JPH10334713A - Combination type luminaire - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a combination type luminaire in which ends of light sources installed in luminaries adjacent to each other are overlapped, the intensity difference among light sources is hardly effected, the angle formed by luminaries adjacent to each other is adjustable and each luminaire can be supported according to the installation space of the luminaire. SOLUTION: Multiple long luminaries, each being equipped with a socket each at both of its ends, are connected in series; a rotative fitting 13 having an engaging piece 14 oriented toward the longitudinal direction of one of the luminaire main bodies 11 adjacent to each other is retained on it only at the point of its rotation axis in a rotatable manner; on the upper wall of the longitudinal edge of the other of the luminaire main bodies 11 adjacent to each other, a position adjustment long slot 18 is formed; the engaging piece 14 is so formed to move back and forth along the position adjustment long slot; a connector-wire inserting hole 15 is formed on the side wall of the luminaire main body; thus the luminaires are structured to be combined with one another.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an articulated luminaire.

[0002]

2. Description of the Related Art Heretofore, a so-called architectural lighting system has been adopted in which lighting fixtures are incorporated into a ceiling or a wall of a building such as an office or a hotel to be integrated with the building. As a construction of the architectural lighting system, for example, as shown in FIG. 5, fluorescent lamps are arranged on the bottom surfaces of both ends of the lighting fixture main body 1, and the ends of the long tube-type fluorescent lamps 2 adjacent to the fluorescent lighting fixture overlap. They are arranged and arranged as if they meet each other.

[0003]

According to the above-described connected lighting apparatus, the ends of the adjacent long tube fluorescent lamps overlap each other, so that uniform brightness can be obtained as a whole. by the way,
The walls of the building are deformed, and depending on the mounting space of the lighting equipment, the angle of the adjacent fluorescent lighting equipment may need to be variable depending on the mounting space of the adjacent fluorescent lighting equipment. However, according to the conventional structure, the angle between adjacent long tube-type fluorescent lamps cannot be changed, and depending on the shape of the mounting location, the fluorescent lamp lighting fixture may not be able to be mounted, and a desired brightness may not be obtained. There are drawbacks that cannot be achieved.

[0004] The present invention has been made in view of the above points, and has a small difference in brightness between adjacent lighting fixtures.
It is another object of the present invention to provide a connection type lighting fixture that can be mounted in accordance with a mounting space for the lighting fixture.

[0005]

Means for Solving the Problems The present invention has the following constitution in order to solve the above problems. The invention described in claim 1 is
In a connection type lighting fixture in which a long lighting fixture main body having sockets arranged at both ends is connected, a turn piece having a hanging piece downwardly on a longitudinal end upper wall of one adjacent lighting fixture main body. The moving fitting is rotatably mounted on a shaft.
Further, a long groove for position adjustment is provided on the upper end wall in the longitudinal direction of the other luminaire main body, and the engaging piece is configured to move back and forth along the long groove for position adjustment. In addition, the connector passage hole is formed on the side wall of the lighting fixture main body, and the lighting fixture main body is sequentially connected.

According to a second aspect of the present invention, an adjacent luminaire main body is set at an arbitrary position of a position adjusting long groove of an upper end wall in a longitudinal direction of the luminaire main body according to the first aspect. It is configured to be able to do. And it is comprised so that the space | interval with which adjacent lighting fixtures overlap can be adjusted, and the angle of adjacent lighting fixtures can be adjusted.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIGS. In FIG. 1 to FIG. 4, reference numeral 11 denotes an elongated lighting fixture main body, for example, which is formed in a box shape with an open lower surface. Reference numerals 12 are sockets arranged at both ends of the lighting fixture main body 11, for example, fluorescent lamp sockets. Reference numeral 13 denotes a rotating bracket rotatably disposed on the upper end wall of the adjacent one of the lighting fixture main bodies in the longitudinal direction, and has a hooking piece 14 extending downward from the side wall of the lighting fixture main body. It is composed. Reference numeral 15 denotes a connector through-hole formed on a longitudinal side wall of the lighting fixture main body, and 16 denotes a connector disposed inside the lighting fixture main body, and leads from the connector through-hole 15 of an adjacent lighting fixture. It is configured to connect wire nectars. Reference numeral 17 denotes a scale for indicating the rotation angle of the rotation fitting.

Reference numeral 18 denotes a position adjusting long groove formed on the upper end wall of the other lighting fixture main body 11, which engages with the engaging piece 14 of the rotating fitting and moves back and forth to set the position at an arbitrary position. It is configured to be set. In addition, the engaging piece 14 of the turning fitting is moved to the outer end of the long groove for position adjustment, and by turning the turning fitting, it is possible to set an arbitrary angle with the adjacent lighting fixture body.

Next, a description will be given of an embodiment of the above-mentioned connected lighting apparatus. FIG. 4 shows an embodiment in which a plurality of luminaires are arranged in a straight line. A fluorescent lamp mounted on a socket is configured so that the ends overlap by about 10 cm to 20 cm. This embodiment is suitable for, for example, library ceiling lighting.

FIG. 2 shows an embodiment in which adjacent lighting fixtures are arranged at an angle, and the angle between the adjacent lighting fixtures can be adjusted within a range of 0 to 90 degrees. This embodiment is arranged at an angle of 90 degrees and is suitable for illumination of, for example, a rectangular ceiling. Further, as shown in FIG. 3, it may be configured to have an angle of about 45 degrees with an adjacent lighting fixture.

[0011]

According to the present invention described above, the difference in brightness between adjacent lighting fixtures is small, the lighting fixtures can be installed in accordance with the mounting space of the lighting fixtures, and the mounting angle of the adjacent lighting fixtures can be set at any angle. There is a special effect that can be set.
