Description

Guiding light on the road using the power of wind and solar heat}

The present invention relates to a road light, and more particularly, by installing windmills and solar cells on a road, wind and solar energy for lighting the light using wind energy obtained by windmills and electrical energy generated by solar cells. It is about road marking used.

For safety at night, central dividers and lanes on roads have been used to reflect reflecting headlights of vehicles, or fluorescent plates coated with paint containing fluorescent materials. In addition, a reflection plate or a fluorescent plate has been used for warning directions on national roads and warning lights for construction sites. In special situations such as road construction, special attention from the driver was required, and a flashing light using a general current was used to more clearly indicate the road condition.

The road display device using the above-mentioned fluorescent material is inferior in visibility over time after installation due to the nature of the fluorescent material, and the reflecting plate reflecting the vehicle headlights is also affected by the adhesion of many foreign matters on the road such as dust to the surface of the reflecting plate. The display function is degraded. Also, in bad weather conditions, such road marking apparatuses are markedly degraded to increase the risk of an accident.

On the other hand, road indicators that are flashing using normal current are not easy to install, and there is a problem that the current consumption is considerable. have.

Although road signs using solar cells have been developed for such a problem, power generation mechanisms using solar cells only have low power generation capability when foreign matter adheres to the surface of solar panels due to bad weather or long-term use. The reliability was low.

Therefore, the object of the present invention,

It can keep the display function stable even in bad weather.

Despite the adhesion of various foreign matters on the road such as dust, the display function can be maintained for a longer time.

To provide a road light that is easy to install and consumes no power.

The object of the present invention as described above,

Wind-powered wind turbines, wind power generation units that generate electrical energy using the rotational force of windmills, solar power generation units that generate electrical energy using solar heat, and electrical energy generated by wind power generation units and solar power generation units. The charging unit for charging the light, the lighting unit is turned on by the power charged in the charging unit, and the electric energy generated to control to maintain an optimal state of charge and to control the lighting or turning off the lighting unit according to the bright and dark state on the road It can be achieved by a road indicator using wind and solar energy including a control unit.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a road indicator using wind and solar energy according to the present invention.

The windmill 1 is rotated by the wind generated by the natural wind or the driving of the car. In order to increase the rotational speed of the windmill can be equipped with a rotational transmission portion 10 consisting of several gear trains, thereby generating more electrical energy can be expected. The rotational energy of the windmill 1 is converted into electrical energy by the power generation unit 20.

The solar cell 2 generates electric energy during a clear day and is charged.

Electrical energy generated from the windmill 1 and the solar cell 2, respectively, is input to the power conversion and charging unit 30 and 50 through a backflow prevention device, and the power conversion and charging unit 30 and 50 is connected to the storage battery 60. Charge under controlled voltage and current to charge the maximum current according to the capacitance. Here, the charging method is based on the power conversion and charging unit (30, 50) provided independently from each of the wind power generation unit and the solar power generation unit. The controller 70 performs a maximum power point tracking method in order to maximize the energy generated by the windmill and the solar heat. In addition, the control unit 70 includes an optical sensor to detect a bright and dark state around the road, thereby allowing the indicator of the lighting unit 40 to turn on, off or flash.

Another embodiment of the present invention is as follows.

If the road is not suitable to use solar heat, or the situation does not require a lot of current, it can be used for road markings with a wind power generator.

In the illustrated embodiment, the size and shape of the windmill for wind power generation can be made to suit the characteristics of the installation site.

Since the road indicator using wind and solar heat according to an embodiment of the present invention is turned on by sufficient power, the driver can clearly determine the road situation even in bad weather conditions, thereby enabling safe driving at night. In addition, despite the adhesion of various foreign matters on the road such as dust, the display function is maintained for a long time, thereby reducing the cost and labor required for maintenance. In addition, since there is no power consumption, costs other than installation costs are reduced. As in another embodiment of the present invention, the road sign that is generated using only wind power, the manufacturing cost is further reduced.
