Abstract

A lighting assembly and method generate a three-dimensional lighting effect with parallax, depth and brightness variability or twinkling among different viewing angles using an LED substrate and different optic component layers including one or more obscuration patterns and a reflection chamber for unobscured light from LEDs components not obscured by the one or more obscuration patterns. The LED substrate can employ mini or micro scale package LEDs or their unpackaged LED dies for slim profile lighting assembly. The LED substrate and different optic component layers can be curved, employ direct illumination and occultation imaging.
