Why do all the big buildings have a red light on top of it?

-

Aircraft warning lights are high-intensity lighting devices attached to tall structures as collision avoidance measures. Such devices make structures more visible to aircraft, and are usually used at night, although they may be used during the day. These lights need to be of sufficient brightness to be visible for miles around the structure.

They have red light to avoid collision from aeroplane and helicopter, by putting red light pilot gets notification that there is some object. This is called aviation light or Aircraft warning lights. Not even in buildings but any high rise structure who's height is more than 45 meter (not very much sure about height) must have aviation lighting.

As specified by Annex 14 of ICAO regulations, Low Intensity Obstruction Lights should be used to warn the presence of obstacles up to 45m height, such as telecommunication towers, wind turbines, chimneys, cranes, buildings and other structures.

Low Intensity Obstruction Lights are the simplest devices according to ICAO standards and they have the following characteristics and uses:

  • Type A (intensity >10cd, red steady burning) can be used alone;
  • Type B (intensity >32cd, red steady burning), can be used either alone or in combination with medium intensity obstacle lights Type B, Type AB or with high intensity obstacle lights Type AB;
  • Type E (intensity >32cd, red flashing), can be used either alone or in combination with medium intensity obstacle lights, Type B. Flashing rate will be set at the same rate of other flashing beacons installed on the structure.
(Options: Dual Type(1 duty & 1 stand-by), Solar Powered)
               


We CDT supply the Low Intensity Obstruction Light, it has an advanced lighting optic that uses multiple high intensity LEDs for efficient operation. The obstruction light offers an ultra-bright light that is energy efficient and cost effective lighting solution.
The obstruction light is available in universal AC, DC and solar configurations with automatic day night operations and an alarm for remote monitoring making it the ideal product for remote locations or areas with limited access.

  • Cost effective, energy efficient obstruction lighting solution
  • Available in universal AC/DC or Solar Configurations
  • Alarm relay for remote monitoring
  • Automatic day/night operation
  • LED technology reduces maintenance time and costs
This low intensity obstruction are widely used for:
  • Tall Buildings
  • Telecommunication
  • TowersWater
  • TowersChimneysPower
  • LinesCooling
  • TowersCranes
  • Used for marking the top of obstacles up to 45 metres or higher when used in-conjunction with other obstruction lighting

Night Marking Red Obstruction Light System for Transmission Tower

-
图片
An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors (commonly multiples of three) suspended by towers or poles. Red obstruction lights are used to increase conspicuity during nighttime. The red obstruction light system is composed of flashing omnidirectional lights (L-864) and/or steady-burning or flashing (L-810) lights. When one or more levels are comprised of flashing lights, the lights should flash simultaneously 1. Single Obstruction Light. A single red obstruction light (L-810) may be used when more than one obstruction light is required either vertically or horizontally, or when maintenance is needed, and can be installed within a reasonable time. Top Level. A single steady-burning light (L-810) may be used to identify low structures, such as airport instrument landing system buildings, as well as long horizontal structures, such as perimeter fenc...
