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. | 05-09-2013 |
