Technical Field

[0001] The invention relates to the technical field of spotlights, and in particular to an integrated lamp with adjustable photoelectric parameters. Background Art

[0002] At present, LED projection lamps are mainly used to create atmosphere and lighting, and are more commonly used in outdoor environments. In order to improve the lighting effect of the projection lamp, a lens assembly for focusing is usually configured. For example, the variable focus LED lamp disclosed in Chinese patent CN202109280U includes a lamp head, a lamp tube with an LED light source, and a lamp holder. The lamp head is fixed to the front end of the lamp tube, and the lamp tube is fixed to the lamp holder. The outer surface of the lamp tube is provided with a spiral groove, and an external magnet is provided in the spiral groove. The external magnet protrudes out of the spiral groove. The outer surface of the lamp tube is covered with a focusing tube, and the inner surface of the focusing tube is provided with an axial groove that matches the external magnet. The interior of the lamp tube is covered with a lens column, and the lens column is located in front of the LED light source. A convex lens is fixed inside the lens column, and an inner magnet that attracts the external magnet is inlaid on the wall of the lens column.
