Dimmable external vehicle lighting and methods of use are provided herein. An example method includes determining environmental light intensity around a vehicle, determining a luminance of an external light of the vehicle, determining a difference in magnitude between the environmental light intensity and the luminance of the external light, and selectively adjusting the luminance of the external light based on the difference.

The present disclosure relates to a method for sanitization of a surface by emission of a plurality of sanitization wavelengths, and to a device for implementing the method. The method comprises emitting light using first LEDs configured to emit the sanitization wavelengths, receiving, by a circuit, a feedback signal from a light sensor indicating a light intensity received by the light sensor during the light emission, and controlling the first LEDs with the circuit based on the feedback signal.

Various examples relate to adjustable light sources. An example may include an apparatus including a light source to adjustably emit light toward a region of interest at least partially responsive to a control signal. The apparatus may also include a sensor to generate a signal indicative of an intensity of light sensed by the sensor in the region of interest. The apparatus may also include a wireless-communication equipment to broadcast a value that represents the intensity of light received by the sensor. The wireless-communication equipment may also receive a broadcast of a further value that represents an intensity of light in a further region of interest. The apparatus may also include a processor to adjust the control signal at least partially responsive to the further value. Related devices, systems and methods are also disclosed.

A portable lamp, preferably a headlamp, which is adapted to be worn or carried by a user, comprising: at least one light source, an AI unit, wherein the AI unit comprises an activity classification unit and a control unit, wherein said activity classification unit is able to automatically classify an activity which the user is currently carrying out without any manual setting by the user, wherein said control unit is adapted to control the beam of said at least one light source at least based on the classified activity of the user.

A Smart ANSI Microcontroller is provided to retrofit preexisting light fixtures. The preexisting light fixtures are configured with 5 pin or 7 pin ANSI receptacles. The Smart ANSI Microcontroller is configured to accept a variety of control signals and to control the power output of the driver of the preexisting driver of the luminaire in order to control the light output of the luminaire. The Smart ANSI Microcontroller is configured with a 5 pin or 7 pin ANSI male connector that is configured for mating engagement with the 5 pin or 7 pin female ANSI connector found in typical prior art luminaires, such as street lamps. The Smart ANSI Microcontroller allows for contemporary accessory light controllers to be utilized with the preexisting luminaires. The contemporary light controllers can be configured to connect to the Smart ANSI Microcontroller via wireless and/or wired connection.
