[Industrial applications]

 The present invention relates to a reflector for a fluorescent lamp, and particularly, it can be installed in a tube body of a straight tube fluorescent lamp to effectively use the emitted light of the fluorescent lamp and add color to the illumination light. The present invention relates to a high-intensity reflector for a straight tube fluorescent lamp.

[0002]

[Prior Art]

 Generally, lighting fixtures such as fluorescent lamps are placed close to the ceiling or wall surface of the room, which is the target of illumination, and the light emitted to the side opposite to the target to be illuminated is wasted except in special cases. It is something. One of the conventional technologies to increase the effective brightness of a fluorescent lamp with a fixed wattage by effectively utilizing the emitted light and increase the illuminance of the object to be illuminated is to polish at least the lamp mounting surface of the fluorescent lamp with stainless steel. It is known that a product is made of a highly reflective material such as a product, or that a shade-shaped reflector made of a material having a high reflectance is fixedly added.

It is known that the existing reflector for a fluorescent lamp is attached to the above-mentioned umbrella-shaped reflector to effectively utilize the radiated light of the fluorescent lamp, as disclosed in Japanese Utility Model Laid-Open No. 64-10905. .. The invention disclosed in this publication is such that a reflecting flat plate made of a flexible material is curved along the axial direction of a straight tube fluorescent lamp and extended to a holding portion that elastically holds a part of the outer circumference of the tube body of the fluorescent lamp. The above-mentioned engaging portion of the clip having the engaging claws formed at the tips of the pair of arms holds the side edge of the reflecting flat plate parallel to the fluorescent lamp tube axis to maintain the curved state. ..

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional technique, the fluorescent lamp fixture itself is made of stainless steel abrasive material or the umbrella-shaped reflector is attached, the processing is difficult 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 position 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 that is suitable for lighting fixtures.

Further, there is a problem that cleaning work is difficult when the reflection plate is soiled due to adhesion of dust or smoke. In addition, this type of reflective equipment and reflector requires a manufacturing process such as mirror-finishing when the material is stainless steel, and coating processing of a protective film after mirror-finishing by chemical polishing when the material is aluminum. It is expensive, and it is extremely difficult to obtain an optical flat surface, and even a slight decrease in flatness significantly deteriorates the reflection characteristics, and the appearance is significantly deteriorated.

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 tube fluorescent lamp, and the reflector is provided on the outer circumference of the tube body of the fluorescent lamp. The clip is attached so that the side edge of the reflector is fixed by fixing the side edge of the reflector. Since it is supported in a fixed shape, there is no guarantee that the curved surface will be kept uniform, and there will be a constant distortion on the curved surface at least at the above-mentioned fixed point, and the reflection will not be uniform.

If the reflecting plate is formed of a material having a shape self-holding property such as a metal plate, the bending can be held without using the locking claws, and the locking claws act 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 increase the strength of the clip and to provide some auxiliary supporting means separately in order to avoid damage to the pipe 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 is not held in a straight line, it causes irregular distortion on the reflection surface, and the emitted light of the fluorescent lamp is not uniformly reflected, which deteriorates the function as a reflection plate. The shape of the luminaire and its light source has many decorative elements, and when it is viewed as a light source that has an effective spread including the reflector with the above-mentioned irregular distortion, its appearance deteriorates significantly. ..

The size of the curve of the conventional reflection plate of this type is determined substantially at the time of manufacturing, and it is difficult to change the size of the curve after that to change the effective spread of the light source. Also, if a reflector is installed on the fluorescent tube, the radiated light from the fluorescent tube that comes into contact with this reflector will be wasted, and there will be a shadow on the mounting surface such as a fixture or ceiling that will be the shadow of the reflector. Occurs, which leads to a decrease in aesthetics from a decorative point of view.

Further, the radiated light of a general fluorescent lamp is a white light source, and the above-mentioned conventional reflector merely reflects the white light of the radiated light of this fluorescent lamp as the illuminating light to the illuminated object. . When the illumination light has a color, that is, when the illumination light is colored, it is necessary to replace the fluorescent light source, which is a light emission source, with a color fluorescent light. It was necessary to change to a fluorescent lamp that emits.

The object of the present invention is to solve the above-mentioned problems in the prior art, to have a uniform reflection characteristic, to be lightweight, easy to attach, and to be able to set the curvature of the reflection surface arbitrarily, and also to give an arbitrary color to the illumination light. Another object of the present invention is to provide a high-intensity reflector for a fluorescent lamp, to which can be added.

[0012]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a heat-resistant resin film formed by vapor-depositing a rectangular high-reflecting material having a plane restoring property, and a rod-shaped edge fixed uniformly along both longitudinal edges of the heat-resistant resin film. And a holding portion for holding the outer periphery of the straight fluorescent lamp tube, and extending from a part of the holding portion in two directions substantially orthogonal to the longitudinal direction of the straight fluorescent lamp tube. A supporting clip for supporting the downward hanging of both rod-shaped edge members of the reflecting plate by a fixing clip for supporting the central portion in the longitudinal direction in contact with a part of the outer surface in the longitudinal direction of the tube body of the straight tube fluorescent lamp. The heat-resistant resin flume is colored in the high-brightness reflective plate for a straight tube fluorescent lamp that reflects the radiated light of the straight tube fluorescent lamp toward the illuminated side by gently fixing and supporting it and effectively obtains a high-brightness light source. It is made of a transparent film.

Further, the present invention is characterized in that a light transmitting region is formed at the central portion in the longitudinal direction of the straight fluorescent lamp tube body.

[0014]

[Action]

 A high-intensity reflector is formed by using a colored transparent film as the heat-resistant resin film, and a substantially central portion along the longitudinal direction of the high-intensity reflector is brought into contact with a part of the tube body of the straight tube fluorescent lamp. By arranging the rod-shaped edge materials on opposite sides of the tubular body, the plane restoration of the resin film that constitutes the high-brightness reflection plate and the self-weight of the rod-shaped edge material fixed to both longitudinal edges of the resin film. Forms a uniformly curved reflecting surface such as a substantially parabolic surface centered on the tube axis of the tube body of the fluorescent lamp.

By supporting the rod-shaped edge member by the support piece formed in the clip that holds the outer periphery of the tube body of the straight tube fluorescent lamp at least at two positions, and gently fixing and supporting the rod-shaped edge member, A high-brightness light source that maintains its shape and has an arbitrary color with an effective uniform spread is obtained. Regarding the color of the illumination light, a desired color tone and density can be set by selecting the color of the transparent film.

The light transmission region formed substantially in the center along the longitudinal direction of the high-brightness reflection plate is such that the radiated light in the portion in contact with the straight tube fluorescent lamp is extracted to the back surface side of the high-brightness reflection plate. The dark shadow on the back side of the reflector due to the installation of the above-mentioned high-brightness reflector is eliminated.

The fluorescent lamp is an ordinary white lamp, and the white light emitted from this fluorescent lamp is reflected by the colored transparent film 1-1 of the high-brightness reflector 1 as shown by the arrow in the figure, and the object to be illuminated is illuminated. Radiated to the side. At this time, the reflected light R becomes colored light according to the color of the colored transparent film 1-1, and the illuminated object is illuminated with the colored light.

The colored illumination light can be arbitrarily selected by changing the color tone and density of the color of the transparent film 1-1. Actually, you can obtain arbitrary colored illumination light by preparing multiple types of high-brightness reflectors consisting of transparent films with different color tones and densities and selecting them and installing them in a fluorescent lamp. . FIG. 2 is a partially broken plan view showing an embodiment of the structure of the high-brightness reflector according to the present invention. As shown in FIG. 2A, a heat-resistant resin film to which a dye or pigment is added. A high reflection film 1-2 made of aluminum is vapor-deposited on a transparent film 1-1 made of, and an aluminum anti-oxidation film 1-3 is deposited on this.

It is preferable that the size L in the longitudinal direction is substantially the same as the length of the straight tube fluorescent lamp to be applied, and the width W is equal to the peripheral size of the fluorescent lamp, but the length L is the installation site. It is optional because it can be cut with. In addition, the width W may be a wider size or a narrower size when the emphasis is placed on the decorative effect. In addition, as shown in FIG. 2B, a transparent area (non-reflection) in which the reflecting material is absent at an arbitrary width is provided in the central portion in the longitudinal direction of the high-brightness reflecting plate 1 , that is, the portion in contact with the fluorescent lamp. By providing the area), it is possible to eliminate the shadow of the fluorescent lamp on the ceiling surface of the ceiling lamp caused by the installation of the high-brightness reflector.

FIG. 3 is a side view of essential parts for explaining an example of a straight tube fluorescent lamp device provided with a high-intensity reflector according to the present invention, in which 1 is a high-intensity reflector, 2 is a rod-shaped edge member, and 3 is A holding portion, 4 is a clip, 5 is a fluorescent lamp tube body, 6 is a base, 7 is a fluorescent lamp fixture, 8 is a socket, and 9 is a mounting surface (ceiling). In the figure, the fluorescent lamp device is installed by fixing its fixture 7 to the ceiling 9 and inserting the terminal set in the base 6 of the tube 5 into the socket 8.

The high-brightness reflection plate 1 is loosely fixed and supported by a support piece formed on a clip 4 that holds the rod-shaped edge material 2 fixed to both longitudinal ends of the high-luminance reflection plate 1 while holding the outer periphery of the tubular body 5. By doing so, the tubular body 5 is installed so as to surround the whole or part of the upper and side portions in the longitudinal direction in the state of being formed into a curved surface shape such as a parabolic surface. The high-reflectance material-coated heat-resistant resin film 11 that constitutes the high-brightness reflector 1 is a biaxially stretched polyester resin film (for example, a registered trademark "Lumilar" manufactured by Toray Industries, Inc.) to which a dye or a pigment is added, and aluminum is vapor-deposited. Use what you did.

The registered trademark “Lumirror” is a resin film having a melting point of 263 ° C., resistance to moisture, a small thermal expansion coefficient, and good thermal dimensional stability. Then, it itself has a plane restoring property, that is, elasticity that tends to return to a flat state, and the substantially center line in the longitudinal direction is brought into substantially line contact with the upper surface of the tubular body 5 , so that the rod-shaped ends adhered to both end edges. The longitudinal edge of the edge member 2 hangs downward due to its own weight, and as a result, a curved surface such as a substantially parabolic surface having an axis parallel to the axis of the tubular body 5 is formed.

FIG. 4 is a schematic view of the AA cross section of FIG. 3, in which the high-intensity reflector 1 is in contact with the central portion at the portion indicated by A on the upper surface of the tubular body 5 so that both longitudinal end edges thereof are It hangs on both sides of the tube and curves as shown by the solid line B. Clip 4 extends from a portion of the holding portion 3 and the holding portion 3 for self-supporting and holding the outer periphery of the tube 5 in a direction perpendicular to the axis of the tube 5, a plurality of pairs to the tube side Arm 40 having supporting pieces 41-41, 42-42, 43-43.

The illustrated state shows the case where the amount of curvature is regulated by the pair of support pieces 42-42. However, if the pair of support pieces 41-41 is used, the curve indicated by the dotted line C and the pair of support pieces are shown. 43-43 can be used to set the curve indicated by the alternate long and short dash line D. Further, although three pairs of support pieces are shown in the drawing, the present invention is not limited to this, and four or more pairs or only one pair may be provided. When only one set is provided, it is possible to prepare a plurality of clips in which the supporting pieces are formed at different positions to change the size of the curve.

In addition, when a plurality of pairs of support pieces are provided, the installation intervals may be appropriately changed, and not the corresponding pair of support pieces but the left and right sides in the drawing are supported asymmetrically. You can also do That is, by fixing the right side to the support piece 41 and the left side to the support piece 43, the direction of the reflected light can be directed to the lower right side. When applied to a lamp, the reflected light can be directed to a specific illuminated object.

The clip for fixing the high-brightness reflector 1 is formed of a resin material or a metal material such as aluminum, and the shape thereof is not limited to that shown in the drawing. Further, the high-brightness reflection plate 1 controls the escape by inserting and holding the enlarged portion formed on the tip ends of the rod-shaped edge members 2, 2 into a pair of support pieces formed on the arm 40 of the clip 4. It is supported in a loosely fixed state.

The drooping downward in the high-brightness reflective plate 1 is received in this clip, the entire high luminance reflector 1 is installed freely move a slight extent. With such an installation, the high-brightness reflector 1 is protected from deformation due to vibration and wind, and the set curved shape is maintained. The attachment and replacement of the high-brightness reflector 1 to the fluorescent lamp are extremely easy because only the elasticity of the clip 4 itself is used.

When changing the color tone or shade of the illumination light, it is only necessary to replace it with a high-brightness reflecting plate having a desired color tone, and at that time, by selecting the supporting pieces 41, 42, 43 of the clip, to a certain extent. It is also possible to set the shading of. FIG. 5 is a partial perspective view showing an embodiment of the present invention, in which an enlarged size of a reflector and a clip is shown to emphasize a main part.

As shown in the figure, since the high-brightness reflector 1 has a simple structure in which it is attached by the clip 4 at the end of the fluorescent lamp body 5 , the attaching work is extremely simple and long. In the case of a standard fluorescent lamp, if the high-brightness reflection plate 1 is likely to be loosened in the middle (the central portion is drooping), a clip may be added at an appropriate place. Since the high-brightness reflector is attached directly to the fluorescent lamp tube, sufficient care must be taken regarding its weight and heat-resistant temperature.

The high-brightness reflector in the above-described embodiment is applied to a 40-watt class, the weight of the film part is about 10 g, the weight of the rod-shaped edge material is about 125 g, and the weight of the clip is two. Approximately 5 g (in the case of a resin clip), a total of about 140 g, which is extremely light, and the load on the four terminals of the tube is minimal. The temperature of the surface of the tube of the fluorescent lamp is 60 to 70 ° C in the steady state, the melting point of the high-brightness reflective plate is 263 ° C as described above, and the clip is made of the Duracon resin or the flame-retardant polyester. By using resin, the temperature can be at least 120 ° C, and there is no concern about deformation, welding, burnout, etc. due to heat.

The material of the reflector is not limited to the above materials as long as it has high reflectivity, high heat resistance and plane restoring property. Furthermore, this high-brightness reflector can be used not only for expanding the effective light source area of the fluorescent lamp and for colorizing the light source, but also as an interior building material.
