Abstract: Disclosed are flashlights that optimize the light output and beam focus of both a flood beam and a spot beam. The disclosed flashlights include a housing member and a lens including a first focusing element adapted to shape a light beam into a spot beam and a second focusing element adapted to shape a light beam into a flood beam. A first LED is positioned to direct light through the first focusing element, and a second LED positioned to direct light through the second focusing element. The first LED has a smaller die than the second LED, and the distance between the first LED and the first focusing element is greater than the distance between the second LED and the second focusing element.

Abstract: 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.
