Abstract
An operating lamp includes a plurality of illumination elements arranged in discrete groups. The illumination elements include at least one white illumination element, adapted to emit a white light, and multiple colored illumination elements, each adapted to emit a non-white, colored light. The operating lamp also includes a controller in communication with the illumination elements, and one or more storage devices configured to communicate with the controller. Each of the storage devices is associated with one or more of the groups of illumination elements, and each of the storage devices contains a set of power values for each associated group. The controller is configured to control illumination of each group of illumination elements individually, based on the associated power values.
Claims25
An operating lamp comprising:
- a plurality of illumination elements arranged in a plurality of discrete groups, the illumination elements including
- at least one white illumination element adapted to emit a white light, and
- multiple colored illumination elements, each adapted to emit a non-white, colored light;
- a controller configured to communicate with the illumination elements;
- and
- multiple storage devices configured to communicate with the controller, each of the storage devices being associated with one or more of the groups of illumination elements, and each storage device containing a predetermined set of power values for each associated group of illumination elements,
- wherein the controller is configured to control illumination of each group of illumination elements individually based on the associated power values to produce a predetermined nominal output, the power values comprising calibrated data corresponding to a set of nominal operating values of the operating lamp, the plurality of illumination elements together defining a light emitting surface, at least one of the nominal operating values corresponding to a desired distribution of light intensity over the emitting surface, and the distribution of light intensity having a lighting characteristic that corresponds to a particular operating environment.

An illumination method comprising:
- delivering a set of calibrated power values from a storage device of each of a plurality of lighting modules to a central controller;
- individually controlling one or more illumination parameters of each of a plurality of groups of illumination elements with a corresponding set of the calibrated power values that correspond to a desired distribution of light intensity over an emitting surface, to produce an emitted light having a predetermined nominal output value, the distribution of light intensity having a lighting characteristic that corresponds to a particular operating environment;
- and
- illuminating an operating environment with the illuminated light.
1 more element
A method comprising:
- arranging a plurality of illumination elements in a plurality of discrete groups, each discrete group having an associated storage device;
- applying a flow of electrical current to each group of illumination elements to cause the illumination elements to emit a light;
- measuring a lighting parameter of the emitted light;
- adjusting the flow of electrical current to at least one of the groups such that the measured lighting parameter substantially reproduces a predetermined nominal operating value that corresponds to a desired distribution of light intensity over an emitting surface, the distribution of light intensity having a lighting characteristic that corresponds to a particular operating environment;
- and
- recording a power value for each of the plurality of discrete groups on the respective storage devices associated with the groups, wherein the recorded power value corresponds to a strength of the flow of electrical current through the associated group when the measured lighting parameter substantially reproduces the predetermined nominal operating value.

An operating lamp comprising:
- a plurality of lighting modules each comprising:
- a plurality of LEDs arranged in a plurality of discrete groups and including:
- at least one warm white LED,
- at least one cool white LED,
- at least one cyan colored LED, and
- at least one blue colored LED;
- and
- one or more storage devices, wherein each group of illumination elements is associated with a corresponding one of the storage devices, and wherein each storage device contains a set of calibrated power values for each associated group;
- a controller configured to communicate with each of the storage devices;
- and
- a user interface configured to communicate with the controller and operable to select between a plurality of discrete output settings that correspond to a desired distribution of light intensity over an emitting surface, the distribution of light intensity having a lighting characteristic that corresponds to a particular operating environment,
- wherein the controller is configured to control illumination of the discrete groups of LEDs individually, based on the corresponding power values in combination with input from the user interface.
