PROBLEM TO BE SOLVED: To electrically control fed bodies such as an electric candle, etc., so that they have natural lambency. SOLUTION: A light-transmissive protection case is mounted to an upper part of a candle body of this electric candle, and first-third light-emitting bodies 5a-5c are provided in the protection case. First and second random pulse generating parts 20, 30 integrating shift registers 21, 31 with exclusive-OR circuits 22, 32 are provided to a random signal generator 10 built in the candle body 2. Here, first-third transistors Tr1-Tr3 provided on the ground side of respective current-carrying circuits of the parallel first-third light-emitting bodies 5a-5c are turned on and off by output signals of the first random pulse generating part 20. While, fourth-sixth transistors Tr4-Tr6 respectively in parallel with them are turned on and off by output signals of the second random pulse generating part 30. |
