Abstract:
(EN) Disclosed is a beacon. The beacon includes: a first reflector in which a cross-section perpendicular to the circumference thereof constitutes a parabola, and an inner surface thereof is a parabolic surface obtained by rotating the parabola with respect to the axis of the parabola passing through the focal point of the parabola; a second reflector having a cone shape which has a vertex at the focal point of the parabola, and is flipped over so that the vertex faces in the direction of the parabolic surface, wherein the outer surface of the cone shape is inclined by 45° with respect to the traveling direction of light that is reflected by the parabolic surface; an LED light source coupled to the second reflector so as to be positioned at the vertex of the cone shape; and a power supply unit for supplying power to the LED light source.
(FR) L'invention concerne une balise. La balise comprend : un premier réflecteur dans lequel une section transversale perpendiculaire à la circonférence de celui-ci constitue une parabole et une surface interne de celui-ci est une surface parabolique obtenue par rotation de la parabole par rapport à l'axe de la parabole passant par le point focal de la parabole ; un second réflecteur ayant une forme de cône qui a un sommet au point focal de la parabole et est retourné de telle sorte que le sommet soit face dans la direction de la surface parabolique, la surface extérieure de la forme de cône étant inclinée de 45° par rapport à la direction de déplacement de la lumière qui est réfléchie par la surface parabolique ; une source de lumière à DEL couplée au second réflecteur, de façon à être positionnée au sommet de la forme de cône ; et une unité d'alimentation électrique pour fournir de l'énergie à la source de lumière à DEL.
