Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving lamps, and in particular to a soldering-free lamp holder structure which is convenient for replacing light sources. Background Art

[0002] Most existing lamps are energy-saving lamps or LED lamps. Regardless of whether they are energy-saving lamps or LED lamps, they generally include a lamp head, a light source and a lampshade. The lamp head is used to connect to the lamp holder to connect the power signal of the lamp holder to the light source of the lamp. The lampshade covers the lamp head to protect the light source.

[0003] For example, the Chinese patent with publication number CN117570403A discloses a lamp holder structure with a replaceable light source, which includes at least one lamp holder assembly, and a bulb assembly is arranged inside the lamp holder assembly. The lamp holder assembly includes a lamp holder shell and a lamp holder plastic shell arranged inside the lamp holder shell, and a low-voltage quick-connect terminal plastic shell is arranged inside the lamp holder plastic shell. At least two high-voltage wire cores and at least two low-voltage wire cores are passed through the interior of the lamp holder shell, and one end of the low-voltage wire core is fixedly arranged inside the low-voltage quick-connect terminal plastic shell. When the light source needs to be replaced, it is necessary to unscrew the bulb assembly, and then pull out the light guide column and the lamp board, so that the conductive terminal is separated from the low-voltage quick-connect terminal plastic shell. However, after long-term use, the conductive terminal and the lamp board are prone to aging.
