A reflector is a device that redirects or reflects light in a specific direction. It typically consists of a reflective surface, such as a mirror or metallic coating, that efficiently bounces light back towards its source or towards a desired target. Reflectors are commonly used in various applications, including lighting fixtures, optical systems, photography, and road signs, to enhance visibility and improve the efficiency of light distribution. They play a crucial role in focusing and redirecting light, maximizing its utility and ensuring effective illumination.
