Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a flashlight used indoors and outdoors at night, a headlight of a bicycle, a car, a helmet, etc., and a lighting fixture such as an interior light.

[0002]

[Prior art]

 Conventionally, problems with lighting fixtures used outdoors at night include the need to turn off the lights occasionally due to the battery life being reduced by the continuous lighting of flashlights, and the low illuminance of the headlights when the bicycle is traveling at low speeds. Etc. have been pointed out. As a solution to these problems, a method of attaching the phosphorescent material to a part of the reflector of the lamp is practically used as a method of releasing the illumination energy accumulated during lighting to provide the illuminance required for several minutes to several hours. It is disclosed in Japanese Patent Registration No. 30197 68. However, in this method, the luminous body is attached to the reflector so that the illuminance when the lamp is lit is considerably reduced, and the luminous body is opaque, making it difficult to mark various symbols, characters, patterns, etc. is there.

Also, indoors, a phosphorescent body is used as a guide for power outages in the event of a disaster such as an earthquake. However, since the phosphorescent body is opaque, it should be installed near a lighting lamp. Limited applications.

[0004]

[Problems to be solved by the device]

 The present invention utilizes the illumination energy of a lighting lamp to release the stored energy when the lamp is turned off or when it is in a low illuminance state to obtain the illuminance required for several minutes to several hours, and various symbols, The purpose is to provide a lighting fixture that can display letters and patterns.

[0005]

[Means for Solving the Problems]

 As a result of earnest research in view of the above, the present invention has been achieved by coating the whole or a part of the inner surface or the outer surface of a lens or a cover of a lighting fixture with a translucent phosphorescent material. The coating method is as follows: Cut out and attach a translucent phosphorescent light transfer seal or sheet to the lens or cover of the lighting equipment, apply a phosphorescent substance-containing paint in a translucent manner, and transmit the phosphorescent substance-containing ink with a silk screen. It is carried out by various methods such as direct printing on the light property or coating the phosphor by light-transmitting property.

The invention of claim 2 is a flashlight in which a lens or a transparent cover on the front surface of a light bulb is coated with a light-transmissive luminous body on the inner or outer surface thereof.

A third aspect of the present invention is a headlight for an automobile, a bicycle, or a helmet, in which a light transmissive phosphorescent material is coated on the inner surface or the outer surface of a lens or a transparent cover on the front surface of a light bulb.

Further, the invention of claim 4 is a luminaire in which an inner surface or an outer surface of an opaque cover is coated with a light-transmissive luminous body, and the opaque cover is made of a material such as Japanese paper, glass, or plastic. The light bulb here may be another light emitting body such as a fluorescent lamp.

As the phosphorescent material, a sulfide-based phosphorescent material that has been conventionally used is also used, but an aluminate-based phosphorescent material is preferable, and an aluminate-based phosphorescent material is particularly preferable in order to further improve emission brightness and afterglow characteristics. It is preferable to use strontium or calcium aluminate as a base crystal, to which europium is used as an activator, and decyprosium or neodymium as an activator.

[Embodiment of the invention]

 Embodiments of the invention will be described based on examples with reference to the drawings. Fig. 1 is a cross-sectional view of a flashlight in which a transparent light-emitting material is dispersed in transparent ink is printed directly on a transparent cover glass of the flashlight by a silk screen in a light-transmitting manner. It is a front view.

FIG. 3 is a cross-sectional view in which a translucent luminous emission transfer seal is attached to the inner surface of a transparent cover of a vehicle headlight, and FIG. 4 is a front view thereof.

FIG. 5 is a cross-sectional view showing a state in which the inner surface of the transparent cover of the helmet headlight is coated with a phosphor by a sputtering method.

FIG. 6 is a perspective view showing a state in which a translucent light-emitting emission transfer seal is attached to the outer surface of the cover of the Washi paper cover interior lamp.

[0014]

[Effect of the invention]

 The present invention is configured as described above, and has the following effects.

By coating the lens or cover on the front surface of the light bulb with a light-transmissive light-emitting luminescent material, the illumination energy of the lighting lamp is used to store light, and the stored energy is emitted when the lamp is turned off for a long time. It is effective for confirming the owner and various advertisements because the place where it exists can be visually confirmed and symbols, characters, patterns, etc. can be displayed.

The effect of the flashlight of the present invention is that the luminous phosphor is translucent, so that the lens or transparent cover on the front of the light bulb can be easily coated in various shapes, and when the battery is dead, the battery To prolong the life of the product, it is effective for visual confirmation when using it with the light off sometimes.

The effect of the headlight of the present invention is the same as that of the flashlight described above for the helmet headlight, and the effect of the headlight of the bicycle is temporarily stopped or at a low speed at an intersection with few streetlights. It is effective for visual confirmation when driving, and for automobile headlights, in addition to visual confirmation at intersections, the headlight area is large, so it is possible to coat the luminous phosphor in various shapes, making it possible to store in dark places. It is also effective for checking your own car at the parking lot and various advertisements.

As for the effect of the luminaire in which the opaque cover of the present invention is coated with the translucent luminous phosphor, the effect as an auxiliary light for emergency evacuation in the event of a natural disaster is obvious. A variety of shapes can be coated directly on an opaque cover made of resin or resin, and a transparent color coat can be applied on the translucent phosphorescent material. Various patterns can be displayed on the lighting fixtures, and various tastes can be enjoyed.
