Abstract

The invention discloses a lamp focal length adjusting mechanism. A lamp light source is connected with a lamp radiator housing; an adjusting assembly is connected with the lamp radiator housing; the lamp light source is fixedly mounted on the lamp radiator housing through a light source bracket and fixing screws; the adjusting assembly comprises a rotating ring, a focusing lens, a lens fixing ringand a silica gel adjusting ring, wherein the focusing lens is mounted in the lens fixing ring in a snap joint manner; a protruding strip on each of two sides of the lens fixing ring corresponds to agroove in the corresponding side of the lamp radiator housing, and is mounted in the lamp radiator housing; the rotating ring is clamped on the lamp radiator housing, and positioning protruding pointsin the rotating ring correspond to oblique grooves of the lens fixing ring; and the smooth surface of the silica gel adjusting ring is connected to a groove in the outer wall of the rotating ring ina sleeving manner. Through the adoption of the lamp focal length adjusting mechanism disclosed by the invention, the problems that in the prior art, in the process of lamp focal length adjustment, themachining accuracy requirement is high, the processing cost is high, the adjusting process is not smooth and the mechanism is unstable after being used for a long term, are solved; and the lamp focallength adjusting mechanism is simple and compact in structural dimension, low in cost, and stable in effect.

Description

Technical field [0001] The present invention relates to the field of lighting technology, in particular to a focal length adjustment mechanism of a lamp, in particular to an adjustment mechanism that drives another (or a group of) optical components to move in the vertical direction by manually rotating a certain structure of the lamp horizontally. Background technique [0002] In different lighting places, the light distribution of lamps presents different requirements, especially local lighting and accent lighting require lamps to control their projection lighting range, including the angle control of the lamp projection. [0003] In the past, most lamps used a fixed light distribution angle for lighting, and there was a disadvantage that the lighting range was not adjustable; there were also a few lamps that used adjustable light distribution angles for lighting, but after too many adjustments, it was caused by wear or loosening of screws and increased temperature of the lamps. ...
