The Anti Collision Lamp is the part of Anti collision system and is powered by strobe light power unit. Both the upper and lower Anti-collision light units in Hawk Aircraft are connected to the strobe light power unit through two cable assemblies. The xenon tubes are ignited by the ignition impulse generators in the strobe light power unit through high voltage oscillations. The flash energy generated by the strobe light power unit to drive xenon tube is about 30 to 40 Joules at a flash rate of 90 ± 10 flashes/min. The Anti collision lamp is categorized as safety critical item.
