Abstract
An LED lamp includes LED chips, an axle, and a lampshade. The LED chips are mounted on surface of the axle. The axle extends across the lampshade. A heat pipe is installed inside the axle for transferring the heat generated by the LED chips to exterior of the lampshade and obtaining a better heat dissipation.
