However, wireless communication technology is the basis for the realization of intelligent LED lights. Only LED lights with wireless communication technology can achieve interconnection, real-time monitoring and centralized control. At present, the main wireless communication technologies used are as follows:
[0003] (1) WiFi technology

It has stable performance, large bandwidth and long transmission distance, so it is widely used in the wireless communication field of LED lights. LED landscape lights using Wi-Fi technology can achieve remote monitoring and control, further improving the safety and reliability of lighting. For example, CN211792155U provides a WiFi-controlled ultra-thin LED floodlight. After receiving the action information, the server sends corresponding functional instructions to the WiFi Module through the mobile network and router to achieve control of the floodlight. CN205546033U provides an LEDWiFi intelligent power control module. Users can send control instructions to the control module through the WIFI module to achieve brightness adjustment and color temperature adjustment of the LED lamp.

It is suitable for IoT application scenarios with low requirements for transmission delay. LED lights using ZigBee technology can establish a wireless sensor network to achieve mutual collaboration between lamps and data collection from sensors. For example, CN105066056A provides a Zigbee smart bulb lamp, a Zigbee module, which receives wireless signals from the Internet of Things and outputs corresponding control signals; the control module selects the working LED dimming and color adjustment drive control module according to the control signal and outputs the adjustment signal; the LED dimming and color adjustment drive control module adjusts the brightness of the LED bulb group in the corresponding LED light source board according to the adjustment signal; CN106488625A provides an intelligent energy-saving street lamp based on ZigBee network communication, including a control station, and multiple high-power ZigBee gateways communicating with the ZigBee network, and multiple street lamps communicating with the high-power ZigBee gateway through the ZigBee network; the high-power ZigBee gateway includes two independent first and second ZigBee systems; the first ZigBee system is electrically connected to a power amplifier.
[0007] (3) LORA technology
[0008] LORA is a low-power, long-distance wireless communication technology suitable for low-speed data transmission; LED lights using LORA technology can achieve long-distance, low-power wireless communication, and have the characteristics of anti-interference and anti-attenuation.
[0009] For example, CN108337779A provides a wireless single-lamp control system based on LORA technology, including a system host, a LORA wireless coordinator and a LORA wireless single-lamp controller. The system host and the LORA wireless coordinator communicate serially through a bus, the LORA wireless coordinator and the LORA wireless single-lamp controller are connected through a wireless network, and the LORA wireless single-lamp controller is connected to an external lamp; CN111295025A provides an energy-saving urban smart street lamp using LORA technology, including a LORA system, a central control system, a sensor detection module, a data collection module, a user system, a smart street lamp control system and a smart street lamp. The sensor detection module, the central control system, the user system and the smart street lamp control system are all connected to the LORA system, the output end of the data collection module is connected to the input end of the sensor detection module, the output end of the sensor detection module is connected to the input end of the central control system through the LORA system, the output end of the central control system is connected to the input end of the smart street lamp control system through the LORA system, the user system is connected to the central control system through the LORA system, and the smart street lamp control system is connected to the smart street lamp.
[0010] LED lamps adopt several of the above technologies, and realizing wireless communication also requires the use of antennas to receive related signals. For example, CN213305817U provides an LED driver power supply and lamp with a wireless communication module, and the antenna is arranged outside the LED driver power supply body and electrically connected to the communication module; the antenna shape includes rod type, mushroom type, suction cup type, folding type, etc., to improve the antenna's ability to receive and send signals; CN214205899U provides an LED driver power supply and lamp with an external wireless communication module, and the antenna is arranged inside the communication terminal and electrically connected; CN104654075A provides an L An ED lamp includes an LED module, a heat dissipation module and a power module. An antenna is arranged on the drive control module, and the antenna is arranged near the notch. For another example, CN202873121U provides a wireless intelligently controlled LED drive power supply, a wireless intelligently controlled LED drive power supply, including a wireless communication module, an antenna, a processor module, and an LED drive power supply. The LED drive power supply is an integrated circuit board structure. The circuit board has an LED drive power supply, a processor module and a wireless communication module connected in sequence by wires. The wireless communication module is equipped with an antenna or uses the copper foil on the circuit board as an antenna. CN107435874A provides an LED plant lamp with wirelessly controlled spectral ratio and adjustable light intensity, and an antenna connected to the LED aluminum substrate is arranged on the side baffle.
[0011] The corresponding structure of the above-mentioned patent requires an external antenna for long-distance wireless communication; if the external antenna is not added, the communication distance is short and the communication control signal cannot be stably and reliably received and transmitted. However, the external antenna will cause the waterproof seal of the LED lamp to be poor, affecting the service life of the LED lamp; the built-in antenna is affected by components such as the lampshade. Mainly, in order to improve the transmittance of the lampshade, some metal particles are generally added. These metal particles will shield the signal, thereby causing interference to the signal reception or transmission, resulting in failure of wireless control. Summary of the invention

[0059] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.
[0060] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0061] 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.
[0062] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0063] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0064] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0065] The structure disclosed in the prior art patent requires an external antenna for long-distance wireless communication; if the external antenna is not added, the communication distance is short and the communication control signal cannot be stably and reliably received and transmitted. However, considering the sealing and waterproofing problem of LED lamps, these antennas are set in the lampshade, which has the disadvantage that the antenna is short or attached to the PCB board, thereby limiting the distance of wireless communication control and making it difficult to achieve long-distance wireless communication control.
[0066] [Method for providing wireless control of LED lamps]
[0067] The method for providing wireless control of an LED lamp provided by the present invention comprises the following steps:
[0068] The aluminum substrate 32 on which a plurality of LED lamp beads 33 are arranged and fixed in sequence receives a wireless communication signal of an external device, and the wireless communication signal is one of 3G, 4G, 5G, GPRS, Bluetooth, WiFi, ZigBee, 433MHZ, and 2.4GHZ;
[0069] Then the wireless control module 20 performs DC isolation processing on the received wireless communication signal to obtain a high-frequency and low-voltage signal;
[0070] The whole lamp control module 10 sends a dimming signal to the LED module 30 through the BUCK circuit 12, and the BUCK circuit 12 sends a feedback signal to the feedback circuit 16, and transmits the feedback signal to the aluminum substrate 32 via the wireless control module 20 to an external device. The external device includes one of a mobile phone, a PAD, a computer and a cloud server, preferably a mobile phone or a PAD, and a software program or an APP is set on the external device.
[0071] The LED lamp of the present invention adopts an aluminum substrate 32 to replace the built-in antenna, ensuring that the sealing effect of the LED lamp reaches IP66 level, and the sealing effect is good. At the same time, the aluminum substrate 32 has a large receiving area, the signal is less affected, and the signal can be effectively prevented from being affected by the heat dissipation of the LED lamp, thereby maintaining a good signal receiving capability.
[0072] However, if Figure 2As shown, a number of LED lamp beads 33 are arranged and fixed in sequence on the aluminum substrate 32. For example, 100 660nm red light LED lamp beads 33 and 100 460nm blue light LED lamp beads 33 are provided on the bottom surface of the LED aluminum substrate 32. The LED lamp beads 33 are arranged in parallel to form a magnetic field. Therefore, the signal received by the aluminum substrate 32 will be affected by the magnetic field, which greatly affects the reception of the signal.
[0073] Based on this, the LED lamp is provided with at least two aluminum substrates 32, and the area of the aluminum substrate 32 is effectively increased. On the one hand, the signal receiving area is increased, and on the other hand, several lamp beads are dispersed to increase the interval between the lamp beads, thereby effectively reducing the influence of the electric field and the magnetic field.
[0074] like Figure 5 and Figure 6 As shown, the system for providing wireless control of LED lamps in this embodiment includes: a wireless control module 20 and an LED module 30 , and the wireless control module 20 and the LED module 30 are electrically connected to the whole lamp control module 10 .
[0075] In some embodiments of the present invention, the LED module 30 includes a housing 31, an aluminum substrate 32 disposed inside the housing 31, and a plurality of LED lamp beads 33 arranged and fixed on the aluminum substrate 32 in sequence. The aluminum substrate 32 can communicate wirelessly with external devices.
[0076] In some embodiments of the present invention, Figure 7 As shown, the wireless control module 20 includes a wireless receiving chip 21, a DC isolation circuit 22 and a control chip 23. The DC isolation circuit 22 is arranged between the aluminum substrate 32 and the wireless receiving chip 21. The DC isolation circuit 22 can isolate the wireless communication signal received by the aluminum substrate 32 and transmit it to the wireless receiving chip 21; the wireless receiving chip 21 is electrically connected to the control chip 23, and the control chip 23 is electrically connected to the whole lamp control module 10.
[0077] The LED lamp beads 33 are mounted on the aluminum substrate 32. The aluminum substrate 32 not only provides conductivity, but also has very good heat dissipation performance, which can ensure that the lamp beads work normally at a temperature exceeding 60 degrees and will not cause the LED lamp beads 33 to be burned.
[0078] like Figure 1 and Figure 2 As shown, four accommodating cavities are provided on the housing 31, and an aluminum substrate 32 is installed in the accommodating cavities. Considering the problem of structural strength, the housing 31 is made of metal material, such as aluminum alloy, to effectively control the weight of the entire lamp.
[0079] For example Figure 2The LED lamp shown in the figure has four aluminum substrates 32, and the four aluminum substrates 32 are close to the outside relative to the shell to reduce the shielding effect of the shell as much as possible. The present invention adopts the aluminum substrate 32 to receive wireless communication signals. The effective area of the aluminum substrate 32 is relatively large. Compared with general antennas (including rod-type, mushroom-type, suction cup-type, folding type), the receiving area is increased by hundreds or even thousands of times, which is conducive to signal reception; at the same time, the LED lamp adopts the current conventional waterproof sealing, and no special waterproof sealing treatment is required. The Goel waterproof airtightness tester of Shenzhen Goel Technology Co., Ltd. is used for detection. The waterproof level of the LED lamp of the present invention reaches IP66.
[0080] Among them, IP66 means that the product is completely protected from the intrusion of foreign objects and dust. When subjected to violent wave impact or strong water spray, the amount of water entering the appliance should not reach a harmful effect.
[0081] However, LED lamps cannot be directly connected to 220V AC power and need to be used in conjunction with an LED driver power supply. The LED driver power supply converts the AC power into the DC power required by the LED lamp to drive the light emission. The aluminum substrate 32 has a conductor that provides power to the LED lamp beads 33. Therefore, there are wireless communication signals and DC signals on the aluminum substrate 32. The received wireless communication signals are isolated by the DC isolation circuit 22. The DC isolation circuit 22 includes an L5 inductor 221 and a C8 capacitor 222. The above-mentioned L5 inductor 221 and the C8 capacitor 222 are connected in series, and grounding protection capacitors C9 and C10 are arranged at both ends of the L5 inductor 221.
[0082] In the present invention, there is no specific limitation on the parameters of the L5 inductor 221 and the C8 capacitor 222, and commercially available products can meet the use requirements.
[0083] In some embodiments of the present invention, the whole lamp control module 10 includes a control circuit 11, a BUCK circuit 12, an APFC circuit 13, a rectifier circuit 14 and an EMC circuit 15; a feedback circuit 16 is provided between the BUCK circuit 12 and the wireless control module 20, and the feedback circuit 16 is electrically connected to the control circuit 11; the BUCK circuit 12 is electrically connected to the aluminum substrate 32; the control circuit 11, the BUCK circuit 12, the APFC circuit 13, the rectifier circuit 14, the EMC circuit 15 and the feedback circuit 16 are all circuits of the prior art, and the above circuits are combined, and the LED aluminum substrate acts as a communication antenna, and DC isolation processing is performed to ensure that the communication end receives and transmits signals that are stable high-frequency and low-voltage signals, thereby realizing two-way wireless communication.
[0084] In addition, if Figure 4As shown, the aluminum substrate 32 may also adopt a layered structure. For example, the aluminum substrate 32 includes a first substrate 321 and a second substrate 322. A ceramic plate 323 is sandwiched between the first substrate 321 and the second substrate 322. Both the first substrate 321 and the second substrate 322 are aluminum plates. A plurality of LED lamp beads 33 are sequentially arranged and fixed on the first substrate 321. The second substrate 322 is fixedly connected to the shell 31. The shell 31 is made of aluminum profile.
[0085] The above-mentioned first substrate 321 is arranged downward, the ceramic plate 323 isolates the first substrate 321 and the second substrate 322, the second substrate 322 is connected to the shell 31 and receives the wireless communication signal through the aluminum profile shell 31, and the wireless communication signal is received through the shell 31. In order to better receive the wireless communication signal, the wireless communication signal still needs to be isolated; the isolation is performed by the isolation circuit 22, and the isolation circuit 22 includes an L5 inductor 221 and a C8 capacitor 222. The above-mentioned L5 inductor 221 and the C8 capacitor 222 are connected in series, and grounding protection capacitors C9 and C10 are arranged at both ends of the L5 inductor 221.
[0086] In order to better achieve the heat dissipation of the LED lamp, without affecting the size of the first substrate 321 and the second substrate 322, a layer of graphene is plated on the surface of the first substrate 321 and the second substrate 322. The thickness of the graphene layer is 0.1-5 microns, preferably 0.1 microns, 1 micron, 2 microns, 3 microns, 4 microns and 5 microns. The structure of the graphene is a sheet, and nano-silver particles, nano-gold particles, nano-nickel particles or nano-tin particles are filled between the graphene sheets. These metal particles serve to connect the graphene sheets to enhance the heat dissipation and conductivity. At the same time, due to the nature of the graphene layer itself (thickness is relatively thin 0.34nm), it hardly absorbs wireless communication signals.
[0087] However, after on-site comparison, it was found that the first substrate 321 and the second substrate 322 coated with the graphene layer have better performance than the first substrate 321 and the second substrate 322 not coated with the graphene layer. On the one hand, the graphene will be oriented under the action of the external magnetic field, and it is more prominent in the heat dissipation and conductivity of the surface; on the other hand, the use of directional graphene solves the problem of "due to the skin effect, as the frequency of the wireless communication signal increases, the resistance of the aluminum substrate surface increases sharply, resulting in a decrease in the amplitude of the electromagnetic waves propagating on the surface of the aluminum substrate."
[0088] In order to verify the performance of the coated aluminum substrate, a 433MHZ wireless communication signal was used, and then on-site debugging was carried out. The debugging content included: turning on the light, turning off the light, 10% brightness, 20%, 30%, 40%, 50% brightness, 60%, 70%, 80%, 90% and 100% brightness. At the same time, through the feedback of the LED light, the current status of the LED light can be seen on external devices such as mobile phone APP.
[0089] It should be noted that, through on-site debugging and use, it was found that the normal use of the LED lamp will affect the reception and transmission of signals by the aluminum substrate 32 to a certain extent, and the corresponding problem can be alleviated by coating graphene. Through on-site debugging and comparison, the delay of the detection signal is reduced by 10ms-50ms compared with the uncoated aluminum substrate.
[0090] The wirelessly controlled LED lamp of the present invention comprises: a whole lamp control module 10 , a wireless control module 20 and an LED module 30 . The wireless control module 20 and the LED module 30 are electrically connected to the whole lamp control module 10 .
