Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an in-ice light emitting device, and particularly to a decorative ice wall surface of an ice skating rink, a hotel lobby, etc.
This invention relates to an in-ice light emitting device that is applied to ice decorations, ice sculptures, etc. using icicles.

[Background of the invention]

In recent years, due to the diversification of the leisure industry, it has become difficult for recreational ice skating rinks to attract sufficient customers with conventional rinks that simply skate. In other words, at ice skating rinks that are mainly used for commercial purposes, they not only try to improve the quality of the ice on the rink, but also add various features to the rink, such as adding various patterns to the ice and adding ice from the outside. They also put materials in the ice that reflect the rays of light. Furthermore, even in ice skating rinks for sports competitions, the in-ice coloring method is used for track lines for speed skating, lines for competitions such as ice hockey, etc.
In addition, attempts are being made to enhance the entertainment value of indoor ice skating rinks by using laser lights, cocktail lights, mirror balls, etc. to illuminate the space above the ceiling.

One possible method for emitting light in ice is to bury light emitting means such as light bulbs in the ice and turn them on. However, such a light emitting means requires waterproof measures for the light source, and the heat from the light source increases the ice temperature, causing the ice to melt. Furthermore, when skaters jump on the ice skating rink or a rink cleaning vehicle passes by, an excessive load is applied to the light source, which may damage light bulbs and the like.

Furthermore, since the light is emitted inside the ice, there is a risk that the light emitting effect sufficient for decoration may not be obtained depending on the transparency of the ice, the type of lighting in the room, the brightness, etc. .

Furthermore, for an in-ice light emitting device, it is conceivable that a heat insulating material is laid on a foundation floor, the light emitting source is placed on top of the heat insulating material, water is gradually frozen in a cooling pipe, and the material is fixed with ice. However, if you simply place the light source on the floor like this, as the ice hardens, the light source's irradiation surface will bend, and the spacing between the light sources will shift, making it difficult to visualize the design you were trying to depict. The problem was that the images were distorted and lacked sharpness. Normally, at an ice skating rink, it takes about a week to complete the skating surface. Therefore, even if the light emitting source shifts or bends in the ice, making the intended design or pattern unclear or deformed, it is not recommended to reinstall it. This is not possible unless the entire surface of the ice skating rink is melted.

In addition, with such a light emitting device, for example, in the case of an incandescent bulb, there is a lot of light scattering in the ice, and most of the light emitted is scattered in the ice, making it extremely difficult to draw patterns, straight lines, etc. This results in an inefficient light emitting device. Another drawback was that if there was too much scattered light in the ice, it became impossible to distinguish the patterns that the researchers had worked so hard to draw.

Furthermore, the in-ice light emitting device is used not only for ice skating rinks but also for decorative ice. Decorative ice is used to add interest to wedding halls, various events, festivals, etc. Even with such decorative ice, the same problems as in ice skating rinks arise, such as melting of the ice and visibility of the light emitters.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a skating rink that is suitable for the purpose of recreational sports of enjoying the atmosphere by adding entertainment to conventional skating rink lighting.

[Summary of the invention]

To achieve this object, the present invention is characterized in that a light emitting source is disposed within the ice layer, and the light transmitted from the light source emits light onto the ice surface of the rink.

That is, the present invention focuses on the fact that the ice layer in a skating rink is transparent, and is characterized in that the light transmitted through the ice layer, emitted from a light emitting source disposed within the ice layer, produces a soft and unique color tone. There is.

In addition, the present invention utilizes LED as a light emitting source in ice.
(Light Emitting Diode), this LED is installed in advance on a mounting block, and this LED-equipped block is installed on a concrete floor surface. LEDs generate less heat, so there is no risk of ice melting, and no special measures are required for waterproofing.

Further, the present invention is a method of developing color from within the ice of an ice skating rink by installing an incandescent bulb in a translucent tube and embedding this tube in the ice to generate color. By arranging the incandescent bulb in this transparent tube, the incandescent bulb becomes completely waterproof and the installation work becomes easy.

[Embodiments of the invention]

Preferred embodiments of the in-ice light emitting device according to the present invention will be described in detail below with reference to the accompanying drawings.

Figure 1 shows the schematic structure of an in-ice light emitting device when main turning is performed using an LED as a light source. As shown in FIG. 1, cooling pipes 12 are arranged at predetermined intervals within the concrete floor 10, and a refrigerant is passed through the cooling pipes 12. concrete floor 10
A wire mesh 14 is arranged on the upper surface of the LED mounting block 18, and LED mounting blocks 18 are provided at predetermined intervals on the wire mesh 14 through L-shaped angle members 16.

This block 18 is made of transparent acrylic resin, and has a hole 20 formed in its center as shown in FIG. This punch hole 20 is constructed so that when the block 18 is laid on the concrete floor 10, the block 18 does not interfere with the transmission of cooling heat from the cooling pipe 12. Extraction hole 2
As shown in FIG. 3, a recess 22 is formed on both sides of the LED mounting hole 2.
4 is formed. LED26 is block 18
The LED is inserted into the recess 22 and the mounting hole 24 from the bottom of the block 18, and is attached to the block 18 with, for example, acrylic adhesive 28, as shown in FIG.
The upper part of block 26 is attached so as to be exposed from block 18 as shown in FIG.

Since the block 18 is installed along the angle member 16, it can be installed accurately at a predetermined position without bending or wobbling. Also angle material 16
is attached to a wire mesh 14, which evenly distributes the cooling heat from the cooling pipe 12, and
Without locally accumulating heat from LED26,
It has the function of dissipating.

After installing the LED block 18 in this way, an ice layer 30 is formed. This ice layer 30 is 50
It is formed to a depth of ~80 mm, and its formation method is to pass the refrigerant into the cooling pipe 12 and to cool it at a depth of 2~3 mm at a time.
The ice layer 30 is formed by withdrawing water to a thickness of . In this way, if the amount of water withdrawn at one time is 2 to 3 mm thick, the ice layer will be 30 mm thick.
Eliminating the generation of air bubbles during the formation process, increasing the strength of the ice layer 30 and increasing the transparency of the ice layer 30,
This is to make it easier for light from the LED 26 to pass through.

Next, the mounting intervals of the LEDs 26 will be explained.
In Figure 4, if the illuminance on the ice is 150L _UX , the ice surface temperature is -2℃, and the ice layer depth D is 50mm, the LED irradiation angle θ will be 10 to 20°, and therefore the pitch will be
It will be 30mm. As a result, when viewed from above the ice, if the LEDs are installed within the pitch, the light from the LEDs will appear continuous.

Figure 5 shows an example of temporary construction work for an ice skating rink. Temporary construction is used, for example, when a pool, gymnasium, etc. is used as an ice skating rink in the winter. In the case of a temporary ice skating rink, a heat insulating material 34 is placed on the concrete floor 32 as shown in FIG.
Cooling pipes 12 are provided on the top at predetermined intervals. Further, a wire mesh 14 is laid over the cooling pipe 12, and L-shaped angle members 16 are provided on the wire mesh 14 at predetermined intervals. This L-shaped angle member 16 has the LED 2
A block 18 is provided, on which a block 6 is attached. In this way, a temporary ice skating rink can be constructed. The method for forming the ice layer 30 is repeated a predetermined number of times in the same way as in the case of the main lathe, with the amount of water withdrawn at one time being 2 to 3 mm deep.

6 to 8 show examples of the arrangement of the LED mounting blocks 18 on the link. FIG. 6 is a plan view of the skating rink, in which a large number of mounting blocks 18 are arranged over the entire surface of the rink surface 36. These LED mounting blocks 18 are connected to a controller to be described later, and by individually controlling blinking, it is possible to draw various light patterns and change the color tone. Color effects can also be enhanced by combining light and music. Figure 7 is a plan view showing the case where it is applied to a speed skating rink, and Block 1
8 is disposed over the entire sliding surface of the speed link 38. These blocks 18 are interlocked with a controller (not shown), and can function as a pacemaker for the runner by sequentially blinking in the circumferential direction of the speed link 38 and controlling the blinking movement speed. FIG. 8 shows an example of the use of a multi-purpose link, in which blocks 18 are arranged along the sliding surface of the speed link 36, and are arranged in patterns such as flowers, animals, birds, etc. With this arrangement, the rink can be used for multiple purposes by lighting up the LED mounting blocks 18 depending on the purpose, whether for entertainment or speed skating.

FIG. 9 shows a case where a mini incandescent bulb is used as a light source. Mini incandescent bulbs 42 are arranged within the transparent tube 40 at predetermined intervals. The mini incandescent bulbs 42 are connected in series to sockets 44 by covered wires 46. The mini incandescent bulb 42 is coated with a predetermined color and emits various colors when lit. In the case of main turning, the transparent vinyl chloride tube 40 containing the mini incandescent bulb 42 is constructed by laying a wire mesh 14 on a concrete floor 10 on which cooling pipes 12 are installed, as shown in FIG. U-shaped rail 48 on top
A vinyl chloride tube 40 is attached via the . In addition, in the case of temporary construction work, as shown in Figure 11.
Similar to LED, insulation material 3 on concrete floor 32
A cooling pipe 1 is provided above the heat insulating material 34.
2, and a U-shaped rail 48 is attached onto this cooling pipe 12 via a wire mesh 14. A transparent vinyl chloride tube 40 containing a mini incandescent bulb 42 is mounted inside this U-shaped rail 48.

By arranging the mini incandescent bulb 42 in the vinyl chloride tube 40 in this way, the mini incandescent bulb 42
It eliminates the need for waterproofing measures, and is also strong against pressure from the ice, eliminating the risk of damage. In addition, the mini incandescent bulbs 42 are not directional like LEDs, and the light is scattered around. However, if the U-shaped rail 48 is configured as a reflective surface, the light will be reflected upwards and will be clearly visible on the ice. The image begins to emerge. Also, as shown in FIG. 9, a fan 50 is installed inside the tube 40.
The heat accumulated in the tube 40 can be removed by supplying air from the tube 40 and exhausting the air from the other end of the tube 40. When using the mini incandescent bulb 42, the mini incandescent bulb 42 itself may be coated with a color, but the transparent vinyl chloride tube 40
It is also possible to color it and make it emit light.

If the spacing between the mini incandescent bulbs 42 is too narrow, the amount of heat generated will increase, resulting in a problem that requires increased cooling capacity. In this case, the lines of the planned pattern will be cut off, making it impossible to achieve the initial goal. Figure 12 shows an example of this experiment, where the illuminance on the ice was 150L _UX and the surface temperature was minus 2℃.
If the ice depth D=50 mm, the irradiation angle θ of the mini incandescent bulb 42 will be 20 to 40 degrees, and the pitch will therefore be about 60 mm. Pitch 60mm like this
If set to a certain level, the cooling capacity is minimal and a predetermined pattern can be made to appear on the ice.

In the case of an in-ice light emitting device, when mini incandescent bulbs 42 are used as the light source, the filament life span is several thousand hours, so disconnection after this time is unavoidable. In addition, in the case of a series connection, if a disconnection occurs, the light emitting sources are connected in series, so even if a disconnection occurs in one mini incandescent bulb, the current will be supplied to all the mini incandescent bulbs in the circuit. stops.
To avoid this, there is a method of connecting mini incandescent bulbs in parallel, but this method requires a large current to flow through the circuit and has the disadvantage of increasing the number of wires.

FIG. 13 shows an embodiment of the present invention made to solve such problems. A bypass circuit 52 is connected in parallel with the mini incandescent bulb 50. The bypass circuit 52 may be a resistor, as long as it can flow enough current to light up the mini incandescent bulbs 50 connected in parallel, and can also flow a current that can light up other mini incandescent bulbs in the event of a disconnection.
It may be any type of circuit, such as a circuit using a semiconductor element as a switch member, other elements, or parts.

FIG. 14 shows a specific example of the embodiment shown in FIG. 13. FIG. 14 shows the case where the power source is an AC power source, and the bypass circuit 52 is constituted by two Zener diodes 54 and 56 connected in opposite directions.

The Zener diodes 54 and 56 have the voltage-current characteristics shown in FIG. characteristics).

Therefore, if the mini incandescent bulb 50 is operated at a certain voltage V that is less than the Zener voltage Vz, a Zener current I flows through the Zener diodes 54 and 56 every half cycle of the AC power supply. This current I is minute, and a sufficient current flows through the mini incandescent bulbs 50 connected in parallel, so that in practical terms the Zener diodes 54 and 56 can be considered to be in a non-operating state.

In the circuit of Figure 14, the mini incandescent bulb 50
If A out of the four circuits (A, B, and CD) is disconnected, as shown in Figure 15, the voltage (V) across the bypass circuit 52 increases to exceed the Zener voltage Vz, and the mini incandescent bulb 50, the current flowing through the diode is equal to or higher than the Zener current Iz. However, due to the constant voltage characteristics of the Zener diodes 54 and 56, the Zener voltage Vz is maintained, and a current value similar to the current flowing through the mini incandescent bulb before the disconnection flows through the Zener diodes 54 and 56, making it practically conductive. Become. Therefore, if the Zener voltage Vz of the Zener diodes 54 and 56 is set to a value slightly higher than the operating voltage of the mini incandescent bulb 50, and the power capacity is set to a value that takes into account the safety factor for the power consumption of the mini incandescent bulb 50. Even if a disconnection occurs in the mini incandescent bulb 50, the circuit itself can be operated intermittently.

FIG. 16 shows another specific example of the embodiment shown in FIG. 13, in which the power source is a DC power source. In this embodiment, one of the Zener diodes is removed from the bypass circuit 50 shown in FIG. 14, and the cathode side is connected to the positive side of the power supply. Since alternation does not occur in direct current, only one Zener diode is required, and the method for setting the Zener voltage is the same as that shown in FIG. 14, so a description thereof will be omitted.

As is clear from the above, according to the present invention, a bypass circuit is connected in parallel to each of the light emitting sources such as incandescent bulbs that may be disconnected, so that the circuit continues even if an accident such as a disconnection occurs in the light source. It can be made to work.

In the ice light emitting device shown in FIG. 17, in the ice skating rink, cooling pipes 12 are buried inside the rink floor 10, and an ice layer 30 is formed. The in-ice light emitters are placed in the ice layer 30, and controlled by the controller 60, for example, in synchronization with music, the mini incandescent bulbs 42 inserted into the transparent tube 40 flash in a designed manner, creating a colorful leisure link. , blinks sequentially with a certain synchronization and is used as a pacemaker for speed skating. However, the luminescent elements in the ice are affected by the presence or absence of air bubbles in the ice, the cloudiness of the rink's surface, the surrounding illuminance, etc., and even with the same illuminance, the way the luminescent elements are seen by skaters and spectators can vary greatly. Figures 18 and 19 show the example of Figure 17 with a rated 28V as a light source,
This is a measurement of the relationship between the luminous diameter on ice, the illuminance on the ice, and the ice surface temperature when using a 25 mA mini color light bulb. As shown in FIG. 18, as the illuminance on the ice becomes darker, the diameter of the emitted light appears larger. Also, as shown in Figure 19, when the ice surface temperature falls, the rink surface becomes cloudy and the luminous diameter appears large, and as the surface temperature rises and the ice on the rink surface begins to melt, the luminous diameter decreases. The small size becomes clearly visible.

Therefore, when using an in-ice luminous body for line display at a hockey rink, or as a pacemaker for speed skating, it is necessary to keep the visibility from the skater to one side even when the ice temperature and on-ice illuminance change. When using the system, it is desirable to change the appearance of the light emitters in combination with changes in the lighting of the entire rink, changes in the music, etc.

An embodiment of the present invention made under such circumstances will be described based on FIG. 20. It should be noted that the same parts as in FIG. 17 are given the same numbers, so the explanation will be omitted. The temperature sensor 62 measures the rink ice temperature, and in this embodiment is buried at a position of 10 to 15 mm from the ice surface. Further, the illuminance sensor 66 measures the illuminance near the ice surface of the rink. The controller 64 controls the brightness of the mini incandescent bulb 42 via the regulator 68 based on the values of the temperature sensor 62 and illuminance sensor 66, and also controls the refrigeration device or illumination light (not shown). .
Based on the signal from the controller 64, the regulator 68 changes the power supply voltage to adjust the brightness when the in-ice light emitter is like a mini incandescent bulb, and adjusts the brightness by changing the power supply voltage when the in-ice light emitter is like a light emitting diode (LED). In such a case, the brightness is adjusted by changing the pulse width of the pulse drive (by changing the duty ratio).

Next, the operation of one embodiment of the present invention will be explained. When drawing lines for use as a multi-purpose ice skating rink using the in-ice luminous bodies 42, as shown in Fig. 21 a, b, c, and d, the luminous bodies are combined in accordance with various lines to form the ice layer. Bury it below. In this example, a high-brightness type light emitting diode is used as the in-ice light emitting body, and FIG. 21a is used for figure skating, FIG. 21b is used for ice hockey, and FIG. 21 is used for speed skating. Make the light emitting lines as shown in c and d. In the case of a figurine rink, the rink temperature should be set to around -3℃ and the illumination on the ice should be reduced.
When controlling to 500 to 600L _UX , clear line display can be achieved by controlling the repetition frequency of the pulse drive of the light emitting diode to 50Hz and the duty ratio to 50%. In addition, in the case of the hockey rink shown in Figure 21b, the rink temperature is -5℃ and the illuminance on the ice is
When controlling 1300 to 1500L _UX , a duty ratio of 5% provides a clear line display, and the same link can be easily used for multiple purposes. In addition, in the case of a leisure rink, we embed light emitters in the ice in various designs, lower the rink temperature to about -4℃, combine it with music, and change the illuminance on the ice from about 50 to 300L _UX . By changing the brightness of the in-ice luminescent body according to
You can create a variety of colorful and fantastical effects. It goes without saying that the in-ice light emitting device of the present invention can be used by being embedded inside an ice sculpture brought into a wedding hall or various event venues.

As described above, according to the present invention, the ice temperature and on-ice illuminance are measured and the brightness of the in-ice light emitter is controlled accordingly, so even if the ice temperature and on-ice illuminance change, the pacemaker for speed skating can be used. When used for such purposes, the way the lines are seen from skaters remains constant, and when used for leisure rinks, it is possible to change the way the in-ice light emitters are seen.

Next, FIG. 22 shows an example of an in-ice light emission control system used in an ice skating rink. The in-ice luminescence control system controls the blinking of luminescent bodies buried in the ice in synchronization with music and lighting from above the ice, or controls the blinking speed, switching the pattern to be drawn on the ice, and controlling the flow of light (direct flow). , reverse flow), etc., a music tuning section 72, and a relay unit 74 consisting of a group of relays for controlling power supply to a plurality of light emitters buried in the ice. ing.

The control unit 70 includes a main computer 80 that performs various calculation processes, and a keyboard 8 that is used to specify the number of pieces of music to be performed, the pattern to be drawn on the ice, etc.
2. It consists of a CRT 84 for monitoring, a memory 86 such as a floppy disk or bubble memory in which various programs and fixed data are stored, and switch control units 88 and 90.

Furthermore, the music tuning unit 72 is composed of a music performance computer 100, a floppy disk 102 storing performance data such as rhythms and melodies corresponding to the pieces of music to be played, and a synthesizer, etc., and plays back according to the melody and rhythm of the pieces to be played. A melody tuning unit 104 that creates a signal, a scale tuning unit 106 that includes a plurality of frequency filters and converts it into a digital signal according to the scale, and a sound pressure tuning unit that outputs a digital signal according to the intensity of the input sound. It consists of 108.

In the above configuration, when the music performance computer 100 inputs various data such as the number of songs to be played and various patterns to be drawn on the ice through the keyboard 82, the main computer 80 inputs the programs stored in the memory 86. Based on the music performance computer 100 in the music tuning section 72
and sends a control command to relay unit 74.

The music performance computer 100 reads performance data of the instructed performance piece from the floppy disk 102 based on the control command from the main computer 80, and outputs the data to the melody tuning unit 104. The melody and other tuning unit 104 creates a melody and rhythm according to the piece of music to be performed from the performance data, outputs the playback signal to the speaker 112 via the amplifier 110, and plays the music from the speaker 112 into the hall, and also listens to the performance. A synchronization signal for synchronizing the blinking operation of the light emitters, etc. with the melody and rhythm created from the data is output to the main computer 80 via the switch control unit 88.

The main computer 80 switches and controls signals for controlling the light emission of the light emitters so that the blinking speed of the light emitters, the flow of light, and the pattern to be drawn on the ice change in a predetermined order according to the timing of the synchronization signal. Based on the control signal, the relay unit 74 controls ON/OFF of each relay in the relay group connected between the light emitter and the driving power source via the unit 90, and controls the light emission timing, light emission order, etc. of the light emitter. is controlled.

On the other hand, a music performance computer 10 is used for music performance.
0 is not used, that is, when playing music from cable broadcasting, records, music tapes, etc., the playback signals from these are outputted to the speaker 112 via the amplifier 110, and are also output to the melody etc. tuning unit 104 and the scale tuning unit 106. and the sound pressure tuning unit 108, respectively.

As mentioned above, the melody tuning unit 104 sends a synchronization signal to control the light emission of the light emitters according to the melody and rhythm, and the scale tuning unit 106 and the sound pressure tuning unit 108 send out synchronization signals to adjust the scale and the strength of the sound, respectively. A corresponding digital signal is output to the main computer 80 via the switch control unit 88. Further, the output of computer music using a music performance computer is input to the scale tuning unit 106 and the sound pressure tuning unit 108, and it is possible to tune to the scale and strength of the sound of the computer music as described above.

Based on these output signals, the main computer outputs control signals for controlling the light emission of the light emitters to the relay unit 74 via the switch control unit 90.
