Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to lighting devices such as store lighting and display lighting.
[0002]
[Prior art]
In general, as lighting in a store such as a department store, a spot that is produced by intensively illuminating general lighting that uniformly brightens the entire store as shown in FIG. 7 and a display such as a product as shown in FIG. Two types of lighting are used properly.
[0003]
Conventionally, when lighting fixtures need to be changed due to changes in sales floors, etc., spot lighting needs to be changed, expanded, or removed. In each case, electrical installation work and ceiling finishing material cut reinforcement and processing work are required. Had gone.
[0004]
[Problems to be solved by the invention]
Therefore, the above-mentioned conventional electrical construction work becomes full-fledged, and construction request work such as incision reinforcement and processing of finishing materials also occurs, which not only increases the construction cost but also impairs the aesthetics of the ceiling finish. There was a problem such as fear.
[0005]
The present invention has been made to solve the above-described conventional problems, and its purpose is to produce lighting quickly and inexpensively without requiring full-scale electrical construction work or ceiling finishing material processing work. An object of the present invention is to provide an illumination device capable of changing the method.
[0006]
[Means for Solving the Problems]
The lighting device of the present invention is abbreviated as a terminal block for selectively supplying one or a plurality of basic lighting units and either a basic lighting louver or a composite lighting louver and supplying power to the basic lighting unit. And having two openings that are opened separately on both sides of the terminal block, and a mounting frame that detachably attaches both ends of the basic lighting unit to the openings, When a basic lighting unit is attached to each of the openings, the basic lighting louver is selected, and when the basic lighting unit is attached to any of the openings, the combined lighting louver is selected. It is attached . Further, the composite illumination louver is characterized in that the downlight apparatus can be directly attached and removed or an opening for attachment is opened.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. 1 and 2, reference numeral 1 denotes a basic lighting unit, which is a lighting device that illuminates a lighting range generally and uniformly, for example, a 36 W or 55 W compact or straight tube fluorescent tube (not shown). I have.
[0008]
Reference numeral 2 denotes an attachment frame surrounded by a frame plate 2a, and has an opening 2b at the top where two (two in this embodiment) basic illumination units 1 can be attached. A terminal block 2c for supplying power to the basic illumination unit 1 is provided between the openings 2b.
[0009]
In this embodiment, as shown in FIG. 3A, the two openings 2b are separately provided on both sides of the terminal block 2c. However, as shown in FIG. 2b may be opened continuously. The inner surface of the frame plate 2a has a function of reflecting illumination light. The lower peripheral edge 2d of the mounting frame 2 is set in the cut opening of the ceiling finishing material.
[0010]
Reference numeral 3 denotes a basic illumination louver that regulates or reflects the direction of illumination light from the light source provided in the basic illumination unit 1 so that the entire illumination range can be illuminated uniformly.
[0011]
When attaching each of the above-mentioned appliances to the ceiling, first, as shown in FIG. 1, a basic illumination louver 3 is set in the attachment frame 2. Subsequently, as shown in FIG. 2, the basic lighting unit 1 is fitted into the opening 2b of the mounting frame 2 and is mounted in the mounting hole 2e with screws 1a or the like. As described above, the mounting frame 2 assembled with the basic illumination louver 3 and the basic illumination unit 1 is suspended from a ceiling slab such as a store building via a suspension bolt (not shown). The basic illumination louver 3 may be attached to the attachment frame 2 after the attachment frame 2 is suspended from the ceiling slab.
[0012]
Next, in order to change the general illumination by the basic illumination unit 1 to the combined illumination with the spot illumination, first, the basic illumination louver 3 is removed from the mounting frame 2 and then a plurality (two) of basic illuminations. Of the unit 1, the unnecessary basic lighting unit 1 is removed from the mounting frame 2. Subsequently, as shown in FIG. 4, the composite illumination louver 4 is set on the mounting frame 2. The composite illumination louver 4 is formed with an attachment opening 4a for attaching a spotlight downlight fixture 5 to which the downlight fixture 5 is attached in advance or later.
[0013]
In the embodiment shown in FIG. 4, the downlight fixture 5 is attached to the attachment opening 4 a of the composite illumination louver 4. However, as shown in FIG. 5, the opening 4 a is provided in the composite illumination louver 4. Alternatively, the downlight fixture 5 may be directly attached. In addition, as shown in FIG. 6, there is a method of attaching a lighting duct 6 to which the downlight fixture can be directly attached or attached to the composite illumination louver 4.
[0014]
Note that it is possible to provide only spot illumination by removing all the basic illumination units 1 from the mounting frame 2 and replacing the louvers with spotlight louvers.
[0015]
【The invention's effect】
1) Lighting production methods can be changed quickly and inexpensively without the need for full-scale electrical installation work or ceiling finishing material processing.
2) Lighting can be changed without impairing the aesthetics of the ceiling finish.
