Abstract: A light emitting assembly includes a first light emitting component, a second light emitting component, and a third light emitting component. The components are arranged such that a first light, a second light and a third light mix to form a mixed light. The assembly includes a control device, which has a first control channel and a second control channel operating the three components and configured such that in a first operating range the first component is driven via the first channel and the second and third components are driven jointly via the second channel. In the first operating range the mixed light is continuously adjustable from the first color to a fourth color, and in a second operating range the second component is driven via the second channel and the first and third components are driven jointly via the first channel.

Abstract: A pre-calibrated light box includes a light panel, a material attached to the light panel and at least one LED strip positioned inside the light box and including a plurality of interweaved LEDs selected from three different bins on a chromaticity diagram. The three different bins are selected based on plotting a representative vertex inside each of the first, the second and the third bins and drawing a triangle between the vertices so that a target color of white light emitted out of the light box is located inside the drawn triangle. At least three channels are electrically coupled to each of the bins of LEDs and each channel powers the corresponding bin of LEDs with a proportion of power determined by a geometric location of the target color of white light with respect to a location of each of the bins on the chromaticity diagram.

Abstract: A light source is provided that includes at least two semiconductor light-emitting elements that emit light of different color, a light guide, an electronic control unit, and a light sensor. The light emitted by the elements is injected, at least partially, into the light guide and exits laterally from the light guide. The brightness of the elements can be adjusted by the electronic control unit. The light sensor is arranged to receive the light injected by the elements and laterally exiting from the light guide. The electronic control unit accumulates sensor signals from the light sensor over an integration time interval and compares the accumulated signals with a target value or range to determine a difference, changes a brightness of the elements in response to the difference, and changes the integration time interval in response to the difference or to a change in the target value.

Abstract: To provide an illumination method and a light-emitting device which are capable of achieving, under an indoor illumination environment where illuminance is around 5000 lx or lower when performing detailed work and generally around 1500 lx or lower, a color appearance or an object appearance as perceived by a person, will be as natural, vivid, highly visible, and comfortable as though perceived outdoors in a high-illuminance environment, regardless of scores of various color rendition metric. Light emitted from the light-emitting device illuminates an object such that light measured at a position of the object satisfies specific requirements. A feature of the light-emitting device is that light emitted by the light-emitting device in a main radiant direction satisfies specific requirements.

Abstract: Devices, systems, and methods for automatically managing emergency lighting testing are generally described herein. The automated emergency lighting testing may include scheduling emergency lighting events, verifying that emergency lighting power sources and fixtures are sufficient to maintain requisite light intensity for a requisite amount of time, and calculating life expectancy for emergency power sources and lighting fixtures to predict when components should be replaced to avoid failure. The disclosure reduces the amount of time and manual intervention required for the tests by using, among other things, a system of lighting control drivers, sensors, and processors that monitor, assess, and control the lighting system including emergency lighting components and power.
