[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] The purpose of this invention is to provide an RGB matrix independent light module module that, without affecting display quality, effectively reduces the number of LEDs, lowers power consumption, improves heat dissipation performance, and enhances the flexibility and scalability of the module structure, achieving a balance between energy saving, cost reduction, and image quality improvement.
[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] Figure 1 This is a schematic diagram of the module structure provided in the embodiment of the present utility model, as shown below. Figure 1 As shown, this utility model provides an RGB matrix independent optical module module, including:
[0030] (1) Side-emitting direct-down LED bead 1
[0031] like Figure 2 As shown, the LED bead 1 includes at least two independent LED slots, each containing R, G, and B three-color LED chips to generate light sources of different colors. The two LED slots are physically isolated by an internal reflective wall, which is an L-shaped structure used to reflect and guide the light emitted by the LED chips in the LED slots toward a lateral light path in a set direction. The light is expanded through refraction, while preventing interference between the halos of different LED slots, thereby improving the image clarity and color contrast.
[0032] The two LED slots in each LED bead 1 can be driven and controlled independently. The control chip distributes the driving current and signal to control the corresponding RGB LED chips respectively, so as to realize the RGB screen zone control effect of the left and right areas, thereby enhancing the image's sense of layering and color changes.
[0033] (2) Miniature light guide lens 2
[0034] like Figure 3 As shown, the miniature light-guiding lens 2 is mounted directly above the aforementioned LED bead 1 and is fixedly connected to the module housing or substrate via a transparent or semi-transparent support structure. This lens is made of a highly light-guiding material, such as silicone or acrylic, and features high light transmittance, ease of molding, and high temperature resistance.
[0035] The lower surface of the miniature light-guiding lens 2 is provided with a light-guiding groove, which is used to receive the light energy emitted from the side by the lamp bead 1 and guide it into the lens cavity to ensure that the light is evenly distributed in the lens area and avoid uneven display problems such as bright spots and dark areas; the light-guiding groove can be a strip structure or a ring structure, preferably designed according to the position of the lamp bead 1 to match the lens structure shape.
[0036] The upper surface of the lens is provided with optical microstructures, which can be convex, concave, Fresnel plane, or geometric structure. By adjusting the angle and direction of the emitted light, the light energy can be focused or diffused, thereby improving the overall brightness and color reproduction of the module and optimizing the display effect.
[0037] The miniature light guide lens 2 is made of materials with high light transmittance, high light guiding, easy molding, high temperature resistance, and anti-aging properties, such as silicone and acrylic. This miniature light guide lens 2 can be realized through injection molding, pressing, and other processes. In addition, the surface optical microstructure of the miniature light guide lens 2 can also be formed in one step by injection molding and pressing, or even completed by secondary surface coating and bonding after molding. The light energy emitted by the side-emitting direct-down LED bead 1 is transmitted into the lens body through the light guide groove. The silicone and acrylic materials themselves have light guiding functions, which can make the light transmitted by the LED bead 1 fill the lens body. The upper surface of the lens is designed with optical lens microstructures. These structures are convex, concave, Fresnel plane, and multi-geometric structure types, which can appropriately improve the brightness, distribute the effective light output angle, and reflect the most original color emitted by the LED bead 1, so as to form an RGB matrix independent light module module.
[0038] (3) Raster partitioning slot 3
[0039] like Figure 4 As shown, the grating partitioning slot 3 is disposed at the bottom and side of the miniature light guide lens 2, and its structure includes several light-blocking sections for partitioning the light emitted by different lamp beads 1. The inner wall of each light-blocking section is covered with a reflective material layer, which can be made of materials such as metal reflective film, high reflective film material, and nano-coating.
[0040] The grating partition slot 3 not only has basic optical isolation function to prevent optical crosstalk between adjacent LED beads 1, but also has light energy convergence function. Through the combined action of the reflector wall and the partition slot, some of the light energy that may have been lost in the conversion process can be reused, thereby improving light efficiency and reducing energy consumption.
[0041] The grating partition groove 3 can be joined by surface bonding, embedded injection molding, or any other method that can be used. It can even be directly coated on the bottom and side layers of the micro light guide lens 2. The grating partition groove 3 not only has the effect of "light blocking" but also has the effect of "converging" light energy, so that the energy "lost" in the energy conversion process can be converged and reused to achieve energy saving benefits.
[0042] Figure 5 This is a schematic diagram of the modular assembly method provided in this embodiment of the utility model. Multiple independent RGB matrix light module units can be mechanically spliced together through the positioning buckles at the bottom and the positioning slots at the top, realizing a modular matrix layout. Conductive pins and sockets are provided on the side of the module, which automatically completes the parallel connection of power supply and control signals during splicing. All LED beads 1 receive control signals uniformly through the control chip and perform RGB lighting control according to the set driving sequence.
[0043] Specifically, this RGB matrix independent light module unit utilizes a bottom-mounted snap-fit structure and a top-mounted slot structure to allow multiple module units to be arranged in a matrix, row by row and column by column, horizontally and vertically. Each light module unit has standardized mounting holes at its bottom, allowing it to be fixed to a unified PCB board using screws or snap-fit mechanisms. The PCB board contains power supply circuits and control pins corresponding to each light module unit, providing centralized power supply and unified control signals to multiple splicing modules. The conductive connection terminals of the module units connect to the gold finger interfaces or pads on the PCB board via plug-in connections, ensuring stable signal transmission between modules and facilitating replacement and maintenance. The module structure design features industry-standard dimensions and interface specifications, supporting both independent use of small-sized display units and splicing to construct large-sized high-definition displays.
[0044] This embodiment utilizes the characteristics of a "large-angle LED bracket" to achieve separate operation of the three RGB LED chips, thereby achieving a color mixing effect. The light energy emitted by LED bead 1 is then distributed throughout the lens cavity via the "light guide groove" in the micro light guide lens 2. Furthermore, the reflective effect of the grating partition groove 3 itself is used to change the direction of light travel (upward) through refraction and reflection. While changing the direction of light travel upward, the optical microstructure design on the surface of the micro light guide microlens optimizes the light emission effect.
[0045] By utilizing the matrix arrangement principle of "LEGO bricks" and combining it with three main elements, namely "miniature light guide lens 2", "grating partitioning slot 3", and "side-emitting direct-lit LED bead 1", an "RGB matrix independent light module module" has been developed. This module can improve the picture quality without affecting the display screen's image quality, and can also achieve arbitrary matrix arrangement. It can effectively improve all the industry's pressing problems mentioned at the beginning, thereby effectively achieving cost reduction and energy-saving green products.
[0046] like Figure 6 and Figure 7 As shown, since LED chips with "RGB" three color elements are implanted in each of the lamp slots in this embodiment, a multi-color display effect is achieved; and due to the structure of the lamp bead 1, the two lamp slots can be controlled separately, resulting in a more "layered" display of the colors in the displayed image.
[0047] Through the above structural design, this utility model can not only reduce the number of LED beads, reduce power consumption and heat generation while maintaining high image quality, but also realize flexible module assembly and color area control, which has good practicality and promotion prospects.
[0048] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0049] This document uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
