A light-collecting unit having an inverted pyramid shape is described. The light-collecting unit has one or more outer light-collecting panel facing inward. The light-collecting unit also includes a first plurality of inner, light-collecting panels facing outward and a second plurality of inner, light-collecting panels facing inward. A flower base is configured to support the first plurality of inner, light-collecting panels and the second plurality of inner, light-collecting panels. The first plurality of inner, light-collecting panels is disposed on an outer facing side of the flower base and the second plurality of inner, light-collecting panels is disposed on an inner facing side of the flower base. The light-collecting unit may also include a light emitting element, such as an LED or fiber optic cable end. The light emitting element may provide infrared light to the light-collecting unit. The light emitting element may provide the light using pulse-wave modulation.
