Description

The present invention relates to an aurora rendering device.

  What is currently known as an amusement facility is an experience-type (experience-type) attraction in which a player (user) visits a low-temperature room whose temperature has dropped to below -30 ° C. This low-temperature room is cooled to a predetermined temperature (about -30 ° C) with a cooler, and a passage for players to pass through is provided along with the scenery and appearance of the Arctic and Antarctic regions. ing. For example, animal stuffed animals such as polar bears and penguins are installed, and ice columns made of resin are provided.

In order to make this attraction more interesting, it is conceivable to express the aurora in a pseudo manner. However, there is currently no device that produces a simulated aurora. Therefore, it is conceivable to use a visual simulator by a video projector (projector) to express a pseudo aurora. That is, an apparatus that projects on a screen using a video projector that captures an actual landscape image (actual aurora image) is conceivable (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 7-581

However, in this attraction, it is necessary to project the aurora image in an environment of -30 ° C. When a video projector is used, the device cannot withstand -30 ° C and becomes inoperable. It is impossible to express the aurora neatly.
Although a device that emits light using glass fiber without using a video projector is conceivable, it is a curtain (film) that is unique to aurora and cannot express vertical stripes well, and furthermore, frost is generated in the fiber and light is emitted. It was impossible to see the color clearly.

An aurora rendering device according to the present invention is an aurora rendering device provided in a low temperature room of −35 ° C. to −15 ° C., and has a screen and a large number of green and blue LEDs, and projects light onto the screen. A slit wall provided with a plurality of vertical slits provided on the light projecting side of the projector, and a mirror provided between the projector and the slit wall and rotating or swinging about a vertical axis. It is provided.
And a blocking wall provided between the slit wall and the screen and configured to block the lower edge of the light projecting path from the projector so that the shape of the lower edge of the projected image is an uneven waveform. It is a thing.
Further, the projector is connected to a dimming controller that turns on the green LED and the blue LED alternately and controls the luminance of the green LED and the blue LED to increase or decrease.
Moreover, it is preferable that the projector, the slit wall, and the mirror body are configured as one unit.
The unit is disposed at two positions on the left and right sides with respect to one screen, and each unit is covered and hidden by a hidden wall on the rear side of the unit.

According to the aurora rendering device of the present invention, a curtain-like vertical stripe pattern is projected by a plurality of vertical slits, and the amount of light on the screen is continuously changed by rotating or swinging the mirror body. Pseudo-aurora projection image with flickering and random (irregular) motion is obtained. Therefore, it is possible to produce a pseudo aurora full of realism that can be mistaken for an actual aurora.
Further, the skirt (lower edge) of the pseudo aurora can be expressed in a curved shape by the action of a shadow by the blocking wall, and a curtain-like three-dimensional image can be obtained like an actual aurora.
If the projector is always turned on, the projector never gets frosted due to the heat generated by the projector itself, and the apparatus can be provided in a low temperature room of −30 ° C. Moreover, even if it is always lit, the power consumption is small because the LED is used.

  FIG. 1 is a plan view showing an embodiment of a cold room 1 in which the aurora rendering device of the present invention is provided. The cold room 1 is cooled to a predetermined temperature by a cooler, and a passage (guideway) 12 through which a player passes is provided to reproduce the scenery and appearance of the Arctic and Antarctic regions along the passage 12. For example, stuffed animals such as polar bears, reindeers and penguins, dolls, models, etc. are installed, and ice pillars etc. that are made of resin and illuminate light with LEDs from below are provided.

  And in order to make this experience type (experience type) attraction more interesting, an aurora effect device that simulates the aurora in the middle of the passage 12 is provided. In addition, the arrow I shows the entrance direction into the low temperature chamber 1, and the arrow O shows the exit direction. Reference numeral 27 denotes an outdoor unit for a cooler. The inside of the low temperature chamber 1 is set to −35 ° C. to −15 ° C., and the aurora rendering device is provided in the low temperature chamber 1.

  As shown in the partially broken perspective view of FIG. 2 and the plane model diagram of FIG. 5, the aurora rendering device is provided on the screen 7, the projector 3 that irradiates the screen 7 with light, and the light projecting side of the projector 3. The slit wall 4 and the mirror body 6 provided between the projector 3 and the slit wall 4 are provided. Further, this apparatus is preferably provided with a blocking wall 8 provided between the slit wall 4 and the screen 7 and blocking the lower edge of the light projecting path from the light projector 3.

  The screen 7 can be configured by a white board or a white banner provided on the inner wall surface at a predetermined position of the low temperature chamber 1. Note that the screen 7 is not limited to a vertical planar shape, and may be configured to have a concave-convex waveform in a plan view ---- a concave-convex waveform that undulates in the left-right direction--which allows a three-dimensional appearance. A pseudo aurora can be expressed on the screen 7.

As shown in FIGS. 3 and 4, the projector 3 is an illumination device that irradiates light toward the screen 7, and includes a large number of green and blue LEDs (light emitting diodes) 2. In addition to the green LED 2a and the blue LED 2b, a large number of red LEDs may be included, and a large number of LEDs 3 of the three primary colors of light may be provided.
The light emitter 3 has a main body portion 17 in which a large number of LEDs 2 are arranged on the same surface in an array or randomly (irregularly) to form a panel, and the main body portion 17 having a large number of LEDs 2. And a stand portion 18 that supports the main body portion 17.

The light emitter 3 can be turned on and off by continuously changing the luminance (light quantity) by the function of the dimming controller 9.
In other words, the dimming controller 9 is connected to the projector 3, and the dimming controller 9 alternately turns on the green LED 2a and the blue LED 2b and increases or decreases the luminance of the green LED 2a and the blue LED 2b. It is a device that controls to change (fade in and fade out). Thereby, the green pseudo aurora and the blue pseudo aurora can be expressed alternately.
In addition, the light projector 3 can use the illuminating device which has LED of the three primary colors (RGB) of light for illuminating structures conventionally used, such as a building and a bridge, and this has a weather resistance. It is possible to continuously change the amount of light of each color.

  As shown in FIGS. 2 and 5, the slit wall 4 is provided on the light projecting side of the projector 3 and has a plurality of vertical slits 5 formed therein. It is arranged in the form of a (vertical lattice), and light is irradiated from the gap. In the illustrated slit wall 4, a plurality of bar members 19 are linearly arranged at equal intervals in the left-right direction. The bar member 19 is, for example, opaque (black) and made of acrylic resin. Although not shown, the slit wall 4 may be configured to slowly reciprocate linearly in the left-right direction so that the pseudo aurora fluctuates.

In the cross-sectional plan view of FIG. 6, the bar member 19 has an elongated rectangular cross section, the thickness dimension t in the left-right direction is 2 mm to 5 mm, and the width dimension W in the front-rear direction is 15 mm to 25 mm. Further, the gap G between the bar members 19 (the dimension of the vertical slit 5) G is set to 6 mm to 15 mm. Thereby, the rigidity of the bar member 19 is not impaired, the slit wall 4 can be formed with a predetermined interval G, and light is blocked with an appropriate interval G, so that a beautiful vertical stripe pattern can be expressed.
Note that the front-rear direction is the direction of irradiation by the projector 3 (the direction of arrow B in FIG. 6), and the orthogonal direction is the left-right direction.

Next, the mirror body 6 is provided between the projector 3 and the slit wall 4 in FIGS. 2 and 5 and rotates around the vertical axis C or swings around the vertical axis C (not shown). It is comprised as follows.
The apparatus of the present invention includes a motor 20 and a speed reducer 21 that rotate the mirror body 6 at a rotational speed of about 3 to 10 rpm.

The mirror body 6 has a shape of an elongated cross section in plan view, and the width dimension E in the longitudinal direction of the mirror body 6 is set to be smaller than the width dimension F of the projector 3 (E <F). The width dimension K of the slit wall 4 is set larger than the width dimension F of the projector 3 (F <K).
The mirror body 6 includes, for example, a mirror plate formed on the surface of a vertical plate member as shown in FIG. Further, in FIG. 2, two plate members are assembled back and forth with the rotation shaft 25 interposed therebetween, and the mirror body 6 is formed as a mirror surface on both sides.
As another form, the mirror surface may be a concave or convex surface or a corrugated waveform, and the whole has a shape of an elongated cross section in plan view.

  The blocking wall 8 is provided between the slit wall 4 and the screen 7, and blocks the lower edge of the light projecting path (beam) from the projector 3 and projects the lower edge of the projected image projected onto the screen 7. 2 and 5 are fixed vertical plate members in FIGS. 2 and 5. The upper end of the blocking wall 8 is slanted from side to side and is formed into a corrugated shape. Therefore, the lower edge of the light that has passed through the slit wall 4 from the projector 3 is blocked by an inclined waveform by the action of the shadow picture, and the lower edge of the pseudo aurora is expressed in an inclined shape and waveform on the screen 7 in a three-dimensional manner. Looks like.

  The blocking wall 8 may be a non-transparent (black) fixed plate member, but although not shown in the drawings, the blocking wall 8 is spirally formed as the blocking wall 8 on the outer periphery of a horizontal shaft that is rotatable by a motor and a speed reducer. A plate member may be provided. That is, when the blocking wall 8 rotates with the rotation of the shaft, the waveform of the lower edge of the pseudo aurora projected on the screen 7 can be reproduced as if it fluctuates.

Next, the operation of this aurora rendering device will be described with reference to FIG. A large number of green LEDs 2 a and blue LEDs 2 b are arranged on the light projecting surface of the projector 3 so as to be scattered in the vertical direction and the horizontal direction. That is, as shown in FIG. 5, it is considered that the green LED 2a and the blue LED 2b are alternately arranged in the left-right direction (the symbol a in the projector 3 indicates the green LED 2a and the symbol b is blue). LED2b is shown).
When these are alternately turned on by the operation of the dimming controller 9 (not shown), the light emitted from the adjacent green LED 2a or blue LED 2b and passing through one vertical slit 5 is transmitted to the screen 7 Since the light is irradiated with slightly shifted positions in the left and right directions, the pseudo aurora can be given a flicker by being alternately lit (illuminated) while automatically adjusting light. Furthermore, a curtain-like atmosphere can be expressed by the vertical slit 5.

Then, by rotating (swinging) the mirror body 6, the light from the projector 3 is partially blocked while the mirror body 6 is shaded to change the blocking area, thereby reducing the amount of light, and Since the amount of light reflected by the mirror 6 is partially changed (increased) while moving the reflection position in the direction of the screen 7, it is possible to give subtle and random (irregular) flickering of light. it can.
Also, the dimming controller 9 causes the green LED 2a and the blue LED 2b to fade in and fade out, and when the light intensity of one LED 2 becomes weaker, the light intensity is alternately turned on and off so that the other light intensity becomes stronger. The system pseudo aurora and the blue pseudo aurora can be expressed alternately.

  In FIG. 5, the right side (from the projector 3 to the slit wall 4) is a plan view, but the other left side is a view seen from the front in the direction of the screen 7 (in the horizontal direction in FIG. 5). The broken lines indicate vertical stripes, and the density of the hatched pitches (roughness of the hatched pitches) indicated by the broken lines indicates the color shade. In other words, according to the present invention, it is possible to represent a pseudo aurora in which color shades continue in the left-right direction while changing between green and blue, and the color changes every moment.

The projector 3, the slit wall 4, and the mirror body 6 are configured as one unit U. Furthermore, as shown in FIG. 2, the projector 3, the slit wall 4, the mirror body 6, and the blocking wall 8 may be configured as one unit U.
Specifically, a box 23 having a front wall as a slit wall 4 is formed on a horizontal substrate 22, and a stand portion 18 (not shown) of the projector 3 is fixed to the rear of the box 23, and The mirror body 6 is disposed between them. And the board | substrate 22 is made into the front-projection shape rather than the box 23, the blocking wall 8 is attached to the front-end part, and these can be handled integrally.

  The size of the unit U is such that the width dimension of the substrate 22 is 180 mm to 250 mm, and the depth dimension from the front end portion where the blocking wall 8 is provided to the rear end portion where the projector 3 is provided is 350 mm to 450 mm. In addition, the slit wall 4 is preferably provided in a substantially central part (range of 40 to 60%) in the front-rear direction.

  FIG. 7 is a plan view of a portion of the low temperature chamber 1 where the aurora rendering device is provided. The unit U is disposed at two positions 10 and 10 on the left and right sides with respect to one screen 7. Each unit U is covered and hidden by a hidden wall 11 on the rear side of the unit. That is, the unit U is disposed between the screen 7 and the passage 12, and the vertical wall-like hidden wall 11 is erected on the rear side, which is the passage 12 side of the unit U, so that the unit U can be seen from the passage 12. Is not configured. Furthermore, if imitation forest is arranged by a plurality of (white) Christmas trees in the front space portion 24 of the screen 7, an aurora that appears beyond the forest (with snow) can be expressed.

  A dimming controller 9 is connected to the projectors 3 and 3 of these units U and U, and controls to change the color (color development) by shifting the time between one and the other. Thereby, instead of expressing the same pseudo aurora on the left and right, the pseudo aurora of different colors can be expressed by shifting the left and right timing, and a more realistic and three-dimensional effect is possible.

  Further, as shown in FIG. 1, a pseudo aurora may be expressed by providing a screen 7 on the wall surface 13 of the straight passage portion 14 (although it is somewhat meandering) among all the passages 12. This allows players coming from the upstream side of the straight passage section 14 to show the pseudo aurora expressed on the downstream side from a distant position, allowing them to be recognized as an aurora appearing far away in the sky, and more A fantastic atmosphere can be produced.

  As described above, according to the present invention, the aurora rendering device is provided in the low temperature chamber 1 at −35 ° C. to −15 ° C., and has a screen 7 and a large number of green and blue LEDs 2. A light projector 3 for irradiating light, a slit wall 4 formed on the light projecting side of the light projector 3 with a plurality of vertical slits 5, and provided between the light projector 3 and the slit wall 4 and rotated around a vertical axis. And a mirror body 6 that swings. A curtain-like vertical stripe pattern is projected by the plurality of vertical slits 5, and the amount of light on the screen 7 is continuously increased by the rotation or swinging of the mirror body 6. Therefore, a pseudo aurora projection image that is fantastic, fluctuates randomly (randomly), and flickers is obtained. Therefore, it is possible to produce a pseudo aurora full of realism that can be mistaken for an actual aurora.

  Further, if the projector 3 is always turned on, the projector 3 never gets frosted due to the heat generated by the projector 3 itself, and the apparatus can be provided in the low temperature chamber 1 of, for example, −30 ° C. Moreover, even if it is always lit, the power consumption is small because the LED 2 is used.

  Further, a blocking wall 8 provided between the slit wall 4 and the screen 7 and configured to block the lower edge of the light projecting path from the projector 3 so that the shape of the lower edge of the projected image has an uneven waveform, Since it is provided, the skirt (lower edge) of the pseudo aurora can be expressed in a curved shape by the action of the shadow by the blocking wall 8, and a curtain-like three-dimensional image can be obtained like an actual aurora. .

Further, the projector 3 is connected to a dimming controller 9 that alternately turns on the green LED 2a and the blue LED 2b and controls the luminance of the green LED 2a and the blue LED 2b to increase or decrease. The light projected from the adjacent green LED 2a or blue LED 2b and passing through one vertical slit 5 is slightly shifted in the left-right direction on the screen 7, so that the alternate aurora gives flickering to the pseudo aurora. Can do.
Also, the dimming controller 9 causes the green LED 2a and the blue LED 2b to fade in and fade out, and when the light intensity of one LED 2 becomes weaker, the light intensity is alternately turned on and off so that the other light intensity becomes stronger. The system pseudo aurora and the blue pseudo aurora can be expressed alternately.
