A surgical lamp for illuminating a surgical field on a human body is provided. The surgical lamp comprises a control device (4), a lamp body (1) comprising several illuminants (3) with one respective light ray (I, II, II′) directed to the surgical field, and a 3D sensor (6) for detecting a spatial position of at least one object, and a device for switching on and off and dimming the illuminants (3), wherein the control device (4) controls the devices for switching on and off and dimming the illuminants (3), the 3D sensor (6) detects the spatial positon of the at least one object and transmits corresponding data to the control device (4), and the control device (4) is configured to control the illuminants (3) according to the spatial position of the at least one object.

An operating room lighting system, which comprises a lighthead support for a lighthead with a plurality of light elements, especially LED light elements, for generating a light field on an object to be illuminated, as well as adjustment elements for controlling features of the lighting system, especially for controlling features which modify a light field generated by the lighthead, said adjustment elements comprising a portable pointing device for controlling the lighting system by means of a pointing beam by the action of a lighting system operator. In the invention, the portable pointing device further comprises projection elements for projecting adjustment instructions on or around a light field generated by the pointing device and/or on a light field generable or generated by the lighthead.”

A lighthead for operating room service, said lighthead comprising a plurality of light sources, preferably LED elements, for generating a light field on a site to be illuminated, as well as adjustment elements for modifying features of said light field, said adjustment elements comprising a user interface for modifying features of the light field by the actions of a lighthead operator, characterized in that the user interface further comprises projection elements for projecting adjustment instructions on or around the light field. A method utilizing the lighthead for projecting adjustment instructions is presented.

The present invention provides a surgical illuminator. The surgical illuminator includes a base, a guide barrel, a cam barrel, a grip ring, a lens barrel, a printed circuit board having three light emitting diodes, a triple aspheric lens, a first lens mask, a triple double-convex lens and a triple double-convex lens. Methods of using the surgical illuminator are also provided.

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 cordless, battery powered lighting device is disclosed which is configured to be removably installed on a distal end portion of a handheld electrosurgical instrument, and once the lighting device is installed on the distal end portion of the instrument, light automatically projects from the lighting device along the longitudinal axis of the surgical instrument.

A lighting device, having: a first light irradiation unit including a first concave reflecting mirror and a first light source provided within the first concave reflecting mirror; and a second light irradiation unit that has a second concave reflecting mirror that is smaller than the first concave reflecting mirror and a second light source provided within the second concave reflecting mirror, the second light irradiation unit being disposed more to the light irradiation direction side than the first light source, and being disposed so that the optical axes of the first concave reflecting mirror and the second concave reflecting mirror are the same.

The present application relates to a surgical light for illuminating an operating area, including a housing-like light body that accommodates at least a first and a second light unit and including a first power supply line that is electrically connected to the first light unit in order to feed electric current from a first voltage source to at least one light source of the first light unit, wherein the second light unit of the light body has at least one further light source and is connected to a second power supply line, that is separate from the first power supply line, by means of which second power supply line a second voltage source can be electrically connected to the second light unit.

Aspects of the present application relate to a bypass switch for a lamp, such as a surgical or diagnostic lamp. When activated, the bypass switch may act to allow electric power to bypass elements of a control board so that the electric power is provided to the plurality of lamp elements.

A system and method for creating a trompe-l'oeil skylight in a ceiling where a light emitting image of the sky is provided in a structure configured to emulate a skylight frame, including an embodiment of a unified non-rectangular sky image area in a substantially rectangular fixture which mount as a single unit into a substantially rectangular hole in a ceiling.
