HZ-70A / B-type double-headed aviation lights flash obstacles are two sets of micro-computer chips from circuit to low-power, ultra-high-brightness long-life LED light-emitting diodes as a light source, through the control of low power integrated circuit (electronic devices for the military class components), to recharge during the day, night shining, is the latest R & D aids to navigation of a product, a set of main lights work, another set of backup lights, vice, such as the work of the main lamp fails, the lights automatically switch to the vice continue to work to achieve the life of the lamp device, but also can be used as both primary and secondary lights flash alternately. Are designed to inconvenience the maintenance of the high-rise buildings, chimneys, communications tower, lightning rod, as well as a special place designed aids to navigation. Working Voltage: AC220V or DC12V/DC48V Power consumption: 10W Flash frequency: 20-60 times / min Light sensitivity control: 50-300LX Effective light intensity: 1600cd Light Source Life: 100,000 hours Working environment: -40 °C +70 °C Protection Level: IP65 Dimensions: 230mm × 180mm × 380mm Chassis installation: 150mm pitch circle diameter of 180mm are 4 hole cloth x10mm The use of: H ≤ 90 meter (H for high building objects) Light weight browser: 4kg
