Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-luminous warning indicator lamp using a solar cell.

[0002]

2. Description of the Related Art In particular, self-luminous warning indicator lamps which have a great effect of inducing warning at night are using LED as a light emitting element and a solar battery as a power source in order to simplify installation and save maintenance. . However, due to the power generation performance of a solar cell that is expected to be cloudy and rainy and the performance of a storage battery that requires night-time light emission even when power cannot be generated for a long period of time, there are two types: one with a large solar cell panel and one with a large electricity storage performance. Due to the demand, many of the products are large in size and high in price as a whole, and because it is necessary to install the power generation panel facing the sun, install it while adjusting it to each indicator light, or install a solar panel at the head of the warning indicator light. There were many things that built in and used. However, there were some restrictions that this type of indicator light could not be used, such as the location where the sunlight was not exposed, depending on the road alignment and surrounding conditions.

[0003]

That is, according to the present invention, the light emitting unit is made relatively small as much as possible, and it is not necessary to adjust each solar cell panel toward the sun, and maintenance is not required. Rainy weather, where the light doesn't shine,
It is intended to provide a warning indicator light that does not limit the installation location of the power generation panel by generating power, charging and emitting light even in cloudy weather in regions where there is little sunshine in winter and in cold regions where temperatures can even reach -40 ° C. Is.

[0004]

A secondary battery conventionally used in a solar power generation unit has a charge / discharge cycle of 200 to 50.
Lead-acid batteries and nickel-cadmium batteries, which have a life of 0 times, are mainly used. This is large in volume and usually requires simultaneous replacement within 2 to 4 years. Further, since this storage battery contains heavy metals, it needs to be recovered when it is discarded. This kind of maintenance is not a minor issue, in comparison to price.

In view of this, the present invention calculates the amount of light emission power that can secure the time required for the illuminance around the blinking light emission by the LED and the brightness required for the warning effect, and determines the capacity of the solar cell capable of generating the amount of light emission. To do. The capacity of the electric double layer capacitor capable of charging the generated electric power corresponding to 1.5 days worth is determined by actually taking allowance.

Thus, if there is a certain brightness even in rainy weather,
In many cases, the LED is ready to secure electric power capable of flashing and emitting from early in the evening to late in the morning. Here, the amount of power generated by the solar cell is provided with an overvoltage protection circuit that shuts off the current from the solar cell when the electric double layer capacitor is fully charged.

[0007]

Since the electric capacity is determined as described above, the solar cell constantly sends the electric power for 1 to 1.5 days of the discharge of the LED blinking light emission to the electric double layer capacitor, and the solar cell is also in the power decay due to the light emission. If the situation where the power is generated is aligned, it is possible to constantly replenish the power generation → charging. The electric double layer capacitor has a significantly larger number of charge / discharge cycles than a general secondary battery and has a life of 10 years or more. Therefore, the labor of battery replacement is reduced, and no pollution problem occurs when it is discarded. Since the charging capacity for the power consumption for one day is sufficient, the volume of the electric double layer capacitor is relatively small and lightweight. Therefore, it is possible to reduce the weight of the power-generating light emitting portion of the self-luminous warning indicator light.

Further, in order to reduce the power consumption for light emission by the LED and to increase the warning effect, blinking light is usually used, but it is usually installed at a pitch of 5 to 40 meters on the roadside because of its role as a warning indicator light. However, it is difficult for the solar cell type self-luminous warning indicator lamp to synchronize the blinking at this time unless it is wirelessly controlled. It is possible to solve the problem of synchronization / non-synchronization of blinks by making the number of blinks faster and making them appear to be nearly continuous lighting while maintaining the warning effect by making them appear to blink.
To produce this effect, the number of blinks is 200-400.
It is good to set it to once / minute.

In this self-luminous warning indicator lamp, a solar battery power generation panel that generates power to cover the daily amount of the light emitting portion even in rainy weather is a normal warning indicator lamp with a thickness of 76.3Φ or more. When it becomes too big to fit in the head, it can be installed on the side of the pillar. That is, this is one of the advantages that it can be charged even in rainy weather.
When the light emitting part is directly faced to the vehicle, the solar cell panel can be made to have a unified specification behind the light emitting part. This reduces the chance that the light emitting section and the power generation panel section will be damaged at the same time.

Further, by utilizing the characteristics of the electric double layer capacitor having a wide operating temperature range of -40 ° C. to 70 ° C., which is low temperature that cannot be used in ordinary storage batteries, a warning display including an all-weather self-luminous gaze target The light is completed.

[0011]

Embodiment 1 A solar cell type warning indicator light according to the present invention will be described with reference to the drawings as a gaze guide. A solar cell type unit of another block diagram is placed in the guided sample head 1 or the support column 3, the power generation panel 2 is installed on the support column 3, a plurality of light emitting LEDs 4 are provided on the head 1, and a light emitting device by electric power is used. If there is a problem with the, provide a reflector 5 to complement it.
Thus, the solar cell unit according to the present invention serves as a self-luminous visual guide marker by performing power generation and charging even in rainy weather in northern countries where there is little sunlight, and light emission and discharge at night.

[0012]

[Embodiment 2] An embodiment in the case of being applied to a small road stud for the same purpose will be described with reference to the drawings. It is a solar cell type self-luminous road tack that is usually attached and installed on the roadside side stones, but the solar cell power generation panel 7 is placed in the center of the tack body 6.
, And the power generation / emission control unit 8 underneath. The electric double layer capacitor 9 is placed in the gap at that time. Then, the light emitting section LED 10 is put in a place corresponding to the front surface, and a warning light is emitted from the whole surface light emitting window. In this embodiment, it is sufficient to have an electric capacity for emitting two large-sized LEDs. Therefore, 15 cm × 12.
The solar cell power generation and charging / discharging unit can be housed in a tack having a size of cm or less.

[0013]

Since the present invention is configured as described above, it has the following effects.

Power generation and charging can be performed even on a day when sunlight is not shining, such as in the case of rain or snow, and it is possible to cope with light emission and blink discharge at night, so that it does not emit light depending on weather conditions, In addition, the power generation panel may be installed in any position, and there is an advantage that the position of the panel need not be adjusted.
