The invention relates to an automatic light extinguisher comprising a holder (2) adapted to fix the same (1) in position on a candle, and a lid or a cap (4) which via a swing arm (5) is pivotably attached to the holder (2) and a trigger mechanism (6) arranged to swing the arm with the cap (4) downwards over the flame (7) of the candle (3) so as to extinguish it when the candle (3) has burnt itself down sufficiently. The trigger mechanism (6) operates with two springs, one (8) resiliently biasing a projection (10) into contact with the wall surface of the candle (3), and one (11) resiliently biasing the swing arm (5) and its cap (4), the projection (10), when in its active position, locking the spring arm (5) with its cap (4) in its upwards directed position, remote from a candle flame (7) and, when in its inactive position, not occurring until the candle has burnt down past the projection (10), which is then in a substantially horizontal position, releases the swing arm (5) with its cap (4) which is then by the biased spring instantaneously swung down over the candle flame (7) so as to extinguish it. |
