[Detailed description of the device]

[0001]

[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device having a straight tube lamp, and more particularly to a lighting device having a socket cover for covering a socket.

[0002]

[Prior art]

 For example, as shown in FIG. 5, a lighting fixture used for hand lighting in a kitchen has sockets 2 arranged at both ends on the lower surface side of a main body 1 whose lower surface is a reflection plate 10 via socket bases 20, A straight tube lamp 3 is arranged between the sockets 2, and a socket cover 4 for covering the socket 2 is attached to the reflection plate 10.

[0003]

[Problems to be solved by the device]

 In the above lighting equipment, the socket 2 is attached to the main body 1 via the socket base 20, but due to variations in the mounting position of the socket base 20 and variations in the dimensions of the socket base 20, the straight tube lamp 3 The distance between the pair of sockets 2, 2 for holding both ends of the straight pipe 3 may not be an accurate value and sometimes becomes a little large, and the holding of the straight pipe lamp 3 may become unstable.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a lighting fixture capable of maintaining a pitch between sockets at a regular value.

[0005]

[Means for Solving the Problems]

 Therefore, the present invention is directed to a luminaire having a straight tube lamp between the sockets arranged at both ends and having a socket cover for covering the socket, and the inner surface of the socket cover attached to the body of the luminaire. In addition, a pressing portion for pressing the outer surface of the socket in the axial direction of the straight tube lamp is provided.

[0006]

[Action]

 According to the present invention, the socket cover that covers the socket restricts the position of the socket by pressing the outer surface of the socket with the pressing portion.

[0007]

【Example】

 The present invention will be described in detail below with reference to the illustrated embodiment. In FIGS. 1 to 3, the main body 1 is one in which sockets 2 and 2 are arranged on the lower surfaces of both ends via socket bases 20 and 20, respectively. A main body cover 11 and a reflection plate 10 are attached to the lower surface side. In the figure, reference numeral 12 is an inverter block for lighting harmonics. The pair of sockets 2 and 2 in which the straight tube lamp 3 is arranged are covered with socket covers 4 and 4 which are attached to the main body 1 via the attachment fittings 15 and the attachment springs 5, respectively. In addition, the illustrated example is a lighting fixture including two straight tube lamps 3 and 3, and the two sockets 2 and 2 at one end of the main body 1 are covered with a single half-dome-shaped socket cover 4. ing .

As shown in FIG. 4, the mounting bracket 15 has locking holes 16 and 16 on the lower end side thereof, and the mounting spring 5 fixed to the socket cover 4 with a screw or the like has a locking projection 5 on the upper end. It is formed as one having 0, and by inserting and locking the locking projection 50 at the tip of the mounting spring 5 into the locking hole 16 of the mounting metal fitting 15, the socket cover 4 can be attached to the main body 1. Has been done. At this time, the ribs 40 formed on the edge of the socket cover 4 approximately half the circumference are fitted into the grooves 17 formed in the body cover 10, so that the ribs 40 can be removed from between the end portion of the body cover 10 and the socket cover 4. The light of the straight tube lamp 3 is prevented from leaking laterally in the longitudinal direction of the luminaire.

Further, each socket cover 4 is provided with a pressing rib 41 on its inner surface which comes into contact with the outer surface of the socket 2 and presses the socket 2 in the axial direction of the straight tube lamp 3. For this reason, when the socket cover 3 is attached to the body 1, even if the distance between the pair of sockets 2 and 2 to which both ends of the straight tube lamp 3 are attached is slightly larger than the original value, it is pressed by the pressing rib 41. As a result, the original value is maintained, and the holding of the straight tube lamp 3 does not become unstable.

[0010]

[Effect of device]

 As described above, according to the present invention, the socket cover that covers the socket restricts the position of the socket by pressing the outer surface of the socket with the pressing portion. The holding of the tube lamp does not become unstable, and the presence of the above-mentioned pressing portion serves as a mounting guide for the socket cover when the socket cover is mounted on the main body. It will be easier.
