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.
