Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reflector device, and relates to one that is capable of adjusting the light distribution of a reflector formed of a plurality of reflector members used in, for example, a horizon light.

A conventional reflector device of this kind is, for example,
As shown in Japanese Patent No. 10147, a structure is adopted in which connecting edge pieces bent outward are connected to the ends of a plurality of reflecting plate members with screws or the like. In this conventional structure, the light distribution is determined by the bending angle of the connecting edge piece.
In order to change the light distribution, it is necessary to use a different reflector member whose connecting edge piece has a different bending angle, which lacks versatility.

The present invention was made in view of the above-mentioned problems, and an object thereof is to provide a reflector device consisting of a plurality of reflector members that can selectively change light distribution and increase the versatility of the reflector member. This is what I did.

The structure of the reflector device of the present invention is composed of a plurality of reflector members, and a connecting edge piece bent toward the back side is formed at the connecting end of one of the reflector members, Furthermore, an approximately U-shaped connection portion is formed in which an opening for fitting this connection edge piece is formed inside the connecting end of the other reflecting plate member, and a joining edge piece for joining this connection edge piece is formed facing each other. has been established. The connecting edge piece of one of the reflecting plate members can be selectively coupled to one of the connecting edge pieces of the connecting portion of the other reflecting plate member.

The function of the reflector device of the present invention is that the connecting edge piece of one reflecting plate member is bent outward and the connecting edge piece is formed in a substantially U-shape at the connecting end of the other reflecting plate member. The light distribution can be changed by selectively coupling to opposing joining edges of the connecting portion.

Next, the configuration of an embodiment of the present invention will be explained with reference to the drawings.

Reference numeral 1 denotes a main body of a device such as a lower horizon light, which is formed in the shape of a box having an irradiation port 3 with a translucent cover 2 provided on the front side. Side reflectors 4 are arranged and fixed on both sides of the inside of the main body 1 so as to face each other.

Reference numeral 5 denotes a reflector device, which is disposed on the back side between the two side reflectors 4. This reflector device 5 is composed of a first reflector member 6 and a second reflector member 7 which are divided. Each of the reflection plate members 6 and 7 is formed by extrusion molding of an aluminum alloy, and is formed of a plate-like body having a thickness of about 2.5 mm and having an arcuate reflection curved surface. The reflection curved surfaces of the first reflection plate member 6 and the second reflection plate member 7 are different from each other. At the connecting end 8 of the first reflector member 6 and the second reflector member 7, a connecting edge piece 10 is formed which is bent at a substantially right angle toward the back side and has a screw hole 9. Further, a fixed edge piece 11 is formed at the other end of the first reflector member 6 and bent at a substantially right angle toward the back side.

Further, at the connecting end 12 of the second reflector member 7 with the first reflector member 6, there is a connecting portion 1 bent in a substantially U-shape that protrudes toward the back side and has an opening 24 inward.
3 is formed. This connecting portion 13 is formed by one connecting edge piece 14 bent at a substantially right angle from the connecting end portion 12.
, a connecting portion 15 bent at a substantially right angle from this joining edge piece 14 , and the other joining edge piece 16 bent at an acute angle from the end of this connecting portion 15 facing opposite to the one joining edge piece 14 . and this both joining edge pieces 14,1
6 has locking holes 18 and 19 through which the connecting screw 17 is inserted. Further, a fixed edge piece 20 is formed at the other end of the second reflector member 7 and bent at a substantially right angle toward the back side.

In addition, sockets 21 are provided opposite to each other on both sides of the main body 1, and these sockets 21 respectively protrude from through holes 22 of the reflection plates 4 on both sides, and lamps 23 are attached to both sockets 21. .

The reflection plate device 5 then inserts the connection edge piece 10 of the first reflection plate member 6 through the inner opening 24 of the connection part 13 of the second reflection plate member 7, and
The connecting screw 17 inserted through the insertion locking hole 19 of the connecting edge piece 10 is screwed and tightened into the threaded hole 9 of the connecting edge piece 10, and this connecting edge piece 10 is attached to the inside of the other connecting edge piece 16. Close to. In this state, since the other joining edge piece 16 is inclined with respect to the one joining edge piece 14, the distance between the outer ends of both reflecting plate members 6 and 7 becomes narrower, and the light distribution becomes narrower.

The reflector device 5 assembled in this way is arranged inside the main body 1, and the fixing edge pieces 11, 20 on the other end side of both the reflector members 6, 7 are attached to the mounting pieces 26, 27 inside the main body 1 by screws 28. Attach each at.

In this way, a lower horizon light as shown in FIGS. 1 and 3 is constructed.

Alternatively, as shown in FIG. 2, the reflector device 5 may be turned upside down and another reflector member 29 may be connected to the fixed edge piece 11 of the first reflector member 6 to form an upper horizontal light. can.

In addition, when changing the light distribution of the reflector device 5, the fourth
The first reflector member 6 was in contact with the other joining edge piece 16 of the second reflector member 7 as shown by the chain line in the figure.
By abutting the connecting edge piece 10 of the connecting edge piece 10 on one of the connecting edge pieces 14 and connecting it with the connecting screw 17 as shown by the solid line in FIG. 4, the light distribution can be expanded.
Light distribution can be adjusted by selecting 4 or 16.

Further, the second reflector member 7 is a common component, and the first reflector member 7 is a common component.
The light distribution can be changed by converting only the reflector member 6, or the light distribution can be changed by replacing the second reflector member 7 with the first reflector member 6 as a common component. .

Also, the first reflector member 6 and the second reflector member 7
The connection is not limited to screws, but can also be made by clips or welding.

In addition, although the above-mentioned embodiment explained the horizontal light, it is not limited to the horizontal light, and can be applied to various lighting equipment.

According to the present invention, the connecting edge piece of the first reflecting plate member can be selectively coupled to one of the opposing connecting edge pieces of the substantially U-shaped connecting portion of the second reflecting plate member. Therefore, the light distribution can be easily changed just by changing the joining edge piece, and the desired light distribution can also be obtained by using either the first or second reflector member as a common part and changing the other. This makes it possible to easily manage parts, facilitate manufacturing control, improve the versatility of the reflector member, and reduce the cost.Furthermore, the structure of the first reflector member can be simplified by only forming a connecting edge piece. Also, the first reflector member can be easily attached, and the ease of assembly is improved.
