Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting fixture that is installed on an indoor wall or ceiling of a building, and in particular, the light from a light source lamp fixedly installed on the wall or ceiling is crossed at a certain angle. By irradiating a set of several dichroic mirrors, a light ray pattern that is the same as the color light rays that pass through the mirror (and the reflected color light rays) is projected onto the wall or ceiling surface, for example, as a show light. - It was devised to provide a highly varied and symmetrical lighting effect that is particularly useful in the interior decoration of stores and other stores.

Hereinafter, the specific structure of the present invention will be described in detail based on the illustrated embodiment. In the first embodiment shown in FIGS. It is a plate-shaped or square plate-shaped base plate, and it can be directly attached to the wall surface (W) with bolts (not shown) inserted through a plurality of bolt insertion holes (11) arranged open around the periphery. It is set to be fixed. (12) is a through hole for a rotating shaft opened in the center of the base plate (A);
Reference numeral 13) denotes a plurality of support brackets welded to the back of the base plate (A), which have an abbreviated shape. is installed.

(16) is a motor built into the motor case (15), which is also installed with a plurality of screws (18) to the leg stand (17) which is backed and fixed to the base plate (A). The output rotating shaft (19) is led out to the surface side through the through hole (12) of the base plate (A). (20) is the motor case (
15), and it goes without saying that it is connected to a power source (not shown) via a wiring cord.

Further, (B) is a mirror holding frame, which includes a support frame portion (22) in which the bearing tube (21) is embedded and fixed, and the support support frame portion (22).
A pair of bar frame parts (2) are continuously and integrally protruded from the upright tip of the bar frame part (2) in a V-shaped bifurcated shape when viewed from the front as shown in Figure 1.
3), and when viewed from the side, the support frame part (
22) and each bar frame portion (23) have an abbreviated shape in which they are perpendicular to each other as shown in FIG. Moreover, the support frame part (22
) and both bar frame parts (23) are curved into a generally U-shaped cross section that communicates with each other as shown in Fig. 5, and a square plate-shaped dichroic mirror (24) is placed inside the groove. , are removably fitted as a set of two.

That is, the two right-angled sides of each mirror (24) are fitted into the support frame (22) and bar frame (23) of the mirror holding frame (B), and are fixed with screws (25). It is. Therefore, the flat plate surfaces of both mirrors (24) are arranged to be orthogonal to the flat plate surface of the base plate (A). (26) is a rubber backing fitted into the mutual gap between each mirror (24) and each bar frame (23).

Further, (27) is a holding plate that presses and fixes the set of two mirrors (24) to the support frame (22) simultaneously and in a branched state, and is similar to the support frame (22). It has a medium-sized, approximately U-shaped cross section. (2B) is a rubber backing fitted between the holding plate (27) and both mirrors (24), and (29) is a screw for fixing the holding plate (27). The bearing tube (21) protruding from the support frame portion (22) of the mirror holding frame (B) is fitted onto the output rotating shaft (19) of the motor (16), and is interconnected with the connecting screw (30). It is assembled to rotate as one unit.

In that case, in the first embodiment, as suggested from FIG. 1.5, a pair of bar frames (23
), the pair of mirrors (24) are held at an intersection angle (θ) of approximately 36 degrees, and the intersection angle (θ) is shown in the second embodiment in Fig. 6.7. For example, they can be set at about 90 degrees or other angles, and may be fitted in a 180 degree straight line arrangement.

Also, as shown in Figure 6.7, the mirror holding frame (
As for the overall form of B), a pair of bar frames (23) that are parallel to each other and have a difference in length are protruded from the base end and the tip of the support frame part (22), and both of the bar frame parts (
23) can be rigidly connected and integrated by the beam pieces (31) at the corner positions.

(32) is a screw that fixes the beam piece (31) to the support frame (22). Furthermore, although not shown, as long as a constant intersection angle (0) is maintained between adjacent mirrors (24), the mirrors (24) can be arranged as a set of two or more mirrors, for example, in a radial arrangement. It can also be said that it is possible to hold it fixedly to the mirror holding frame (B).

Each mirror (24) is made of flat glass, and dichroic processing is applied to the plate surface. In other words, by appropriately changing the thickness of the metal oxide layer coated on the plate surface, the light source lamp (3
3) When receiving light from a source, depending on the predetermined direction and angle of incidence, the light is transmitted, and depending on a different direction and angle of incidence, the light is reflected, and in the same direction of incidence. -Depending on the angle, they emit different colors.

In the illustrated embodiment, the set of two mirrors (24) are installed while maintaining an acute intersection angle (θ) of about 90 degrees, so for example, one of the mirrors (24)
) is also transmitted through the other mirror (24) or is reflected by the other mirror (24), and vice versa also occurs between the two mirrors (24). becomes. Furthermore, since both mirrors (24) are rotationally driven by the motor (16), the direction and angle of incidence of the light emitted from the lamp (33) automatically changes from moment to moment. As suggested by the results in FIG. 8, the above transmission and reflection effects weave a highly complex and polymorphic color ray pattern.

In any case, the light source lamp (33) is fixedly installed on the wall (W) or ceiling (C), and the light emitted from it is emitted from the base plate (A) (wall or wall surface) as shown in Figure 8. The support frame portion (22) of the mirror holding frame (B) stands up from its base plate (A) along a direction substantially parallel to the ceiling surface (which may also be referred to as the ceiling surface) (the intersection point or center of rotation of both mirrors). It will be irradiated towards the area).

At the beginning, the mirror holding frame (B) is moved by the motor (16).
Although the embodiment has been described in which the motor (16) is rotationally driven, for example, as shown in the third embodiment shown in FIG. ) on the base plate (A) in a non-rotatable fixed state in advance, and the light from the lamp (33) is directed onto the plate surface of the mirror (24) at any direction and angle of incidence. It is also possible to irradiate. Even with this configuration, a dichroic-processed mirror (24
), it is possible to obtain a colored light ray pattern woven by the above-mentioned reflection and transmission. Although the lighting equipment of the present invention has been described as being installed on an indoor wall surface (W), it can also be installed on a ceiling surface (C).
It goes without saying that it can also be used by attaching it to ).

As described above, the lighting fixture of the present invention includes a base plate (A) that is attached to an indoor wall surface (W) or a ceiling surface (C);
A mirror holding frame (B) is erected from the base plate (A); as a set of several frames that are perpendicular to the plate surface of the base plate (A) and maintain a constant intersection angle (θ). , a dichroic mirror (24) fitted into a mirror holding frame (B), and a base plate ( Along the direction substantially parallel to the plate surface of A), the mirror (24)
By pointing and irradiating the intersection of the mirror (2
4) Since the setting is such that the light ray pattern woven from the color light rays that pass through and the color light rays that are also reflected is projected onto the wall surface (W) or ceiling surface (C), for example, it can be used on a show window or When used in the interior decoration of various stores, it is possible to create a symmetrical composition of light that is extremely interesting and varied, and it is possible to obtain a unique, temporary lighting effect, and the necessary configuration is extremely simple.

Further, a motor (16) is fixedly held on the base plate (A), and the mirror holding frame CB) is rotationally driven by the motor (16).
The light source lamp (33)
), the light ray pattern woven from the colored rays that pass through the mirror (24) and the colored rays that also reflect is automatically changed from moment to moment on the walls (W) and ceiling surfaces. If you set it to project onto (C), you will be able to dynamically draw out an extremely diverse pattern of light beams, as if colorful searchlights are emanating from a rotating lighthouse in a spiral radial pattern, creating a fantastical effect. It is of great benefit in terms of being able to further improve oneself.
