Description

[Detailed description of the invention] This invention relates to a lighting equipment reflector. BACKGROUND ART Conventionally, in a straight tube type fluorescent lamp lighting fixture for one lamp without a buffer, a downward trapezoidal groove-shaped reflector plate 1 has been used as shown in FIG. 2 is a fluorescent lamp. On the other hand, in order to streamline production by sharing parts, even for lighting fixtures with double-sided
The reflector 1 shown in FIG. 1 is used. In this case, the second
As shown in the figures and FIG. 3, each buffle 4 is attached to a pair of buffle attachment plates 3 provided along the inner surface of the reflector 1. The full mounting plate 3 is fixed to the reflector plate 1 with set screws 5. The baffle 4 has a retaining pawl 7 that is inserted into a slit 6 provided in the buffle mounting plate 3, and is attached to the baffle mounting plate 3 by bending the retaining pawl 7. The baffle mounting plate 3 has folded portions 3a on its upper and lower edges in order to provide space for a retaining claw between it and the inner surface of the reflector plate 1. However, due to the folded portion 3a, the buttful mounting plate 3 has a thickness equivalent to two sheets, which is visible from below, which is not desirable in terms of appearance.

Therefore, the purpose of this invention is to provide a design that can be used both with and without a full butt, and when used with a full butt, the buttful mounting plate is not visible to people and a clean appearance can be obtained. It is an object of the present invention to provide a reflector for lighting equipment.

An embodiment of this invention is shown in FIGS. 4 to 6. In the figure, reference numeral 8 denotes a reflecting plate, which is formed in the shape of a downward trapezoidal groove, and grooves 9' are bent along the longitudinal direction on the inner surfaces of both flanges 8a. An L-shaped reinforcing flange 8b is provided at the lower edge of both flanges 8a, bending outward and rising up. 9
are a pair of buttful mounting plates, which are formed to have a width that fits into the groove 9' of the reflecting plate 8. Reference numeral 10 denotes buffles attached to the buffle mounting plate 9 at appropriate intervals in the longitudinal direction. The baffle 10 has retaining pawls 11 at both ends, and is fixed to the buffle mounting plate 9 by inserting the retaining pawls 11 into the slits 12 of the baffle mounting plate 9 and folding them back. Batsuful mounting plate 9
has a folded part 9a folded outward at the upper and lower edges. The baffle 10 is fitted into the groove 9' of the reflector 8 and fixed to the reflector 8 with a set screw (not shown). The depth of the groove 9' of the reflecting plate 8 is approximately the same as the thickness of the buttful mounting plate 9.
The inner surface of the reflector plate 8 and the inner surface of the reflector plate 8 are flush with each other.

With this structure, when the buttful 10 is attached, the buttful mounting plate 9 is housed in the groove 9' and is not visible from below, resulting in a clean appearance. In addition, when the baffle 10 is not provided, the groove 9' has a decorative effect, and a good appearance can also be obtained in this case. Furthermore, the groove 9' provides a reinforcing effect to prevent the flange 8a from warping. In this way, the reflector 8 can be used in common with the full-bump and without the full-bump,
Moreover, a good appearance can be obtained in either case.

FIGS. 7 to 10 show modifications of the buttful mounting structure. In other words, there is an inverted T on the full mounting plate 9.
A cut-and-raised claw 13 in the shape of a letter is provided, and its cut-and-raised hole 14
Engagement claws 15 that engage with are provided at both ends of the buttful 10. Cut-and-raise claw 13 of the full mounting plate 9
Before being raised, a gap P is formed between the tip of the cut-and-raise claw 13 and the inner surface of the cut-and-raise hole 14, in which the engagement claw 15 of the buttful 10 is accommodated. This gap P is approximately the same as the plate thickness of the engaging claw 15, but in the case of press-fitting, it is made narrower than the plate thickness. The width q of the wide part of the cut hole 14 is the width of the tip of the engaging claw 15.
It is formed slightly narrower than q′. The width r of the narrow portion of the cut hole 14 is slightly wider than the width r' of the base of the engagement claw 15.

When constructed in this way, the cut-and-raised claw 13 of the buttful mounting plate 9 is raised, and the engaging claw 15 of the buttful 10 is inserted into the cut-and-raised hole 14, and then the cut-and-raised claw 13 is used as the base. Return it and fix Batsuful 10.
Therefore, the fixing work is easier than in the case of bending and fixing the retaining claw 11 of the buttful 10 as in the example shown in FIG. 4, and productivity is improved. The rest is the same as the first embodiment.

As mentioned above, the lighting equipment reflector of this invention is
It is formed in the shape of a downward trapezoidal groove and has grooves along the longitudinal direction on the inner surface of both flanges, and this groove has a cross-sectional shape that allows the buttful mounting plate to fit, so when the buttful is attached. It can be used in common with the case without a buttful, and when it is with a buttful, the buttful mounting plate is not visible to the person who is housed in the groove, and a good appearance is obtained, and when it is not made with a buttful, Also, the grooves have a decorative effect to provide a good appearance, and the grooves also provide reinforcement of the flange.
