Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (8 Fields of Industrial Application) The present invention relates to a guide light fixture, and more particularly to a thinner fixture.

(Prior Art) As a guide light fixture in which a translucent display panel is provided opposite to a lamp, for example, a guide light fixture described in Japanese Utility Model Application Publication No. 60-76386 is widely known. ing.

For example, this conventional guide light fixture is made of a light-transmitting synthetic resin that faces a straight fluorescent lamp installed inside the fixture body.
A structure was adopted in which an illuminated display panel was provided, and lighting components such as a ballast were provided within the device body. In this conventional Pi guide light fixture, the distance between the lamp and the display panel is widened to prevent the appearance of a lamp image or uneven brightness, and the ballast installed inside the fixture body However, if lighting parts such as batteries do not appear in the shadows, the thickness of the fixture becomes thicker, resulting in poor marketability.

This kind of guide light equipment does not need to stand out very much during normal times, but rather it is easy to disturb the indoor interior decoration, so there is a demand for miniaturization. On the other hand, in guide light equipment, the minimum size of the display surface is stipulated by law, and miniaturization involves reducing the size in the width direction. However, if the conventional guide light equipment mentioned above is made thinner as it is, the space between the lamp and the display panel will be narrowed as described above, a lamp image will appear, uneven brightness will occur, and furthermore, the ballast, battery, etc. A problem arises in which lighting parts such as these appear as shadows on the display panel.

In addition, the display panels used in guide lights must be exposed to a flame directly and the time required for them to ignite is longer than the specified time according to the Japan Lighting Industry Association Technical Standards (JIL5502).
- the use of such flame-retardant materials is prescribed; Therefore, the display panel of the guide light is generally made of a translucent board made of flame-retardant vinyl chloride resin.

(Problems to be Solved by the Invention) If the conventional guide light equipment described above is simply made thinner, a lamp image will appear on the display panel, uneven brightness will occur, and furthermore, the ballast placed inside the equipment body, Lighting parts such as batteries appear as shadows on the display panel, and since lighting parts such as ballasts are built into the main body of the device, there are problems with assembly work, and inspection and maintenance of lighting components also occur inside the main body of the device. In addition, the PVC resin display panels used in conventional guide light equipment have low heat resistance and yellowing resistance, even though they are flame retardant.
Due to the demand for thinner equipment, when trying to make the lamp and display panel close together, the panel becomes yellow due to the ultraviolet 11 and heat emitted from the lamp, or the heat generated by the lighting components such as the ballast. There are problems such as heat deformation, heat deformation, etc., making it impossible to function as a display board, and it is currently technically impossible to improve the heat resistance and yellowing resistance of vinyl chloride resin. are doing.

In addition, it is known that acrylic resin is used as a transparent synthetic resin material for the display panel of this type of guide light equipment, but although acrylic resin has excellent heat resistance and yellowing resistance, it is flame retardant. However, using acrylic resin panels for guide light fixtures is problematic due to the above-mentioned standards.

In addition, acrylic styrene resin, polycarbonate resin, sudirol resin, and As resin are known as light-transmitting synthetic resin materials, but all of these resins have problems with poor yellowing resistance and flame retardancy. There is.

The present invention has been developed in view of the above problems, and eliminates the appearance of lamp images on the display panel and uneven brightness, and furthermore, almost all lighting components such as ballasts and batteries cast shadows on the display panel. The display panel facing the straight tube lamp has flame retardancy, heat resistance, and yellowing resistance, allowing the straight tube lamp to be placed close to the display panel, and also improving workability in assembling lighting parts. To provide a guide light fixture that can improve safety, be easily inspected and repaired, ensure safety, and be formed into a thin shape.

[Structure of the invention]

It is characterized in that it is disposed approximately at the center, and lighting components including the ballast are attached to both ends of the appliance main body facing outward.

(For 4) The guide light fixture of the present invention has a display panel having a light diffusive pattern, so that even if the distance between the lamp and the display panel is small, the image of the lamp can be displayed on the display panel.
There is no unevenness in brightness, and lighting components such as ballasts installed inside the device body do not appear as shadows on the display panel, allowing the entire device to be made thinner, and lighting components such as ballasts installed inside the device body. Since the parts are attached outward at both ends of the 5-piece body, it is easy to assemble the lighting parts, inspection and repair can be done from outside the body of the body, and the display panel is made of flame-retardant acrylic resin. Therefore, even if the display panel is placed close to the lamp and made thin, the display panel will not undergo thermal deformation or yellowing due to ultraviolet rays and heat from the lamp or heat dissipation from lighting components such as ballasts. , has durability, ensures safety, displays evenly on both sides, especially in devices with display panels on both sides, and can be used for a long time with even effects from lamps on the display panel.
