A two-way load control system comprises a power device, such as a load control device for controlling an electrical load receiving power from an AC power source, and a controller adapted to be coupled in series between the source and the power device. The load control system may be installed without requiring any additional wires to be run, and is easily configured without the need for a computer or an advanced commissioning procedure. The power device receives both power and communication over two wires. The controller generates a phase-control voltage and transmits a forward digital message to the power device by encoding digital information in timing edges of the phase-control voltage. The power device transmits a reverse digital message to the controller via the power wiring.

The invention provides a method for managing image data in an automotive lighting device. This method includes providing a first image pattern, which is sent to a light module, and a second image pattern. A difference pattern is generated by subtracting the second image pattern from the first image pattern and this difference pattern is sent to the light module, so the light module is able to reconstruct the second image pattern from the data of the first image pattern and the difference pattern. The invention also provides an automotive lighting device configured for the method.

A hybrid germicidal irradiation apparatus, method, and system for multi-band germicidal irradiation. A first emitter, a second emitter and a third emitter may be coupled to a housing configured to be coupled to a ceiling of an interior room. The first emitter, the second emitter and the third emitter may respectively be operable to emit UV-C radiation at a wavelength of about 265 nanometers, near-UV radiation at a wavelength of about 405 nanometers and visible light at a wavelength greater than 405 nanometers. One or more radiation sensors may be configured to measure the amount of UV-C light, near UV-C light and/or visible light reflected from a target surface. A controller may be communicably engaged with the radiation sensors to calculate an amount of UV-C radiation, near-UV radiation and/or visible light delivered to a target surface or interior space.

Methods and systems are provided for calibrating a UV lamp having a plurality of arrays or channels of light emitting diodes. The calibration involves adjusting a drive current applied to the UV lamp based on an actual irradiance output by its light-emitting diodes relative to a target irradiance. The calibration is selectively performed when a stabilized temperature condition of the lamp is met.
