Abstract

<P>PROBLEM TO BE SOLVED: To provide a discharge lamp socket which can be fixed on rails of different width dimensions. <P>SOLUTION: In the fluorescent lamp socket, a socket main body 13 is provided with a movable fitting 12 which can move to match a width of a fixing rail 11. The movable fitting 12 is composed of a pair of movable pieces 15, a guide member 16 for guiding the pair of the movable pieces 15 to a direction of a width of the rail 11, and a spring 17 of an elastic member which can adjust a distance between the pair of the movable pieces 15. On an end portion of each of the movable piece 15 opposite to the spring 17, there is formed a groove 15a which can be locked with a side end portion of the rail 11. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a discharge lamp unit that is attached by being inserted into a rail that holds a discharge lamp such as a fluorescent lamp.

  Sockets for fluorescent lamps vary widely depending on the wattage, tube diameter, and manufacturer, and there are many types of sockets with different specifications depending on the age.

  Many socket types in the old age are in lots up, and renovation is thriving. Nowadays, many appliances cannot be procured, causing problems.

  In particular, the old type of sockets for fluorescent lamps occupies the majority of the so-called “turret type”. As shown in FIG. 4, the turret type socket 1 is inserted and attached to the rail 2, but the rail width dimension X varies depending on the type.

In addition, there exists a thing of patent document 1 as an example which inserts and attaches a socket to a rail.
Japanese Utility Model Publication No. 5-23317

  Mounting rails of specific dimensions are prepared for each turret type socket. For this reason, if the socket is in a lot-up, the replacement of the socket in the renewal work of the lighting fixture will be the replacement of the entire lighting fixture.

  Then, an object of this invention is to provide the discharge lamp socket which can solve such a subject. An example of the object is to provide a discharge lamp socket that can be mounted on rails of various width dimensions.

  The present invention is a discharge lamp socket that is attached by being inserted into a rail that holds a discharge lamp. This is provided with a movable tool provided on the socket body and movable in accordance with the width of the rail.

  According to the present invention, it can be attached to rails of various width dimensions.

  Embodiments of the present invention will be described below with reference to the drawings. Here, a straight tube fluorescent lamp socket is taken as an example of the discharge lamp socket, but the present invention is not limited to this.

  FIG. 1 is a structural view of the fluorescent lamp socket of this embodiment as viewed from the longitudinal direction of the fluorescent lamp. As shown in FIG. 1, the fluorescent lamp socket of the present embodiment is provided with a movable body 12 that is movable in accordance with the width of the mounting rail 11 in the socket body 13. The socket body 13 has a base part of a straight tube fluorescent lamp 14. Further, the socket body 1 and the movable tool 12 may be configured to be separable.

  The movable tool 12 is a spring that is an elastic member that can adjust the distance between the pair of movable pieces 15, the guide member 16 that guides the pair of movable pieces 15 in the width direction of the rail 11, and the pair of movable pieces 15. 17. The spring 17 may be replaced with rubber or elastomer resin. A groove 15 a that can be engaged with the side end of the rail 11 is formed at the end of each movable piece 15 opposite to the spring 17.

  In such a movable tool 12, the distance between the pair of movable pieces 15 urged by the spring 17 is maintained at a predetermined distance by the guide member 16 (FIG. 2B). And the space | interval of the movable piece 15 can be shortened by pushing the movable piece 15 inward against the urging | biasing force of the spring 17 (FIG. 2 (a)).

  Therefore, by engaging the groove 15a of one movable piece 15 with the side end of one side of the rail 11, and engaging the groove 15a of the other movable piece 15 with the side end of the other side of the rail 11, various A fluorescent lamp socket can be attached to the rail 11 having a width.

  FIG. 3 shows an example of an old socket. As can be seen from the dimensions shown in this figure, the width of the rail to which the various sockets are attached is in the range of 30 to 43 mm. Therefore, if the movable tool 12 is configured so that the distance between the bottoms of the grooves 15a of the pair of movable pieces 15 can be freely adjusted between about 30 to 46 mm by the effect of the spring 17, the socket shown in FIG. Even if it becomes a lot-up, it will be possible to respond sufficiently.

  According to the present invention, it is possible to renew an old-type lighting fixture that cannot be renewed due to socket lot-up. In addition to products made in-house, products from other companies can be mounted on the rails of lighting fixtures to be renewed.

  This is effective in reducing costs and industrial waste, and allows for environmentally friendly renewal work.

  Although the present invention has been described with reference to the embodiments, the above embodiments can be appropriately changed without being limited to the illustrated shape without departing from the technical idea of the present invention.

It is the block diagram which looked at the fluorescent lamp socket of the present Example from the longitudinal direction of the fluorescent lamp. It is a figure for demonstrating the mechanism of the movable tool of the fluorescent lamp socket of a present Example. It is the figure which showed the example of the old socket. It is the figure which showed the existing socket and its mounting rail.
