Abstract
The present disclosure relates to a thin-profile lens for shaping a beam of light from a light source, such as a light emitting diode (LED), for example in a flashlight or other lighting unit. In various embodiments, the lens may be combined with an adjustment mechanism for varying the focus of the beam of light, and may be housed in a structure supporting the lens, light source, and adjustment mechanism. In various embodiments, the structure also may include a power source, controls, interconnections, and electronics. In various embodiments, the thin profile of the lens may allow the lens to be used in any of a number of applications, ranging from narrow diameter flashlights to large diameter light sources.
