(57) [Summary] [Purpose] It is not necessary to climb to the height of the fixture, and when the lamp body descends, the power is shut off to facilitate maintenance. [Structure] The lamp body 2 is rotatable and detachable with respect to the body 1 by a hinge portion 9. The connector 10 supplies and shuts off the power from the main body 1 to the lamp main body 2. When the lamp body 2 is tilted and lowered from the body 1 via the hinge portion 9, the connection terminal 12 of the connector 10 is separated from the connection terminal 11, so that the power supply is cut off.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lighting fixture installed on a lower surface of a ceiling.

[0002]

[Prior Art]

 Conventionally, this type of lighting fixture is composed of a main body installed on the ceiling surface and a lamp main body mounted on the lower surface of the main body, and the lamp main body is composed of a lamp, a ballast, a reflector, etc. Has been done. The lamp body has a structure that can be tilted and lowered when replacing the lamp, etc., and the power line between the lamp body and the lamp body was connected by taping or a detachable connector by hand. ..

[0003]

[Problems to be solved by the device]

 In the case of such a conventional example, when the lamp body is tilted down from the body and lowered, the power supply line is still connected and the power is still applied to the lamp, which is dangerous. In addition, during maintenance of the lighting equipment, it was necessary to climb to the height of the lighting equipment. Furthermore, during maintenance, the main power supply had to be shut off to keep the power on or to perform work safely.

The present invention has been provided in view of the above-mentioned points, and it is not necessary to climb to the height of the fixture, and the power is shut off when the lamp body descends to facilitate maintenance. Is provided.

[0005]

[Means for Solving the Problems]

 The present invention comprises a main body disposed on a ceiling surface and the like, and a lamp main body mounted on the lower surface of the main body via a hinge part of which one end is rotatable and detachable. The power is supplied to the lamp by a connector that is contacted when the lamp body is mounted on the bottom surface of the lamp body.

[0006]

[Action]

 Then, by rotating the lamp main body with respect to the main body to lower or remove it, the maintenance of the main body of the lamp is facilitated, and when the lamp main body is tilted and lowered by the connector, The power supply to the main body can be facilitated, and lamps can be replaced safely, fixtures can be cleaned, and parts such as ballasts can be replaced safely.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the main body 1 is installed on the lower surface of the ceiling, and the lamp main body 2 is mounted on the lower surface of the main body 1. The lamp body 2 is composed of a chassis 3 also serving as a reflector, a ballast 4, a socket 5, a lamp 6 and the like arranged on the upper surface of the chassis 3.

Here, a shaft 7 is provided at one end of the lower surface of the main body 1, and a semicircular locking piece 8 is formed on the lamp main body 2 so as to be hooked on the shaft 7. And the locking piece 8 constitute a hinge portion 9. Therefore, the lamp body 2 is rotatable and detachable with respect to the body 1 by the hinge portion 9. Therefore, it is easy to attach and detach the lamp body 2 to and from the body 1.

Power supply and cutoff from the main body 1 to the lamp main body 2 are performed by a connector 10. A connection terminal 11 is provided on the lower surface of the main body 1, and a connection end that can be connected to and disconnected from the connection terminal 11 is provided. The child 12 is formed on the upper surface of the lamp body 2. The connection device 10 is composed of both the connection terminals 11 and 12. In addition, an appropriate means for fixing the other end of the lamp body 2 is formed on the other end side of the main body 1.

FIG. 1 shows a state in which the lamp body 2 is tilted and lowered from the body 1 via the hinge portion 9. In this case, the connector 10 separates the connection terminal 12 from the connection terminal 11, and therefore the power source is It has been cut off. Further, when the lamp body 2 is lifted and attached to the body 1, both the connection terminals 11 and 12 are contact-connected and the lamp body 2 is supplied with power.

Second Embodiment FIG. 2 shows a second embodiment, in which the connector 10 is provided on the side opposite to the hinge portion 9. In this case, when the lamp body 2 is lowered, the power is immediately shut off, which is safe and the connector 10 is unlikely to be subjected to excessive force when being attached or detached. Example 3 FIGS. 3 and 4 show Example 3 in which the chassis 3 and the reflector 13 are separate bodies. In this case, the reflector 13 is attached by the latch 14. In addition, the reflector 14 and the like can easily change the reflecting plate, the louver, and the like.

Example 4 Example 4 is shown in FIG. This is a case where the hinge portion 9 is of an arm type, and the arm 15 is connected to the main body 1 and the lamp body 2 so as to be rotatable and detachable. The hinge portion 9 allows the lamp body 2 to be lowered to 90 degrees with respect to the body 1.

[0013]

[Effect of the device]

 As described above, the present invention includes the main body arranged on the ceiling surface and the like, and the lamp main body attached to the lower surface of the main body via the hinge part of which one end is rotatable and detachable. Since the power supply from the lamp body to the lamp body is made by the connector that is contact-connected when the lamp body is mounted on the bottom surface of the lamp body, rotate the lamp body with respect to the lamp body to move it down or out. Therefore, maintenance of the lamp body can be facilitated without climbing to the fixture height, and one side is a hinge part, so that one side of the lamp body is fixed, and lamp replacement is possible. In addition, when the lamp body is tilted and lowered by the connector, it is easy to supply power to the lamp body and safely replace the lamp, clean the fixture, and replace parts such as ballast. It is possible to Since the power is cut off when the lamp body descends, it is possible to maintain the fixture without cutting off the main power source, and the lamp body can be attached to and detached from the body easily, and parts can be easily replaced. It is effective.
