| 摘要 |
A field emission lamp is disclosed, which comprises: a substrate, a plurality of first field emission units, a plurality of second field emission units, and a driving control unit. The plurality of first field emission units and the plurality of second field emission units are located on the substrate. Besides, the first phosphor layer of the plurality of first field emission units has a first color temperature. The second phosphor layer of the plurality of second field emission units has a second color temperature, wherein the first color temperature is higher than the second color temperature. Moreover, the driving control unit drives and controls the plurality of first field emission units and the plurality of second field emission units based on a predetermined driving mode, for modulating the light emission mode of the field emission lamp and the color temperature of the mixed light emitted from the field emission lamp.
