An LED spotlight includes a base and lampshade. The base includes a power connecting portion, a heat dissipating portion and circuit board which are connected to the power connecting portion; and an LED unit disposed at the circuit board for emitting first and second light. The center-to-edge distance of the circuit board is defined as a first distance. The LED unit is separated from the center of the circuit board by a second distance. The second distance equals at least 1/10 of the first distance. The lampshade includes an opaque pipe and convex lens. The pipe has one end connected to the heat dissipating portion and the other end connected to the convex lens. The first light penetrates the convex lens to form a first light-emitting area. The second light reflects off the inner wall of the pipe and penetrates the convex lens to form a second light-emitting area.
