Abstract
The present invention relates to LED lamps suitable for forming automotive lighting systems, made of high power lambertian LEDs and a TIR collimator lens. In the present invention, a novel TIR collimator lens is developed to collect the light emitted from the LED source and through a pillow lens array; redistribution occurs to form a light pattern meeting ECE requirements.
