LIGHTING SYSTEM FOR CREATING A BIOLOGICAL EFFECT
First Claim
1. A lighting system for creating a biological effect induced by light, the biological effect being a different effect than vision, and the lighting system comprising:
- at least one light source (1) for generating light with a varying spectrum, andat least one driver (2) for driving the lighting system (1) to, successively in time;
generate a first spectrum (S1) during a first period in time (T1),change the first spectrum (S1) into a second spectrum (S2) during a second period in time (T2), the second spectrum (S2) having the biological effect, andcontinue the second spectrum (S2) during a third period in time (T3), wherein a duration of the second period in time (T2) is selected in a range from 5 seconds to 30 minutes.

Abstract
A lighting system for creating a biological effect induced by light. The biological effect is a different effect than vision. The lighting system comprises a light source (1) to generate light with a varying spectrum, and a driver (2) to drive the light source (1) to successively in time: (i) generate a first spectrum (S1) during a first period in time (T1), (ii) change the first spectrum (S1) into a second spectrum (S2) during a second period in time (T2), wherein the second spectrum (S2) has the biological effect, and (iii) maintain the second spectrum (S2) during a third period in time (T3). The duration of the second period in time (T2) is selected in a range from 5 seconds to 30 minutes. The first spectrum (S1) may not have the biological effect or may have the biological effect to a smaller extent than the second spectrum (S2).

15. A method of driving a light source (1), the method comprising successively the steps of:
-
generating (1, 2) a first spectrum (S1) during a first period in time (T1), changing (1, 2) the first spectrum (S1) into a second spectrum (S2) during a second period in time (T2), the second spectrum (S2) having a biological effect induced by light generated by the light source (1), the biological effect being a different effect than vision, and continuing (1, 2) the second spectrum (S2) during a third period in time (T3), wherein a duration of the second period in time (T2) is selected in a range from 5 seconds to 30 minutes.
