Abstract
An LED lamp includes a base, at least first and second heat sinks, and at least first and second LED modules. The first heat sink includes a first heat absorbing surface and a first mounting surface which is mounted to the base, and defines axially a first through hole. The second heat sink includes a second heat absorbing surface and a second mounting surface which is mounted to the base. The second heat sink is received in the first through hole of the first heat sink. The second heat sink has a height greater than a height of the first heat sink whereby the second heat absorbing surface extends out of the first heat sink. The first and second LED modules are mounted on the first and second heat absorbing surfaces, respectively.
Claims13
An LED lamp comprising:
- a base;
- a first heat sink comprising a first heat absorbing surface at one end and a first mounting surface at another end opposite to the first heat absorbing surface, the first mounting surface being mounted to the base, the first heat sink defining axially a first through hole, the first through hole extending from the first heat absorbing surface to the first mounting surface;
- a second heat sink comprising a second heat absorbing surface at one end and a second mounting surface at another end opposite to the second heat absorbing surface, the second mounting surface being mounted to the base, the second heat sink being received in the first through hole of the first heat sink, the second heat sink having a height greater than a height of the first heat sink whereby the second heat absorbing surface extends out of the first heat sink;
- a first LED module mounted on the first heat absorbing surface;
- and
- a second LED module mounted on the second heat absorbing surface.
