An LED (light emitting diode) lamp includes a baseboard ( 10 ), an LED ( 30 ), a holder ( 20 ), a first lens ( 40 ), and a cylinder lens ( 42 ). The LED is set on the baseboard, the holder is set on the baseboard surrounding the LED, the first converging lens is mounted in the holder and located above the LED, and the cylinder lens is mounted in the holder above the first lens. In an alternative embodiment, the first lens and the cylinder lens are replaced by a single curving cylinder lens ( 44 ). The LED lamp can converge the intensity of illumination and can flatten the range of illumination.
