Abstract

The combination that includes an LED (14) a light transmitting pyramid (11) mounted with respect to the LED to transmit light therefrom, the pyramid having at least three sides (11b-11d), the sides defining planes extending upwardly toward an apex (11e) that is spaced in a longitudinal direction from the LED, the planes angled in excess of 45 degrees relative to a lateral plane normal to longitudinal direction such that essentially all LED light incident on the three sides from within the pyramid is extracted from the sides.
