Claim 0:
1. An LED matrix lighting device for illuminating a lighting pattern with even intensity, the LED matrix lighting device comprising a plurality of LEDs, a collimating lens in front of each LED for collimating light of the LED, and a light refracting element in front of collimating lenses arranged to refract light of at least a first part of the LEDs with a different refraction angle than at least a second part of the LEDs, and wherein current provided for at least one LED is adjustable based on detected intensity deviations in a captured image, and which a FWHM viewing angle of the collimated light of LEDs is substantially as large as the difference between the refraction angles.
