    • A light emitting diode (LED) lighting system for producing white light is disclosed. The system comprises sets of LEDs arranged to emit light with different wavelength ranges and associated with different sets of characteristics, and a driving circuit arranged to drive the LEDs. The driving circuit comprises an input for desired light intensity, color rendering index, and color temperature, an input for signals for LED temperature, a model for determining driving currents for said sets of LEDs from said parameters, signals, and characteristics for each of said sets of LEDs; and a current driver for the LEDs. At least one of the sets of LEDs comprises a first subset of LEDs with a first wavelength sub-range and a first set of characteristics, and a second subset of LEDs with a second wavelenght sub- range and a second set of characteristics. A lumped wavelength range of the set of LEDs is a range of said first and second wavelength sub-ranges, and the set of characteristics of the set of LEDs is a function of said first and second sets of characteristics. A method for controlling the sets of LEDs is also disclosed.

    • The present invention relates to a color variable light-emitting device comprising an array of a plurality of LEDs formed on one highly resistive substrate, which array comprises a first, a second and a third set of at least one LED arranged to provide light of a first, a second and a third color, respectively. At least one of the sets is independently addressable. Further, each light-emitting diode in the array has a separate connection to a circuitry, and at least one of the sets comprises at least two LEDs, interconnected in series via the circuitry. Thus, all connections between separate LEDs, for example in the same set, can be done via the circuitry. This also allows for a very dense packing of the LEDs in the array, as no interconnects between different LEDs of the array need to be arranged in the array.
    • 本发明涉及一种彩色可变发光装置,其包括形成在一个高电阻衬底上的多个LED的阵列,该阵列包括第一组,第二组和第三组至少一个LED,该至少一个LED布置成提供 第一,第二和第三种颜色。 至少有一组可独立寻址。 此外,阵列中的每个发光二极管具有与电路的单独连接,并且至少一个组包括经由电路串联互连的至少两个LED。 因此,例如在同一组中的分离的LED之间的所有连接可以经由电路完成。 这也允许在阵列中的LED的非常密集的堆积,因为阵列的不同LED之间的互连不需要排列在阵列中。
