Unintended current flow or plasma discharge has been observed in known illuminated electrosurgical devices having a metallic tubular heat sink surrounding a conductive electrode and an illumination element, and having a distal outer edge that abuts against the light emitting element. An insulating, shielding or other isolating element that prevents or discourages unintended plasma formation between the distal outer edge and nearby patient tissue can reduce the potential for tissue damage to a patient or injury to a surgeon.

A method and apparatus for improving the optical properties of an LED using a retroreflector element. A light emitting apparatus includes a substrate, at least one light emitting device attached to the substrate and including an outer primary light emitting surface through which substantially all light is emitted, and a retroreflector assembly attached to the substrate. The retroreflector assembly includes a proximal surface adjacent to the substrate, a distal surface spaced away from the substrate, and a retroreflective portion arranged between proximal surface and the distal surface. A distance from the distal surface to the substrate is less than or equal to a distance from the outer primary light emitting surface to the substrate.

A lighting apparatus including a controller, an LED driver, and an LED luminaire including: a first light emitting unit for general lighting; and at least one of a second light emitting unit to cause production of vitamin D upon irradiation, a third light emitting unit to cause production of a cell activating substance upon irradiation, and a fourth light emitting unit to sterilize pathogenic microorganisms, in which the controller controls the LED driver to change a color temperature of the first light emitting unit in accordance with a change in a color temperature of sunlight, and to change an irradiance of light emitted from at least one of the second, third, and fourth light emitting units according to time, and the LED luminaire includes a greater number of the first light emitting unit than any of the second, third, and fourth light emitting units.

A lighting device configured to deactivate pathogens in an environment. The lighting device includes a housing, means for mounting the housing to a surface in the environment, one or more first light-emitting elements arranged in the housing and configured to each produce disinfecting light having a wavelength in a first range of wavelengths, and one or more second light-emitting elements arranged in the housing and configured to each produce disinfecting light having a wavelength in a second range of wavelengths different from the first range of wavelengths. The disinfecting light produced by the first light-emitting elements and the disinfecting light produced by the second light-emitting elements mix to form a combined light, the combined light being visible light other than white light.

An apparatus for surgical lighting is disclosed. The apparatus includes a light emitting element formed with a light source encapsulated within an outer layer. The outer layer includes a biocompatible material. A power supply is coupled to the light source. The apparatus includes an actuating mechanism that controls power from the power supply to the light source to emit light along a surgical area. The light emitting element provides enhanced illumination and other surgical advantages.
