[0019] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0020] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0022] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0023] The utility model provides an LED display light source, comprising: a plastic bracket 1, a lamp bead 2, and a condenser lens 3. The plastic bracket 1 is provided with a lamp hole 11, the lamp bead 2 is disposed at the bottom of the lamp hole 11, and the sidewalls of the lamp hole 11 are coated with a reflective layer 12. The condenser lens 3 is disposed on the plastic bracket 1 and is located at the top of the lamp hole 11. A driver IC is disposed within the lamp bead 2, and the driver IC is capable of controlling the display of the lamp bead 2, wherein the driver IC serves as a drive controller, which controls the luminous intensity of the lamp bead 2.

[0024] In this application, the plastic bracket 1 has low reflectivity due to its material. Therefore, a reflective layer 12 is applied around the lamp hole 11 to improve reflectivity. The reflective layer 12 is used to focus the light emitted by the lamp beads 2 at the bottom of the lamp hole 11, thereby improving brightness. In addition, a focusing lens 3 is provided at the top of the lamp hole 11 to increase the focusing degree, which can greatly improve the brightness. The brightness of the LED display light source in this application is improved, the power consumption is reduced, and the requirements of outdoor screens with large dot pitch are met. For indoor display screens, while meeting the same brightness, the power consumption can be lower, which is energy-saving and environmentally friendly.

[0025] Furthermore, three lamp beads 2 are disposed within the lamp aperture 11. These three lamp beads 2 are red, green, and blue primary color beads, respectively. The red, green, and blue primary color beads emit red, green, and blue light, respectively. The corresponding driver ICs control the luminous intensity of each red, green, and blue primary color bead, thereby controlling the corresponding LED display light sources to emit light of different colors.

[0026] Furthermore, the side wall of the lamp hole 11 has a taper. The side wall of the lamp hole 11 is set to have a certain taper so that the reflective layer 12 on the side wall of the lamp hole 11 can better gather the light.

[0027] In a preferred embodiment, a pin 13 is provided at the bottom of the plastic support 1, and the pin 13 is electrically connected to the lamp bead 2. The focusing lens 3 is hemispherical in shape.

[0028] Finally, the present invention also provides a display panel, which includes a PCB board and the above-mentioned LED display light source; a plurality of plastic brackets 1 are arranged in an array on the PCB board, and the pins 13 on the plastic brackets 1 are electrically connected to the circuit on the PCB board.

[0029] It should be understood that the above description of the specific embodiments of the present invention is merely for the purpose of illustrating the technical approach and features of the present invention. Its purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly.
