发明名称 CASSEGRAIN OPTICAL CONFIGURATION TO EXPAND HIGH INTENSITY LED FLASHLIGHT TO LARGER DIAMETER LOWER INTENSITY BEAM
摘要 A flashlight in accordance with an embodiment of the present application includes an LED light source, a lens positioned opposite the LED light source, a convex mirror positioned substantially in a center of the inner surface of the lens, wherein light from the LED light source is reflected off the convex mirror back toward the LED light source and a concave mirror positioned opposite the convex mirror to reflect the light from the convex mirror as a wide diameter beam of light out of the flashlight through the lens.
