A light fixture may include LEDs that each emits light into a particular zone on a lens, where each zone has its own focal properties. Each LED may be grouped into one (or more) subset(s) that corresponds to the zone(s) struck by its emitted light. The LEDs may be selectively electrically controllable, so that the amount of light transmitted through each zone may be controllable by the electrical control system of the fixture. Because light transmitted through different zones emerges from the fixture having different widths, the electrical control system can directly control the amount of light emerging at each width. By mixing relatively narrow light with relatively wide light in the proper proportions, the electrical control system of the fixture may produce light having any desired angular profile between “narrow” and “wide”. One may think of the fixture having a controller that features both a dimmer, which can control the optical power or brightness of the fixture 1, and a “width” controller, which can dial in values between “narrow” and “wide” light. By varying the relative contributions of the different beam widths, the angular profile of the total output may be varied, and may advantageously be varied electronically, without any moving parts.
