ESTIMATION OF THE AUTHENTICITY OF THE PROCEDURE OF THE DETERMINATION OF THE RATING HOUSING AND COMMUNAL SERVICES OF LED-LAMPS AND LAMPS OF THE DIFFERENT FIRMS
The work is aimed at establishing methods for determining the level of confidence in the rating industry LED lamps and LED lamps which are widely used for a number of years in the publications of the magazine «Modern lighting fixtures». To speed up the analysis of the data presented in these sources, and improve the accuracy of its calibration curve performed for scoring 8 basic parameters of LED lighting products. Established step and nonlinear character of their changes, which often leads to an overestimation or underestimation of the value of each parameter on the 5–8 score and final score respectively ±10–30 %. A significant deviation of the calibration curves on their linear approximation shows non-identical qualifications of experts involved. The simultaneous use of 5, 11 and 17 point scale makes it impossible to conduct systematize these results. Erroneous application of scoring parameters such as luminous flux and the cost of fixtures further introduces an error in the final assessment. The results indicate that individual luminaires previously «low-rated» pass in the category of good, and the good in the bad category. This greatly affects the reliability of the considered methods for determining the ranking of LED lamps and LED lamps. The necessity to develop a new method of quality control of LED lighting without the involvement of experts.
