Abstract

This invention relates to a lighting system for stimulating a user'"'"'s energy by emitting bluish wake-up light and tuning the bluish light towards a daytime-like white light.

Claims

1. A lighting system (100) for stimulating a user'"'"'s (104) energy, the lighting system comprising:

at least one light source (103), and

a control unit (102) for controlling the light emitted from the at least one light source (103),

wherein the controlling comprises the steps of instructing the at least one light source (103) to emit bluish wake-up light and tuning the bluish light towards a daytime-like white light.

2. A lighting system according to claim 1, wherein the bluish wake-up light has a wavelength range of 390 nm-470 nm, e.g. 410 nm-450 nm, 415 -425 nm, or 419 nm-421 nm.

3. A lighting system according to claim 1, wherein the at least one light source (103) is selected from:

Light-Emitting Diodes (LED),

fluorescent lighting,

incandescent lamps,

halogen lamps,

High-Intensity Discharge (HID) lamps, or

combinations of one or more of the above light sources.

4. A lighting system according to claim 1, wherein the bluish light is tuned towards the daytime-like white light over a given period of time manually selected by the user (104).

5. A lighting system according to claim 1, further comprising a sensor (201) adapted to be coupled to the control unit (102), wherein the tuning of the bluish light towards the daytime-like white light is initiated in response to a signal indicating the user'"'"'s (104) presence.

6. A lighting system according to claim 1, wherein the controlling further comprises the steps of emitting daytime-like light and tuning the daytime-like light to dusk-like/sunset-like light.

7. A lighting system according to claim 1, further comprising an activation unit (101) comprising a timer (105), the timer being adapted to receive an input of a start time and the activation unit being adapted to activate, in response to the received start time, the control unit to start the emission of bluish light.

8. A lighting system according to claim 7, wherein the timer (105) is further adapted to receive an input of an end time, the difference between the received start time and the received end time indicating the maximum period of time for tuning the bluish light towards the daytime-like white light.

9. Use of a lighting system as claimed in claim 1 in a humid environment.

10. Use of a lighting system according to claim 1, wherein the humid environment is a shower booth (200).

11. A method of stimulating a user'"'"'s energy, the method comprising the steps of:

providing (303) at least one light source, and

controlling (304) the light emitted from the at least one light source,

wherein the controlling comprises the steps of instructing the at least one light source to emit bluish wake-up light and tuning the bluish light towards a daytime-like white light.

12. A method according to claim 11, wherein, shortly before or immediately after the daytime-like white light has been reached, the light is made warmer by increasing the red-component intensity or reducing the blue component, or by a combination thereof.

13. A method according to claim 11, wherein the bluish light is tuned towards a daytime-like light in a continuous way.
