Description

Technology Field

[0001] The present invention relates to an LED lighting device utilizing a fabric diffusion effect, which utilizes the light diffusion characteristics of a fabric to uniformly disperse light generated from an LED element and simultaneously achieves aesthetic design and functionality. Background Technology

[0002] Recently, LED lighting has achieved rapid growth in the lighting market due to advantages such as energy efficiency, long lifespan, and low heat generation. However, due to the direct emission characteristics of LEDs, the light distribution is localized and exhibits strong linearity, making it difficult to achieve uniform light dispersion and soft diffusion effects. This issue can lead to glare, uneven lighting distribution, and user discomfort during lighting design, and also presents limitations in terms of aesthetic design.

[0003] Conventional LED lighting systems have utilized acrylic, polycarbonate, glass fiber, and other transparent materials as diffusers to diffuse light. However, these materials come with drawbacks, such as high manufacturing costs, difficulty in processing, and a lack of design flexibility. Additionally, while some systems attempted to disperse light by applying internal fine particles or coatings, there were limitations in simultaneously achieving the desired uniformity and aesthetic effects.

[0004] In recent years, the optical properties of fabric materials have been attracting attention in the lighting field. Fabrics possess the advantage of maximizing light scattering and diffusion effects thanks to the fine structure and porous characteristics of their fibers. In particular, the light scattering characteristics resulting from the weave and material of the fibers are highly effective in softly and uniformly dispersing LED light. Furthermore, fabrics can be manufactured in various textures, colors, thicknesses, and patterns, offering excellent flexibility in terms of design.

[0005] In conventional LED lighting systems, implementing customized lighting solutions has been difficult due to the rigid structure of materials used as diffusers and limited design options. Additionally, there were issues with increased production costs resulting from heat generation, durability problems, and the complexity of the manufacturing process. Accordingly, this invention aims to optimize the light distribution of LED lighting by utilizing the natural diffusion effect of fabric, while simultaneously achieving simplification of the manufacturing process and cost reduction.

[0010] The LED lighting utilizing a fabric diffusion effect according to the present invention comprises the steps of: configuring an LED lighting module (S1); configuring a fabric diffusion layer (S2); combining the LED lighting module and the fabric diffusion layer (S3); and configuring an electronic control and thermal management system (S4).

[0011] The LED lighting utilizing the fabric diffusion effect according to the present invention includes the step (S1) of configuring an LED lighting module.

[0012] It is designed to be driven through an integrated circuit by arranging multiple high-efficiency blue and white LED elements. The LED elements are arranged at intervals of 0.5 mm, and to minimize heat generation and light concentration issues, they are placed at regular intervals rather than in a high-density arrangement. Transparent acrylic or polycarbonate materials are attached to the LED elements to control the focus and diffusion of light.

[0013] The substrate uses an aluminum or ceramic substrate with excellent thermal conductivity and serves to dissipate heat by making direct contact with the LED element. The substrate thickness is 1 to 2 mm, and an aluminum oxide coating is applied to the surface finish to enhance durability. An integrated circuit (IC) for power supply and brightness control of the LED element is mounted directly on the substrate. A reflector with an aluminum thin film or silver coating is attached to the bottom of the substrate to reflect a portion of the light emitted from the LED element, thereby maximizing light efficiency.

[0014] The LED lighting utilizing the fabric diffusion effect according to the present invention includes a step (S2) of forming a fabric diffusion layer.

[0015] For the fabric material, materials with excellent light scattering properties are selected from fibers such as cotton, polyester, and nylon, and cotton / polyester blended composite fibers may be utilized if necessary.

[0016] The selected fabric material undergoes a hot water washing and drying process at 80°C for 30 minutes to remove impurities and ensure fiber spacing and weave uniformity. After hot water washing and drying, patterns such as triangles, hexagons, and circles are designed using CAD software, and rubber or silicone-based micro-patterns are implemented on the fabric surface using a pre-prepared pattern mold.

[0017] To reinforce the edges of the fabric diffusion layer and the joint area with the LED module, heat-resistant polyester or nylon thread is used for sewing. The sewing interval is set to 2 to 3 mm, and the sewing method combines straight sewing and overlock sewing.

[0018] The LED lighting utilizing the fabric diffusion effect according to the present invention includes the step (S3) of combining an LED lighting module and a fabric diffusion layer.

[0019] A heat-pressing process is applied between the transparent cover located on the top of the LED module and the fabric diffusion layer to initially bond the two components. The bonding conditions are adjusted considering the characteristics of the fabric and bonding materials, and bonding strength is secured through cooling after heat-pressing. During heat-pressing, the fabric diffusion layer is stably attached to the LED module at a temperature of 140 to 160°C, taking into account the temperature of the LED module and the heat resistance of the fabric material. After the initial heat-pressing bond, sewing and bonding processes are additionally performed to reinforce durability and maximize the bonding strength between the LED module and the fabric diffusion layer. A metal or reinforced plastic frame is inserted at the joint to improve mechanical strength and ensure durability against vibration and external impact. The frame can be made of aluminum or reinforced plastic.

[0020] The LED lighting utilizing the fabric diffusion effect according to the present invention includes the step (S4) of configuring an electronic control and thermal management system.

[0021] An MCU-based control system is applied by adopting a PWM control method to enable stable power supply and brightness adjustment for LED elements; temperature sensors are installed inside the LED module and at the connection point to perform real-time temperature monitoring; an algorithm is implemented to automatically adjust LED brightness by detecting ambient light through an external light sensor; and the completed LED lighting device undergoes quality inspection regarding optical performance, electrical safety, mechanical durability, and aesthetic design elements.
