The unit includes translucent, tinted or opal sections (1) made preferably from acrylic plastic with the same refractive index as glass and forming a polygon or cylinder. Disposed axially, they are perpendicular to continuous or local concave depressions in the optical sections, aligned with the position and beam emissions of the LEDs. As many printed circuits (10) as required, carry LEDs and resistors only. Held between two symmetrically-ribbed end plates (2, 13) in PVC or rigid plastic, the unit is supplied via a first independent circuit (3) from the mains, or consumes wind- or solar energy. |
