Description

An LED light-emitting antenna structure and device Technical Field

[0001] This utility model relates to an antenna structure, specifically an LED light-emitting antenna structure, and also to an LED light-emitting antenna device. Background Technology

[0002] Chinese patent document CN203553326U, entitled "Light-emitting Antenna Structure," discloses a light-emitting antenna structure. The main structure includes a base, a current-guiding group on the base, a transceiver group on the current-guiding group, a light-emitting group on a metal wire of the transceiver group, and a light-transmitting outer tube inserted into the transceiver group. The transceiver group primarily uses light-emitting diodes (LEDs) for illumination, which are connected to the metal wire via wires.

[0003] The LEDs described above draw power from the metal wire. However, when the metal wire operates as an antenna, it only generates a small current, which is insufficient to provide adequate power. Furthermore, the metal wire is elongated and cylindrical, making it difficult to accommodate a large number of LEDs, resulting in low overall brightness. Additionally, placing LEDs across the metal wire can also negatively impact the performance of the metal wire as an antenna for transmitting radio waves. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an LED light-emitting antenna structure that offers high luminous brightness and minimal impact on antenna performance.

[0005] The technical solution adopted by this utility model to solve the problem is:

[0006] An LED light-emitting antenna structure includes a circuit board, an antenna element, and multiple LED beads. The antenna element is flat and laid on the front side of the circuit board. The feed point of the antenna element is located on the circuit board below the center line of the antenna element. The multiple LED beads are arranged on the circuit board along the edge of the front projection of the antenna element. The connecting wires between the multiple LED beads are arranged on the back side of the circuit board. The circuit board is provided with LED bead control connection points for external devices to power and control the LED beads.

[0007] In a further improvement, the circuit board is a rectangular strip, the antenna vibrator covers the upper part of the circuit board, and the antenna vibrator has a hollow mounting position for installing LED beads.

[0008] In a further improvement, the edge contour shape of the portion of the antenna element below the feed point is Y-shaped.

[0009] As a further improvement, the connecting wires of the LED beads located on the back of the antenna vibrator are routed along the edge of the circuit board.

[0010] Further improvements include ensuring that the ratio of the width of the LED bead to the width of the antenna vibrator is no greater than 1 / 5.

[0011] In a further improvement, the multiple LED beads are divided into two groups, one group is located on the front of the circuit board, and the other group is located on the back of the circuit board.

[0012] Further improvements include placing the LED beads on the front of the circuit board on one side of the circuit board, and placing the LED beads on the back of the circuit board on the opposite side of the circuit board.

[0013] In a further improvement, each group of LED beads is divided into two subgroups, with each subgroup located on the left and right sides of the circuit board.

[0014] An LED light-emitting antenna device includes a connecting base and a diffuser tube disposed on the connecting base. The connecting base is provided with an antenna coaxial line and a connecting wire for powering and controlling LED beads. It also includes a light-emitting antenna with the LED light-emitting antenna structure as described in any of the above claims. The light-emitting antenna is placed inside the diffuser tube. The end of the antenna coaxial line is electrically connected to the feed point of the antenna element. The connecting wire is electrically connected to the LED bead control connection point.

[0015] In a further improvement, the diffuser tube includes an inner diffuser tube and an outer diffuser tube, with the light-emitting antenna placed inside the inner diffuser tube.

[0016] The beneficial effects of this utility model are as follows: This utility model sets an antenna vibrator and multiple LED beads on a circuit board. The LED beads are arranged along the edge of the front projection of the antenna vibrator, which provides sufficient space to arrange a large number of LED beads and reduces the impact on the performance of the antenna vibrator. In addition, the circuit board is provided with LED bead control connection points, so that external devices can supply power and control the LED beads individually during use, ensuring that the LED beads have sufficient power supply and strong luminous brightness.

[0023] The following will provide a clear and complete description of the concept, specific structure, and technical effects of this invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this invention. The various technical features of this invention can be combined interactively without contradicting each other.

[0024] Referring to Figures 1 to 6, the LED antenna structure includes a circuit board 1, an antenna element 2, and multiple LED beads 3. The circuit board 1 is a PCB or FPC board, serving as the substrate for supporting the antenna element 2 and the LED beads 3. The antenna element 2 is flat and is laid on the front of the circuit board 1. The feed point 21 of the antenna element 2 is located on the circuit board 1 below the centerline of the antenna element 2.

[0025] Multiple LED beads 3 are arranged on the circuit board 1 along the edge of the front projection of the antenna element 2. These LED beads 3 are divided into two groups, one group is located on the front of the circuit board 1, and the other group is located on the back of the circuit board 1. From the front projection, these two groups of LED beads 3 are arranged along the edge of the antenna element 2, which can reduce the impact on the antenna performance of the antenna element 2, and at the same time, there is sufficient arrangement space along the edge of the antenna element 2.

[0026] The connecting wires between these LED beads 3 are located on the back of the circuit board 1, and the circuit board 1 has reserved LED bead control connection points 11, including power connection points and control signal connection points, for external devices to provide separate power supply and control for the LED beads 3. Separating the power connections of the antenna vibrator 2 and the LED beads 3 avoids mutual interference between them. Furthermore, LED beads 3 are selected with driver chips, which facilitates the realization of diverse light effects and reduces the use of surrounding components. The ratio of the width of the LED bead 3 to the width of the antenna vibrator 2 is no greater than 1 / 5, ensuring that the width of the LED bead 3 is not too large, thereby reducing the impact on antenna performance.

[0027] In one embodiment, as shown in Figures 4 and 5, a group of LED beads 3 on the front of the circuit board 1 are concentrated on the left side of the circuit board 1, while another group of LED beads 3 on the front of the circuit board 1 are concentrated on the right side of the circuit board 1. Of course, the front LED beads 3 can also be located on the right side of the circuit board 1, while the back LED beads 3 can be located on the left side of the circuit board 1. The two groups of LED beads 3 are located on opposite sides, which facilitates the arrangement of the LED beads 3.

[0028] In one embodiment, each group of LED beads 3 is divided into two subgroups, as shown in Figure 6. The LED beads 3 located on the front of the circuit board 1 are divided into two subgroups, respectively located on the left and right sides of the front of the circuit board 1; the LED beads 3 located on the back of the circuit board 1 are also divided into two subgroups, similarly located on the left and right sides of the back of the circuit board 1. This arrangement of LED beads 3 allows for the arrangement of a larger number of LED beads, and the presence of LED beads 3 on both the left and right sides results in more uniform light emission.

[0029] In one embodiment, the circuit board 1 is a rectangular strip structure, and the antenna element 2 covers the upper front of the circuit board 1. In this structure, the antenna element 2 has pre-drilled mounting positions 22 for mounting LED beads 3, as shown in Figure 3. If only one set of LED beads 3 is provided on the left side, the antenna element 2 only has mounting positions 22 on the left side; if there are sets of LED beads 3 on both sides, the antenna element 2 has mounting positions 22 on both the left and right sides.

[0030] As shown in Figures 1 and 2, the antenna element 2 is located on the upper part of the circuit board 1. The feed point 21 of the antenna element 2 is located below the center line. The edge contour of the lower part of the antenna element 2 where the feed point 21 is located has a Y-shaped gradient. This gradient structure can effectively avoid the influence of the wiring of the LED beads 3 on the antenna performance. Furthermore, the wiring of the LED beads 3 located on the back of the antenna element 2 runs along the edge of the circuit board 1, so that the antenna elements 2 are coupled together, which optimizes the impedance and increases the bandwidth.

[0031] As shown in Figures 4, 5, and 6, the LED light-emitting antenna device includes a connecting base 4 and a diffuser tube 5. The diffuser tube 5 is fixedly connected to the connecting base 4. The connecting base 4 also has an antenna coaxial line 41 and a connecting wire 42. The antenna adopts the aforementioned LED light-emitting antenna structure. The light-emitting antenna is placed inside the diffuser tube 5. The end of the antenna coaxial line 41 is electrically connected to the feed point 21, transmitting signals to the antenna vibrator 2 through the antenna coaxial line 41. The antenna coaxial line 41 is arranged at the center line of the circuit board 1 to avoid obstructing the light emission of the LED beads 3. The connecting wire 42 is electrically connected to the LED bead control connection point 11. After the connecting base 4 is connected to external equipment, the LED beads 3 can be powered and controlled through the connecting wire 42.

[0032] In a preferred embodiment, as shown in Figures 4 and 5, the diffuser 5 includes an inner diffuser 51 and an outer diffuser 52. The light-emitting antenna is placed inside the inner diffuser 51. The use of a double-layered diffuser 5 makes the light emitted by the LED beads 3 more uniform and the lighting effect better.
