Improved lighting system lamp units used on airport taxi-ways, takeoff and landing runways

摘要

The lamp unit (1) has a transparent part (16) in which a lamp, designed to be connected to an electrical source (7), is located. The lamp produces a characteristic beam. The lamp includes a supply module (7). designed to be fed from a current source, and an electrical circuit, designed to be fed from the supply module (7), which includes a number of electro-luminescent diodes (21). These LED's are positioned according to a chosen configuration, inside the transparent part of the lamp unit (1) and are designed to a sub beam, wavelength between 450 to 480 nanometers, preferably 470 to 475 nanometers,, of chosen characteristics which is part of the transmitted beam..
