Claim of US Patent No. 11,071,187


15. A circadian entrainment enhancement device, comprisinga housing;
a first directional light source;
a first tunable driver;
a first memory module;
a first computational module;
a light sensor;
wherein:the housing houses the first directional light source, the first tunable driver, the first memory module, the first computation module, and the light sensor;
the first tunable driver is configured to drive the first directional light source to generate a variable first light output,
the first directional light source has a first melanopic ratio R1>0.80,
the light sensor is configured to measure a vertical lux LA of an ambient light with respect to the device,
the first memory module is configured to store Illuminating Engineering Society (IES) data of the first directional light source and configuration information used by the first computational module,
the first computational module is configured to set a melanopic ratio RA1 of the ambient light of the device,
the first computational module is configured to set a first equivalent melanopic lux (EML) target to EMLT1,
the first computation module is configured to calculate a first target lux LT1 of the first directional light source using the first melanopic ratio R1, the vertical lux LA of the ambient light, the melanopic ratio RA1 of the ambient light, the first EML target EMLT1, and the IES data of the first directional light source such that a combination of an EML from the ambient light and an EML of the first directional light source at a 0-degree lighting zone approximates the first EML target EMLT1,
the first computation module is further configured to adjust the first tunable driver to set the light output of first directional light source to be the first target lux LT1 at the 0-degree lighting zone at zero distance, and
the device is configured to shine a light of the first directional light source horizontally to eyes of the user.
