Beacon lights (navigation mark light), a class of traffic lights to ensure that ships in the night safe navigation installed in some beacon. It issued the provisions of a light color and flash frequency during the night, to achieve the required illumination angle and visibility distance. Beacon lights are fixed beacons, light buoys, lightship and the lighthouse of four kinds. Fixed beacons, light buoys and light vessels for navigation and warning beacons. The lighthouse at sea day and night issued identifiable signal for the ship to determine the site and provide hazard warning to ships.
LED navigation light (t5 high bay fluorescent) is generally promoted in recent years a new beacon, is increasingly being recognized the great importance of the maritime sector. Rational selection and proper use of LED Lights navigation light is very important. In addition to the LED light source used in the plane applications of beacon lights, bridges and culverts standard and rotating lights, the more LED beacon light (t5 high bay fluorescent) ring to the application. At present, the world beacon manufacturers defined the parameters of the LED beacon light is still used in the exit surface of the light intensity and the vertical divergence angle of the two indicators.
LED the monomers device as a light source applications, usually with a certain angle of perspective, to ensure that the light intensity within the established range of perspective, perspective other than the intensity attenuation of the light intensity / viewing angle characteristics curve, LED monomer The device is a directional light source, rather than the full 4 solid angle space to the point light source, LED device manufacturing ring to beacon lights and LED Tubes, the lens is different from the ordinary point light source lens.
For the LED ring to beacon lights, LED (t5 high bay fluorescent) is a special light source. LED monomer devices with a small optical lens. The lens to the point light source on the semiconductor chip clustered into a certain solid angle of the beam, in nominal solid angle, the nominal output light intensity. Comparison of LED lens ring to beacon lights and traditional single-lens cone Philippine Cornell beacon of light, the difference between the former focus is in the center of the lens, while the latter is in the luminous circle.
