In the figure, reference numeral 6 denotes two solar cells provided on the roof 1, and reference numeral 6a denotes a cord for each solar cell 6. In addition, the lighting device for effects can be used not only for lanterns, but also for candle-shaped lamps and other lighting fixtures used for effects. FIG. 2 shows an arrangement in which 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 a state where there are no gaps in the circumferential direction over the entire surface of the substrate 7 which is circular and annular (which may be elliptical or square). By laying the light emitting surface 8 in a state where the irradiation surface thereof faces forward and the optical axis extends along the radial direction passing through the center of the substrate 7 to form one light emitting unit 8, the light amount is the same from any angle. Although the light can be illuminated, the light emitting diode 2 may be laid only at a specific location so as to illuminate only a specific direction. The substrate 7 is made of a material that can be formed into a circular shape from the beginning, or a material whose shape can be changed so that the light emitting diode 2 can be laid out on a flat shape and then rounded to form a circular shape. You may. A plurality of light emitting sections 8 configured in this manner (10 in the figure, but any number of 2 or more may be used, but a larger number is more advantageous for a fluctuation phenomenon described later). As shown in FIG. 1 (b), by arranging them at appropriate intervals in the vertical direction and using a drive control unit 20 described later,
It is possible to express (reproduce) light similar to a candle flame. The number and positions of the light emitting diodes 2 are not limited to those shown in the figure.
Further, the ten substrates 7 have the same diameter, but may have different diameters. In this case, by arranging up and down ones having a diameter close to the shape of the candle flame, the flame can be made even closer to the candle flame. 1 (b) and 3 (a),
FIG. 8B shows the case where the light emitting diodes 2 are attached to the ten substrates 7 respectively, but as shown in FIG.
All the light emitting diodes 2 may be attached to the individual substrates 7. The mounting positions of the light emitting diodes 2 on the substrate 7 may be staggered or irregularly arranged as shown in FIG.

A driving 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 light energy of sunlight into a current, and a storage battery 6B that can be stored as electric charge by the current from the solar panel 6A.
Instead of the solar cell 6, a power supply other than a commercial AC power supply such as wind power generation may be used. Then, a control device 9 for driving (light emitting) the light emitting unit 8 by the electric charge (power) stored in the storage battery 6B, and a driving start signal, a drive stop signal, and a drive control signal (light emitting unit) Infrared remote controller (remote control means) 10 for inputting a signal for controlling the light emission pattern 8

When the voltage value from the current detection unit 13 that detects the value and the voltage value from the voltage detection unit 12 falls below a predetermined voltage value (that is, during the night when the storage battery 6B cannot be charged by sunlight, or when the solar panel 6A fails. At the time), an AC-DC power supply 14 for converting an AC voltage from a commercial AC power supply to a direct current to charge the storage battery 6B, and a light emitting unit 8 using the storage battery 6B.
And a switch 15 for cutting off the voltage supply from the commercial AC power supply to the AC-DC power supply 14 only when the battery 6 is driven, and a circuit for cutting off the circuit for preventing the charge from being charged when the storage battery 6B is fully charged. A circuit cutoff switch 15, a control switch 16 for controlling the voltage from the solar panel 6A and a resistor 17, and a backflow prevention diode 1
8, a backup battery 19 for a timer (clock) provided in the control device 9. Therefore, the solar battery 6A uses the sunlight to store the storage battery 6.
B cannot be charged using a commercial AC power supply.
B can be completely charged, so that the storage battery 6B
, The light emitting section 8 can be driven for a long time. And
By setting the driving time of the light emitting unit 8 by a timer, it is possible to prevent the driving of the light emitting unit 8 for an unnecessary time due to forgetting to cut. In particular, there is an advantage that the operation of the lantern can be easily performed by remotely controlling the lantern installed at a high position by the remote controller 10 as described above. In FIG. 4, the solar panel 6A
Although the case where the storage battery 6B is charged with the commercial AC power supply is shown, a large-capacity solar panel that can be charged only with the solar panel 6A may be used. Further, the light emitting unit 8 is connected to the storage battery 6B.
In addition to the configuration in which the light-emitting unit 8 is driven only by using a commercial AC power supply, there is an advantage that the light-emitting unit 8 can be driven for a long time while energy saving can be achieved. It is also possible to omit the 6A and drive the light emitting unit 8 only with the commercial AC power supply,
The drive circuit for the light emitting unit 8 can be freely changed. The remote controller 10 may be provided in the same number as the lanterns, and may be remotely controlled by a dedicated remote controller 10 for each lantern, or a single remote controller 10 may be used.
May be used to remotely control all lanterns.

The control device 9 includes three light emitting diode groups X and X divided vertically into three groups as shown in FIG. 5B as changing means for changing the amount of current supplied to the light emitting diodes 2. Drive control means 2 for driving Y and Z by sine waves as different drive signals, that is, sine waves having the same radius of curvature and different current peak values.
0 (see FIG. 4). Therefore, the light intensity (luminance) at each portion is changed over time in a state where the light intensity (luminance) is made partially different by causing each of the light emitting diode groups X, Y, and Z to emit different sine waves. By making it different over time, it is possible to emit light similar to the fluctuation of the flame of a candle. FIG.
In (a), the maximum peak value of the light emitting diode group X indicated by a solid line is approximately 3 A (ampere), the maximum peak value of the light emitting diode group Y indicated by a dashed line is approximately 2.3 A (ampere), and Although the maximum peak value of the illustrated light emitting diode group Z is set to approximately 1.3 A (ampere), the present invention is not limited to this value. Further, one cycle S is set to 8 seconds for any sine wave, but any value may be set as long as it is 14 seconds or less. If the period is set to be longer than 14 seconds, the change in luminance is so small that it is difficult to express the fluctuation of the flame of the candle. In addition, here, it is divided into three groups, but it may be divided into two or four or more groups. However, the more the number of divisions, the more faithfully the state closer to the fluctuation of the candle Can be. Further, the group may be divided not only in the vertical direction but also in the horizontal direction, or may be divided in the same manner as a candle flame. Instead of the sine wave shown in FIG.
By controlling the driving of the light-emitting unit 8 provided in each lantern T using the sine waves X, Y, and Z shown in (1), a more varied lighting state, that is, a fluctuation phenomenon can be more realistically produced. You may.

In FIGS. 5 (a) and 5 (b), the light emitting section 8 provided in each lantern T is drive-controlled so that the fluctuation of the flame of the candle can be expressed. FIGS. 2, 6 and 7 As shown in the figure, the light emitting units 8 are driven by sine waves which are different driving signals which change with time in a state where the lighting states of the light emitting units 8 for each lantern are different. That is, the light-emitting unit 8 of the specific lantern M selected from the many lanterns T is a sine wave in which one cycle S1 is 8 seconds (any value may be set as long as it is 14 seconds or less). Driven,
Also, the light emitting unit 8 of the lantern L selected from the remaining lanterns.
Is driven by a sine wave whose one cycle S2 is 6 seconds (may be set to any value as long as it is 14 seconds or less), and the light emitting unit 8 of the remaining lantern N has one cycle S3 of 14 seconds. The control device 9 is provided with a first control means 21 and a second control means 22 so as to be driven by a sine wave of seconds (may be set to any value as long as it is 14 seconds or less). I have. Therefore, the light emitting section 8 of the lantern M is controlled by the first control means 21 as shown in FIG.
When the lanterns M and N are driven by the two sine waves shown in FIG. There are lanterns with different luminances, and the luminances of the lanterns change with the passage of time. By making the periods 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 or change the phase in the same period. Although the lanterns T are divided into three groups M, L, and N, the lanterns T may be divided into two or four or more groups.
It should be noted that the greater the number of groups, the more advantageous for the light effect. In FIG. 6, the peak value of the current is 3 A (ampere), but any value may be set. Although FIGS. 5A and 6 show an example in which the luminance is changed, the effect of light may be enhanced by changing the color. Also, as shown in FIG.
The use of a sine wave as a drive signal has the advantage that the luminance of the light emitting section 8 is gradually changed, so that the fluctuation of the candle flame can be expressed more realistically. be able to. Alternatively, the lighted 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 amount of received light.
