element 20 and makes a motion with a larger amplitude, such as waving or swinging, and the amplitude of the motion is larger than or equal to the amplitude of the contrast signal, and the frequency is higher than or equal to the frequency of the contrast signal, the comparison result obtained by the processor 2025 is a third comparison result, which outputs a third control signal, and the state of the illumination module 102 is adjusted from the second illumination state to the third illumination state by the controller 101. In this embodiment, the third illumination state is a backlight illumination state, in which the light emitted by the LED lamp of the illumination module 102 is low-brightness light.

Furthermore, when the motion signal characteristic detected by the microwave sensor 201 changes from the present state to the present state, i.e. the user moves from the inside of the detection area to the outside of the detection area, and the motion signal characteristic does not exist in the detection area, the processor 2025 outputs a fourth control signal to the controller 101, and the controller 101 controls the lighting module 102 according to the fourth control signal, so that the lighting state of the lighting module 102 is switched from the third lighting state to the off state, i.e. the LED lamp is turned off.

However, if the illumination state of the illumination module 102 is the backlight illumination state, the feature of the action signal continuously detected by the microwave sensor 201 does not change, or the change amplitude and the frequency do not satisfy the condition of triggering the second illumination state of the illumination module 102, and the illumination module 102 maintains the backlight illumination state, so that the lighting module 102 can avoid the false triggering of the strong illumination state and save the electric energy. Similarly, if the illumination state of the illumination module 102 is the high-intensity illumination state, the feature of the action signal continuously detected by the microwave sensor 201 does not change, or the change amplitude and the frequency do not satisfy the condition of triggering the third illumination state of the illumination module 102, and the illumination module 102 maintains the high-intensity illumination state, so that the third illumination state or the off state of the illumination module 102 can be prevented from being triggered by mistake, and the illumination state of the microwave induction lamp 1 needs to be triggered and adjusted again through the action feature. Therefore, the switching frequency of the LED lamp can be reduced, the service life of the LED lamp is prolonged, and the LED lamp is more in line with the concept of energy conservation and environmental protection.

Furthermore, the microwave induction lamp of the present invention further includes a power supply module (not shown in the figure), which is electrically connected to the microwave sensor 201, the processing module 202, the controller 101 and the lighting module 102 respectively to provide the required working current. The power supply module may be a recyclable power supply, a disposable power supply, or an external power supply, and when the power supply module is connected to the external power supply, the power supply module has an adaptive transformer for transforming the external current, so that the input current is suitable for the microwave sensor 201, the processing module 202, the controller 101, and the lighting module 102.

To sum up, the utility model provides a pair of microwave induction lamp, it passes through first Doppler signal of microwave sensor output and second Doppler signal, and processing module is according to first Doppler signal and second Doppler signal output control signal, controller received control signal to illumination state according to control signal control lighting module, on the one hand, the lamp body can separately arrange according to actual demand with the response piece, satisfies different user demands, on the other hand, the utility model discloses a different control signal of microwave induction lamp corresponds different illumination state, can not only satisfy the illumination demand of people's diversification day by day, improves user's use comfort, can also avoid the frequent switching of state that the spurious triggering leads to the lamp, so, the utility model discloses a microwave induction lamp has longer life and better energy-conserving performance.
