    摘要： An illumination assembly includes a light-emitting element that emits light over a light-source numerical aperture and an elongated light-guiding element including opposed incident and emission ends between which ends light propagates by total internal reflection. The light-guiding element includes along a portion of its length a numerical-aperture alteration taper having opposed small and large ends exhibiting, respectively, a small-end numerical aperture and a large-end numerical aperture lower in magnitude than the small-end numerical aperture. The alteration taper is oriented such that the small end is more proximate the incident end than the large end. The incident end is in light-collecting proximity and alignment with the light-emitting element such that light emitted from the light-emitting element over the small-end numerical aperture and received into the small end of the alteration taper is emitted from the emission end of the light-guiding element at an emission numerical aperture lower in magnitude than the small-end numerical aperture.

    摘要： A light-emitting wand is configured for selective cooperative coupling with a handset. The wand extends between longitudinally opposed wand-body proximal and distal ends, the distal end being configured to retain a light-emitting element. Extending in mutual parallel alignment between the proximal and distal ends are electrically-conductive first and second core members. Each core member has, at the distal end, a light-source contact configured for electrical contact with a respective pole of the light-emitting element and, at the proximal end, a power-source contact configured for electrical contact with a respective terminal of an electrical-power source. The core members are maintained in mutual electrical isolation and overmolded with an electrically-insulative material through which the power-source contacts are exposed in order to enable selective electrical connection with electrical-power source terminals. In addition to carrying electrical current, the core members serve as heat sinks to dissipate the thermal output of the light-emitting element.
