It consists of a system.

Description

[Detailed description of the device]

[001]

[Industrial applications]

 The present invention is a point-lighting stage effect production device for improving the atmosphere in small-scale restaurants such as snacks and small-scale banquets such as home parties.

[002]

[Prior art]

 Conventionally, as this type of point lighting stage effect production device, a large-sized device commonly called a mirror ball and a medium-sized but expensive computer-controlled laser beam projection device are known.

[003]

[Problems to be solved by this proposal]

 In the conventional technology, since the device is large and expensive and more flashy, it is difficult to use it in a small restaurant such as a snack or a small banquet such as a home party.

The present invention provides a small-sized and inexpensive point lighting stage effect production device for easily obtaining a production effect by point illumination of a laser beam.

[0095]

[Means, actions and effects for solving the problems]

 In order to achieve this purpose, the point lighting type stage effect production device of the present invention uses a semiconductor laser beam, so it is very compact and has a calming effect.

The laser light source (C) is fixed to the holding column (9) fixed to the box (2), and the optical axis is directed toward the center of rotation of the mirror (B). The number of laser light sources may be plural.

Although the rotation of the irradiation control mirror (B) in the horizontal direction is based on the conventional rotation technique, a servo system by a computer is not used for the vertical direction control, and the mirror (B) can be freely swung freely. It is fixed to the axis (8), the rest angle (a) of this mirror (B) is adjusted to around 55 degrees, and natural and accidental stimuli such as wind, vibration and contact are directly used as driving energy. By shaking it vertically, we made it possible to provide it at a very low price.

As shown in FIG. 5 (5), the effect is increased by changing the direction of two mirrors and fixing them on the same axis so that the number of laser light sources is two or more.

Also, since the fluctuations caused by natural and accidental stimuli are used, the movement of the light rays is natural, and the effect of comfort comes to the stage production.

[First Embodiment and Result] The first embodiment is a case where the present apparatus is hung and used, which will be described with reference to the drawings (1) to (3). The rotating device (A) is 5 r. p. 1.5m small motor in m, mirror (B) is 10 * 20mm, protrusion (5) is not attached, static angle (a) is 55 degrees, laser light source (C) is 2mW with lens .

This device was hung near the ceiling using the hanging tool (1), and the laser light was emitted from the laser light source (C) while rotating the rotating device (A).

[0112]

As a result, the dotted light of the laser light swirled while drawing a gentle and complicated curve due to the wind of the air conditioner.

[0113]

[Embodiment 2 and its result] Embodiment 2 will be described with reference to the drawing (4) when this apparatus is installed on a table and used. The rotating device (A) is 5 r. p. 1.5W small motor with m, mirror (B) 10 * 20mm, protrusion (5) slightly touches arm (6), static angle (a) is 55 degrees, laser light source (C) is lens It is 2mW.

This device was placed on a desk using the mounting seat (10) and the laser light was emitted from the laser light source (C) while rotating the rotating device (A).

As a result, the point-like light of the laser light swirled while drawing a gentle and complicated curve due to the slight contact between the arm (6) and the protrusion (5).
