Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a ceiling-embedded lighting fixture in which the fixture body and ballast are installed separately.

[Background Art] In conventional lighting equipment such as ceiling-mounted downlights, where the ballast and electronic starter are easily affected by the heat generated by the lamp, as shown in FIG. Parts such as a ballast, an electronic starter, and a terminal block were housed in a case 2 and attached to a ceiling construction material 4 near the appliance body 1. However, with this conventional structure, it is not easy to insert your hand through the embedded hole 10 of the fixture body 1 and attach the metal case 2 during maintenance, and the wiring is usually connected after installation from the ceiling. Because of this, there were drawbacks such as poor work efficiency and a large number of man-hours.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to provide a lighting device of this type whose metal case can be easily attached and removed during maintenance. is to provide.

[Disclosure of the invention] The lighting equipment according to the invention includes a ballast, an electronic starter, and a metal case separate from the equipment body.
An inverted L-shaped mounting bracket that houses electrical components such as a terminal block and has a horizontal piece fixed to a ceiling construction material via a spacer is connected to the horizontal piece at the end on the appliance body side. The metal case is attached to a vertical piece of the instrument body, and the metal case is characterized in that the metal case can be attached and detached with a single touch from an embedded hole in the instrument body during maintenance.

[Embodiment] Fig. 1 shows an embodiment of the present invention, in which components such as a ballast, an electronic starter, and a terminal block are housed in a metal case 2 that is separate from the device body 1.
The horizontal piece 3a is attached to the ceiling construction material 4 via the spacer 9.
The metal case 2 is attached to the vertical piece 3b that is connected to the horizontal piece 3a at the end of the inverted L-shaped mounting bracket 3 fixed to the ceiling edge (for example, a ceiling edge). It is installed.

As shown in FIG. 2, a hooking piece 7 and an engaging piece 5 are protruded from the upper and lower ends of the back surface of the metal case 2, and the engaging piece 5 becomes wider from the base end to the distal end. It is formed into a trapezoid. Further, the engagement hole 6 of the mounting bracket 3 corresponding to this engagement piece 5 is formed into a trapezoid with a wider upper part, and the length d ₁ of its lower side is slightly smaller than the width d ₂ of the base end of the engagement piece 5. It is formed like this.

Furthermore, the hooking piece 7 protruding from the upper end of the metal case 2 is bent downward and slightly inward from its base end at a point approximately the same length as the thickness _d3 of the mounting bracket 3. The tip part 7a is bent diagonally outward, and in correspondence with the hooking piece 7, the upper edge of the vertical piece 3b of the mounting bracket 3 has the same width as the width _d4 of the base end of the hooking piece 7. A notch 8 is formed.

When assembling, as shown in FIG. While engaging the base end of the engagement hole 6 with the oblique side of the engagement hole 6,
The bottom edge of the notch 8 is held between the hook pieces 7, and at this time, due to the weight of the stabilizer, the engagement pieces 5 and the oblique sides of the engagement hole 6, each made of a metal plate, bite into each other, and The metal case 2 is stably supported by the mounting bracket 3 by the hooking piece 7 elastically compressing the mounting bracket 3.

According to the above configuration, since the metal case 2 is attached to the vertical piece 3a of the mounting bracket 3, during maintenance, as is clear from FIG. The metal case 2 can be easily attached and detached by inserting one's hand, and since the base end of the engagement piece 5 is engaged with the oblique side of the engagement hole 6, the trapezoidal shape can be formed by simply hooking it. There is no risk that the hypotenuses of the metal case 2 will bite into each other and cause the metal case 2 to wobble in the front-rear or left-right direction, and noise caused by the vibration of the ballast can be prevented.

[Effects of the invention] As described above, the lighting equipment according to the invention has a metal case that is formed separately from the main body of the equipment and houses parts such as a ballast, and the horizontal piece is fixed to the ceiling construction material via a spacer. The metal case is attached to the vertical piece that is connected to the horizontal piece at the end of the inverted L-shaped mounting bracket on the side of the device body, and the metal case is attached to the side surface of the device body. Because it is placed near the instrument body rather than directly to the
There are no restrictions on the reinforcement dimensions of the lighting fixture mounting portion, that is, the mounting dimensions of the ceiling construction material (ceiling edge), and the lighting fixture installation work can be easily performed. In addition, when maintaining the lighting equipment, workers do not have to go to the trouble of entering the ceiling, they can easily attach and remove the metal case by simply inserting their hand into the ceiling through the hole in the fixture body. This has the advantage that installation work for lighting equipment can be performed easily and quickly.
