AB  - This article aims to investigate the influence of temperature and drive current
      on the spectral and photometric characteristics of high-power Chip-on-Board
      (COB) LEDs. An analysis of variations in luminous flux, correlated color
      temperature (CCT), and color rendering index (CRI) is presented, accompanied by
      the development of analytical models describing their behavior. To achieve an
      accurate mathematical representation, a regression analysis method is proposed,
      enabling the formulation of precise theoretical dependences of luminous flux and
      CCT on the operating temperature and current of LEDs. The obtained results
      provide a scientific foundation for designing the energy-efficient lighting
      systems with stabilized photometric characteristics, suitable for industrial,
      biomedical, and photobiological applications. Furthermore, the findings offer
      promising opportunities for real-time prediction of temperature-induced
      degradation in LED performance.
