Abstract
A flashlight has a lens moveable relative to an LED. The beam of light provided by the LED can be focused and provides a uniform light pattern across the range of focus. The lens is supported on a front housing section and the LED is supported on a back housing section threaded onto the front housing section. Twisting the front housing section closes a switch providing power to the LED, to turn the flashlight on. A circuit module within the flashlight provides various operating modes including an automatic shut-off timer, to preserve battery life, a dimmer controlled by turning an end cap, a blinking function, and/or a current control function to provide maximum brightness regardless of battery condition.
