Description

[Detailed explanation of the idea] The present invention relates to a fluorescent lighting device.

Some types of fluorescent lighting equipment use glow lamps and others do not, but in general, those that use glow lamps have holes in the reflector plate and the tips of the glow lamps are inserted in order to facilitate replacement. Protruding outward, however, providing holes in the reflective plate, which is a distribution control member, is difficult to process, but it also causes a decrease in lighting efficiency.

In addition, this hole is not necessary in a device that does not use a glow lamp, and even if the device is of the same type in appearance, it is necessary to manufacture it as a separate part.

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

Figures 1 and 2 show an embodiment of the present invention, in which 1 is a device body with a lamp socket 2 and a glow socket 3 attached, and a hole corresponding to the glow socket 3 is provided in the center of the bottom surface, and a glow lamp 4 is provided. It can be attached with the tip protruding downward.

Reference numeral 5 denotes a substantially flat reflector plate attached to the lower surface of the appliance main body 1, through which the glow lamp 4 is inserted.

6 is an auxiliary reflector, and a curved piece 8 covers the outside of the lamp 7;
a substantially triangular prism-shaped intermediate reflective piece 9 located between the lamps;
An insertion hole 11 for the glow lamp 4 is provided on the back surface of the intermediate reflecting piece 9, which is integrally formed with the end plate 10 that shoots both ends of the reflecting piece 9.

A frame 12 is detachably attached to the lower surface of the main body by a V-shaped spring 13, and the auxiliary reflecting plate 6 is placed on this frame 12 and attached to the main body.

In the structure as described above, the glow lamp 4 passes through the reflector plate 5 and has its tip housed within the intermediate reflector piece 9, so that the glow lamp 4 is not visible from the outside during normal use, and the glow lamp 4 is not visible from the outside. The main body can also be used as a device without using a reflector, and the efficiency of the reflector will not be hindered.

When replacing the glow lamp 4, the reflector 6 is removed together with the frame 12.
can be easily removed.

The present invention is structured as described above, and the glow lamp is covered with a removable auxiliary reflector, so that the light control function is not hindered, and each component can be used as is even in the case of an appliance that does not use glow.

Furthermore, when replacing the glow lamp, only the auxiliary reflector needs to be attached and removed, and the main body of the device is protected by being covered with the reflector, so there is no risk of the worker accidentally touching the internal live parts or the like and getting an electric shock.
