Description

Technical Field

[0001] This application relates to the field of optical lighting technology, and in particular to a composite light distribution module. Background Technology

[0002] With the development of society and the economy, the demand for advertising light boxes is increasing, and the requirements for them are also becoming more stringent. Traditional light distribution modules suffer from problems such as a single light distribution mode and low light efficiency, making it difficult to meet the diverse needs of increasingly thinner light boxes. Although some existing technologies have been improved, they are complex in structure, costly, and lack sufficient adjustment flexibility. Currently, the thickness of advertising light boxes on the market is generally over 6 cm, resulting in high product application costs, large space occupation, and densely packed internal components. Some solutions rely on TV backlight reflection (which has very low light efficiency and requires a high-quality reflective surface) while others use light guide plates (which are too heavy).

[0018] See Figures 1-2 , Figure 1 This is an exploded view of the structure of a composite light distribution module provided in one embodiment of this application. Figure 2This is a schematic diagram of a composite light distribution module according to an embodiment of this application. The composite light distribution module includes a substrate 1, a lens 2, an LED 3, a wire 4, and a housing 5. The upper surface of the substrate 1 is provided with the LED 3 and the lens 2, with the LED 3 located inside the lens 2. The substrate 1 has a silkscreen layer 11, which surrounds the connection between the lens 2 and the substrate 1. The wire 4 is connected to both ends of the substrate 1. The housing 5 has an accommodating space and is provided with a first opening 51 and a second opening 52. The substrate 1 is disposed in the accommodating space, the protrusion of the lens 2 is disposed at the first opening 51, and the wire 4 passes through the second opening 52.

[0019] In this embodiment, the composite light distribution module integrates multiple light distribution components through innovative structural design, achieving different light distributions and intensity adjustments. The module includes core components such as two sets of basic lenses, LED chip arrangement, and a matching design of white reflective ink on the PCB board. This allows for adjustment of the light diffusion level. The components work collaboratively to adapt to different application scenarios, significantly improving light efficiency and light distribution accuracy. By combining the optics of lens 2 with the PCB surface treatment through three fine-tuning processes, the module meets the requirements for optical lenses 2 in ultra-thin light boxes, reducing the number of lights required and providing a uniform, high-efficiency solution.

[0020] The connection between the lens 2 and the substrate 1 is circular, and the LED bead 3 is located at the center of the circle. The silkscreen layer 11 is disposed around the circular area. The silkscreen layer 11 is a black silkscreen layer 11.

[0021] In this embodiment, the black silkscreen area is precisely planned according to the shape, size, and optical requirements of lens 2. For a circular lens 2, the silkscreen area is typically designed as a concentric ring surrounding lens 2; lens 2 can also be rectangular, and for a rectangular lens 2, a rectangular frame is used. The width of the silkscreen area needs to comprehensively consider factors such as the effective aperture of lens 2, the angle of incidence of light, and the light absorption capacity of silkscreen layer 11. Generally, the width of the silkscreen area should be wide enough to cover the area around lens 2 that may generate reflections, but it should not be too wide to avoid affecting the layout and electrical performance of other components on the PCB board. In addition, the assembly error between lens 2 and PCB board must be considered, and a certain margin must be reserved to ensure that the black silkscreen can effectively reduce the reflection of lens 2 under various assembly conditions.

[0022] The thickness of the screen printing layer 11 ranges from 10 to 25 μm, and the thickness of the screen printing layer 11 gradually increases from the edge of the lens 2 outwards.

[0023] In this embodiment, the thickness of the black silkscreen layer 11 is closely related to its light absorption performance. Generally, a standard black silkscreen thickness (10-25 μm) is sufficient for light blocking. As the thickness of the silkscreen layer 11 increases, its light absorption capacity is enhanced, and the reflection reduction effect is more significant. However, an excessively thick silkscreen layer 11 will prolong the ink drying time, increase the production cycle and cost, and may also lead to printing defects such as ink dripping and uneven edges, affecting the appearance and performance of the PCB board. Therefore, it is necessary to determine a suitable silkscreen layer 11 thickness through experiments and process optimization to ensure light absorption performance while balancing production efficiency and product quality. To further improve the reflection reduction effect, the black silkscreen pattern can be optimized. For example, using microstructure patterns, such as nanoscale grooves or protrusions, can change the light propagation path and increase the scattering and absorption of light within the silkscreen layer 11. Gradient silkscreen patterns can also be designed so that the color or thickness of the silkscreen layer 11 gradually changes from the edge of the lens 2 outwards, better adapting to the incidence of light at different angles and improving the overall light absorption efficiency. When designing silkscreen patterns, optical simulation software should be used for simulation analysis to predict the impact of different patterns on the reflectivity reduction effect and select the optimal design scheme. Furthermore, the black silkscreen design must be compatible with other designs on the PCB board, such as circuit routing and component layout. Avoid covering important electrical connection points, pads, and components with the silkscreen area to prevent affecting the electrical performance and assembly process of the PCB board. Simultaneously, the compatibility of the silkscreen layer 11 with the PCB board surface coating (such as solder mask) must be considered to ensure that there are no chemical reactions or poor adhesion issues between them. During the design phase, close communication and collaboration with PCB design engineers are essential to comprehensively consider optical and electrical performance requirements and achieve optimal overall PCB board design.

[0024] The composite light distribution module lighting technology in this case not only solves the problems of existing technologies and meets the development needs of the advertising industry, but also helps to further achieve more efficient, energy-saving, and environmentally friendly advertising lighting. It is committed to perfectly combining high-brightness LED light sources with composite optical wide-angle lenses, fundamentally improving product efficiency, brightness, emission angle, and reliability, while reducing failure rates and installation and maintenance costs.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
