Wide-angle optical design of LED tripod warning sign

The wide-angle optical design of LED tripod warning sign is an important technical link to ensure that it can be clearly identified at various viewing angles. This design is not only related to traffic safety, but also involves multiple fields such as optics, material science and industrial design.
Design principles and goals
Full-angle visibility: Ensure that the LED tripod warning sign has good visibility in both horizontal and vertical directions, covering all angles that the driver may observe.
Brightness uniformity: Through optical design, the brightness distribution on the surface of the sign is uniform to avoid visual discomfort and recognition difficulties caused by local overbrightness or overdarkness.
Anti-glare: Use special optical materials and design methods to reduce glare caused by direct and reflected light, and improve visibility at night and in bad weather conditions.
Optical design points
LED light source layout: Reasonably arrange LED lamp beads, adopt high-density and uniform distribution to ensure that light is evenly radiated to the entire sign surface. Use high-brightness, low-energy LED chips to improve luminous efficiency and brightness level.
Optical lens design: Equipped with a special optical lens, the light emitted by the LED is shaped and diffused through optical principles such as refraction and reflection to form a uniform light spot with a wide viewing angle. The lens surface can be processed with microstructures, such as microprisms, microlens arrays, etc., to further improve light distribution and visual effects.
Multilayer optical film: Multilayer optical films, such as brightening films and diffusion films, are embedded inside the logo to enhance the penetration and scattering effect of light, improve the visual distance and brightness uniformity. These optical films can also protect LED light sources, prevent ultraviolet erosion and extend service life.
Anti-glare treatment: Special optical coatings or structures are used to reduce glare caused by direct light and reflection. By adjusting the light source angle and lens design, the light is mainly radiated in the direction of the driver's line of sight to avoid interference in other directions.
