Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a direct-mounted fluorescent lamp luminaire, and more particularly to improvement of a simple mounting structure for a reflector having a substantially inverted trapezoidal cross section.

[0002]

2. Description of the Related Art Generally, in a direct-attached fluorescent lamp lighting fixture, for example, a socket attachment is fixed to both ends of a main body of an elongated channel, and a reflector having a substantially inverted trapezoidal cross section is used with a decorative screw. Fixed to the socket fixture.

According to this structure, a relatively low-cost luminaire can be obtained because of its simple structure. However, after fixing the main body of the luminaire to the ceiling surface, when the reflector is attached to the socket fixture. Since the mounting hole of the reflector and the mounting hole of the socket mounting tool must be aligned with each other and the decorative screw must be screwed in, the mounting work is troublesome.
In particular, in the case of a long reflector such as 2.4 m, it is necessary for two workers to support the both ends of the reflector while performing the mounting work, which significantly impairs work efficiency. There's a problem.

[0004]

Therefore, conventionally, in order to solve such a problem, a direct attachment type fluorescent lamp illuminator shown in FIGS.
21824). This lighting fixture has a ceiling surface A
A device body B having a long and narrow channel shape fixed to the end and having locking portions B2 and B2 formed by curling formed over the entire length at the edges of the rising edges B1 and B1 on both sides.
And socket fixtures C arranged at both ends of the instrument body B
And the sockets D and D attached to the socket fixture C
And the engaging portions E1 and E each having a substantially inverted trapezoidal cross section and formed by curling processing formed on both end edges over the entire length.
1 and a reflection plate E having an engaging portion E
1, the inner dimension W1 of E1 is the outer dimension W2 of the engaging portions B2, B2
It is set smaller.

In this luminaire, as shown in FIG. 7, when the reflector E is attached to the main body B of the illuminator, when the reflector E is pushed up in the direction of the arrow in the drawing, the engaging portions E1 and E1 are engaged with the engaging portion B2. It passes while being pushed outward by B2. Then, after passing through, the reflector E returns to its original shape, and as shown in FIG. 6, the lower portions of the engaging portions E1 and E1 are engaged with the engaging portions B2 and B2 to complete the attachment.

According to this proposal, even if the length of the reflector E is long, the reflector E can be easily attached to the instrument body B by simply pressing it, so that the working efficiency can be remarkably improved. It is a thing.

However, in this luminaire, since the reflector E is directly attached to the luminaire body B, both widths must be set to be substantially the same. For this reason, if one of the widths of the instrument body B or the reflector E is changed,
There is a problem that the design change is extremely complicated because the other must be changed without fail. Moreover, the reflection plate E and the instrument body B are attached to each other by the engagement portion E formed over the entire length.
1, E1 and the locking portions B2, B2 are locked, so a considerably large pushing force is required at this time,
There is also a problem that it is slightly difficult to install.

Therefore, it is an object of the present invention to improve the attachment of the reflector by a relatively simple structure, and to change the body of the instrument directly without depending on the shape of the reflector. It is to provide a lighting fixture.

[0009]

SUMMARY OF THE INVENTION Therefore, in order to achieve the above-mentioned object, the present invention provides an elongated channel-shaped instrument main body and a socket attachment having a substantially inverted trapezoidal cross section disposed at both ends of the instrument main body. And a reflector plate having a substantially inverted trapezoidal cross section and having an engaging portion formed by curling over the entire length at the end portion, the reflector plate serving as a socket fixture and a socket fixture. It is attached by elastically locking the engaging portions to the engaging portions formed on both sides,
In a second aspect of the present invention, the socket attachment is formed on an inclined socket attachment portion, an engagement portion that is bent substantially horizontally continuously from the socket attachment portion, and an extended end of the engagement portion. It is characterized in that it is composed of a mounting part to the instrument body.

[0010]

According to the above-mentioned structure, the reflecting plate having a substantially inverted trapezoidal cross section has the engaging portion locked only to the locking portion formed on the socket fixture. For this reason, the two can be attached easily because the two can be locked smoothly. In particular,
Since the reflector is directly locked to the socket fixture,
It can be attached to the socket fixture irrespective of how the shape of the instrument body is changed. Therefore, it is possible to easily meet various requirements for the lighting equipment.
