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： 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 light source that generates light that is perceived to have a predetermined color is disclosed. The light source includes first and second red LEDs and a non-red light emitter. The first and second red LEDs emit light in the red portion of the spectrum but at different wavelengths. The non-red light emitter emits light at a wavelength in a non-red portion of the spectrum. A controller varies the intensity of the first and second red LEDs to provide a combined light signal that is perceived as having the predetermined color. In one embodiment, the non-red light emitter includes a fluorescent light, and the controller adjusts the intensities of the red LEDs to provide a source that is perceived as an incandescent source of a predetermined color temperature.

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： In one embodiment, a user-selected color point is received. RGB tristimulus values are then derived for the color point. It is also determined whether the user-selected color point is outside a color selection range of the LED light source and, if so, an error flag is set. Pulse width modulated signals for a plurality of LED drivers for the LED light source are also generated. In another embodiment, tristimulus values representing a color of light produced by an LED light source are received. The received tristimulus values are then compared to tristimulus values corresponding to a user-identified color point. In response to the comparison, pulse width modulated signals are generated for a plurality of LED drivers for the LED light source. After a predetermined number of repetitions of these actions, an error flag is set if the user-selected color point has not been achieved by the LED light source.

摘要： Optical feedback for controlling color of light from a light source is provided. Incident optical energy of the light is detected as a function of discrete steps of wavelength. For each discrete step of wavelength, an X, Y and Z tristimulus subvalue is produced. All the X, Y and Z tristimulus subvalues for all the discrete steps are summed together to produce an X, Y and Z tristimulus value for the light. The X, Y and Z tristimulus values are used as feedback in controlling color of the light generated by the light source.
