Working power of aviation obstruction light?

The working power of aviation obstruction lights is different. As the installation height increases, obstruction lights can be divided into low-intensity aviation obstruction lights, medium-intensity aviation obstruction lights and high-intensity aviation obstruction lights. The working power is different.

The following mainly introduces the operating power of the Huaguangfa aviation obstruction light brand:

1. The main working power of high-intensity aviation obstruction lights is 150W;

2. The main working power of medium intensity aviation obstruction lights is 25W;

3. The main working power of low-intensity aviation obstruction lights is 5W.

Aviation obstruction lights luminous color classification

The rules of aviation obstruction lights in CAAC (Civil Administration of China)that aviation obstruction lights are still installed with height classification, and they are identified by different flashing colors.

Low intensity type A aviation obstruction lights, red constant light fixtures, installed on obstacles below 45 meters or on the ground floor of the airport clear area.

Medium intensity type A aviation obstruction light, white flashing device, installed on obstacles from 105 meters above to 150 meters below.

Medium-intensity type B aviation obstruction lights, red flashing lights, installed on obstacles above 45 meters to 105 meters below.

High intensity type A aviation obstruction light, white flashing device, installed on an obstacle of 150 meters (or above).

2. How to install aviation lights?

How to install aviation lights in high-rise buildings_How to install obstruction lights in high-rise buildings?

High-rise buildings refer to buildings whose height exceeds the surrounding ground by 150 meters or more. They are called high-rise buildings (or super-high buildings). These buildings need to be installed with aviation obstruction lights in accordance with the regulations of the Civil Aviation Administration of China on aviation obstruction lights. .

The installed aviation obstruction lights must be installed and set up in accordance with the 2015 new aviation obstruction light specification "MH/T 6012-2015" of the Civil Aviation Administration of China.

Assuming that the building is 150 meters high, according to the 2015 new aviation obstruction light code, high-intensity aviation obstruction lights and medium-intensity aviation obstruction lights are required to be designed together to serve as an aviation warning.

1. High intensity aviation obstruction lights need to be installed on the roof of the building. The number of high intensity obstruction lights needs to be set with reference to the floor plan of the building, mainly to indicate the vertex position of the floor;

2. Set up medium intensity aviation obstruction lights at an interval of 45 meters, that is, 105 meters. Medium intensity type A aviation obstruction lights or medium-intensity B-type aviation obstruction lights can be set;

3. Set up medium intensity type B aviation obstruction lights at an equal interval of 45 meters in turn, that is, at a height of 60 meters;

Considering the situation of light pollution, three-layer aviation obstruction lights can be installed. While playing the role of aviation warning and guiding, it will not affect the normal life of the residents of the building group.

3. Installation

3.1 Schematic Diagram

3.2 Instruction

a) Please read carefully the product specification before using the driver to make sure the operation environment can meet the requirement as per the specification.

b) While connecting the tube to the power, please make sure the switch is “off”.

c) Do not disassemble the lamp by yourself.

4. Maintenance

4.1 Check light condition every 2~3 month, when malfunction is founded, report to supplier immediately;

4.2 Keep the light away from hazardous environment, install it in the designative location；

5. Standard

All kinds of aviation obstruction lights should be ICAO(International Civil Aviation Organization) or FAA(Federal Aviation Administration) compliant. ICAO FAA both have a standard regarding all kinds of aviation obstruction lights, all lights should be designed and installed according to ICAO or FAA standard. In China, the standard is called “CAAC”(Civil Aviation Administration of China). All kinds of aviation obstruction lights should be compliant with CAAC when they are sold.
