Signaling and lighting device e.g. signal lamp, for motor vehicle, has bonnet type flow collector with input and front output faces collecting maximum light flow from LED and offers desired spreading of beam by reflector

摘要

The device has an optical part (Q) formed by a bonnet (Ga) type flow collector (G), which surrounds an axis of an LED. The bonnet is made in transparent material of refractive index more than the refractive index of air. The bonnet has an shaft shaped input face (2) that covers the LED with a peripheral wall (2a), and a front output face (4) forming a refracting surface. The faces collect maximum light flow from the LED and offers desired spreading of a beam by a reflector. The collector distributes light that is not preferably symmetrical to revolution with respect to the axis.
