  • Patent number: 4551794
    Abstract: An imitation candle includes an elongated outer candle-casing (43), having located at one end thereof an electric light bulb (1) carried on one end of a pendulum. The other end of the pendulum carries a counterweight (18) comprising, at least in part, a permanent magnet (21). The pendulum is mounted on two wire-like elements (15) extending in a common plane from a common connector (11) on the pendulum. The ends of the wire-like elements remote from one another are anchored in a holder (23) located around the pendulum. The poles of the permanent magnet (21) lie on a line extending at right angles to the longitudinal axis of the pendulum. The two wire-like elements (15) extending from the common connector (11) in diametrically opposite directions preferably form conductors (3,4) leading to the electric light bulb.

  • Patent number: 4550363
    Abstract: To simulate a candle flame an electric-light bulb (15) is fitted with a light-permeable and light-scattering lamp casing (1). Arranged on the inner surface (5) of the lamp casing are spacing elements (6,7,8) which hold the outer surface (14) of the light bulb (15) spaced from the inner surface (5) of the lamp casing (1). The lamp casing (1) is open at both ends, and cooling air is conducted along the inner surface of the lamp casing by convection.
