Description

DETAILED DESCRIPTION OF THE INVENTION The present invention-1 relates to an illuminated display device using fine optical fibers as a light guide, and more specifically relates to an original illuminated display device whose illumination effect changes in synchronization with changes in sound. -It is.

2. Description of the Related Art A display device is already known in which an optical fiber is used as a light guide, the distal end of the optical fiber is attached to a display body, and the proximal end is positioned near a light source, and the display device is illuminated by light from the light source. Many of the light sources of these display devices use rotating color filters, etc., and the color change ends after one rotation, and this process repeats after that, which is why it has been pointed out that there is little change. As a way to overcome this problem, a decorative object that changes color according to changes in surrounding sounds has already been proposed in Japanese Patent Laid-Open No. 50-97462. One method proposed in this bulletin is to divide the changes in electrical signals corresponding to the pitch of the sound into independent signals on the frequency component side using a bandpass filter, etc., and then turn on the corresponding light source. However, when using this method, if the frequency components of the sound collected by the micro-main are multiple sounds, a light source that emits monochromatic light is placed on each line so that the output can be obtained from the number O lines. However, there was a problem that the change in light was not noticeable because it was mixed to produce a large amount of light or light of multiple colors.

In view of the current situation, the present invention attempts to provide an illuminated display device tube that changes color in response to changes in sound, and the gist thereof is to use optical fiber as a light guide. In an illuminated display device, the light emitted from the light source is adjusted according to the strength of the sound. The present invention provides an illuminated display device characterized in that it is provided with a mechanism for extracting a signal, and a lateral mechanism that sequentially lights up a number of light sources of different colors depending on the extracted signal.
