A headlight device includes a headband for encircling a head of a wearer, a padding system having a pad attached to at least a portion of the headband, the pad including a first layer and a second layer. The first layer includes a first cushioning material having a first durometer and or the second layer includes a second cushioning material having a second durometer, or the first layer is perforated in a first perforation pattern and or the second layer is perforated in a second perforation pattern.

In one aspect, a handheld lighting system is disclosed, which comprises a handheld housing extending from a proximal end to a distal end, and a light module disposed at least partially in the housing. The handheld lighting system further includes a removable and replaceable power module that is coupled to the housing (e.g., it is at least partially disposed within the housing) and is electrically coupled to the light module, e.g., through a pair of electrical leads, for providing electrical power thereto. Light intensity from the light module may be controlled from a knob on the power module. Various adapters can allow the lighting system to attach to a multitude of medical, industrial, dental or veterinary endoscopes or other instruments.

Head wearable devices and methods are disclosed where a head wearable device includes a headpiece including a headband with a top strap, a first housing attached to an outer surface of the top strap of the headband, a depth adjuster attached to the first housing wherein the depth adjuster is configured to change a depth of the headpiece, and a headband adjuster configured to change a circumference of the headpiece.

Embodiments include a lighting assembly includes an elongate gasket body formed of a resilient, optically transmissive material. The gasket body includes a light source cavity at least partially defined by a light transmission portion and an attachment channel configured to attach the gasket body to a mount. A light source is disposed in the light source cavity. Other embodiments include securement ring including a clamp portion and a lighting assembly portion. The clamp portion includes first and second segments, each being semiannular in shape and curving between first and second ends, the first end of the first segment coupled to the second end of the second segment and the second end of the first segment coupled to the first end of the second segment to collectively form an aperture. The lighting assembly portion includes a first and second segments, each being semiannular in shape and including a light source.

An implantable light generation arrangement for an optical or optical/electrical stimulation system includes a light source having an emission surface, wherein the light source is configured to generate light and emit the light from the emission surface; an optical waveguide having a first end and a core; a ball lens disposed between the light source and the optical waveguide and configured to receive the light emitted from the light source and direct the light onto the core at the first end of the optical waveguide; and a fixture holding the light source, optical waveguide, and ball lens in a fixed arrangement.

Lighting devices are disclosed for use with handheld surgical instruments, along with holsters for supporting surgical instruments with lighting devices thereon and kits containing surgical instruments and lighting devices.

An elliptical lens comprises a lens body having a proximal section and a distal section. The proximal section has at least one input surface for receiving light from a light source and the distal section has at least one output surface through which light exits the lens body. The proximal section further comprises a substantially elliptical peripheral surface receiving at least a portion of the light entering the lens body via the at least one input surface and directing at least some of the received light via total internal reflection to the distal section such that at least a portion of the light directed to the distal section exits the lens body through said at least one output surface. Optical assemblies having said elliptical lens may be embedded in medical devices such as endoscopes to provide efficient illumination.

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 surgical light source system for cooling high-powered arthroscopic light emitters. The surgical light source system includes a housing having a proximal end and a distal end with a tube connected to the proximal end. The system also includes a light source at the distal end of the housing which is connected to a remote power source. The system has a plurality of fins extending around the light source within the housing and a remote fan connected to the tube. The remote fan is adapted to draw air across the fins, forming a heatsink within the housing.
