In this case, the included angle reflecting screen 5 is jointly formed by three milky films 9 distributed on the same center line at equal angles, the included angle between two adjacent milky films is 120 degrees, and a circular hole 10 for sleeving on the metal wire is formed at the lower end of the center line; the quantity of the color flame projectors 6 is the same as that of the milky films, the three color flame projectors are distributed on the same circumference at equal angles with the included angle reflecting screen as a center, and each color flame projector is located in a relationship of one-to-one correspondence with the included angle between the two adjacent milky films; each color flame projector 6 is jointly composed of a support 11, color tubes 12 arranged on the support, a color flame film 13 and a convex lens 14; the color tubes 12 are jointly composed of red, white and yellow LED tubes; the driver is composed of a circuit board 15 and an electromagnetic coil 16 fixed on the circuit board; the overall power supply is formed by connecting a power supply 17 and a power switch 18 in series; the power supply 17 and the power switch 18 are respectively electrically connected with the circuit board to form a closed circuit, and the circuit board is electrically connected with the color tubes. When the power switch is turned on, the whole candle starts working, the color LED tubes start emitting light, and a color flame shadow is formed within the included angle between the two adjacent milky films. Because the current in circuit board can produce intermittent pulse oscillation, the coil produces magnetism; the magnetism instantaneously attracts or releases the soft iron sheet, and the spring is disturbed by intermittent tension to drive the included angle display screen to move up and down, so that a vivid dynamic flame feeling is formed.
