LED navigation light 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 navigation light is very important. In addition to the led power 10w light source used in the plane applications of beacon lights, bridges and culverts standard and rotating lights, LED beacon light 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 1w 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, the lens is different from the ordinary point light source lens.
For the LED ring to beacon lights, LED is a special light source. LED monomer devices with a small optical lens. The lens will gather point source on the semiconductor wafer into a certain solid angle of the beam, in nominal solid angle, the nominal output light intensity. LED devices, such as the viewing angle is the solid angle of 30 °, 30 ° solid angle output nominal light intensity, and more than 30 °, light forcing a faster decay. LED Ring is the beacon of light with a certain perspective of the led power 50w devices arranged evenly on the circumference of a certain diameter, if we put this LED devices arranged in a circle known as the luminous circle, then the LED ring to the navigation light on a specially designed ring Philippine Cornell lens is a luminous circle lens focus; special lens focal length to the distance between the luminous circle with the lens surfaces. 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.
1, the led 10w beacon lamps light distribution characteristics of a good standard
Standards with light indicator using the standard of general characteristics of light distribution curve expressed in multiple concentric weeks, you can visually see that it's peak - valley, and through the precise positioning coordinates to determine the percentage of the peak - valley. Under normal circumstances, the peaks and valleys the closer, the better the performance of their standard light distribution. Standards with excellent optical characteristics of the beacon, its peak - valley are generally less than 10%.
2, LED beacon lights and advanced drive circuit
Modern LED beacon lights must have a high conversion efficiency of the drive circuit (generally use switching power supply), the use of software to achieve high-precision flash cycle; with the wisdom of self-detection circuit and with a standard computer port control circuit, which can be easily access to all kinds of Telemetry System, or AIS system.
LED beacon lamps have a higher optical / electrical conversion efficiency
High Power LED 50W beacon lights, in the same power, the same divergence angle conditions, the higher the light intensity values, the optical / electrical conversion efficiency of the higher use, the more power saving. Improve the optical / electrical conversion efficiency of a lot of ways, but mainly is to design the reasonable control and power driver circuits.
4, LED beacon lamps have a good machine protection performance
LED beacon lights obviates the traditional bulb replacement instrument of mechanical moving parts, can be made watertight structure of the whole lamp. All-watertight structure, even if the entire beacon lights immersed in water, in addition to normal work but also through non-contact way to achieve remote monitoring.
LED beacon lights can be widely used in coastal and inland aids to navigation, can also be used for aerial obstacle lights, oil platform explosion-proof lamps.
