Distinguishing Aviation Obstruction Light Types by Optical Identification

There are three types of aviation obstruction lights, namely, low light intensity, medium light intensity, and high light intensity. Three different types also include obstruction lights of different types of A and B, such as medium A and medium B. These two lamps are similar in shape. , then how to distinguish it. In fact, it is very simple, it can be used to identify the different types of aviation obstruction lights.

At present, the illuminance color of aviation obstruction lamps is mainly red and white. In our life, white light is used for illumination. Actually, white light is generated by blue chips plus yellow phosphor to achieve white light, and the on-voltage is 2.4 to 3.5V. The red light is composed of a red light chip, which is generally used for an indicator lamp and has a turn-on voltage of 1.6 to 3V. For different types of aviation obstruction lights, the color of the light is also very different, 105 meters can be used as a demarcation point, below 105 meters are usually red light, most of the above 105 meters is white light, the specific situation is as follows:

How to discriminate aviation obstruction lights by glowing colors

China Aviation Administration’s regulations concerning aviation obstruction lights require that aviation obstruction lights are still installed with a height classifier, which is identified by different flash colors.

Low-light intensity type A aviation obstruction light, red permanent light fixture, installed on the obstacle below 45 meters or above the ground floor of the airport clearance area.

Zhongguangqiang A-type aviation obstruction light, white flashlight, installed on obstacles from 105 meters to 150 meters.

Zhongguangqiang B aviation obstruction lights, red flashlights, installed on obstacles of 45 meters to 105 meters.

Gao Guangqiang Type A aviation obstruction light, white flashlight, mounted on an obstruction of 150 meters (or more).
