Abstract

PROBLEM TO BE SOLVED: To stabilize a lighting state or a flashing state, and to eliminate consumption of a contact point by lighting a light emitter by electrically continuing an element by impressing voltage of an operating circuit on a switching element when a vibrating switch contact point is closed. SOLUTION: A semiconductor switching element by a transistor 9 is provided in a light emitting circuit for connecting a battery 1 to an LED 4 of a light emitter, and the transistor 9 is operated by an operating circuit composed of a vibrating switch contact point 7, a capacitor 10 and a resistance 11. That is, when the vibrating switch contact point 7 is electrically continued, voltage of the battery 1 passing through the capacitor 10 is impressed on a base of the transistor 9 via the resistance 11, and the transistor 9 is electrically continued to light the LED 4. Thus, even if the vibrating switch contact point 7 frequently contacts and separates by vibration, since voltage stored in the capacitor 10 is impressed on the base of the transistor 9, operating voltage does not become unstable, so that a stable lighting state can be realized.

It is a front view of the apparatus of FIG.

In FIG. 3, reference numeral 1 denotes a battery, which here includes either a primary battery or a secondary battery, or a combination of these and a solar battery. Reference numeral 2 denotes an optical sensor switch inserted into the circuit of the battery 1, which is of a type in which a contact is opened when external light is input and the contact is closed when no external light is input. In some embodiments of the present invention, the switch 2 is not provided.

Reference numeral 3 denotes a blinking circuit inserted into the circuit of the battery 1, and 4 denotes an LED which is caused to blink by the blinking circuit 3.
In the present invention, one or more LEDs may be juxtaposed. An electric light (electroluminescence lamp) or a small light bulb may be used instead of or in combination with the LED 4, and a capacitor may be inserted in the power supply circuit depending on the rating of the luminous body used. .

Reference numeral 5 denotes an open / close switch of this circuit inserted into the circuit of the battery 1 and is turned on / off by a timer 6. That is, while the timer 6 measures the time set therein, the timer 6 is kept closed, and when the time measured by the timer 6 reaches the set value, the timer 6 is reset to the initial state and the switch 5 is opened. Is done.

Start of the timer 6 (operation start)
Is performed by the action of a vibration switch contact 7 and a timer switch circuit 8, which will be described later. First, the vibration switch contact 7 includes a spring 7a made of an electric conductor connected to the circuit of the battery 1 and a metal weight 7b provided at the upper end of the spring 7a.
And a fixed contact 7c that is contacted by vibrating or oscillating the weight 7b.
7c is connected to one input terminal on the input side of the OR gate 8a in the timer switch circuit 8.

An output of the timer 6 is connected to the other input of the OR gate 8a, and an output of the OR gate 8a is connected to a start switch 8b of the timer 6.
Is switched to the ON side.

On the other hand, the terminal for switching the start switch 8b to the off side is connected to the output side of an AND gate 8c in which two terminals on the input side are connected to the circuit of the battery 1 and the timer 6, respectively. The start-up switch 8b is turned off by the output of the gate 8c formed by the activation of the battery 6 and the closing of the battery circuit.

The battery 1 to the timer switch circuit 8
With the configuration described above, an example of the decorative lamp device of the present invention is configured. As illustrated in FIGS. 1 and 2, the decorative lamp device is mounted on, for example, a center cap Cp of an automobile wheel Wh.
The LED 4 and the optical sensor switch 2 are exposed in the housing Ca or the case Ca integral with or separate from the cap Cp so as to face the outside of the case Ca. Here, the LED 4 and the optical sensor 2a are exposed to the outside through a hole Lh formed in the center cap Cp. Reference numeral 9 denotes a fixing means such as a double-sided tape or an adhesive for fixing the case Ca to the back surface of the center cap Cp.

The center cap constructed as described above
The decorative lamp device of the present invention provided on the back surface of Cp operates as follows. First, since the light sensor switch 2 is off (open) in response to external light in the daytime, the LED 4 does not light up regardless of the state of the timer switch circuit 8.

On the other hand, when there is no external light, that is, at night, the optical sensor switch 2 is closed.
D4 is controlled by the open / closed state of the open / close switch 5 of the power supply circuit. That is, when the switch 5 is closed, the LED 4
Flashes by the action of the flashing circuit 3 and remains off when the switch 5 is open.

The open / close switch 5 is turned on and off according to the operation state of a timer 6 and a switch circuit 8 for controlling the start of the timer 6.
That is, at night, when the car runs and the wheels rotate,
First, the optical sensor switch 2 is open, and the vibration switch contact 7 intermittently opens and closes due to the swing of the weight 7b. When the switch is initially closed, one input terminal of the OR gate 8a is connected to the input terminal. While there is an input due to the closing of the contact 7, there is no input at the other input of the gate 8a, which is connected to the timer 6, since the timer 6 has not yet been activated, thereby providing this OR gate 8a with an input. Generates an output signal, which switches the switch 8b to the ON side and holds it.

When the switch 8b is turned on, the timer 6 starts. When the timer 6 starts operating, a signal to that effect is input to the OR gate 8a.
, But the switch 8b remains on.

On the other hand, by the operation of the timer 6, the open / close switch 5 of the power supply circuit is switched to the closed side, and the battery 1 is turned on.
Since the blinking circuit 3 and the circuit for the LED 4 are closed,
ED4 starts blinking. The contact of this open / close switch 5 is kept on the closed side while the timer 6 is performing the timing operation. At this time, the AND gate 8c having the input connected to the circuit of the timer 6 and the battery 1 has two inputs at the same time.
8b, the switch 8b is turned off. While the timer 6 is operating and the circuit of the battery 1 blinks the LED 4, the output of the AND gate 8c keeps the switch 8b off.

When the time of the timer 6 reaches the set value, the switch 5 is turned off and the LED 4 stops blinking. However, as long as the wheel is rotating, that is, the automobile is running, the condition of the OR gate 8a is as follows. Immediately after the contact of the vibration switch contact 7 and the non-operation of the timer 6, the condition for the switch 8b to be switched to the ON side is reached.
Is activated, and the above-described blinking state of the LED 4 is created.

In the present invention, the blinking LED 4
Is turned off when the time counted by the timer 6 reaches the set value, so that the blinking continues if the timer 6 is still counting even if the vehicle stops running. Therefore, in the present invention, it is desirable that the set time of the timer 6 is set to a short time, for example, about 5 minutes to 15 minutes, and the length is set to be short and long enough to allow the time for stopping the running and keeping the LED 4 blinking.

In the above example, the decorative lamp device of the present invention is provided with the optical sensor switch 2, and this device is mounted on the vehicle wheel Wh.
Although the decorative lamp device of the present invention does not have the optical sensor switch 2, that is, the decorative lamp device of the present invention may be of a type having a performance that can be operated even in the daytime. It goes without saying that a form other than the example may be used. For example, although not shown, the device of the present invention may be incorporated in a valve cap of a tire, or may be designed in a form that matches the installation location on the front and rear bumpers, the body side, the hood and the trunk lid, etc. If the case Ca of the device of the present invention is attached, the design effect can be further improved.

Next, another example of the decorative lamp device of the present invention will be described with reference to FIG. In FIG. 4, the same reference numerals as those in FIG. 3 denote the same members. In the circuit illustrated in FIG. 3, a light emitting circuit that connects the battery 1 and the LED 4 provided as an example of a light emitting element includes a semiconductor switching element including a transistor 9 here, and the vibration switch includes the transistor 9 inserted into the light emitting circuit. Contact 7, capacitor
Conduction operation is performed by an operation circuit including a resistor 10 and a resistor 11.

That is, in the circuit shown in FIG. 4, when the vibration switch contact 7 is turned on, the voltage of the battery 1 via the capacitor 10 is applied to the base of the transistor 9 via the resistor 11, so that the transistor 9 is turned on. LED 4 is turned on.

In the circuit shown in FIG. 4, even if the switch contact 7 frequently comes and goes due to vibration,
As for the voltage of the battery 1, the voltage stored in the capacitor 10 is applied to the base of the transistor 9, so that the operating voltage of the transistor 9 does not become unstable. Therefore, a stable lighting state is realized by a simple circuit configuration. it can. Further, the circuit of FIG. 4 has fewer circuit components than the circuit configuration of FIG. 3, so it is advantageous in terms of cost, and also has the advantage of reducing the number of components and causing fewer failures. Since the vibration switch contact 7 is opened when there is no vibration or the like, the operation circuit including the contact 7 does not operate, the conduction of the transistor 9 of the light emitting circuit is cut off, and the LED 4 is extinguished.

FIGS. 5 and 6 show that the decorative lamp device of the present invention described with reference to FIG. 3 or FIG. 4 is assembled on the back side of the center cap Cp, while the reflecting plate 9 is arranged behind the LED 4 and the front side of the LED 4. This is an example in which the side is formed so as to be covered with a transparent body 10 such as a lens. In this case, the center cap Cp itself is formed so as to form the main body of the device of the present invention.

In the decorative lamp device of the present invention illustrated in FIGS. 5 and 6, a short cylindrical housing 11 is formed on the back surface of the center cap Cp, and the center of the housing 11 is made detachable by a screw 12. A battery case 14 having a lid 13 is formed, and a vibration switch 7 and a capacitor which form a circuit of the device of the present invention are formed in spaces on both sides of the battery case 14.
A circuit board on which a 15, a timer 6, a switch circuit 8 and the like are arranged is housed, and these are sealed in a watertight manner.
