Abstract (en)

[origin: EP3677829A1] Disclosed are a primary lens (100), a light-emitting assembly, a light-emitting system, and a headlight, which relate to the technical field of optical components. The primary lens (100) comprises a main body portion (110), and the main body portion (110) comprises a first optical surface (111) and a second optical surface (112), wherein a linear focus line (113) is formed on the first optical surface (111), and the height of the first optical surface (111) is gradually reduced from the focus line (113) towards two sides; and the second optical surface (112) comprises a plurality of ridges (114) arranged in parallel, with an extension direction of the ridges (114) being perpendicular to the focus line (113), and the ridges (114) have arc-shaped convex faces. Under the conditions where the focus line (113) extends horizontally and the ridges (114) extend vertically, the primary lens (100) can converge light that is incident on the first optical surface (111) in a vertical direction and diffuse the light in a horizontal direction, thereby satisfying the illumination characteristics of a headlight of a vehicle.
