Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-flash fluorescent lamp device including a multi-flash unit.

[Prior Art] A method of forming a fluorescent lamp apparatus in which accessories such as a louver and a plastic cover are arranged below a fluorescent lamp and a fluorescent lamp apparatus without such accessories by a common apparatus main body has become widespread.

Specifically, a socket base that can move up and down is provided at both inner ends of the common appliance body that is open-bottomed. If the socket base is set at a high position and the fluorescent lamp is placed at a high place, a space for placing accessories thereunder is secured. When accessories are not required, the fluorescent lamp is arranged at a low place to obtain desired light distribution characteristics.

If accessories are added, it will be dark. In order to compensate for the shortage, a method of appropriately increasing the number of fluorescent lamps has been developed. In this case, a separately-provided multi-flash unit is added to make a multi-flash fluorescent lamp device.

In a conventional multi-lamp type fluorescent lamp device, a multi-lamp unit is fixed between socket stands at both ends of the device body. Then, the sub lamp socket on the side of the lighting unit is fixed to the socket base on the fixture body side.

Multi-flash fluorescent lamps are high-power fluorescent lamps. In general, appropriate accessories are used together, but it is possible to select whether or not to use them together. If you have accessories, you can get low-bright, high-quality light. If accessories are omitted, it becomes a very bright instrument.

[Problems to be Solved by the Invention] In a conventional multi-lamp type fluorescent lamp fixture, since the multi-lamp unit is passed between the socket tables and fixed, the height of the socket table cannot be adjusted as it is. Since the entire load of the socket for a flashlight is applied to the socket base, when the height of the socket base needs to be adjusted, it is necessary to temporarily remove the flashlight unit, which is troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to enable the height adjustment of a socket base to be performed while a light-up unit is mounted.

[Means for Solving the Problems] A lighting unit of the invention according to claim 1 is a lighting plate that is shorter than the fixture body, a sub-ballast fixed to the lighting plate, and a sub-lead. Includes a pair of secondary lamp sockets connected via wires.

The lighting plate is mounted at the center of the inside of the fixture body at a distance from each socket base. On the other hand, each sub-lead is extended in the longitudinal direction of the fixture main body, and each sub-lamp socket ahead is mounted on each socket base.

In the invention corresponding to claim 2, a required pair of reinforcing plates are used, and the lighting plate is fixed to the inner central portion of the fixture body via the reinforcing plates.

[Operation] The lighting unit of the present invention is shorter than the fixture body and does not reach the socket bases at both ends of the fixture body. To compensate for the lack of length, extend each sub-lead in the longitudinal direction of the instrument body,
Each sub lamp socket beyond that is mounted on each socket base.

Electrical components other than the auxiliary lamp socket, such as the auxiliary ballast, are mounted on a short-sized light increasing plate. The lighting plate is mounted in the center of the inside of the fixture body, but this is irrelevant to the height adjustment of the socket base and does not need to be removed at the time of height adjustment.

[Embodiment] An embodiment of the present invention shown in FIGS. 1 and 2 will be described. The device of the present embodiment is a long device body 10 with an open bottom.
Is provided. The apparatus includes a socket base (12) mounted on both inner ends of the device body (10) so as to be vertically movable. Each socket base 12
It has a main lamp socket 13 mounted on 12. Further, a lighting unit 30 is provided.

The flashlight unit 30 includes a flashlight plate 31 shorter than the fixture body 10 and a sub-ballast 33 fixed to the flashlight plate 31.
And a pair of sub lamp sockets 36 connected via sub lead wires 35. Numeral 34 denotes a wiring terminal block fixed to the light increasing plate 31.

A multiplying light plate 31 is attached to the center of the inside of the fixture body 10 at a distance from the socket bases 12. Each sub-lead 35
35 is extended in the longitudinal direction of the fixture body 10, and the sub lamp sockets 36, 36 ahead of it are mounted on the socket bases 12, 12, respectively. First
14 in the figure is the auxiliary lamp socket prepared in advance on the socket base 13.
Notch for mounting 36.

Reference numeral 20 denotes a pair of reinforcing plates for mounting the additional lamp plate 31, which also serves as reinforcement of the apparatus main body 10. Each reinforcing plate 20 is fixed inside the instrument main body 10 at a predetermined interval, and reinforces the top surface and side surfaces of the instrument main body 10. The device main body 10 and the reinforcing plate 30 are connected to each other by means such as spot welding and screwing so that the mounting holes 11 and 21 of the two coincide with each other. Further, the reinforcing plate 20 and the tool body 10 are fastened together by bolts (not shown) for mounting the tool body 10 that penetrate through the mounting holes 11 and 21. Both end portions 32 of the plate for increasing light 31 are fixed to the mounting holes 22 of each reinforcing plate 20. 39
Are mounting screws for that.

Most of the load of the lighting unit 30 in this embodiment is directly borne by the bolts for mounting the device main body 10 via the reinforcing plate 1 and the load on the device main body 10 is reduced by that much. Deformation due to load is minimal.

The load of the lighting unit 30 is not applied to the socket base 12. Although the load of the sub lamp socket 36 is applied, the influence is small as a matter of course, so that the socket table 12 can be freely moved up and down even after the additional lamp unit 30 is mounted.

FIG. 3 is an embodiment showing a multi-flash unit 300 for two lights. The multi-flash unit 300 includes two sets of four sub lamp sockets 36 and a corresponding number of sub lead wires 35. The other points are similar to the multi-flash unit 30 in FIG. 1, and therefore, the part numbers in FIG. Although the illustration of the appliance main body into which the multiplying light unit 300 is to be incorporated is omitted, it is similar to the appliance main body 10 of FIG.

[Effects of the Invention] In the present invention, the light-enhancing plate of the light-enhancing unit is made shorter than the fixture main body, and the light-enhancement plate is attached to the inner central portion of the fixture main body at a distance from each socket base. Then, each sub-lead was extended in the longitudinal direction of the fixture body, and each sub-lamp socket ahead was attached to each socket base, so that the height of the socket base could be adjusted even with the unit for increasing light installed. Easy to do.
