Definition and function
Beacons are conscious devices designed to attract attention to specific locations.
Beacons can also be combined with metaphors or other indicators to provide important information such as the state of the airport, the color and rotation pattern of its airport beacons, or the weather to be installed, such as weather beacons installed at the top of tall buildings or similar venues. When used in this manner, the beacon can be considered a form of optical telegram.
Beacon in the car
The vehicle signal light is a rotating or flashing light that is attached to the top of the vehicle to draw the attention of surrounding vehicles and pedestrians. Emergency vehicles such as fire trucks, ambulances, police cars, trailers, construction vehicles and snow removal vehicles carry beacon lights.
The color of the lamp varies from jurisdiction to jurisdiction; typical colors for police, fire and medical emergency vehicles are blue and/or red; amber is dangerous (slow car, wide load, trailer, security guard, construction vehicle, etc.); green volunteer firefighters Or medical staff, purple for cruel vehicles. The beacon can be constructed using a halogen bulb similar to a vehicle headlamp, a xenon flash tube or an LED. Incandescent and xenon light sources require the vehicle's engine to continue to operate to ensure that the battery does not run out when the lamp is used for an extended period of time. The low power consumption of the LED allows the vehicle's engine to remain off while the lamp is operating the node.
