Problems solved by technology

[0009] However, there is room for improvement in terms of light distribution control, cost, and the like in the lighting fixtures described in the above patent documents.
That is, in the reflector surrounding the lamp in the above-mentioned conventional lighting fixture, since the reflector is fixed along the circumferential direction by the lampshade and many rivets, the assembling and manufacturing process of the reflector is complicated, and it is difficult to set the adjustment according to the purpose of use. light conditions etc.
In addition, when the part of the reflector has a polygonal shape curved in the circumferential direction, there is a disadvantage that the uniformity of illuminance in the circumferential direction is inferior to that of a smooth curved reflector.
In order to save resources and reduce weight, it is desired to use a thinner reflector, but when it is made into a thin plate, it is difficult to maintain the predetermined shape of the reflector after light distribution control

Embodiment 1

[0047] Next, the reflector of Embodiment 1 will be described in more detail with reference to the drawings.

[0048] figure 1 is the front view of the reflector, figure 2 is the top view of the reflector (a), the front view (b), image 3 It is an explanatory diagram of the disassembled assembly of the reflector, Figure 4 It is a partially enlarged explanatory diagram showing the state of installation to the fixing plate, Figure 5 It is a plan view before assembling of the slope part.

[0049] Such as figure 1 As shown in the front view of the lighting fixture of Embodiment 1, the reflector 10 of the lighting fixture of Embodiment 1 is suspended from the ceiling of a building, etc., and is installed under the lamp holder H of the lighting fixture on which a lamp (not shown) is installed so as to surround the lamp. , including upper and lower three layers of truncated conical inclined parts 11, 12, 13, and the inclination angles α1, α2, α3 formed by each inclined part wi...

Embodiment 2

[0060] Such as Figure 7 As shown in (a) and (b), the reflector 20 of the lighting fixture of Example 2 differs from that of Example 1 in that the lower end of the upper inclined portion 21 protrudes so as to cover the upper end of the lower inclined portion 22 . The reflector is the same, but the difference is that, as Figure 7 As shown in (a), the light distribution control unit 25 is provided on the fixed plate 24 , and no light distribution control unit engaged with the fixed plate is provided on the peripheral ends of the reflective plates 21 a , 22 a forming the inclined portions 21 , 22 .

[0061] In this case, the end portions of the belt plates of the fixing plate that bend and protrude from the position extending from the joint line S of the vertically adjacent reflecting plates can be accommodated so as not to bend in the axial direction, so that the adjacent The end portion of the reflector where the inclined portion protrudes can maintain the same inclination an...

Abstract

Provided is a reflective shade of a lamp, wherein a light control operation can be easily performed by a reflective plate, to control the distribution of light; the illumination intensity of a lamp can be improved without increasing power consumption; and the structure is simplified, and the shape is satisfactorily maintained. The reflective shade is disposed around an illumination lamp, and has the shape of a cup, the inner surface of which is a mirror surface. The reflective shade also has two or more inclined peripheral portions, the inclination angles of which are different. Each inclined peripheral portion is formed by connecting one or more fan-shaped reflective plates in the circumferential direction, and is supported and affixed by affixing plates each formed by bending a band plate.

Description

technical field [0001] The present invention relates to a reflector suitable for illuminating the ground below, which is installed in a lighting fixture such as a mercury lamp installed on a ceiling or the like of a building. Background technique [0002] Conventionally, as reflectors used for lighting fixtures such as downlights installed on the ceiling of buildings, etc., reflectors made by spinning aluminum plates have been used, but the surface roughness during processing is serious, and the reflective surface cannot Finished into a mirror finish. Therefore, there has been proposed a reflector for a lighting fixture that surrounds and combines a plurality of divided reflectors that have been finished in advance into a mirror-like surface by aluminum vapor deposition or the like. [0003] For example, in Patent Document 1 (Japanese Unexamined Patent Publication No. 2008-91208 ), a lighting fixture is described. The lighting fixture includes a lamp holder for mounting a l...
