Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a louvered fluorescent lamp fixture.

[Background of the invention]

As shown in the external view in Figure 5 and the cross-sectional view in Figure 6, glare-cut fluorescent lamps with louvers usually have a V-shaped cross-section that covers the ballast 1, etc. and is placed parallel to the fluorescent lamp. A louver consisting of a reflecting plate 2 and a plurality of baffle plates 3 perpendicular to the reflecting plate 2 is attached to cover the bottom of the fluorescent lamp. A plurality of slits 4 are provided perpendicularly to the V-shaped bent portion of 2, and a plurality of buffle plates 3 shown in FIG.
As shown in the figure, a round bar 6 or the like is sequentially inserted into the hole 5 of the inserted buttful plate 3 from inside the end of the reflector plate 2, and each buffle plate 3 is locked to the reflector plate 2. was. However, when assembling the louver with the above structure, the round rods 6 and the like are sequentially inserted through the plurality of buttress plates 3 from the ends, which is difficult to work with and requires a large number of man-hours, and also requires locking tools such as the round rods 6. There is a drawback that the manufacturing cost is high, and furthermore, after assembling the louver,
Some wobbling occurred between the buff-full plate 3 and the reflecting plate 2.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to obtain a louver-equipped fluorescent lamp fixture that does not require a locking tool or the like during assembly and allows a bump-full plate to be attached to a reflector plate with good workability.

[Summary of the invention]

In order to achieve the above object, the louvered fluorescent lamp apparatus according to the present invention includes a reflector plate having a V-shaped cross section arranged parallel to the fluorescent lamp, and a plurality of buttful plates perpendicular to the reflector plate. In the fluorescent lamp fixture with a louver, the louver is installed under the fluorescent lamp, and the louver has a plurality of slits on each bent surface in a direction perpendicular to the V-shaped bent portion of the reflector. By inserting and locking a plurality of buff-full plates having notches on the upper or lower sides into the slits, the upper or lower ends of the slits are pressed into contact with the notches at the upper or lower part of the buff-full plates. be.

[Embodiments of the invention]

Embodiments of the present invention will be described with reference to the drawings. 1st
The figure is an exploded perspective view of a louver in an embodiment of the louvered fluorescent lamp according to the present invention, FIG. 2 is a cross-sectional view of the louver when the buttful plate is inserted, and FIG. 3 is a sectional view of the louver after the buttful plate is inserted. FIG. 4 is a cross-sectional view showing a portion of the louver, and FIG. 4 is a cross-sectional view showing a portion of another embodiment of the louver. FIG. 3 is a diagram showing a state in which a buff-full plate is locked to two reflecting plates. In FIG. 1, a reflecting plate 2 having a V-shaped cross section and arranged parallel to a fluorescent lamp (not shown) has a plurality of pairs of slits 7 on each bent surface in a direction perpendicular to the V-shaped bent portion. Set up, Batsuful board 3
has a slight notch 8 at the center of its lower side.
The length of the slit 7 projected in the horizontal direction is approximately equal to the distance from the bottom of the notch 8 of the buff-full plate 3 to the opposite side, and the width of the notch 8 is the lower end of the opposite slit 7 of the reflecting plate 2. It is set equal to the distance between the outsides. As shown in Fig. 6, the reflector plate 2 is provided to cover the ballast 1 etc. attached to the fluorescent lamp fixture body, so it is generally bent into a V-shape at an angle of 50° or more. ing. Therefore, the slits 7 provided on the bent surfaces of the reflecting plate 2 are bent so that the bent surfaces of the reflecting plate 2 are brought together, so that the length of the slits 7 projected in the horizontal direction can be adjusted. It is possible to increase the
By the above-mentioned deformation within the limits of elasticity, a length can be obtained that allows sufficient insertion of the buff-full plate 3. That is, as shown in FIG. 2, the double-folded surfaces of the reflecting plate 2 are bent inward, and the length B of the slit 7 projected in the horizontal direction is made larger than the height A of the buffed plate 3 to form the buffed plate 3. Insert
When the notch 8 reaches the bent part of the reflecting plate 2, if the deflection of the reflecting plate 2 is returned to its original state, the notch 8 engages with the lower ends of both slits 7, and as shown in FIG. is attached to the reflector plate 2. In order to properly fix the baffle plate 3, the length D of the slit 7 projected in the horizontal direction on the reflector 2 in a normal state must be
However, it is necessary that the distance C from the bottom of the notch 8 of the flat plate 3 to the opposite side is equal to the distance C, and if the depth of the notch 8 is deep, the flat plate 3 may wobble when installed. be. Normally, the notch 8 with a depth of 1 to 2 mm can sufficiently fix the baffle plate 3 to the reflector plate 2.

FIG. 4a shows another embodiment in which a notch 8' of the buttful plate 3' is provided on the upper side of the buttful plate 3'.
In this case, if the width of the notch 8' is made equal to the distance between the outer upper ends of the opposing slits of the reflecting plate 2, a louver can be constructed in the same manner as in the above embodiment. Figures 4b and 4c show a wide area of the reflector plate 3 by sequentially inserting a buff-full plate 3'' or 3'' provided with a plurality of notches 8' or 8 into each slit of a plurality of parallel reflecting plates 2. This is a cross-sectional view showing a part when a louver is constructed, and as a large fluorescent lamp fixture for multiple lights is installed with a wide-area louver in which a large number of such reflecting plates 2 are connected, the louver assembly described above is The number of man-hours is further reduced, and an inexpensive fluorescent lamp fixture with a louver can be manufactured.

〔Effect of the invention〕

As described above, the louvered fluorescent lamp apparatus according to the present invention has a louver that includes a reflecting plate having a V-shaped cross section arranged parallel to the fluorescent lamp and a plurality of buttful plates orthogonal to the reflecting plate. In the fluorescent lamp apparatus with a louver installed below the fluorescent lamp, the louver is provided with a plurality of pairs of slits on each bent surface in a direction perpendicular to the V-shaped bent portion of the reflector, and the upper side or By inserting and locking a plurality of buff-full plates having notches on the lower sides into the slits, there is no need for a locking tool to attach the buff-full plates to the reflector, and the bent portion of the reflector can be bent to create a buff-full. Just by inserting the plate, the notch of the buttful plate and the slit end of the reflector plate will lock together and there will be no wobbling, so the number of man-hours required for assembling the louver is extremely small, making it an inexpensive fluorescent lamp with a louver. Instruments can be manufactured.
