Description

Luminaire, luminaire group and method for mounting a plurality of luminaires

Technical Field

The invention relates to a luminaire, a group of luminaires and a method for mounting a plurality of luminaires.

Background

Luminaires are devices that support light sources and are devices that can be mounted on, for example, a ceiling or a wall. Fluorescent lamps, LED lamps and track lamps are known as general luminaires. Conventionally, when a lighting fixture is mounted on a ceiling or a wall, a plurality of lighting fixtures may be connected to each other by wires, or may be provided at intervals. In order to prevent various wires exposed to the outside in a case where a plurality of luminaires are connected and mounted, there is known a technique in which a connection bracket is provided between the luminaires, and the wires and the like are arranged inside the connection bracket (korean patent registration No. 10-1679656). On the other hand, in the related art, a plurality of straight tube-shaped illuminators can be directly connected to each other to conduct electricity by forming a terminal groove of a predetermined shape at one end of the illuminator and forming a terminal protrusion which can be inserted into the terminal groove at the other end of the illuminator, which is well known.

However, the conventional luminaire connection bracket requires a wiring work to connect between a plurality of luminaires, and a mounting work of the connection bracket to block exposure of wires and the like, unnecessarily increasing a work time. Also, the conventional illuminators having the terminal protrusions and the terminal grooves may be directly connected to each other only at a fixed angle, thus increasing the work of individual wiring, and exposing the wiring to the outside for the work of connecting a plurality of illuminators at a desired angle.

The connection socket for the illuminator includes socket connection parts 31 and 91 protruding outward or recessed inward to be connected to other external sockets. For example, an additional connection socket for a luminaire provided to a user may be provided, or a connection socket for a luminaire provided to a manufacturer to manufacture a luminaire or a group of luminaires may be provided.

Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. In the drawings, the same or corresponding components are assigned the same reference numerals. In addition, in the description of the following embodiments, a repeated description of the same or corresponding components may be omitted. However, even if the description of the component is omitted, it is not meant that the component is not included in any embodiment.

The connection sockets 30,30 "', 30" ", 90' are rotatably or detachably arranged on the frame 10, so that the direction F can be changed. Referring to fig. 1 to 42, the connection sockets 30,30 "', 30" "of the luminaires 1,1', 1", 1 "', 1" ", 2,3,4, 5', 6' according to the first to sixth embodiments may be rotatably provided on the frame 10 about a predetermined rotation axis, so that the orientation F of the socket connection part 31 may be changed based on the frame 10. As shown in fig. 43 to 61, the connection sockets 90,90 'of the illuminators 7, 8, 8' according to the seventh and eighth embodiments are detachably provided on the frame 10, so that the orientation F of the socket connection part 91 can be changed based on the frame 10.

Fig. 1 is a perspective view showing a luminaire 1 according to a first embodiment of the present disclosure and another external luminaire M. Fig. 2 is a perspective view showing a state in which the orientation F of the connection socket 30 of the luminaire 1 of fig. 1 is changed.

Referring to fig. 1 and 2, the illuminator 1 may be formed to be elongated in the longitudinal directions Y1, Y2. The luminaire 1 may have a rectangular parallelepiped shape as a whole. The light source L may be arranged in the luminaire 1 to emit light downward. The upper surface of the luminaire 1 is attached to an external attachment surface (e.g., a top surface or a wall surface) so that the luminaire 1 can be mounted. The luminaire 1 comprises a frame 10 and a connection socket 30 arranged on the frame 10.

The connection socket 30 is arranged to be rotatable with respect to the frame 10 about a predetermined rotation axis. The "axis of rotation" as used in this disclosure is an imaginary axis and does not refer to an actual part of the apparatus. In order to provide the function of the predetermined rotation axis, a shaft provided on the rotation axis may be provided, and a groove or a hole in which a protrusion protruding along the rotation axis and the protrusion are rotatably engaged may be formed.

The frame 10 may be elongated in the longitudinal directions Y1 and Y2. The light source L may be disposed in the frame 10 along the longitudinal directions Y1 and Y2 of the frame. The connection socket 30 may be provided at one end of the frame 10 in the longitudinal direction Y1, Y2. In this embodiment, the connection sockets 30 are arranged at the ends of the frame 10 in the first longitudinal direction Y1.

The connection socket 30 may be disposed closer to the upper surface than the lower surface of the frame 10. In this way, while it is effectively ensured that the light source L can be arranged in the space of the lower portion of the luminaire 1, it is easy to ensure the arrangement space for the connection socket 30 in the upper portion of the luminaire 1. The connection socket 30 may be provided above a light source arrangement space 110t in the frame 10, which will be described later.

The rotation axis of the connection socket 30 may extend in a direction orthogonal to the direction in which the socket connection part 31 protrudes or is recessed. In this way, the orientation F of the connection jack 30 can be effectively changed.

The axis of rotation of the connection socket 30 may extend in a direction orthogonal to the longitudinal directions Y1, Y2. This makes it possible to efficiently extend and connect a plurality of illuminators 1 and to easily change the extending direction. For example, there may be a vertical direction (U, D) or a width direction (X1, X2) in a direction crossing the longitudinal direction Y1, Y2, but the present disclosure is not limited thereto. In this embodiment, the axis of rotation extends in a vertical direction.

In an embodiment in which the rotation axis extends in the vertical direction, the height of the uppermost surface of the connection socket 30 may be lower than the height of the uppermost surface of the frame 10, or equal to the height of the uppermost surface of the frame 10. In this way, the orientation F of the connection socket 30 can be smoothly changed without being disturbed by an external mounting surface (e.g., a top surface or a wall surface) on which the luminaire is mounted. The height of the top surface of the connection socket 30 of the luminaires 1,1',1 "", of some embodiments, is lower than the height of the top surface of the frame 10. The top surface of the connection socket 30 of the luminaire 1 ", 1" ', 2,3,4, 5', 6', 7, 8' of other embodiments described later is the same height as the top of the frame 10.

The respective socket 40 may include a respective socket portion 41 protruding outward or recessed inward to couple to another external socket. The respective socket 40 includes a corresponding terminal (not shown) configured to electrically contact a terminal disposed in the external socket. The corresponding terminals are formed of a conductive material such as metal. The respective terminals may be arranged inside the respective socket connection parts 41. The corresponding terminal may have an outwardly protruding or inwardly recessed shape so as to engage with a terminal of another external receptacle. In this embodiment, the corresponding terminals have an outwardly protruding shape.

In fig. 1 and 2, a respective socket 40 is shown corresponding to another external illuminator M, which can be understood as an illuminator having the same shape as the illuminator 1. That is, the connection sockets 30 are provided at one end of the longitudinal directions Y1, Y2 of the frame 10, and the corresponding sockets 40 are provided at the other end of the longitudinal directions Y1, Y2 of the frame 10. In this embodiment, the respective sockets 40 are provided at the ends of the frame 10 in the second longitudinal direction Y2.
