LED ceiling lamp with built-in driving power supply

Abstract

The invention discloses an LED ceiling lamp with a built-in driving power supply. The LED ceiling lamp structurally comprises a boom, a connecting seat, a heat dissipation device and a lampshade; the boom and the connecting seat are fixedly connected, and the connecting seat is located between the boom and the lampshade; the connecting seat is mounted at the top of the lampshade, and the heat dissipation device is mounted in an inner cavity of the connecting seat; and the end, away from the connecting seat, of the boom is fixedly connected with a ceiling, and the inner cavity of the connecting seat communicates with the lampshade. The LED ceiling lamp has the beneficial effects that heat generated during working of the driving power supply is utilized to promote a hollow air bag thin layer to move in the direction where a heat dissipation port is located so as to achieve the purpose of pushing two telescopic door plates to oppositely move, thus the heat is dissipated outwards through the heat dissipation port, an air bag is filled with the heat, thus the air bag blocks a hollowed-out frame on a circular plate, and the problem that the heat generated during working of the driving power supply and heat generated during working of lamp beads in the lampshade are converged is solved.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to an LED pendant lamp with a built-in drive power supply. Background technique [0002] The service life of the luminaire is related to the heat generated by the luminaire when it works for a long time, and the heat dissipation speed. In particular, the heat dissipation of the LED luminaire with a built-in drive power has attracted much attention. The current LED chandelier with a built-in drive power has the following defects: [0003] The traditional built-in drive power LED pendant lamp achieves the purpose of dissipating heat by installing the LED lamp beads in the lampshade, and installs the drive power on the lamp holder. Since the outer layer is a metal layer and is rotated in a threaded structure, the lamp holder The heat generated by the internal drive power supply cannot be dissipated and is transmitted to the LED lamp beads in the lampshade, causing heat to gather again.
