A base material for the cover is formed of a mixture material of a transparent and colorless synthetic resin and the light storage agent, and a surface of the base material is coated with a titanium oxide solution. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention is a cover that is disposed around a lighting fixture, and in particular, lighting that exhibits excellent effects when power is reduced and disasters occur by emitting light with high brightness for a long time even in the dark after being turned off. It relates to an instrument phosphorescent cover.

2. Description of the Related Art Conventionally, there are shades that have a light decoration hardening, with patterns and designs changing between daytime and nighttime. (For example, refer to Patent Document 1).
JP-A-11-167807

  However, the shade of the above-mentioned Patent Document 1 includes a paint containing an ultraviolet light-emitting substance that emits light by irradiating ultraviolet light onto a translucent base material, and a paint containing a phosphorescent substance capable of emitting light for a long time. A pattern is formed with a paint made of pigment or the like. As a result, the manufacturing process becomes complicated, and the problem is that the cost is increased.

  Therefore, the present invention provides a luminaire phosphorescent cover that can exhibit excellent energy saving and disaster countermeasure effects due to the luminous characteristics of the phosphorescent agent, even after the light is turned off or during a power failure, the entire cover emits light with high brightness for a long time in the dark. It is to provide.

  In order to solve the above-mentioned problem, the lighting fixture phosphorescent cover of the present invention is a cover disposed around the lighting fixture, and the base material of the cover is a mixture of a colorless and transparent synthetic resin liquid and a phosphorescent agent. It is formed of a material. Further, a titanium oxide solution was applied to the surface of the substrate.

  The cover base of the luminaire is made of a mixture of a colorless and transparent synthetic resin liquid and a phosphorescent agent, so that the phosphorescent agent accumulates the light emitted from the luminaire and the entire cover is dark even when it is turned off. It can continue to emit light with high brightness for a long time. As a result, power consumption can be significantly reduced, and even when a disaster such as a fire or earthquake occurs, the surroundings of the lighting fixtures are illuminated brightly even if a power outage occurs, which can also demonstrate excellent effects in disaster countermeasures. .

  Further, by applying the titanium oxide solution to the surface of the base material, it is possible to realize air purification and reduction of dirt adhesion by photocatalytic action.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of a lighting fixture phosphorescent cover according to the present invention will be described below with reference to the drawings.
The lighting fixture phosphorescent cover 1 of the present invention shown in FIG. 1 is disposed around an existing lighting fixture a, and has a function of protecting the lighting fixture a and softening light emitted from the lighting fixture a. The lighting fixture phosphorescent cover 1 is widely mounted on the ceiling of a building, a store, or the like from the ceiling of the train, the subway, and the Shinkansen shown in FIG. Moreover, in the lighting fixture a accommodated in the lighting fixture phosphorescent cover 1, the incandescent lamp shown in FIG. 4 may be used in addition to the fluorescent lamp as shown in FIG.

  Moreover, the lighting fixture phosphorescent cover 1 is not limited to a type that fits in a ceiling in a room or a train, but may be a hanging type as shown in FIG. Furthermore, the lighting fixture phosphorescent cover 1 may be formed in a square shape, a cylindrical shape, an elliptical shape, or the like.

  In particular, the base material 2 of the lighting fixture phosphorescent cover 1 is formed of a mixture of a colorless and transparent synthetic resin liquid and a phosphorescent agent. As the synthetic resin, a thermoplastic resin liquid is particularly preferable, and examples thereof include materials such as transparent acrylic, polyethylene, and polypropylene that soften into a liquid state when heated and show plasticity and solidify when cooled.

  The phosphorescent agent stores ambient light and enables spontaneous light emission, and is formed by mixing a plurality of known metal compounds and rare earths and mixing a general-purpose color developing agent. This luminous agent can emit enough light power to confirm the surrounding situation even if the surroundings become dark after extinction.

  The mixed material is formed by mixing a transparent synthetic resin liquid and a phosphorescent agent at an appropriate ratio, for example, 50:50. And after shape | molding this mixed material in a desired shape according to a type | mold, the lighting fixture luminous storage cover 1 is formed by making it harden | cure or cool and solidify. By arranging the lighting fixture phosphorescent cover 1 around the lighting fixture a, the light accumulated in the phosphorescent agent is emitted after the light is turned off, and the entire cover is illuminated with high brightness in the dark. Therefore, in addition to reducing power consumption, even if a power outage occurs in the event of a disaster, the surroundings of the lighting fixture can be illuminated brightly, and an excellent disaster countermeasure effect is exhibited. The ratio between the synthetic resin liquid and the phosphorescent agent is not particularly limited, and for example, by adjusting the ratio of the phosphorescent agent compared to the synthetic resin liquid, the emission luminance can be arbitrarily changed. Become.

  As another preferred example, as shown in FIG. 3, it is preferable to apply a titanium oxide solution 3 to the surface of the substrate 2. The titanium oxide liquid 3 is composed of an amorphous titanic acid solution (PTA sol) and a peroxo modified anatase (PA sol). Due to the photocatalytic function of the titanium oxide liquid 3, dirt such as dust or dirt is deposited on the surface of the lighting fixture phosphorescent cover 1. Can be reduced. It is also possible to purify the air around the lighting fixture.

It is sectional drawing of the lighting fixture luminous storage cover of this invention. It is an expanded sectional view of the said lighting fixture phosphorescent cover. It is an expanded sectional view of the lighting fixture phosphorescent cover which shows another suitable example. It is sectional drawing of the lighting fixture luminous storage cover which accommodated the incandescent lamp. Represents a hanging luminaire phosphorescent cover. The lighting fixture phosphorescent cover of the present invention represents a state where light is emitted in the dark. The use condition of the lighting fixture phosphorescent cover of this invention is shown.
