Abstract
A light projector for signalling high obstacles, having an elongate cylindrical lens, a linear light source in which the light projector has at least two reflectors and at least one of the reflectors is an upper reflector positioned above the horizontal plane of symmetry of the cylindrical lens and below an upper surface of the cylindrical lens, and at least one of the reflectors is a lower reflector positioned below the horizontal plane of symmetry of the cylindrical lens and above a lower surface of the cylindrical lens, the reflectors being configured to interrupt light rays from the light source that are oriented outside the elevation angular sector of the main flat light beam is disclosed.
Claims11
Light projector (6) according to claim 1, in which the upper reflector (29) and/or the lower reflector (28) have/has a reflective upper surface.
Light projector (6) according to claim 1, in which the upper reflector (29) has a reflective lower surface and the lower reflector (28) has an absorbent lower surface.
Light projector (6) according to claim 1, in which each reflector (28, 29) is rectangular in shape and has two longitudinal sides parallel to the horizontal generatrix direction (9) and two transverse sides that are oriented at an elevation angle (s) contained within the predefined elevation angular sector of the main flat light beam (3).
Light projector (6) according to claim 1, in which the directrix curve is substantially trapezoidal in shape with a small base (21), a large base (22) opposite the small base (21) and two sides (11) connecting the small base (21) to the large base (22), the small base (21) of the trapezium being situated facing the light source (16).
Light projector (6) according to claim 1, in which the lower reflector (28) and/or the upper reflector (29) are/is separated from the horizontal plane of symmetry by a distance of less than 25% of the largest vertical dimension of the cylindrical lens (7).
Light signalling beacon (1) comprising a support (19) and multiple projectors (6) according to claim 1 fixed to the support, the projectors (6) being oriented in distinct directions about a vertical axis such that the azimuth angular sectors of the projectors cover 360° about the vertical axis.
