In cultural and educational LED products, wooden soft light board is commonly used as an auxiliary material for light output in devices such as copying tables, copying boards, and drawing light boards. Its basic function is to diffuse and soften the LED light source, making the distribution of light on the working surface relatively uniform and reducing eye irritation during long-term use.

Taking the copying table as an example, LED light sources are usually arranged inside the equipment. If they directly emit light through the panel, bright spots or uneven brightness may occur. Wooden soft light board is placed between the light source and the working surface, and through the diffuse reflection characteristics of the material, it converts point or linear light sources into surface light, thereby improving the uniformity of illumination on the working surface. For usage scenarios that require long-term desk copying and drawing, the uniformity of lighting directly affects visual comfort.

In terms of material selection, the thickness, density, and surface treatment method of the wooden soft light board will affect the final light output effect. Thick soft light boards have relatively strong shading ability, but their transmittance may decrease; Thin thickness results in better transparency, but may not provide sufficient shading effect on the light source. Therefore, in the design of cultural and educational LED products, it is necessary to match the parameters of the soft light board based on factors such as light source power, layout density, and usage distance.

In addition, wooden materials have certain environmental adaptability and good dimensional stability under temperature and humidity changes, making them suitable for cultural and educational products with certain requirements for flatness. During installation, it is usually necessary to reserve appropriate gaps to cope with the thermal expansion and contraction of materials, and to facilitate later cleaning and maintenance.

Overall, the application of wooden soft light boards in cultural and educational LED products mainly revolves around the uniformity of light output and visual comfort. Through reasonable material selection and structural design, it is possible to balance the user experience and product durability while meeting lighting requirements.
