Description

[Detailed Description of the Invention] This invention relates to a lighting device for an electronic organ, particularly a large-sized electronic organ.

Large electronic organs, such as theater-type organs, are sometimes played in dimly lit places with limited lighting. It is necessary to illuminate the music stand) and the music stand, but conventionally, as shown in Fig. 1, lighting lamps l are separately attached to the upper end of the operation panel P of the instrument body E and the front end of the roof plate a. Each light illuminates the switch section S and the keyboard section k on the front of the instrument, and illuminates the musical score f on the roof board.

In order to prevent the irradiated light from each lamp l from directly entering the performer's eyes and to allow the light to reach the necessary areas appropriately, each lamp l is equipped with a blind C. The size of the device was too large, making it unsightly in appearance, and it was difficult to attach lighting to the single panel, which was packed with operating parts.

Therefore, this invention solves the above-mentioned drawbacks, and provides a lighting device that is easy to install, does not require large scale, and can illuminate the necessary areas appropriately without damaging the appearance. .

To explain the illustrated embodiment, referring to FIGS. 2 and 3, 1 is a lamp such as a fluorescent light or a light bulb attached to the center of the front end surface of the roof plate a of the main body E of the musical instrument. , 2 is a cover of a required length to cover this lamp 1, and as shown in FIG. 2a is tilted rearward downward, the rear end is stepped, and the cross section is almost trapezoidal, and buttons are attached to the ends of the upper and lower walls 2a and 2b, and are fixed to the upper and lower surfaces of the front end of the roof board a. There is.

A translucent plate body 3 a e 3 b of a required length made of glass or acrylic resin is attached to the upper wall 2 a and the lower wall 2 b of the cover 2 .

Therefore, when the lamp 1 is turned on during a performance, the light passes through the translucent plates 3a and 3b on the top and bottom of the cover 2 and reaches the music sheet f on the roof plate a and the switch section S on the front of the operation panel p. The buttons and keyboard part k are irradiated at the same time.

At this time, the light directed forward is blocked by the front wall 2c of the cover 2, so it does not directly hit the performer's eyes and does not interfere with the performance, and the light directed upward and downward is blocked by the light passing through the upper wall 2a. The translucent plate 3a on the lower wall 2b is oriented directly downward, and the front wall 2c is slanted rearward upward. This means that the musical score f and the switch section S1 on the front of the operation panel and the keyboard section k are appropriately illuminated.

In this case, it is convenient to make the rear end of the upper wall 2a of the cover 2 step-like as shown in the figure so that it can serve as a music stick, but it is not necessary to do so.
A separate music bar may be provided on the roof plate a.

FIG. 5 shows a modification in which a slit 4 having a required width and length is provided at the front end of the roof plate a, and a lamp 1 is mounted inside the slit 4.
The upper opening is covered with a cover γ consisting of a front wall 2c' inclined rearward upward and a mud wall 28' inclined rearward downward and equipped with a translucent plate 3a', and the lower opening is covered with a roof. Board a
Although it is covered with a transparent plate 3b' attached to the lower surface of the holder, its function is the same as in the above example.

As described above, in this invention, an illumination lamp is attached to the front end of the empty roof board, and the lamp illuminates the music section on the roof board, the switch section in front of the operation panel, and the keyboard below. Since the lights are illuminated at the same time, the scale of the lighting fixtures does not become too large compared to conventional lighting fixtures that are installed separately, and it is easy to set up and looks good without spoiling the appearance. Moreover, since the irradiated light is given directionality backward and downward, it is possible to properly illuminate the necessary areas and perform the performance without any problems.
