[Structure] In a night light in which a transparent light bulb 1 connected to an automatic blinking circuit is housed in a case 14 having a transparent light scattering plate 10 as a front panel and always attached to an indoor outlet, a rear plate 13 of the case stores light. A luminescent material 8 is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an emergency lighting device that emits light without relying on electric energy during an emergency power failure of a night light or a dark place indicator light.

[0002]

[Prior art]

 Conventionally, emergency lighting fixtures that have been provided for home use are equipped with a dry battery for charging that is always connected to a commercial power source and a power failure detection switching circuit so that the lamp is turned on only during a power failure. It is expensive regardless of whether it is present or not.

[0003]

[Problems to be solved]

 This plan uses the fact that the night lights are always lit at night. It stores the light energy of the night lights that automatically blinks small lamps of 10 W or 5 W or less, and at the same time as blackouts, this stored energy is used for evacuation. To provide fluorescent light for a sufficient period of time, providing a device that can be safely used by any number of people without any preparatory operation in case of a power outage and can expect a reliable effect in an emergency It is a thing.

[Means for solving]

 This product consists of an automatic blinking circuit that turns on and off according to the external illuminance, a transparent lamp connected to it, and a cover case that covers the lamp. The cover case is made of transparent synthetic resin and is the outer peripheral surface of the cover or the case. A phosphorescent material is provided on the back surface of the. Generally, night lights use an opaque case to soften the light or prevent the internal light source from being directly visible.However, the light emitted from the phosphorescent material is extremely weak compared to the normal light source, so that It is not a good idea to use such a case to obtain sufficient illuminance in an emergency. Therefore, the cover case in this case is transparent. Even if the cover body of the cover case is transparent, a prism-like protrusion is preferably formed on the outer surface of the front plate in order to prevent the internal lamp and circuit components from being seen from the outside. The most effective front plate in the present invention is a light-scattering plate made of a transparent synthetic resin in which triangular pyramidal prisms are evenly arranged on the surface. The above-mentioned light-scattering plate is disclosed in FIG. 1 of JP-B-54-42558, and this light-scattering plate is a point light source as shown in FIG. 5 of JP-B-59-29284. On the other hand, compared with other prism scattering plates of the same kind, it has the property of exhibiting a unique phenomenon. This product utilizes such phenomena and properties in addition to the function of the night light. That is, since the night light is always on only at night, this irradiation light is stored and the light is emitted from the front plate of the lamp cover at the same time as an emergency power failure. The illuminating surface in this proposal is that when it is turned off, it is transparent, but no internal light source is visible, and when the light source is turned on, it is transparent and does not absorb light. When the back surface of the cover case emits light when the light is turned off, if the light source lamp is a transparent lamp, the shadow of the lamp is not created on the illuminated surface, and the entire emitted energy can be externally irradiated light. To do. The phosphorescent material may be a commercially available tape or paint, and it is preferable that a reflective layer is formed on the back surface side of the phosphorescent material. It is also effective to use a phosphorescent material mixed with the back plate material to form a molded product.

【Example】

 In the figure, 1 is a neon bulb or a transparent small lamp, 2 is a rear substrate, and is provided with a simple automatic blinking circuit as shown in FIG. 3 is a photoelectric conversion element such as CdS, and 4 is a plug contact leg to be inserted into an outlet. Reference numeral 5 denotes a lamp cover made of transparent synthetic resin, and a prism uneven portion 6 is provided on the front surface which is an illuminated surface so as not to visually recognize the inside. Reference numeral 8 denotes a band-shaped luminous material, which is attached to the entire side surface or a part of the side surface 7 of the cover. The phosphorescent material may be applied to the surface of the rear substrate 2. When there is a blackout at night, the light emitted from the phosphorescent material passes through the inside of the cover and is diffused from the front prism surface to illuminate the surrounding area. The luminous time of the phosphorescent material depends on the performance of the phosphorescent material, but there is a visible time of 30 minutes or more in the dark, and the surrounding area can be illuminated with sufficient brightness within 5 to 10 minutes. This time is enough for emergency evacuation. FIG. 2 shows a transparent light-scattering plate 10 having a triangular pyramid prism on its surface and a back plate 13 having a phosphorescent material 8 for a lamp cover body 12 having parallel vertical grooves in the thickness direction formed on its side surface 11. The cover case 14 is provided. Reference numeral 15 is a base, and 16 is a lamp socket. It goes without saying that the lamp and the socket may be provided so as to penetrate the back plate. The light emitted from the back plate 13 passes through the transparent lamp 1 and the light scattering plate 10 and illuminates the front surface of the cover as an illumination surface.

【effect】

 As described above, the present invention uses the night-time illumination surface that is always lit at night as the emergency illumination surface, so the location is the same, so there is no risk of confusion and it can be used safely. In addition, the position is usually a position to illuminate the feet in the corridor or the room, and it is fixed to the concentrator, so even if it becomes dark momentarily, the position and direction can be known and evacuation and other necessary actions can be taken. Furthermore, since the emergency illumination is not due to electric energy, it is completely safe without fear of short circuit or ignition even if it is submerged by a sprinkler. Moreover, since it is small and lightweight, it can be installed at a desired location.
