Problems solved by technology
[0002] At present, projection lamps generally include a light source installed in the lamp tube, a condenser lens assembly and a zoom lens assembly sequentially installed on the front side of the light source. The zoom lens assembly generally includes two lenses, and the position of the condenser lens assembly is generally different during use. It needs to be adjusted, and the zoom lens assembly needs to change the relative position between the two lenses and the position of the two lenses relative to the light source frequently according to the different use environments. The existing zoom lens assembly is installed in the lamp tube, and when adjusting the zoom lens assembly The position is very unintuitive, and it is very inconvenient for ordinary people to adjust

Embodiment Construction
[0016] Combine below Figure 1 to Figure 3 The present invention is described in detail:
[0017] The multifunctional LED projection lamp of the present invention includes a lamp tube 1, a light source device 2 is arranged inside the lamp tube 1, and a zoom lens assembly 3 is correspondingly provided on the front side of the light source device 2, and the zoom lens assembly 3 includes two lenses arranged at intervals 32. The zoom lens assembly 3 is exposed on the outside of the lamp tube, and the user can intuitively see the position of the zoom lens assembly, so that the relative position between the two lenses and the position of the two lenses relative to the light source can be adjusted conveniently.
[0018] In this embodiment, the front end of the lamp tube is provided with two guide columns 33 parallel to each other, and each lens 32 is slidably installed between the two guide columns through a sliding seat 35, and each sliding seat is connected to the guide column. Po...
