    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: The invention relates to a light application apparatus (1) for applying light to an object (3). A light source (4) generates processing light (2) and sensing light (5), which are coupled into the object (3). A light detector (8) detects the sensing light (5) after having left the object (3), and a control unit (9) controls the light source (4) such that processing light (2) in a processing time interval and sensing light (5) in a sensing time interval are alternately generated. Since processing light and sensing light are generated alternately, the generation of the processing light and of the sensing light is decoupled, i.e. the processing light can be optimized for processing purposes and the sensing light can be optimized for sensing purposes. This allows improving the quality of sensing the object and, thus, the quality of controlling the application of light depending on properties of the object.

    摘要: This invention relates to a color controlled light source comprising a plurality of colored light elements; a detector for detecting the light output of the light source and generating a detection signal; and a color control unit for generating driving signals to said light elements on the basis of said detection signal and a predetermined target color point of the light output of the light source. In order to enable detection of contributions from individual light elements to the light output of the light source, the light source further comprises a modulator for individual signature modulation of the driving signal to each one of said light elements; and a corresponding demodulator for demodulation of said detection signal and generation of actual, i.e. measured, values of the output of the individual light elements. The color control unit determines nominal values of the light output of each light element for obtaining said target color point, and compares the actual values with the nominal values. If there is a difference, it adjusts the driving signals in order to minimize the difference.
