ABSTRACT:
An optical system for an LED array includes a trough reflector in combination with an elongated lens. The reflector and lens include distinct regions dedicated to particular zones of light emanating from the LED array. The reflector includes lower, upper and end portions, each configured to redirect a particular zone of wide angle light from the LED array into a pre-determined warning light pattern. The lens includes central, side and end regions, each configured to redirect a particular zone of narrow angle light from the LED array into the pre-determined warning light pattern. The shape of the trough reflector and lens, as well as the relationship between the lens and reflector, are selected to provide an optical system with expanded illuminated surface area and a low profile.
