Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric ornament, and more particularly, to a blinking display device suitable for an accessory article of an automobile which does not require replacement of a battery.

[0002]

2. Description of the Related Art LEDs are used as interior accessories for automobiles.
There are light sources such as (light emitting diodes) that blink, but most of the time, the power source depends on the onboard battery or batteries.

[0003]

Since the LED consumes little power, when the power source is an on-vehicle battery,
Blinking at all times has almost no effect on battery consumption, but it is still unpleasant to feel when stopped, especially when stopped for a long time. Further, for example, when the main switch is turned off to move away from the car, the power is cut off and the accessories do not function.

In this respect, when the battery is used as the power source, it can be easily turned on and off even when the battery is stopped, but it must be replaced with a new one because it is a consumable item.
In the case of a solar cell, it does not need to be replaced, but it has the inconvenience that it cannot be used when the sunlight is cut off.

The present invention has been made in view of the above-mentioned conventional circumstances, and an object thereof is to eliminate the trouble such as charging work.
It is to provide maintenance-free electric ornaments that can be widely used as car accessories and the like.

[0006]

In order to achieve the above object, the present invention provides a power supply unit, an oscillating unit for turning on and off a current supplied from the power supply unit at predetermined time intervals, and an output through the oscillating unit. In the electrical ornament including a light source that blinks at a current, the power source unit is a combination of a solar cell and an electric double layer capacitor charged by the solar cell, and a casing whose top surface is a stand. It is characterized by comprising a body, mounting the solar cell on a predetermined surface of the same housing, and arranging the light source so as to be exposed on the mounting table.

On this table, for example, a transparent bottle as an aromatic container is detachably arranged. In this case, in order to enhance the decoration effect, it is preferable that the optical fiber or the light reflecting piece is housed in the bottle. Further, by forming a concave portion into which the light source is inserted and fitted in the bottom portion of the bottle, the brightness can be further increased.

A secondary battery may be used instead of the electric double layer capacitor. Further, it is preferable that the power supply section is connected to a switch means for switching charging / discharging of the electric double layer capacitor, particularly a switching transistor whose on / off is controlled by an electromotive voltage of the solar cell.

[0009]

Function: During sunshine, electric energy generated by the solar cell is stored in the electric double layer capacitor. When the day breaks, the electric energy is supplied from the electric double layer capacitor to the oscillating unit and the light source, and the light source blinks. This blinking is particularly effective at night.

The electric double layer capacitor has a large capacitance per unit volume, has no limitation in charging and discharging, and has a long life. Therefore, it can be used almost maintenance-free without requiring replacement.

[0011]

FIG. 1 shows a circuit diagram of a first embodiment of an electric ornament according to the present invention. According to this, the electrical ornament includes the power supply unit 10, the oscillating unit 30 connected to the power supply unit 10 via the switch means 20, and the oscillating unit 30.
And a light source 32 whose blinking is controlled by.

The power supply unit 10 has a solar cell 11 and an electric double layer capacitor 12 which is connected to the solar cell 11 in parallel and charged. In this embodiment, charging and discharging of the electric double layer capacitor 12 is performed. A PNP transistor 21 is used as the control switch means 20.

The solar cell 11 includes an electric double layer capacitor 1
A Zener diode 13 for protecting 2 from its overvoltage is connected in parallel, and a reverse current blocking diode 14 is provided in a charging circuit from the solar cell 11 to the electric double layer capacitor 12.

The transistor 21 has its emitter-collector connected to a current supply path from the power supply section 10 to the oscillation section 30, and its base through a suitable base resistor 22 and auxiliary adjusting resistor 15 for common use in the device. Connected to the side.

In this embodiment, the oscillating unit 30 includes an oscillating circuit 31 having two output terminals OUT1 and OUT2, and LEDs (light emitting diodes) 32a and 32b as light sources are connected to the output terminals OUT1 and OUT2, respectively. Has been done.

A resistor 33 for limiting current and an electrolytic capacitor 34 are connected to the input side of the oscillator circuit 31. The capacitor 34 is a capacitor that instantly supplies the light emission energy to the LEDs 32a and 32b, and it is required that the internal resistance be low and the leakage current be small so that a large current can be taken out. On the other hand, the electric double layer capacitor 12 is required to have characteristics such that self-discharge is small even if the internal resistance is high.

In the above structure, when the solar cell 11 is in the electromotive state due to sunlight, the emitter potential and the base potential of the transistor 21 are kept at the same potential, so that the transistor 21 is off and therefore the solar cell is The electric energy generated at 11 is the electric double layer capacitor 1
Charged to 2.

When the electromotive force cannot be obtained from the solar cell due to the break of the day, the emitter potential of the transistor 21 becomes lower than the base potential, so that the transistor 21 turns on. As a result, the energy stored in the electric double layer capacitor 12 is charged in the capacitor 34, and the LEDs 32a and 32b alternately blink through the oscillation circuit 31.

Here, the electromotive force of the solar cell 11 is 2.0
V, 200 mA, the rating of the electric double layer capacitor 12 is 2.4 V2.2 F, the current limiting resistor 33 is 10 kΩ, the base resistor 22 is 1 MΩ, the adjusting resistor 15 is 100 kΩ, the electrolytic capacitor 34 is rated 16 V 100 μF, and the oscillator circuit is used. First, the solar cell 11 is exposed to sunlight for 20 minutes by using a stepping motor driving IC (model number SM5546) manufactured by Nippon Precision Co., Ltd. 31 and alternately turning on the two LEDs 32a and 32b for 40 msec every second. The electric double layer capacitor 12 was charged.
At this time, the charging voltage of the electric double layer capacitor 12 is 2.
It was 2V.

After that, the solar cell 11 was shielded from light. Along with this, the transistor 21 is turned on, and the electric double layer capacitor 12 starts discharging,
The LEDs 32a and 32b start blinking alternately, and this state continues for about 5 hours.

This service life depends on the capacitance of the electric double layer capacitor 12, the light emission time and the light emission interval set by the oscillation circuit 31, and can be adjusted arbitrarily.

As another circuit example, as shown in FIG. 2, a manual changeover switch 21a may be used as the switch means 20 to arbitrarily turn on and off. In some cases, as shown in FIG. 3, the switch means 20 may be omitted and the power supply section 10 and the oscillation section 3 may be omitted.
It is also possible to connect 0 directly and to make it always blink while charging.

Furthermore, although an electric double layer capacitor is used in each of the above embodiments, a secondary battery may be used instead of the electric double layer capacitor in view of the concept of an energy storage element.
