Title:
SIGNALLING DEVICE VISIBLE THROUGHOUT 360� COMPRISING A LIGHT SOURCE COMPOSED OF SEVERAL ELECTROLUMINESCENT DIODES AND SEA BUOY PROVIDED WITH SAID DEVICE
Document Type and Number:
WIPO Patent Application WO/1995/018331
Kind Code:
A1
Abstract:
Signalling device visible throughout 360� comprising a secondary power circuit having, for each diode, a connection area (9), wherein the diodes are located at right angles to said areas. The device is characterized in that the areas (9) for connecting each group of diodes connected electrically in series are, firstly, offset from one another by a reference distance (D), and, secondly, aligned along an axis, known as a series supply line. The device is also characterized in that within a series of series supply lines, the areas (9) for connecting a line are, in relation to the immediately adjacent lines of the same series, offset by a value substantially equal to the ratio of the reference distance divided by the number of lines in the series.
