The intensity of aviation obstruction lights can be divided into high, medium and low. Among them, the high-intensity aviation obstruction light intensity is 2000 to 200,000CD, the medium-intensity aviation obstruction light intensity is 2000 to 20000CD, and the low-intensity aviation obstruction light is 10 to 32CD. Low-intensity aviation obstruction lights can also be called low-light aviation obstruction lights, which are divided into four models: A, B, C, and D.
How strong is the 10CD light intensity of low-intensity aviation obstruction lights? According to calculations, the 10CD light intensity is approximately equal to 125.6lm, and 1lm is equal to the electromagnetic energy radiated by 1.46 x 10^-3W at a frequency of 5540 THz. This is a very soft brightness, enough to ensure that the naked eye does not feel glaring at a distance of 2 meters from the light source.
Generally speaking, low-intensity aviation obstruction lights are aviation obstruction lights installed on obstacles whose height does not exceed 45 meters below the surrounding road surface. It is generally installed on buildings or obstacles that are less than 45 meters above the airport. When the height of the obstacle exceeds 45 meters above the surrounding road, it can be combined with the mid-intensity aviation obstruction light partner application to mark the wide and high visibility of the obstacle, to assist the operator of the aircraft to find the obstacle And quickly bypassed.
Low-intensity aviation obstruction lights are widely used in high-rise buildings, civil airports and air force, airport clear space buildings, heliports, communication towers, chimneys, ports, wind power plants, bridges and urban high-rises, but the most used places are counted. Airport. The reference standard is ICAO (No. 14 Annex) low-intensity obstruction light standard and FAA-L810 classification.
