Mikaeva S. A., Mikaeva A. S., Galtsova E. M., Zimin D. I. Abstract. The paper presents the results of a study of lighting conditions generated by the led to radiation sources. Evaluation of light environment created lighting system with LEDs was conducted on the level of visual performance. Determination of the most favourable light conditions for objects III discharge of the visual SP. To assess the conditions of illumination produced by the LEDs, in the present work were studies of visual performance depending on the level of illumination of the working surface. Experimental setup represented in the form of adaptive camera size 1,3 × 0,65 × 0,70 m, the internal surface of which was covered with a white diffuse-reflective material with a reflection coefficient of 0,8. Lighting was provided with the light fixture above the object of observation at a height of 0,5 m above the working surface. As the radiation source used light-emitting diodes of high intensity type U-337. The outlet of the light unit is blocked by the lens. The level of illumination of the working surface was changed from 100 to 1000 Lux by regulating the voltage of the power source. The uneven lighting of the surface did not exceed ±10 %. Illumination measurements were carried out using a light meter “TKA – Suite” with the permissible limit values of the relative error is ± 6%. The visual task is to find in the table above, and the omission of all rings with a certain direction of the gap. Using the stopwatch recorded time job and was determined by the number of errors separately by type (missing rings and mistakenly erased). It is found experimentally that for the test object with an angular size = 4' when the luminance level is equal to 700 Lux, visual performance is characterized by the least number of errors. To further increase the light level does not reduce the number of errors, that is characterized by its stability, therefore, to perform the specified type of visual work, this level of illumination of the working surface can be defined as optimal for the minimum number of errors during the experiment. Keywords: Lighting system; Illumination; LEDs; Angle size; Visual performance; Visual era.
