    • A method and a multispectral color coordination system simulates high-quality daylight spectra. Light is produced with LEDs disposed in groups. Each group emits light at different wavelengths within the daylight spectrum. The wavelength of the light emitted by each LED at different working temperatures and different PWM values is measured. The measurement results for each LED are stored in memory, with assignment to working temperatures and PWM values. The LEDs are actuated at values selected from the memory content, as a function of the light to be emitted by each group. The working temperature of each individual LED chip is constantly measured and compared with the values stored in memory with regard to the current working temperature, and, in case of deviation compensated for by recalculating the spectrum, taking into consideration the PWM values stored in memory for the working temperature, and actuating with these.
    • 一种方法和多光谱色彩协调系统模拟高品质的日光谱。 光以LED组合的方式产生。 每组在日光谱内发射不同波长的光。 测量在不同工作温度和不同PWM值下每个LED发出的光的波长。 每个LED的测量结果存储在存储器中,分配到工作温度和PWM值。 LED作为每个组要发射的光的函数从存储器内容中选择的值被致动。 不断测量各个LED芯片的工作温度,并将其与存储在当前工作温度中的值进行比较,并且在通过重新计算光谱补偿偏差的情况下,考虑到存储在存储器中的PWM值 工作温度,并用这些驱动。

    • Polyamides based on dicarboxylic acids and on diamines are produced in a batch process by 1) feeding the entire amount of monomer composed of dicarboxylic acids, of diamines, and, if appropriate, of further polyamide-forming monomers, in the desired stoichiometry, in a closed stirred-tank reactor, 2) heating the monomer mixture in the stirred-tank reactor, with stirring, and with setting of a certain pressure, to a desired reaction temperature for the production of a prepolymer, 3) if appropriate, completely or partially depressurizing the reaction mixture from stage 2), 4) if appropriate, carrying out further thermal treatment of the reaction mixture from stage 2) or 3), and 5) reacting the reaction mixture from stage 2), 3), or 4) in the melt in a vented extruder for further increase of the molecular weight, with discharge of water vapor, and without use of additional polyamide-forming monomers or of polyamides.
