摘要： A light head for a medical device support system. The light head includes first and second zones of light sources, an optical system, and a control system. The first and second zones of light sources emit respective first and second beams of light that form an illumination pattern having a pattern size at a region of interest. The optical system adjusts a beam spread of the second beam of light to change the pattern size of the illumination pattern from a first pattern size to a second pattern size. The control system varies power to the first and second zones of light sources in response to adjustment of the beam spread of the second beam of light to maintain a substantially constant magnitude of illuminance at the region of interest as the pattern size is changed from the first pattern size to the second pattern size.

摘要： A control system for a switchable privacy display apparatus comprises an ambient light sensor, a controllable light source and a display controller arranged to control the light source and the display luminance. High image visibility is provided for public mode operation while in privacy mode visual security level above a perceived privacy threshold may be obtained by means of control of image luminance and display illuminance, in response to the output of the ambient light sensor.

摘要： A power generation system includes: at least one power generating device generating electric power by rotation of an input shaft; and a power storage circuit including at least one capacitor and storing energy of the electric power generated by the power generating device. The power storage circuit has a capacitance equal to or near an energy-maximizing capacitance, the energy-maximizing capacitance indicating a capacitance maximizing an upper limit energy in characteristics of energy to capacitance, the characteristics being calculated as the upper limit energy to be stored in the power storage circuit, with respect to the capacitance of the power storage circuit. The characteristics of energy to capacitance are calculated based on: the capacitance of the power storage circuit, an electromotive force of the power generating device, an internal resistance of the power generating device, and a duration of one power generating action of the power generating device.

摘要： Photographic lighting devices, systems, and methods having a plurality of electrical energy storage/discharge (EESD) elements and/or one or more light sources in a single photographic lighting device to perform one or more photographic lighting effects. EESD elements and one or more light sources can be configured to have multiple separate light emissions occur in a single image acquisition window. The multiple light emissions are separated in an image acquisition window by a time period that is about shutter speed exposure time/(N−1), where N is the number of light emissions. In one such example, two light emissions are separated by a time period that is about shutter speed exposure time/(N−1).

摘要： An embodiment relates to a light emitting module, a light emitting module manufacturing method, a light emitting cabinet, and a display device. The display device of an embodiment includes: a support frame; and a plurality of light emitting cabinets including a plurality of light emitting modules disposed on the support frame, wherein the plurality of light emitting modules may include a substrate, a plurality of light emitting units directly mounted on the substrate, and a black matrix disposed on the substrate to surround each of the plurality of light emitting units. The embodiment may implement uniform color and uniform brightness by providing a light emitting module providing full color, and may implement slimness and high brightness by simplifying a configuration of the light emitting module in a chip on board (COB) type. The embodiment may implement low power driving and improve productivity and yield by simplifying the configuration of the light-emitting module.
