A lighting unit (100) for a medical luminaire (150) has a number of groups of LEDs (110, 110′, 110″) that are connected to a common planar printed circuit board (115). Each LED (112, 112′) of at least one of the groups (110, 110′) is associated with a respective optic (122, 122′) by which a respective LED-optic pair (120, 120′) is formed. The respective optics, based on the structure (328), specify a tilt angle (125) of a central light beam axis (124, 124′) of an emitted light beam of the LED optics pair in a tilt direction (627) of the respective LED optics pair. The tilt direction is defined such that the respective light beam axes of the emitted light beams of the LED optics pairs from the at least one group of LEDs are at least partially skewed in pairs with respect to one another.

A light emitting type capsule treatment tool for irradiating light with a specific wavelength required for photoimmunotherapy, includes a power receiving coil, a magnetic member, a light emitting member and a capsule. The power receiving coil is formed by winding a conductive wire and configured to receive electric power supplied from an external transmission antenna via a magnetic flux. The magnetic member is placed on an inner circumference of the power receiving coil. The light emitting member is configured to be supplied with electric power from the power receiving coil and to emit the light with the specific wavelength. The capsule houses the power receiving coil, the magnetic member and the light emitting member.

A smart flexible operating room lighting system with a control system utilizing artificial intelligence (AI) modules may be coupled to a wall, ceiling, or fixture of and mobile in a facility. The lighting system can modularly accommodate multiple illumination arms and incorporate microphones thereon, permitting the vocal control using the control system for hands free operations. The control system controls the movements of the illumination arms to desired positions and orientations via motor-driven actuators and position sensors thereon. The lighting system may include a speaker and a camera to facilitate two-way communications with a user via the control system to facilitate demonstrations for individuals undergoing tutelage in the facility. Further, a cover with a transparent front end may be provided to be slipped over the lighting system and securing through a cover fastener. Thus, the present invention provides reliable sanitary measures while facilitating efficient operations via the smart flexible illumination arms.

This disclosure relates to a surgical lighting device comprising a shell (12), a plurality of light sources (24) coupled to the shell, and a closure plate (18) for closing the lighting device by allowing light to pass through. The closure plate comprises a plurality of lens elements, each lens element being configured to collect and focus light from a corresponding light source to generate a light spot of a predetermined diameter located at a predetermined distance from the lighting device. In order to simplify the structure of the lighting device, the light sources and the cover plate are arranged in such a way that the light beams coming from the light sources and received by the associated lens elements arrive at the lens elements without substantial reflection or deflection. The closure plate therefore comprises all the optics necessary for collecting and focusing the light from the light sources.

It is provided an illumination apparatus, comprising a first light source mounted on a board emitting first light having a first wavelength spectrum; a second light source mounted on the board emitting second light having a second wavelength spectrum; a phosphor layer converting at least a part of at least one of the first light and the second light into first converted light and second converted light, respectively; wherein the phosphor layer emits a remaining part of the first light, a remaining part of the second light, the first converted light, and the second converted light; the phosphor layer is in contact with the first and second light sources and continuous on the first and second light sources, and on a path on the board connecting the first and second light sources; the phosphor layer and the board surround the first light source and the second light source.

A light-receiving unit containing four optical sensors arranged crosswise and a light-shielding body containing four through-holes confronting light-receiving surfaces of the optical sensors, and a tilt adjustment mechanism containing first and second movable bodies which are mounted on first and second rotation shafts arranged on a same plane to cross at right angles are provided.
