1 is a view showing a state in which an independent power source type floodlighting apparatus according to an embodiment of the present invention is installed on a bar type structure.

As shown in the figure, the independent power source type floodlighting apparatus according to the present invention is coupled to cover the side surface of the rod-like structure 100 and irradiates light in the longitudinal direction (i.e., up and down) To give a sense of aesthetics.

Here, the rod-like structure 100 includes all of wires, cables, columns, and the like, and a lighting device according to the present invention can be installed anywhere in a bridge, a building, a building,

An independent power source type floodlighting lighting apparatus according to the present invention includes a first case 200, a second case 300 and an illumination source 400 and includes a first case 200 and an inner side of the second case 300 An attached pad such as a silicon pad can be attached to correct the thickness difference of the rod-like structural body 100. [

Hereinafter, specific configurations of the present invention will be described in detail.

FIG. 2 is a view showing an exploded view of each part of an independent power source type floodlighting lighting apparatus according to an embodiment of the present invention. FIG. Fig.

As shown in the figure, the first case 200 and the second case 300 are disposed to face each other with respect to the rod-like structure 100 and are fixedly coupled to each other while surrounding the rod-shaped structure 100.

Since the first case 200 has a cylindrical inner plate 210 and a hexagonal outer plate 220 and the inner plate 210 and the outer plate 220 are formed in different shapes, It is possible to maximize the current supply efficiency through the power supply 500.

That is, in the case where the inner plate and the outer plate of the first case are formed in the same shape as the conventional products, the energy efficiency is low because the solar cell must be installed according to the shape of the solar cell, Since the inner plate 210 and the outer plate 220 are formed in different shapes, it is possible to maximize the energy efficiency or to have a better aesthetics when installed in the rod-shaped structure.

Like the first case 200, the inner case 310 and the outer case 320 of the second case 300 are different from each other. The inner case 210 of the first case 200, And the inner plate 310 of the inner tube 300 is closely contacted while facing each other.

Since the first case 200 and the second case 300 serve as external landscapes, they are selected in consideration of various factors such as durability, maintenance, economical efficiency, safety, and comfort, and are exposed to sunlight, Since the conditions must be taken into account, waterproofness must be ensured.

Specifically, the surfaces of the first case 200 and the second case 300 are subjected to a waterproof and dustproof design and a special surface treatment for preventing corrosion. For example, the first case and the second case can be applied to the IP67 waterproof and dustproof design, and the IP67 means the dustproof grade 6 and the waterproof grade 7. It means perfect protection against external dust, water depth within 15cm to 1m In waterproof performance for about 30 minutes.

The first case 200 and the second case 300 may be made of any one of aluminum, polycarbonate and ceramics or a combination thereof. And the second case are configured to have an outer shape so that they are formed of a material having good durability and good shape.

The illumination source 400 is installed on the upper and lower plates 230 and 330 and the lower plates 240 and 340 of the first case 200 and the second case 300, A compact diffusing lens, a reflecting plate, a condenser lens, and the like so that light can be radiated in the longitudinal direction of the substrate. The cross-sectional transmission distance of the illumination source 400 is preferably 10 to 15 m.

The seating portions 221 and 321 are formed to cover both the first case 200 and the outer side plates 220 and 320 of the second case 300, (220, 320) so as to maximize the photovoltaic power generation efficiency.

In the case of the conventional product, since the solar battery cell is fixedly attached, it is not easy to install and replace. However, since the solar cell 500 according to the present invention is inserted into the seating portions 221 and 321, It is possible to maximize the solar power generation efficiency because there is no separate fastener or the like.

The solar cell 500 may be a thin film solar cell using a plastic substrate having a high efficiency. The maximum voltage may be about 11 to about 24 V, and the maximum power may be about 80 to about 100 W.

A coupling hole 211 is formed in each of the inner plates 210 and 310 facing the first case 200 and the second case 300 and the first case 200 and the second case 300, A predetermined space 250 is formed inside the first and second cases, and the first case and the second case are coupled to each other on the inner side (inner side).

That is, in the case of a conventional product, both the fastening holes and the solar cell are disposed outside, whereas the outer plates 220 and 320 of the first case 200 and the second case 300, according to the present invention, Only the cell 500 is disposed and the first case 200 and the second case 300 are coupled to each other in the direction of the inner plates 210 and 310.

As described above, the first case 200 and the second case 300 are coupled through the inner fastening holes 211 to prevent the fastening portions from being corroded from external stimuli (rain, wind, sunlight, etc.) And the arrangement efficiency of the solar cell 500 can be increased.

In addition, a plurality of grooves are formed on the inner surface of the solar cell 500 (a portion contacting the seating portion) to induce ventilation, thereby increasing the heat radiation effect. The plurality of grooves may be formed in various shapes such as a longitudinal direction (longitudinal direction) or a lattice shape on the inner surface of the solar cell.

Specifically, the capacity of the battery 600 is obtained by the following equation.

[Mathematical Expression]

Battery capacity (Wh) = (number of days to be relieved + 1 day) x (use strategy amount / day) x 1.1 (margin factor)

For example, in order to emit light for 8 hours a day, the battery 600 can emit light for three days even in a situation in which the daylight is not enough, and (3 + 1) x (20W x 8H / day) x 1.1 = 704 Wh Battery capacity should be available.

The battery 600 is preferably a lithium-ion battery or a lithium-iron (FePO ₄ ) battery.

The control unit 610 controls the state of the illumination source and controls the illumination source from the outside. For example, the control unit 610 can recognize and manage damage / deficiency / failure / abnormality of the illumination source, and can control various sources by controlling the illumination source. In addition, You can turn it on or off.

The communication unit 620 transmits the status information of the illumination source to the outside and transmits the signal transmitted from the outside to the control unit. Through the communication unit 620, the user can remotely control the independent power source type floodlighting apparatus according to the present invention from the outside, and can recognize the state of the lighting apparatus at a time from outside.

The communication unit 620 may be controlled at a short distance using ZigBee or Wi-Fi communication or may be controlled at a long distance using LoRa communication.
