Abstract

The invention provides a lamp, which comprises a first lamp body and a second lamp body, wherein the second lamp body is coaxially arranged with the first lamp body and can rotate around a shaft, an inner cavity communicated with the first lamp body and the second lamp body is formed in the first lamp body, a light source component is positioned in the inner cavity and fixed with the first lamp body, the light source component comprises light emitting components with more than two colors, a focusing component is rotatable and fixed with the second lamp body, and the second lamp body drives the focusing component to rotate and move along the shaft relative to the light source component when rotating relative to the first lamp body. The focusing piece moves in the common axial direction of the two lamp bodies, so that the distance between the second optical piece and the first optical piece is adjusted, and the focusing process is realized. And moreover, by adopting a light source secondary light mixing mode, bad light spots in the primary light mixing process are reduced, the light emitting effect is improved, and meanwhile, the angle adjustment of the illumination direction can be realized by matching with the focusing process.
