Description

Technical Field

[0001] This invention relates to the technical field of lighting fixtures, and more particularly to a method for processing optical textures on a light guide plate. Background Technology

[0002] Light guide plates are an important component of lighting fixtures. The optical textures on the light guide plate alter the direction of light propagation, ensuring the light hits the diffuser plate and forms a uniform light-emitting surface. The optical textures on the light guide plate are crucial to the final optical effect of the product. Generally, the optical textures on the light guide plate are created by laser processing or high-precision CNC (Computerized Numerical Control) to produce a dotted shape. The uniformity of the light-emitting surface is controlled by adjusting the density and size of the dots. Laser or CNC processing of the dots has a long processing time and high cost, and subsequent modifications are also difficult.

[0003] Another technique is etching-based texturing. This technique uses a film with a customized etching pattern, which is then attached to the mold surface. An etching solution is sprayed onto the film surface, and after a period of time, the designed texture forms on the mold surface. The texture processing area is controlled by the shape and size of the film, the texture shape by the film pattern, and the texture depth by the time the etching solution is left on. Due to limitations in film attachment, conventional etching techniques struggle to process deep grooves and holes. Furthermore, the film needs to be customized according to the processing area and pattern, resulting in higher processing costs.

[0004] Therefore, how to provide a convenient and less restrictive optical texture processing method for light guide plates is a technical problem to be solved. Summary of the Invention

[0005] To address the technical problems of complex and limited optical texture processing of light guide plates in existing technologies, this invention proposes a method for optical texture processing of light guide plates and an ambient light.

[0006] The optical texture processing method for light guide plates proposed in this invention includes:

[0007] Step S1: On the side of the light guide plate that needs to be processed with optical texture, apply a protective paint with anti-etching effect by spraying, so that the protective paint is distributed on the surface of the light guide plate in the form of discrete particles;

[0008] Step S2: Dry and cure the protective paint particles on the surface of the light guide plate;

[0009] Step S3: Immerse the side of the light guide plate that needs to be processed with optical texture into the etching solution and let it stand for a predetermined time before taking it out, so that the area not covered by the protective paint particles forms an etched texture.

[0010] Step S4: Clean the light guide plate to remove the protective paint particles and obtain a light guide plate with optical texture.

[0011] Furthermore, prior to step S1, the method includes: applying protective stickers to the periphery of the light guide plate that does not require optical texture processing and to the opposite side of the light guide plate to provide shielding protection.

[0012] Furthermore, the protective paint is an acid-resistant ink.

[0013] Furthermore, in step S2, the drying method for the protective paint particles is natural air drying or heat drying.

[0014] Furthermore, in step S4, organic solvents are first used to clean and protect the paint particles, followed by rinsing with water.

[0015] The ambient light proposed in this invention includes a bracket, a light guide plate, and a light source. The optical texture of the light guide plate is made using the optical texture processing method of the light guide plate described above.

[0016] Furthermore, it also includes a diffusion plate.

[0017] This invention enables the processing of deep grooves and holes that cannot be processed by general etching techniques by spraying protective paint on the surface of the light guide plate. At the same time, it eliminates the need for custom film, resulting in lower costs and shorter processing cycles. Attached Figure Description

[0020] Figure 2 This is a schematic diagram of a lamp structure according to an embodiment of the present invention. Detailed Implementation

[0021] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the invention, and does not imply that every embodiment of the invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0023] The optical texture processing method for the light guide plate of the present invention, such as... Figure 1 As shown, in a basic embodiment, the following processing steps are included.

[0024] Step S1: Spray protective paint particles.

[0025] This step involves selecting the light guide plate to be processed and spraying an anti-etching protective paint onto the side where optical textures are desired. Existing acid-resistant inks can be used. The paint is sprayed onto the mold surface using a spray gun and dried to form protective paint particles. By controlling the spray gun nozzle structure, spraying time, and spraying distance, the protective paint sprayed onto the light guide plate surface is made into randomly distributed particles, thus providing masking conditions for subsequent etching to form irregular optical textures.

[0026] Step S2: Dry and protect the paint particles.

[0027] After the spraying is completed, the protective paint particles on the surface of the light guide plate are dried to ensure that the protective paint particles adhere firmly to the surface of the light guide plate.

[0028] In practice, different drying methods can be selected according to environmental conditions. When the ambient temperature is high, natural air drying can be used, or when the ambient temperature is low, heating drying can be used to ensure that the paint particles do not flow or fall off during subsequent etching. For example, at room temperature or a high ambient temperature, air dry until the ink is dry and not sticky. When the ambient temperature is low, an oven can be used to bake at a controlled temperature of 40-45℃ for about 10-15 minutes.

[0029] Step S3, etching process.

[0030] After the light guide plate has been dried, immerse the side that needs to be processed with optical texture into the etching solution and let it stand for a predetermined time before removing it.

[0031] In this embodiment, the etching solution is a conventional etching solution. During the etching process, the areas of the light guide plate surface not covered by protective paint particles come into direct contact with the etching solution and undergo an etching reaction, thereby forming an etched texture with varying unevenness on the surface of the light guide plate; while the areas covered by protective paint particles are shielded and do not undergo etching. By controlling the settling time of the light guide plate in the etching solution, the depth of the formed optical texture can be adjusted.

[0032] Step S4: Clean and protect the paint particles.

[0033] After etching is completed, the light guide plate is cleaned to remove the protective paint particles adhering to its surface.

[0034] In a preferred embodiment, before step S1, protective stickers can be applied to the periphery of the light guide plate where optical textures are not required and the other side to protect it from being affected during the etching process, thereby achieving precise control over the optical texture processing area.

[0035] The above processing method can form the required optical texture structure on the surface of the light guide plate without the need for custom film. The method is highly adaptable to the surface shape of the light guide plate and can be applied to areas with deep grooves or deep holes. The process is simple, the processing cost is low, and the processing cycle is short.

[0036] like Figure 2 As shown, the ambient light of the present invention includes a bracket 1, a light guide plate 2 and a light source 3. The optical texture of the light guide plate can be made by the optical texture processing method of the light guide plate described above.

[0037] In a further embodiment, the ambient light of the present invention may also include a diffuser plate 4 disposed on the light-emitting side of the light guide plate 2.

[0038] This invention utilizes a protective paint sprayer nozzle to apply protective paint to the mold's surface, creating a designed pattern. The remaining parts of the mold are covered with protective stickers. After the protective paint dries, the etched areas are immersed in a special etching solution for a specific time. The unpainted surface of the mold will then exhibit an etched texture. This protective paint is removed using the special solution, revealing the designed texture. The application of protective stickers allows control over the textured area. The size of the ink particles can be adjusted by controlling the size of the sprayer nozzle mesh. The spraying time can be adjusted to control the ink density, thus controlling the texture density. The etching depth can be controlled by adjusting the mold's immersion time in the etching solution. These control methods allow for the achievement of designed texture density and depth, resulting in different light-guiding effects. Furthermore, this texturing technology can process deep grooves and holes that are inaccessible by conventional etching techniques, while eliminating the need for custom film, thus reducing costs and shortening the processing cycle.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
