Description

  The present invention relates to a connecting fixture for a lighting fixture and a lighting device capable of rationally connecting a straight tube type lighting fixture suspended from the lower surface of a lighting cover.

  As described in Patent Document 1, the applicant of the present application has previously proposed a continuous fluorescent lamp system in which a straight tube fluorescent lamp apparatus is rationally mounted. In this system, a raceway or a metal duct is used for the fixture body, and a straight tube fluorescent lamp fixture is directly attached to a raceway or a metal duct used for wiring or piping. That is, a fixed substrate is mounted on an opening of a raceway or the like, and a fixture such as a socket or a ballast is detachably attached to the fixed substrate. And, when connecting straight tube type lighting fixtures, adopt a configuration in which a conductor for power supply is buried in each fixed board and electrically connected with a connector that connects conductors of adjacent fixed boards. ing.

  On the other hand, Patent Literature 2 and Patent Literature 3 describe connection fittings that connect lighting devices that are directly screwed and fixed to a ceiling surface without using a raceway or a metal duct. The connecting metal fitting of Patent Document 2 is configured for the purpose of omitting the screwing operation at the time of connecting metal fitting construction, and the connecting metal fitting of Patent Document 3 is configured for the purpose of absorbing the manufacturing error of the instrument body. . Each of the connection fittings adopts a configuration in which an attachment hole is opened in the top surface portion of the instrument body, and an end portion of the adjacent instrument body is connected between the fixed portion inserted in the attachment hole and the connection portion. .

  Since the connecting metal fitting of Patent Document 1 is mounted using a locking groove along the longitudinal side surface of the raceway or metal duct, the connector is also fitted into the locking groove along the longitudinal side surface of the fixed substrate. It was what had. Therefore, in order to use the connection metal fitting of patent document 1, it was restricted to the case where the raceway and metal duct which have a locking groove are used as an instrument main part.

  Moreover, the connection metal fittings described in Patent Document 2 and Patent Document 3 are for fixing the distance between the lighting devices that are screwed and fixed directly to the ceiling surface so that the lighting fixtures are firmly connected to each other. Is not configured. However, when connecting a straight tube type lighting fixture suspended from the lower surface of the lighting cover, the lighting fixture is not directly screwed to the ceiling surface, so it is necessary to increase the coupling force between the lighting fixtures.

  On the other hand, for the purpose of replacing fluorescent lamps, “straight tube fluorescent lamp type LED lamps” of various specifications having structural compatibility with conventional fluorescent lamps such as a base shape and a length are provided. However, unlike a fluorescent tube, this “straight tube fluorescent lamp type LED lamp” requires a dedicated control device (LED driver) instead of a ballast or lighting means.

  Currently, the following three types of “straight tube fluorescent lamp type LED lamp” are provided. The first type is a direct connection type with a commercial power source with a built-in DC power source, the second type is a new DC input type without a built-in DC power source, and the third type is an existing ballast connection type with a built-in DC power source. In addition, the first and second types include a both-end-pin feeding method and a one-side-pin feeding method, respectively.

  As a result, the illumination device to which the “straight tube fluorescent lamp type LED lamp” is attached is suitable to be attached to the lower surface of the illumination cover so that it can be easily attached and detached even if the type and method of the luminaire are different. . Moreover, when connecting the lighting fixtures to each other, it is necessary to connect them so that electrical connections such as connectors installed in the respective lighting fixtures are not separated, and to increase the connection strength and ensure the mechanical connection. Become.

  Therefore, the present invention has been created to solve the above-described problems, and a connecting fixture for lighting fixtures capable of rationally and firmly connecting straight tube type lighting fixtures attached to the lower surface of the lighting cover. And it aims at provision of an illuminating device.

  In order to achieve the above-mentioned object, the first means in the present invention is a connection fitting for connecting a lighting fixture 20 attached to the lower surface opening of the bowl-shaped lighting cover 10 to which the straight tube lamp P is attached. The instrument 20 includes a strip-shaped reflector 21 having a U-shaped cross section, a socket 22 for a straight tube lamp P to be attached to both longitudinal ends of the reflector 21, and the socket 22 and the adjacent straight tube shape. A connector 23 for supplying power to the socket 22 for the lamp P, and at both longitudinal end portions of the reflecting plate 21 such that the longitudinal both end portions of the adjacent reflecting plates 21 of the continuous lighting fixture 20 are overlapped with each other. Each pair of downward bending contact pieces 21A is formed, and the connection fitting 1 is opened to the connection body 2 with an elastic band plate-like connection body 2 fitted around the longitudinal end portion of the reflection plate 21.

As a result, the connecting fitting 1 can be easily attached and detached. In addition, since the insertion port 4 for inserting the string 24A for the canopy switch 24 is provided in a notch shape between the insertion holes 3, even when the lighting fixture 20 to which the canopy switch 24 is attached is connected, it is extremely easy. The string 24A can be passed through.

  As in claim 3, an opening 21B is formed between the bending contact pieces 21A, and the lighting fixture 20 configured to visually check the connection state of the connector 23 from the opening 21B, and the long end of the reflector 21 When the connection fitting 1 is not mounted by providing the elastic band plate-like connection body 2 that fits around and closes the opening 21B, the connection state of the connector 23 is visually observed from the opening 21B. Can do. Further, when the connecting fitting 1 is mounted, it is possible to rationally and firmly connect the straight-tube luminaires while closing the opening 21B. Furthermore, by adopting a configuration in which the lighting fixture 20 is mounted on the lighting cover 10, it is possible to easily mount different types of straight tube LED lamps to the lighting fixture 20 in addition to the straight tube fluorescent lamp. Is now possible.
