Light fixture for generating high-visibility light beams at long distances

A light fixture includes a source assembly comprising at least one solid state light source and configured to generate a light beam in an emission direction; and at least one outlet optical assembly arranged so as to intercept the light beam emitted by the source assembly. The outlet optical assembl...

Beschreibung
Zusammenfassung:	A light fixture includes a source assembly comprising at least one solid state light source and configured to generate a light beam in an emission direction; and at least one outlet optical assembly arranged so as to intercept the light beam emitted by the source assembly. The outlet optical assembly comprises at least one outlet lens, which is arranged so as to be the last lens that intercepts the light beam, at least partially. The outlet lens is sized so that the optical efficiency of the light fixture is at least equal to 90%; wherein optical efficiency is the ratio between the etendue of the beam being emitted from the outlet lens and the etendue of the source assembly in accordance with the following relation:OPTICAL EFFICIENCY=EtendueOUT/EtendueSOURCE·100.
