Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting equipment technology, and in particular to a light guide plate system. Background Technology
[0002] A light guide plate is a device that can control the direction of light propagation and enhance the brightness of light. It is usually used to effectively diffuse and concentrate the light from a light source to achieve better lighting effects.
[0003] Light guides primarily function based on the principle of total internal reflection. When light enters the light guide from a light source, if the angle of incidence is greater than the critical angle, the light will undergo total internal reflection within the light guide and propagate along its length. By designing the shape and texture of the light guide, the propagation path and exit direction of the light can be controlled, thereby achieving the desired lighting effect.
[0004] Currently, the structure of light guide plate systems on the market is relatively simple. A light source illuminates the light guide plate to display a pattern, and the pattern can be changed by replacing the light guide plate. However, not only does changing the display pattern require replacing the entire light guide plate, which is costly, but also, because the display pattern is inside the light guide plate and the light source is transparent, the pattern is not clearly displayed after the light guide plate is illuminated.
[0005] Therefore, it is necessary to design a light guide plate system to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a light guide plate system.
[0007] The technical solution of this utility model is: a light guide plate system, including a light source, a light guide plate and a backing plate; the light source is disposed on the top of the light guide plate; the backing plate is disposed on one side of the light guide plate; the backing plate has a pattern.
[0008] The light source includes a PCB board and a number of LED beads evenly distributed along the length of the PCB board.
[0009] The top of the light guide plate is provided with a support platform for positioning the light source.
[0010] The light guide plate is made of a transparent material.
[0011] The liner is made of an opaque material.
[0012] The liner and the light guide plate are detachably connected, and the side of the liner with the pattern is attached to the light guide plate.
[0013] The design pattern is presented on the backing plate by laser engraving or die-cutting.
[0014] By adopting the above technical solution, this utility model has the following beneficial effects: This utility model is provided with a backing plate, and the design pattern is placed on the backing plate. When the light source is lit, the light enters the light guide plate, and part of the light is reflected in the light guide plate to the backing plate, thereby illuminating the design pattern and making the design pattern clearer. When the design pattern needs to be replaced, only the backing plate needs to be replaced, which greatly reduces the replacement cost. Attached Figure Description
[0015] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0016] Figure 1 This is a schematic diagram of the structure of this utility model.
[0017] Figure 2 This is an exploded view of the present invention.
[0018] The labels in the attached diagram are:
[0019] Light source 1, PCB board 1-1, LED beads 1-2, light guide plate 2, support platform 2-1, backing plate 3, decorative pattern 4. Detailed Implementation
[0020] See Figure 1 and Figure 2 The light guide plate system of this embodiment includes a light source 1, a light guide plate 2 and a backing plate 3; the light source 1 is disposed on the top of the light guide plate 2; the backing plate 3 is disposed on one side of the light guide plate 2; the backing plate 3 has a pattern 4.
[0021] The light source 1 includes a PCB board 1-1 and a plurality of LED beads 1-2 evenly distributed along the length of the PCB board 1-1. In this embodiment, through a carefully designed light source structure, namely the LED beads 1-2 evenly distributed along the length of the PCB board 1-1, it is possible to ensure that the light is uniformly and efficiently irradiated onto the light guide plate 2.
[0022] Furthermore, the top of the light guide plate 2 is provided with a support platform 2-1 for positioning the light source 1. The support platform 2-1 on the top of the light guide plate 2 not only provides the light source 1 with a precise positioning function, but also effectively avoids the heat accumulation and light loss problems that may be caused by direct contact between the light source 1 and the light guide plate 2.
[0023] Furthermore, the light guide plate 2 is made of a transparent material, which further enhances the light transmission efficiency, allowing the light to be evenly distributed along the length of the light guide plate 2, effectively avoiding uneven light distribution and energy loss, and improving the overall energy efficiency of the lighting system.
[0024] The liner 3 is made of an opaque material, which can effectively block light from leaking from the side, further improving the utilization rate of light and the lighting effect.
[0025] Furthermore, the liner 3 is detachably connected to the light guide plate 2, and the side of the liner 3 with the pattern 4 is attached to the light guide plate 2. The liner 3 and the light guide plate 2 are detachably connected. This design not only makes it easy for users to replace the liner 3 with different patterns according to their needs, realizing quick switching of lighting effects, but also facilitates the daily maintenance and cleaning of the system. When the liner 3 or the light guide plate 2 is damaged, users can easily replace it, reducing maintenance costs and extending the service life of the system.
[0026] Furthermore, the design pattern 4 is presented on the backing plate 3 by laser engraving or die-cutting.
[0027] The light guide plate system proposed in this embodiment shows significant advantages in terms of light energy transmission efficiency, customized lighting effects, ease of maintenance and replacement, and optimized structural design, and has broad application prospects and market value.
[0028] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
