Abstract
A lighting device including a plurality of light-emitting semiconductor devices. The light-emitting semiconductor devices are separated into at least two subgroups. The lighting device further includes a plurality of optics separated into at least two subgroups, which are arranged relative to the plurality of light-emitting semiconductor devices such that each one of the plurality of light-emitting semiconductor devices of a first subgroup is located at a focal point of a respective optic of a first subgroup of the plurality of optics, and such that each one of the plurality of light-emitting semiconductor devices of a second subgroup is located at a focal point of a respective optic of a second subgroup of the plurality of optics. The optical properties of the first subgroup and second subgroup of the plurality of optics are different. The lighting device further includes a controller module configured to control at least two current signals supplied from a power source to each of the at least two subgroups of light-emitting semiconductor devices, respectively. The controller module is configured to modify the beam width and the peak intensity of the emitted beam of light by varying the magnitude of the respective at least two current signals.
