Description

Technical Field

[0001] This utility model relates to lighting devices, and more particularly to sensor-activated lamps. Background Technology

[0002] Microwave induction lamps have been widely used due to their superior performance, and their market potential is enormous. However, current microwave induction lamps on the market are relatively simple in structure, lacking novelty and creativity. Replacing the light source is troublesome, installation is difficult, and many microwave lamps have poor anti-interference capabilities, sometimes detecting signals in places where they are not needed, causing considerable inconvenience to users. Utility Model Content

[0003] The main technical problem to be solved by this utility model is to provide a microwave sensing module that can shield the microwave sensing signal emitted by the microwave sensing module to the rear and can also increase the sensing angle.

[0004] To address the aforementioned technical problems, this utility model provides a microwave sensing module, comprising: a microwave sensing module, an insulating layer, and a metal shield; the microwave sensing module has an arc-shaped curved surface, the insulating layer is disposed on the outer side of the arc-shaped curved surface, and the metal shield is disposed on the side of the insulating layer facing away from the microwave sensing module, so as to shield the microwave sensing signal emitted by the microwave sensing module toward the side closer to the metal shield.

[0005] In a preferred embodiment, the antenna of the microwave induction module is disposed on both sides of the arc-shaped curved surface.

[0006] In a preferred embodiment, the microwave emission angle of the microwave sensing module is 180-270°.

[0007] In a preferred embodiment, the thickness of the metal shield is greater than the radius of the curved surface, so that the metal shield bulges outward relative to the curved surface.

[0008] This utility model also provides a sensor lamp equipped with the microwave sensing module described above.

[0009] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0010] This invention provides a microwave sensing module. By arranging the microwave sensing module in an arc shape, it creates a natural cavity, providing additional installation space for the metal shield. This allows for an increase in the thickness of the metal shield, which in turn attenuates the microwave signal emitted by the module, reducing the probability of false triggering behind the light fixture. Furthermore, the arc shape also increases the sensing angle of the microwave sensing module, expanding the effective sensing area in front of it. Attached Figure Description

[0014] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0015] refer to Figure 1-3 This embodiment provides a sensor lamp that achieves sensing through microwave induction. For this purpose, it is equipped with a microwave induction module, which includes: a microwave induction module 1, an insulating layer 2, and a metal shield 3. The microwave induction module 1 has an arc-shaped curved surface, the insulating layer 2 is disposed on the outer side of the arc-shaped curved surface, and the metal shield 3 is disposed on the side of the insulating layer 2 facing away from the microwave induction module 1 to shield the microwave induction signal emitted by the microwave induction module 1 towards the side near the metal shield 3.

[0016] In this embodiment, to increase the sensing angle of the microwave sensing module 1, the antenna of the microwave sensing module 1 is disposed on both sides of the arc-shaped curved surface. This allows the microwave emission angle of the microwave sensing module 1 to be 180-270°.

[0017] Furthermore, in this embodiment, the thickness of the metal shield 3 is greater than the radius of the curved surface, so that the metal shield 3 bulges outward relative to the curved surface.

[0018] Therefore, by designing the microwave sensing module 1 in an arc shape, the aforementioned microwave sensing module 1 possesses a natural cavity 11. This provides additional installation space for the metal shield 3, allowing for an increase in the thickness of the metal shield 3. This attenuates the microwave sensing signal emitted by the microwave sensing module 1 to the rear, thereby reducing the probability of false triggering behind the lamp. Furthermore, designing the microwave sensing module 1 in an arc shape also increases its sensing angle, expanding the effective sensing area in front of the microwave sensing module 1.

[0019] In this embodiment, the microwave sensing module 1 is an arc shape with no sharp edges. As a simple replacement, the microwave sensing module 1 can also be set as an arc surface with sharp edges formed by splicing at least two surfaces. The number of surfaces can be two, three or more.

[0020] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
