Abstract: Systems, vehicles, and methods for controlling light are provided. In an exemplary embodiment a vehicle with a cabin includes a light senor positioned within the vehicle, where the light sensor is configured to send a light intensity signal. A lamp module is positioned within the vehicle, where the light sensor is in communication with lamp module. The lamp module is configured to trigger a darkness lighting scheme when the light intensity signal is at about a darkness set value or less. A lamp is positioned within the cabin, where the lamp is in communication with the lamp module. The lamp is configured to emit a darkness spectrum when the lamp is activated and when the lamp module triggers the darkness lighting scheme. The darkness spectrum has a maximum illumination wavelength less than about 555 nanometers.

Abstract: An edge-lit reading lamp for an automobile is disclosed. The edge-lit reading lamp includes a housing having an open end and one or more sidewalls and a plurality of light emitting diodes (LEDs) disposed along the one or more sidewalls of the housing. The plurality of LEDs are configured to emit visible light, where the visible light includes blue visible light. The edge-lit reading lamp also includes a light guide plate surrounded by the plurality of LEDs and a diffuser plate positioned to receive the visible light emitted by the plurality of LEDs. The edge-lit reading lamp also includes anti-glare plate having an anti-glare plate having a plurality of light scattering microstructures disposed along a surface of the anti-glare plate that are oriented to face away from the visible light generated by the plurality of LEDs.
