Light control system for use within a hospital environment
First Claim
1. A light control system for controlling lighting in a room within a hospital environment, the control system comprising;
- a controller having an input for receiving a first sensor signal indicative of at least one of a location and a movement of a clinical instrument, and an output for outputting at least a first control signal to a controllable light,wherein the controller is configured to generate the first control signal in response to the first sensor signal; and
a time-scheduler configured to at least one of delay the outputting and the generation of the first control signal,wherein the delay is set relative to a time of receipt of the first sensor signal.

Abstract
The invention relates to a control system (100) for an ambient light environment in a room in a hospital environment. The control system is configured to time and synchronize light effects of the ambient light environment (170, 190) in response to sensor signals (111-113) from patient location sensors (121) or other sensors (122,123) for detecting if a clinical instrument is activated, moved or taken into use or for detecting heart rate. Light effects may be used by the clinical personnel to improve quality and speed of the examination and to create a calming atmosphere for the patient. However, different light effects are required at different times and for different durations. Therefore, timing of the light effects relative to sensor signals may improve workflow and patient comfort.

8. A method for controlling lighting in a room within a hospital environment, the method comprising;
-
receiving a first sensor signal indicative of a location of at least one of patient, a clinical instrument and a clinical device; and generating a first control signal to a controllable light by use of a controller configured to generate the first control signal in response to receipt of the first sensor signal, wherein the generation or outputting of the first control signal is delayed relative to a time of receipt of the first sensor signal, and wherein the delay is controlled by a time-scheduler.
