[0021]

In the decorative light bulb device of the present invention, the decorative light bulb device side has the self-identification function of selecting only a necessary electric signal from the electric signals commonly transmitted to a large number of decorative light bulb devices. Therefore, even if many decorative light bulb devices are commonly wired to the covered electric wire, each of the decorative light bulb devices can be operated independently. In other words, unlike the conventional case, it is not necessary for each light bulb to be wired one-to-one with the control device side by independent wiring. The control device transmits an electric signal for control through a common covered electric wire, and the decorative light bulb device itself selects a related signal from a large number of common electric signals.

At this time, the control device that generates a command signal identifies 16 decorative light bulb devices that can uniquely identify a unique identification signal. It is possible to freely control and express all the combinations of lighting states at the same time and the order of lighting with the passage of time without changing wiring.

[0024] For example, 2 for supplying electric power for lighting a light bulb
A large number of decorative light bulb devices can be connected in series or in parallel by constructing the pair of power supply lines and a signal line for electric signals (the ground line is also used as the power supply line) with a flat cable having three core wires. When the decorative light bulb devices commonly receive and decode the 6-bit command signal through the signal line, and when the 4-bit identification signal included in the command signal matches with its own, the remaining 2-bit control signal According to the contents of 1., for example, the lighting circuit from one power supply line to the other power supply line through the light bulb is closed. In addition to this, the 2-bit control signal is used for selecting one of the three light bulbs of red, blue and green, and for the four light bulbs of one light bulb.
It can be used for the purpose of selecting one from the illuminance levels.

While using only the identification signal as the command signal, the decorative light bulb device side may be provided with a function of continuing lighting for a certain period of time. Lighting is continued for this decorative light bulb device as long as the next matching identification signal is repeatedly emitted from the control device within this fixed time.

The electrical signals are transmitted and received as follows: 1. The control device side converts parallel command signals into serial signals and transmits a signal consisting of a digital pulse train through a pair of signal lines, while the decorative light bulb device side Then, it is possible to adopt a format in which a received signal is compared with a clock pulse uniquely generated on the decorative light bulb device side and a parallel command signal is reproduced in a shift register. In addition, 2. The control device FM-modulates the command signal to generate an FM alternating current, while the decorative light bulb device side reverse-modulates the FM alternating current to extract the command signal. The command signal may be AM-modulated and superimposed on the AC voltage, while the decorative light bulb device may take out the command signal through an appropriate bandpass filter. Other commonly recognized formats are also available. Appropriate ones are selected for the receiving circuit and the extracting circuit according to the form of transmission and reception of such electric signals.

When digital signal processing is selected in the extraction circuit, the setting circuit displays a digital switch having the number of digits of the number of bits of the binary identification signal and the binary number converted into a decimal number and displayed. Digital thumbwheel switch is available. On the other hand, when analog signal processing is selected in the extraction circuit, a voltage comparison circuit (comparator) in which a voltage setting circuit in which a constant voltage is divided by a resistor and an amplifier are combined can be used as the setting circuit.

The power supply circuit can be composed of, for example, a relay contact, a transistor switching circuit, a thyristor circuit, etc. if it is a simple ON-OFF control. In the case of control including increase / decrease of light quantity, pulse width control using a transistor switching circuit or a transistor amplifier circuit whose base current is analog-controlled can be used.

According to the decorative light bulb device of the second aspect, only two covered electric wires are connected in series or in parallel. An electrical signal for controlling the decorative light bulb device is superimposed on the DC or AC power supply through the coated wire.

When the supplied power is DC, the control device for generating the command signal is controlled by, for example, a DC voltage which is matched with 1-0 of the parallel digital signals transmitted at time intervals controlled by the clock pulse. Can be turned on to 0FF and a serial signal consisting of a digital pulse train can be transmitted. At this time, the control device serially converts the parallel command signal including one identification signal. On the other hand, on the decorative light bulb device side, the electric signal is separated from the supplied power to be received, the command signal including one identification signal is extracted, and the clock pulse of the same frequency uniquely generated on the decorative light bulb device side is extracted. Used to restore the parallel original signal.

The supply power containing the electrical signal is used in a power supply circuit, preferably in the rectified and smoothed state, for the power supply for lighting the bulb.

In the power supply circuit, it is possible to select the power supply to the electric bulb of the type in which the rectified and smoothed DC output is converted into the pulse train of the constant frequency having the different pulse width (duty cycle) by the transistor switching circuit. For example, 1K generated independently on the decorative light bulb device side
Using a clock pulse of Hz, the width (duty cycle) of one DC pulse of 10 Hz is changed in 100 steps. The width of this DC pulse increases or decreases the actual power supplied to the light bulb (average value over the lighting period), and the apparent illuminance of the light bulb changes.

In the decorative light bulb device of claim 3, a function of controlling the pulse width is added to the power supply to the light bulb in the decorative light bulb device, and this function is for improving the illuminance of the light bulb in the decorative light bulb device far from the power supply device. Used exclusively for the purpose. When a large number of light bulbs are connected in parallel to a pair of power supply lines connected to a power supply device and are turned on at the same time, a voltage drop in the power supply lines reduces the illuminance of the light bulb on the terminal side of the power supply lines. The farther from the power supply device or the more light bulbs are turned on at the power source side than the light bulbs, the lower the power supplied to the light bulbs. Therefore, the decorative bulb device side is made to recognize the order of connection of the decorative light bulb devices counted from the power supply device, and the pulse width is increased as the order of connection is larger, and the supply power is reduced due to the voltage drop of the power supply line. To offset.

The identification signal to be set in the setting circuit is supplied from the power supply side, for example, 0001, 00 in the case of a 4-bit binary number.
It can be set in order of 10 and 0011. At this time, the waveform control circuit itself determines the pulse width according to the magnitude of the identification signal of the setting circuit to improve the illuminance of the light bulb in the decorative light bulb device having a large identification signal.

Not protect the electrical structure from the external corrosive atmosphere and moisture such as rainwater.

A slightly large bulb socket can be diverted to the exterior member. For example, inside a pair of cylindrical plastic cases that mechanically hold a light bulb and are screwed together,
A small printed circuit board provided with a metal claw for electrically holding the light bulb and a screwed portion of the power supply line is housed, and an integrated circuit containing an electric circuit is soldered onto the printed circuit board.

In the decorative light bulb device of the fifth aspect, the exterior member is formed in a one-piece two-fold shape. The two-fold shape is formed, for example, by integrally molding the left and right jaws that sandwich the two covered electric wires (feeding wires) and the bent portion that connects the pair of jaws with each other, preferably the two-folded shape. The inside of the shape is formed with a groove that matches the two covered wires, and the left and right jaws are equipped with a locking mechanism that integrates the two on the opposite side of the bent part, and the two covered wires are stored in the groove. Then, the repulsion when sandwiched is held down by the locking mechanism.

The pair of teeth provided in the two-fold shape penetrates the coating of the covered electric wire by the pinching operation and contacts the core wire, and the necessary wiring between the decorative light bulb device and the power supply line is completed only by this pinching operation. Let

In the decorative light bulb device according to the present invention, the operator directly acts on the identification signal setting portion of the setting circuit exposed to the outside of the package of the integrated circuit in a state where the half-folded outer member is opened. To set or change the identification signal.

In the lighting device for a decorative light bulb according to claim 7, the power supply line for lighting the light bulb also serves as a pair of covered electric wires for communicating an electric signal. At least one of the plurality of decorative light bulb devices arranged on the pair of power supply lines has a self-identification function and a function of separating an electric signal from the power supplied through the power supply line.

In the decorative light bulb lighting device of the eighth aspect, each of the plurality of decorative light bulb devices has a self-identification function, and the lighting condition of the light bulb is determined for each decorative light bulb device in a form in response to a call from the control device. It can be changed individually.
The decorative light bulb devices are each connected in a common manner to a covered electric wire for receiving an electric signal from the control device. Here, in the case where the power supply line for lighting the electric bulb also serves as the covered electric wire for the electric signal, it is necessary to give the receiving circuit a function of separating the electric signal from the electric power supplied through the power supply line.
