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.

A lens for a flashlight or other lighting unit provides for focusing light from a source, such as an LED, to provide a light beam adjustable between a spot beam and a wide beam. The lens includes a lens body with a front face, a rear LED-receiving well, and a side surface extending between the front face and the rear well. The front face includes a central surface surrounded by an annular concave surface. The rear well includes a space for the LED to be adjusted in position. The rear well space is defined by a concavely-curved sidewall and a concavely-curved base. The concave curvature of the sidewall and base may be Bezier curves.
