Abstract
An exemplary LED lamp includes a heat sink, and an LED module mounted on the heat sink. The heat sink includes a base, a receiving tube extending upwardly from a first face of the base, and a plurality of fins extending outwardly from an outer circumference of the receiving tube. The LED module is mounted a second face of the base. A plurality of through tunnels are defined in the base. The through tunnels extend through the base from the first face to the second face of the base. Each through tunnel communicates with an air passage between two neighboring fins.
Claims16
An LED lamp comprising:
- a heat sink comprising a base comprising a first face and a second face opposite to the first face, a receiving tube extending upwardly from the first face of the base, and a plurality of fins extending outwardly from an outer circumference of the receiving tube, the fins directly connecting to the first face of the base;
- an LED module mounted on a second face of the base;
- and
- a plurality of through tunnels defined in the base and extending through the base from the first face to the second face of the base.
An LED lamp comprising:
- a heat sink comprising a base having a first face and a second face opposite to the first face, a receiving tube extending upwardly from the first face of the base, and a plurality of fins extending outwardly from an outer circumference of the receiving tube, a central area of the second face of the base being depressed inwardly, whereby an annular mounting portion is formed along an outer periphery of the second face of the base, and a receiving portion is defined at the central area of the second face of the base, the fins being arranged radially relative to the receiving tube;
- an LED module mounted the second face of the heat sink;
- and
- a plurality of through tunnels defined in the heat sink and extending through the heat sink from the first face to the second face of the heat sink.
