LED lamp
First Claim
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; and
a light board connected to the base of the passive heat dissipating element and comprising LED chips in an array arrangement electrically connected to the power source;
wherein a chamber of the lamp shell is formed with a first heat dissipating channel, the first heat dissipating channel has a first air inlet at a first end of the lamp shell, a second end of the lamp shell has at least a heat dissipating hole;
wherein a second heat dissipating channel is formed in the heat sink and between the fins and base, the second heat dissipating channel has a second air inlet, such that air flows from outside of the LED lamp into the second air inlet and passes through the second heat dissipating channel, and flows out from spaces between every adjacent two of the fins.

Abstract
An LED lamp includes: a lamp shell; a passive heat dissipating element having a heat sink, and the heat sink including fins and a base and connecting to the lamp shell; a power source disposed in the lamp shell; and a light board connecting to the heat sink and including LED chips electrically connected to the power source. A chamber of the lamp shell is formed with a first heat dissipating channel. The first heat dissipating channel has a first air inlet at an end of the lamp shell. Another end of the lamp shell has a heat dissipating hole. A second heat dissipating channel is formed in the fins and base. The second heat dissipating channel has a second air inlet. Air flows into the second air inlet, passes through the second heat dissipating channel and flow out from spaces between every adjacent two of the fins.
