Abstract

See full text

A portable floor light emits light along a surface of the floor and at a shallow emitted angle to provide lighting during dark conditions. The housing of the portable floor light has a curved light emitting edge with a light emitting gap to project light across a wide area of the floor. The light emitting edge may be an arc that extends 60 degrees or more, such as 90 degrees or 180 degrees for example. The portable floor light has a motion sensor and ambient light sensor that provide input to a controller. The light will be activated when motion is detected and the ambient light is below a threshold value, or in darker conditions. The light emitted may have a wavelength no less than about 570 nm to avoid disrupting the circadian rhythms of people when they get up in the night, for example.
