Abstract

A LED lamp system including an electric linker, a heat conducting liquid, a hollow cooling system with an outer surface, a hollow chamber through which a heat conducting liquid is located, and a hollow cavity separate from the hollow chamber, at least one LED, an interface connected to the hollow cooling system and to the at least one LED, and a power supply connected between the electric linker and the interface.

Claims

1. A LED lamp system comprising:

an electric linker for a lamp socket;

a heat conducting liquid;

a hollow cooling system with an outer surface, a hollow cavity, and a hollow chamber through which the heat conducting liquid is located with a majority of the hollow chamber in contact with the outer surface, wherein the hollow chamber defines an outer periphery of the lamp system that surrounds the hollow cavity;

at least one LED being outside of the hollow cooling system;

an interface connected to the hollow cooling system and to the at least one LED; and

a power supply connected between the electric linker and the interface.

2. The LED lamp system according to claim 1, further comprising a lampshade connected to cover the at least one LED.

3. The LED lamp system according to claim 2, wherein the lampshade comprises glass and/or polymethyl methacrylate.

4. The LED lamp system according to claim 1, wherein the hollow cooling system is connected air-tightly with the interface.

5. The LED lamp system according to claim 1, wherein the heat conducting liquid is conductive and/or non-conductive.
