Abstract

The invention relates to a zoom lighting device, which comprises a cover body, a light source, a first convex lens and a driving assembly, and the cover body is provided with a containing groove used for installing components; the light source is arranged in the containing groove; the first convex lens is slidably arranged in the containing groove and located on the side, close to a groove opening of the containing groove, of the light source; and the driving assembly is arranged on the cover body and used for enabling the first convex lens to move in the direction close to or away from the light source. According to the invention, the purpose of switching the high beam and the low beam is achieved, and meanwhile, the light of the light source is fully utilized.

Description

technical field [0001] The present application relates to the field of lighting technology, in particular to a zoom lighting device. Background technique [0002] A rail car is a means of transportation that can run on the track. At night, it is necessary to turn on the lights of the rail car to provide a view, and at the same time provide a certain reminder to the outside world to increase the safety of the vehicle during driving. And in actual use, rail car lights also need to have the function of switching between high beam and low beam to cope with different external environments. [0003] In the related art, the rail car light includes a cover body, a light source, a convex lens and a sunshield. The cover body is provided with a housing groove, and the material of the housing body can make the light emitted by the light source inside the housing tank only come from the housing tank. The light source is set in the accommodation groove, the convex lens is fixedly arrange...
