    摘要: Adjusting a driving signal for a lighting device by obtaining a temperature of the lighting device, and adjusting at least one parameter of a conversion procedure depending on the obtained temperature. Further a set-point of a desired colour and/or brightness is converted into a set-point of colour sensor coordinates with the conversion procedure. The actual colour values of the lighting device are obtained, and the driving signal is adjusted based on a difference between the colour sensor coordinates set-point and the obtained colour values.

    摘要: In a method and a driver circuit for operating one or more light emitting diodes, LEDs, an alternating supply current is generated and transformed to an alternating secondary winding voltage. Using rectifier means, such as diodes or synchronous switches, the alternating secondary winding voltage is converted to a substantially constant load current by using a buffer element, such as an output choke, i.e. a suitable inductor. The power transferred from the power source to the LEDs may be controlled by frequency control of the alternating supply current.

    摘要: Disclosed is a light module package including a mounting substrate for mounting and electrically contacting at least one light emitting diode and a ceramic layer disposed in a path of light emitted by the light emitting diode. The ceramic layer includes a wavelength converting material and the light emitting diode is disposed between the ceramic layer and the mounting substrate. The light module package also includes a light sensor disposed at the mounting substrate for detecting a luminous output of the light emitting diode in order to control the brightness and/or the color of the light leaving the light module. The ceramic layer is only partly translucent to shield the light sensor against ambient light.

    摘要: The present invention relates to a device and method for controlling the color point of an LED light source (50). Color point control is a most interesting product feature both for white and colored LED light sources. In known methods for the color control of RGB LED light sources use is made of flux and color sensors. However, there are difficulties with respect to sensing quickly changing ambient light, deeply dimmed colors, coordinating the measurements with the switching of the LEDs, and controlling the color in LED light units comprising a number of independent LED lamps, e.g. segmented wall washers and LCD backlights. It is proposed according to the present invention to control the color of the LED light source (50), using a model-based feed forward approach. Factors relating the parameters controlling the LED currents to the brightness for the different colors (and segments) are stored and used for open loop control. A slow-running procedure continuously measures and updates these factors. Whilst the measurements are e.g. synchronized with the PWM, the procedure itself can run considerably slower and updates the factors asynchronously.

    摘要: A driver circuit for operating one or more light emitting diodes(LEDs) is disclosed. An alternating supply current is generated and transformed to an alternating secondary winding voltage. Using rectifier means, such as diodes or synchronous switches, the alternating secondary winding voltage is converted to a substantially constant load current by using a buffer element. The buffer element comprises an output choke, such as an inductor. The power transferred from the power source to the LEDs may be controlled by frequency control of the alternating supply current.

    摘要: Operating a lighting device by acquiring a target brightness level of at least one solid-state lighting unit, and determining a reference driving current amplitude for obtaining the target brightness level. If the reference driving current amplitude is below an optimum driving current amplitude, the solid-state lighting unit is operated at the optimum driving current amplitude, which is pulse-width modulated to obtain the target brightness level.
