A LED-based lighting assembly uses minimized distance between an LED source and a diffuser to reduce form factor size, and convex optics, elliptical diffusion and lateral recycling to produce from mini- or micro-chip LEDs a uniform geometrical shape for lit-pixel display of information at high definition. A less than one-to-one (1:1) ratio of LED chip distance and vertical distance between chip and diffuser is achieved with desired uniformity of lit-pixel displays. Reduced distance between diffuser and LEDs and an improved optic provide for more dense yet compact configuration of LEDs in lighting components of automobile grilles and emblems and other lit branding or safety devices in commercial and residential applications.
