[0002] The aforementioned LNB is a device for transmitting and receiving radio frequency signals, and can be connected to different antennas to suit different usage scenarios. The LNB internally includes a main control chip, radio frequency circuitry, etc.

[0003] The LNB can receive remote control information sent by the remote controller and convert the remote control information into radio frequency signals and send them out through the antenna. It can also convert the radio frequency signals received from the antenna into remote sensing information that the remote controller can recognize.

[0004] Therefore, an external antenna is required to use it.

[0005] Existing antennas have a single function: they can only radiate and receive wireless signals and cannot indicate the current working status of the antenna.

[0006] Furthermore, existing LNBs have difficulty detecting whether external antennas are properly connected, making it difficult to protect the LNB from burning out.

[0007] Therefore, in this patent application, the applicant has carefully researched a new technical solution to solve the above problems. Summary of the Invention

[0008] The present invention addresses the shortcomings of the prior art by providing an antenna, a low-frequency head, and a remote control with a light-emitting diode (LED), which integrates the LED onto the antenna, enabling the antenna to have a status indication function.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An antenna with a light-emitting diode includes a substrate and a first oscillator, a second oscillator, a light-emitting diode, and a first isolation circuit disposed on the substrate;

[0011] The positive terminal of the light-emitting diode is connected to the first oscillator through the first isolation circuit, and the negative terminal of the light-emitting diode is connected to the second oscillator;

[0012] It also includes a coaxial feed line, one end of which is connected to the first oscillator and the second oscillator respectively.

[0013] As a preferred embodiment, the first isolation circuit includes a first inductor and a first capacitor;

[0014] One end of the first inductor is connected to the first oscillator, and the other end of the first inductor is connected to one end of the first capacitor and the positive terminal of the light-emitting diode. The other end of the first capacitor and the negative terminal of the light-emitting diode are connected to the second oscillator.

[0015] As a preferred embodiment, a coaxial connector is also included, which is connected to the other end of the coaxial feeder.

[0016] As a preferred embodiment, it also includes a second isolation circuit, a light-emitting diode driving circuit for connecting to the main control circuit of the high-frequency head, and an radio frequency circuit for connecting to the main control circuit of the high-frequency head.

[0017] The LED driving circuit and the radio frequency circuit are respectively connected to the second isolation circuit, and the second isolation circuit is respectively connected to the first oscillator and the second oscillator.

[0018] As a preferred embodiment, a short-circuit protection circuit is also included, and the LED driving circuit is connected to the second isolation circuit through the short-circuit protection circuit.

[0019] A high-frequency head includes an antenna, said antenna being based on the aforementioned antenna with a light-emitting diode.

[0020] As a preferred embodiment, the LNB further includes a LNB main control circuit, and the antenna with light-emitting diodes includes a second isolation circuit, a light-emitting diode driving circuit for connecting to the LNB main control circuit, and a radio frequency circuit for connecting to the LNB main control circuit.

[0021] The main control circuit of the high-frequency head is connected to the LED driving circuit and the radio frequency circuit respectively; the LED driving circuit and the radio frequency circuit are connected to the second isolation circuit respectively, and the second isolation circuit is connected to the first oscillator and the second oscillator respectively.

[0022] As a preferred embodiment, the high-frequency head also includes a power management circuit for power supply.

[0023] A remote control includes the aforementioned high-frequency head.

[0024] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it mainly integrates the light-emitting diode onto the antenna through the cooperation of the first isolation circuit and the light-emitting diode, so that the antenna has a status indication function.

[0025] Secondly, through the cooperation of the LED driving circuit, the first isolation circuit and the second isolation circuit, the radio frequency signal and the DC signal are multiplexed on the same coaxial feed line, so that the original function of transmitting and receiving electromagnetic waves on the antenna is not affected by the DC signal, while the LED located on the antenna can be driven at the same time. The two do not interfere with each other and can be carried out synchronously.

[0026] Furthermore, the short-circuit protection circuit can prevent the LNB from burning out due to incorrect antenna connection, thus improving the reliability and safety of the LNB and extending its service life.

[0027] Furthermore, by observing the brightness or flickering of the LED, one can determine whether the antenna is properly connected, thereby avoiding damage to the LNB caused by prolonged use of a damaged antenna or coaxial connector, and extending the lifespan of the LNB.

[0077] The LED driving circuit 43 and the radio frequency circuit 44 are respectively connected to the second isolation circuit 42, which is connected to the first oscillator 21 and the second oscillator 22. In this embodiment, the second isolation circuit 42 is connected to the first oscillator 21 and the second oscillator 22 via a coaxial connector 60 and a coaxial feed line 50.

[0078] Preferably, the second oscillator 22 includes an upper oscillator 221 and a lower oscillator 222, wherein the upper oscillator 221 is disposed on the upper surface of the substrate 10 and the upper oscillator 221 is connected to the lower oscillator 222;

[0079] The lower oscillator 222 is disposed on the lower surface of the substrate 10, and the other end of the first capacitor 412 and the negative terminal of the light-emitting diode 30 are electrically connected to the lower oscillator 222.

[0080] The substrate 10 is provided with a first feed hole 11 and a second feed hole 12 in the vertical direction. The first oscillator 21 and the upper oscillator 221 both extend along the length direction of the substrate 10. The left section of the first oscillator 21 extends forward and backward to form a first front connection part 211 and a first rear connection part 212, respectively. The first front connection part 211 and the first rear connection part 212 are respectively connected to one end of the corresponding first inductor 411.

[0081] The coaxial feed line 50 has an inner conductor 51 and an outer conductor 52 sleeved outside the inner conductor 51. The inner conductor 51 passes through the first feed line hole 11 and is connected to the first oscillator 21.

[0083] The strip extension 224 extends along the length of the substrate 10. The right end of the strip extension 224 is integrally connected to the ring portion 223. The left section of the strip extension 224 passes through the second feed hole 12 via the column extension 228 and is connected to the upper vibrator 221.

[0084] In this embodiment, a protective bracket is also included. The protective bracket includes a base 23 and a cover plate 24 that is detachably connected to the base 23. The cover plate 24 has a cavity 241 with an opening at the lower end, an opening at the left end, and an opening at the right end. The light-emitting surface of the light-emitting diode 30 faces upward, and the cover plate 24 is provided with a light guide portion 242 corresponding to the light-emitting surface of the light-emitting diode 30.

[0085] The base 23 is provided with a substrate mounting position 231 for mounting the substrate 10. Preferably, the base 23 is provided with a plurality of hollow support protrusions 232, and all the hollow support protrusions 232 together form the substrate mounting position 231.

[0086] The cover plate 24 and the base 23 are connected by a snap-fit ​​mechanism. The substrate 10 is mounted on the foundation and located within the cavity 241. The base 23 has a clearance hole 233 corresponding to the coaxial feed line 50. The lower end of the base 23 extends downwards from the periphery of the clearance hole 233 to form an annular portion 234. The upper end of the coaxial feed line 50 passes through the annular portion 234 and the clearance hole 233 in sequence to connect to the substrate 10.

[0087] In this embodiment, a short-circuit protection circuit 46 is also included, and the light-emitting diode driving circuit 43 is connected to the second isolation circuit 42 through the short-circuit protection circuit 46.

[0088] Preferably, such as Figure 9 As shown, the short-circuit protection circuit 46 is composed of a chip U4 with model number PW2601 and its peripheral circuits.

[0089] A high-frequency head (HF head) includes an antenna, a HF head main control circuit 45, and a power management circuit for power supply. The antenna is the antenna with a light-emitting diode (LED) 30. The HF head main control circuit 45 is connected to an LED driving circuit 43 and an radio frequency (RF) circuit 44.

[0090] Preferably, such as Figure 10 As shown, the power management circuit consists of chip U3 and its peripheral circuits. The radio frequency circuit 44 consists of chip U1 (model SX1280) and its peripheral circuits, and chip RF1 (model SE24361) and its peripheral circuits. The high-frequency head main control circuit 45 consists of chip U2 (model ESP32-WROOM) and its peripheral circuits.

[0091] The second isolation circuit 42 includes a second inductor L8 and a second capacitor C39;

[0092] One end of the second inductor L8 is connected to one end of the second capacitor C39 and the short-circuit protection circuit 46, respectively. The other end of the second capacitor C39 is grounded and connected to the coaxial connector 60. The other end of the second inductor L8 is connected to the radio frequency circuit 44 and the coaxial connector 60, respectively.

[0093] In this embodiment, the short-circuit protection circuit 46, the second isolation circuit 42, the light-emitting diode driving circuit 43, and the radio frequency circuit 44 are all disposed on the tuner.

[0094] For DC signals, antennas have two structures: short-circuit and open-circuit. When a short-circuit antenna is connected to the LNB, the DC signal output by the LED driver circuit 43 will be short-circuited, potentially burning out the LNB. This embodiment prevents this from happening. Through the short-circuit protection circuit 46, if the external antenna is short-circuited, overcurrent protection is implemented through the PW2601 chip, limiting the maximum output current.

[0095] A remote control includes the aforementioned high-frequency head (LNB). The remote control is capable of sending remote control information to the LNB and also reading remote sensing information returned by the LNB.

[0096] In a communication system, the antenna is a radio frequency (RF) device that transmits and receives electromagnetic waves, driven by RF signals; while the light-emitting diode (LED) 30 is driven by a DC signal. Since RF signals and DC signals differ significantly in their frequencies, the antenna and LED 30 can share the same coaxial feed line 50 without interfering with each other, through the first isolation circuit 41 and the second isolation circuit 42. That is, the electromagnetic wave signals transmitted and received by the antenna are transmitted through the coaxial feed line 50, and the control signals of the LED 30 are also transmitted through the coaxial feed line 50. Technically, the RF signal and the DC signal multiplex the same coaxial feed line 50.

[0097] like Figure 13 As shown, the path of the radio frequency signal is as follows: the radio frequency signal output by the main control circuit 45 of the high frequency head passes through the radio frequency circuit 44, the second isolation circuit 42, the coaxial connector 60, and the coaxial feeder 50 in sequence and is then radiated out onto the first oscillator 21 and the second oscillator 22.

[0098] like Figure 12 As shown, the DC signal path is as follows: the DC signal output by the high-frequency head main control circuit 45 passes through the LED driving circuit 43, short-circuit protection circuit 46, second isolation circuit 42, coaxial connector 60, coaxial feed line 50, first oscillator 21 and first isolation circuit 41 in sequence and is output to the LED 30.

[0099] Since the LED 30 is driven by a DC signal, the connection between the antenna and the LNB can be determined by checking the brightness or flickering of the LED 30, thereby avoiding damage to the LNB caused by prolonged use of a damaged antenna or coaxial connector 60.

[0100] If the brightness or flickering of LED 30 is normal, it indicates that the antenna and LNB are connected well.

[0101] If the brightness of LED 30 dims or flickers abnormally, it indicates that the connection between the antenna and the LNB is not good, and further inspection is needed to check whether the coaxial connector 60 or the coaxial feeder 50 is damaged.

[0102] The key design feature of this invention is that it integrates the light-emitting diode (LED) onto the antenna through the cooperation of a first isolation circuit and an LED, thereby enabling the antenna to have a status indication function.

[0103] Secondly, through the cooperation of the LED driving circuit, the first isolation circuit and the second isolation circuit, the radio frequency signal and the DC signal are multiplexed on the same coaxial feed line, so that the original function of transmitting and receiving electromagnetic waves on the antenna is not affected by the DC signal, while the LED located on the antenna can be driven at the same time. The two do not interfere with each other and can be carried out synchronously.

[0104] Furthermore, the short-circuit protection circuit can prevent the LNB from burning out due to incorrect antenna connection, thus improving the reliability and safety of the LNB and extending its service life.

[0105] Furthermore, by observing the brightness or flickering of the LED, one can determine whether the antenna is properly connected, thereby avoiding damage to the LNB caused by prolonged use of a damaged antenna or coaxial connector, and extending the lifespan of the LNB.

[0106] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
