Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling, in which a ceiling plate is installed between predetermined ones of a plurality of adjacent bars for a ceiling frame which are arranged at intervals, while the other is indoors. The present invention relates to a lighting fixture for an office provided with a system ceiling on which lighting fixtures for lighting are installed.

[0002]

2. Description of the Related Art This type of office lighting requires auxiliary lighting for separately illuminating each of a plurality of desks in addition to the main lighting by a lighting equipment fixture arranged on the ceiling. In order to perform the auxiliary lighting, conventionally, a stand is placed on each desk or is attached via a holder.

[0003]

However, in the case of placing the stand on the desk among the above-mentioned conventional techniques, the stand for auxiliary lighting is located on the desk and a part of the upper surface of the desk is placed. Because it had its own, it was inconvenient to use the desk. Also, when the stand is attached to the desk via the latter holder, the space that occupies the desk is reduced, but since the holder and the stand project upward from the desk, the drafter on the desk hits them. After all, it was easy to hinder the use on the desk. In short, according to the prior art, it is inconvenient to use a desk because of auxiliary lighting. An object of the present invention is to enable auxiliary lighting without disturbing the use of the desk.

[0004]

A feature of the present invention is that auxiliary bars for illuminating a desk placed in an office are provided on the bars for the ceiling frames arranged at intervals among the above-mentioned system ceilings. The point is that the spotlight is mounted so that it can change its direction. Further, it is preferable that the spotlights are arranged between a bar for supporting the ceiling plate and a bar for supporting the lighting equipment adjacent to each other with a small space therebetween.

[0005]

In the system ceiling, the main lighting is performed by installing the lighting equipment between the bars.
The bar crosses or vertically crosses the ceiling together with the lighting equipment. Focusing on this point, the spotlights that illuminate the desk are mounted on the bar so that the direction of the spotlights can be changed, so even if the spotlights for auxiliary lighting are attached to the ceiling instead of the desk, the longitudinal direction of the spotlight bar By adjusting the mounting position and changing the orientation of the desk, it is possible to accurately illuminate the desk from a desired angle in accordance with the change of the desk layout. In particular, when a spotlight is placed between the bar for supporting the ceiling plate and the bar for supporting the lighting equipment, it is possible to make the spotlight intrude into the ceiling to make it inconspicuous. It rarely changes the feeling.

[0006]

As described above, according to the present invention, the characteristics of the system ceiling are effectively used, regardless of the desk layout.
Moreover, auxiliary lighting can be performed on the desk while maintaining the desk in a convenient state. In particular, according to claim 2, it can be carried out without impairing the design feeling of the ceiling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, an office ceiling has a plurality of ceiling frame bars 1 arranged at intervals and suspended and supported by an upper slab (not shown). It is configured to support the plate 2 and the lighting equipment. The bar 1 has an inverted T-shaped cross-section so as to mount and support the ceiling plate 2 and the lighting equipment 3, and the intervals are three types, large, medium and small. More specifically, a pair of adjacent bars with a large gap are arranged on both sides in the juxtaposition direction of a pair of bars adjacent with a middle gap with a small gap. The ceiling plate 2 is installed between the bars 1 adjacent to each other with a large gap, and the lighting fixture 3 includes the bars 1 adjacent to each other with a middle gap.
The bars 1 are installed between and adjacent to each other with a small space therebetween (hereinafter referred to as a slit). ] S is used for the installation space of the broadcasting speaker and the air outlet for air conditioning. The lighting equipment of an office having such a system ceiling is configured so that the lighting equipment fixtures 3 installed on the ceiling perform main lighting and the spotlight 5 performs auxiliary lighting for each of the desks 4. As shown in FIG. 2, the spotlight 5 includes the lighting fixture 3
It is arranged in one of the slits S located on both sides of and is attached to the bar 1 so that the orientation can be changed. In the other side of the slit S, as shown in FIG. 3, a remote controller 6 is provided in a one-to-one correspondence with each spotlight 5.
A control switch 7 for controlling the spotlight 5 by receiving the control light (infrared ray, etc.) emitted from is arranged and attached to the bar 1. The spotlight 5 is one in which a condensing type dichroic beam is attached to a socket 8 as a light bulb, and its mounting structure has a slit S as shown in (a) and (b) of FIGS. 2 and 4. A vertically oriented bracket 9 having a fixed seat 10 that can be abutted between the lower surfaces of the bars 1 that sandwich and oppose is provided, and the socket 8 of the spotlight 5 is vertically rocked around the horizontal axis X at the lower end of the bracket 9. The mounting flange 1 of the bar 1 that is movably mounted and faces the bracket 9 with the slit S interposed therebetween by swinging around the longitudinal axis Y of the bracket 9.
The mounting flange 1A can be freely changed into a detachable posture in which it can pass vertically between A and a fixed posture in which it cannot pass, and by swinging to a fixed posture while passing from above to the mounting flange 1A, the mounting flange 1A described above. The movable seat 11 made of an elastic material such as a leaf spring for sandwiching and fixing the movable seat 11 with the fixed seat 10 is attached. That is, the spotlight 5 is configured to be attached by an operation from below the ceiling, and by swinging the socket 8 around the horizontal axis X with respect to the bracket 9, the direction [irradiation direction] is changed to the upper and lower directions.
The direction is changed to the horizontal direction by swinging about the vertical axis Y with respect to the bar 1. Reference numeral 12 is a down transformer provided in a one-to-one correspondence with each spotlight 5.

[Other Embodiment] In the above embodiment, the control switch 7 is provided for each spotlight 5, but as shown in FIG. 5, one control switch 7 is provided for a plurality of spotlights 5. May be provided and implemented. In the above-described embodiment, the control switches 7 of the spotlights 5 are arranged in a distributed manner. However, as shown in FIG. 6, the switch parts 7A of the control switches 7 are collectively arranged, and the switch parts 7A are combined into one light receiving part 7B. It may be configured such that it is selectively turned on / off by receiving light. In the above-described embodiment, the down transformer 12 is provided for each spotlight 5, but as shown in FIGS. 7 and 8, one downtransformer 12 is provided for a plurality of spotlights 5. It may be provided and implemented. In FIG. 7, a plurality of spotlights 5 are connected to one control switch 7
It is configured to turn on and off collectively with
FIG. 8 shows a configuration in which each spotlight 5 is individually turned on / off by a corresponding control switch 7. As shown in FIG. 9, the spotlight 5 is provided with a down transformer 12, and the downtransformer 12 is used as a fixed seat 10 so that the bar 1 is vertically sandwiched between it and the mounting seat ridge 13. . In this case, the mounting seat is configured to change its direction to the lateral direction by swinging about the longitudinal axis Y of the down transformer 12 with respect to the spring 13. In the above-described embodiment, the spotlight 5 is directly attached to the bar 1, but as shown in FIG. 10, the spotlight 5 is attached to the plate 14 installed on the bar 1 so as to be located between the lighting fixtures 3. You may attach and implement.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
