DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(23) The street lights assembly of the present invention is configured to use a natural airflow path to cool a solar panel, a LED module, and a battery, thereby preventing reduced power output from the solar panel due to heat, battery degradation, and shortening of the LED's lifespan caused by high temperatures.

(24) Referring to FIG. 1 through FIG. 4, the street lights assembly 20 of one embodiment of the present invention integrates the battery and the LED module (700) within a single housing, with the solar panel (not shown) mounted and fixed on top of the housing.

(25) The street lights assembly of one embodiment of the present invention includes a vertical pillar (100), a mounting rod (110), a fan member (300), a lower housing (120), and an upper housing (130).

(26) The vertical pillar (100) is fixed to a ground at the lower end thereof and has a first hollow portion (101) formed along its body and air inlets (102), through which external air is introduced, communicated with the first hollow portion (101).

(27) The mounting rod (110) is obliquely connected upward from an upper end portion of the vertical pillar (100) and has a through-hole (111) communicating with the first hollow portion (101) and a second hollow portion (112) formed along its body.

(28) At the lower end portion of the vertical pillar (100), it is provided with a blocking member (30) that blocks both sides and the upper portion of the inlet (102) and a bottom member (31) that blocks the lower portion of the inlet (102) and includes multiple through-holes (31a).

(29) These through-holes control the airflow entering via the inlet (102), thereby adjusting the cooling effect at the top of the street lights depending on the season (summer or winter). They also prevent external foreign substances from entering the inlet (102), thereby preventing contamination thereof.

(30) In the meantime, a collection member (40), which surrounds the periphery of the bottom member (31), has an open top and is formed in a tapered shape that is wider at the top and narrower at the bottom, with a drainage hole (41) formed at the lower end. When snow accumulates, it is collected in the collection member (40) and blocks the through-holes (31a) of the bottom member (31). When the snow melts, the water is discharged through the drainage hole (41), thereby opening the through-hole (31a). As such, the through-holes (31a) are opened or closed in response to winter weather conditions.

(31) The lower housing (120) includes a first receiving portion (121) formed on one side thereof to receive the battery, a second receiving portion (123) formed below the first receiving portion (121), where the PCB is received, a mounting hole (122) for mounting a LED module (700) formed on the other side, and one end connected to the mounting rod (110) to be communicated with the second hollow portion (112).

(32) The upper housing (130) is mounted on an upper surface portion of the lower housing (120) to form an internal space (A) together with the lower housing (120). One end of the upper housing (130) is also connected to the mounting rod (110) to be communication with the second hollow portion (112). An outlet (131) is formed to discharge the air entering through the first and second hollow portions (101 and 112). A solar panel (2) is mounted and fixed on an upper surface of the upper housing (130).

(33) In the meantime, a hollow air conduit (500) is arranged parallel to the vertical pillar (100).

(34) The hollow air conduit (500) draws the external air from a lower portion thereof and is connected to the second receiving portion (123). A plurality of air passage pipe (129), through which external air is supplied, are arranged in the second receiving portion (123) via a connection tube (520) and a connection hose (521) that are connected to the upper end of the air conduit (500).

(35) The external air introduced through the air conduit (500) is discharged via the air passage pipes (129), thereby cooling the PCB received in the second receiving portion (123).

(36) Meanwhile, external air entering the first and second hollow portions (101 and 112) passes through the vertical pillar (100), the mounting rod (110), and the first receiving portion (121) and then, is discharged through the outlet (131), thereby cooling both the battery and the solar panel.

(37) Referring to FIG. 4, FIG. 7, FIG. 8, and FIG. 15, an air guide (140) is detachably coupled adjacent to the first receiving portion (121) and guides the air introduced from the mounting rod (110) to the outlet (131).

(38) The air guide (140) includes a top plate (141) facing the opening (121a) of the first receiving portion (120), a pair of side plates (142) formed to face each other at edges of the top plate (141), a plurality of air pipes (143) coupled at both ends to the side plates (142) and through which the air introduced from the mounting rod (110) passes, and an arc-shaped guide plate (144) extending from the side plates (142) to guide the air, that has passed through the air pipes (143), toward the outlet (131).

(39) The air guide (140) configured as described above guides external air introduced through the mounting rod (110) toward the arc-shaped guide plate (144) via a plurality of air pipes (143), so that the air is discharged to the outside through the outlet (131) of the upper housing (130) and the air discharged through the outlet (131) cools the solar panel.

(40) Meanwhile, among the multiple air pipes (143), at least one air pipe (143a) is disposed to pass through the arc-shaped guide plate (144) and extends over the upper side of the LED module (700), thereby cooling the heat generated from the LED module (700).

(41) Referring to FIG. 9, the heat dissipation block (600), which contacts the LED module (700), is connected to the air pipe (143a) to improve cooling performance.

(42) Meanwhile, another solar panel (2) is mounted on the other side of the vertical pillar (100), thereby increasing the power generation. By arranging the solar panels (1 and 2) on both sides of the vertical pillar (100), the streetlight can be stably erected.

(43) As shown in FIG. 4, FIG. 6, and FIG. 7, the first receiving portion (121) includes an opening (121a) for inserting or removing the battery, which also communicates with the internal space (A). A heat dissipation plate that surrounds at least a portion of the battery, is built therein, so that the heat emitted from the battery is transferred to the heat dissipation plate (124) and the air, which is introduced via the first and second hollow portions (101, 112), passes close to the heat dissipation plate (124) and is discharged through the outlet (131) together with the heat emitted from the battery.

(44) Referring to FIG. 1, a fan member (300) that rotates by natural wind is mounted on the mounting rod (110). The street lights assembly according to one embodiment of the present invention includes a generator (not shown) that generates electricity by the rotation of the fan member (300), a protective member (not shown) that surrounds the battery and has a heating wire that receives electric energy from the generator and generates heat, a sensor member that senses the heating temperature of the battery, and a switch that selectively supplies electric energy generated from the generator to the battery or the heating wire according to the sensing temperature of the sensor member.

(45) Referring to FIG. 16, the fan member (300) includes an upper rotating plate (301) having an inclined surface (301a) and a drainage hole (301b) connected to the upper end of a rotating shaft (305), a lower rotating plate (302) having an inclined surface (302a) and a drainage hole (302b) connected to the lower end of the rotating shaft (305), a plurality of side blades (303) for interconnecting the upper rotating plate (301) and the lower rotating plate (302) arranged at regular intervals, and a plurality of inclined blades (304) having both ends fixed to the mutually adjacent side blades (303) and arranged in an inclined manner up and down.

(46) The fan member (300) as described above rotates smoothly when wind or snow hits the inclined surfaces (301a and 302a) and the side blades (303), and in particular, when rainwater falls on the inclined blades (304), the rotation of the fan member (300) becomes more smoothly.

(47) This wind-powered generation system helps to maintain battery warmth in winter and minimize overcooling, thereby preventing a decrease in the power generation capacity of the battery, while also providing auxiliary charging to the battery.

(48) Meanwhile, the street lights assembly of one embodiment of the present invention may be provided with an alarm member that generates an alarm sound, high frequency or low frequency, when a bird approaches the upper housing (130), thereby preventing the approach of birds and preventing contamination of the solar panel by excrement so as to improve power generation efficiency thereof.

(49) In addition, a convex mirror may be placed on the edge of the upper housing (130) to prevent birds from approaching, and a reflective sticker can be attached to the blade of the fan member (300) to prevent birds from approaching.

(50) Referring to FIG. 1 to FIG. 5, the street lights assembly is also equipped with a nozzle (510) connected to the connection tube (520), which blows external air from the bottom of the air conduit (500) toward the solar panel. This improves power generation efficiency by removing foreign substances such as sand that contaminate the solar panels through ventilation.

(51) Meanwhile, referring to FIG. 1 and FIG. 10a to FIG. 10e, the streetlight assembly of one embodiment of the present invention has an opening and closing means for opening and closing the through-hole (111).

(52) The opening and closing means includes a rotating cylinder (150) rotatably connected to the mounting rod (110) and having with an opening (151) formed to open the through-hole (111), an actuation lever (152) connected to the rotating cylinder (150) at one end thereof, and an actuator (155) connected to the other end of the actuation lever (152), which drives the lever's movement, so that the rotating cylinder (150) rotates according to the operation of the actuator (155) to open or close the through-hole (111).

(53) The actuator (155) can operate automatically based on weather conditions or be remotely controlled from the ground.

(54) The above-described opening and closing means opens and closes a path that supplies the external air to the internal space (A) depending on the area where the streetlight is installed, thereby controlling the cooling state of the streetlight components (battery, LED, solar panel).

(55) FIG. 11 to FIG. 14 illustrate another embodiment of the present invention. As shown, a pair of solar panels are arranged in a roof shape, enabling long-term charging in response to changes in the angle of incidence of sunlight due to the Earth's rotation and revolution.

(56) As shown in FIG. 14, the upper housing (130) includes a first inflow groove (132) that is formed on an outer surface thereof and through that rainwater flows therein through the gap between the solar panels, a collection groove (133) formed to store the rainwater flowing in through the first inflow groove (132), and a second inflow groove (134) formed at an edge thereof to allow an external air to flow therein.

(57) These features allow the collected rainwater in the collection groove (133) to evaporate and simultaneously allow the external air through the second inflow groove (134), thus enhancing the cooling efficiency of the solar panel (1).

(58) According to the present invention described above, the street lights assembly of the present invention improves the natural wind path using as the vertical pillar (100), the mounting rod (110), the air passage pipe (129), the air guide (140), the outlet (131), and the air pipe (143) to cool the PCB, the solar panel, the LED module, and the battery, thereby preventing the reduction in the power generation of the solar panel due to the high temperature of direct sunlight, the deterioration of the battery performance due to the high temperature, and the shortening of the lifespan of the LED.

(59) Additionally, the present invention uses wind power generation to keep the battery warm during winter and reduce overcooling, thus preventing performance drops and allowing for auxiliary charging of the battery.

(60) The present invention also generates alarm sounds to deter birds, preventing contamination of the solar panel by bird droppings. Moreover, it uses natural ventilation to effectively remove foreign substances such as sand and dust.

(61) While the present invention has been described with respect to the specific embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims.
