1 (a) and 1 (b), there is shown a lantern T equipped with the production lighting device of the present invention. This lantern T is located at the uppermost part, and is shown in FIG. 1 (b) directly below the roof body 1 composed of two roof portions 1A, 1A which are mountain-shaped in a front view. A large number of light emitting diodes 2 (see FIG. 3A) are arranged, and
An illumination unit 4 located on the upper side of the light-emitting diode 2 covered with a casing 3 made of a transparent or semi-transparent synthetic resin (which may be made of other materials such as glass and Japanese paper) which is substantially rectangular in a plan view, A leg made of a metal having a substantially rectangular shape in plan view (which may be made of any material as long as it has a strength such that it is not easily deformed) and which constitutes a leg to be supported below the lighting unit 4. However, the specific configuration such as size and shape may be any one. Reference numeral 6 shown in the figure is two solar cells provided in the roof body 1, and 6a is a code for each solar cell 6. Further, the above-mentioned production lighting device can be used not only for a lantern, but also for a candle-shaped lamp or other lighting equipment used for production. In FIG. 2, lanterns T are installed at predetermined intervals on both sides of a passage H formed by laying a large number of stones.

The light emitting diode 2 is shown in FIG.
As shown in (b), a large number of light-emitting diodes 2 are arranged in the circumferential direction without gaps over the entire surface of the substrate 7 which is circular and annular (any shape such as an ellipse or a rectangle). With the irradiation surface thereof facing forward and the optical axis extending along the radial direction passing through the center of the substrate 7 to form one light emitting unit 8, the same light amount can be obtained from any angle. Although the light emitting diodes 2 can be illuminated, the light emitting diodes 2 may be spread only over a specific portion so that only a specific direction is illuminated. The substrate 7 is formed of a circular or annular shape from the beginning, or a shape-changeable material that can be rolled into a circular and annular shape after the light emitting diodes 2 are spread over a flat plate shape. May be. A plurality of light-emitting units 8 configured in this way (10 in the figure, but any number of two or more, but the greater the number, the more advantageous for the fluctuation phenomenon described later), As shown in FIG. 1 (b), by arranging them at appropriate intervals in the vertical direction and using the drive control means 20 described later,
It is possible to express (reproduce) light that is similar to the flame of a candle. The number and position of the light emitting diodes 2 are not limited to those shown in the figure.
Although the ten substrates 7 have the same diameter, they may have different diameters. In this case, by arranging ones having a diameter close to the shape of the candle flame up and down, the flame of the candle can be made closer to the flame. 1 (b) and 3 (a),
In FIG. 8B, the light emitting diode 2 is attached to each of the ten substrates 7, but as shown in FIG.
All the light emitting diodes 2 may be attached to one substrate 7. Further, the mounting positions of the light emitting diodes 2 on the substrate 7 may be arranged in the same vertical and horizontal positions as shown in FIG. 8, or may be staggered or irregularly arranged.

A drive circuit for driving the light emitting diode 2 will be described with reference to FIG. The solar cell 6 is composed of a solar panel 6A that converts the light energy of sunlight into an electric current, and a storage battery 6B that can be stored as an electric charge by the electric current from the solar panel 6A.
Instead of the solar cell 6, a power source other than a commercial AC power source such as wind power generation may be used. Then, a control device 9 for driving (light emitting) the light emitting part 8 by the electric charge (electric power) accumulated in the storage battery 6B, and a drive start signal, a drive stop signal and a drive control signal (light emitting part) for the control device 9. Infrared remote controller (remote operation means) 10 for inputting a signal for controlling the light emission pattern 8)
A reception sensor 11 for receiving infrared rays transmitted from the remote controller 10 and inputting a signal to the control device, a voltage detection unit 12 for detecting a voltage value of the solar panel 6A, and a current of the solar panel 6A. When the voltage value from the current detection unit 13 that detects the value and the voltage detection unit 12 falls below a predetermined voltage value (that is, at night when the storage battery 6B cannot be charged by the sunlight, or the solar panel 6A has failed). At the time), an AC-DC power source 14 for converting the AC voltage from the commercial AC power source into a direct current to charge the storage battery 6B, and the light emitting unit 8 in the storage battery 6B.
A switch 15 for shutting off the voltage supply from the commercial AC power source to the AC-DC power source 14 only when driving the battery, and a circuit for shutting off the circuit for blocking the load charging when the storage battery 6B is fully charged. A circuit breaker switch 15, a control switch 16 and a resistor 17 for controlling the voltage from the solar panel 6A, and a backflow prevention diode 1
8 and a backup battery 19 for a timer (clock) provided in the control device 9. Therefore, using the solar panel 6A to utilize the sunlight, the storage battery 6
When B cannot be charged, the storage battery 6
Since B can be fully charged, its storage battery 6B
Thus, the light emitting section 8 can be driven for a long time. And
By setting the driving time of the light emitting unit 8 with a timer, it is possible to prevent the driving of the light emitting unit 8 for an unnecessary time due to forgetting to turn off. By operating the lantern installed at a particularly high position by the remote controller 10 as described above, there is an advantage that the lantern can be easily operated. In FIG. 4, the solar panel 6A
Although the case where the storage battery 6B is charged by the commercial AC power supply is shown, a large capacity solar panel that can be charged only by the solar panel 6A may be used. In addition, the light emitting unit 8 is connected to the storage battery 6B.
In addition to being configured to be driven only by a solar panel, it is possible to drive the light emitting unit 8 for a long time while achieving energy saving by using it together with a commercial AC power source. It is also possible to omit 6A and drive the light emitting unit 8 only with a commercial AC power source,
The drive circuit for the light emitting unit 8 can be freely changed. The remote controllers 10 may be provided in the same number as the lanterns, and each lantern may be remotely operated by a dedicated remote controller 10, or a single remote controller 10 may be provided.
It is also possible to remotely control all lanterns.

As shown in FIG. 5 (b), the control device 9 has three light emitting diode groups X, which are vertically divided into three groups, as a changing means for changing the amount of electricity supplied to the light emitting diodes 2. Drive control means 2 for driving Y and Z by sine waves which are different drive signals, that is, sine waves having the same radius of curvature and different peak values of current.
0 (see FIG. 4). Therefore, the light intensity (luminance) in each part is changed with time by making each light emitting diode group X, Y, Z emit light with different sine waves so that the light intensity (luminance) is partially different. By making it different with the passage of time, it is possible to emit a light similar to the fluctuation of a candle flame. Incidentally, FIG.
In (a), the maximum peak value of the light emitting diode group X indicated by the solid line is approximately 3 A (ampere), and the maximum peak value of the light emitting diode group Y indicated by the alternate long and short dash line is approximately 2.3 A (ampere). The maximum peak value of the light emitting diode group Z shown is approximately 1.3 A (ampere), but the present invention is not limited to this value. Although one cycle S is set to 8 seconds in any sine wave, any value may be set as long as it is 14 seconds or less. If the period is set to exceed 14 seconds, the change in brightness is small and it becomes difficult to express the fluctuation of the candle flame. In addition, although it is divided into three groups here, it may be divided into two or four or more groups, but the larger the number of divisions, the closer to the fluctuation of the candle the faithful representation. You can Further, the groups may be divided not only in the vertical direction but also in the horizontal direction, or may be divided similarly to a candle flame. In place of the sine wave shown in FIG.
By driving and controlling the light emitting section 8 provided in each lantern T using the sine waves X, Y, and Z shown in FIG. 1, it is possible to more realistically produce a lighting state that is rich in variation, that is, a fluctuation phenomenon. May be.

In FIGS. 5 (a) and 5 (b), the light emitting section 8 provided in each lantern T is drive-controlled so as to be able to express the fluctuation of the flame of the candle, but FIGS. As shown in, the light emitting units 8 are driven by sine waves, which are different drive signals that change with the passage of time, in different lighting states of the light emitting units 8 for each lantern. In other words, the light emitting unit 8 of the specific lantern M selected from a large number of lanterns T is generated by a sine wave with one cycle S1 of 8 seconds (any value may be set as long as it is 14 seconds or less). Driven,
Also, the light emitting part 8 of the lantern L selected from the remaining lanterns
Is driven by a sine wave having a period S2 of 6 seconds (any value may be set as long as it is 14 seconds or less), and the light emitting unit 8 of the remaining lantern N has a period S3 of 14 seconds. The control device 9 is provided with the first control means 21 and the second control means 22 so as to be driven by a sine wave of a second (any value may be set as long as it is 14 seconds or less). There is. Therefore, the light emitting portion 8 of the lantern M is controlled by the first control means 21 as shown in FIG.
When all lanterns are viewed by being driven by the one sine wave shown in FIG. 6 and the light emitting section 8 of the lanterns M and N being driven by the two sine waves shown in FIG. There are lanterns with different luminosity, and the luminosity of these lanterns changes with the passage of time, so that it is possible to perform an effect by changing the light. By making the cycles of the three sine waves different from each other, it is possible to produce a variety of light effects, but it is also possible to change the amplitude in the same cycle or shift the phase. Although the lantern T is divided into three groups M, L, and N, it can be divided into two or four or more groups.
It should be noted that the larger the number of groups, the more advantageous the light production. Although the peak value of the current is 3 A (ampere) in FIG. 6, it may be set to any value. Although FIG. 5A and FIG. 6 show the one in which the luminance is changed, the effect of light may be enhanced by changing the color. Also, as shown in FIG.
By using a sine wave as the drive signal, the brightness of the light emitting portion 8 is gradually changed, and the fluctuation of the candle flame can be expressed more realistically, but the triangular wave or the like also expresses the fluctuation of the candle flame. be able to. Alternatively, a candle flame that is actually lit may be received by a light receiving element such as a photodiode, and the lighting state (light emitting pattern) of the light emitting unit 8 may be controlled based on the received light amount.
