    Abstract: This invention relates to a color controlled light source comprising a plurality of colored light elements, and a plurality of (filtered) photo detectors, having different spectral characteristics covering all or most of the total spectrum of the light elements. The (filtered) photo detectors detect the light output of the light source, and generate corresponding detection signals. The light source further has a color control unit for generating driving signals to the light elements on the basis of the detection signals and a predetermined target color point of the light output of the light source, and a modulator for individual signature modulation of the driving signal to each one of said light elements. A corresponding demodulator is provided for demodulation of the detection signals and extraction, from each detection signal, of actual values of the light outputs of the light elements. The color control unit has means for determining the spectral output of each light element on basis of the actual values, means for determining an actual color point from said spectral outputs of all light elements, and means for comparing said target color point with said actual color point and, if there is a difference, adjusting said driving signals in order to minimize the difference.

    Abstract: Techniques are disclosed for manipulating both colored and tunable white lighting systems in order to enhance visual comfort and allow an observer's eyes to recover from exposure to colored light. A lighting system may gradually adjust the color, color temperature, and intensity of various multi-chip LED panels in order to provide pleasant and acceptable changes in light settings. Instead of abruptly switching from one light setting to another, a lighting system may fade to an intermediate transition setting and subsequently fade to the final light setting, allowing an observer's eyes time to adapt to the new light settings. In one example, switching from blue light to a neutral white light may involve a gradual fading from blue light, to a cool white light, and then to a neutral white light, thus allowing the end user's eyes to adapt to the new light settings.

    Abstract: Systems and methods for using an LED-based lamp for reproducing a target light are disclosed. A color-space searching technique is introduced here that enables the LED-based lamp to be tuned to generate light at a specific CCT by adjusting the amount of light contributed by each of the LED strings in the lamp. The target light is decomposed into different wavelength bands, and light generated by the LED-based lamp is also decomposed into the same wavelength bands and compared. The color-searching techniques allow the LED-based lamp to closely emulate a black body radiator given the limitations of the physical specification of color string in the LED strings.

    Abstract: A solid-state lighting device includes light source, light emitting, light receiving and light guiding sections, and a protection circuit. The light source section has a semiconductor laser including a light emitting layer and a driving circuit. The light source section emits light with a bluish purple to blue wavelength range. The light emitting section includes a heat conduction part which includes a wavelength conversion layer absorbs the light and emits wavelength-converted light, and an optical part which guides the light. The light receiving section detects returning light from the optical part. The light guiding section guides the light from the light source section toward the optical part, and guides returning light therefrom toward the light receiving section. The protection circuit outputs a driving stop signal to the driving circuit, which stops driving the semiconductor laser, if the amount of the returning light detected is not within a prescribed range.

    Abstract: The present disclosure relates to an LED-based lighting component that can control the color rendering capability of its generated light based on the presence or characteristics of ambient light. In one embodiment, the lighting component may employ at least two different types of LEDs to generate light. Control circuitry of the lighting component is able to monitor ambient light and drive the LEDs based on an ambient light characteristic that is indicative of the CRI of the ambient light. If the ambient light characteristic is indicative of the ambient light having a lower CRI, the control system will drive the LEDs to emit light with a defined CRI. If the ambient light characteristic is indicative of the ambient light having a higher CRI, the control system will drive the LEDs to emit light with a reduced CRI, which is lower than the defined CRI.
