A self-powered LED flashlight is provided. The self-powered LED flashlight comprises: a body (110) having an insertion hole (111) formed in the longitudinal direction therein; multiple thermoelectric power generation devices (120) arranged around the inner surface of the insertion hole; a cooling body (130) inserted into the center of the thermoelectric power generation devices and having a cooling hole (131) therein to circulate air in the longitudinal direction; a rechargeable battery (140) mounted in the cooling hole (131) and connected to the thermoelectric power generation devices (120); a top body (150) installed on the upper portion of the body (110); an LED lamp (160) mounted in the top body (150) and connected to the thermoelectric power generation devices (120) to receive power by the operation of a switch (112) formed on one side of the body (110); a lens (170) installed on the upper portion of the top body (150); and a lid (180) installed on the bottom of the body (110). The thermoelectric power generation devices can be operated by a temperature difference between air temperature and the hand of a user gripping the flashlight. The flashlight according to the present invention does not necessarily require any recharging processes or batteries, thereby improving efficiency and convenience. |
