Аналіз спектральних характеристик світлодіодних світлосигнальних світильників

The relevance of the use of light signal lamps is due to the growing requirements for safety, energy efficiency and reliability of technical systems in various fields of activity. Light signal devices provide prompt information to users about the status of objects and processes, contribute to the prevention of emergency situations and increase the level of organization of traffic and production operations. The use of modern LED technologies in the design of lamps allows to achieve high light output, long service life and reduced energy consumption, which corresponds to modern trends in the development of energy-saving technologies. As a result, light signal lamps are an integral element of the transport, industrial and urban environment infrastructure, providing an effective combination of functionality and safety. For marking and warning lamps (signal, aeronautical, etc.), it is critical to ensure stable color and photometric characteristics that determine the level of visibility and recognition of the signal. LED sources used in such devices are characterized by a complex spectral composition of radiation, which must be investigated by spectrophotometric methods. Measurement of spectral power distribution (SPD) allows you to determine color coordinates, color temperature, color rendering index and other parameters, which are the basis for assessing compliance with regulatory requirements.
