DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide lamp apparatus using a fluorescent lamp.

[0002]

2. Description of the Related Art Conventionally, a structure described in Japanese Utility Model Application Laid-Open No. Sho 61-126507 is known as a guide light device.

In this guide light fixture, a translucent display panel is disposed opposite to a straight tube-type fluorescent lamp mounted in the fixture body, and a lamp lighting component such as a ballast is provided in the fixture body. Arranged structure is adopted.

The distance between the fluorescent lamp and the display panel is widened so that a lamp image does not appear or luminance unevenness does not occur, and a ballast of the guide lamp body does not appear as a shadow. , The thickness of the equipment is increasing.

[0005] By the way, the guide light device usually does not need to be noticeable at all, but rather tends to impair the interior decoration and is required to be downsized. However, since the minimum size of the display surface of the guide light device is regulated by laws and regulations, the miniaturization mainly reduces the size in the thickness direction to reduce the thickness of the entire device.

[0006]

However, in the conventional guide light fixture, if the guide light fixture is simply thinned as it is, the fluorescent lamp and the display panel come close to each other, and the ultraviolet light included in the light emitted from the fluorescent lamp causes the fluorescent lamp to approach the display panel. There are problems of yellowing and thermal deformation due to the heat of the fluorescent lamp.

In addition, when the guide light device is simply made thin as it is, a part of the lamp lighting parts such as the ballast is disposed to face the effective display surface of the display panel. Parts appear as shadows on the display panel,
The appearance of the display panel is impaired.

The present invention solves the above problems,
Provide an induction lamp device that is thin and can be formed with a small height in the height direction, yet is less susceptible to the effects of ultraviolet light and heat from the fluorescent lamp and less likely to cause shadows of lamp lighting components to appear on the display panel. The purpose is to do.

[0009]

According to a first aspect of the present invention, there is provided a guide lamp apparatus comprising: a fluorescent lamp; and at least a front opening and storage pockets disposed on both sides of the opening except the opening. A light-transmitting flame-retardant material disposed in an opening of the light-emitting device main body; and a lamp lighting-related component including a ballast for lighting a fluorescent lamp, wherein the effective display surface is substantially provided. And a lamp lighting component that is stored at least largely in the storage pocket on the outside.

By arranging a light-transmissive flame-retardant material in the opening of the fixture body, the fluorescent lamp can irradiate the fluorescent lamp even if the fixture body or the display panel provided in the opening is brought close to the fluorescent lamp. The device main body is made thinner and smaller in volume without yellowing due to ultraviolet rays contained in the light to be emitted or being thermally deformed by the heat of the fluorescent lamp. Visibility can be maintained without deterioration due to a flame from the outside in a fire or the like.

In addition, since at least a large part of the lamp lighting components is dispersed and stored in the storage pockets on both sides of the device main body substantially outside the effective display surface, the device is thin and has a small dimension in the height direction. The main body is formed, and the appearance of the shadow of the lamp lighting component on the effective display surface is reduced. Furthermore, since at least most of the lamp lighting parts such as ballasts are stored in the storage pockets on both sides of the fixture main body, the lamp lighting parts are easy to unitize, wiring is reduced, and assembly work is reduced. Easier,
Inspection work is also easy.

Note that the effective display surface is a portion on which a display indicating the evacuation direction is formed and which emits light by the transmitted light of the fluorescent lamp. The term “substantially outside” refers to a position where almost no shadow is projected on the effective display surface, and includes the rear of the periphery of the effective display surface.

According to a second aspect of the present invention, in the first aspect, the flame retardant also serves as a display panel and is disposed in the opening.

Since the flame-retardant material also serves as the display panel and is disposed in the opening, even if the fluorescent lamp and the display panel are brought close to or in contact with each other, the display panel can emit ultraviolet light contained in the light emitted from the fluorescent lamp. Yellowing by
There is no thermal deformation due to the heat of the fluorescent lamp, and the apparatus body is made thinner and smaller in volume.
