Control device, wearable device and lighting system for light therapy purposes
First Claim
1. A lighting system for controlling a light source, the lighting system comprising:
- a wearable device including a light sensor, the wearable device being configured to detect at least one of an intensity and an amount of light a person has received from two different light sources with a first one of the two different light sources being a therapy light source and a second one of the two different light sources being a white light source, and configured to produce at least one value indicative of the detected at least one of the intensity and amount of light a person has received from the two different light sources;
a control unit operably coupled to the wearable device and configured to determine control signals to control intensity and color composition produced by the therapy and white light sources dependent on the at least one value received from the wearable device to compensate for a visible light deficiency, with the control unit being further configured to adjust the determined control signals that are dependent on the at least one value to provide a total desired amount of blue light by keeping an amount of blue light produced during nighttime below an amount required to compensate for the deficiency and correspondingly increasing the blue light produced during daytime to account for a reduced amount of blue light produced during the nighttime and thereby provide the total desired amount of blue light; and
an output for controlling the therapy and white light sources, operably coupled to the control device, wherein the output comprises a wireless transmitter for wirelessly transmitting the adjusted control signals to the therapy and white light sources.

Abstract
The control device for controlling a therapy light source including an input for receiving information on an intensity and/or amount of light a person has been exposed to from a wearable device that can connect to the control device via the input. The control device further includes an output for controlling at least one therapy light source that can be connected to the control device. A control unit of the control device is designed to control a connected therapy light source dependent on the information on the intensity and/or amount of light the person has been exposed to. A wearable device that is suited to operate in combination with the control device includes a light sensor for detecting an intensity of received light. It further comprises a storage unit connected to the light sensor for storing at least one value related to the measured intensity of the received light.

9. A lighting system for controlling a light source, the lighting system comprising:
-
a wearable device including a light sensor configured to detect an intensity of received light from each of two light sources, with a first one of the two light sources being a blue light source and a second one of the two light sources being a white light source and configured to produce at least one value indicative of the intensity of light a person has received from the two light sources, and a storage unit operably coupled to the light sensor for storing the at least one value related to at least the detected intensity of the received light from the two light sources; and a controller wirelessly coupled to the storage unit and the blue and white light sources and configured to determine control signals to control intensity and color composition produced by the blue and white light sources based on the at least one value to compensate for a visible light deficiency, with the control unit being further configured to adjust the determined control signals that are dependent on the at least one value to provide a total desired amount of blue light by keeping an amount of blue light produced during nighttime below an amount required to compensate for the deficiency and correspondingly increasing the blue light produced during daytime to account for a reduced amount of blue light produced during the nighttime and thereby provide the total desired amount of blue light based on the adjusted control signals. - View Dependent Claims (10, 11, 12, 13)

14. A lighting system for light therapy purposes, comprising:
-
a therapy light source and a white light source with each producing separate light; a control device configured to wirelessly control the therapy and white light sources; and a wearable device operably coupled to the control device, the wearable device including a light sensor configured to detect at least one of an intensity and an amount of light a person has received from each of therapy and white light and configured to produce at least one value indicative of the at least one of the intensity and amount of light a person has received from the therapy and white light sources, the control device including an input for receiving the at least one value from the wearable device; an output for wirelessly controlling the therapy and white light sources to compensate for a visible light deficiency, wherein the control device is configured to wirelessly communicate with the therapy and white light sources; and a control unit for controlling intensity and color composition produced by the therapy and white light sources dependent on the at least one value received from the wearable device, with the control unit being configured to adjust determined control signals that are dependent on the at least one value to provide a total desired amount of blue light by keeping an amount of blue light produced during nighttime below an amount required to compensate for the deficiency and correspondingly increasing the blue light produced during daytime to account for a reduced amount of blue light produced during the nighttime and thereby provide the total desired amount of blue light, wherein the output comprises a wireless transmitter for wirelessly transmitting the adjusted control signals to the therapy and white light sources. - View Dependent Claims (15, 16, 17, 18, 19, 20)
