Abstract

PROBLEM TO BE SOLVED: To enhance the visibility of a sight line guiding mark by forming a reflector by use of a translucent synthetic resin containing a fluorescent dye, and emitting the light of a UV lamp to the reflector from the inside or outside of the reflector to excite the emission of the reflector. SOLUTION: A reflector 1 is formed of a translucent synthetic resin containing a fluorescent dye, the reverse side of the reflector 1 is prismatically worked, and it is fitted to the upper part of a frame 2 having strut function. A UV lamp 4 for emitting an ultraviolet ray to the fluorescent dye to promote its excited emission is arranged on the frame 2 located on the reverse side covered with the reflector 1, and a solar battery module 3 as the power source of the UV lamp 4 is fitted to the frame 2 together with the reflector 1. Since an automatic lighting device senses the ambient illuminance in a dim time where the visibility is reduced and lights the UV lamp 4 to excite the fluorescent dye by the ultraviolet ray of the UV lamp for fluorescence, the reflector 1 can be visually confirmed in a wide angle range. The contrast of the self- emitting reflector 1 with the ambient darkness is more increased in the night, and sufficient visibility can be provided.

According to the applicant's invention described in Japanese Patent Application Laid-Open No. H09-217322, a fluorescent dye is added to a light-transmitting synthetic resin of a conventional reflector, so that a fluorescent light is generated by the action of ultraviolet light contained in sunlight. It has been devised that a dye with higher visibility can be provided by exciting the dye and thereby converting part of the invisible ultraviolet region into visible light. That is, in the daytime, a large amount of sunlight is received to increase the brightness of a high fluorescent color, resulting in an excellent visual recognition effect. In addition, the surrounding area is darkened and the visibility is further reduced. Is done. In recent years, particularly in dangerous places, a self-luminous gaze guide that incorporates a light-emitting body such as an LED has been installed in order to more reliably perform gaze guidance at night.

However, even if the daytime visibility is improved, higher visibility is required at twilight and at nighttime when traffic accidents occur frequently, and a reflector that shows gaze guidance is required. Because it can be visually recognized by directly receiving the light of the headlight and retroreflecting it, even if it is a reflector containing a fluorescent dye, it is difficult to see if it is driven without turning on the light at dusk, and it will be a night curve point For example, the retroreflection effect cannot be obtained in a place where headlight is not directly received by the reflector, so that safe driving by gaze guidance is reduced. Particularly in bad weather such as rainy weather, snowfall, or dense fog, extremely careful driving is required, and the role of gaze guidance is strongly required.

In general, self-luminous line-of-sight gaze guides use LEDs or the like. However, these LEDs are expensive in price, so that the amount of installation is small, so that not only the light emitting area is small, but also Since the directionality of the light emitting unit is strong and the viewing angle is narrow, self-emission cannot be recognized only in an extremely limited narrow range.

According to the present invention, as a result of diligent research for achieving the above object, a prism is formed on the back surface, and light incident from the front surface is retroreflected in the direction of the light source by the prism. The reflector is made of a light-transmitting synthetic resin containing a fluorescent dye. On the one hand, a UV lamp is built in on the back surface of the reflector, and on the other hand, the UV lamp is mounted at an aerial position to irradiate the surface of the reflector so that the ultraviolet light of the UV lamp is irradiated on the reflector. The built-in UV lamp has a reflector fitted to the frame, and the UV lamp is disposed on the frame so that the light is emitted toward the back side of the reflector. When a solar cell is taken as a power source, a solar cell unit is mounted on the frame and is electrically connected to a UV lamp. Further, in the form of irradiation from the surface of the reflector, the UV lamp is disposed at an aerial position via the support, and at the same time, a solar cell unit is suitably provided and electrically connected to the UV lamp. In addition, commercial power may be used in consideration of the power consumption of the UV lamp or the supply capacity of the solar cell.
It should be noted that the power supply is provided with an automatic lighting device that blinks upon sensing the illuminance so as to light up at night.

Accordingly, in the daytime, direct or diffuse light of solar ultraviolet light passes through the transparent synthetic resin of the reflector, is refracted and emitted by the prism, and the entire reflector is fluoresced, thereby providing a good visual guide function. At night, the solar cell is used as a power source to irradiate the reflector with a UV lamp, and the ultraviolet dye in the UV lamp excites the fluorescent dye, causing the reflector to emit light in a fluorescent color. Therefore, even when the headlight is not turned on even at twilight, the reflector self-emissions in a fluorescent color by such an action, so that visibility is ensured over a wide area. Further, the reflector is excited by a UV lamp, which is irradiated with a headlight, and emits fluorescent light, becomes retroreflected light refracted by a prism, and is shined and visually recognized. When the reflector is irradiated with the UV lamp regardless of the front and back, the fluorescent dye contained in the transparent synthetic resin forming the reflector is excited to emit fluorescent light, and the light amplified by the refraction diffusion of the prism and It emits strong light.

As the light-transmitting synthetic resin, polymethyl methacryl, methacrylic resin, polycarbonate, polystyrene, acrylic resin and the like are generally used, and as the fluorescent dye, fluorescein, rhodamine, eosin, pyramidine, naphthalimide, Perylene and the like are generally used, but naphthalimide and perylene are preferably used. The reflector is formed in such a state that a translucent synthetic resin mixed with a fluorescent dye as described above is molded by an injection molding machine or the like, and the back surface is subjected to prism processing. The shape of the prism is not particularly limited as long as the light incident on the front surface is retroreflected in the direction of the light source, but in general, the three surfaces are orthogonal to each other in order to widen the reflection angle. The three-sided cut In addition, the front surface does not necessarily have to be a flat surface. For example, if the front surface has a curved surface, the prism processing is performed at an angle that is retroreflected in one direction regardless of the curved surface.

The UV lamp has a wavelength of near-ultraviolet light of 315.
It is sufficient that ultraviolet light of nm to 400 nm can be obtained. For example, a UV fluorescent lamp, a UV cathode tube, a UV light emitting LED or the like is suitably used. The power of the UV lamp may be used by automatically turning on the power stored during the day by the solar cell module at night, or may be used by connecting to a commercial power supply. However, since the power consumption differs depending on the type of the UV lamp, it is selectively used in consideration of the power storage capacity in the location condition of the solar cell.

The UV lamp body 6 only needs to be at a position where the built-in UV lamp irradiates at least the entire surface of the reflector 1 with the UV light from the opening 61. Irradiation may be performed from two or more places depending on the conditions. The crosspiece 62 is supported by the sign plate 5 or the support column 7 to form a hollow, and wiring is inserted so that the solar cell unit 3 and the UV lamp are electrically coupled. The power supply of such a UV lamp uses the power charged during the day by a solar cell at night, and is electrically connected to the UV lamp, and the reflector and the UV lamp are integrated, for example, a support column or the like. A gaze guide mark is provided by internally installing a battery and an accessory member. Further, an automatic blinking device is electrically interposed as a means for turning on and off the power by setting the sunshine time or detecting the illuminance of the surrounding area. It is to be noted that electric power does not always have to be supplied from the solar cell module, and a commercial power supply facility may be provided for a light source having a large amount of electric power or in a situation where sufficient sunlight cannot be obtained.

This is because a so-called fluorescent dye has excellent weather resistance and heat stability, has strong fluorescent power and high chroma, and has excellent miscibility with a light-transmitting synthetic resin. On the other hand, a UV lamp is a lamp that emits near-ultraviolet light having a wavelength of 315 nm to 400 nm.

As described above, since the reflector contains a fluorescent dye and is formed of a prismatic translucent synthetic resin, it is excited by the ultraviolet rays of sunlight during the daytime to convert the ultraviolet rays into visible light. It emits light in a fluorescent color and shines as a gaze guide mark to be visually recognized, thereby enhancing safety. Normally, during dusk hours when visibility is reduced, the fluorescent light emission action is attenuated as the ultraviolet rays of the sun decrease, but the automatic lighting device built in the solar cell unit senses the surrounding illuminance and the UV lamp is activated. When the fluorescent dye is turned on, the fluorescent dye is again excited by the ultraviolet rays of the UV lamp light to emit fluorescent light. Therefore, in the twilight time zone, visual guidance by self light emission is possible over a wide angle.

The self-luminous light allows the driver to fully view and increases the gaze guidance effect. On the other hand, when the light of the car illuminates the reflector, U
Since the retroreflection is performed by the prism with the fluorescent color excited by the V lamp, the fluorescent color is more shining and visible.

According to the present invention, since a fluorescent dye is contained in the transparent synthetic resin forming the reflector, and a UV lamp is radiated from the inner surface or the outer surface of the reflector, the light-transmitting synthetic resin is used. Inside, the fluorescent dye is excited by the ultraviolet rays of the sun and emits a fluorescent color, shines brightly and increases visibility.

At night, the surrounding area is darker, so that the self-luminous function has a sufficient effect. When the light of the car is irradiated on the reflector, the light is retroreflected by the prism with the fluorescent color excited by the UV lamp. It becomes more light and can be visually recognized. Further, unlike the LED light, such retroreflection light can be visually recognized at a wide angle.

Such a reflector, a UV lamp, and a solar cell as a power supply are functionally combined to be compactly formed, and a commercial power supply is not required. It can be installed in a separation zone or the like. Of course, a commercial power supply can be used without using a solar cell. In that case, the solar cell does not have to be incorporated in the self-luminous gaze guide.
