Abstract: An LED lamp includes a lamp base, a transparent shell on the lamp base, a lamp unit consisting of an electric circuit board and a plurality of LED, and a transparent cap. The transparent shell is provided with an annular resting edge in an inner annular wall for the lamp unit to position thereon. The lamp unit is connected electrically with the lamp base, and the transparent cap is positioned on the transparent shell. Then the light of the LED lamp shines forward and sidewise through the transparent shell and the transparent cap to a comparatively large range.
