Description

TECHNICAL FIELD [0001] The present invention relates to a lighting system having a lightning forecasting function,

The present invention relates to a lightning protection system capable of predicting a lightning stroke by an electric field generated when approaching thunderclouds.

Lightning is a discharge phenomenon that occurs between clouds and earth. Looking at the frequency of lightning strikes, it is estimated that an average of 130,000 lightning strikes a year even in Korea alone. In recent years, the frequency of lightning has increased due to the effect of global warming, and the intensity of the lightning current accompanying the lightning has also become stronger.

Thunderstorms can cause serious damage to people and property. In the days when lightning rods were not developed in the past, there were also cases where a lightning strike occurred at a facility where city gunpowder was stored and many people lost their lives. When a lightning strike occurs, electricity may flow to people who are directly hit by a lightning strike as well as people nearby.

The lightning rod is a metal rod with a pointed end and is installed in a tall building or a pole to reduce damage to buildings, damage, and human life caused by lightning or lightning.

In recent years, lightning arresters have been installed in tall buildings to dramatically reduce lightning accidents. However, even if a lightning rod exists, a high-voltage current flows in the place where a lightning stroke occurs at the moment of occurrence of a lightning stroke, so it is difficult to completely prevent the occurrence of personal injury.

Therefore, research is being conducted on an alarm system that informs the area where there is a risk of a lightning strike. Especially, a method of releasing a lightning rod, which is likely to drop a lightning bolt, to the surrounding people to escape from the danger area is being studied.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood, however, that the embodiments described below are only for explanation of the embodiments of the present invention so that those skilled in the art can easily carry out the invention, It does not mean anything. In describing various embodiments of the present invention, the same reference numerals are used for components having the same technical characteristics.

1 is a conceptual diagram illustrating a driving mechanism of a lightning protection system 100 according to an embodiment of the present invention.

1, the lightning protection system 100 includes a lightning rod head 110, a light emitting module 200, a lightning rod support 150, a lightning stroke counter (not shown), a grounding unit 140, and the like can do.

The lightning rod head 110 forms a strong electric field when approaching the thunderclouds. The lightning rod head unit 110 includes a projecting portion for sucking light stroke. The spines are mainly made of copper or hot-dip galvanized iron and have a low electrical resistance, so that electricity is well formed.

The thunderstorm starts with a stepwise downward leader from the thunderstorm to the surface. The downward leader carries many electric charges and the electric field increases exponentially on the surface. As a result, the corona discharge begins at a point on the ground, and the streamer and the upward reader are gradually formed to meet the downward leader formed in the thundercloud.

The lightning rod head 110 of the present invention can generate an upward reader capable of attracting the downward leader of the lightning stroke early. As the upward leader progresses, it affects the downward leader, and the upward and downward leaders meet at one point. At this time, there is an electrically energized state between the surface and the thundercloud, and a lightning strike occurs.

The light emitting module 200 is mounted adjacent to the lightning rod head 110. The light emitting module 200 may be mounted on any part of the lightning rod, but it is preferably mounted on a lightning rod head 110 capable of detecting the change of the electric field most strongly.

The light emitting module 200 senses an electric field generated by the thunderstroke before the reader is generated or before the reader generates the light. A person looking at the lightning rod can sense the risk of a lightning strike by seeing the lightning rod shine before the lightning occurs.

The lightning rod support 150 is formed to support the lightning rod head 110. The lightning rod support base (150) is made of an insulating member so as to prevent a current from flowing around when a lightning stroke occurs. The down conductor 122 may be disposed within the lightning rod support 150 or along the outer surface of the lightning rod support 150.

The lightning stroke counter (not shown) is operated by the current flowing through the downward conductor 122 to record the number of lightning strokes.

The grounding portion 140 allows the brain current flowing through the down conductor 122 to flow safely into the ground. The grounding part can be formed by the grounding and can be discharged early by lowering the discharge start voltage, thereby maximizing the earth effect.

The lightning protection system 100 according to the present invention does not emit light normally (a) but emits light (b) when thundercloud approaches.

The lightning protection system 100 includes a lightning rod head 110, a light emitting module 200, a lightning rod support 150, and a down wire 122. The lightning rod head 110 includes a protrusion And an extension extending downwardly from the projection.

The light emitting module 200 may be mounted to surround the outer circumference of the lightning rod head 110. The light emitting module 200 may be in the form of a cylinder surrounding the extension. An insulation member may be disposed on the upper and lower sides of the cylinder so that the light source 220 is not damaged when a lightning storm occurs in the projecting portion. The light source 220 is spaced apart from the extended portion and is not affected by the current flowing in the extended portion.

The extension portion may have a connection portion 121 to which the down conductor 122 is connected. A lightning stroke counter (not shown) may be installed in the connection unit 121 to count the number of lightning strokes.

An insulator 160 may be disposed between the extension and the lightning rod support 150. The insulator 160 prevents the lightning stroke current transmitted through the extension from flowing into the lightning rod support 150.

As shown, the down wire 122 extends along the outer surface of the lightning rod support 150 to the ground. The down conductor 122 is surrounded by the insulating member so that the lightning current does not flow outside the conductor. One end of the down-conductor 122 is connected to the extension and the other end is grounded.

2 is a conceptual diagram for explaining the operation of the light emitting module 200 shown in FIG.

Referring to FIG. 2, the light emitting module 200 may be formed to surround the extended portion of the lightning rod head 110.

The extension portion may include a lead wire 111 connected to the projection portion and receiving a lightning current, and an insulation layer 112 surrounding the lead wire 111 so that the lightning current does not flow to the outside.

The light emitting module 200 includes a light source 220 disposed apart from the extension portion. The light source 220 includes a light emitting element that emits light by an electric field. The light emitting device senses an electric field generated in the lightning rod head 110 by a thundercloud approach and emits light. This allows people around the lightning rod to predict the risk of a lightning strike on the lightning rod.

According to another embodiment of the present invention, the light source 220 of the light emitting module 200 may include a plurality of light emitting devices. Each light emitting element can be formed to emit light with an electric field of different intensity. For example, when the electric field intensity is A (V / m), the first light emitting device emits light and the second light emitting device does not emit light. Further, each light emitting element may be formed to emit light of a different color.

It becomes possible to predict the degree of lightning risk by these light emitting elements. For example, when an electric field around the lightning rod is formed by approaching thunderclouds, when the electric field intensity is low, the lightning rod may emit yellow light and may be formed to emit red light when the electric field intensity becomes stronger and exceeds a specific value . A person looking at the lightning rod can confirm that the color emitted by the lightning rod changes, and it is possible to grasp the degree of the risk of lightning.

A reflective plate 221 may be disposed between the light emitting device and the extension. The reflection plate 221 reflects light generated from the light emitting device to the outside to increase the luminous efficiency.

According to another embodiment of the present invention, a plurality of light emitting elements are disposed apart from each other, and each reflection plate 221 is arranged to surround each light emitting element. For example, the reflection plate 221 may be disposed so as to surround the light emitting element by drawing a parabolic surface, so that the light of the light emitting element is emitted to the outside without spreading.

A polar gas may be filled in the space 210 between the light emitting device and the extension part. When an electric field is formed by the thunderclouds, a polarity is generated in a space between the light emitting device and the extension part, and light emission of the light emitting device can be assisted.

The insulator 160 may be filled in the space 210 between the light emitting device and the extension part or may be formed in a vacuum if necessary.

3 is a conceptual diagram illustrating a configuration of a light emitting module 200 according to an embodiment of the present invention.

Referring to FIG. 3, the light emitting module 200 includes a sensor unit for sensing a change in the electric field around the lightning rod head, an energy conversion unit for converting electric energy into light energy based on the electric field change, And a display unit for informing the possibility of occurrence of a lightning stroke by diverging. This distinction is for the sake of convenience of description, and it is also possible that one component can perform the functions of the sensor unit, the energy conversion unit and the display unit together without actually distinguishing them.

4 is a flowchart illustrating a lightning forecasting method according to an embodiment of the present invention.

Referring to FIG. 4, when the thundercloud approaches, an electric field is generated near the lightning rod head. A light emitting module 200 that emits light due to an electric field change is mounted on the lightning rod head 110. The light emitting module 200 emits light when an electric field is generated due to approach of thundercloud. People can sense that there is a risk of a lightning strike on the lightning rod when the lightning rod begins to glow and escape the danger zone.

In other words, in the present invention, an electric field is formed around the lightning rod head by approaching thundercloth, a step in which charge flows in the light emitting module 200 mounted on the lightning rod head by an electric field, The possibility of the lightning can be predicted through the step of informing the possibility of the lightning.

According to the lightning protection system 100 having the lightning forecasting function according to at least one embodiment of the present invention, an element emitting light by an electric field is mounted around the lightning rod head, and the lightning rod illuminates when the thundercloud approaches . This allows people around the lightning rod to identify the risk of a lightning strike and escape from the danger zone.

Further, the light source 220 installed in the lightning rod does not need to supply additional power to the light source 220 because it emits light by the electric field of the thunderclouds. Therefore, it is possible to prevent the light source 220 from being damaged by the lightning stroke current even if the lightning stroke occurs.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
