The all-round automatic mobile light tower is a point light source that can irradiate evenly in all directions. automatic mobile light towers irradiating range can be adjusted arbitrarily, and it appears as a regular octahedron icon in the scene. Omni-directional automatic mobile light towers produce highly diffuse, non-directional light rather than a well-defined beam, resulting in soft, transparent shadows that fade faster when used for object lighting than when illuminated with spotlights Much slower, what are the requirements for the use of omni-directional automatic flood work lights at airports?
The high pole light on the apron is the main facility for the floodlighting of the apron, and the Power Energy Security Department is responsible for the daily management, inspection and maintenance of the high pole light and power supply cables and other facilities.
In order to ensure the safe and effective operation of aircraft in the apron work area at night and in low visibility conditions, and to make the apron all-round aautomatic light tower safe, applicable, advanced in technology and economical and reasonable, this standard is formulated.
The apron floodlights must provide sufficient illumination for the apron work area, and must enable the graphics and colors of aircraft markings, ground markings and obstacle markings to be correctly identified.
The layout and orientation of all-round automatic floodlights on the apron should enable each machine position to receive light from more than two directions, so as to minimize shadows, and attention should be paid to the following aspects.
1. The apron floodlight lighting should not produce glare that hinders aircraft pilots, tower controllers, and ground staff.
2. The intact rate of the apron floodlights should not be lower than 80%, and the whole group of lights is not allowed to be off.
3. The area on the apron for aircraft parking and ground operations and its adjacent areas.
4. Aircraft stand, a specific site on the apron for parking aircraft.
5. Airport clearance, the space above the obstacle surface stipulated to ensure the safety of aircraft takeoff and landing, is used to limit the height of obstacles in the airport and its surrounding areas.
6. Illuminance, the illuminance at a point on the surface is the quotient of the luminous flux dФ incident on the surface element containing the point divided by the area dA of the surface element. The symbol is E, the unit is lux (lx), 1lx=lm/㎡.
7. Flood lighting, usually using floodlights to illuminate a large area or scene, so that the illuminance of the illuminated surface is significantly higher than the illuminance of its surrounding environment.
8. Illuminance uniformity is the ratio of the minimum illuminance to the average illuminance on the specified surface.
9. Illuminance gradient, the illuminance gradient represents the rate of change of illuminance between adjacent grid points.
10. Glare is a visual phenomenon that causes discomfort or reduces the ability to observe details or targets due to inappropriate brightness or brightness distribution in the field of view, or extreme contrast.
