Description

  The present invention relates to a lighting fixture, and more particularly to a technique for attaching a socket base to a main body.

  Conventionally, socket bases 3 for attaching sockets 2 are arranged in the vicinity of both ends in the longitudinal direction of the main body 1 in the shape of a horizontally elongated box that opens downward, so that the socket base 3 is attached to the main body 1. What is made is known. (For example, refer to Patent Document 1).

  By the way, in order to place and mount the socket base 3 in the main body 1 opened downward, conventionally, the screw tool 21 is inserted from the screw tool insertion hole provided in the upper surface piece 20 of the main body 1 and arranged in the main body 1. It was attached by screwing onto the upper end of the socket base 3.

  For this reason, in order to deal with lamps 14 having different light shielding angles using the same main body 1, a plurality of types of socket bases 3 having different heights are created as shown in FIGS. According to the difference, the socket base 3 having a desired light shielding angle is selected from a plurality of types of socket bases 3 having different heights and attached.

  For example, FIGS. 11 and 12 show a case where the light distribution member 16 such as a louver is not attached, and FIGS. 13 and 14 show a case where the light distribution member 16 such as a louver is attached to the lower part in the main body 1. In FIG. 14, since the light distribution member 16 such as a louver is attached, the position of the lamp in the main body 1 is higher than the case of FIG. 12 by the height of the light distribution member 16 such as a louver. Therefore, the light shielding angle in the case of FIG. 14 in which the louver is provided is larger than the light shielding angle in the case of FIG. 12 in which the light distribution member 16 such as a louver is not provided (for example, the light shielding angle in FIG. 14 is 30 °).

  For this reason, conventionally, it is necessary to prepare a plurality of types of socket bases 3 having different heights, and there is a problem that the cost increases.

In the figure, reference numeral 13 denotes a reflector.
