Abstract

An original express method of analysis of LED lamps to determine the main values of their energy efficiency is considered on the example of street lamps Street-100 Eco, Gemera-100 and SL-96. During the research, the influence of the geometry of the illumination beam on the characteristics of scattered light and the bandwidth of a diode array spectrometer was taken into account. The authors analyzed LED products for lighting purposes on a global scale over the past decade. The completeness of the analysis of the work carried out allows the authors to derive multipliers and propose a formula for a simplified calculation of the luminous flux. For the study, a laboratory stand was created, and the dependences of illumination on time were obtained. This methodology was developed taking into account the needs of the Kazakhstani consumer market of LED products for lighting purposes, where there is a need for product quality control on the buyer's side, without burdening him with expensive equipment and allowing for an initial assessment in the shortest possible time
