PURPOSE: An LED lamp is provided to improve the illuminance and intensity of light by arranging a plurality of LEDs in the outer surface of a hemisphere. CONSTITUTION: A shield(6) has a space in order store a power circuit substrate. A heat dissipating part(12) includes a heat radiation fin(10) which is horizontally arranged along a vertical channel(18). A through-hole(24) is horizontally formed in order to be communicated with the vertical channel. A thicker part(22) is formed in the lower hemisphere part of the heat dissipating part towards the outer circumference of the vertical channel. A plurality of LEDs(32) are attached to an LED substrate.
