The invention relates to a multi-functional table lamp. The multi-functional table lamp comprises a supporting pillar, and a lampholder is hinged to the lower end of the supporting pillar; an
air cavity is formed in the supporting pillar; the lower end of the
air cavity is sealed; the upper end of the
air cavity is open; a
piston is arranged in the air cavity in a sliding manner; a push rod is connected to the upper end face of the
piston; an adapter rod is hinged to the upper end of the push rod; the adapter rod is rotatably mounted at the upper end of the supporting pillar; a
bulb mounting plate is fixedly connected to the end, away from the push rod, of the adapter rod; an annular air sac is mounted on the outer side of the push rod in a sleeving manner; the annular air sac is providedwith air inlet-exhaust hole groups; through holes are formed in the positions, corresponding to the air inlet-exhaust hole groups, of the side wall, facing the folded
bulb mounting plate, of the air cavity; the upper end of the annular air sac is fixed to a partition; the partition is fixed in the air cavity; and the lower end of the annular air sac is fixed to the
piston. According to the multi-functional table lamp, heat of a
bulb and the bulb mounting plate can be well dissipated, the service life of the bulb is prevented from being affected by high temperature, and the service life of thetable lamp is prolonged.
