Japanese Unexamined Patent Publication No. 2017-413326

In a lighting fixture as disclosed in Patent Document 1, functional parts such as a motion sensor, an illuminance sensor, an emergency light unit, or a wireless unit may be attached later as needed. The functional component has, for example, a configuration in which a sensor substrate and a sensor member are provided inside a rectangular case member formed by an outer shell. This functional component is attached so that only one of the plurality of outer surfaces of the case member is brought into contact with the stanchion frame of the luminaire. In order to stably attach the functional parts to the luminaire, it is necessary to increase the contact surface to be brought into contact with them. However, if the contact surface with the support column frame is made large, the case member becomes large, so that the weight of the functional component increases and it becomes inconvenient to handle. Further, when the case member becomes large, the appearance is deteriorated in terms of design, the amount of dust accumulated on the surface increases, and the burden of cleaning increases.

The present invention has been made to solve the above-mentioned problems, and it is possible to reduce the size and weight as a whole while ensuring the size of the contact surface to be brought into contact with the outer surface of the luminaire. The purpose is to provide functional parts that can be used.

The functional component according to the present invention is a functional component attached to a lighting fixture, and includes a case member forming an outer shell and a substrate housed inside the case member, and the case member is a first side surface. A second side surface portion extended from one end edge of the first side surface portion and brought into contact with the outer surface of the luminaire, an extended end edge of the second side surface portion, and the other end of the first side surface portion. It has a third side surface portion that is connected to the edge and is partially or entirely inclined with respect to the second side surface portion or curved so as to be recessed toward the inner side of the case member .

According to the functional component of the present invention, even if the size of the second side surface portion to be brought into contact with the outer surface of the luminaire is secured, a part or the entire surface of the third side surface portion is unnecessary as an inclined surface or a curved surface. Since the parts are simplified, it is possible to reduce the size and weight as a whole.

Since unnecessary parts have been simplified, it is possible to reduce the size and weight as a whole. Therefore, the functional component 2 is easy to handle. Further, since the case member 3 has a shape that gradually protrudes from the luminaire 1 by the third side surface portion 30b, it looks good in terms of design. Further, the functional component 2 can suppress the amount of dust accumulated on the surface by making the third side surface portion 30b an inclined surface or a curved surface. Moreover, since the functional component 2 can reduce the material cost, it can also contribute to the reduction of the manufacturing cost.

That is, by arranging the electric wire 19 and the connector 36 in the internal space of the case member 3, the internal space can be effectively utilized, and the case member 3 can be made smaller and lighter. Further, the length of the electric wire 19 can be shortened by providing the electric wire hole 30c and the connector 36 so as to face each other.

Although the present invention has been described above based on the embodiments, the present invention is not limited to the configuration of the above-described embodiments. For example, the functional component 2 shows a configuration as a motion sensor as an example, but the present invention is not limited to this. The functional component 2 may be, for example, an illuminance sensor, an emergency light unit, a wireless unit, or the like. Further, the above configuration of the support mechanism 14 is an example, and other configurations may be used as long as the first fixing member 4 can be slid and assembled. Further, although not shown in detail, the functional component 2 is provided with a mechanism for changing the height or a mechanism capable of rotating in the left-right direction between the functional component 2 and the lighting fixture 1, so that the detection range of the sensor can be increased. It may be a variable configuration.
