The present disclosure relates to a focusing optic 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 focusing optic includes a central focusing element configured to direct a light beam from an LED in a desired direction; a side wall extending from the central focusing element, wherein the side wall is configured to form a rear void for receiving the LED; and an annular ring portion extending from the side wall and surrounding the central focusing element, wherein the annular ring portion is adapted to reflect light in a desired direction. In some embodiments, the side wall and annular ring portion together define a thickness dimension that varies less than 20% over the lens body. |
