    摘要: Disclosed herein is a system for controlling a drive current of an LED that includes a controller configured to estimate a junction temperature of the LED at a location of a heat sink. The system also includes a driver configured to change a drive current to the LED in response to a command from the controller. Also disclosed is a method of determining drive currents for LEDs in an array that includes determining a required light output intensity at a first time for each LED; estimating heat generated by each LED at the first time; solving heat flow equations for the array at the first time; estimating a junction temperature for each of the LEDs at the first time; and determining a drive current for the required light intensity at the first time for each of the LEDs based on the junction temperature.

    摘要: Disclosed herein are methods and systems for emitting light that can provide a desired light-induced physiological stimulus and a desired luminous stimulus. The light can be controlled to vary the physiological stimulus within a predetermined first range while maintaining the luminous stimulus within a predetermined second range that is useful for a number of self and/or space illumination applications. For example, an apparatus may include a controller for controlling the drive currents supplied to a plurality of light-emitting elements having different spectral characteristics, wherein the combination of currents is controlled such that the mixed light emitted is associated with the desired physiological and luminous stimuli.

    摘要: The invention relates to a light treatment system (10, 12). The light treatment system comprises a light source (20, 22) for emitting light (100) for illuminating a part of a human or animal body (30) for light treatment. The light treatment system further comprises a housing (40, 42) for emitting light towards the part of the human or animal body, and for at least partially covering the illuminated part of the human or animal body from view. The housing further comprises a window (50, 52, 54, 56) for emitting light from an inner part of the housing away from the housing. An effect of the light treatment system according to the invention is that the window in the housing may be used as indicator whether the light treatment system is operating and/or functioning well. Furthermore, the presence of a luminescent material, for example, on the window, may be used as indicator for, for example, ultraviolet light as part of the ultraviolet light may be converted by the luminescent material into visible light.

    摘要: A controller, method and system, for controlling lighting responsive to ambient lighting conditions are described. In particular, disclosed is illumination controller (110) for controlling illumination of a workspace near a display (253). The illumination controller includes a memory device (113) storing a user's preference for illumination of the workspace; a processor (111) accessing the user's preference in the memory device; and an interface (112) between the processor and an electronic sensor (231) located proximate to the display, which collects a reading from the electronic sensor. The processor compares the reading with the user's preference, and sends a command to at least one luminaire (241) to adjust the illumination of the workspace. The electronic sensor can be, for example, a photosensor, an occupancy sensor, an orientation sensor, or a location sensor. In some embodiments, the interface collects the reading from the electronic sensor via a wireless communication link.
