Abstract
Techniques for high-resolution dimming include a light fixture having a plurality of light sources arranged in a plurality of groups, wherein each group comprises one or more light sources. The plurality of groups are controlled so that each of the groups is repeatedly switched on and off according to a repeating pattern, the repeating pattern including at least three different combinations of which of the plurality of groups is switched on and which of the plurality of groups is switched off. Each of the at least three different combinations is repeated at least once every 1/10 s.

A method of operating a light fixture comprising a plurality of light sources arranged in a plurality of groups, wherein each group comprises one or more light sources, the method comprising:
- controlling the plurality of groups so that each of the groups is repeatedly switched on and off according to a repeating pattern, the repeating pattern including at least three different combinations of which of the plurality of groups is switched on and which of the plurality of groups is switched off,
- wherein each of the at least three different combinations is repeated at least once every 1/10 s.
A light fixture system comprising:
- a light fixture comprising:
- a plurality of light sources arranged in a plurality of groups, wherein each group comprises one or more light sources, and
- a controller,
- wherein the controller is configured to control the plurality of groups so that each of the groups is repeatedly switched on and off according to a repeating pattern, the repeating pattern including at least three different combinations of which of the plurality of groups is switched on and which of the plurality of groups is switched off, and
- wherein each of the at least three different combinations is repeated at least once every 1/10 s.
A non-transitory computer readable medium storing instructions that, when executed by a controller of a light fixture system comprising a light figures having a plurality of light sources arranged in a plurality of groups, wherein each group comprises one or more light sources, configure the controller to perform the steps of:
- controlling the plurality of groups so that each of the groups is repeatedly switched on and off according to a repeating pattern, the repeating pattern including at least three different combinations of which of the plurality of groups is switched on and which of the plurality of groups is switched off,
- wherein each of the at least three different combinations is repeated at least once every 1/10 s.
