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.

A LED light fixture having a mixture of red and white LEDs, as well as any combinations of UVA, UVB, UVC LEDs. The ratio of outputs from these LEDs may be adjusted to achieve a desired germicidal effect. The light fixture is liquid-cooled using a cooling tube that directly cools the power supply and the LED flexible printed circuit.

A medical headlamp headband assembly, having a preferred orientation relative to a wearer's head, and comprising a closed form headband, adapted to encircle a human head horizontally, thereby defining a head-facing side and having a tightness adjustment feature in a rear central location relative to a wearer's head when the headband assembly is worn in its preferred orientation. A tightness adjustment subassembly, at a central rear location, is opposed to the front location. A resiliently deformable wing-set is supported by the headstrap subassembly on the head-facing side, about the tightness adjustment subassembly and including a central part and two wings, each extending laterally outwardly from the central part. Each wing extends forward as it extends laterally from the central part, to contact the wearer's head at a rear side location, thereby holding the tightness adjustment assembly back from the wearer's head.

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.

A system to provide circadian-friendly lighting for nighttime hospital care comprising a lighting module and a transmitter tag that interface wirelessly wherein the lighting module comprises red-shifted light spectra, which is proven to be less disruptive to melatonin production than current blue-shifted hospital lighting; wherein the light output of the devices is modulated by the proximity of a tag to the device, with light intensity increasing with closer proximity between these two components and decreasing with increased distance, thereby providing hands-free lighting to caregivers in the specific locations where they need light to perform care tasks.

The present disclosure relates to an eyewear phototherapy device for providing skin cosmetology to the skin surrounding the eyes. The device includes a main spectacle frame having a left supporting member and right supporting member, each including at least one housing assembly extending outward from the each supporting member and facing towards the inner portion of the supporting member. Each of the housing assemblies includes an LED light board, attached to the inner side of the respective housing assembly, which is adapted to emit light energy, a transparent silicone cover attached on the LED light board for protecting direct contact between the LED light board and human skin, a protective element which is adapted to spread the LED emissions around a human eye and provide protection to the human eye from the LED emissions.

Touch-free lighting systems are described. In one embodiment, a touch-free lighting system may include a light, a battery housing, a pod coupled to the light and the battery housing, and a touch-free sensor coupled to the pod. The touch-free sensor may be configured to adjust a brightness of the light when activated. Methods of operating a touch-free lighting system are described. In one embodiment, a method may include adjusting a brightness of a light by activating a touch-free sensor coupled to the light.

A head wearable device includes a headpiece, a housing attached to the headpiece, a luminaire attached to the headpiece, the luminaire including a luminaire housing and at least one light source located within the luminaire housing, a duct system connecting the luminaire to the housing, a ball joint rotatably connecting the duct system to the luminaire, and an air moving device configured to induce a cooling air flow through an inlet in the luminaire housing, through the heatsink, through the ball joint, through the duct system, and out of an exhaust in the housing attached to of the headpiece.

A wearable medical device includes a frame and a lens coupled to the frame. The lens is configured to be positioned proximate eyes of a user. At least one lamp device is coupled to the frame. The at least one lamp device emits light forward from the frame. A controller activates and controls the at least one lamp device.

A lighting assembly includes a light transmissive substrate extending along a length and including a light emission portion including opposed first and second major surfaces spaced apart from one another in a thickness direction, an inner edge surface extending between the first and second major surfaces in the thickness direction, and an outer edge surface opposed the inner edge surface and extending in the thickness direction. An extension portion extends from the light emission portion proximate the second major surface in the thickness direction. A light source is attached to the extension portion. A light head includes a housing, a primary light source attached to the housing, and the lighting assembly as an auxiliary lighting assembly. The housing includes a channel in which the auxiliary lighting assembly is retained.
