Abstract
A luminaire that can resist the shock associated with a ballistics event and continue to operate. The luminaire has a base formed from high ductility aluminum. An illumination source, such as a light emitting diode array, is secured to a support of the base. A lens having a gasket is positioned over the illumination source and secured thereto with a clamp. A ballistic shield having a dual gasket is coupled to the clamp by a bezel positioned over the ballistic shield and secured to the clamp. The gaskets extending around the peripheral edges of the lens and the shield cooperate with the highly ductile aluminum base to reduce the transmission of any shock associated with a ballistic event to the illumination source and associated electronics.
