Abstract

A light emitting diode (LED) table lamp including a base, a support arm, a pivot, and a light emitting device is provided. One end of the support arm is connected to the base, and the pivot is provided at the other end of the support arm. The light emitting device includes a lampshade, a LED light assembly provided at the lampshade, and at least a heat pipe. The lampshade is pivotally connected to the support arm by the pivot, and the heat pipe is provided at the LED light assembly. In addition, an end of the heat pipe is tightly fitted with the pivot.

Claims

1. A light emitting diode table lamp comprising:

a base;

a support arm, wherein one end of the support arm is connected to the base;

a pivot provided at the other end of the support arm;

a light emitting device comprising;

a lampshade pivotally connected to the support arm by the pivot;

a light emitting diode light assembly provided in the lampshade; and

at least a heat pipe, wherein the heat pipe is provided at the light emitting diode light assembly, and one end of the heat pipe is tightly fitted with the pivot.

2. The light emitting diode table lamp according to claim 1, wherein the light emitting diode light assembly further comprises a circuit board, so that the light emitting diode light assembly is provided at one surface of the circuit board, and the heat pipe is provided at the other surface of the circuit board.

3. The light emitting diode table lamp according to claim 1, wherein the material of the pivot and the support arm is metal.

4. The light emitting diode table lamp according to claim 1, wherein the material of the base is metal.

5. The light emitting diode table lamp according to claim 1, the light emitting diode table lamp further comprises a lens provided at the lampshade to make the light emitted by the light emitting diode light assembly uniform.
