An exemplary light emitting diode (LED) lamp includes a lamp body, an LED module and a switching member. The LED module is mounted on the lamp body and includes a plurality of first LED components emitting a first light with a first color temperature and a plurality of second LED components emitting a second light with a second color temperature. The switching member is mounted around the lamp body and can be operated to cause the LED lamp to work in different modes. In the different modes, different numbers of the first and second LED components are driven to emit light with different color temperatures.
