A double-lens zooming flashlight, comprising a lamp cap (1), a barrel body (2), a light-emitting element (8), and two flat convex lenses (5, 4), and the double-lens zooming flashlight is characterized in that: the lamp cap (1) is sleeved on the front portion of the barrel body (2), and is in a rotating and telescopic connection relative to the barrel body (2); the two flat convex lenses (5, 4) are both disposed perpendicular to the front optical axis of the light-emitting element (2); the first flat convex lens (5) is fixedly disposed in the front end of the barrel body (2) and has a fixed distance from the light-emitting element (8); and the second flat convex lens (4) is disposed in the front of the lamp cap (1) and moves back and forth relative to the light-emitting element (8) with the rotation and telescopic movement of the lamp cap (1) and the barrel body (2). The flashlight zooms via the combination of the two lenses (5, 4), and changes the distance therebetween via the rotation of the barrel body (2) or the lamp cap (1), thus achieving the purpose of zooming and improving the illumination range and brightness. In addition, the flashlight has a simple structure and reasonable design, and eliminates the need for additional zooming cover or lens, thus simplifying manufacture and saving costs. Furthermore, the barrel body (2) being telescopic facilitates carrying and storage. |
