Abstract

The invention provides an LED (light-emitting diode) ceiling lamp, which comprises a drive box and a circuit board. The drive box is internally provided with an accommodating cavity with an opening facing downwards, the circuit board is arranged in the accommodating cavity, a plurality of fixing columns are fixedly arranged inside the drive box, the lower ends of the fixing columns are provided with convex parts, the circuit board is provided with through holes, and the convex parts are arranged in the through holes in a penetrating way and are connected with the circuit board in a detachable way. Since the circuit board is connected with the fixing columns in the drive box in the detachable way, detachable connection of the circuit board and the drive box can be realized, the circuit board can be conveniently placed into the drive box and taken out of the drive box, replacement of the circuit board can be facilitated during a testing process, labor and material resources can be saved, the production cost can be reduced effectively, the production efficiency can be improved, and the circuit board and the drive box can be effectively prevented from being damaged during replacement of the circuit board.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED ceiling lamp. Background technique [0002] LED ceiling lamp is a new type of lamp, which uses LED as its light source.
