Description

  The present invention relates to a photoelectric decoration device using an LED lamp designed on the premise that a dancer or a spectator wears or holds in a hand at a stage, a mass game, an event venue, or the like. This photoelectric decoration device is equipped with a motion sensor, and is characterized by automatically creating and displaying an effective photoelectric decoration image that responds quickly to the movement of the body.

  A so-called lumitube is formed by stringing LED lamps in a string, and is widely spread as a photoelectric decoration device by forming it in a standing tree or by forming it into various shapes. Also, in recent years, in the stage of events such as concerts, besides illuminating equipment as a fixed stage device, a stage where characters such as singers wear LED lamps on crowns, clothes, etc. as well as beads and sequins. Wearable photoelectric decoration devices for increasing the decoration effect of costumes are also appearing. However, each LED of these conventional wearing type photoelectric decoration devices is merely lit or flashed with a specific emission color for a certain period of time.

For these conventional photoelectric decorations, for example, by using a ream LED module (Patent Document 1), the luminance data (hereinafter referred to as “illuminated video”) is read from each LED lamp in advance in a ROM, etc. By doing so, a more sophisticated and more effective wearing type photoelectric decoration device can be realized.

Japanese Patent Laid-Open No. 2004-070179

  The ROM built-in wearable photoelectric decoration device, such as the wearable photoelectric decoration device using the above-mentioned multiplying slot method, not only displays a fixed illumination video, but also displays various illumination scenes on the stage, or Greater illumination effects can be obtained by changing the wearer in response to various movements.

  In this way, diversifying the electric video to be displayed means that a plurality of different electric video is stored in the ROM in advance, and the wearer is equipped with the wearing type photoelectric decoration device according to gesture or music. It can also be realized by operating the operation keys to select and display them. (Patent Document 2).

  However, in the method of storing a large number of illumination pictures in the ROM in advance, as the number increases, the capacity of the ROM increases and the complexity of the wearer's selection operation becomes a bottleneck. In addition, it is necessary to prepare a lighting image that can respond to various scenes in advance and store it in the ROM, which requires a lot of work and cost.

In the present invention, the wearable musical instruments such as castanets, bells, and tambourines have a simple structure, but play a variety of music that responds instantly to the dancer's movement. Incorporating a mechanism to detect the movement of the device such as an acceleration sensor in the system and receiving the output automatically selects an illumination image, or automatically generates a new illumination image, which is higher with a simple mechanism and simple operation. A wearable photoelectric decoration device that creates a decorative effect is realized.

  Examples will be described below.

  "FIG. 1" is an example of a wearable photoelectric decoration device in which LED lamps (1a) are arranged in a triangle shape and a dancer dances with a grip (1b) protruding from below. In the hand grip (1b), electronic components necessary for the present device: a battery, a motion sensor, a ROM, a control circuit, and the like are housed.

  “FIG. 2” is a system diagram of this apparatus. First, ROM (2b) stores lighting / non-lighting information for each LED lamp for each frame period as 1-bit data corresponding to each frame so that each LED lamp of the display section (2e) blinks randomly. ing

“FIG. 3” exemplifies the bit data corresponding to one LED lamp. The horizontal axis is the time axis in units of the frame period, and the vertical axis is the lighting status in each frame, that is, when the bit data corresponding to each frame is “1”, lighting in that frame, when “0” Represents non-lighting, and the lighting time widths T ₀ , T ₁ , T ₂ ... And the non-lighting time widths W ₀ , W ₁ , W ₂ . Uniformly distributed).

  This is (2a) motion sensor in FIG. As the motion sensor (2a), a magnetic sensor type that detects a change in geomagnetism, an acceleration sensor type that detects a strain applied to a specific member, and the like are known as small and inexpensive sensors (Non-Patent Document 1).

  The motion sensor (2a) in the present embodiment is designed to detect an acceleration of a certain magnitude or more and to digitally output the magnitude. The digital output (2f) of this motion sensor is used as a trigger to start reading bit data (2g) to each LED lamp stored in the ROM, while the read bit data (2g) 2c) is converted into frame luminance data (2h) proportional to the magnitude (of detected acceleration) of the digital output (2f).

  Each LED lamp is controlled to be lit by the multiplying slot type luminance control circuit (2d) with frame luminance data (2h) corresponding to the LED lamp for each frame period. That is, in the sub-frame corresponding to each bit of the luminance data provided in each frame period, lighting and non-lighting are controlled by the sub-frame data (2i), which is proportional to the frame luminance data (2h). Lighting control is performed with visual brightness.

  The magnitude of the acceleration detected by the motion sensor (2a) is also used for controlling the duration of the lighting control operation time. That is, the time width of the blinking operation that starts with the digital output (2f) of the motion sensor as a trigger is also controlled to be proportional to the magnitude of acceleration, that is, the magnitude of the digital output (2f) of the motion sensor (2a).

   In this way, the digital output that is output when the motion sensor detects an acceleration of a certain level or more serves as a trigger for reading the bit data in the ROM, and at the same time, the conversion magnification from the bit data to the luminance data, and from the start of reading. Determine the time span until the end.

  With the above-described mechanism, the wearable photoelectric decoration device according to the present embodiment can create an excellent illumination effect that responds quickly to the wearer's movement, such that if it is shaken more strongly, it will continue flashing with stronger light for a longer time.

In addition to the embodiments described above, the following mechanism may be adopted.
(1) The basic luminance signal uses an electronic circuit such as a random bit data generation circuit instead of the bit data stored in the ROM.
(2) In addition to the acceleration sensor described above, a type of sensor that detects the direction of movement and rotation, or detects the position itself by GPS or the like is used as the motion sensor.
(3) An operation key is provided in addition to the motion sensor. For example, an illumination video to be displayed is changed by a combination of the motion sensor output and the operation key output, such as changing the emission color by the operation.
(4) A wearable photoelectric decoration device equipped with a motion sensor is combined with a musical instrument that emits sound by movement, such as a bell or castanets, and emits sound and light in response to movement.
(5) Combining a wearable photoelectric decoration device equipped with a motion sensor and a music generator using electronic means controlled by the motion sensor (timing, tone, size, etc.) And emit light at the same time.

In addition to being worn by humans;
(1) Attached to the animal body, such as an animal collar,
(2) Attached to moving machinery such as bicycles, wheels of children's tricycles, and swings, etc.
(3) Installed on windmills, wind chimes, waterwheels, lanterns, etc., wind, water currents, machines that move using waves, equipment, and ornaments.
The same photoelectric decoration effect can be exhibited.
