A head-mountable light includes a user-adjustable spot size. Light from an LED travels through beam-forming optical elements supported at the front opening of a housing to form a spot of light at a working distance. An adjustable iris, situated between the LED and the beam forming optical elements, enables a user to adjust the iris and vary the size of the aperture and the spot size of the light at the working distance. The manually operated iris size control may comprise a rotatable ring on the exterior of the housing, and the plurality of beam-forming optical elements may comprise a singlet lens followed by a doublet lens. The light from the LED strikes the beam-dispersing element directly without an intervening condensing optical element (i.e., condensing lens). The assembly further includes a mechanical connector adapted to couple the housing to a pair of eyeglass frames, headband or other head-worn structure.

Head-mounted accessories for surgeons and medical/dental practitioners are equipped with no-touch controls including, in different embodiments, passive and active infrared detection, voice operation, and capacitive proximity control. Compared to infrared, capacitive proximity control may be more omni-directional, whereas IR, particularly active IR, tends to be more effective in a cone of operation. Compared to voice activation, capacitive sensing is less expensive and less prone to false activation based upon ambient noise or other voices. The invention may be used to control other medical/dental accessories such as a head-mounted video camera, in which case the controller is further operative to at least turn the video camera ON or OFF. More preferably, a controller is additionally operative to control the focus or zoom of the video camera in accordance with touch-free commands.

An air removal light device comprising a movable task light with an air suction channel having an inlet for evacuating air from the area below the task light that is between a practitioner and a patient/client. The device includes a body with an outer edge and bottom surface having at least one lamp. An air suction channel is created around the body by positioning an outer wall around the body, with at least one air inlet located adjacent the bottom surface of the body. The air suction channel has an air outlet which is connected to a vacuum hose and vacuum system to remove air from the area below the light. The removed air is transported through a filter to remove pathogens and particulate matter before being returned to the room or exhausted.

According to one embodiment, an illumination device includes a plurality of light emitting elements and a plurality of reflectors. The plurality of reflectors include at least one first reflector and at least one second reflector. The first reflector is provided corresponding to the first region at the center and is provided so that the corresponding light emitting element is positioned within a focal region in the vicinity of a focal point. The second reflector is provided corresponding to the second region, has an angular eccentricity so as to collect light on one region on the optical axis, and is provided so as to be positioned within a margin region in which one of the corresponding light emitting elements is provided at a position farther away than a second focal region in the vicinity of the focal point.

A lighting element is disclosed that provides a projection of light forming a substantially uniform bright light on a surface a known distance from the lighting element. The lighting elements includes a dome lens that is removably positioned on a light source, such that the light source is retained at a location within a focal length of a projection lens and at or within a focal length of the dome lens. The dome lens magnifies the light outputted by the light source, such that the projected light is brighter than the light generated by the light source.

A light assembly is configured to selectively illuminate an operating region in a surgical suite. The assembly comprises a plurality of lighting modules comprising a plurality of light sources configured to emit light. The assembly further comprises at least one imager configured to capture image data disposed in at least one of the lighting modules. An articulating head assembly is configured to support each of the lighting modules. The articulating head assembly comprises a plurality of actuators configured to rotate each of the lighting modules about a first axis and a second axis. The assembly further comprises a controller. The controller is configured to scan the image data for at least one region of interest comprising at least one of a shaded region and a contaminated region.

A user-wearable illumination assembly comprising eyeglass frames supporting a pair of lenses, a mounting structure on a bridge of the eyeglass frames, a headlamp removably coupled to the mounting structure, a battery housing removably coupled to the headlamp, and a battery inside the battery housing.

Head-mounted accessories for surgeons and medical/dental practitioners are equipped with no-touch, hands-free controls. A voice-activated headlamp includes a controller operative to send a signal to control a light source in accordance with a voice command received through an integrated or remote microphone. The voice command and control may be speaker-dependent or speaker-independent, and the head-mounted unit may include an interface to a computer for voice-command training or other purposes. The head-mounted unit includes a memory for storing the voice commands. The invention may be used to control other medical/dental accessories such as a head-mounted video camera, in which case the controller is further operative to at least turn the video camera ON or OFF. More preferably, a controller is additionally operative to control the focus or zoom of the video camera in accordance with a voice command.

A system includes a housing assembly having a top, side, middle, and bottom portions, a pair of hollow, tubular, elongated members having a top and a bottom end, the top portion of the housing assembly attached to the bottom end of the elongated members, the top end of the one or more elongated members having a brackets configured and arranged to mount to an overhead surface area, one or more ambient lighting assemblies attached to side portions and top portion of the housing assembly to provide general lighting, each ambient lighting assembly including an ambient housing and fluorescent bulbs, a horizontal tracking rail suspended attached to a bottom portion of the housing assembly, the tracking rail extending along a portion of the housing assembly, a carriage mechanism slidably engaging the tracking rail, and an intra-oral light assembly connected to the carriage mechanism.

A unit includes a rail system having a trolley and first and second hook rails that are configured to mate with corresponding portions of a mounting board secured to a ceiling, a length between the first and second hook rails approximately equal to a width of the mounting board to insure a snug fit, an arm system configured to link to the rail system and having an upper tube section, a middle tube section and a lower tube section, an end of the upper tube section including slip ring wire connections to enable the upper tube section to rotate within the rail system, and an illumination unit configured to link to the lower tube section and having an end of the lower tube section including slip ring wire connections to enable the illumination unit to rotate with respect to the lower tube section.
