Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of microwave induction lamps, in particular to a microwave induction LED filament lamp. Background Art
[0002] The working principle of microwave induction lamp is mainly to transmit electromagnetic waves through a planar antenna. When a moving object enters the electromagnetic wave environment, the waveform is reflected back. After the planar antenna receives the feedback waveform, the subsequent circuit detects the trigger signal and works. This microwave induction technology uses the Doppler effect principle of electromagnetic waves. If the obstacle moves toward or away from the wave source, the reflected wave will change. Microwave induction knows that a moving object is approaching or moving away through the change of the reflected wave.
[0003] The structure of the existing microwave induction LED filament lamp is as follows Figure 1 As shown, the microwave sensing module 3 is arranged in the plastic part 2, and the plastic part 2 is fixed between the bulb shell 4 and the lamp holder 1. The plastic part 2 will increase the cost, and the appearance is not simple enough, which affects the customer's willingness to buy. In addition, since there is an exhaust pipe at the tail of the bulb shell 4 and a horn tube sintered with the bulb shell 4, the exhaust pipe may affect the installation of the microwave sensing module 3 when it is too long. Moreover, the signals sent and received by the microwave sensing module need to penetrate multiple layers of glass. The signal strength will be significantly attenuated due to the interference of the glass, resulting in a shortened sensing distance, a reduced sensing angle, and a more serious self-excitation. The sensing ability of the bulb is not consistent, which affects the user experience. Utility Model Content
[0004] The purpose of the utility model is to overcome the deficiencies in the above-mentioned background technology and provide a microwave induction LED filament lamp, which can effectively reduce the interference to the microwave induction module, improve the induction ability and reduce the production cost.
[0005] The technical solution adopted by the utility model is as follows:
[0006] A microwave induction LED filament lamp comprises a filament lamp body and a microwave induction module. The microwave induction module is arranged in a bulb shell of the filament lamp body, and a connection terminal of the microwave induction module is connected to a driving module of the filament lamp body through a wire.
[0007] In a further solution, the microwave sensing module is arranged at the overhanging end of the core column of the filament lamp body, and the planar antenna on the front side of the microwave sensing module is arranged away from the overhanging end of the core column.
[0008] In a further solution, a through hole is provided on the microwave induction module, and the through hole is used to sleeve on the core column of the filament lamp body.
[0009] In a further embodiment, at least one edge of the microwave induction module is provided with a bayonet, and the bayonet is used to tightly clamp the outer wall of the core column of the filament lamp body.
[0010] In a further embodiment, the microwave induction module is arranged on the side of the core column of the filament lamp body, and the planar antenna on the front of the microwave induction module is arranged away from the core column.
[0011] In a further embodiment, the planar antenna is arranged parallel to the core column, or a certain angle is formed between the planar antenna and the core column.
[0012] In a further embodiment, the microwave induction module is adhesively bonded to the core column of the filament lamp body with glue.
[0013] In a further embodiment, the microwave induction module is fixedly connected to the core column of the filament lamp body through an intermediate connecting member.
[0014] In a further embodiment, the intermediate connecting member has a first connecting portion and a second connecting portion; the first connecting portion is an O-shaped or C-shaped or U-shaped structure and is connected to the core column; the second connecting portion is a buckle structure and is connected to the microwave induction module.
[0015] In a further embodiment, the intermediate connecting member is a bracket bent from a metal wire, one section of the metal wire is tightly fastened to the core column, and the metal wire is fixedly connected to the microwave induction module.
[0016] The beneficial effects of the present utility model are as follows: The microwave induction module of the present utility model is arranged inside the bulb shell, and different installation positions and angles of the planar antenna can be selected according to the usage scenario of the filament lamp. When the planar antenna emits electromagnetic waves, it only needs to pass through one layer of the bulb shell, and the same is true when receiving electromagnetic waves. This can effectively reduce the interference received by the microwave induction module, with a long induction distance and a large angle, which can reduce self-excitation and improve consistency. The present utility model cancels the plastic part between the bulb shell and the lamp head, and the appearance can be made the same as that of a common LED filament lamp, which is more acceptable to customers, can meet standardized production, is more convenient during assembly, and can reduce costs to a certain extent.

Detailed implementation manners
[0030] To enable those of ordinary skill in the art to more clearly understand the purpose, technical solutions, and advantages of the present utility model, the following further elaborates on the present utility model in conjunction with the accompanying drawings and embodiments, but the present utility model is not limited to the following embodiments.
[0031] In the description of the present utility model, it should be noted that the orientation or positional relationships indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.
[0032] The utility model provides a microwave induction LED filament lamp, which includes a filament lamp body and a microwave induction module 3. The structure of the filament lamp body is basically the same as that of the existing LED filament lamp, and will not be introduced in detail here. In order to improve the performance of microwave induction, the microwave induction module 3 is arranged in the bulb shell 4 of the filament lamp body. Each wiring terminal of the microwave induction module 3 is respectively connected to the driving module through a wire 8, and the driving module is installed in the lamp holder 1 of the filament lamp body. The type of the bulb shell 4 can be determined according to the application scenario, and it can be a transparent glass bulb shell 4, a frosted glass bulb shell 4, or a glass bulb shell 4 of other colors such as milky white.
[0033] In the utility model, the microwave induction module 3 has a variety of installation methods, and its installation position and installation angle in the bulb shell 4 can be determined according to the application scenario. The following are examples for illustration.
[0034] Embodiment 1: As Figure 2 shown, the microwave induction module 3 is arranged at the overhanging end of the core column 6 of the filament lamp body, and the plane where the microwave induction module 3 is located is arranged substantially perpendicular to the core column 6. The planar antenna 3.1 is located on the front of the microwave induction module 3, away from the overhanging end of the core column 6, and the back of the microwave induction module 3 is arranged close to the overhanging end of the core column 6.
[0035] In this embodiment, the rigidity of the wire 8 connected to the wiring terminal can be used to support and position the microwave induction module 3. In addition, the core column 6 can also support and position the microwave induction module 3 to a certain extent.
[0036] As Figure 2 shown, since the microwave induction module 3 is arranged at the overhanging end of the core column 6 and is within the range surrounded by multiple LED filaments 5, the overhanging ends of the LED filaments 5 are connected by another wire. To maintain the position of the LED filaments 5, an existing metal bracket 7 can be added between the core column 6 and each LED filament 5 for support.
[0037] Embodiment 2: As Figure 3 shown, the difference between this embodiment and Embodiment 1 is that the back of the microwave induction module 3 and the overhanging end of the core column 6 are adhesively fixed by glue 9 to further improve the stability of the microwave induction module 3.
[0038] Embodiment 3: As Figure 4 、 Figure 6As shown in the figure, the difference between this embodiment and Embodiment 1 is that a through hole 3.2 is provided on the microwave induction module 3, and the through hole 3.2 is sleeved on the core column 6 of the filament lamp body. A clearance fit or an interference fit is provided between the through hole 3.2 and the core column 6, which can define the position of the microwave induction module 3 and improve the stability of the microwave induction module 3. The position of the through hole 3.2 can be determined according to the circuit structure on the microwave induction module 3, and the area where the planar antenna 3.1 is located should be avoided as much as possible.
[0039] Embodiment 4: As Figure 5 , Figure 6 shown in the figure, a C-shaped bayonet 3.3 is provided on the edge of the microwave induction module 3, and the bayonet 3.3 is clamped on the outer wall of the core column 6 of the filament lamp body. The bayonet 3.3 can be provided on any edge of the microwave induction module 3.
[0040] Embodiment 5: As Figure 7 shown in the figure, the microwave induction module 3 is arranged on the side of the core column 6 of the filament lamp body. The planar antenna 3.1 on the front of the microwave induction module 3 is arranged away from the core column 6, and the planar antenna 3.1 is arranged parallel to the core column 6. In this embodiment, the microwave induction module 3 can be supported by the rigidity of the wire 8, or glue can be applied between the back of the microwave induction module 3 and the core column 6 to further bond and fix it with the glue 9.
[0041] Embodiment 6: As Figure 8 shown in the figure, the difference between this embodiment and Embodiment 5 is that the planar antenna 3.1 in this embodiment forms a certain angle with the core column 6, and this angle is determined according to the use scenario, for example, 30° - 60°.
[0042] Embodiment 7: As Figure 9 shown in the figure, the difference between this embodiment and Embodiment 6 is that in this embodiment, an intermediate connector 10 is used to fix the microwave induction module 3 on the side of the core column 6 of the filament lamp body. Obviously, the structure of the intermediate connector 10 has various forms. For example, the intermediate connector 10 has a first connecting portion 10.1 and a second connecting portion 10.2 connected together; the first connecting portion 10.1 is in an O shape and sleeved on the core column 6 (a recommended interference fit between the two), or the first connecting portion 10.1 is a U-shaped structure, or a C-shaped structure as Figure 10 shown in the figure. The U-shaped structure / C-shaped structure is clamped on the core column 6; the second connecting portion 10.2 is a snap structure with at least two hooks, and the hooks are used to hook the edge of the microwave induction module 3 to realize the connection between the microwave induction module 3 and the core column 6.
[0043] Another form of the intermediate connecting member 10 is as follows: A bracket is bent from a wire (similar to the metal bracket structure used to support the LED filament in the existing LED filament lamp). The middle section of the bracket is clamped tightly on the core column 6, and both ends are bent into hook shapes and hooked on the edge of the microwave induction module 3 to realize the connection between the microwave induction module 3 and the core column 6.
[0044] Embodiment 8: As Figure 11 shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the microwave induction module 3 is located outside the overhanging end of the core column 6. The overhanging end of the LED filament 5 is connected to the overhanging end of the core column through another wire, and the wire of the LED filament 5 and the wire 8 of the microwave induction module 3 are insulated from each other.
[0045] In this embodiment, the microwave induction module 3 can be supported by the rigidity of the wire 8, or referring to Embodiment 7, an intermediate connecting member can be used to connect the microwave induction module 3 and the core column 6 to further improve the stability of the microwave induction module 3.
[0046] Embodiment 9: As Figure 12 shown, the difference between this embodiment and Embodiment 7 is that the microwave induction module 3 is located outside the LED filament.
[0047] The present utility model adapts to different application scenarios by changing the installation position and angle of the microwave induction module 3, enabling the planar antenna 3.1 to better face the direction to be detected, with less interference in the process of electromagnetic wave emission and reception, capable of increasing the induction distance and angle, reducing self-excitation, improving the consistency of the product, making the appearance of the product the same as that of a common LED filament lamp, improving the acceptance degree of customers, and enabling standardized production and reducing production costs.
[0048] The above are only the preferred embodiments of the present utility model. For those skilled in the art, various modifications and changes can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
