Abstract

PURPOSE:To prevent connectively installed lighting fixtures from being darkened at the end portions of lamp. CONSTITUTION:A socket mounting portion 8 the width of which is roughly half of that of an end portion connecting member 11 is formed integrally with one end portion of a reflecting plate 1. The extension side surface portion 13 of the end portion connecting member 11 which is so formed as to extend from the bottom surface portion 12 of the member 11 is connected to the other end portion of one side plate portion 4 of the reflecting plate. A socket mounting member 17 is opposite to one side face of the socket mounting portion 8 of the reflecting plate 1 which is located adjacent a socket mounting surface portion 18, and has an inside surface portion 19 affixed to the bottom surface portion 12 of the end portion connecting member 11 and an outside surface portion 21 affixed to the extension side surface portion 13 of the end portion connecting member 11. Lamp sockets 26, 27 are installed opposite to the socket mounting portion 8 and the socket mounting portion 17, respectively, and have a straight bulb lamp 24 mounted along a rough diagonal of their upper surface portion 2. The bulb end portions of the lamp are displaced to the center side and made to overlap each other. No part is darkened and uniform illuminance can be obtained. The lighting fitting is structurally strengthened and defective contact will not occur.

[Detailed description of the invention]

[Object of the invention]

0002

[Industrial Application Field] The present invention relates to a connected lighting device,
To prevent the illuminance between the ends of the fixtures and at the ends of the fixtures from being reduced due to the lamp socket when the fixtures equipped with tubular lamps are connected, and to relate to a fixture particularly suitable for indirect lighting.

0003

2. Description of the Related Art Conventional lighting equipment of this type has, for example, a step-shaped portion protruding at a diagonal position in which the side surfaces of the ends of the fixture body adjacent to both ends of the fixture body face each other. At the end of the section, a lamp socket for mounting a straight tube lamp diagonally along the diagonal line of the fixture is installed, and the stepped sections are combined with each other to connect the fixtures in a straight line. A structure is known in which the spaces between the two do not become dark. The stepped portion of this appliance is integrally formed at both ends of the reflector, and a socket mounting hole is punched out from the stepped portion, and a lamp socket is fixed in the socket mounting hole.

0004

[Problems to be Solved by the Invention] In the conventional structure described above, the lamp socket is attached to a stepped part formed at the end of the elongated reflector, so the straight tube lamp is press-fitted to the lamp socket along the diagonal line. When mounted and held, the stepped portion of the reflector plate tends to twist due to the pressing force applied outward to both lamp sockets.
This twisting of the reflector tends to cause poor contact between the lamp socket and the terminal pins of the lamp, resulting in problems such as a risk of shortening the life of the lamp.

The present invention has been made in view of the above-mentioned problems, and includes a structure in which the mounting portion of the socket mounting portion is designed to prevent the connecting portion of an adjacent device from being darkened by the tube end of the tube lamp. To provide a connected lighting fixture which is strengthened to prevent twisting and poor contact between a terminal pin of a lamp and a lamp socket.

[Configuration of the invention]

[0007]

[Means for Solving the Problems] The connected lighting device of the present invention includes an upper plate portion and side plate portions formed by bending downward from both side edges along the length direction of the upper plate portion, and has one end. A socket mounting portion having an extended side plate portion extending from the one side plate portion and an extended top plate portion extending from the upper plate portion and having a widthwise dimension of about half is integrated into the portion. A substantially L-shaped reflector comprising a formed reflector plate and an extended side face portion having a flat bottom face and an extended side face portion that is bent upward from the bottom face portion and connected to the other end of the other side plate portion of the reflector. an end connecting member, a socket mounting surface part that is connected to the other end of the upper plate part, and a lower part of the socket mounting surface part that is bent downward from one side of the socket mounting surface part and attached to the bottom part of the end connecting member. a substantially U-shaped socket mounting member having an inner side surface portion to be fixed and an outer side surface portion overlapping and fixed to the extension side surface portion of the end connecting member; and an extension of the socket mounting portion of the reflector plate. The lamp socket is provided with a lamp socket which is mounted opposite to the end of the top surface and the end of the mounting surface of the socket mounting member, respectively, and into which a tubular lamp is mounted along a substantially diagonal line of the top surface.

[0008]

[Operation] In the connected lighting fixture of the present invention, the socket mounting portion protruding from one end of the reflector is placed on the bottom of the end connecting member attached to the other end of the adjacent reflector. , the inner side surface of the socket attachment member attached to the end connecting member of the adjacent reflector plate is arranged to face the other side surface of the socket attachment part, and the extended top plate part is formed into an extension of the upper plate part of the adjacent reflector plate. By positioning each adjacent reflector plate, each adjacent reflector plate is arranged on a straight line. Since the lamp sockets are installed facing each other at the end of the extended top plate part of the socket mounting part of each reflector plate and the end of the mounting surface part of the socket mounting member, the tube end of the straight tube lamp is The tube ends of adjacent straight tube lamps overlap toward the center, and there are no darkened areas, providing uniform illuminance. Each reflecting plate has an outer side surface portion of the socket mounting member fixed to the inner side surface portion of the bottom surface portion of the end portion connecting member attached to the extended side surface portion of the end connecting member connected to the other end of the other side plate portion. Due to the overlapping and fixing, the socket mounting member is structurally strengthened, and when a straight tube lamp is attached to the lamp socket, poor contact between the terminal pin of the lamp and the lamp socket will not occur.

By locating the reflecting plates 1 on an extension of the plate portion 2, the adjacent reflecting plates 1 are arranged on a straight line. Since the lamp sockets 26 and 27 are mounted facing each other at the end of the extended top plate part 6 of the socket mounting part 8 of each reflector plate 1 and the end of the mounting surface part 18 of the socket mounting member 17, The tube ends of the tube lamps 24, 24 overlap closer to the center than the tube ends of the adjacent straight tube lamps 24, 24, so that there is no darkened portion and uniform illuminance is obtained.

Each reflecting plate 1 is connected to the extended side surface 13 of the end connecting member 11 connected to the other end of the other side plate 4.
Since the outer side surface portion 21 of the socket mounting member 17 fixed to the inner side surface portion 19 is overlapped and fixed to the bottom surface portion 12 of the end connecting member 11, the socket mounting member 17 is structurally strengthened, and the lamp sockets 26, 27 are When the straight tube lamp 24 is mounted, there is no deformation such as twisting due to the pressing force applied to the lamp sockets 26, 27 at both ends, and no contact failure occurs between the terminal pins of the lamp 24 and the lamp sockets 26, 27.

Note that an electric wire is connected to one terminal block 29 of the plurality of reflecting plates 1 arranged in series, and the terminal blocks 29 are sequentially connected by feeding wiring within the capacity range of this terminal block 29. Since this feed wiring can be performed between the connecting parts without removing the reflector 1, workability in constructing the instrument can be improved.
