Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a lighting device that can be multiplied by using a sub-lighting device, and in particular, a lighting device that allows a louver, a cover, etc. to be attached to the bottom opening. The invention relates to lighting equipment.

Conventional technology A lighting fixture that can be multiplied by sub-lighting fixtures and has a louver attached to the bottom surface of the fixture body is, for example, the type described in JP-A No. 63-269404. There is something.

This type of lighting equipment has a structure in which the louver is attached to the equipment body with an opening at the bottom, and a socket holder is formed at both ends of the louver to allow the socket base to be selectively mounted in the upper position or the lower position. Both ends of the auxiliary lighting equipment are fixed to these sockets.

In other words, if a louver or cover is not used, the socket stand should be placed in a lower position to improve lighting efficiency, and if a louver or cover is installed, the socket base should be positioned in a lower position to ensure space for the louver or cover. The socket stand is placed in the upper position. In each case, when it is necessary to add more lights, a sub-lighting device is hung and fixed to each socket stand.

Problems to be Solved by the Invention Since the socket base is attached to the device body selectively in the vertical position, a protrusion is formed on the inner surface of the device body, and the socket base is moved horizontally to engage with the aforementioned protrusion. This is done by doing this.

Therefore, when no more lights are being added, the socket stands at both ends are independent, making it easy to select the upper and lower positions. That is, the socket base can be moved freely in the horizontal direction. However, if a sub-light fixture is installed to increase the number of lights, the socket mounts at both ends are integrated by the sub-light fixture, which allows the socket base to be moved in the horizontal direction. I can't. Therefore, when increasing the number of lights, the socket base cannot be raised or lowered unless the sub-lighting equipment is removed from the socket base. Therefore, there is a problem in that the operation for selecting the vertical position of the socket base is troublesome and time-consuming.

Means for Solving the Problem A device body with an opening on the bottom surface is provided with socket holders formed at both ends to selectively hold a socket base to which a socket for holding a straight tube fluorescent lamp is attached in an upper position and a lower position. established,
Reinforcing metal fittings are fixedly attached to the inner surface of the fixture main body at predetermined intervals, and the main body of the sub-lighting device, which holds the ballast and has a socket connected by a flexible cord, is attached to these reinforcing metal fittings. Attachment: The socket of the sub-lighting device was attached to the socket stand.

The main body of the secondary lighting fixture is attached to a reinforcing metal fitting fixed to the main body of the fixture, and the socket of the secondary lighting fixture is connected to the main body via a flexible cord. It is possible to freely select the vertical position of the socket base with the fixture attached, and thereby the vertical position of the fluorescent lamp can be easily set when attaching and detaching the louver, cover, etc.

Example An embodiment of the present invention will be described based on the drawings.

First, a rectangular parallelepiped-shaped instrument body 1 with an open bottom is provided, and three-step holding protrusions 3 protruding inward are punched out on the inner surfaces 2 at both ends of the instrument body 1, and a socket holding portion 4 is formed.
is formed in two stages. Furthermore, a pair of reinforcing metal fittings 5 are fixedly attached inside the instrument main body l.

These reinforcing metal fittings 5 are formed with a hook-shaped attachment portion 6 and a holding slit 7.

Next, a socket stand 8 is provided, and this socket stand 8 is formed with an insertion part 9 that is inserted into the lower or upper position of the socket holding part 4 from the horizontal direction. A locking portion 10 is formed at the tip of each of these insertion portions 9 to prevent the insertion portion from being removed. Further, the socket stand 8 is formed with a socket hole 12 for holding two sockets 11 and a sub-socket hole 13 for attaching an auxiliary socket to be described later. Further, the socket base 8 is formed with a reflection plate mounting screw portion (4), and a reflection plate 26 is attached to it by a mounting screw (not shown).

Next, a sub-light fixture 15 is provided. The sub-lighting device 15 includes a main body 18 that holds a ballast 16 and a terminal block 17, and a sub-socket 20 drawn out from the main body 18 by a flexible cord 19. At the end of the main body part 18, a mounting screw 21 which is bent in the vertical direction and inserted into the mounting part 6 comes into contact with the mounting tongue piece 22 and the lower edge of the auxiliary metal fitting 5. One side is formed with a pair of protrusions 23 to be inserted into the holding slit 7.

Next, a cover 25 supported by a frame 24 is attached to the lower opening of the instrument main body 1, if necessary. Although a description of the mounting structure of the cover 25 will be omitted, it is detachably mounted to the lower opening of the instrument main body 1.

In such a configuration, the one shown in FIG. 5 is such that two fluorescent lamps are attached without attaching the cover 25 to the appliance main body 1 and without adding more lights. In this case, in order to improve lighting efficiency, the socket stand 8 is positioned below the socket holding part 4, and the fluorescent lamp is positioned close to the lower opening.

The state shown in Figure 6 is when the number of lights is increased in this state.
A sub-light fixture 15 is attached. That is, in order to change from the two-pair state shown in FIG. 5 to the state shown in FIG.
