Light fixtures and methods

A light fixture comprising:

• a control element configured to vary a color point of light exiting from a first portion of a sidewall of a light fixture and a color point of light exiting from a second portion of the sidewall of the light fixture, wherein the sidewall defines a space, and the sidewall extends around the space;
• a first light engine that emits light that has x, y color coordinates which define a point on a 1931 CIE Chromaticity Diagram which is within an area with vertices having x, y coordinates of (0.37, 0.34), (0.35, 0.38), (0.15, 0.20), and (0.20, 0.14);
• and
• said sidewall, wherein from each of the first and second portions of the sidewall, light that has x, y color coordinates which define a point on a 1931 CIE Chromaticity Diagram which is within an area with vertices having x, y coordinates of (0.29, 0.32), (0.32, 0.29), (0.41, 0.36), (0.48, 0.39), (0.48, 0.43), (0.40, 0.41), and (0.35, 0.38) exits.

A light fixture comprising:

• a control element configured to vary a color point of light exiting from a first portion of a sidewall and a color point of light exiting from a second portion of the sidewall based on the time of day, wherein the sidewall defines a space, and the sidewall extends around the space;
• a first light engine that emits light that has x, y color coordinates which define a point on a 1931 CIE Chromaticity Diagram which is within an area with vertices having x, y coordinates of (0.37, 0.34), (0.35, 0.38), (0.15, 0.20), and (0.20, 0.14);
• and
• said sidewall, wherein from each of the first and second portions of the sidewall, light that has x, y color coordinates which define a point on a 1931 CIE Chromaticity Diagram which is within an area with vertices having x, y coordinates of (0.29, 0.32), (0.32, 0.29), (0.41, 0.36), (0.48, 0.39), (0.48, 0.43), (0.40, 0.41), and (0.35, 0.38) exits.

A light fixture, comprising:

• a control element;
• a first light engine;
• and
• a second light engine,
• the control element configured to vary a circadian stimulus value of light exiting from a light fixture, said circadian stimulus value equal to a percentage of melatonin suppression when exposed to the light exiting from the light fixture,
• the first light engine emits light that has x, v color coordinates which define a point on a 1931 CIE Chromaticity Diagram which is within an area with vertices having x, y coordinates of (0.37, 0.34), (0.35, 0.38), (0.15, 0.20), and (0.20, 0.14);
• and
• the second light engine emits light that has x, v color coordinates which define a point on a 1931 CIE Chromaticity Diagram which is within an area with vertices having x, y coordinates of (0.29, 0.32), (0.32, 0.29), (0.41, 0.36), (0.48, 0.39), (0.48, 0.43), (0.40, 0.41), and (0.35, 0.38).
