1. An LED (light emitting diode) lamp comprising:

  • a lamp shell;

    a passive heat dissipating element having a heat sink connected to the lamp shell, wherein the heat sink comprises fins and a base;

    a power source disposed in the lamp shell;

    a light emitting element connected to the base of the heat sink of the passive heat dissipating element and comprising LED chips electrically connected to the power source;

    a first channel defined in a chamber of the lamp shell for dissipating heat generated from the power source while the LED lamp is working; and

    a second channel defined in the heat sink and between the fins and the base for dissipating the heat of the heat sink, which is generated from the LED chips and transferred to the heat sink;

    wherein the first channel comprises a first end on the light emitting element to allow air flowing from outside of the LED lamp into the chamber, and a second end on the upper portion of the lamp shell to allow air flowing from inside of the chamber out to the LED lamp;

    wherein the second channel comprises a third end on the light emitting element to allow air flowing from outside of the LED lamp into the second channel, and flowing out from spaces between every adjacent two of the fins;

    wherein the light emitting element further comprises an aperture communicating simultaneously with both the first channel and the second channel by connecting with the first end of the first channel and the third end of the second channel.
