Description

Solar And Wind Delineator

The present invention relates to road and traffic safety facilities, and to an LED delineator that uses solar and wind power at the same time. The LED delineator is used to guide the driver's gaze on the road by emitting LEDs with electric energy. As a method of supplying electricity to the LED, a method of using an externally supplied power source or a method of supplying electricity through self-generation using an electric device composed of its own power generation and storage device is utilized.

Self-powered LED delineators with their own electric devices include solar delineators that use solar energy and wind delineators that use wind power, which are provided by utilizing natural power. Delineators are installed to help drivers accurately recognize the location of their lanes when driving at night and to guide vehicles not to invade their lanes, thereby establishing traffic order and promoting safe driving. In other words, they are installed on roads and used for lane guidance and regulation, sidewalk and lane separation marking, safety zone marking, crosswalk marking, and preventing collisions with dividers. In addition, delineators are installed to block illegal U-turns in areas where there is frequent movement to intersection waiting lanes and lanes without signals, and to regulate entry into other lanes in areas with large turning radiuses or high risk of accidents.

The solar LED delineator can detect day and night through a photo sensor, and accordingly, electric energy is stored in the battery only during the day, and at night, the electric energy stored in the battery is supplied to the LED, so that light is emitted from the LED. The solar LED delineator supplies electric energy to the LED, so that light is emitted from the LED, not only at night, but also when fog occurs due to a change in the weather, the weather suddenly gets dark, or in bad weather.

In this way, the solar LED delineator operates only with sunlight and is semi-permanent, requiring no separate power supply. It can fully function as a delineator if properly maintained after a single installation. In addition, the solar LED delineator can be charged with its daily power consumption with a single battery charge, and can continuously emit LED light for, for example, 5 to 7 days using electricity from the battery even on long, cloudy days. The related solar LED delineator is disclosed in Korean Patent No. 992851 (2010.11.02), and reference is made to FIG. 1 and FIG. 2.

A delineator equipped with a wind turbine obtains alternating current from a wind turbine that generates electricity by rotating horizontal and vertical blades due to natural wind or wind generated when a vehicle is running, converts this alternating current into direct current, and lights up a light emitting diode (LED) to indicate a road boundary. Patent No. 1145765 (May 7, 2012) regarding a delineator equipped with a wind turbine is disclosed, and FIG. 4 is referenced herein for citation.

The LED part (10) includes a fixed band (180), and the fixed band (180) is formed on the bottom surface of the main body (130) of the LED part (10) with a fixed band (180) that takes a ring shape corresponding to the band fixing groove (383), and the fixed band (180) is formed by having a plurality of LED side bolt holes (188) drilled at equal intervals corresponding to the wind power generation side bolt holes (388).

The supply of electric energy from the wind power generation unit (30) to the LED unit (10) is achieved by providing a conductive member (a11)(a12) on the inner surface of the first guardrail (381) and the inner surface of the second guardrail (382), respectively, and correspondingly providing a conductive member (a21)(a22) on one side and the other side of the fixed band (180), so that when the fixed band (180) is interposed in the band fixing groove (383), the opposing conductive members (a11:a21)(a21:a22) come into contact so that the two poles (+,-) of the electric energy are respectively conducted.

Depending on the road environment, in each case of installation on a flat surface, side surface, or slope, a fixed band (180) is inserted into a band fixing member (380), then rotated (r1) at a required angle, and then the bolt hole (388) on the wind power generation side and the bolt hole (188) on the LED side are aligned, and then tightened with a fixing element (b1) to secure.

Solar and wind power delineators are a way to achieve green growth by using solar energy, an infinite natural energy source, to store electrical energy during the day and to emit LEDs at night. In addition, even when there is insufficient sunlight or the environment is at night, they can continuously generate power using wind power to supply power to the LEDs without an external power supply. In particular, they are easy to install on roads and offer a durable configuration.

The present invention relates to a self-powered solar energy and wind energy LED delineator including a solar power generator that generates electric energy using solar energy and a wind power generator that generates electric energy using wind energy. First, general information regarding an LED delineator that supplies electric power by self-power generation will be examined with examples of FIGS. 1 to 3.

The solar LED delineator (100) according to FIGS. 1 and 2 includes an LED (110), a reflector (120), a body (130), a cover, a fixed shaft (150), a solar panel (160), a battery (170), a circuit board (180), and a fixed support (190).

The LED (110) above is a semiconductor element that converts electric energy into light energy and emits light, and creates injected minority carriers (electrons or holes) by utilizing the p-n junction structure of the semiconductor, and emits light by their recombination. The LED (110) is inserted and fixed into an LED insertion groove (122) formed on the inner surface of the reflector (120). The reflector (120) reflects the light emitted from the LED (110) and emits it more brightly to the outside. To this end, the reflector (120) may be formed of a material suitable for reflecting light, such as acrylic or polycarbonate (PC). The reflector (120) has an LED insertion groove (122) on its inner surface and a reflective protrusion (124) on its outer surface.

The case (132) may be formed with a structure in which both sides are open or only one side is open so that the reflector (120) can be placed on both sides. In other words, the case (132) may be formed with a structure in which one side is open so that the reflector (120) can be placed on only one side of the two sides. The connecting portion (310) is formed to extend from the case (132), and the extended end is connected to the fixed support (190).

The photo sensor detects the illuminance of the solar light and outputs a voltage corresponding to the detected illuminance. When the detected illuminance is below a certain illuminance, the switch operates in a night mode to supply electric energy stored in the battery to the LED. When the output voltage of the photo sensor (730) is below a reference voltage, the switch may operate in the night mode, and when the output voltage of the photo sensor (730) exceeds the reference voltage, the switch may operate in the day mode. The control unit (750) may control the overall operation of the solar panel (710), the battery (720), the photo sensor (730), the switch (740), etc. of the driving device (700) of the solar LED delineator.

A delineator equipped with a wind power generator according to an example of FIG. 3 obtains alternating current from a wind power generator that generates power by rotating horizontal and vertical blades due to the wind generated when a vehicle is running, converts the alternating current into direct current, and lights up a light-emitting diode to indicate a road boundary. A cylindrical body (320) having a wind inlet (321) formed through the center to be installed so as to face a vehicle running on the road boundary and to indicate the road boundary is formed with a connecting portion (310) on the lower side, and a wind power generator (360) and a plurality of light-emitting diodes (400) are installed inside the body (320) so as to face forward. Fixed ribs (322) are formed on the upper and lower parts of the body (320) of the delineator (300), and a wind power generator (360) is installed between the fixed ribs (322) and generates power by the wind generated when a vehicle is running.

The delineator (300) includes an AC/DC converter (370) that converts AC provided from the wind power generator (360) into DC, and a storage unit (380) that charges and discharges the DC provided from the AC/DC converter (370) to light up the plurality of light-emitting diodes (400) to indicate a road boundary. The wind power generator (360) is installed between fixed ribs (322) formed at the upper and lower parts of the body (320), and a connecting line is connected to the AC/DC converter (370), and a rotary blade (363) that is mounted on a power generation shaft (362) of the wind power generator (360) and rotates by the wind.

Hereinafter, with reference to examples of FIGS. 4 to 7, an LED delineator that simultaneously utilizes solar energy as well as wind energy generated by natural wind and vehicle traffic will be specifically described. The solar and wind power delineator of the present invention includes a solar power generation unit (20) that generates electric energy with a solar panel (160) using solar energy; a wind power generation unit (30) that generates electric energy with a wind power generator (360) using wind energy; and an LED unit (10) that includes a main body (130) equipped with an LED that receives, controls, and utilizes the generated electric energy to emit light. The individual and specific configurations, operations, etc. of the solar power generation unit (20) and the wind power generation unit (30) will be cited from prior art. The present invention provides a wind power generation unit (30) in which an LED unit (10) and a solar power generation unit (20) can rotate to adjust the rotation angle. To this end, a fixed band (180) is provided that can slip and rotate around a band fixing unit (380) of the wind power generation unit (30) as a rotation axis, and the fixed band (180) is provided as a body that is firmly fixed to the LED unit (10) so that they do not move with each other.

The wind power generation unit (30) includes a band fixing unit (380). The band fixing unit (380) includes a first guardrail (381), a second guardrail (382), a band fixing groove (383), and a wind power generation-side bolt hole (388). The first guardrail (381) and the second guardrail (382) are provided in a plurality of two pairs, each of which has a ring shape and a pair of protrusions that protrude further outward from the outer periphery of the body (320) of the wind power generation unit (30). The first guardrail (381) and the second guardrail (382) are spaced apart from each other in a regular manner, and a band fixing groove (383) that is sunken in a concave valley shape is formed between them. And, in the band fixing home (383), at least one or more wind power generation side bolt holes (388) are formed at equal intervals along the outer periphery of the body (320) of the wind power generation unit (30).

The LED part (10) has an '8' shape including a fixing band (180) at its bottom. The fixing band (180) is formed in a ring or band shape corresponding to fit into the band fixing groove (383), and its upper part is attached to the bottom surface of the main body (130) of the LED part (10) or is provided to extend from the bottom surface. A plurality of LED-side bolt holes (188) are drilled into the fixing band (180), and are arranged at equal intervals corresponding to the wind power generation part-side bolt holes (388).

Hereinafter, we will learn about the supply of electric energy from the wind power generator (30) to the LED unit (10). The wind power generator (30) and the LED unit (10) are connected in a relationship in which they can slide and rotate (r1), and the electric energy between them can be transmitted and connected by allowing a flexible wire to rotate. However, another method may be used to prevent the wire from being twisted or exposed to the outside. For example, in FIGS. 6 and 7, the conductive member (a11) is installed along the inner surface of the first guardrail (381), and the conductive member (a12) is installed along the inner surface of the second guardrail (382). In addition, correspondingly, the conductive member (a21) is installed along one surface of the fixed band (180), and the conductive member (a22) is installed along the other surface of the fixed band (180). At this time, the conductive member (a21) on one side of the fixed band (180) should take a shape corresponding to each other so that they can slide and rotate (r1) while facing and contacting the conductive member (a11) on the inner side of the first guardrail (381). At the same time, the conductive member (a22) on the other side of the fixed band (180) should take a shape corresponding to each other so that they can slide and rotate (r1) while facing and contacting the conductive member (a12) on the inner side of the second guardrail (382). When the fixed band (180) is interposed in the band fixing groove (383), the counterparts that face and come into contact (face and contact) are the conductive members (a11: a21) and the conductive members (a21: a22), and each transmits different poles (+/-) of electric energy to enable current flow.

The current generated in the wind power generation unit (30) is transmitted by connecting to each of the current-carrying members (a11)(a12) attached to the first and second guardrails (381)(382) of the band fixing unit (380) by wires (not shown). And this current is transmitted and supplied to the LED unit (10) by mutual contact of each of the current-carrying members (a11:a21)(a12:a22). In the LED unit (10), each of the current-carrying members (a11)(a12) attached to the first and second guardrails (381)(382) of the fixed band (180) is connected by wires to the control unit (750)/LED driving device of the LED unit (10). The current of the AC generated by the wind power is converted into DC by directly providing an AC/DC conversion unit (370) such as an inverter in the wind power generation unit (30) and supplied therefrom. The exchange can be sent to the LED driving device of the LED unit (10), the control unit (750), etc. to be converted.

When constructing and installing solar and wind power delineators, depending on the road environment or situation, the structure connected to the solar power generation unit (20) - LED unit (10) - wind power generation unit (30) is installed on a flat surface (horizontal surface), a side surface (vertical surface), or a somewhat inclined surface. At this time, it is necessary to change the structure to correspond to each of these vertical, horizontal, and inclined cases, and for this purpose, it has a structure of a band fixing unit (380) and a fixed band (180). When the fixed band (180) is inserted into the band fixing unit (380), it is blocked by the first and second guardrails (381) (382), so that the fixed band (180) can rotate (r1) in one place without moving out of position. The fixed band (180) can rotate concentrically (r1) with the center of the wind power generator (30) as a virtual rotation axis, thereby providing the required rotation angle (tilt angle) of the LED unit (10) and the solar power generator (20) with respect to the wind power generator (30). That is, the LED unit (10) including the fixed band (180) and the solar power generator (20) coupled to the upper end of the LED unit (10) become one body and simultaneously rotate (r1) by a predetermined angle with respect to the wind power generator (30) including the band fixing member (380) to have a rotation angle.

Afterwards, when the bolt hole (388) on the wind power generation side and the bolt hole (188) on the LED side are aligned and matched, at least one place can be tightened and fixed at the same time with a fixing element (b1) such as a bolt. Through this configuration, installation is very simple, convenient, and easy, and the installed state can be maintained for a long time, so it is durable, and it is also easy to disassemble in reverse order.

In addition, by providing a separation means (187) provided on a conventional watch strap, etc., on the body of the fixed band (180), so that the fixed band (180) can be expanded in the longitudinal direction or separated and released before the fixed band (180) is fastened to the fixed element (b1) or when the fastening is released, the fixed band (180) can be easily assisted in detaching from the first or second guardrail (381) (382). However, since most of the fixed bands (180) are manufactured from the beginning in a state in which they are interposed in the band fixing member (380) and provided to the site, it is convenient to only adjust the required rotation angle and perform the procedure of fixing them with the fixed element during construction. Through this process, during the day when the sun is bright and the weather is good, solar power can be generated while wind power can be used simultaneously or as a supplement, and at night or on cloudy days, wind power can be relied on to supply electricity.
