(57) [Summary] [Purpose] To raise the instrument body so that it can be easily attached to the fixed body. In a lighting fixture in which a link mechanism (3) is provided on one side of a fixed body (1), and a fixture body (2) is vertically connected to the link mechanism (3), an inclined shape that can be fitted into the fixed body (1) on one side of the fixture body (2) The guide 10 was launched.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 This invention relates to a lighting fixture.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 4, there has been a lighting fixture having a one-sided link mechanism including a fixed body 50, a fixture body 51, and a link mechanism 52. The fixed body 50 is attached to the ceiling or the like in a container shape, and the instrument body 51 can be moved up and down by a link mechanism 52.

[0003]

[Problems to be solved by the device]

 In the conventional lighting fixture, when the fixture main body 51 is raised and attached to the fixed body 50, the other side of the fixture main body 51 without the link mechanism 52 is raised so that the other side of the fixture main body 51 enters earlier than the one side. It will be. However, since there is no fixing means such as a link mechanism on the other side of the instrument main body 51, there is a problem that it cannot be easily fitted into the fixed body 50 due to twisting or the like.

Therefore, an object of the present invention is to provide a lighting fixture in which the fixture body can be easily raised and attached to the fixed body.

[0005]

[Means for Solving the Problems]

 The lighting fixture of the present invention is a lighting fixture in which a link mechanism is provided on one side of a fixed body, and the fixture main body is connected to the link mechanism so that the fixture main body can be moved up and down. It is characterized by the fact that a guide of the shape is launched.

[0006]

[Action]

 According to the structure of the present invention, since the guide is raised, the instrument body enters the fixed body from the guide when the instrument body is raised. This guide is inclined and is positioned with respect to the fixed body because it is provided on one side of the instrument body with the link mechanism. Therefore, the guide can be easily fitted into the fixed body. Once the guide is inserted, the fixture main body sequentially enters the fixed body from one side to the other, and the workability of attaching the fixture main body is improved.

【Example】

 A lighting apparatus according to an embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 is a vessel-shaped fixed body installed in Amai or the like. A fixture main body 2 of the lighting fixture is attached to one side of the fixed body 1 via a link mechanism 3 so as to rotate and rise and descend. The link mechanism 3 includes two links 4,5, a fixed portion 6 on the side of the fixed body 1 in which one ends of the links 4,5 are rotatably mounted, and the other ends of the links 4,5 are rotatable. It is provided with a pivotally attached instrument main body 2 side attachment portion 7. One side of the instrument body 2 is detachably attached to the attachment portion 7 by engaging and disengaging the hook-shaped locking portion 8 and the hole-shaped locked portion 9. Further, as shown in FIG. 2, a pair of guides 10 and 10 are erected on a part of the mounting portion 7. The pair of guides 10, 10 are slanted inward, and are configured to be easily fitted to both side walls 1a, 1a of the fixed body 1. Then, as shown in FIG. 1, when the one side of the instrument body 2 rises after the other side due to gravity balance, that is, the sagging angle θ of one link 4 is 30 ° ± 10 ° (the instrument body 2 However, the guide 10 is designed so that a part of the guide 10 fits into the fixed body 1. In the instrument body 2, 11 is a lamp and 12 is a socket.

Next, the lifting operation of this lighting equipment will be described. Since the link mechanism 3 rotates about 90 ° when the instrument body 2 is lowered, the instrument body 2 is substantially vertical. When raising the instrument body 2 from this state, the other side of the instrument body 2 is lifted and raised. There is a position where the rise of one side of the instrument main body 2 comes after the rise of the other side due to gravity balance, and the guide 10 enters the fixed body 1 at this position. Here, this guide 10 is inclined and is positioned with respect to the fixed body 1 because it is provided on the side where the link mechanism 3 is located. Therefore, the guide 10 can be easily fitted into the fixed body 1. When the guide 10 enters the fixed body 1, the instrument body 2 sequentially enters the fixed body 1 from one side to the other side.

In this embodiment, since it is configured as described above, without paying attention to the positional relation between the tool body 2 and the fixed body 1, the tool body 2 can be fitted into the fixed body 1 only by raising it. Can be installed. Therefore, lamp replacement, ballast replacement, reflector cleaning, equipment inspection, etc. can be easily performed without going up to a high place. Although the guide 10 is provided on the attachment portion 7 of the link mechanism 3, the guide 10 may be provided directly on the instrument body 2.

[0010]

[Effect of the device]

 According to the luminaire of the present invention, since the guide is raised, the fixture main body enters the fixed body from the guide when the fixture main body is raised. This guide is inclined and is positioned with respect to the fixed body because it is provided on one side of the instrument body with the link mechanism. Therefore, the guide can be easily fitted into the fixed body. Once the guide is inserted, the main body of the device enters the fixed body from one side to the other side. Therefore, without paying attention to the positional relationship between the fixture body and the fixed body, the fixture body can be inserted into the fixed body only by raising it, and workability is particularly good when the lighting fixture is mounted at a high position. Is.
