Zusammenfassung:	An embodiment of the utility model provides a lighting device which comprises a lighting module (100), a radiating component (200) and a base (300). The radiating component (200) is thermally coupled with the lighting module (100). The base (300) can power the lighting module (100). The radiating component (200) comprises at least a first chamber (210) and a second chamber (220) which surround the lighting module (100) and/or the radiating component (200) and are in air communication with each other, wherein the first chamber (210) is provided with at least one air exchanging port communicated with the atmosphere, and the second chamber (220) is provided with at least one different air exchanging port communicated with the atmosphere. The lighting device has the advantages that the radiating performance of the lighting component is increased evidently, and the lighting device is allowed to use the light module with higher power.
