Provided is a splicing-type lamp. The splicing-type lamp comprises a mounting base station, splicing assemblies and LED light-emitting assemblies. The mounting base station is provided with a plurality of mounting grooves, and the inner side walls of all the mounting grooves are provided with first magnetic attraction parts. The splicing assemblies comprise a plurality of splicing pieces. Each splicing piece comprises an embedded heat conduction head, a second magnetic attraction part and a mounting base, wherein the second magnetic attraction part is arranged on the embedded heat conduction head; the embedded heat conduction head is embedded into the mounting groove; and the second magnetic attraction part and the corresponding first magnetic attraction part are attracted in magnetism. The LED light-emitting assemblies comprise a plurality of LED lamp beads. The LED lamp beads are arranged on all the mounting bases in a one-to-one correspondence mode. When the number and brightness of the LED lamp beads need to be adjusted by users, the corresponding number of spliced combinations of the splicing pieces and the LED lamp beads only need to be inserted into all the mounting grooves in a one-to-one correspondence mode. The total number of the LED lamp beads can be adjusted according to the corresponding number of the splicing pieces on the mounting base station, and the effect of brightness adjustment can be achieved easily.
