SCENE SETTING CONTROL FOR TWO LIGHT GROUPS
First Claim
1. A lighting system (200) comprising:
- light sources (220) configured to provide light; and
a controller (210) configured to divide the light sources (220) into a focus group (310) including focus light sources for providing main light and a surrounding group (320) including surrounding light sources for providing background light;
wherein the focus light sources have individual focus intensity levels related to each other according to a first relationship, and the surrounding light sources have individual surrounding intensity levels related to each other according to a second relationship; and
change a ratio of the focus group to the surrounding group without changing the first relationship and the second relationship.

Abstract
A lighting system (200) includes light sources (220) configured to provide light; and a controller (210) configured to divide the light sources (220) into a focus group (310) including focus light sources for providing main light and a surrounding group (320) including surrounding light sources for providing background light. The focus light sources have individual focus intensity levels related to each other according to a first relationship, and the surrounding light sources have individual surrounding intensity levels related to each other according to a second relationship. The controller (210) may be further configured to change a ratio between the focus and surrounding groups without changing the first and second relationships, such as by interpolation or multiplying by a factor at least one of the individual focus intensity levels and the individual surrounding intensity levels. The controller (210) may also be configured to change the total intensity without changing the ratio, and the first and second relationships.
