Abstract
A circadian entrainment enhancement device includes a housing, a first directional light source, a second directional light source, and a driver. During daytime, the driver turns on the first directional light source with a high melanopic ratio to enhance the daytime circadian entrainment of a user. During nighttime, the driver turns on the second directional light source with a low melanopic ratio to enhance the nighttime circadian entrainment of a user. A more advanced version of the present disclosure uses a light sensor, a memory module, and a computation module to calculate the necessary light output of the device by factoring the ambient light level into consideration. An even more advanced version of the present disclosure uses a distance sensor to adjust the light level of the light sources according to the distance between the device and the user.
