Multi-functional table lamp

Abstract

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.

Description

technical field [0001] The invention relates to a desk lamp, in particular to a multifunctional desk lamp. Background technique [0002] At present, desk lamp occupies a pivotal position in people's life and study, and is widely used in places such as family or office. Desk lamps are mainly placed on desks or dining tables for lighting purposes, and are movable lamps. The light irradiation range of the desk lamp is relatively small and concentrated, so it will not affect the light of the whole room, and the effect is limited around the desk lamp, which is convenient for reading and learning, and saves energy. For easy portability, folding desk lamps are widely used. [0003] The desk lamp uses light-emitting diodes as the light source. When the light-emitting diodes emit light for a long time, the light-emitting diodes will generate heat due to the resistance. If the heat is too high, the service life of the desk lamp will be shortened. In particular, when the foldable de...

Problems solved by technology

In particular, when the folding desk lamp needs to be folded and put away after use, the heat is more difficult to dissipate, and the service life of the bulb of the folding desk lamp will be greatly reduced
