BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a condensing / reflecting device for a fluorescent lamp which is attached to a linear fluorescent lamp to improve the illumination effect.

[0002]

2. Description of the Related Art A typical example of a lighting fixture using a fluorescent lamp used for lighting in general offices, shops, supermarkets, etc. is shown in FIG. 12 or FIG. That is, in the structure shown in FIG. 12, two linear fluorescent lamps c are held along a reflecting surface a in a fixture b having a V-shaped reflecting surface a formed by applying white coating on the surface. As shown in FIG. 13, the structure shown in FIG. 13 is a linear fluorescent light on the fixture e having a curved (usually referred to as inverted Fuji) reflective surface d formed by applying white paint to the inner surface. One or two lights c (one in the figure)
It is configured to be held. In addition, f shows a ceiling.

[0003]

However, neither in the case of the lighting equipment shown in FIG. 12 nor in the case of the lighting equipment shown in FIG. 13, the reflection effect is not emphasized, and the reflection surface is painted white. Therefore, the effect of reflecting the illumination light is low, and in particular, in the case of the luminaire shown in FIG. 12, since the illumination light is hardly collected from the orientation of the reflecting surface a and is diffused, Although it has the advantage of creating a soft atmosphere in the entire room, it cannot increase the illuminance,
On the other hand, in the case of the luminaire shown in FIG. 13, although the converging property is obtained from the shape of the reflecting surface d, there is a problem that the ceiling surface f becomes dark because the reflecting surface d blocks upward light rays. .. In any case, in the case of the lighting fixtures shown in FIGS. 12 and 13, it was not possible to efficiently amplify the amount of light emitted from the fluorescent lamp c and significantly increase the illuminance.

Therefore, the present invention is for a fluorescent lamp which can be easily attached to a fluorescent lamp and which can enhance the reflection effect so as to amplify the light emission amount of the fluorescent lamp to remarkably enhance the illuminance and contribute to energy saving. An object of the present invention is to provide a light collecting and reflecting device.

More specifically, the reflection plate 2 is a heat-resistant polyester film having a long and narrow rectangular shape having a required width wider than the diameter of the fluorescent lamp 1 and a length corresponding to the length of the fluorescent lamp 1. On the lower surface of the substrate 5 made of, for example, a mirror surface 6 as a reflecting surface is formed by aluminum vacuum vapor deposition processing, and at the central portion in the width direction of the substrate 5, a transparent portion 5a is provided so as to reach the entire length in the longitudinal direction. Reinforcing members having a U-shaped cross section are attached to both width ends of the substrate 5 so as to reinforce the width ends, respectively, along the entire length in the longitudinal direction.
As shown in an enlarged view in FIG. 3, ring-shaped magnets 8 are flush-embedded and fixed so as to form a part of the connecting portion 4 on at least the lower surface sides of the respective reinforcing members 7 in the longitudinal direction, and the stainless steel is used. The fixed pin-shaped stopper 9 made of a non-magnetic material such as brass or brass and having a spherical portion 9a formed at the lower end is used for the magnet 8
It is configured to be attached to the reinforcing member 7 through the center hole and the substrate 5.

On the other hand, the reflector holder 3 is made of a spring material made of a magnetic material having elasticity as a whole, and is a little over half of the outer peripheral length of the fluorescent lamp 1 so that the fluorescent lamp 1 can be elastically fitted from below. Has an arc-shaped fitting portion 10 having an inner circumferential length of, and arms 11 are respectively symmetrically projected to the outer side of the fitting portion 10 so as to correspond to the width end of the reflection plate 2, and An adsorption piece 1 for adsorbing to the magnet 8 of the reflection plate 2 so as to form a part of the coupling portion 4 at the tip of each arm 11.
1a is integrally formed by bending, and further attached to the suction piece 11a,
As shown in FIG. 4, the stopper hole 9 of the magnet 8 on the side of the reflection plate 2 is inserted, and the elastic restoring force of the rear arm 11 prevents the ball portion 9a of the stopper from retaining and holding the key hole. 12 is provided. The arm 11 is adapted to correspond to the width end of the reflection plate 2 by bending the tip toward the reflection plate 2 side as shown in FIG.

When the fluorescent light condensing / reflecting device of the present invention having the above-described structure is attached to the fluorescent lamp 1, first, as shown in FIGS. 1 and 2, the pair of reflecting plate holders 3 are attached in the longitudinal direction of the fluorescent lamp 1. Positioned at both ends, the fitting portions 10 are elastically fitted directly to the outer peripheral portions of the fluorescent lamp 1 from below. Next, the reflection plate 2 is arranged on the upper side of the fluorescent lamp 1, and the transparent portion 5a at the center of the substrate 5 is brought into contact with the upper surface of the fluorescent lamp 1. After that,
Each end of the reinforcing member 7 on the reflector 2 side is joined to the tip of the arm 11 of the reflector holder 3 by the joining portion 4. In this case, the magnet 8 fixed to the end portion on the lower surface side of the reinforcing member 7 is provided with the attracting piece 11a formed by bending the end portion of the arm 11 by slightly bending the arm 11 toward the reflecting plate 2 side. At the same time, the magnet 8 on the side of the reflection plate 2 is attracted to the magnet 8.
A fixing pin-shaped stopper 9 protruding from the central hole portion of the magnet 8 is inserted into the locking hole 12 formed in 1a. When the stopper 9 is inserted into the locking hole 12, an elastic restoring force acts on the arm 11 in the direction of arrow Z in FIG. 1, so that the suction piece 11a is prevented from coming off from the stopper 9 by the ball portion 9a of the stopper. At the same time as being held, a force pulling the substrate 5 in the direction of the arrow Y acts on the reflection plate 2, thereby stabilizing the reflection plate 2 in a state in which tension is applied on the fluorescent lamp 1. Can be made

In this way, when the fluorescent lamp 1 is used with the reflecting plate 2 attached to the fluorescent lamp 1, the illumination light emitted from the fluorescent lamp 1 is a mirror surface 6 formed on the lower surface of the substrate 5 of the reflecting plate 2. The fluorescent lamp 1 collects the light and reflects it downward.
The illuminance can be remarkably increased by efficiently using the light emission amount of, and as a result, energy saving can be achieved. Further, in the reflection plate 2, since the central portion in the width direction of the substrate 5 located on the upper surface of the fluorescent lamp 1 is the transparent portion 5a, a part of the illumination light emitted from the fluorescent lamp 1 is transparent. Since the light passes through 5a and is also irradiated toward the ceiling, the discomfort that the ceiling becomes dark can be removed, and the illuminance of the entire room can be increased and a soft atmosphere can be created.

As shown in FIG. 5, the inventor of the present invention attaches the fluorescent-light condensing / reflecting device of the present invention to each fluorescent lamp 1 of a general two-lamp type lighting fixture, and does not attach the device of the present invention. The illuminance was compared with that of the case and actually measured. In addition, in FIG.

In the above-mentioned actual measurement, a general office was used as an experimental place, two 40W fluorescent lamps 1 were used, the mounting interval A of each fluorescent lamp 1 was 12 cm, and no other lighting fixtures were used. went. As a result, at a point (a) where the distance B from the floor 13 was 70 cm directly below both fluorescent lamps 1, it was 328 lux when the reflection device was not installed, but when the device of the present invention was installed, it was 454 lux. It was Lux. Therefore, 454 ÷ 328 = 1.384, and the illuminance increase rate of 38.4% was confirmed. By the way, at the point (b) where the horizontal distance C is 50 cm from the point (b),
When the device of the present invention is attached, an illuminance increase rate of 22.8% is obtained, which shows that the entire room is bright.

Next, FIG. 6 shows another embodiment of the connecting portion 4, in which a stopper 9 having a spherical portion 9a at its tip serves as a stopper for preventing the magnet 8 and the attracting piece 11a from being displaced at the attracting portion. Instead, a stopper 7a for locking the bent end of the suction piece 11a is provided on the outer end of the reinforcing member 7 that reinforces the width end of the substrate 5.

In the case of the embodiment shown in FIG. 6, the arm 11
At the same time, the attraction piece 11a formed by bending the tip of the
Since a can be locked to the stopper 7a, it is not necessary to insert the fixing pin-shaped stopper 9 into the locking hole 12 of the suction piece 11a as in the above-described embodiment, and the reflector 2 can be easily operated. Since it can be set and the stopper 9 and the locking hole 12 can be eliminated, it is advantageous in terms of processing.

FIG. 7 shows a modification of the embodiment shown in FIGS. 1 to 4 and the embodiment shown in FIG. 6. In the case of the embodiment shown in FIGS. 1 to 4 and the embodiment shown in FIG. Although the stoppers 9 and 7a are provided in consideration of the elastic restoring force of the arm 11, the magnet 8 has a sufficient attracting force to resist the elastic restoring force, or the arm 11 In the case where the curved shape is preliminarily curved and a strong elastic restoring force does not act, the stoppers 9 and 7a are unnecessary, and the reflection plate 2 is fixed to the reflection plate holder 3 only by the attraction force of the magnet 8 and the attraction piece 11a. It shows the case where it can be held.

According to the modification of FIG. 7, the stopper 9
Alternatively, 7a is unnecessary, which is more advantageous in terms of processing.

FIG. 8 shows still another embodiment of the present invention. The reflector holder 3 is made of, for example, heat resistant reinforced plastic with a width of 4 to 8 mm, and the magnet 8 is attached to the tip of the arm 11. On the other hand, a magnetic attraction piece 11a is attached to the lower surface of the reinforcing member 7 on the reflection plate 2 side, and the stopper 7 is attached to the reinforcing member 7 in the same manner as shown in FIG.
a is provided.

Also in the embodiment of FIG. 8, the same operational effect as in the embodiment of FIG. 6 can be obtained. In the embodiment shown in FIG. 8, the stopper 7a may be eliminated as in the embodiment shown in FIG. Further, when the reinforcing member 7 is made of a magnetic material, the suction piece 11a can be omitted.

Further, FIG. 9 shows another embodiment of the present invention, in which the reinforcing member 7 on the reflecting plate 2 side is made of a magnetic material, while
The arm 11 of the reflector holder 3 is made of a non-magnetic material as in the embodiment shown in FIG. 8 and is formed in a thin plate shape, and the inner surface of the tip of the arm 11 corresponds to the outer end surface of the reinforcing member 7. A magnet 8 is attached to the connecting part 4 and a positioning part 11b is formed at the tip of the arm 11 so as to be bent in an L shape toward the reflecting plate 2 side.

In the case of the embodiment of FIG. 9, the reflection plate 2 can be held by the reflection plate holder 3 by attracting the magnet 8 on the inner side surface of the distal end portion of the arm 11 to the outer end surface of the reinforcing member 7, At this time, the magnet 8 and the reinforcing member 7 can be easily positioned by the L-shaped positioning portion 11b formed at the tip of the arm 11. In addition,
In FIG. 9, when the arm 11 is made of a magnetic material and the reinforcing member 7 is made of a non-magnetic material, the magnet 8 may be attached to the reinforcing member 7 side.

FIGS. 10 and 11 show still another embodiment of the present invention. Like the embodiment shown in FIGS. 8 and 9, the reflector holder 3 is made of a non-magnetic material and the connecting portion 4 is a magnet. The pin insertion method is adopted instead of the suction method using 8 and the suction piece 11a. That is, a fixing pin 13 having a spherical portion 13a at the head is projected from the tip of the arm 11 of the reflector holder 3 made of heat-resistant reinforced plastic, while on the other hand, on the reflector 2 side, at four corners, as shown in FIG. 4, a locking hole 14 similar to the locking hole 12 is provided in the opposite direction to that of FIG. 4 so as to penetrate the reinforcing member 7 and the substrate 5, and the fixing pin 13 is formed in a state where the arm 11 is curved.
The fixing pin 13 is retained and retained in the locking hole 14 by the elastic restoring force of the arm 11 by inserting the locking pin 14 into the locking hole 14.

In the case of the embodiment shown in FIGS. 10 and 11, the elastic pin of the arm 11 causes the fixing pin 13 to engage the locking hole 1.
Since it is securely held by No. 4, it can be coupled with one touch, and the magnet 8 in each of the above embodiments can be eliminated.

In the above embodiment, the case where the transparent portion 5a is provided in the widthwise central portion of the substrate 5 which constitutes the reflecting plate 2 is shown, but the same applies to a reflecting plate without the transparent portion 5a, Further, the mirror surface 6 formed as the reflecting surface on the substrate 5 may be formed by means other than aluminum vacuum vapor deposition. Further, in the embodiment shown in FIGS. 1 to 4 and FIGS. Although the case where it is made of a magnetic material has been described above, it is needless to say that only the adsorption piece 11a may be made of a magnetic material, and various changes may be made without departing from the scope of the present invention.
