ROAD LIGHTING AND DELINEATING APPARATUS
A road lighting and delineating apparatus (1) that can be installed on a supporting structure (10) at an installation height (H) from a road surface (S), includes a central body (2) with an elongated shape, extending in a longitudinal direction (A) and provided with a cavity (23), and a lighting system (4) housed inside the cavity (23) and comprising at least one LED (41) which is mounted on a printed circuit (47), fixed to supporting means (42) positioned inside the cavity (23) and connected to the central body (2), and emits light rays (L); a refractive lens (43) and a reflective optical system (44) associated to the LED (41). The refractive lens (43) shows a substantially elliptic section on a primary plane (PI) and an asymmetric oblong section on a secondary plane (P2) almost perpendicular to the primary plane (PI). The light rays (L), refracted by the refractive lens (43) and reflected by the reflective optical system (44), form a light flux (F) that grazes the road surface (S) when the apparatus (1) is positioned at the installation height (H).
