Beschreibung
Zusammenfassung:	The invention belongs to the technical field of visual inspection, and particularly discloses a multi-color point light source, which comprises a first light source, a second light source, a third light source, a light splitting and gathering module and a shell. The first light source, the second light source and the third light source are used for emitting light of different colors. The first light source and the second light source are symmetrically arranged; the third light source is arranged between the first light source and the second light source; the light splitting and gathering module is used for gathering light rays emitted by the first light source, the second light source and the third light source to gather light spots in the same area; free switching of multiple waveband colors can be realized by only one light source by utilizing the light gathering effect of a lens, the reflection and transmission characteristics of a light splitting film and the three-primary-color combination principle of l
