Abstract
Light systems and light fixtures are described herein. In one embodiment, a light system may include a light fixture, a first diffuser attached to the light fixture, where the first diffuser and the light fixture define a cavity, a first LED producing ambient light within the cavity, and a second LED producing directional light in the cavity, where the first diffuser is adapted or configured to receive the ambient light and the directional light and emit the ambient light and the directional light external to the light system. In another embodiment, a light fixture may include a first LED subsystem including a first LED and a diffuser, the first LED subsystem adapted or configured to produce ambient light, a second LED subsystem including a second LED and a reflector, the second LED subsystem adapted or configured to produce directional light, where the directional light passes through the diffuser.
