Colour consistency is achieved by an arrangement where light of one or more of the light sources impinges on more than one light sensor. If constructional detector features, such as filter characteristics, coincide, then these sensors should in principle, after the appropriate processing, report identical colour points of the light source under consideration. Indeed, colour is a path-independent property of light, and this is the basis for a mutual calibration scheme of the detectors according to the invention.Type: ApplicationFiled: January 20, 2009Publication date: December 16, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Paulus Henricus Antonius Damink, Sel Brian Colak

The overall output of the driver circuit comprises a pulse width modulated output current which alternates between a high current (Ihigh) generated by the first driver circuit and a low current (Ilow) generated by the second driver circuit. By providing separate driver circuits for two different current requirements, the circuits can be optimised for each function.

Publication number: 20100315021Abstract: A microprocessor uses one or more output pins to pulse width modulate a charge pump network to achieve a boosted voltage on an output port. The boosted voltage is then used to drive an LED, which may have a higher voltage drop than that of the starting un-boosted voltage. The adjustment of either the frequency or duty cycle of the PWM signal allows for adjustment of the steady state output voltage. This allows for the adjustment of the brightness of the LED by firmware while supplying enough voltage drop required by the LEDs.Type: ApplicationFiled: June 11, 2010Publication date: December 16, 2010Applicant: AERIELLE TECHNOLOGIES, INC.Inventors: Francis Lau, John R.
