Definitions

• the present invention relates to a light animation device for creating light visual effects.
• the light animation device comprises at least one light garland supplied by an animator generating alternating current on several supply channels.
• the problem posed that the invention proposes to solve is to reduce the number of wires supplying the light garland, which has the advantage either of being able to reduce the thickness of the light garland, or of reducing the distance between the conductors which make up the light garland, while obtaining the same light effect as the garlands of the prior art.
• diodes are mounted on an even number of outputs supplied from the animator.
• a diode in the direct direction is mounted on one type of output.
• On another type of output is mounted a diode in the opposite direction.
• the two output wires on which a diode in the forward direction and a diode in the reverse direction are joined then in a common supply wire. Between this common supply wire and the neutral wire are then mounted in parallel at least two sets of bulbs. On each series of bulbs is mounted in series a diode. On a series of bulbs is mounted in series a diode in the direct direction. On the other series of bulbs is mounted in series a diode in the opposite direction.
• This arrangement makes it possible to keep all the display variants proposed by an animator with n powered output channels and a neutral phase which previously was connected to n + 1 wires in the light chain and which, with the invention, supplies a light chain having '' a number of wires less than n + 1.
• the invention therefore makes it possible to reduce the number of wires passing through the light garland relative to the number of power supply channels of the animator to which the light garland is connected.
• the light garland allows a series connection with other light garlands.

• the animator (10) supplies the first output (11) with alternating current, then only the positive half-waves will pass the diode (21) to reach the common supply wire (15) and the current will then only pass in the first bridge (101) since it will be blocked in the second bridge (102) by the diode (32) in reverse. If the animator (10) supplies the second output (12) with alternating current, then only the negative half-waves will pass through the diode (22) to reach the common supply wire (15). The current will then only pass in the second bridge (102) since it will be blocked in the first bridge (101) by the diode (31).
• the invention therefore makes it possible to supply only a series of bulbs (50.1) arranged on the first bridge (101) by supplying the first power outlet (11).
• the invention therefore makes it possible to supply only another series of bulbs (50.2) arranged on the second bridge (102) by supplying the second supply outlet (12).

• the average electric power dissipated by the bridges (101, 102) will be less than the average electric power dissipated by the groups (201, 202) since the diodes (31, 32) will only allow substantially half of the current generated by the animator (10).
