FLASHLIGHT WITH LIGHT FOCUSING SYSTEM

摘要

A twist push light focusing system for a flashlight includes a focus member movable in a longitudinal direction of the flashlight :a light source; a focus leas; and a rotational-to-longitudinal movement translation mechanism operably coupled to the focus member and at least one of the light source and the focus lens to translate longitudinal movement of the focus member into rotational movement In the rotational-to-longitudinal movement translation mechanism and relative longitudinal movement between the light source and the locus lens to achieve focus.
