Description

SOLAR STREET LIGHT
Technical Field
The present invention relates to a solar street light, and more particularly to a solar street light that is easily installed and repaired, capable of assembling various rotating posts and screen panels to various lamp posts, and fixing batteries to a separate fixed frame, and fixing the fixed frame inside the lamp post at a predetermined height, thereby preventing the batteries from being submerged by a flood, and simply installing and replacing the batteries.
Background Art In general, a solar street light is composed of a solar cell producing electricity using the sunlight, a battery storing the electricity produced from the solar cell, an illuminator supplied with the electricity from the battery to emit light, and a post supporting the solar cell, the battery, and the illuminator.
The solar street light constructed in this way stores the electricity produced from the solar cell in the battery, and then supplies the electricity from the battery to the illuminator, thereby driving the illuminator.
The solar cell produces electricity using the sunlight in the daytime, and then sends the produced electricity to the battery. The electricity stored in the battery is supplied to the illuminator in the nighttime and drives the illuminator. Thereby, a lamp of the illuminator emits light, which is illuminated downward. As a result, the surroundings of the post can be brightly illuminated.
Meanwhile, such a solar street light is disclosed in Korean Utility Model Registration Publication No. 20-
0389289 (titled "Illumination rendering system of street light using solar cell and GPS") filed by the present applicant and registered.
As illustrated in FIGS. 1 and 2, the illumination rendering system 10 as mentioned above includes a lamp post 11 that has a circular or polygonal shape, a base 11-1 formed at the bottom thereof, a circular rotating axle 11-3 protruding at an upper end thereof, and a cabinet 11-5 in which a storage battery 15 is housed; a rotating post 12 that is formed to rotate about rotating axle 11-3 of the main post 11 at an angle of 360 degrees; a screen panel 13 that has a circular or polygonal shape, a light collector 16 charging the storage battery 15 and attached on a top surface thereof, a global positioning system (GPS) antenna 17 attached on the top surface thereof, a reflector 13-1 formed at a bottom thereof, and a support 13-3 slantedly fixed to a circumference of the rotating post 12; and an illumination rendering device 14 that has opposite open ends in a quadrangular or circular shape so as to illuminate the screen panel 13 and a roadway by means of a plurality of light emitting diodes (LEDs) having super high brightness, and is fixed to an upper end of the lamp post 11 by means of a bracket 11-7 so as to allow the illumination rendering device 14 to rotate left and right. Among them, the illumination rendering device 14 includes a body 14-1 that has opposite open ends in a quadrangular or circular shape so as to illuminate the screen panel 13 and a roadway by means of a plurality of LEDs having super high brightness, and is fixed to an upper end of the lamp post 11 by means of a bracket 11-7 fixed, and is formed with a hollow fixture 14-2 coupled with the bracket 11-7 in the middle thereof, and a control module 20 installed therein; an advertisement illumination panel 14-3 that is mounted with the plurality of red, green, and blue LEDs 14-4 having super high brightness, and provided inside the upper end of the body 14-1; and a roadway illumination panel 14-5 that is mounted with the plurality of white LEDs 14-6 having super high brightness, and provided inside the lower end of the body 14-1.
However, when the storage battery installed in the lamp post should be replaced with a new one due to expiration of its lifespan in the conventional solar street light, the lamp post of the solar street light should be separated from the foundation buried in the ground. For this reason, the replacement requires much time and expense.
Further, when the screen panel has a wide area, its supporting part shows a tendency to be easily damaged by strong winds.
In addition, an angle of the screen panel is not adjusted, and the illumination rendering device is restricted by a rotating direction. Hence, it is difficult to install the screen panel and the illumination rendering device so as to sufficiently exert their functions.

Hereinafter, the installation and operation of the solar street light according to the present invention will be described in detail with reference to the accompanying figures.
First, the ground is excavated at a position where the solar street light 100 is installed, and a concrete block 111 is set in the ground.
In this state, the base panel 211 of the foldable member 210 is coupled to the concrete block 111. To this end, the anchor bolts 110 protruding from the concrete block 111 are inserted into and pass through the first anchor bolt holes 213, and then are fastened by the nuts 130.
Meanwhile, the fixed frame 500 to which the batteries 101 are fixed is inserted into the lamp post 200 through the second through hole 217 of the lamp post 200. Then, the bolt holes 511 of the fixed frame 500 is fitted to the fixing bolt 270 of the lamp post 200, and the fixing bolt 270 are fastened by a nut (not shown) through the first repairing hole 240, thereby fixing an upper end of the fixed frame 500. Subsequently, the fixing bolt 120 is fastened to the bolt fixed plate 280 through the second repairing hole 250, thereby fixing a lower end of the fixed frame 500.
Then, the covers 260 are coupled to the first and second repairing holes 240 and 250, respectively.
Next, the band bracket 600 is fastened around the bracket recess 230 formed on the outer circumference of the upper portion of the lamp post 200 using the fastening bolt 120, thereby fixing the LED lamp 107. At this time, the band bracket 600 can position the LED lamp 107, and employ one or two LED lamps 107 according to a choice.
When the fixation of the band bracket 600 is complete, the rotating post 300 is inserted into and fixed to the stepped upper end 220 of the lamp post 200. Here, the rotating post 300 and the screen panel 400 can be installed in a desired type according to the choice of a user.
When the rotating post 300 is inserted, the nuts 311 of the rotating post 300 are bolted by the bolts 120, thereby fixing the rotating post 300 to the lamp post 200. At this time, in consideration of a direction of the sunlight, the rotating post 300 is rotated before being fixed, and the first hinge plug 332 and the second U-shaped hinge brackets 423 are pivoted, thereby the position of the screen panel 400 is selected.
When the fixation of the rotating post 300 is complete, the lamp post 200 is lifted by equipment such as a crane truck.
