<p>The present invention relates to a flashlight. In order to improve heat transfer efficiency and therefore to quickly and efficiently release heat generated by LEDs to the outside even if the LEDs as a light source are installed to emit light in the lateral direction as well as in the forward direction. The flashlight includes a body part containing a power source part, has a heat-releasing column with air-flow paths on one end of the body part; and enables a PCB equipped with LEDs to be installed on the heat-releasing column, thereby releasing heat generated by the LEDs to the outside through the air-flow paths. The PCB (300) comprises: a forward PCB (310) installed on the top of the heat-releasing column (200); and a lateral PCB (320) installed on the outer side of the heat-releasing column (200).</p> |
