Abstract

<P>PROBLEM TO BE SOLVED: To provide a lighting fixture provided with sockets capable of corresponding to circular fluorescent lamps having diameters different from each other. <P>SOLUTION: The lighting fixture is formed by fixing a reflection plate 2 on a lower face of a main body 1 to be mounted on a ceiling, and pinching and fixing sockets 6, on which the circular fluorescent lamps 3, 4, 5 are mounted by the main body 1 and the reflection plate 2. By arranging a first convex part 7 and a second convex part 8 on the side face of the socket 6 on the positions different in an inside direction and an outside direction respectively, a notched edge 9 of the reflection plate is selectively locked to the first convex part 7 or the second convex part 8 corresponding to the fluorescent lamps 3, 4, 5 having diameters different from each other. A plurality of almost L-shaped locking parts 10 formed on an upper face of the socket 6 are locked to the main body 1 by sliding the socket inward after inserting the locking parts into holes 11 on the main body. A detent of the socket 6 is formed by selectively locking the first convex part 7 or the second convex part 8 into the notched edge 9 of the reflection plate 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a luminaire provided with a socket that can accommodate annular fluorescent lamps having different outer diameters.

In patent document 1, it is the lighting fixture which fixed the reflecting plate to the lower surface of the main body, and pinched | interposed the socket which mounts | wears with a cyclic | annular fluorescent lamp with a main body and a reflecting plate, Comprising: A convex part (ridge part) is formed in the side surface of a socket. By providing, the notch edge of a reflecting plate is latched to the convex part.

  However, a socket to which two annular fluorescent lamps can be mounted is used, and there is no suggestion of an idea corresponding to an annular fluorescent lamp having a different outer diameter with one socket. In view of such problems to be solved, an object of the present invention is to provide a luminaire including a socket that can accommodate annular fluorescent lamps having different outer diameters.

  In summary, the present invention is a lighting fixture in which a reflector is fixed to the lower surface of a main body, and a socket for mounting an annular fluorescent lamp is sandwiched between the main body and the reflector, and is located at different positions in the inner and outer directions on the side of the socket. A lighting fixture in which the cutout edge of the reflector is selectively locked to the first convex portion or the second convex portion corresponding to the fluorescent lamps having different outer diameters by providing the first convex portion and the second convex portion, respectively. It is.

  According to the present invention, the notch edge of the reflector can be selectively locked to the first convex part or the second convex part of the socket side surface corresponding to the fluorescent lamps having different outer diameters. Can easily handle fluorescent lamps.

  Next, an embodiment of the present invention will be described. However, this is merely an exemplary embodiment adopted based on the present invention, and the present invention should not be limitedly interpreted based on matters specific to the embodiment. The technical scope of the present invention should be determined based on the matters shown in the claims of the claims and matters substantially equivalent to the matters.

  In the illustrated embodiment, a reflector 2 is fixed to a lower surface of a main body 1 attached to a ceiling with a screw or the like, and a socket 6 for mounting an annular fluorescent lamp 3, 4 or 5 is sandwiched between the main body 1 and the reflector 2. It is a stopped lighting fixture, and by providing the first convex portion 7 and the second convex portion 8 at different positions in the inner and outer directions on the side surface of the socket 6, it corresponds to the fluorescent lamps 3, 4, and 5 having different outer diameters. Thus, the lighting fixture is such that the notch edge 9 of the reflector 2 is selectively locked to the first convex portion 7 or the second convex portion 8.

  The plurality of substantially L-shaped locking portions 10 formed on the upper surface of the socket 6 are inserted into the holes 11 of the main body 1 and then locked to the main body 1 by sliding the socket 6 inward. When the notch edge 9 of the reflecting plate 2 is selectively locked to the convex portion 7 or the second convex portion 8, the socket 6 is detented. 1 and FIG. 5 are when the large-diameter double annular fluorescent lamp 3 is used, FIGS. 2 and 6 are when the medium-diameter double annular fluorescent lamp 4 is used, and FIGS. 3, 7 and 8 are small diameters. The double annular fluorescent lamp 5 is used.

  1 and 5, the notched edge 9 of the reflecting plate 2 is locked to the oblique lower edge of the first projecting portion 7, and the notched edge of the reflecting plate 2 is engaged with the second projecting portion 8 in FIGS. 2 and 6. 9, and in FIG. 3, FIG. 7 and FIG. 8, the notch edge 9 of the reflection plate 2 is locked to the second convex portion 8. 3, 7, and 8, the height of the socket mounting surface 12 of the main body 1 is recessed downward unlike the other main bodies 1 to correspond to fluorescent lamps 5 having different outer diameters, that is, small-diameter fluorescent lamps 5. And make them different. The purpose is to prevent the fluorescent lamp 5 having the smallest inner diameter from coming into contact with the lower end surface of the reflector 2.

  According to this embodiment, the notch edge 9 of the reflector 2 is selectively formed on the first convex portion 7 or the second convex portion 8 on the side surface of the socket 6 corresponding to the fluorescent lamps 3, 4, and 5 having different outer diameters. Since it can lock, it can respond easily to the annular fluorescent lamps 3, 4, and 5 having different outer diameters.
