Abstract
An operating room light fixture with a light fixture housing, in which at least one lighting unit with at least one light source is arranged, with a handle, which is arranged on a side of the light fixture housing facing the operating area, wherein the handle comprises a control element for setting and/or adjusting the luminous intensity of the light source.
Claims17
An operating room light fixture with actuating device, comprising:
- a first lighting unit having a first light source and an external reflector;
- a second lighting unit having a second light source and an internal reflector;
- a control unit for varying and setting the luminous intensity of the first light source and the second light source, wherein said first light source of said first lighting unit and said second light source of said second lighting unit are operatively interconnected by said control unit;
- and
- a single control element connected to said control unit such that a luminous intensity of the operating room light fixture is set between a minimum and a maximum of said first light source of said first lighting unit and said second light source of said second lighting unit within a control element actuation range according to a preset control curve by actuating said single control element.
2 more elements
An operating room light fixture, comprising:
- a light fixture housing;
- a first lighting unit with a first light source, said first lighting unit being arranged in said housing, said first lighting unit having a first lighting unit reflector radially outward of said first light source;
- a second lighting unit with a second light source, said second lighting unit being arranged in said housing with said second light source substantially coaxial with said first light source, said second lighting unit having a second lighting unit reflector radially outward of said second light source and radially inward of said first lighting unit reflector and directing emitted light axially outwardly;
- a control unit connected to said first lighting unit and said second lighting unit for controlling a luminous intensity of said first lighting unit and for controlling a luminous intensity of said second light unit;
- and
- a handle arranged on a side of the light fixture housing facing the operating area and substantially coaxial with said first light source and said second light source, said handle comprising a control element connected to said control unit with a single range of control for setting and/or adjusting the luminous intensity of the first light source and the second light source within a single luminous intensity range including a variable luminous intensity of said first light source and a variable luminous intensity of said second light source with said variable luminous intensity of said second light source superimposed on said variable luminous intensity of said first light source within said single range of control.

An operating room light fixture, comprising:
- a light fixture housing;
- a first lighting unit with a first light source, said lighting unit being arranged in said housing, said first lighting unit having a first lighting unit reflector radially outward of said first light source;
- a second lighting unit with a second light source, said second lighting unit being arranged in said housing with said second light source substantially coaxial with said first light source, said second lighting unit having a second lighting unit reflector radially outward of said second light source and radially inward of said first lighting unit reflector and directing emitted light axially outwardly;
- a control unit connected to said first lighting unit and said second lighting unit for controlling a luminous intensity of said first lighting unit and said second lighting unit;
- and
- a rotary element connected to said control unit for setting and/or adjusting the luminous intensity of the first light source and the second light source by rotation of said rotary element within a single control range to provide a single variable luminous intensity range incorporating a full variation of said first light source and a full variation of said second light source with said full variation of said second light source being superimposed on a variable or fixed intensity of said first light source within said single variable luminous intensity range, said rotary element comprising a handle arranged on a side of the light fixture housing facing the operating area and coaxial with said first light source and said second light source.
