INVESTIGATION OF THE CHARACTERISTICS OF THE LED LUMINAIRE WITH VARIABLE LIGHT DISTRIBUTION FOR LIGHTING OF TRADING AREAS

Abstract

In this work, the concept of creating a lamp with a variable light distribution in a single housing was chosen, the characteristics of the uniformity of illumination, the values of the average brightness over the studied surfaces of the developed lamp layout with LED light sources were analyzed. As LED light sources, lamps of the MR16 type are used with an emission angle of 36 degrees, a power of 4.5 W, a luminous flux of 400 lm, a color temperature of 3000 K at a temperature of 36 oC, with an angle of 80 degrees, a power of 5 W, a luminous flux of 305…315 lm, color temperature 4000 K, with an emission angle of 100 degrees, a power of 5 W, a luminous flux of 440 lm. An analysis of the measurement results allows us to conclude that the color temperature of the lamps is close to the parameters declared by the manufacturers. 3 lighting projects were created. For each project, 4 lighting options were made with different combinations of lamps.Suspensions were used to save energy and increase light output. The result of this study was data on the use of the developed lamp. It was found that the lamp has a great potential for use, due to the fact that it has the possibility of using various LED lamps and due to the mobility of its individual modules. When combining lamps with radiation angles (from right to left): 36, 36, 100, 36, 36 and using a 0.3 meter long suspension, the most optimal lighting option is achieved.
