Adopt the technical scheme of the utility model afterwards, can avoid the LED lamp to be lighted when light is bright on every side to play energy-conserving effect to a certain extent. However, the on and off of the microwave induction lamp are determined according to the light intensity threshold, that is, the light intensity value fed back by the photosensitive sensor is compared with the light intensity threshold, and when the light intensity value is smaller than the light intensity threshold, the control module controls the LED lamp driving module to light the LED lamp; on the contrary, if the light intensity value is larger than the light intensity threshold value, the control module controls the LED lamp driving module to turn off the LED lamp.

However, under the condition of very weak ambient light or less people flow in the next midnight, if the induction lamp still keeps a normally-on state, the electric energy loss is easily caused; if the induction lamp is directly turned off, the lighting and indicating functions cannot be achieved, and therefore certain improvement space exists.

The microwave induction lamp disclosed in this embodiment, as shown in fig. 1, includes a microwave induction module 1, a light induction module 2, a control module 3, a main driving module 4, and an auxiliary driving module 5. The microwave sensing module 1 is preferably a microwave sensor, also called microwave radar, which is an instrument manufactured by using the doppler principle of electromagnetic waves and can sense a moving object in a monitoring area so as to judge whether a human body approaches; the light sensing module 2 is preferably a photosensitive sensor, which can effectively monitor the light intensity change around the sensing lamp and send the measured light intensity value to the control module 3; the control module 3 is a chip with data processing capability, including but not limited to a single chip microcomputer, a CPU, an MCU, an ARM, etc. The main driving module 4 and the auxiliary driving module 5 are preferably driving circuits of LED lamps, and the driving circuits can convert power parameters of an external power supply into power parameters meeting the operation requirements of the main lamp set 6 and the auxiliary lamp set 7.

Furthermore, as shown in fig. 2, 3 and 4, the microwave sensing module 1 and the light sensing module 2 are both in communication connection with the control module 3, and the main driving module 4 and the auxiliary driving module 5 are both coupled and controlled by the control module 3; a main lamp group 6 is coupled to the main drive module 4, and a sub lamp group 7 is coupled to the sub drive module 5. More specifically, main banks 6 are equipped with a plurality ofly, and every main banks 6 of group forms in order to form main lamp ring 9 by the equidistant circumference arrangement of many LED lamp pearls 8, and a plurality of main lamp rings 9 are concentric setting and outwards expand in proper order, and the distance between the adjacent main lamp ring 9 keeps unanimous. More specifically, vice banks 7 are equipped with a plurality ofly, and every vice banks 7 of group are formed in order to form the vice lantern ring 10 with the concentric setting of main lantern ring 9 by the equidistant circumference range of many LED lamp pearls 8, and a plurality of vice lantern rings 10 are concentric setting and outwards expand in proper order, and the distance between the adjacent vice lantern ring 10 keeps unanimous. And a plurality of auxiliary lamp rings 10 are sequentially arranged in the space formed by the adjacent main lamp rings 9. All the main lamp rings 9 and the auxiliary lamp rings 10 can be arranged concentrically, and are expanded outwards in the sequence of "the main lamp ring 9", "the auxiliary lamp ring 10", "the main lamp ring 9" and "the auxiliary lamp ring 10" … …, and the distance between the main lamp ring 9 and the auxiliary lamp ring 10 is kept consistent. Meanwhile, the number of the LED lamp beads 8 in each main lamp group 6 is consistent with that of the LED lamp beads 8 in each auxiliary lamp group 7. And the LED lamp beads 8 in each auxiliary lamp group 7 are sequentially positioned in the middle positions of two adjacent LED lamp beads 8 in the adjacent main lamp group 6. The LED lamp beads 8 are all mounted on the aluminum substrate, and the electrical connection between the LED lamp beads 8 is common knowledge in the art and is not described herein.

In this embodiment, the microwave sensing module 1 is configured to detect an approaching or a departing of a moving object to output a corresponding movement detection signal to the control module 3, and the light sensing module 2 is configured to monitor a light intensity value of an environment around the microwave sensing lamp and output the light intensity value to the control module 3; a first light intensity threshold and a second light intensity threshold lower than the first light intensity threshold are preset in the control module 3. The first light intensity threshold value corresponds to the light intensity of the sensing lamp with weak ambient light, and the second light intensity threshold value corresponds to the light intensity of the sensing lamp with very dark ambient light.

When microwave response module 1 detects that moving object is close to the microwave response lamp, if the light intensity value that light response module 2 monitored is higher than first light intensity threshold value, it is bright to explain the ambient light around the response lamp, and control module 3 controls main drive module 4 and vice drive module 5 to close main banks 6 and vice banks 7 respectively this moment, avoids extravagant electric energy. If the light intensity value is between the first light intensity threshold and the second light intensity threshold, which indicates that the ambient light around the induction lamp is weak, the main driving module 4 and the auxiliary driving module 5 respectively start the main lamp set 6 and the auxiliary lamp set 7 at this time, so that the main lamp set 6 and the auxiliary lamp set 7 work simultaneously, thereby providing high-intensity light for the ambient environment. If light intensity value is less than second light intensity threshold value, it is very dark to explain the light around the response lamp, and main drive module 4 closes main banks 6 this moment, and vice drive module 5 starts vice banks 7 simultaneously to make vice banks 7 work alone, both saved partial electric energy, can guarantee the illuminating effect of response lamp again.

On the contrary, when the microwave sensing module 1 cannot detect the moving object, it is indicated that no person is near the sensing lamp, the control module 3 controls the main driving module 4 and the auxiliary driving module 5 to respectively turn off the main lamp group 6 and the auxiliary lamp group 7, thereby avoiding the waste of electric energy.

Furthermore, the control module 3 includes a timing unit 11, the timing unit 11 is preferably a timer, and the timing unit 11 is preset with a reference time length. In the case that the light intensity value is lower than the second light intensity threshold value, that is, the ambient light intensity around the sensing lamp is very weak, the control module 3 only starts the sub-lamp set 7 at this time. In order to prolong the service life of the auxiliary lamp group 7, after the auxiliary driving module 5 starts the auxiliary lamp group 7, the timing unit 11 starts timing, if the timing period exceeds the reference time length, the control module 3 controls the auxiliary driving module 5 to close the auxiliary lamp group 7, meanwhile, the main driving module 4 starts the main lamp group 6, and the timing unit 11 stops timing. After the main driving module 4 starts the main lamp group 6, the timing unit 11 starts timing, if the timing period exceeds the reference time length, the control module 3 controls the main driving module 4 to close the main lamp group 6, and simultaneously controls the auxiliary driving module 5 to start the auxiliary lamp group 7, and the timing unit 11 stops timing. By circulating the above steps, the main lamp group 6 and the auxiliary lamp group 7 alternately operate, thereby reducing the working intensity of the single lamp group and prolonging the service life.

The control module 3 further includes a delay unit 12, and a delay duration is preset in the delay unit 12, and the delay duration is preferably 2 seconds. When the timing period of the timing unit 11 exceeds the reference time length, the control module 3 controls the main driving module 4 and the auxiliary driving module 5 to respectively start the main lamp group 6 and the auxiliary lamp group 7, and meanwhile, the delay unit 12 enters a delay state; when the delay period exceeds the delay time, the control module 3 will control the main driving module 4 or the auxiliary driving module 5 to cut off the main lamp set 6 or the auxiliary lamp set 7. That is, in the process of switching the main lamp group 6 to the auxiliary lamp group 7, or switching the auxiliary lamp group 7 to the main lamp group 6, the two lamp groups are kept in a full-on state firstly to maintain the illumination effect of the induction lamp, and after the time delay, the control module 3 switches the induction lamp to the next lamp group again, so that the induction lamp is prevented from being extinguished in the process of switching the lamp groups.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
