Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connected lighting device, and its purpose is to prevent the connected portion from becoming dark in the connected state.

In general, in connected lighting equipment in which elongated lighting equipment with straight tube fluorescent lamps are connected in the longitudinal direction and attached to the ceiling, sockets for holding the fluorescent lamps at both ends are provided at both ends of the equipment body. However, when the lamps are connected together as described above, the sockets are located between the fluorescent lamps of adjacent lighting equipment, and only this part becomes dark, the illuminance is uneven, and the appearance is unsightly.

The present invention has been developed in view of the above points, and will be explained below based on the drawings.

FIG. 1 shows an embodiment of the present invention, in which a device main body 1 has stepped portions 2 with a width of 1/2 formed at both ends at points symmetrical to each other with respect to the center of the device main body 1. Sockets 3 are provided at both ends of the device body 1, and a straight tube type fluorescent lamp 4 is arranged obliquely along the longest diagonal line of the device body 1.

The lighting equipment is used by combining the stepped portions 2 at each end and attaching them to the ceiling continuously in the longitudinal direction. When installed in a connected state like this,
Each luminaire has stepped portions 2 at both ends overlapping in the longitudinal direction, and each fluorescent lamp 4 is connected and held at its end to a socket 3 provided in the stepped portion 2.
The ends are also placed next to each other.

As described above, in the connected lighting equipment, there is no part where the fluorescent lamp 4 is not located in the longitudinal direction, and there is no dark part in the longitudinal direction, so that uniform illuminance and good appearance can be achieved.

Next, FIGS. 2 and 3 show other different embodiments of the present invention, which relate to various forms of the stepped portion 2 in the embodiment of FIG. 1.

In Fig. 2, stepped portions 2 with a width of 1/2 are formed symmetrically with respect to the longitudinal center line of the device main body 1, and when connected, they should be placed alternately in opposite directions. For example, the stepped portions 2 are combined with each other.

In FIG. 3, the ends are formed obliquely, which is included in the concept of the stepped portion 2 described above.

The present invention is constructed as described above, and has 1/2 width portions or oblique portions at both ends of the elongated device body 1 to which the straight tube fluorescent lamp 4 is connected and held by the sockets 3 at both ends. A plurality of instrument bodies 1 are attached successively in the longitudinal direction, and the stepped sections 2 of adjacent instrument bodies 1 are combined with each other. Since the socket 3 is provided, when a plurality of appliance bodies 1 are installed in succession in the longitudinal direction, the stepped portions 2 of adjacent appliance bodies 1 in the longitudinal direction overlap,
Adjacent fluorescent lamps 4 whose ends are connected and held to sockets 3 provided in the stepped portion 2 overlap, and there is no place along the longitudinal direction where no fluorescent lamp 4 is located, and there is a dark area in the longitudinal direction. It is possible to make the illuminance uniform without any problems, and it also has an excellent appearance.
