Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to lighting equipment such as direct-mounted or recessed lights used for main lighting or local lighting in houses, stores, facilities, etc. In particular, it relates to the structure of a shade that covers a lamp.

(Prior Art) Conventionally, as shown in FIGS. 6 and 7, a reflector plate 3 in which a lamp socket 2 is provided is placed inside a fixture body 1 that is embedded in a mounting surface such as a ceiling surface and has an open bottom surface. A compact fluorescent lamp 4 is attached to the lamp socket 2 in a removable manner, and a shade 6 made of a semi-transparent material with a frame 5 made of an opaque material provided around the periphery is attached by a V-shaped spring (not shown) to the lamp socket 2. A lighting fixture with a shade is known which is attached to the main body 1 and has a structure in which the lower opening of the main body 1 is covered by the gently spherical shade 6. Note that 7 is a ballast for the fluorescent lamp 4. However, in such conventional lighting equipment with a shade, the shade 6, which diffuses and transmits the direct light from the fluorescent lamp 4, has a flat shape with little unevenness. There was a lack of synergy with the production. Further, although the only light related to illumination is the direct light from the lamp 4 that passes through the shade 6, it may be too bright depending on the interior of the room.

Further, as shown in FIGS. 8 and 9, a reflective plate 12 having a concave shape on the opening side of the lower surface is removably attached to the instrument main body 11 as described above, and the end edge of the reflective plate 12 is A chassis 14 provided with a lamp socket is attached to the appliance main body 11, a fluorescent lamp 15 is attached thereto, and a frame-shaped cover unit 18 consisting of a flat plate portion 16 and an inner circumferential wall 17 is attached to the bottom surface of the appliance main body 11. An indirect lighting fixture is also known which has a structure in which the fluorescent lamp 15 is covered so that it cannot be seen directly by the cover integral 18 made of an opaque material. Note that 19 is a stabilizer. According to this indirect lighting fixture, very soft light can be obtained and no shadows from the lamp 15 appear. However, in such conventional indirect lighting equipment, the light from the fluorescent lamp 15 is reflected by the reflecting plate 1.
Since the lighting was performed using the reflected light reflected by 2, it felt dark.

(Problems to be Solved by the Invention) As mentioned above, conventionally there have been lighting fixtures with shades that provide illumination using transmitted light, and indirect lighting fixtures that provide illumination using reflected light. In order to obtain the effects of both types of light, there was a problem in that both types of lighting equipment had to be used.

Furthermore, lighting fixtures with shades may be too bright, while indirect lighting fixtures may be too dark, making them difficult to adapt to increasingly diverse interiors. Further, in the conventional lighting fixture with a shade, the shade 6 is planar, so the appearance and design sense is poor.

The present invention aims to solve these problems, and it is possible to obtain the effects of both transmitted light and reflected light, to obtain a design effect, and to be compatible with a variety of interiors. The purpose is to provide lighting equipment that can

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a device body, a lamp provided in the device body, and a shade provided in an opening of the device body to cover the lamp. In the lighting fixture, the shade has a stepped surface portion at an intermediate portion of the opening of the fixture body, and a first main surface portion farther from the fixture body on one side of the stepped surface portion, and It has a second main surface portion closer to the device body on the other side, and the step surface portion and the first main surface portion are made of a translucent material, and the outer surface of the second main surface portion facing the step surface portion is is a reflective surface, and furthermore, the lamp is disposed at a position facing at least the stepped surface portion and the first main surface portion.

(Function) In the lighting equipment of the present invention, during lighting, direct light from the lamp provided on the equipment main body is directed to the stepped surface of the shade and the first main surface located on one side of this stepped surface and farther from the equipment main body. At the same time, for example, the light transmitted through the stepped surface portion and diffused is reflected by the reflective surface of the outer surface of the second main surface portion located on the other side of the stepped surface portion and closer to the instrument body, and is irradiated. Ru.

(Example) Hereinafter, the configuration of an example of the lighting fixture of the present invention will be described based on FIGS. 1 to 3.

Reference numeral 21 denotes an instrument main body, and the instrument main body 21 has a substantially rectangular planar shape and a box-like shape with an open bottom. Furthermore, a flange portion 23 is formed on the lower surface of the instrument body 21 at an edge portion around the opening portion 22 .

Further, on the bottom side of the instrument main body 21, a reflecting plate 26 is provided.
is removably and fixedly attached, and a lamp socket 27 is fixed to the surface of the reflecting plate 26 on the opening 22 side. A base 29 provided at one end of a substantially U-shaped compact fluorescent lamp 28 is detachably connected to the lamp socket 27. On the other hand, a ballast 31 for the fluorescent lamp 28 is fixed to the other side of the bottom inside the appliance main body 21, and this ballast 31 is electrically connected to the lamp socket 27. Further, a plurality of locking fittings 32 are fixed to a side surface of the instrument main body 21 at a position closer to the opening 22.

36 is a shade, and this shade 36 has a substantially rectangular planar shape and covers the opening 22 of the appliance main body 21 in which the fluorescent lamp 28 is incorporated. Note that a flange portion 37 is formed at the edge portion around the shade 36 . Further, 38 is a frame provided to cover the peripheral part of the shade 36 from the outside, and the flange part 37 of the shade 36 is engaged with the inner peripheral part of the frame 38.

Further, a plurality of V-shaped springs 39 are attached to the frame body 38 and are respectively detachably engaged with the locking fittings 32 of the instrument main body 21.

The shade 36 has a stepped surface part 41 in the center thereof, which is perpendicular to the plane of the surrounding edges and parallel to the two edges of the shade 36.

Further, in the shade 36, one side of the stepped surface portion 41 is a first main surface portion 42 that is convex outwardly farther from the instrument main body 21, and the other side of the stepped surface portion 41 The second main surface 43 is closer to the instrument main body 21 (and is concave toward the outside).The step surface 41 and the first main surface 42 have a cross section of approximately
It is composed of the same letter-shaped member, and this member is made of a semi-transparent material.

On the other hand, the second main surface portion 43 is made of a non-light-transmitting material, and the outer surface facing the step surface portion 41 is a reflective surface. One edge of the second main surface 43 is fixed to the edge of the stepped surface 41 on the instrument body 21 side. Further, a reinforcing frame 44 is installed between two opposing sides of the frame body 38 along an outer edge portion on the opposite side of the stepped surface portion 41 that is common to one edge portion of the first main surface portion 42. ing.

Next, the operation of the above embodiment will be explained.

At the time of assembly, first, the appliance main body 21 with the reflector 26, lamp socket 27, and ballast 31 assembled is embedded and fixed in a mounting surface such as a ceiling surface, and a power supply line is wired. In addition, when it is attached to a ceiling surface, the direction shown by the arrow in FIG. 1 is downward. The following explanation assumes that it is installed on the ceiling.

After the fluorescent lamp 28 is attached, the bottom surface of the appliance main body 21 is adjusted so that the stepped surface portion 41 and the first main surface portion 42 face the fluorescent lamp 28 and the ballast 31 is covered by the second main surface portion 43. A shade 36 is fixedly attached to the section. That is, with the flange portion 37 of the shade 36 resting on the frame 38, the V-shaped spring 39 on the frame 38 side is engaged with the locking fitting 32 on the instrument main body 21 side.

In this state, the shade 36 is positioned substantially parallel to the ceiling surface, and the stepped surface portion 41 of the shade 36 is vertical. Further, the first main surface portion 42 is located further away from the ceiling surface and lower, and the second main surface portion 43 is located higher.

When in use, the direct light from the fluorescent lamp 28 and the light irradiated from the fluorescent lamp 28 and reflected by the reflective plate 26 on the back side of the shade 36 are transmitted to the stepped surface portion 4 of the shade 36.
1 and the first principal surface portion 42 . At the same time, the fluorescent lamp 28 that has passed through the stepped surface portion 41 and diffused
The light is reflected by the reflective surface of the lower outer surface of the second main surface portion 43 and is irradiated.

In this way, according to the above configuration, the lighting effects of both the conventional shaded lighting equipment and the indirect lighting equipment can be obtained with one lighting equipment.

That is, since the stepped surface portion 41 and the first main surface portion 42 having translucent properties efficiently transmit light, sufficient brightness can be obtained, and at the same time, soft indirect light can be obtained from the second main surface portion 43.

In the above embodiment, as shown in FIG. 3, the shade 36, which has a square planar shape, is divided into two parts parallel to a certain side of the frame body 38, so that the main surface parts 42, 43 and the space between them are divided into two parts. However, as shown in FIG. 4, by dividing the shade 36, which has a square planar shape, into two in the diagonal direction, both main surfaces 42, 43 and the stepped surface 41 are formed. You may also form a . Alternatively, as shown in FIG. 5, the planar shape of the shade 36 may be made circular, and this circle may be divided into two semicircles to form both main surface portions 42, 43 and the stepped surface portion 41. good.

Further, in the above embodiment, the stepped surface portion 41 is made perpendicular to the plane on which the frame body 38 extends, but the present invention is not limited to this. However, if the step surface portion 41 is made perpendicular to the plane on which the frame body 38 extends, the amphibian surface portions 42 and 43 can be made larger. Further, in the above embodiment, the first main surface part 42 is inclined with respect to the plane on which the frame body 38 extends, but when the two are made parallel to each other and the first main surface part 42 is installed on a ceiling surface, the first main surface part 42 may be horizontal. You can do it like this.

However, if the first main surface section 42 is inclined with respect to the plane on which the frame body 38 extends, as shown in FIG. 1, the stepped surface section 41 can be made larger. Further, the second main surface 43 may also be made parallel to the plane on which the frame body 38 extends, but if it is made at an angle as shown in FIG. easy to receive.

The shade 36 having the stepped surface portion 41 provides a rich appearance due to its uneven appearance, and together with the ability to express both transmitted light and reflected light, the design effect can be enhanced. Of course, the degree of emphasis on the unevenness of the shade 36 can be freely set by changing the size of the stepped surface portion 41.

In addition, the brightness can be freely set by changing the step surface portion 41 and the area ratio between the first main surface portion 42 and the second main surface portion 43. In this way, lighting fixtures compatible with a variety of interiors can be provided.

Furthermore, even when a plurality of the above-mentioned lighting fixtures are used, the design can be improved due to the shape characteristics.

In addition, although the above-mentioned example explained a ceiling recessed light, the above-mentioned shade 36 can also be used for a ceiling direct-mounted light.

〔Effect of the invention〕

According to the present invention, the shade that covers the lamp has a stepped surface, and the first main surface and the stepped surface located on one side of the stepped surface and farther from the appliance body are translucent. At the same time, since the outer surface of the second main surface located on the other side of the step surface and closer to the fixture body is used as a reflective surface, and the lamp is opposed to the step surface and the first main surface, a single lighting fixture can provide shade. It is possible to obtain both the transmitted light that passes through the shade and the indirect reflected light, and the unevenness of the shade enriches the external design sense. It is possible to provide lighting equipment that can be used in various interiors.
