[0001] The utility model relates to the technical field of lighting, in particular to a lamp. Background Art

[0002] The power supply of LED filament lamps is generally placed in the metal lamp holder or plastic parts. Power supplies / wireless modules with intelligent functions (networking or remote control to adjust the intensity and color of light) require antennas. Generally, when the operating frequency of the wireless module is fixed, the wavelength λ=c / f (c is the speed of light, f is the operating frequency) can be converted. Generally, the antenna performance is optimal when the antenna length is 1 / 4 wavelength. Due to the volume and process limitations of LED filament lamps, the intelligent power supply / wireless module antenna is generally placed in the metal lamp holder or the glass core column speaker base or plastic parts. The metal lamp holder shields the intelligent power supply / wireless module signal, and the internal space of the glass core column speaker base and plastic parts is limited, and the optimal antenna length cannot be placed, which will affect the signal.

[0036] like Figures 1 to 4 As shown, some embodiments of the present invention provide a lamp, which is mainly used to increase the length of the antenna and reduce the impact on the signal.

[0037] The lamp includes a lamp holder 100 , a bulb shell 200 , a control board 300 , a base 400 , an antenna 500 and a filament 600 .

[0038] The lamp holder 100 is provided with a mounting slot 110 .

[0039] The bulb shell 200 defines a receiving cavity 210, and one end of the bulb shell 200 is at least partially received in the mounting groove 110 and sealed to the notch of the mounting groove 110 to form a sealed connection structure to prevent external dust, impurities or liquid from entering the bulb shell 200 or the lamp holder 100, thereby ensuring the service life of the lamp.

[0040] The connection between the bulb shell 200 and the lamp holder 100 includes any one of bonding, clamping and threaded connection.

[0041] In addition, the control board 300 is disposed in the mounting groove 110 , the control board 300 is connected to the inner wall of the lamp holder 100 , and the control board 300 is electrically connected to the lamp holder 100 , so that the control board 300 can be connected to an external power source through the lamp holder 100 .

[0042] The base 400 is disposed in the accommodating cavity 210 , and the base 400 is connected to a side of the bulb 200 close to the lamp holder 100 .

[0043] The connection between the base 400 and the bulb 200 includes any one of bonding, clamping or integral molding.

[0044] In this embodiment, the base 400 and the bulb shell 200 are integrally connected to improve the stability of the connection between the base 400 and the bulb shell 200 .

[0045] In addition, the antenna 500 is disposed on the base 400 , and the antenna 500 is electrically connected to the control board 300 .

[0046] It should be noted that the length and shape of the end of the antenna 500 away from the base 400 can be specifically set according to actual conditions, so that the length of the antenna 500 reaches 1 / 4 wavelength, thereby improving the performance of the antenna 500.

[0047] A plurality of filaments 600 are disposed in the accommodating cavity 210 at intervals, and each of the filaments 600 is connected to the control board 300 so that the start or stop of the filament 600 can be controlled by the control board 300 .

[0048] It should be noted that by electrically connecting the antenna 500 to the control board 300 , the user can adjust the length and shape of the antenna 500 according to actual needs to reduce the impact of interference signals on the antenna 500 and improve the stability of signal reception by the antenna 500 .

[0049] In this embodiment, the control board 300 is a PCB (Printed Circuit Board), that is, a printed circuit board or a printed circuit board.

[0050] like Figure 2 and Figure 3 As shown, in some embodiments of the utility model, a plurality of first guide wires 700 are provided in the base 400, one end of the first guide wire 700 is passed through the base 400 and is electrically connected to the control board 300, and the other end of the first guide wire 700 is connected to one end of the filament 600 close to the base 400, thereby electrically connecting the filament 600 to the control board 300 through the first guide wire 700.

[0051] It should be noted that the plurality of first guide wires 700 are arranged at intervals on the base 400 to avoid a short circuit caused by contact between two adjacent first guide wires 700 .

[0052] Furthermore, one end of the first guide wire 700 away from the base 400 is bent toward a side away from the antenna 500 to further avoid a contact short circuit between adjacent first guide wires 700.

[0053] like Figure 4 As shown, in some embodiments of the present invention, the antenna 500 is a conductive column, and the high conductive column is a metal conductive column.

[0054] In this embodiment, the antenna 500 is disposed at an end of the base 400 away from the lamp holder 100 , and the axis of the antenna 500 coincides with the axis of the bulb 200 .

[0055] Specifically, one end close to the lamp holder 100 is embedded in the base 400 to provide support and fixation for the antenna 500 through the base 400 .

[0056] The end of the filament 600 away from the base 400 is electrically connected to the end of the conductive column away from the lamp holder 100 .

[0057] like Figure 4 As shown, in some embodiments of the present invention, the antenna 500 is provided with at least one lead-out portion 510 at one end close to the base 400. It is understandable that the number of the lead-out portions 510 can be one, two, or more than two, and can be specifically set according to actual conditions.

[0058] It should be noted that, when there are multiple lead-out portions 510 , the multiple lead-out portions 510 are arranged at intervals.

[0059] Among them, one end of the lead-out part 510 is connected to one end of the antenna 500 close to the base 400, and the other end of the lead-out part 510 is passed through the base 400 and connected to the control board 300, so that the antenna 500 is connected to the control board 300 through the lead-out part 510.

[0060] like Figure 2 and Figure 3As shown, in some embodiments of the utility model, the lamp includes a stem 800, the stem 800 is arranged in the accommodating cavity 210, and one end of the stem 800 is connected to the end of the base 400 away from the lamp holder 100. Specifically, the end of the stem 800 close to the lamp holder 100 and the end of the bulb shell 200 close to the lamp holder 100 are formed by flame welding, and the accommodating cavity 210 is evacuated to form a closed hair bubble. It should be noted that the hair bubble mentioned here refers to the bulb shell 200 with the stem 800.

[0061] The axis of the stem 800 , the axis of the base 400 and the axis of the bulb shell 200 coincide with each other, and there is a gap between the stem 800 and the inner wall of the bulb shell 200 .

[0062] In this embodiment, the core column 800 is a transparent glass column.

[0063] Among them, a plurality of second guide wires 900 are provided at one end of the core column 800 away from the base 400, and the second guide wires 900 are connected to the control board 300. The end of the filament 600 away from the base 400 is connected to the second guide wire 900, so that the filament 600 is connected to the control board 300 through the first guide wire 700 and the second guide wire 900.

[0064] It should be noted that the plurality of second guide wires 900 are arranged at intervals so that the light emission of each filament 600 can be individually controlled by the control board 300 to enhance the diversity of the light emission of the bulb.

[0065] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the antenna 500 is disposed on one side of the core column 800 , and there is a gap between the antenna 500 and the filament 600 to avoid contact between the antenna 500 and the filament 600 .

[0066] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, one end of the antenna 500 away from the base 400 is configured to be spiral, so as to further ensure the stability of the antenna 500 in receiving signals.

[0067] In this embodiment, by setting one end of the antenna 500 to be at least in any one of a spiral, a zigzag, or a curve shape, or a combination of two or more of them, it can be specifically set according to actual conditions so that the user can lengthen or compress the length of the antenna 500 according to actual needs to adjust the stability of the antenna 500 receiving the signal.

[0068] In addition, in some embodiments, the end of the antenna 500 away from the base 400 can also be set to other shapes such as polygonal, circular, etc. to ensure the stability of the antenna 500 receiving signals, which can be specifically set according to actual conditions.

[0069] It should be noted that the radiation direction of the helical antenna is related to the circumference of the helical line.

[0070] When the circumference of the spiral is much smaller than a wavelength, the direction of the strongest radiation is perpendicular to the spiral axis; when the circumference of the spiral is on the order of a wavelength, the strongest radiation appears in the direction of the spiral axis.

[0071] In this embodiment, the length of the helical portion of the antenna 500 is equal to or greater than one wavelength, and the radius of the helical portion is between one eighth and one quarter of a wavelength.

[0072] Specifically, the helical antenna has an extremely wide frequency band and can cover a wider frequency range, and is suitable for a variety of wireless communication applications; the helical antenna has a wider beam width, which is conducive to covering a larger area and improving communication reliability; compared with other types of antennas 500, the helical antenna is easier to manufacture, thereby reducing costs.

[0073] In addition, the helical antenna has a very outstanding anti-interference ability, which can resist the influence of interference signals on the antenna 500, thereby ensuring the communication quality. Compared with other commonly used antenna 500 types, such as mast antennas, whip antennas, etc., the helical antenna has a smaller volume and size, which is easy to arrange and install.

[0074] like Figure 2 As shown, in some embodiments of the present invention, the lamp includes a power module 1100 , and the power module 1100 is connected to the control board 300 to supply power to the control board 300 through the power module 1100 .

[0075] like Figure 2 As shown, in some embodiments of the present invention, the lamp includes a wireless module 1000 , and the wireless module 1000 is connected to the control board 300 .

[0076] It should be noted that the wireless module 1000 is used to exchange data with other communication devices. The wireless module 1000 is powered by the power module 1100. The wireless module 1000 has a communication protocol serial port, which is connected to the power module 1100. At the same time, the communication protocol serial port is used to control the working mode and status of the power module 1100.

[0077] Specifically, the wireless module 1000 communicates with an external communication device through the antenna 500, and executes external communication instructions through the power module 1100, outputting different working instructions to the control board 300 to allow the control board 300 to control the working state of the filament 600, thereby meeting the user's different needs for light.

[0078] In some embodiments of the present invention, the antenna 500 is any one of a Bluetooth antenna 500 , a ZigBee antenna 500 , a WiFi antenna 500 , a Z-Wave antenna 500 , and a RF antenna 500 .

[0079] In some embodiments of the present invention, the lamp holder 100 includes a shell, an insulating part and a conductive part.

[0080] Specifically, a portion of the shell is sleeved on one end of the bulb 200 close to the base 400, and the side of the shell facing away from the bulb 200 is sleeved on the insulating part. The insulating part has a mounting hole, and the conductive part is arranged in the mounting hole and sealed on the mounting hole to form a sealed connection structure.

[0081] It should be noted that the housing is a conductive shell, and the housing and the conductive part are electrically connected to the control board 300 respectively, that is, the control board 300 can be electrically connected to an external power source through the lamp holder 100 .

[0082] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0083] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0084] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
