From the ground 90 meters above the building and facilities

From the ground 90 meters above the building and facilities: use led traffic barricade lights intensity obstacle lights red flash, flash frequency should be in 20-60 times per minute, the effective intensity of flash of not less than 1600cd; or the use of high intensity disturbance red lights, the flash effect more obvious. From the ground 150 meters above the building and facilities, the use of high intensity obstacle lights and must be white flash, flash frequency should be in 20-70 times per minute, the effective intensity varies with the background brightness. Traffic barricade light, light-emitting diode, is a solid semiconductor light emitting device,it is used as beacon warning light emitting materials by solid semiconductor chip, when the two ends together with the forward voltage, carriers in semiconductor compound induced photon emission and produce light.
