Solar cell street lights with cooling function

A solar cell street lights with a cooling device for streetlight head portion, where a battery (1) and a light emitting diode (LED) module are accommodated together and a solar panel is mounted, comprising:

• a vertical pillar (100) fixed to a ground at a lower end of the vertical pillar (100) and having a first hollow portion (101) formed along it's body and an air inlet (102), through which an external air is introduced, communicated with the first hollow portion (101);
• a hollow mounting rod (110) obliquely connected upward from one side of an upper end portion of the vertical pillar (100) and having a second hollow portion (112) communicated with the first hollow portion (101) and formed along the body of the hollow mounting rod (110);
• a lower housing (120) having a receiving portion (121) for receiving the battery (1) formed on one side of the lower housing (120), a mounting hole (122) for mounting the LED module (700) formed on the other side of the lower housing (120);
• and one end connected to the hollow mounting rod (110) to be communicated with the second hollow portion (112);
• and
• an upper housing (130) mounted on an upper surface portion of the lower housing (120) to form an internal space (A) together with the lower housing (120) and having one end connected to the hollow mounting rod (110) to be communicated with the second hollow portion (112), an air outlet (131) for discharging air introduced through an air inlet (102), and a mounting plate (2), on which the solar panel is mounted and fixed, formed on an outer surface of the upper housing (130);
• wherein the external air introduced through the air inlet (102) passes through the vertical pillar (100), the hollow mounting rod (110), and the receiving portion (121), and is discharged through the air outlet (131);
• and
• wherein the receiving portion (121) comprises an opening (121a) for insertion and removal of the battery (1) formed at a lower portion of the receiving portion (121);
• a side wall (121b) formed around a lateral circumference of the receiving portion (121);
• a plurality of seating ribs (121c) formed on a floor surface of the receiving portion (121) where the battery (1) is placed;
• a through-hole (121d) communicating with the internal space (A) formed between the plurality of seating ribs (121c);
• and a cover (121e) for opening and closing the opening (121a), so that it allows a heat released from the battery (1) to be discharged through the through holes (121d) and the air introduced from the hollow mounting rod (110) to flow near the through-hole (121d), thereby carrying the battery's heat with the air and eventually being discharged through the air outlet (131).
