Abstract

An LED lamp, comprising a base; a lamp envelope coupled to the base; a support module accommodated in the lamp envelope, a first inner cavity being formed between the support module and the lamp envelope, the first inner cavity containing therein a first gas medium; a driver module accommodated in the first inner cavity and coupled to the support module; and an LED inner vessel accommodated in the first inner cavity and coupled to at least one of the support module and the driver module, a sealed second inner cavity being formed within the LED inner vessel, and the second inner cavity containing therein a second gas medium and an LED light source module.

First claim

The invention claimed is:

1. A LED lamp, comprising:
a base configured for connection to a power source;
a lamp envelope coupled to the base;
a support module having a bottom end electrically connected to the base and a top end comprising at least one metal pin and at least one fixing device;
a first inner cavity being formed between the support module and the lamp envelope, the first inner cavity containing therein a first gas medium;
wherein the at least one fixing device is configured for filling the first inner cavity and charging the first gas medium;
a driver module (i) being accommodated in the first inner cavity and (ii) having a top end connected to a LED inner vessel accommodated in the first inner cavity and a bottom end mounted to the support module; and
a closed second inner cavity being formed within the LED inner vessel the second inner cavity containing therein a second gas medium and a LED light source module;
wherein, the driver module is mounted and secured to the support module by (i) coupling the at least one metal pin to the driver module and (ii) inserting the at least one fixing device into a fixing hole of the driver module; and
wherein, the driver module is disposed outside of the second inner cavity.

2. The LED lamp according to claim 1 , wherein the support module is configured to supply electricity to the driver module via the at least one metal pin.

3. The LED lamp according to claim 1 , wherein the LED inner vessel comprises at least one metal pin, one end of the metal pin coupled to the LED light source module and the other end coupled to the driver module.

4. The LED lamp according to claim 1 , wherein the first gas medium and the second gas medium have the same composition and comprise at least one of helium, hydrogen.

5. The LED lamp according to claim 1 , wherein the first gas medium and/or the second gas medium comprises helium and oxygen, wherein a volume ratio between helium and oxygen is (2.5˜50):(50˜97.5).

6. The LED lamp according to claim 1 , wherein the first gas medium comprises at least one of helium and hydrogen, and the second gas medium comprises helium and hydrogen, wherein hydrogen is released from a hydrogen releasing agent in the presence of electromagnetic waves.

7. The LED lamp according to claim 1 , wherein the LED light source module comprises a support unit and a LED chip mounted on the support unit.

8. The LED lamp according to claim 1 , wherein the LED inner vessel comprises a shell made of a material selected from transparent hard glasses or transparent quartz glasses, and the shell is shaped as a sphere, an ellipsoid, a cube, or a cuboid.

9. The LED lamp according to claim 1 , wherein the fixing device further comprises a charging and exhausting port for filling the first inner cavity and charging the first gas medium.

10. The LED lamp according to claim 3 , wherein the metal pin is configured to fix the LED inner vessel to the driver module.

11. The LED lamp according to claim 7 , wherein the support unit comprises at least one support plate or at least one support column.

12. The LED lamp according to claim 7 , wherein, the second gas medium comprises hydrogen and helium and the supporting unit is made of a material selected from glasses, ceramics, metals or sapphires.

13. The LED lamp according to claim 7 , wherein, the second gas medium comprises hydrogen and oxygen and the supporting unit is made of a material selected from glasses, ceramics, metals or sapphires.

14. The LED lamp according to claim 7 wherein, the second gas medium comprises oxygen and helium and the supporting unit is made of an organic material or a metal-organic compound material.
