Description

[Detailed description of the invention] The present invention relates to a lighting fixture in which a U-shaped case containing a ballast body is inserted into a U-shaped holder, and the present invention is designed so that the case can be easily inserted into the holder. This is what I did.

This type of lighting equipment has a U-shaped holder 2 having a pair of side walls 1 at both ends in the width direction, as shown in FIG.
In addition to attaching a discharge lamp, a glow lamp, and other appliances to the holder, a U-shaped case 4 containing a ballast main body 3 is inserted into the holder to attach a ballast 5 for the discharge lamp. However, the holder 2 is elongated because the discharge lamp is long, and the wall thickness is thin to minimize the amount of material used for the device, so it is difficult to insert the case 4 into the holder 1, making it difficult to insert the case 4 smoothly. The holder 2 could be damaged by the case 4 during insertion.

The present invention solves the above problems and is characterized by a roughly U-shaped holder that has a pair of side walls at both ends in the width direction, and a ballast body that has a pair of side walls at both ends in the width direction. In a lighting fixture in which a stored approximately U-shaped case is inserted into the holder with both side walls of the case aligned with both sides of the holder, the case is inserted into the insertion side end of each side wall of the case while being inclined inward in the width direction. The point is that a guide piece is provided that protrudes in the direction.

Hereinafter, the present invention will be explained according to the illustrated embodiment. In FIGS. 2 and 3, reference numeral 11 denotes a U-shaped holder having a pair of side walls 12 at both ends in the width direction, with the open side facing downward. It is fixed to an attached member 13 such as a ceiling window. This holder 11 is formed into an elongated shape, and a pair of discharge lamps 14 in the width direction are supported by the holder 11 in a downwardly protruding manner through sockets 15, and also a glow lamp and the like (not shown) are also supported. A V-shaped reflector 15 is placed between the holder 11 and the discharge lamp 14 to block the upper part of the discharge lamp 14, and its upper end is attached to the mounting member 13 with screws 16. Reference numeral 17 denotes a ballast for a discharge lamp, which is composed of a ballast main body 18, a case 19 for storing the ballast main body 18, and a cover 20 for tightening the ballast main body 18 together with the case 19. The ballast main body 18 includes an iron core 21 and a coil 22 wound around the iron core 21, and the coil 22 has upper and lower protrusions 22a and 22b that protrude upward and downward from the center of the upper and lower surfaces of the iron core 21, respectively. The case 19 is formed into a substantially U-shape having a bottom wall 23 and a pair of side walls 24 projecting upward from both ends of the bottom wall 23 in the width direction.The side walls 24 sandwich both sides of the iron core 21 in the width direction, and the upper end thereof The portion protrudes upward from the upper surface of the iron core 21. Both end portions in the width direction of the bottom wall 23 abut against the lower surface of the iron core 21, and a U-shaped coil storage portion 23a is formed in the center portion in the width direction and protrudes downward in a U-shape. is stored. The cover 20 includes a U-shaped coil storage portion 25 projecting upward, a pair of pressing portions 26 projecting outward in the width direction from both widthwise ends of the coil storage portion 25, and a pair of pressing portions 26 extending upward from the widthwise outer ends of the respective pressing portions 26. It is formed into a hat shape with a pair of protruding ribs 27, the pressing part 26 is in contact with the upper surface of the iron core 21, the coil storage part 25 stores the upper protrusion part 22a of the coil 22, and the upper end thereof has a pair of ribs 27. A mounting portion 28 is provided to protrude outward in the longitudinal direction. Each rib 27 is overlapped with the inner surface of the upper end of each side wall 27 of the case 19, and is crimped to the side wall 27 by caulking a caulking piece 29 protruding from the upper end of the side wall 27. The stabilizer 17 is attached to the holder 11 and the both side walls 12 of the holder 11 are attached to the side walls 2 of the case 19.
4 is fitted inside the cover 20 and fixed thereto with screws 30 or the like via the mounting portion 28 of the cover 20.
Reference numeral 31 denotes a guide piece provided upwardly projecting from both ends of the upper end of each side wall 24 in the longitudinal direction so as to be inclined inward in the width direction, and the upper end thereof is at the same or lower position with respect to the upper surface of the coil storage portion 25 of the cover 20. . This guide piece 31 serves as a guide when inserting the case 19 into the holder 11, so that the case 19 can be inserted into the holder 11 smoothly, and there is no risk of damaging the holder 11 by the case 19 during insertion. It disappears.

According to the present invention, a guide piece is provided at the insertion side end of each side wall of the case, so that the guide piece inclines inward in the width direction and projects in the insertion direction, so that the guide piece is used when inserting the case into the holder. This acts as a guide, and therefore allows the case to be inserted into the holder smoothly, and prevents the holder from being damaged by the case during insertion.
