Abstract
A lamp includes a lighting module and a lamp base. The lamp base includes a base unit. The base unit includes a first base element and a second base element. The first base element includes a plurality of first channels. The second base element includes a plurality of second channels that are in fluid communication with the second channels, respectively. The thermal conductivity of the second base element is lower than that of the first base element. The lighting module is disposed on the first base element. During operation of the lighting module, an airflow between the first channels and the second channels is accelerated for improving heat-dissipating efficiency due to a pressure difference caused by temperature difference between the first and second base elements.
