摘要： A light source and method for controlling the same. The light source utilizes a light generator that generates a light signal of a wavelength at an intensity that is set by a control signal. The control signal is controlled by a servo that monitors the light output of the light generator and compares the monitored value with a target value. When the target value is changed, the control signal is initially replaced by a predicted control signal based on the new target value rather than the error signal generated in the servo. This provides time for the servo to adjust to the new target value. In one embodiment, the control signal includes a periodic signal that switches between a value that causes the light generator to generate light of the wavelength and a second value at which the light generator does not generate light of the wavelength.

摘要： A technique for controlling a Light Emitting Diode (LED) based light system involves driving individual light sources that make up the LED-based light system at non-overlapping intervals so that light source-specific feedback signals can be generated in response to the emitted light. The light source-specific feedback signals are then used to individually adjust the light sources to achieve desired luminance and chrominance characteristics of the emitted light.

摘要： The present invention includes a light source having N light generators, a receiver, and an interface circuit. Each light generator emitting light of a different wavelength, the intensity of light generated by the kth generator is determined by a signal Ik coupled to that light generator. The receiver receives a color coordinate that includes N color components, Ck, for k=1 to N, wherein N is greater than 1. The interface circuit generates the Ik for k=1 to N from the received color components and a plurality of calibration parameters. The calibration parameters depend on manufacturing variations in the light generators. The calibration parameters have values chosen such that a light signal generated by combining the light emitted from each of the light generators is less dependent on the manufacturing variations in the light generators than a light signal generated when Ik is proportional to Ck for k=1 to N.

摘要： A color management system for a field sequential lighting system. The color management system includes a plurality of light sources, a driver circuit, and a controller. The driver circuit is coupled to the plurality of light sources, and the controller is coupled to the driver circuit. The driver circuit drives the plurality of light sources. The controller generates first and second control signals for a first subframe of a temporal sequence of subframes. The first control signal corresponds to a first light source of a first color which is a primary color for the first subframe. The second control signal corresponds to a second light source of a second color which is a supplemental color for the first subframe. Embodiments of the color management system maintain a color point of the primary color of each subframe.

摘要： A system and method for generating white light involves using a combination of phosphor-converted white LEDs and non-phosphor-converted color LEDs to produce white light and adjusting the emitted light in response to feedback signals. Generating white light using a combination of phosphor-converted white LEDs and non-phosphor-converted color LEDs produces white light with an improved CRI and a wide SPD. Adjusting the emitted light in response to feedback allows luminance and chrominance characteristics of the white light to be controlled as the performance of the LEDs changes over time. The emitted light can be adjusted on a per-color basis and/or on a per-group basis, where a group of LEDs includes a combination of at least one phosphor-converted white LED and at least one non-phosphor-converted color LED.
