FIG. 3 is a half sectional view of a color cone illumination system using a color cone illumination rubber base according to an embodiment of the present invention, and FIG. 4 is an external view showing an LED arrangement as viewed from an arrow A according to the embodiment of the present invention. FIG.
1-4, 100 is a color cone blow-molded with, for example, plastic, 101 is a recess provided to improve the reflection efficiency, 102 is a reflective material provided on the surface of the color cone 100, and 103 is a color cone 100. Light retroreflective materials 170 and 270 provided on a part of the surface are holes for fixing to the ground with a pile or the like through holes provided in the color cone 100 and the rubber base 200 to prevent theft. A light emitting diode (hereinafter referred to as LED) 210 emits red illumination light 211 that illuminates the color cone 100. 220 is a solar cell, 230 is a secondary battery, and 240 is a circuit such as a light emission control circuit. Reference numeral 250 denotes a waterproof case for housing 240 such as a light emission control circuit other than the LED 210 and the solar battery 220.
By installing a solar system consisting of LEDs 210, solar cells 220, etc. in the structure of the rubber base 200, attaching a light emission control circuit 240 to charge and store electricity in the daytime, and to have a structure that turns on and blinks LED lighting at night A structure that performs upright illumination from the bottom of the color cone can be made.
When the plastic resin molded product is separated from the heavy rubber base 200 so as to cover the upper part of the rubber base 200, there is an advantage that the installation and movement at the site can be easily performed.

The number of LEDs 210 used is 8 in the case of 4 corners and 2 stations, and 12 in the case of 3 stations, but the power consumption of each red LED is 0.02 to 0.05 W / h. If the capacity of the battery is 2.5 VA, considering that the day when it is not sunny with a duty ratio of 20% lasts for a maximum of 3 days, it is possible to flash on and off at night 12 hours × 3 days. When the total sunlight area is 200 cm ² , the total amount of solar radiation in the daytime is 4 hours, the annual solar radiation is 1 kW / m ² , the incident angle plane is sin30 ° = 0.5, and the power generation efficiency is 10% with amorphous silicon solar cells. When the average value is converted into generated power, 4 Wh is generated. By boosting this generated power with a converter and storing it in a secondary battery, the nightly usage time is surely supplemented, but it is necessary to provide a separate daily charging system in case of deterioration or emergency use. is there. The number of LEDs 210 used is not limited to the above example, and the required illumination intensity can be obtained by the light distribution curve of the LEDs 210 and the reflection characteristics of the color cone 100.

The visibility of the color cone 100 is ensured by the blinking illumination of the LED 210, and when a high-intensity reflective sheet is pasted as the reflective material 102, the color cone 100 itself becomes reflected illumination, and a safe viewing distance of 150 m or more can be secured.
The strobe light of about 0.01 to 1 ms uses the afterimage phenomenon that remains as good as the continuous lighting of the human eye, and the blinking method uses a blocking transmission (relaxation transmitter) by a multivibrator to greatly reduce the duty ratio. Flashing is performed once every 0.5 to 2 seconds by the flash method for about 0.01 to 1 ms. Power consumption can be reduced to 1/500 to 1/200000 of continuous lighting by a multivibrator circuit that stably oscillates even when the duty ratio is greatly reduced. By doing so, a practical night lighting time can be obtained with an area of 100 cm ² of the solar cell 220 that can be installed horizontally on the base of the color cone 100. Furthermore, if it is set to 45 ° -60 ° southward at the time of installation rather than horizontally, it is easy for rain to flow, so that it is difficult for dust to flow and accumulate, and at the same time it can shine light vertically on the weak light of winter, so maximum power generation It is possible to average power generation throughout the year. Furthermore, a 0.2 to 1 μm film is formed by applying an aqueous inorganic silica agent (trademark of NTRC Co., Ltd.) on the glass surface 221 that is the sunlight incident surface of the solar cell 220 and condensing a hydrophilic film. Let The water-based inorganic silica agent is nano-scale fine silica, and the film-forming surface retains hydrophilicity, and the contact angle is about 10 degrees. Can float from. The water may be rain or splashing water from vehicles, and can provide self-cleaning that naturally removes dirt and oil stains and prevents power generation efficiency from being reduced due to dust and dirt. . The inorganic silica agent applied to this device possesses the maximum antifouling property at a wavelength centered on the ultraviolet wavelength of 300 nm, which is abundant in sunlight. . The protective film-forming paint used may be either a water-based inorganic silica agent (manufactured by NTRC Co., Ltd.) or a hydrophilic group paint containing hydrophilic group silicon or titanium oxide as long as the same performance is ensured.

FIG. 5 is a color cone illumination rubber base block diagram according to the embodiment of the present invention, and FIG. 6 is a color cone illumination rubber base circuit diagram according to the embodiment of the present invention. The backflow prevention circuit 260 uses a diode to prevent backflow when the solar cell 220 is not generating power.
By using the general multivibrator circuit 251 shown in FIG. 6 in the light emission control circuit of FIG. 5, the duty ratio is greatly lowered and flashing is performed once in about 0.5 to 2 seconds by the flash method for about 0.01 to 1 ms. Even in the light emitting diode 210 that can pass only a small current, the average current can be made very small, and a clear current distance can be further extended by a large pulse current. Since the multivibrator circuit is a basic circuit described in textbooks, its explanation is omitted. Further, the light emission control circuit uses CDS or the like to detect the brightness of the installation location, and saves power by operating only at night. As a power source, a low-power solar system or a dry battery that wants to reduce the number of replacements as little as possible. A small rechargeable battery can be used effectively to reduce costs. The LED 210 is a 1.5V dry battery, a nickel cadmium storage battery 1.2V, and a nickel hydride storage battery 1.2V. For example, when there is no nickel hydride storage battery 1.2V, an alkaline dry battery of the same size is used temporarily. If the power supply voltage of the lighting circuit is designed to be 1.2 V × n (the number of batteries), both can be replaced. The weight of these batteries has the same effect as the current weight made of rubber rubber, and also prevents the lightweight color cone from falling or dissipating. Boosting may be performed simultaneously with a relaxation oscillation circuit using a transformer instead of the multivibrator circuit. In this case, the voltage of the entire circuit can be lowered, which is convenient.

  In addition, by using Sanyo Electric's ENELOOP (registered trademark), which is a nickel metal hydride battery, as the secondary battery 230, the number of times of charge / discharge can be increased compared to a normal nickel metal hydride battery, and the self-discharge is particularly small. The base or eneloop can be stored and installed on site as needed. In this way, the storage volume can be greatly reduced compared to storing the entire color cone. In addition, eneloop has a low memory effect and can be charged repeatedly before it is completely discharged. From environmental issues, it is possible to provide ecologically-friendly products that can handle waste disposal problems and effectively use energy resources. It is. Furthermore, secondary batteries with a memory effect require a complicated refresh operation in order to restore the charge capacity when new, but an eneloop with less memory effect that is not required for a complex refresh operation for use in the field is optimal. . In order to use a secondary battery with a memory effect without complicated refresh operations, it is necessary to use a large-capacity secondary battery in anticipation of a decrease in charge capacity from the beginning. And self-discharge increases, but this can be prevented.

FIG. 7 is a block diagram of a color cone illumination rubber base according to an embodiment of the present invention.
Since one of the solar cells 220 has only 0.5V, the booster circuit is used to boost the voltage to the optimum voltage for charging the secondary battery 230, thereby reducing the number of necessary solar cells 220 in series and using the charge control circuit. Thus, it is possible to charge efficiently and in a short time while preventing overcharge. If one of the solar cells 220 in series is contaminated with, for example, fallen leaves or mud, the internal resistance becomes high and the generated power is greatly impaired. Even when the same generated power is obtained by using the boost converter circuit, the number of series is reduced, and the large-area solar cells 220 are connected in series with a small number. By doing so, it is possible to reliably generate power by reducing the possibility that the solar cell surface is covered with fallen leaves and mud, resulting in high internal resistance. The secondary battery 230 used in this system is a lead storage battery, nickel cadmium storage battery, nickel metal hydride storage battery, lithium ion storage battery, each of which is pre-charged and replaced, or using a solar battery rechargeable at the site of use. Is also possible. In addition, a large solar panel is installed separately, and the power is drawn to the rubber-based structure to charge the storage battery to the optimum voltage for charging by the booster (converter) circuit, thereby ensuring long-term use for power storage. .

  The visibility of the color cone is ensured by flashing illumination, and when a retroreflective high-reflective reflective sheet with a red filter is applied, the color cone itself becomes a red reflector, and light is emitted from the headlights of automobiles, motorcycles, and bicycles. Since the light is concentrated as it is as reflected light and reflects the red light in the direction of the incident light, a visible distance of 150 m or more can be secured at night.

In the case of paper, it can be made cheaper by waterproofing, and the storage space can be saved more.
