[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] At present, traditional smart lighting products generally have a main control area and a lighting area. The main control area is equipped with a driver board inside and a glass cover outside to protect the driver board. At the same time, the RF module and antenna are installed separately on the driver board. The RF module is generally installed in the corner of the driver board, and the antenna is set outside, and the RF module and antenna are connected through a feeder. However, this installation method will cause large metal devices on the driver board (such as capacitors with large capacitance values ​​and inductors with large inductance values) to be close to the antenna, causing the metal devices to affect the wave impedance characteristics of the antenna, interfere with the antenna radiation, and reduce the antenna radiation efficiency. It will also make the RF module prone to electromagnetic compatibility problems, affecting the spurious and radiation of the RF module. At the same time, the feeder used to connect the RF module and the antenna also has resistance loss and insulation layer dielectric loss. The longer the feeder, the higher the operating frequency, and the more energy loss.

[0043] To this end, the present application provides a communication device, which directly sets the RF module and antenna on a glass cover far away from the driving board, so that the RF module and antenna are far away from the driving board, thereby reducing the impact of metal devices on the driving board on the RF module and antenna, so that the antenna has better clearance, reduces interference, and improves the antenna radiation efficiency. At the same time, it also reduces the electromagnetic compatibility impact of the RF module. In addition, because the use of feeders is avoided, the resistance loss and dielectric loss of the insulating layer are reduced, the energy loss is reduced, and the cost is reduced.

[0044] The communication device provided in the present application is described below by way of example in conjunction with the accompanying drawings.

[0045] Figure 1 A first structural diagram of a communication device provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, exemplarily, a communication device includes an antenna module 1, a radio frequency module 2 and a glass module 3;

[0046] The antenna module 1 is plated on the glass module 3 through a metal film, and the radio frequency module 2 is installed on the glass module 3 and is electrically connected to the antenna module 2 through the metal film;

[0047] The antenna module 1 is configured to receive a first external signal and send it to the radio frequency module, or to transmit a second external signal;

[0048] The radio frequency module 2 is configured to process the first external signal to obtain the first information, or to process the second information to obtain the second external signal and send it to the antenna module.

[0049] In the application, the metal film is directly plated into the required shape or pattern as the antenna module, and then the antenna module and the RF module are installed on the glass module farthest from the driver board, and the metal film is used instead of the feeder to connect the antenna module and the RF module. Therefore, because the RF module is installed on the glass module far away from the driver board, the use of copper clad board on the driver board is reduced, space is saved, cost is reduced, and the impact of electromagnetic compatibility is reduced; because the antenna module is installed on the glass module, it is far away from the driver board, forming a better clearance (generally, the distance from the metal device to the antenna is greater than 10mm, there will be better clearance, and less than 5mm, the interference is too large); at the same time, the antenna module and the RF module are electrically connected through the metal film, and no external feeder is required, which reduces energy loss and reduces costs. Among them, the metal film has good stability and conductivity. For example, silver oxide and other metal materials with good conductivity and easy matching of their own impedance characteristics can be used.

[0050] Figure 2 A second structural diagram of a communication device provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, exemplarily, the communication device further includes a power supply module 4;

[0051] The power supply module 4 is installed on the glass module 3 and is electrically connected to the radio frequency module 2;

[0052] The power supply module 4 is configured to provide power to the RF module 2 .

[0053] In application, by installing a power supply module on the glass module and electrically connecting the power supply module to the RF module, and thus connecting an external power source through the power supply module, power can be provided to the RF module, so that the RF module and the antenna module can work normally.

[0054] Figure 3 A third structural diagram of a communication device provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, exemplarily, the power supply module 4 includes a power supply terminal 41 and a metal film wire 42;

[0055] The metal film wire 42 connects the power supply terminal 41 and the radio frequency module 3;

[0056] A power supply terminal 41 is configured to provide an external power supply port;

[0057] The metal film conductor 42 is configured to transmit the power provided by the external power supply port to the RF module 3 .

[0058] In application, the power supply terminals on the power supply module are connected to the power supply terminals on the driver board, so that the electric energy on the driver board is transmitted to the metal film wire through the power supply terminals, and then transmitted to the RF module through the metal film wire. The metal film wire of the present application is a metal film directly printed on the glass module, thereby reducing the use of feeders in traditional power supply modules, reducing energy loss, and reducing costs. At the same time, because the operating voltage of the RF module is relatively low (generally 3.3V), it is a low-voltage DC power supply, so the voltage flowing through the metal module wire is also relatively low, generally 3.3V, and will not damage the glass module, so the metal film wire can be directly plated on the glass module.

[0059] Exemplarily, the power supply terminal includes a male and female terminal or a pin header connector.

[0060] In applications, the power supply terminals can use male and female terminals or pin header connectors. For example, the power supply terminals of the power supply module can use female terminals, and the power supply terminals on the driver board can use male terminals. By plugging the female terminals and the male terminals, the power on the driver module can be transmitted to the RF module through the male terminals, the female terminals and the metal film wires. The power supply terminals of the power supply module and the power supply terminals of the driver board can also use pin header connectors. After the power supply terminals of the power supply module and the power supply terminals of the driver board are connected, the driver board supplies power to the RF module through the power supply terminals, so that the RF module can work normally.

[0061] Exemplarily, the radio frequency module adopts a packaging structure or a patch structure.

[0062] In applications, the RF module adopts a packaging structure or a patch structure, and the components of the RF module that were originally laid flat on the driver board are integrated into a packaging structure or a patch structure with a smaller volume and area, thereby reducing the area occupied by the RF module on the glass module and facilitating installation. In actual production, a solder pad can be reserved on the surface of the glass module for the RF module patch.

[0063] like Figure 3 As shown, exemplarily, the antenna module adopts a multi-branch antenna.

[0064] In application, the antenna module may adopt a multi-branch antenna, which is obtained by optimizing the planar inverted-F antenna (PIFA), mainly by adding branches to the PIFA antenna, adjusting the capacitive performance of the antenna, and improving the radiation efficiency of the antenna.

[0065] like Figure 3 As shown, exemplarily, the multi-branch antenna includes an E-shaped branch and an L-shaped branch, and one corner of the E-shaped branch is connected to one end of the L-shaped branch.

[0066] In application, the shape or pattern of the multi-branch antenna can be designed according to actual needs. For example, the multi-branch antenna can include an E-shaped branch and an L-shaped branch, one corner of the E-shaped branch is connected to one end of the L-shaped branch, and the extension direction of the E-shaped branch is the same as the extension direction of the L-shaped branch. That is, a horizontal branch is added to the upper part of the inverted F shape, and a horizontal branch is added to the bottom, so as to adjust the capacitive performance of the antenna and improve the radiation efficiency of the antenna.

[0067] Exemplarily, the width of the middle branch of the E-shaped branch is adjustable.

[0068] In application, a multi-branch antenna is plated with a metal film, so that the capacitance and inductance of the antenna can be adjusted by adjusting the branch width of the multi-branch antenna (ie, the branch in the middle of the E shape), and the antenna has a small size, a simple structure, and is easy to match.

[0069] Figure 4 The S11 simulation diagram of the antenna module of the communication device provided in the embodiment of the present application is as follows: Figure 4 As shown, in microwave theory, the scattering (S) parameter matrix is ​​used to quantitatively describe a multi-port network. A single-port network is a special type of multi-port network, and its S-matrix degenerates into a single element S11. For antennas, the definition of S11 is the same as that of the reflection coefficient, that is, the definition is:

[0070] S11=Γ=V reflected / Vincident

[0071] Among them, V reflected Represents the voltage amplitude of the reflected wave, V incident represents the voltage amplitude of the incident wave;

[0072] In the field of antennas, S11 below -10dB is often used as one of the indicators of antenna performance. Figure 4 It can be seen that the S11 of the multi-branch antenna of the present application is lower than -10dB in the 2.4GHz to 2.5GHz frequency band, and the bandwidth exceeds 100MHz, which meets the antenna performance requirements.

[0073] Figure 5 This is a Smith Chart simulation diagram of the antenna module of the communication device provided in the embodiment of the present application, such as Figure 5 As shown in the figure, the impedance represented by the Smith Chart is the normalized impedance and normalized admittance obtained by normalizing the actual impedance relative to the system characteristic impedance. Its characteristic is that the equal resistance circles are tangent to the point (1,0) and the center of the circle is located at Figure 5 On the horizontal axis, as the resistance value increases, the radius of the equal resistance circle decreases. The resistance of the leftmost point in the original image is 0, and the resistance of the rightmost point is +∞. The antenna is also an impedance, that is,

[0074] Z=R+jX,

[0075] According to the maximum power transfer theorem, when the antenna characteristic impedance = output impedance, that is, when the antenna only has resistance characteristics and no capacitance and inductance characteristics, the antenna can radiate maximum power; Figure 5 It can be seen that the center frequency 2.45 GHz is closer to the center of the circle (1,0), indicating that the antenna impedance characteristics are good.

[0076] Figure 6 The radiation efficiency simulation diagram of the antenna module of the communication device provided in the embodiment of the present application is as follows: Figure 6 As shown, in the field of antennas, antenna radiation efficiency can also be used as an indicator of antenna performance, and its definition is:

[0077] Efficiency=P radiated / P total available

[0078] Among them, P radiated Represents the total radiated power, P total available is the total input power of the signal source; the antenna radiation efficiency is a value between 0 and 1. The larger the value, the better the radiation performance of the antenna. It is generally believed that an antenna with a radiation efficiency of 50% is already an antenna with excellent performance. Figure 6It can be seen that the antenna radiation efficiency of the multi-branch antenna of the present application exceeds 57% in the 2.4 GHz to 2.5 GHz frequency band, meeting the antenna performance requirements.

[0079] Figure 7 The gain simulation diagram of the antenna module of the communication device provided in the embodiment of the present application is as follows: Figure 7 As shown in the figure, antenna gain refers to the ratio of the power density of the signal generated by the actual antenna and the ideal radiation unit at the same point in space under the condition of equal input power. Antenna gain quantitatively describes the degree to which an antenna radiates input power, and is used to measure the ability of an antenna to send and receive signals in a specific direction. In a certain direction, the greater the antenna gain, the farther the electromagnetic wave propagates; Figure 7 It can be seen that the antenna gain is ≥4.9dBi, which means that the antenna can radiate over a longer distance.

[0080] Figure 8 The plane directional diagram of the antenna module of the communication device provided in the embodiment of the present application with a radiation angle of 0 degree, Fig. 9 The radiation angle of the antenna module of the communication device provided in the embodiment of the present application is 90 degrees, as shown in FIG. Figure 8 and Fig. 9 As shown in the figure, the antenna pattern refers to the graph of the relative field strength of the radiation field changing with direction at a certain distance from the antenna. It is usually represented by two mutually perpendicular plane patterns in the direction of the antenna's maximum radiation. The antenna pattern is an important indicator for measuring antenna performance. For PIFA antennas, the more circular the pattern, the more uniform the antenna radiation and the better the omnidirectional performance. Figure 8 and Fig. 9 As shown, the multi-branch antenna of the present application has good omnidirectionality.

[0081] Fig.10 A first structural diagram of the intelligent lighting device provided in the embodiment of the present application is shown in FIG. Fig.10 As shown, for the sake of convenience of explanation, only the parts related to this embodiment are shown. By way of example, an embodiment of the present application provides a smart lighting device, including a communication device and a lighting device 5;

[0082] The communication device is installed inside the lighting device 5 .

[0083] In the application, the communication device is installed inside the lighting device, so that information can be exchanged with the remote terminal through the communication device, and the high-frequency electromagnetic signals in the space are converted into high-frequency current signals on the driver board to realize the user's control function. That is, the collected information of the lighting device is sent to the remote terminal through the communication device, and the control information of the remote terminal is sent to the lighting device through the communication device.

[0084] Fig.11A second structural diagram of the intelligent lighting device provided in the embodiment of the present application is shown in FIG. Fig.11 As shown, illustratively, the lighting device 5 includes an intelligent lighting body 51, a light source assembly 52, and a driving board 53, and the driving board 53 is electrically connected to the light source assembly 51 and the communication device;

[0085] The intelligent lighting body 51 includes a lighting area and a main control area. The light source assembly 52 is installed inside the lighting area, the communication device is installed outside the main control area, and the drive board 53 is installed inside the main control area and away from the communication device.

[0086] In application, the lighting device may also include a fixing bracket and a reflective cup. The fixing bracket is installed outside the intelligent lighting body to fix the intelligent lighting body. The reflective cup is installed around the light source assembly to reflect the light source output and collect light to improve the light transmittance. The AC power is converted into DC power through the driver board and then supplied to the RF module and the light source assembly through the power supply module. The output port of the driver board is generally provided with three single-core wires, a 3.3V power supply line, and two ground wires. The power supply line can be connected to the male terminal and connected to the female terminal on the power supply module, so as to supply power to the RF module through the power supply module. The communication device is installed on the outside of the main control area of ​​the intelligent lighting body, replacing the original glass cover of the main control area (originally mainly used to determine the direction of the light beam and protect the internal structure of the lamp body), so that the communication device is far away from the driver board, and the RF module is installed on the glass module far away from the driver board, which not only reduces the use of copper clad plates on the driver board, saves space, reduces costs, but also reduces the impact of electromagnetic compatibility; the antenna module is installed on the glass module, far away from the driver board, to form a better clearance, improve the antenna radiation performance; at the same time, the antenna module and the RF module are electrically connected through a metal film, avoiding the use of external feeders, reducing energy loss and reducing costs. At the same time, installing the antenna module and the RF module on the inner surface of the glass cover of the lighting device can ensure the mutual conversion of high-frequency electromagnetic signals and high-frequency current signals, and the location is hidden, beautiful, not easy to be detected and damaged, and does not affect the lighting effect of intelligent lighting equipment (such as flashlights).
