Abstract:
1. A dimmable LED lamp for receiving power from a DC power source to emit light, comprising: a main body, which is hollow, having a conductive portion made of a conductive material, wherein the conductive portion is connected to the DC power source; a DC/DC converter provided in the main body, and electrically connected to the conductive portion of the main body to convert a voltage of the power from the DC power source into a corresponding current; a LED module provided on the main body, and electrically connected to the DC/DC converter to emit light with luminance corresponding to the current received from the DC/DC converter; and the current outputted from the DC/DC converter is varied in accordance with variance of the voltage of the power from the DC power source, which makes the LED module naturally emit light with different luminance accordingly.
