Abstract: A multi optical-route Head Up Display (HUD), comprising: at least an image display unit, to generate at least two input images, and project them respectively to a plurality of relay lenses, which adjusts reflection angle of said input signals and then transmits them to a virtual image generation unit, said virtual image generation unit produces a plurality of virtual images, and transmits them to a plurality of transmission mirrors, which reflects said virtual images to form a large area virtual image.

Abstract: A converging illuminant device has a flat illuminant, a reflective layer and an enhancement film. The reflective layer abuts the flat illuminant, is grille-shaped and has multiple longitudinal strips and multiple lateral strips. The enhancement film is securely connected with the reflective layer and has an emissive surface. The emissive surface has multiple free-form curved areas, multiple longitudinal lines and multiple lateral lines. The longitudinal lines respectively align with the longitudinal strips. The lateral lines respectively align with the lateral strips. Because the reflective layer is grille-shaped, light definitely passes through central positions of the free-form curved areas, angles of refraction of the light are small and the light can be effectively converged. Consequently, illuminant efficiency and central luminous intensity are increased.
