The light guide strip in car lights is a bar-shaped structure made from transparent or semi-transparent materials designed to guide light. Its main function is to distribute the light produced by the car's light source (such as LED lights) evenly across the entire strip. The light guide strip utilizes principles such as refraction, reflection, or total internal reflection to propagate light along the path of the strip, creating a more uniform, precise, and aesthetic lighting effect.
The common materials used for light guide strips are PMMA (Polymethyl methacrylate) and PC (Polycarbonate). PMMA is widely used in high-end car lights due to its excellent optical properties and transparency. PC, on the other hand, offers good impact resistance and high-temperature stability, making it suitable for specialized applications.
The design of light guide strips needs to take into account the position of the light source, light-guiding effect, appearance, and the overall design of the car lights. The surface of the light guide strip can be textured to control light scattering or reflection effects. Designers often use optical simulation software to optimize the performance of the light guide strip.
The injection mold design for light guide strips must take into account the flowability, transparency, and processing characteristics of the chosen materials. Materials like PMMA and PC have relatively poor flowability, requiring precise control over the injection molding process, including temperature, pressure, and time, to ensure a smooth, bubble-free surface.
During the injection molding process, mold temperature is one of the key factors that determine the quality of the final product. Since light guide strips require high transparency, it is crucial to maintain uniform mold temperatures to prevent excessive temperature differences that could cause uneven cooling and affect the optical properties of the final product.
The smoothness of the light guide strip's surface directly affects light transmission, so attention must be paid to the mold surface finish. If special light effects (such as scattering) are required, tiny textures can be designed on the mold surface to control light refraction or reflection.
Because light guide strips are often thin, special care is needed during ejection to avoid scratches or deformation. The mold's ejection angle, ejection force settings, and the use of appropriate release agents are key factors to ensure the integrity and appearance of the product.
The cooling system of the injection mold is critical for ensuring both production efficiency and product quality. Although the thickness of light guide strips is relatively uniform, cooling effects may vary at different locations. Therefore, the mold design should arrange cooling channels effectively to ensure uniform cooling and prevent thermal stress and deformation.
The light guide strip plays a crucial role in automotive lighting by enhancing both the aesthetics and functionality of car lights. When making injection molds for light guide strips, factors such as material selection, mold temperature, surface smoothness, ejection design, and cooling systems must be considered to ensure the production of high-quality light guide strips. These elements determine the optical effect and appearance of the final product.
