The present invention relates to an electric decoration device that can be attached and make these decorative miniature light bulbs blink by a battery.

[Conventional technology]

For example, a Christmas tree is generally a tree trunk base of a natural tree or an artificial tree, which is installed indoors or outdoors using a stand having a flowerpot-shaped base and legs, and its branches have , A large number of flashing light bulbs are installed together with other ornaments.

Such a group of illuminated lights automatically blinks with a bimetal, and since it is assumed that they will be used for a long time, the AC power supply is generally the mainstream power supply.
As shown in No. 17681, it is also practiced to convert an AC power supply into a DC power for use.

[Problems to be solved by the device]

However, the use of the AC power supply is restricted by the length of the electric wire and the installation place is limited, and it is not possible to freely place it in any place, and wiring from the outlet to the place where the Christmas tree is placed is It is extremely troublesome, and there is a risk that a person may catch the cord and collapse the tree, and there is also a risk that the leakage or the device may be heated due to the relatively high AC voltage and current.

In particular, not only a long cord is required outdoors, but also a key part of this wiring portion needs to be waterproof.

In consideration of the current situation, this invention uses a battery that is a DC power source as the power source, enables blinking with sufficient brightness and connectivity, and has a compact form that provides sufficient waterproof performance without limiting the installation location.

In particular, in this invention, the electric decoration holding member that engages and holds the electric decoration lamp group is held upright and non-rotatable with respect to the base, so that it may be accidentally fallen or the electric power may be lost during use. There is no twist of the decoration lamp group.

Also, since a blinking circuit and a battery for tipping over the illuminated lamp group are incorporated in the base, the appearance is extremely good and at the same time, these relatively heavy items play the role of weight. Since the illumination holding member can be stably held on the base and the illumination lamp is operated by the battery, the position where the illumination device is placed can be freely selected.

Further, in the lighting lamp group, a large number of decorative miniature light bulbs are connected in parallel and a transistor is used as a switch of the lighting lamp group, and the output signal of the decoder for switching the transistor is used as the output signal of the comparator. Since it was made dependent, the illumination lamp group automatically starts blinking just by operating the switch provided on the base, and the battery consumption is very low, so the illumination device can be used for a long time,
The group of illuminated lamps has a great effect in practical use, such as always having a bright brightness.
