Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluorescent lamp fixture and a reflector thereof, and more particularly to an embedded type equipped with a reflector which forms a high-intensity light source by effectively utilizing the light emitted from the fluorescent lamp tube. TECHNICAL FIELD The present invention relates to a fluorescent lamp and its reflector.

[0002]

2. Description of the Related Art Generally, a lighting device such as a fluorescent lamp (hereinafter referred to as a fluorescent lamp device) is installed close to or embedded in a ceiling or a wall surface of a room to be illuminated, except for a special case. The light emitted to the side opposite to the illuminated object is wasted. With a fixed wattage fluorescent light,
As a conventional technique for effectively using the emitted light to increase the effective luminance and increase the illuminance of an object to be illuminated, at least the lamp body mounting surface of the fluorescent lamp fixture is formed of a highly reflective material such as a stainless polished product. Also, there is known one in which a shade-shaped reflecting plate made of a material having a high reflectance is fixedly added.

An example of the existing fluorescent lamp fixture to which the above-mentioned umbrella-shaped reflector is attached to effectively utilize the radiated light of the fluorescent lamp is disclosed in Japanese Utility Model Publication No. Sho 64-10905. In the invention disclosed in the above publication, a reflecting flat plate made of a flexible material is curved along the axial direction of a straight tube fluorescent lamp, and a part of the outer circumference of the fluorescent lamp tube is extended to a holding portion that elastically holds. The curved portion is held by holding the side edge of the reflecting flat plate parallel to the fluorescent lamp axis by the engaging portion of the clip having engaging claws formed at the tips of the pair of arm portions.

Further, the embedded fluorescent lamp fixture is one in which an opening is provided in a mounting surface such as a ceiling plate, and the appliance main body is embedded in this opening so that the fluorescent lamp fixture does not largely project from the mounting surface. Is.

[0005]

In the above-mentioned conventional technique, the fluorescent lamp fixture itself is made of a stainless abrasive material,
The one to which the umbrella-shaped reflector is attached is difficult to process and the number of parts increases. In addition, in the case of attaching a reflector to an existing fluorescent light fixture, the shape and structure of the fluorescent light fixture, the positions of the mounting screws and sockets, or the distance between the fluorescent light fixture and the lamp body differ depending on the manufacturer. It is necessary to create a reflector mounting structure suitable for lighting fixtures.

Further, there is a problem that cleaning work is difficult when the reflecting plate is soiled due to adhesion of dust or smoke. And
This type of reflective equipment and reflector is expensive because it requires a manufacturing process such as mirror surface processing when the material is stainless steel and a protective film coating process after mirror surface processing by chemical polishing when it is aluminum. Moreover, it is extremely difficult to provide an optical flat surface, and even a slight decrease in flatness significantly deteriorates the reflection characteristics, resulting in a marked deterioration in appearance.

In the reflector disclosed in Japanese Utility Model Laid-Open No. 64-10905, the reflector made of a flexible material is curved at right angles to the axial direction of the straight fluorescent lamp tube, and the reflector is outside the fluorescent lamp. The clip is attached to the circumference to fix the side edge of the reflection plate by fixing the side edge of the reflection plate, but the curvature of the reflection plate is fixed and the side edge is dotted. Therefore, there is no guarantee that the curved surface will be kept uniform, and there will be a constant distortion in the curved surface at least at the above-mentioned fixed point, and the reflection will not be uniform.

If the reflecting plate is made of a material having a shape self-holding property such as a metal plate, the curvature can be held without using the locking claws, and the locking claws serve as a function of securing the position of the reflecting plate. However, since a reflector such as a metal plate has a large weight, it is necessary to separately provide some auxiliary supporting means in order to increase the strength of the clip and to avoid damage to the tubular body.

In order to avoid this, if the reflecting plate is made of a lightweight material, it becomes difficult to keep the side edge portions of the reflecting plate other than the locking claw portions in a straight state. If this side edge portion is not held straight, it causes irregular distortion on the reflecting surface, and the emitted light of the fluorescent lamp is not uniformly reflected, so that the function as a reflector is deteriorated. In addition, in most conventional embedded fluorescent lamps, in order to give the fluorescent lamp itself a light reflecting function, the main body is composed of a white-painted steel plate. Then, only about 10 to 15% of the light emitted to the device body side is reflected as effective light.

When the above-mentioned coating color is chromatic in order to provide a decorative effect, the reflection efficiency is further lowered, so that the present fluorescent lamp fixture main body is limited to almost white. In this way, the shape of the fluorescent lamp fixture and its light source has many decorative elements, and when viewed as a light source with an effective spread including the reflector having the above-mentioned irregular distortion, It was difficult to obtain a decorative effect by making the color look chromatic and improving the brightness.

The object of the present invention is to solve the above-mentioned problems in the prior art, to have uniform reflection characteristics, to be lightweight, easy to install, and to be easily attached and detached even when trouble, inspection, cleaning or repair is required. Another object of the present invention is to provide a built-in fluorescent lamp fixture having a reflective plate attached thereto and the reflective plate thereof.

[0012]

In order to achieve the above object, the present invention employs a heat resistant resin film capable of forming a uniform curved surface as a reflector main body in an embedded fluorescent lamp device having a conventional structure. It is characterized by facilitating the attachment and detachment of the reflector main body. That is, according to the present invention, the embedded fluorescent body including the frame-shaped portion 21, the connecting plate portion 22 and the component storage portion 23 is fixed to the inner edge portion of the opening 11 formed in the mounting surface 1 by the frame-shaped portion 21. An embedded fluorescent lamp fixture having a lamp body 2 and a fluorescent lamp tube 8 installed so as to be exposed from the embedded fluorescent lamp body 2 to the mounting surface 1 side. And a fluorescent plate 8 installed between the fluorescent tube 8 and the fluorescent tube 8 to effectively use the light emitted from the fluorescent tube 8.
The reflector is provided with a fluorescent lamp tube body 8 and an embedded fluorescent lamp fixture body 2
Is fixed to both end edges of the reflector plate body 6 forming a reflecting surface curved in a direction orthogonal to the longitudinal direction of the fluorescent lamp tube body 8 and the both ends of the reflector plate body 6 parallel to the longitudinal direction of the fluorescent lamp tube body 8. It is characterized by including the edge member 61 and a locking portion 7 for fixing and supporting the edge member 61 of the reflector main body 6 to the connecting plate portion of the embedded fluorescent lamp fixture main body 2.

The locking portion 7 is made of a permanent magnet fixed to the edge member 61 so as to be attracted to the connecting plate portion 22 of the embedded fluorescent lamp fixture body 2, and the permanent magnet is attracted and fixed to the connecting plate portion 22. By doing so, the reflecting plate body 6 is curved in a direction orthogonal to the longitudinal direction of the fluorescent lamp tube body 8 to form a reflecting surface. Further, the locking portion 7 is composed of a plurality of locking pieces 72 mounted in parallel with the fluorescent lamp tube body 8 in the vicinity of the connecting plate portion 22 of the embedded fluorescent lamp fixture body 2, and locks the edge member 61. By engaging with the side 72, the reflecting plate body 6 is curved in a direction orthogonal to the longitudinal direction of the fluorescent lamp tube body 8 to form a reflecting surface.

Furthermore, the engaging portion 7 is composed of a groove 73 formed integrally with the fluorescent lamp tube body 8 in parallel with the fluorescent lamp tube body 8 in the vicinity of the connecting plate portion 22 of the embedded fluorescent lamp fixture main body 2. 6
By engaging 1 with the groove 73, the reflecting plate body 6 is curved in a direction orthogonal to the longitudinal direction of the fluorescent lamp tube body 8 to form a reflecting surface. Then, the reflector is a colorless or colored heat-resistant transparent resin film substrate and a light-reflecting layer adhered to one surface of the transparent resin film substrate, and a protective layer coated on the light-reflecting layer. It is characterized by comprising a substantially rectangular reflector main body configured and an edge member fixed to two parallel edges of the reflector main body, and characterized in that a permanent magnet is fixed to the edge member. To do.

[0015]

[Function] A heat-resistant transparent resin film such as polyester or polycarbonate is used as a base material, and silver, aluminum, brass or the like is deposited on one surface thereof by a film forming means such as vacuum deposition,
A rod-shaped body made of metal such as aluminum or a hard resin is fixed as an edge material to two parallel edges of a substantially rectangular reflector main body having a planar restoring property formed by coating a protective layer thereon, and this edge material is interposed. It is attached to a frame-shaped portion for fixing the embedded fluorescent lamp fixture body to a mounting surface such as a ceiling plate or a connecting plate portion for connecting the frame-shaped portion and the embedded fluorescent lamp fixture body.

By setting the size of the reflector between the edge members to be larger than the size of the width of the embedded fluorescent lamp fixture body in the direction orthogonal to the mounting direction of the fluorescent lamp tube, the reflector is embedded. By attaching to a fluorescent lamp fixture, a uniform curved surface can be formed in a direction orthogonal to the longitudinal direction of the fluorescent lamp tube. The curved surface is held by the rigidity of the resin film forming the reflector main body and forms a distortion-free reflecting surface.

The reflection plate is attached by a structure in which the permanent magnet fixed to the edge member is attracted to the connecting plate portion connecting the embedded fluorescent lamp fixture body and the frame-shaped portion, or the fixing member fixed to the connecting plate portion. By attaching the stopper piece or the groove portion integrally formed on the connecting plate portion, the embedded fluorescent lamp fixture or the fluorescent lamp tube can be attached.
It is extremely easy to attach and detach the reflector when a failure, inspection, cleaning or repair is required.

By covering most of the area on the back surface of the fluorescent lamp with the reflector using this reflector, the light emitted from the fluorescent lamp tube can be effectively used to provide a large-area light-brightness light source. When the resin base material that constitutes the reflector main body is made chromatic, the decorative effect can be obtained without impairing the brightness.
