[0014] The base 1 is provided with a through inserted hole H1 and a circuit unit 5, where the circuit unit 5 includes a plurality of light emitting elements 52 respectively in electric connection with a circuit board 51 locked to the bottom of the base 1 with screws S, each of the light emitting elements 52 irradiates the inserted hole H1, and the on-off sequence of each of the light emitting element 52 is controlled by the circuit board 51. In the embodiment, the light emitting element 52 preferably is an LED.

[0015] The light guiding unit 2 includes at least two light guiding plates 21 stacked on the top of base 1, the bottom of each of which is provided with at least one light entrance 22, and the light entrances 22 is inserted in the inserted hole H1 and face the corresponding light emitting elements 52; the surface of each of the light guiding plates 21 is configured with a decorative pattern 24, which may be a totem, animal, plant, character or text pattern related to a festival; and the decorative patterns 24 of the two light guiding plates 21 may be a continuous action or staggered arrangement. In addition, the light emitting elements 52 is preferably in contact with the corresponding light entrances 22 of the light guiding plates 21, allowing light to be directly injected into each of the light guiding plates 21. Furthermore, both sides of the light entrance 22 of each of the light guiding plates 21 are respectively provided with a shoulder 23 adapted to lap on the top of the base 1.

[0016] One end of the inserting rod 3 is fixed to the bottom of the base 1, and another end thereof is provided with a tapered inserting portion 31 in order to be inserted into the soil, and the present invention does not limit the way of fixation of the inserting rod 3 to the base 1, which may be screwing, adhesion or embedding.
